UK Tax Relief Guide (2026/27)

1. Overview: allowance vs relief vs deduction vs exemption

The UK tax code uses four overlapping concepts that the public conversation tends to lump together as "tax breaks". They mean specific, different things in HMRC documentation.

An allowance is a slice of income (or gains, or transfers) that is tax-free at source, applied automatically without any claim. The £12,570 Personal Allowance, the £20,000 ISA allowance, the £3,000 CGT Annual Exempt Amount, the £500 dividend allowance, the £1,000 Personal Savings Allowance for basic-rate payers - these are all allowances. You do not file anything to get them; the system simply does not tax income that falls inside them.

An exemption is an entire class of income or transfer that is removed from the tax base. ISA returns, the first £30,000 of redundancy pay, gifts between spouses for IHT, payouts from a qualifying life insurance policy, and Premium Bond prizes are all exempt. Exemptions are stronger than allowances because they apply regardless of size (an ISA can hold £500,000 and the returns are still 0% taxed).

A deduction is an amount subtracted from your gross income before tax bands are applied. Trading expenses, employee pension contributions under Net Pay arrangement, certain employment expenses on a P87, and mileage allowance relief are deductions. Mechanically you pay tax on the smaller "net" figure rather than the gross.

A tax relief is a reduction in the tax bill itself, either through a deduction-style mechanism or via a direct rebate of tax already paid. Gift Aid (the higher-rate element), EIS / SEIS / VCT income tax credits, pension relief under Relief at Source for higher-rate payers, and Marriage Allowance are all reliefs. Most reliefs require an explicit claim - on Self Assessment, via a P87 form, or by writing to HMRC. The difference matters because unclaimed reliefs are money you have already paid in tax that you have a legal right to get back; HMRC will not chase you to claim them.

Throughout this guide we use the colloquial label "relief" for any tax-reducing mechanism (since that is what readers search for), but the technical category for each entry is flagged where it matters. For terminology drill-down see the UK tax glossary (sorted A-Z, 150+ defined terms).

2. Personal Allowance and adjustments

The Personal Allowance is the bedrock relief on which everything else stacks - the first slice of income that escapes Income Tax entirely. In 2026/27 the standard allowance is £12,570, set in the Income Tax Act 2007 and frozen by the Autumn Statement 2022 fiscal package through 2027-28. Three named adjustments can move the effective allowance up or down depending on circumstances.

Marriage Allowance. A spouse or civil partner who earns below the Personal Allowance (i.e. currently paying no Income Tax) can transfer 10% of their PA - £1,260 - to the higher-earning partner, provided that partner is a basic-rate (20%) taxpayer. Mechanically this gives the higher earner a tax code with M suffix (PA = £13,830) and the lower earner an N suffix code (PA = £11,310). The headline saving is £1,260 × 20% = £252 per year, plus backdating up to four prior tax years if eligibility applied. Higher-rate payers (income over £50,270) cannot claim it. Run your eligibility check on the marriage allowance calculator and apply directly at gov.uk/marriage-allowance.

Blind Person's Allowance. Registered blind taxpayers in England and Wales (or those certified severely-sight-impaired in Scotland and Northern Ireland) get an extra £3,250 on top of the standard PA in 2026/27, uprated each April. If your income is below the combined PA + BPA you can transfer the unused balance to a spouse or civil partner, similar to Marriage Allowance. The allowance is automatic once HMRC sees the council blindness register entry or the consultant ophthalmologist certificate, but in practice many newly-registered people have to phone HMRC to trigger the code update.

The £100k taper (the 60% trap). The Personal Allowance is not flat across all incomes. Above £100,000 of adjusted net income the allowance withdraws by £1 for every £2 of additional income, hitting zero at £125,140 and creating an effective 60% marginal rate on the £25,140 band in between (40% Income Tax on the slice itself plus 40% on the £1 of PA lost for every £2 earned). Pension contributions, Gift Aid and EIS all reduce adjusted net income for taper purposes - a higher earner targeting income just under £100,000 can escape the trap entirely through a single salary-sacrifice lever. Model your exposure with the 60% tax trap calculator or read the dedicated 60% tax trap explainer. Above £125,140 the PA is fully tapered to zero, meaning every £1 of additional income enters the additional-rate band at 45%.

Worth flagging: the Personal Allowance is not aggregated across the household. Two earners on £50,000 each pay much less tax than one earner on £100,000, because each gets a separate £12,570 PA and avoids the higher-rate band entirely. For families with one breadwinner near or above £100k, income-shifting strategies (spousal contracting, dividend allocation in a family company, maxing the spouse's pension) are among the most efficient structural moves in the UK system. See Personal Allowance explained for the full mechanics.

3. Pension contributions

Pension contributions are the single most powerful tax relief available to UK earners, and the only relief that can simultaneously reduce Income Tax, employee NI, employer NI, the Personal Allowance taper, the High Income Child Benefit Charge and the Tapered Annual Allowance threshold. The mechanics depend on which of three contribution methods your scheme uses.

Annual Allowance: £60,000. The standard cap on combined employee plus employer pension contributions across all your pensions in a tax year while still attracting tax relief. The limit is also constrained by "relevant UK earnings" - you cannot contribute more than your taxable earnings in any one year (or £3,600 gross if you have no earnings, the universal minimum). Excess contributions trigger an Annual Allowance Charge at your marginal Income Tax rate, paid through Self Assessment. Defined benefit schemes use a "Pension Input Amount" formula (16x the increase in accrued annual pension) rather than contributions; this often blindsides high earners in NHS, teachers' and Civil Service schemes who breach the AA without ever writing a contribution cheque.

Tapered Annual Allowance. The £60k AA reduces by £1 for every £2 of "adjusted income" above £260,000, to a floor of £10,000 once adjusted income tops £360,000. Adjusted income includes salary, bonus, BIK, investment income and employer pension contributions - so a senior consultant or partner with employer pension over £30k can hit the taper at gross earnings well under £260k. Threshold income (a second test, broadly excluding employer pensions) must also exceed £200,000 for the taper to apply, providing a "carve-out" for people with very large pensions but lower total income. Model the full interaction with our pension annual allowance calculator.

Money Purchase Annual Allowance (MPAA): £10,000. Once you flexibly access a defined contribution pension via drawdown or Uncrystallised Funds Pension Lump Sum (UFPLS), the AA drops permanently to £10,000 for any further DC contributions. The MPAA is designed to prevent retirees "recycling" tax-free cash back into new pensions to harvest duplicate relief. It does not affect defined benefit accrual, and is not triggered by taking only the 25% tax-free lump sum without drawdown (a Pension Commencement Lump Sum on its own does not start MPAA).

Three contribution methods, three relief mechanics.

• Net Pay arrangement. Pension is deducted from gross pay before PAYE is calculated. Income Tax relief is automatic at your full marginal rate (so a higher-rate payer gets 40% relief without any further action). NI is not relieved - the employee NI of 8% / 2% still applies to the original gross. Standard for older occupational schemes and many defined benefit schemes.
• Relief at Source (RAS). Pension is paid from net (post-tax) pay. The scheme administrator claims 20% basic-rate relief back from HMRC and adds it to your pot, so an £80 contribution becomes £100. Higher-rate and additional-rate payers must claim the extra 20% or 25% themselves via Self Assessment - it is not given at source. RAS is the default for personal pensions, SIPPs and most modern workplace schemes including the National Employment Savings Trust (NEST). The unclaimed higher-rate relief problem is estimated by HMRC at around £1.3 billion per year of foregone relief.
• Salary sacrifice. You contractually agree to a lower gross salary; the employer pays the sacrificed amount into your pension. Income Tax is saved, employee NI is saved (8% / 2%), and crucially the employer's 15% NI is also saved. Most employers reinvest some or all of the employer-NI saving into your pot, which makes salary sacrifice substantially more efficient than RAS or Net Pay for the same target contribution. Best mechanism by a wide margin for higher earners, and the standard mitigation for the £100k taper and the £60k HICBC.

Carry forward. Unused Annual Allowance from the prior three tax years can be added to the current year's AA, provided you were a member of a registered pension scheme in each of those years (a single £3,600 contribution to a SIPP is enough to establish membership for carry-forward purposes - a useful one-off move for someone anticipating a large future bonus or business sale).

For the detailed mechanics, comparison tables and worked examples by contribution method, see pension tax relief guide or run scenarios through the pension contribution calculator and the salary sacrifice calculator. For the side-by-side cash-flow comparison between methods see salary sacrifice vs RAS.

4. Gift Aid

Gift Aid is the UK's headline charitable giving relief - it lets registered charities reclaim the basic-rate Income Tax that the donor already paid on the donation amount, and lets higher-rate and additional-rate donors claim the difference between their marginal rate and the basic rate back through Self Assessment. Two-thirds of UK adults donate to charity each year, but HMRC estimates only around 40% of eligible donations are claimed under Gift Aid - the rest is left on the table.

The 25% gross-up. When you tick the Gift Aid box, you are declaring that you are a UK taxpayer and have paid at least as much Income Tax (or CGT) as the charity will reclaim. The charity then submits a R68 (i) claim to HMRC and receives 25p for every £1 you donated - because £1 net is grossed up to £1.25 at the basic rate (£1.25 × 20% = £0.25). Total value to the charity: 125% of the cash you actually gave.

Higher-rate top-up. If you pay 40% or 45% tax, you are entitled to claim the difference between your marginal rate and the basic 20% rate on the gross donation. Mechanics:

• 40% (higher rate) payer: claim 20% of the gross donation back. A £100 net donation becomes £125 gross for the charity and gives you a £25 personal tax refund.
• 45% (additional rate) payer: claim 25% of the gross donation back. £100 net = £125 gross to charity + £31.25 personal refund.
• Scottish 42% / 45% / 48% payers: claim the differential through their SA return (22%, 25% or 28% of gross respectively).

You claim the higher-rate element on page TR4 of the SA100 Self Assessment return, or by writing to HMRC if you do not file SA. HMRC can also adjust your tax code mid-year to give the relief through PAYE if you supply an estimate of your annual giving - useful for regular donors who would rather see monthly cash flow than an annual refund.

Carry back to prior year. A useful timing lever: when you file your SA return for tax year X, you can elect to treat charitable donations made up to the SA filing deadline (31 January following year X) as if they were paid in year X. Useful when your tax bill in the prior year was higher (you got pushed into the higher band by a one-off bonus or sale) and you want to push the relief into that year. Tick the "carry back" box on the SA100; the donation effectively becomes year X for relief purposes.

Practical impact on adjusted net income. Gift Aid donations reduce adjusted net income for the Personal Allowance taper and HICBC calculations. A higher earner with income just over £100,000 can Gift Aid the excess to charity, escape the 60% trap, and effectively pay a 60% rate of relief on the contribution (the 40% tax saved plus the 20% restored PA). Same maths applies for HICBC: Gift Aid that brings adjusted net income below £60,000 eliminates the High Income Child Benefit Charge entirely.

5. EIS: Enterprise Investment Scheme

EIS is the UK's flagship venture-investing tax relief, designed to channel private capital into early-stage UK trading companies. The scheme has been running since 1994 and was extended through 2035 at the Spring Budget 2024. Six separate reliefs apply, layered on top of each other, which is why EIS sits at the centre of high-net-worth tax planning.

30% income tax relief. The headline. Invest up to £1,000,000 in qualifying EIS companies in a tax year and reclaim 30% of the investment against your Income Tax bill (raised to £2,000,000 if any of the excess over £1m is in Knowledge Intensive Companies). The relief caps at your actual Income Tax liability for the year - you cannot reduce your tax bill below zero. £100,000 invested gives a £30,000 tax credit, settled through Self Assessment after the company issues the EIS3 compliance certificate.

Three-year holding period. Income tax relief is clawed back if you sell the shares within three years of issue (or within three years of the company starting to trade, whichever is later). The relief is preserved if the company is wound up genuinely or you die while holding the shares.

Carry back to prior year. You can elect to treat an EIS subscription as if it were made in the prior tax year, claiming the relief against last year's tax. Useful when you had a one-off liquidity event (sale, bonus, IPO) in the prior year and missed the tax-year window. The carry-back is irrevocable once made.

CGT deferral. Any capital gain crystallised in the three years before or twelve months after the EIS subscription can be deferred by rolling that gain into the EIS shares - so a £500k gain on a sold business, deferred into £500k of EIS investment, postpones the £100k+ CGT bill until you sell the EIS shares (and can then be deferred again into a further EIS investment, indefinitely).

Loss relief. If the EIS company fails, the capital loss (net of the income tax relief already received) can be set against either income or capital gains in the year of loss. Worked example: invest £100k, claim £30k income tax relief, company fails, "at-risk" loss is £70k. A 45% additional-rate payer setting that against income saves £31,500. Total downside on a £100k investment: £100k - £30k - £31.5k = £38,500. EIS is the only UK relief that lets a higher-rate investor cap downside this aggressively while retaining the unlimited upside.

Capital gains exemption on disposal. After the three-year hold, any gain on the EIS shares is fully exempt from CGT - unlike other shares where the gain over the AEA is taxable.

Inheritance Tax: Business Relief. EIS shares qualify for 100% Business Relief from IHT after a two-year holding period (subject to the £1m combined APR+BPR cap from April 2026 per Autumn Statement 2024 - previously unlimited). An estate planning route for high-net-worth investors who can tolerate the underlying business risk.

The trade-off: EIS-qualifying companies must be unquoted, under seven years old (ten for Knowledge Intensive), have under £15m gross assets pre-investment and fewer than 250 full-time employees. Around 70% of EIS investments lose money or return less than the original cash; the tax reliefs are designed to make the diversified portfolio mathematics work despite that hit rate. Official guidance: gov.uk venture capital schemes tax relief for investors.

6. SEIS: Seed Enterprise Investment Scheme

SEIS is EIS's smaller, more generous sibling - same plumbing, higher relief rates, lower investment caps, designed for genuinely seed-stage companies. SEIS limits were doubled at the Mini-Budget 2022 and have remained at the new levels.

50% income tax relief. Invest up to £200,000 in qualifying SEIS companies per tax year and claim 50% back as an Income Tax credit. £200k invested gives £100k tax relief, settled through Self Assessment. The cap is per investor, not per company.

50% CGT reinvestment relief. Half of any capital gain reinvested into SEIS shares is exempt from CGT altogether (not deferred - eliminated). Cap is the lesser of 50% of the SEIS subscription or 50% of the gain. So a £200k SEIS investment can exempt £100k of capital gains from CGT permanently.

Holding period, loss relief, CGT exemption on disposal, IHT Business Relief. All identical to EIS - three years for income tax relief retention, loss relief on at-risk capital at marginal rate, full CGT exemption on gains, BPR after two years.

SEIS-qualifying company tests. Tighter than EIS: gross assets under £350,000, fewer than 25 full-time employees, trading for less than three years, and a £250,000 lifetime SEIS funding cap per company. Most companies use SEIS for the first £250k of seed funding then switch to EIS for later rounds. Combined SEIS + EIS reliefs can substantially reduce the effective downside on early-stage angel investments, which is why SEIS underpins much of the UK angel ecosystem outside London (the relief mathematics improves portfolio expected value enough to make seed-stage diversification viable for individual investors).

7. VCT: Venture Capital Trust

VCTs are publicly-traded investment trusts that hold portfolios of qualifying small UK trading companies (similar universe to EIS-qualifying). They give investors EIS-style tax reliefs without the concentration risk of picking individual companies, traded for slightly weaker IHT treatment.

30% income tax relief. Same headline as EIS: 30% of new VCT share subscriptions, up to £200,000 per tax year, claimed as an Income Tax credit on Self Assessment. Note: only new shares qualify - buying VCT shares on the secondary market does not give the income tax relief.

Tax-free dividends. All dividends from VCTs are exempt from Income Tax, regardless of the size of your holding. This is the structural advantage over EIS: VCTs tend to pay regular dividends (typically 5%+ annual yield), and that yield is entirely outside the dividend allowance / dividend tax bands.

Tax-free disposal after five-year hold. Sell the VCT shares after at least five years and any gain is fully exempt from CGT. Selling before five years triggers clawback of the income tax relief, similar to EIS.

No IHT Business Relief. Unlike EIS and SEIS, VCT shares do not qualify for the 100% BPR after two years - they are listed on the AIM market and the BPR treatment for AIM shares more broadly has been cut to 50% from April 2026. For pure estate-planning IHT mitigation, direct EIS is more efficient than VCTs.

VCT subscriptions tend to spike in March (tax-year-end) when high-rate taxpayers are looking for income tax relief against the current year's bill. Most VCT issuances close by the first week of April. Treat the relief as a five-year commitment minimum - early exit forfeits the headline 30%.

8. Charitable giving: other routes beyond Gift Aid

Gift Aid covers cash donations, but UK charity tax relief extends to several other forms of giving with their own mechanics.

Payroll Giving. Employees can donate to charity directly from gross pay through an HMRC-approved Payroll Giving scheme that the employer signs up to. The donation comes off before PAYE, so a £50 monthly donation costs a basic-rate taxpayer £40 net, a higher-rate taxpayer £30 net, and an additional-rate taxpayer £27.50 net. There is no upper limit. The advantage over Gift Aid is that higher-rate relief is automatic - no SA claim needed. The downside is that NI is not relieved (only Income Tax) and only around 10,000 UK employers offer a Payroll Giving scheme.

Gifts of shares and securities. Donating qualifying shares (typically listed shares or AIM shares), units in authorised unit trusts, or shares in OEICs to a charity gives a double relief: the gain is fully exempt from CGT, and the market value of the gift is deductible from income at your marginal rate. For someone holding shares with a large embedded gain who would otherwise pay 24% CGT plus a 40% income tax bill, gifting the shares instead saves both - and the charity receives 100% of the market value tax-free.

Gifts of land or buildings. Same treatment as shares: 100% CGT exemption on the gain and marginal-rate income tax deduction on the market value. Major gifts of land sometimes outpace cash donations from the same donor because the combined tax saving exceeds the cash they would have raised by selling.

Legacies to charity (IHT). Bequests to registered charities in a will are 100% exempt from Inheritance Tax. If you leave 10%+ of your net estate to charity, the IHT rate on the rest of the estate drops from 40% to 36% - a structural incentive to leave a meaningful legacy slice once an estate is clearly IHT-paying. Worked example covered in section 15 (IHT reliefs).

9. Mortgage interest (landlords) and Section 24

The single most-impactful tax change for UK private landlords since the 1990s. Pre-2017, landlords could deduct mortgage interest as a normal rental business expense, reducing taxable rental profit at their marginal rate. Section 24 of the Finance (No. 2) Act 2015 phased that out between April 2017 and April 2020 for individual landlords of residential property.

The new mechanic. Mortgage interest is no longer deductible against rental income. Instead, HMRC gives a "basic-rate tax reducer" - a tax credit equal to 20% of the interest paid, applied after the rental profit has been taxed at full marginal rates.

Worked example. A higher-rate landlord with £30,000 rental income, £12,000 of mortgage interest and £3,000 of other expenses:

• Pre-Section 24: profit = £30k - £12k - £3k = £15k, taxed at 40% = £6,000.
• Post-Section 24: profit = £30k - £3k = £27k, taxed at 40% = £10,800, minus £12k × 20% = £2,400 credit = £8,400 net tax.
• Effective increase in tax: £2,400 per year. Effective tax rate on profit: 56%.

The structural problem. Section 24 taxes revenue, not profit - landlords can owe tax in years where their actual cash-flow profit is zero or negative once interest is paid. It also pushes some landlords into the higher tax band because the gross rental income now stacks on top of their other income without the interest being deducted first, potentially triggering Personal Allowance taper and HICBC even at modest portfolio sizes.

The exemptions. Section 24 only applies to individual / partnership residential landlords. Three categories of property remain fully deductible:

• Limited company landlords deduct mortgage interest in full against corporation tax. Most BTL portfolios of 2+ properties acquired since 2017 are held in SPVs for this reason.
• Commercial property (offices, shops, light industrial) is fully deductible.
• Furnished Holiday Lettings (FHL): rules tightening from April 2025 per Autumn Statement 2024, but historically treated like a trade.

ONS landlord data shows the number of private landlords has fallen by around 17% since Section 24 was fully phased in, and Council of Mortgage Lenders data shows BTL purchases down 40% from the 2016 peak. Official guidance: gov.uk changes to tax relief for residential landlords.

10. Mileage allowance and capital allowances

Two reliefs that target the costs of doing your job: car / bike / motorcycle business travel, and the equipment you buy to do the work.

HMRC Approved Mileage Allowance Payments (AMAP). If you use your personal vehicle for business travel (excluding the ordinary home-to-work commute), HMRC publishes flat per-mile rates that an employer can pay tax-free. Anything paid above these rates is taxable as earnings; if the employer pays less or nothing, the employee can claim Mileage Allowance Relief (MAR) against the shortfall through a P87 form or Self Assessment.

Rates for 2026/27 (unchanged since 2011-12 - the 45p / 25p split was last uprated for the April 2011 tax year and remains a long-standing relief-erosion issue):

• Cars and vans: 45p per mile for the first 10,000 business miles in a tax year, 25p per mile thereafter.
• Motorcycles: 24p per mile (flat).
• Bicycles: 20p per mile (flat).
• Passenger payments (carrying a colleague on a business journey): additional 5p per mile per passenger, optional.

Worked example: an employee drives 8,000 business miles in their own car and the employer pays 30p per mile (£2,400 total). The HMRC-approved figure is 8,000 × 45p = £3,600. The shortfall is £1,200, which the employee claims at marginal rate via P87 - a 40% taxpayer saves £480. Model this with the mileage tax relief calculator. Authoritative rates: gov.uk travel mileage and fuel allowances.

Capital allowances. A relief that lets businesses (including sole traders, partnerships and companies) deduct the cost of "plant and machinery" against profits. Without capital allowances the depreciation of assets would not be tax-deductible at all, because accounting depreciation is added back when calculating taxable profits.

Annual Investment Allowance (AIA): £1,000,000. Permanently set at £1m from April 2023 after a decade of short-term extensions. Gives 100% first-year deduction on the first £1m of qualifying plant-and-machinery spend each year - so a sole trader buying £30,000 of tools and computers deducts the full £30,000 against the year's profits rather than depreciating it over five years. Cars are excluded from AIA and go into separate writing-down allowance pools (18% main rate, 6% special rate for cars with CO2 emissions over 50 g/km).

Full Expensing. A separate corporate-only relief from April 2023 (made permanent April 2024) giving companies 100% first-year deduction on new and unused main-rate plant-and-machinery, with no cap. Effectively replaces the AIA at the unlimited level for companies but does not apply to sole traders. The "first-year" relief is supplemented by a 50% first-year allowance for special-rate assets.

Electric vehicles. Zero-emission cars attract a 100% First Year Allowance (extended through March 2026 and likely to be replaced by a Full Expensing equivalent). Workplace EV charging infrastructure also qualifies for 100% First Year relief. Together with the ultra-low BIK rates for EVs on salary sacrifice (see section 13), this stacks into one of the most tax-efficient individual purchases available.

11. Working from home: employees

Since the pandemic the rules have tightened from the COVID-era blanket eligibility back to the original "homeworker by requirement" test, but a modest relief remains available for employees who genuinely need to work from home.

£6/week (£312/year) flat rate. If you are required by your contract to work from home some or all of the time (i.e. there is no employer-provided office available, or your role is structurally remote), you can claim £6 per week without any receipts as relief against additional household costs (heating, lighting, business proportion of broadband). A basic-rate taxpayer saves £312 × 20% = £62.40 per year; a higher-rate taxpayer saves £124.80. Claim via the gov.uk microservice for the current year or via P87 / Self Assessment.

Higher claims with evidence. If your actual additional costs exceed £6 per week (large home office, dedicated room used solely for work), you can claim the actual additional cost - but you must apportion the household bills by floor area and / or time, keep receipts, and be prepared to defend the calculation if HMRC enquires. Most employees do not bother because the flat-rate £6 is easier and the marginal gain rarely exceeds the record-keeping cost.

Hybrid working: a tightened test. If you have a desk available at the employer's office and you work from home by choice (a fairly common modern arrangement), HMRC's position since 2022 is that you do not meet the "required to work from home" test and cannot claim the WFH relief at all. The relief survives only where there is genuinely no workplace office, or where the contract mandates the home-office arrangement. Official guidance: gov.uk tax relief for employees working at home.

12. Professional subscriptions and tools

Two categories of employment-related cost that qualify for relief, both with the same general logic: the cost must be "wholly, exclusively and necessarily" required for your job, and must not be reimbursed by the employer.

Professional subscriptions. Annual fees to a professional body listed on HMRC's "List 3" are deductible against employment income at your marginal rate. List 3 has around 1,300 approved organisations covering most regulated professions in the UK:

• Chartered accountants: ICAEW, ICAS, CIMA, ACCA, CIPFA.
• Solicitors: SRA practising certificate, Law Society fees.
• Architects: ARB and RIBA.
• Engineers: ICE, IET, IMechE, RAeS.
• Healthcare: GMC, NMC, GPhC, HCPC, RCN, BMA, BDA.
• Teaching: NEU, NASUWT, NAHT.
• And around 1,290 others.

Typical claims £100-500 per year. A doctor paying £406 GMC and £473 RCS in 2026/27 (£879 total) at higher rate saves £351 of tax. Membership of non-approved bodies (chambers of commerce, trade associations, industry networks) is not deductible. HMRC List 3: gov.uk professional bodies approved for tax relief.

Tools and protective clothing. Trade employees who buy their own tools (mechanics, plumbers, electricians, builders, hairdressers) can claim either:

• HMRC's flat-rate allowance for their occupation (£60 to £185 per year depending on trade, no receipts needed); or
• Actual cost, with receipts.

Uniforms and laundering. If you wear a branded uniform or specialist protective clothing that cannot reasonably be worn outside work, you can claim a flat-rate uniform expense allowance - £60 standard, with specific higher rates for some trades (£140 for plumbers, £125 for joiners and carpenters). This is on top of the tool allowance. Claim via P87 (one-off or per-year) or through Self Assessment if you already file. Backdate up to four tax years - around 2 million UK trade employees are eligible but only ~750,000 claim, leaving an estimated £100m+ of relief on the table each year.

13. Employer-provided benefits exempt from tax

Several benefits that an employer can provide without triggering BIK (Benefit In Kind) income tax for the employee. The HMRC test is usually "the benefit cannot reasonably be converted to cash" plus a specific statutory exemption.

Trivial benefits: £50 cap. Any benefit costing under £50 (per occurrence) is exempt from tax and NI as long as it is not cash or a cash voucher, not a reward for performance, and not contractually owed. Examples: a £40 birthday gift hamper, a £30 store voucher at Christmas, a £45 bunch of flowers after a difficult project. Capped at £300 per year for directors of close companies (i.e. you cannot give yourself six £50 benefits every month). See trivial benefits £50 explainer for the worked rules and director-specific cap.

Workplace nursery. Childcare provided on site by the employer (or on premises the employer manages jointly with other employers) is 100% exempt from BIK, with no upper cap. The exemption survived the closure of Childcare Vouchers and Employer-Supported Childcare to new entrants in October 2018 and is the only fully-exempt childcare benefit still available to higher-rate parents. Worth tens of thousands per year for an employee paying central-London nursery rates.

Employer pension contributions. The employer's contribution to your pension is fully exempt from your Income Tax and from your NI, and is also a Corporation Tax deductible expense for the employer. This asymmetric treatment is what makes salary sacrifice into pension so efficient - the foregone salary moves from "fully taxed and NI'd" into "fully exempt for both sides".

Cycle-to-Work scheme: £1,000 effective cap. Salary sacrifice arrangement where the employer buys a bike (and accessories) and loans it to the employee. The foregone salary is exempt from Income Tax and NI; the bike is exempt from BIK provided the employee uses it primarily for commuting. Most schemes operate through Cyclescheme, Halfords Cycle2Work or Green Commute Initiative under a £1,000 consumer credit licence (uncapped under the FCA's higher group consumer credit licence, but most employers stick with the £1,000 limit). Effective cost to a higher-rate payer is roughly 58% of the bike's retail price after tax/NI savings. See cycle to work scheme for the mechanics.

EV salary sacrifice: ultra-low BIK. Sacrificing salary in exchange for a fully-electric company car costs much less than the equivalent personal lease, because the BIK rate on EVs is just 3% in 2026/27 (rising 1 percentage point per year to 9% by 2029/30). Compare with a petrol/diesel car at 25%+. A higher-rate employee leasing a £45k EV pays roughly £40-60/month of personal BIK tax instead of £400+ on a personal lease, while saving the full Income Tax + NI on the sacrificed salary. The structural saving is large enough that EV salary sacrifice has become the single most popular employer-provided benefit since 2022. See EV salary sacrifice for the full mathematics by BIK rate and lease term.

Other exempt benefits. Employer-provided mobile phone (one per employee, no cap); annual party up to £150 per head total across all events; long-service awards over 20 years (up to £50 per year of service); health screening (one per year); eye tests for VDU users and prescription glasses solely for VDU use; relocation expenses up to £8,000; counselling and welfare services; Christmas/Diwali/Eid party (within the £150 per head cap). All exempt from BIK by specific statutory provisions in ITEPA 2003.

14. Capital Gains Tax reliefs

CGT is charged on the gain (sale price minus base cost and allowable expenses), not the gross proceeds. Several reliefs reduce or eliminate the gain before tax is applied.

Annual Exempt Amount: £3,000. The tax-free slice of gains each year, applied automatically. Fell from £12,300 (2022/23) to £6,000 (2023/24) to £3,000 (2024/25 onwards). Cannot be carried forward - use it or lose it. Spouses each get a separate £3,000, so a family pair can crystallise £6,000 of gains tax-free per year through joint planning.

Private Residence Relief (PRR). Full exemption from CGT on the gain from selling your only or main residence. The most generous tax relief in the UK system - a household with a £400,000 gain on their main home pays £0 of CGT versus £80k-£96k on an equivalent buy-to-let gain. Conditions: the property must have been your only or main residence throughout ownership, with narrow exceptions for the final 9 months of ownership after moving out, and for periods of job-related absence up to 4 years.

Letting Relief. Reformed from April 2020: now only available where the owner is in shared occupancy with the tenant (i.e. lodger arrangements), capped at £40k and the lower of the PRR gain or the let gain. The pre-2020 "letting your former main home" version, which was widely used, has been abolished. For most former landlord-occupiers selling after 2020 this is no longer a meaningful relief.

Business Asset Disposal Relief (BADR). Formerly Entrepreneurs' Relief. Gives a reduced CGT rate on the first £1m of lifetime qualifying business disposals: 14% from 6 April 2025, rising to 18% from 6 April 2026 per Autumn Statement 2024. Qualifying disposals include: sale of all or part of a sole trade or partnership held 2+ years; sale of 5%+ shares in your personal trading company where you are an officer or employee for 24 months; sale of assets used in the business that has ceased trading. The lifetime cap is cumulative across all disposals, not per disposal.

Investors' Relief. Sister relief to BADR for external investors who held shares 3+ years in an unlisted trading company without being an officer or employee. Same reduced rates as BADR. Lifetime cap was £10m until the Autumn Statement 2024 cut it to £1m.

Holdover Relief. Lets you gift business assets (or assets into a trust) without crystallising the gain - the gain is "held over" into the recipient's base cost. Useful for intergenerational transfer of family business shares: dad transfers his trading company shares to his daughter, the £500k gain is parked in her base cost, and CGT only crystallises when she eventually sells. Combined with the 2-year BPR for IHT, a well-structured transfer can move significant business value across generations with deferred CGT and zero IHT.

Rollover Relief. Sale of one business asset and reinvestment of the proceeds into a new qualifying business asset within a 3-year window defers the gain into the new asset's base cost. Used for property portfolio reshuffles within trading businesses (e.g. moving from one office building to another).

15. Inheritance Tax reliefs

IHT charges 40% on the part of an estate above £325,000. Several reliefs and exemptions reduce or eliminate the bill.

Nil Rate Band (NRB): £325,000. The base slice of the estate that is taxed at 0%. Frozen since 2009. The Autumn Statement 2024 extended the freeze through April 2030.

Residence Nil Rate Band (RNRB): £175,000. An additional 0% band when a main residence (or its sale proceeds) passes to direct descendants - children, grandchildren, stepchildren, adopted or fostered children. Frozen since 2020 through April 2030. Tapers down for estates over £2m at £1 lost per £2 over, hitting zero at £2.35m. Combined NRB + RNRB = £500k per individual, £1m per married couple (because both NRB and RNRB are transferable to a surviving spouse).

Spouse / civil partner exemption: 100%. Transfers between spouses (during life or at death) are fully exempt from IHT, regardless of size. The estate of the first to die can transfer any unused NRB and RNRB to the survivor's estate (the "transferable nil rate band" rules), which is why most couples can shelter £1m before IHT applies.

Charity exemption: 100%. Bequests to registered charities are fully exempt. And if you leave 10%+ of the net estate (estate after NRB) to charity, the IHT rate on the rest of the estate drops from 40% to 36%. Worked example: £1m estate above NRB. Standard IHT = £400k. If you leave £100k (10%) to charity instead, taxable = £900k at 36% = £324k. Total to family = £576k vs £600k - the charity gets £100k and the family gives up only £24k. The reduced rate is a powerful nudge to make a meaningful charitable bequest once an estate is clearly IHT-paying.

Business Property Relief (BPR). 100% relief on unlisted trading company shares and unincorporated trading businesses held 2+ years. 50% relief on certain business assets and on controlling holdings in listed trading companies. Major changes from April 2026 per Autumn Statement 2024: BPR is being capped at a combined £1m allowance shared with Agricultural Property Relief, and AIM-listed shares drop from 100% BPR to 50%. A significant tightening for estates with large trading business or AIM portfolios.

Agricultural Property Relief (APR). 100% relief on working farmland and farmhouses occupied for agriculture 2+ years (7 if let). Same April 2026 cap as BPR (£1m combined). The change ignited the November 2024 "tractor tax" protests by farming groups concerned that modest family farms could now face six-figure IHT bills.

Annual gift exemption: £3,000. Gifts up to £3,000 in any tax year are immediately exempt from IHT, with one year's unused allowance carryable forward. Plus a £250 small-gift exemption per recipient per year (you can give £250 to any number of different people). Plus gifts in consideration of marriage (£5,000 from a parent, £2,500 from a grandparent, £1,000 from anyone else). Plus regular gifts out of "normal income" if they do not reduce your standard of living - a useful but documentation-heavy route for grandparents helping with school fees out of pension drawdown income.

Seven-year taper. Gifts above the annual exemption become Potentially Exempt Transfers (PETs) that are fully outside the estate after 7 years from the date of gift. Die within 7 years and the gift is added back into the estate, with the IHT rate tapering down: 100% in years 0-3, 80% in year 4, 60% in year 5, 40% in year 6, 20% in year 7, 0% from year 7+1 day. The taper applies to the tax due, not the gift itself - so PETs that fall within the NRB still consume the NRB even if death is within 7 years.

From April 2027: defined contribution pensions enter the IHT net. A material change announced at the Autumn Statement 2024. Currently DC pensions sit outside the estate and pass to nominated beneficiaries free of IHT (with a separate income tax test). From April 2027 unused DC pension funds will be included in the estate for IHT purposes - significantly increasing potential IHT bills for retirees with large SIPP pots. The two-year window between announcement and effective date triggered a wave of pension drawdown and gifting activity that estate-planning advisers are still working through.

16. Frequently asked questions

What is the difference between an allowance and a tax relief?

An allowance is a slice of income (or gains) that is tax-free at source - the Personal Allowance, ISA allowance, CGT annual exempt amount, dividend allowance and savings allowance all fit this pattern, with no claim required. A tax relief is a reduction in your tax bill that you (or your provider) must claim, usually because the underlying spending or investment qualifies for special treatment. Pension contributions, Gift Aid, EIS, SEIS, mileage and capital allowances are all reliefs - you have to either tick a box on Self Assessment or have your pension scheme administrator claim it for you. A deduction is a third concept: an amount subtracted from gross income before tax is computed (e.g. employee pension via Net Pay arrangement) - economically identical to relief but mechanically simpler because nothing is claimed back.

What is the Personal Allowance for 2026/27?

The standard Personal Allowance is £12,570 for 2026/27, frozen through 2027-28 per the Autumn Statement 2022 fiscal policy. It is the slice of taxable income you can earn before paying any Income Tax. Above £100,000 of adjusted net income the allowance tapers at £1 lost for every £2 of income, hitting zero at £125,140 - this is what creates the 60% effective marginal rate trap. Marriage Allowance can add £1,260 of transferred allowance on top, and Blind Person's Allowance adds £3,250 for registered blind taxpayers.

Can I claim higher-rate pension tax relief automatically?

It depends entirely on the contribution method. Net Pay arrangement (most older occupational schemes) and Salary Sacrifice both give higher-rate relief automatically because the contribution is taken from gross pay before PAYE is calculated. Relief at Source (RAS) - the default for personal pensions, SIPPs and most modern workplace schemes - only gives 20% basic-rate relief automatically. Higher-rate (40%) and additional-rate (45%) taxpayers using a RAS scheme must claim the extra 20% or 25% back through Self Assessment or by writing to HMRC. An estimated £1.3 billion of higher-rate pension relief goes unclaimed each year because RAS members assume the full relief has been applied at source.

Do I need to claim EIS relief in the year of investment?

You claim EIS income tax relief on the Self Assessment return for the tax year in which the EIS shares were issued, but you have up to five years from 31 January after the tax year to make the claim - so there is a long window if you miss the immediate return. You can also elect to carry back the relief to the prior tax year (useful if you had a higher tax bill last year). The carry-back is made within the same SA return: complete page 2 of the EIS3 certificate from the company, then enter the figures on the "Additional information" pages SA101 of the SA100 return. SEIS and VCT follow the same five-year claim window.

Does Gift Aid affect my tax code?

Not directly. Gift Aid is a relief claimed at year-end either by the charity (the 25% basic-rate gross-up) or by you via Self Assessment (the higher-rate top-up of 20% or 25%). HMRC does sometimes adjust higher-rate taxpayers' codes mid-year to give the relief through PAYE rather than waiting for the SA refund, but this is opt-in and only applied when you contact HMRC with an estimate of your charitable giving. Worth doing if your giving is regular and you would prefer monthly cash flow over an annual lump sum refund. The charity's reclaim does not interact with your code at all - that is a separate transaction between HMRC and the charity.

Can I carry forward unused EIS relief?

EIS income tax relief itself cannot be carried forward to a future year - it is use-it-or-lose-it in the tax year of investment (with the carry-back option to the prior year). However, EIS loss relief on a failed EIS company can be set against either income or capital gains in the year of loss, with the unused balance carried forward against future gains indefinitely if you elect for CGT loss treatment. CGT deferral relief (rolling a prior gain into EIS shares) defers the gain rather than eliminating it - the deferred gain crystallises when you sell the EIS shares, but can be deferred again into a further EIS investment.

Is Marriage Allowance refundable retroactively?

Yes. Marriage Allowance can be backdated up to four tax years, so a successful 2026/27 claim can also unlock refunds for 2022/23, 2023/24, 2024/25 and 2025/26 if you were married and met the eligibility conditions in each of those years. At £252 per year the maximum backdated refund is around £1,260. The non-earning (lower-earning) spouse makes the claim at gov.uk/marriage-allowance; HMRC issues refunds for prior years as a cheque or BACS payment and adjusts the current year through both spouses' tax codes (M and N suffix codes). Eligibility requires one spouse earning below the Personal Allowance and the other being a basic-rate taxpayer (not higher or additional rate).

What is the Annual Allowance and how does the taper work?

The pension Annual Allowance (AA) is £60,000 in 2026/27 - the cap on combined employee and employer pension contributions across all your pensions in a tax year that still attract tax relief. Excess contributions trigger an Annual Allowance charge at your marginal Income Tax rate. The Tapered Annual Allowance reduces this £60,000 by £1 for every £2 of "adjusted income" above £260,000, to a floor of £10,000 once adjusted income exceeds £360,000. Adjusted income includes salary, bonus, BIK and employer pension contributions - so high earners with generous employer pensions can hit the taper earlier than the £260k headline suggests. Unused AA from the prior three tax years can be carried forward if you were a pension scheme member in those years.

How does Section 24 mortgage interest restriction work for landlords?

Since April 2020, individual landlords renting out residential property can no longer deduct mortgage interest as an expense against rental income. Instead, HMRC gives a tax credit at the basic rate (20%) on the interest paid. Effect: a higher-rate landlord paying £10,000 of interest used to save £4,000 of tax (£10k deduction at 40%) but now only saves £2,000 (£10k credit at 20%). The change does not apply to limited company landlords (still fully deductible against corporation tax), commercial property, or furnished holiday lets (rules tightening from April 2025). For high-leverage portfolios in the higher tax band, Section 24 has tipped many landlords into incorporating or selling - HMRC reports a 17% drop in private landlord numbers between 2017 and 2024.

What are the CGT reliefs for selling a business?

Two big reliefs for entrepreneurs and business owners. Business Asset Disposal Relief (BADR, formerly Entrepreneurs' Relief) gives a reduced CGT rate of 14% from 6 April 2025 (rising to 18% from 6 April 2026) on the first £1m of lifetime qualifying gains from disposing of all or part of a trading business or shares in your personal trading company (5%+ holding, employee or officer for 24 months). Investors' Relief gives the same reduced rates on a separate £1m lifetime cap, cut from £10m at the Autumn Statement 2024, for external investors in unlisted trading companies. Both reliefs sit on top of the £3,000 Annual Exempt Amount. Holdover Relief lets you gift business assets to family members and defer the gain into the recipient's base cost.

What inheritance tax reliefs are available?

IHT charges 40% on the estate above the Nil Rate Band (£325,000 frozen to 2030) plus a £175,000 Residence Nil Rate Band when a main home passes to direct descendants. Key reliefs that reduce or eliminate the charge: spouse and civil partner transfers are 100% exempt; charity bequests are 100% exempt and trigger a reduced 36% rate on the rest of the estate if you leave 10%+ to charity; Business Property Relief gives 100% relief on unquoted trading company shares held 2+ years (50% on AIM shares from April 2026 per Autumn Statement 2024); Agricultural Property Relief gives 100% on working farmland (capped at £1m combined APR+BPR from April 2026). The annual gift exemption is £3,000 (carry forward one year) plus £250 small-gift exemption per recipient and the seven-year taper on potentially exempt transfers.

Are professional subscriptions and tools tax-deductible?

Yes, if the body or item appears on HMRC's approved lists. Professional subscriptions to bodies on HMRC's "List 3" (around 1,300 approved bodies covering chartered accountants, solicitors, architects, doctors, nurses, engineers, etc.) are deductible against employment income - typical claims run £100-500 per year. Annual subscriptions to non-approved bodies are not deductible. Tools and protective clothing for trades (mechanics, plumbers, electricians, nurses, hairdressers) qualify either at HMRC's flat rate amounts (£60-185 per year by trade) or at actual cost with receipts. Uniforms and laundering also attract flat-rate relief. Submit via a P87 form or through Self Assessment if you already file one.
