UK Tax-Free Allowances Stack: 2026/27

UK Tax-Free Allowances Stack 2026/27: PA, PSA, Dividend, CGT, ISA Combined

Q: What is the total UK tax-free income I can earn in 2026/27?

For a basic-rate taxpayer with diverse income sources , the stacked tax-free amount can exceed £30,000/year. Worked combination : £12,570 Personal Allowance + £5,000 Starting Rate for Savings (if other income < £17,570) + £1,000 Personal Savings Allowance + £500 Dividend Allowance + £1,000 Trading Allowance + £1,000 Property Allowance + £7,500 Rent-a-Room Relief = potentially £28,570 of tax-free income. NOT additive in all combinations : Trading Allowance + Property Allowance can't apply to same income. Starting Rate for Savings tapers as other income rises. Realistic max for typical worker : £12,570 PA + £1,000 PSA + £500 Dividend + £3,000 CGT = ~£17k of standard tax-free amounts. For pension contributors : add £60,000 Annual Allowance (pre-tax money into pension wrapper) - not strictly "tax-free income" but tax-deferred until drawdown. For high earners : most allowances taper or have cliffs. PA fully gone at £125,140. PSA drops to £500 at higher-rate, £0 at additional-rate. Effective tax-free band narrows dramatically. Couples can double most allowances by income-splitting where legitimate.

Q: How do allowances interact - which apply to which income type?

Income Tax stack order (Section 16 ITA 2007): (1) earned income (salary, self-employed, rental, pension) uses Personal Allowance first; (2) savings income uses any remaining PA + PSA + SRS; (3) dividend income uses any remaining PA + Dividend Allowance. Worked example - £45k salary + £5k savings + £10k dividends : PA covers £12,570 of salary. £32,430 salary in basic-rate band. £5k savings → £500 PSA (higher-rate) + £4,500 at 20% = £900 IT. £10k dividends → £500 Dividend Allowance + £9,500 at 8.75% = £831 IT. CGT independent : gains don't stack into IT band - they have separate £3k AEA + 18%/24% rates. NI separate : National Insurance doesn't use any allowances - based on earnings only above LEL/PT. Capital + lifetime tax-free : ISA + pension wrappers protect future income from BOTH IT and CGT. £20k/year of ISA over 30 years = £600k capital that throws off tax-free income forever. Bands shared between IT + CGT : basic-rate band ceiling £50,270 applies to IT taxable income. CGT 18% applies if gain falls below remaining ceiling; 24% above. So salary + gains compete for the same band space.

Q: What changes to allowances are scheduled for 2026/27 and beyond?

Frozen allowances 2026/27 (continuing freeze) : Personal Allowance £12,570 (frozen 2021-2030, extended Autumn Budget 2024), higher-rate threshold £50,270 (frozen 2021-2030), additional-rate threshold £125,140 (frozen since 2010), £100k taper start (frozen since 2010), Personal Savings Allowance, Dividend Allowance £500, CGT AEA £3,000, ISA £20,000 (frozen since 2017), Pension Annual Allowance £60,000 (since 2023). April 2026 changes : BPR + APR 100% capped at £1m per individual (Autumn Budget 2024). EV company car BIK rate 3%. NMW £12.71/hr (rising). April 2027 changes : pension included in IHT estate (Finance Act 2025). EV BIK 4%. April 2028 changes : MTD ITSA extended to >£20k. Pre-2006 NI gap backfill deadline. EV BIK 5%. Cumulative fiscal drag : PA frozen since 2021 + inflation 25%+ over freeze period = real-terms PA reduction equivalent to ~£3,000. Pushes more workers into tax + higher bands. £100k threshold frozen since 2010 = equivalent to £175,000 in 2010 money - dramatically more people now caught by 60% effective marginal rate. Government strategy: avoid politically-visible rate rises while collecting more revenue via inflation.

Q: Can I claim Trading + Property + Rent-a-Room allowances together?

Yes - but to different income streams . Each is per-income-type. Trading Allowance £1,000 : covers gross trading income (side hustle, freelance). All-or-nothing election - either use £1k allowance + ignore expenses, OR ignore allowance + deduct actual expenses. Best when actual expenses are low ( Property Allowance £1,000 : same mechanic for rental income. Best for low-mortgage / low-maintenance rental properties. Rent-a-Room Relief £7,500 : only applies to renting rooms in MAIN RESIDENCE (not separate properties). Tax-free if gross rent below £7,500; if above, can deduct £7,500 from gross. Combined max possible : £1k trading + £1k property + £7.5k Rent-a-Room = £9,500/year tax-free income from these three. Add ISA wrapper for any income earned via ISA-held investments = tax-free + NI-free indefinitely. Common mistake : people claim BOTH £1k Property Allowance + Section 24 mortgage interest restriction calc. Cannot have both. Must elect Property Allowance OR full expenses method. £1k threshold check : if gross income exceeds £1k, the election is to either claim full £1k allowance (no expenses) OR claim actual expenses (no allowance). The lower of the two methods wins.

Q: How does Personal Savings Allowance work and who gets the most?

Personal Savings Allowance (PSA) = tax-free band for savings interest only. Section 12A ITA 2007. Amount by tax band : basic-rate £1,000, higher-rate £500, additional-rate £0. Applied AFTER all other income. Starting Rate for Savings (SRS) : separate £5,000 band of 0% on savings if other income is below £17,570. Tapers £1-for-£1 as other income rises. Worked example - low-income retiree with £14k State Pension + £8k savings interest : PA covers £12,570 of pension. Remaining £1,430 pension at 20% = £286. Savings: £3,570 in remaining SRS band (£17,570 - £14k other) at 0% + £4,430 in PSA + standard 20% bands. Effectively most savings tax-free. Best case savers : pensioner with modest pension income gets ~£10,000+ of tax-free savings. Common scenario for retirees. Worst case savers : additional-rate taxpayer gets ZERO PSA - £1 of interest = 45p tax. Strategic PSA optimisation : high earners move savings into ISA (£20k/year free of tax) or premium bonds (NS&I tax-free prizes). Basic-rate workers should hold £30k+ in non-ISA savings to fill PSA without hitting tax band.

Q: How does the Dividend Allowance work and is it falling?

Dividend Allowance £500 (2026/27, frozen from 2024/25). Trajectory: £5,000 (2016/17), £2,000 (2018/19-2022/23), £1,000 (2023/24), £500 (2024/25+). 90% reduction in 6 years. Mechanics : £500 of dividends tax-free regardless of tax band. Above £500: 8.75% basic, 33.75% higher, 39.35% additional. SA registration threshold : gross dividend income above £10,000 (was £2,000 pre-April 2024) triggers SA filing. Many small investors below £10k can rely on HMRC P800 reconciliation. Limited company directors : most personal dividend planning structured around the £500 allowance + £37,200 basic-rate band ÷ 8.75% rate = optimal £37,700 dividend extraction within basic-rate band. Worked example - £80k salary director + £25k dividends : PA used by salary. Salary in higher-rate band. £500 dividend allowance + £24,500 dividend taxed at 33.75% = £8,269. Effective rate ~33%. Future direction : government has not announced further dividend allowance cuts but frozen rates against inflation means real-terms erosion. Watch budget statements for further reductions.

Q: How do I use the £3,000 CGT Annual Exempt Amount?

CGT AEA £3,000 : tax-free portion of net capital gains each tax year. Section 3 TCGA 1992. Use it or lose it : no carry-forward of unused AEA to next year. Mechanics : aggregate all gains - losses in tax year; subtract £3k AEA; apply rates 18% basic / 24% higher-rate. Spousal pooling : each spouse has own £3k AEA. Transfer asset to spouse before disposal (no-gain-no-loss under Section 58 TCGA 1992) to use both AEAs = £6k tax-free per year. Cross-tax-year timing : large disposal can be split across tax years. Disposal on 5 April 2027 vs 6 April 2027 uses different years' AEAs. Each year £3k tax-free. Bed and ISA + bed and SIPP : sell non-tax-advantaged holding to crystallise gain (within AEA = no tax), buy back in ISA/SIPP wrapper = future growth tax-free. 30-day bed and breakfast rule blocks repurchase outside wrapper but allows wrapper rebuy. Loss harvesting : realise losses in same year as gains to offset £-for-£ before applying AEA. Carry-forward losses indefinitely. Historical context : £12,300 in 2022/23 → £6,000 in 2023/24 → £3,000 from 2024/25. 75% cut in 2 years - significant tax planning impact for share/crypto holders.

Q: What is the ISA allowance for 2026/27 and how to maximise?

ISA Allowance £20,000 total across all ISA types (Cash, Stocks & Shares, Innovative Finance, Lifetime ISA). Frozen since 2017/18. Within £20k : LISA sub-cap £4,000 for ages 18-39 (25% government bonus £1k/yr); IFISA no sub-cap (peer-to-peer lending). Junior ISA £9,000 : separate, per-child under 18. NOT counted toward parent's £20k. Optimal strategy : max £20k each year. Compounding tax-free wrapper over 30+ years = several hundred thousand pounds of tax-free growth potential. Mixing : split £20k freely across types in same tax year (e.g., £15k Cash ISA + £4k LISA + £1k S&S ISA). Transfers between providers : ISA-to-ISA transfers via NEW provider (never withdraw + redeposit yourself - that uses fresh allowance). Spousal ISA : each spouse has own £20k. Couple = £40k/year combined. Inheritance ISA (APS) : deceased spouse's ISA can transfer to surviving spouse at full value without losing tax wrapper. Section 38A ISA Regulations 1998. Flexible ISAs : allow withdrawals + re-deposits within same tax year without using fresh allowance. Increasingly common feature. Cash ISA rates : easy-access ~3-4% currently. Fixed-rate 1-5 years for higher rates. S&S ISA : long-term growth typically beats Cash ISA over 10+ years.

Q: What is Marriage Allowance and when does it help?

Marriage Allowance (MA) : transfers £1,260 of Personal Allowance from spouse / civil partner earning below £12,570 to higher-earning spouse who must be BASIC-RATE only. £252 annual saving (20% × £1,260). Eligibility : married or civil partners, transferor income < £12,570, recipient income £12,571 - £50,270 (or Scottish basic-rate band). Both born after 6 April 1935. Backdating : claim up to 4 years backdated = potential £1,260 lump sum + £252/year ongoing. Cancel triggers : recipient becomes higher-rate (clawback), divorce, transferor earns above £13,830 (negative return), death. Scotland : rate varies by recipient's band - £239-£264 saving depending on starter / basic / intermediate. NOT for higher-rate couples : recipient must be basic-rate only. Higher-rate earners need different strategies (Married Couple's Allowance for pre-1935 - very few qualify, family investment companies, etc.). Apply : gov.uk/apply-marriage-allowance - lower earner applies. Free + simple. NEVER pay third-party services 30-50% commission for what's a 10-minute form. Backdated claim worked example : couple eligible since 2022/23 but never claimed. First application in 2026/27 backdates 4 years (2022/23, 2023/24, 2024/25, 2025/26) + current year = £1,260 lump sum + £252 ongoing.

Q: How does the £100k taper interact with all allowances?

£100k Adjusted Net Income (ANI) cliff triggers multiple allowance losses simultaneously. Personal Allowance : tapers £1 for every £2 above £100k, fully gone at £125,140. Lost PA × 40% = ~£5,028 extra tax. Personal Savings Allowance : drops from £1,000 (basic-rate) to £500 (higher-rate) when total income enters higher band. Lost PSA × marginal rate = £200 extra tax. Tax-Free Childcare £100k cliff : HARD cliff (no taper). Earning £100,000.01 = lose entire family TFC entitlement (up to £4k/child/year). HICBC threshold : 1% per £200 above £60k, fully gone by £80k. Already-resolved before £100k for most but Child Benefit recipients. 30-hours funded childcare : same £100k cliff per parent for England's 30-hours-extended programme. Pension AA taper : at adjusted income £260k+, AA tapers from £60k to £10k floor. Combined cliff cost : family with 2 nursery-aged children + Child Benefit + earner approaching £100k faces ~£10,000+ in lost allowances and benefits crossing the threshold. Mitigation : pension contributions reduce ANI £-for-£ - one tool fixes most cliffs simultaneously. See our 60% marginal rate escape guide for detailed strategies.

Frequently asked questions

What is the total UK tax-free income I can earn in 2026/27?

For a basic-rate taxpayer with diverse income sources, the stacked tax-free amount can exceed £30,000/year. Worked combination: £12,570 Personal Allowance + £5,000 Starting Rate for Savings (if other income < £17,570) + £1,000 Personal Savings Allowance + £500 Dividend Allowance + £1,000 Trading Allowance + £1,000 Property Allowance + £7,500 Rent-a-Room Relief = potentially £28,570 of tax-free income. NOT additive in all combinations: Trading Allowance + Property Allowance can't apply to same income. Starting Rate for Savings tapers as other income rises. Realistic max for typical worker: £12,570 PA + £1,000 PSA + £500 Dividend + £3,000 CGT = ~£17k of standard tax-free amounts. For pension contributors: add £60,000 Annual Allowance (pre-tax money into pension wrapper) - not strictly "tax-free income" but tax-deferred until drawdown. For high earners: most allowances taper or have cliffs. PA fully gone at £125,140. PSA drops to £500 at higher-rate, £0 at additional-rate. Effective tax-free band narrows dramatically. Couples can double most allowances by income-splitting where legitimate.

How do allowances interact - which apply to which income type?

Income Tax stack order (Section 16 ITA 2007): (1) earned income (salary, self-employed, rental, pension) uses Personal Allowance first; (2) savings income uses any remaining PA + PSA + SRS; (3) dividend income uses any remaining PA + Dividend Allowance. Worked example - £45k salary + £5k savings + £10k dividends: PA covers £12,570 of salary. £32,430 salary in basic-rate band. £5k savings → £500 PSA (higher-rate) + £4,500 at 20% = £900 IT. £10k dividends → £500 Dividend Allowance + £9,500 at 8.75% = £831 IT. CGT independent: gains don't stack into IT band - they have separate £3k AEA + 18%/24% rates. NI separate: National Insurance doesn't use any allowances - based on earnings only above LEL/PT. Capital + lifetime tax-free: ISA + pension wrappers protect future income from BOTH IT and CGT. £20k/year of ISA over 30 years = £600k capital that throws off tax-free income forever. Bands shared between IT + CGT: basic-rate band ceiling £50,270 applies to IT taxable income. CGT 18% applies if gain falls below remaining ceiling; 24% above. So salary + gains compete for the same band space.

What changes to allowances are scheduled for 2026/27 and beyond?

Frozen allowances 2026/27 (continuing freeze): Personal Allowance £12,570 (frozen 2021-2030, extended Autumn Budget 2024), higher-rate threshold £50,270 (frozen 2021-2030), additional-rate threshold £125,140 (frozen since 2010), £100k taper start (frozen since 2010), Personal Savings Allowance, Dividend Allowance £500, CGT AEA £3,000, ISA £20,000 (frozen since 2017), Pension Annual Allowance £60,000 (since 2023). April 2026 changes: BPR + APR 100% capped at £1m per individual (Autumn Budget 2024). EV company car BIK rate 3%. NMW £12.71/hr (rising). April 2027 changes: pension included in IHT estate (Finance Act 2025). EV BIK 4%. April 2028 changes: MTD ITSA extended to >£20k. Pre-2006 NI gap backfill deadline. EV BIK 5%. Cumulative fiscal drag: PA frozen since 2021 + inflation 25%+ over freeze period = real-terms PA reduction equivalent to ~£3,000. Pushes more workers into tax + higher bands. £100k threshold frozen since 2010 = equivalent to £175,000 in 2010 money - dramatically more people now caught by 60% effective marginal rate. Government strategy: avoid politically-visible rate rises while collecting more revenue via inflation.

Can I claim Trading + Property + Rent-a-Room allowances together?

Yes - but to different income streams. Each is per-income-type. Trading Allowance £1,000: covers gross trading income (side hustle, freelance). All-or-nothing election - either use £1k allowance + ignore expenses, OR ignore allowance + deduct actual expenses. Best when actual expenses are low (<£1k). Property Allowance £1,000: same mechanic for rental income. Best for low-mortgage / low-maintenance rental properties. Rent-a-Room Relief £7,500: only applies to renting rooms in MAIN RESIDENCE (not separate properties). Tax-free if gross rent below £7,500; if above, can deduct £7,500 from gross. Combined max possible: £1k trading + £1k property + £7.5k Rent-a-Room = £9,500/year tax-free income from these three. Add ISA wrapper for any income earned via ISA-held investments = tax-free + NI-free indefinitely. Common mistake: people claim BOTH £1k Property Allowance + Section 24 mortgage interest restriction calc. Cannot have both. Must elect Property Allowance OR full expenses method. £1k threshold check: if gross income exceeds £1k, the election is to either claim full £1k allowance (no expenses) OR claim actual expenses (no allowance). The lower of the two methods wins.

How does Personal Savings Allowance work and who gets the most?

Personal Savings Allowance (PSA) = tax-free band for savings interest only. Section 12A ITA 2007. Amount by tax band: basic-rate £1,000, higher-rate £500, additional-rate £0. Applied AFTER all other income. Starting Rate for Savings (SRS): separate £5,000 band of 0% on savings if other income is below £17,570. Tapers £1-for-£1 as other income rises. Worked example - low-income retiree with £14k State Pension + £8k savings interest: PA covers £12,570 of pension. Remaining £1,430 pension at 20% = £286. Savings: £3,570 in remaining SRS band (£17,570 - £14k other) at 0% + £4,430 in PSA + standard 20% bands. Effectively most savings tax-free. Best case savers: pensioner with modest pension income gets ~£10,000+ of tax-free savings. Common scenario for retirees. Worst case savers: additional-rate taxpayer gets ZERO PSA - £1 of interest = 45p tax. Strategic PSA optimisation: high earners move savings into ISA (£20k/year free of tax) or premium bonds (NS&I tax-free prizes). Basic-rate workers should hold £30k+ in non-ISA savings to fill PSA without hitting tax band.

How does the Dividend Allowance work and is it falling?

Dividend Allowance £500 (2026/27, frozen from 2024/25). Trajectory: £5,000 (2016/17), £2,000 (2018/19-2022/23), £1,000 (2023/24), £500 (2024/25+). 90% reduction in 6 years. Mechanics: £500 of dividends tax-free regardless of tax band. Above £500: 8.75% basic, 33.75% higher, 39.35% additional. SA registration threshold: gross dividend income above £10,000 (was £2,000 pre-April 2024) triggers SA filing. Many small investors below £10k can rely on HMRC P800 reconciliation. Limited company directors: most personal dividend planning structured around the £500 allowance + £37,200 basic-rate band ÷ 8.75% rate = optimal £37,700 dividend extraction within basic-rate band. Worked example - £80k salary director + £25k dividends: PA used by salary. Salary in higher-rate band. £500 dividend allowance + £24,500 dividend taxed at 33.75% = £8,269. Effective rate ~33%. Future direction: government has not announced further dividend allowance cuts but frozen rates against inflation means real-terms erosion. Watch budget statements for further reductions.

How do I use the £3,000 CGT Annual Exempt Amount?

CGT AEA £3,000: tax-free portion of net capital gains each tax year. Section 3 TCGA 1992. Use it or lose it: no carry-forward of unused AEA to next year. Mechanics: aggregate all gains - losses in tax year; subtract £3k AEA; apply rates 18% basic / 24% higher-rate. Spousal pooling: each spouse has own £3k AEA. Transfer asset to spouse before disposal (no-gain-no-loss under Section 58 TCGA 1992) to use both AEAs = £6k tax-free per year. Cross-tax-year timing: large disposal can be split across tax years. Disposal on 5 April 2027 vs 6 April 2027 uses different years' AEAs. Each year £3k tax-free. Bed and ISA + bed and SIPP: sell non-tax-advantaged holding to crystallise gain (within AEA = no tax), buy back in ISA/SIPP wrapper = future growth tax-free. 30-day bed and breakfast rule blocks repurchase outside wrapper but allows wrapper rebuy. Loss harvesting: realise losses in same year as gains to offset £-for-£ before applying AEA. Carry-forward losses indefinitely. Historical context: £12,300 in 2022/23 → £6,000 in 2023/24 → £3,000 from 2024/25. 75% cut in 2 years - significant tax planning impact for share/crypto holders.

What is the ISA allowance for 2026/27 and how to maximise?

ISA Allowance £20,000 total across all ISA types (Cash, Stocks & Shares, Innovative Finance, Lifetime ISA). Frozen since 2017/18. Within £20k: LISA sub-cap £4,000 for ages 18-39 (25% government bonus £1k/yr); IFISA no sub-cap (peer-to-peer lending). Junior ISA £9,000: separate, per-child under 18. NOT counted toward parent's £20k. Optimal strategy: max £20k each year. Compounding tax-free wrapper over 30+ years = several hundred thousand pounds of tax-free growth potential. Mixing: split £20k freely across types in same tax year (e.g., £15k Cash ISA + £4k LISA + £1k S&S ISA). Transfers between providers: ISA-to-ISA transfers via NEW provider (never withdraw + redeposit yourself - that uses fresh allowance). Spousal ISA: each spouse has own £20k. Couple = £40k/year combined. Inheritance ISA (APS): deceased spouse's ISA can transfer to surviving spouse at full value without losing tax wrapper. Section 38A ISA Regulations 1998. Flexible ISAs: allow withdrawals + re-deposits within same tax year without using fresh allowance. Increasingly common feature. Cash ISA rates: easy-access ~3-4% currently. Fixed-rate 1-5 years for higher rates. S&S ISA: long-term growth typically beats Cash ISA over 10+ years.

What is Marriage Allowance and when does it help?

Marriage Allowance (MA): transfers £1,260 of Personal Allowance from spouse / civil partner earning below £12,570 to higher-earning spouse who must be BASIC-RATE only. £252 annual saving (20% × £1,260). Eligibility: married or civil partners, transferor income < £12,570, recipient income £12,571 - £50,270 (or Scottish basic-rate band). Both born after 6 April 1935. Backdating: claim up to 4 years backdated = potential £1,260 lump sum + £252/year ongoing. Cancel triggers: recipient becomes higher-rate (clawback), divorce, transferor earns above £13,830 (negative return), death. Scotland: rate varies by recipient's band - £239-£264 saving depending on starter / basic / intermediate. NOT for higher-rate couples: recipient must be basic-rate only. Higher-rate earners need different strategies (Married Couple's Allowance for pre-1935 - very few qualify, family investment companies, etc.). Apply: gov.uk/apply-marriage-allowance - lower earner applies. Free + simple. NEVER pay third-party services 30-50% commission for what's a 10-minute form. Backdated claim worked example: couple eligible since 2022/23 but never claimed. First application in 2026/27 backdates 4 years (2022/23, 2023/24, 2024/25, 2025/26) + current year = £1,260 lump sum + £252 ongoing.

How does the £100k taper interact with all allowances?

£100k Adjusted Net Income (ANI) cliff triggers multiple allowance losses simultaneously. Personal Allowance: tapers £1 for every £2 above £100k, fully gone at £125,140. Lost PA × 40% = ~£5,028 extra tax. Personal Savings Allowance: drops from £1,000 (basic-rate) to £500 (higher-rate) when total income enters higher band. Lost PSA × marginal rate = £200 extra tax. Tax-Free Childcare £100k cliff: HARD cliff (no taper). Earning £100,000.01 = lose entire family TFC entitlement (up to £4k/child/year). HICBC threshold: 1% per £200 above £60k, fully gone by £80k. Already-resolved before £100k for most but Child Benefit recipients. 30-hours funded childcare: same £100k cliff per parent for England's 30-hours-extended programme. Pension AA taper: at adjusted income £260k+, AA tapers from £60k to £10k floor. Combined cliff cost: family with 2 nursery-aged children + Child Benefit + earner approaching £100k faces ~£10,000+ in lost allowances and benefits crossing the threshold. Mitigation: pension contributions reduce ANI £-for-£ - one tool fixes most cliffs simultaneously. See our 60% marginal rate escape guide for detailed strategies.

What pension-related tax-free items should I know?

Pension Annual Allowance £60,000 (2026/27, since April 2023). Total contributions across all schemes. Carry-forward 3 unused years. Money Purchase AA £10,000: triggered by flexible drawdown beyond 25% PCLS. Tapered Annual Allowance: 1:2 taper for adjusted income £260,000-£360,000. Floor £10,000. Pension contribution tax relief: contributions to UK-registered pension scheme get IT relief at marginal rate. Plus NI saving if via salary sacrifice. Effective relief 20%-62% by band + scheme. Lump Sum Allowance (LSA) £268,275: lifetime maximum tax-free PCLS (25% pension commencement lump sum). LTA abolished April 2024 + replaced. Lump Sum and Death Benefit Allowance (LSDBA) £1,073,100: lifetime cap on tax-free death benefits to beneficiaries. Tax-free pension growth: all gains within pension wrapper grow tax-free. No CGT, no IT on dividends/interest within the wrapper. State Pension: £241.30/wk (New State Pension 2026/27) is TAXABLE income (counts toward PA + bands) but not subject to NI. Pension small pots: up to 3 personal pension pots under £10,000 each can be taken as fully tax-free lump sums (Section 166 FA 2004). Up to 30k tax-free combined.

Allowance stacking optimisation for a couple at £100k household income

Couple A + B with combined £100,000 household income (e.g., A £60k + B £40k). Both basic-rate: each gets full PA £12,570 = £25,140 IT-free; each PSA £1,000 = £2,000 PSA combined; each Dividend Allowance £500 = £1,000; each CGT AEA £3,000 = £6,000 combined; each ISA £20,000 = £40,000 tax-free wrapper space. Total annual tax-free capacity: £74,140 of recurring + investment allowances. Add specific allowances: Marriage Allowance £252 saving if one earner under PA; pension AA £60k each × 2 = £120,000 combined pension shelter; £6k spousal CGT pooling. Real-world household: most couples don't have £74k to allocate but stacking £20k ISA each + £60k pension each over 30 years = £4.8m of tax-sheltered wealth accumulation potential. Income smoothing: rebalance income between spouses where possible. Jointly-held property income default 50/50 unless Form 17 election. Dividend-paying shares can be transferred between spouses (no-gain-no-loss). Children: each child gets £9k JISA + own £12,570 PA + £1k PSA + £500 Dividend Allowance. Pension contribution £3,600 gross/year (no earnings needed). Family compound: 2 parents + 2 kids tax-free wrapper space = £100k+/year via ISA + JISA + pension. Hundreds of thousands tax-free over 18 years.
