Salary sacrifice pension: 2026/27
Salary Sacrifice Pension 2026/27: 23% NI Saving After April 2025
Salary sacrifice pension contributions in 2026/27: combined NI saving of 23% (8% employee + 15% employer) post-April-2025 vs 21.8% pre-April-2025, plus 20-40-45% income tax relief stacked on top. Worked tables at 5 salary points from £30k to £150k, NMW floor constraint, OpRA carve-outs (pension / EV / cycle / nursery still tax-and-NI-efficient), employer top-up patterns, bonus sacrifice strategy, £100k PA-taper zone optimisation.
What changed with the April 2025 NI rise
| Component | Pre-April-2025 | From April 2025 | Effect on sacrifice |
|---|---|---|---|

| Secondary Threshold | £9,100 | £5,000 | Wider NI base = bigger saving |
| Employee NI rate (main) | 8% | 8% | Unchanged |
| Income tax bands | 20/40/45% | 20/40/45% | Unchanged |
| Combined basic-rate saving | 41.8% | 43% | +1.2pp relative gain |
| Combined higher-rate saving | 55.8% | 57% | +1.2pp relative gain |
5 worked salary-sacrifice scenarios
Each row assumes the employer passes 100% of the employer NI saving through to your pension as a "salary sacrifice top-up". Some employers retain the NI saving; ask payroll directly.
| Salary band | Salary | Sacrifice | IT saved | EE NI saved | ER NI top-up | Pension in | Net cost | Boost rate |
|---|---|---|---|---|---|---|---|---|
| Basic-rate | £30,000 | £3,000 | £600 | £240 | £450 | £3,450 | £2,160 | +60% |
| Basic-rate (top) | £45,000 | £5,000 | £1,000 | £400 | £750 | £5,750 | £3,600 | +60% |
| Higher-rate | £65,000 | £8,000 | £3,200 | £160 | £1,200 | £9,200 | £4,640 | +98% |
| PA-taper zone | £100,000 | £10,000 | £4,000 | £200 | £1,500 | £11,500 | £5,800 | +98% |
| Additional-rate | £150,000 | £15,000 | £6,750 | £300 | £2,250 | £17,250 | £7,950 | +117% |
"Boost rate" = (pension contribution - your net-pay cost) / your net-pay cost. A 100% boost means £1 of net-pay cost buys £2 of pension contribution. Basic-rate sacrifice typically delivers 70-90% boost; higher-rate 130-170%; PA-taper zone (£100k-£125,140) 200%+.
NMW floor - the hard constraint
You cannot salary-sacrifice below the National Minimum Wage hourly rate (Section 18 NMW Act 1998). Rates effective April 2026:
| Band | Hourly rate | 37.5-hour week annual | Headroom from £30k |
|---|---|---|---|
| National Living Wage (21+) | £12.71 | £24,784 | £5,216 |
| 18-20 | £10.85 | £21,158 | £8,842 |
| 16-17 / Apprentice | £8.00 | £15,600 | £14,400 |
Pension contributions sacrificed to a workplace pension are NOT counted in the NMW calculation - they sit OUTSIDE the NMW pay. Employers running auto-enrolment via salary sacrifice typically default new joiners on or near NMW into a non-sacrifice "relief-at-source" route to avoid the floor problem.
OpRA - what salary sacrifice still works
Optional Remuneration Arrangements (OpRA) introduced April 2017 by Finance Act 2017 killed most "cheap benefit" salary sacrifice. Surviving routes:
- Pension contributions - workplace DC, SIPP, SSAS. Fully tax + NI efficient. The dominant remaining use case.
- Ultra-low-emission vehicles (sub-75g/km CO2, in practice electric or PHEV with 70+ mile electric range). Company car BIK 3% for FY26/27 on electric, rising slowly toward 9% by FY28/29. EV salary sacrifice still 30-40% net savings vs personal lease.
- Cycle to Work (up to £1,000 limit pre-2019, now uncapped via FCA-regulated providers). 32% saving for basic-rate, 42% for higher-rate.
- Workplace nurseries (employer-provided, not commercial vouchers). Tax-free under Section 318 ITEPA 2003.
- Death-in-service / income protection via the employer's group scheme - some sacrifice routes still work where the scheme is technically the employer's.
Killed by OpRA (no longer worth sacrificing for): petrol/diesel company car BIK, mobile phones, gym memberships, healthcare insurance, season ticket loans above £10k, accommodation, retail vouchers.
Frequently asked questions
How much can I save with salary sacrifice in 2026/27?
Depends on your tax band but the combined employee saving in 2026/27 is between 28% and 47% of the sacrificed amount, with an EXTRA 15% employer NI saving available that good employers pass through to your pension. Worked example for a basic-rate earner on £30,000 sacrificing £3,000 into pension: income tax saved £600 (20%), employee NI saved £240 (8%), employer NI saved £450 (15% on the £3,000 - now passed to your pension by progressive employers). Total benefit: £3,000 into pension + £450 employer top-up = £3,450 of pension contribution for a real-terms take-home cost of £2,160. Higher-rate earner on £65,000 sacrificing £8,000: £3,200 income tax + £160 NI + £1,200 employer NI = total £8,000 + £1,200 = £9,200 pension contribution for £4,640 net cost. The April 2025 employer NI rise to 15% (from 13.8%) made the employer-NI component noticeably larger.
What changed with salary sacrifice after April 2025?
Two changes amplified the salary-sacrifice benefit from April 2025 onwards. Employer NI rate: raised from 13.8% to 15% in the Autumn Budget 2024 (Finance Bill 2024-25). Secondary Threshold: cut from £9,100 to £5,000. Combined effect: nearly all employer-side NI is now charged at 15% on a much wider range of salaries. For salary sacrifice this means each £1 of sacrifice now saves the employer 15p of NI vs 13.8p before - a 9% relative increase in the employer-side benefit. Progressive employers pass this saving through to your pension as an "employer NI top-up" or "salary sacrifice rebate". The combined employee + employer saving on a basic-rate earner went from ~41.8% (20% IT + 8% EE NI + 13.8% ER NI) pre-April-2025 to ~43% (20% + 8% + 15%) from April 2025 onwards. Higher-rate earners went from ~55.8% to ~57% combined saving. Worth specifically asking your employer "do you pass through the employer NI saving on salary sacrifice?"
What is the National Minimum Wage floor for salary sacrifice?
You cannot salary-sacrifice below the National Minimum Wage floor for your hourly band (Section 18 NMW Act 1998). NMW rates effective April 2026: National Living Wage (21+) £12.71/hour, 18-20 rate £10.85/hour, 16-17 rate £8.00/hour, Apprentice rate £8.00/hour. For a full-time 37.5-hour-per-week NLW worker, annual gross is £12.71 × 37.5 × 52 = £24,784. So a £24,000 worker on NLW has only £-784 of headroom (none) - they cannot salary-sacrifice at all without falling below NMW. A £30,000 earner has £5,216 of NMW headroom — that's their maximum sacrifice. The NMW floor applies on a pay-reference-period basis (usually weekly or monthly), so part-month sacrifice arrangements need careful structuring. Pension contributions sacrificed to a workplace pension are NOT counted in the NMW calculation - they sit OUTSIDE the NMW pay. Employers running auto-enrolment via salary sacrifice typically default new joiners on or near NMW into a non-sacrifice "relief-at-source" route to avoid the floor problem.
What is the Optional Remuneration Arrangements (OpRA) rule?
OpRA (introduced April 2017 by Finance Act 2017 Schedule 2, codified as Section 69A-C ITEPA 2003) restricts the tax-and-NI advantage of swapping cash for benefits-in-kind. Under OpRA, if you sacrifice salary for a benefit, the taxable value of the benefit is the GREATER of: (a) the cash given up, or (b) the normal cash-equivalent of the benefit. This was designed to kill the cheap-BIK loophole - e.g. sacrificing £5,000 of salary for a £3,000 company car BIK. After OpRA, that £3,000 BIK is treated as £5,000 taxable income, removing the tax saving. BUT OpRA explicitly carves out: pensions, employer-provided childcare vouchers (legacy schemes), workplace nurseries, cycle-to-work schemes, ultra-low-emission cars (sub-75g/km CO2, effectively electric/hybrid). These remain fully tax-and-NI efficient. So salary sacrifice for PENSIONS, EV/cycle, nursery is unaffected by OpRA - which is why these are the main remaining salary-sacrifice products.
How does salary sacrifice affect my Annual Allowance?
Pension contributions via salary sacrifice count as EMPLOYER contributions, not personal contributions. This matters for the Annual Allowance £60,000 (Section 228 FA 2004) and the Money Purchase Annual Allowance (MPAA) £10,000. Annual Allowance: covers ALL contributions (employer + personal + sacrifice) regardless of route. £60,000 cap applies. MPAA: triggered if you have flexibly accessed any DC pension - drops your AA to £10,000 covering ALL contributions including salary sacrifice. Tapered AA: applies if your "adjusted income" exceeds £260,000 - tapered down £1 for every £2 above, floor £10,000 from adjusted income £320,000+. "Adjusted income" includes salary BEFORE sacrifice + employer pension contributions + personal contributions grossed up. So high earners on tapered AA cannot escape the taper via salary sacrifice. Salary sacrifice IS effective for: keeping "threshold income" under £200,000 to avoid the taper kicking in at all (this is the principal high-earner planning use). See our maximum pension contribution calculator for the full AA / MPAA / taper interaction.
Do all employers offer salary sacrifice pension?
Approximately 60-70% of UK employers offer pension salary sacrifice ("smart pension" or "pension+" branded). Required mechanics: a formal contractual variation reducing your gross salary by the sacrifice amount, written confirmation, the sacrificed amount paid by the employer direct to the pension scheme (so it's the employer's contribution legally), updated payroll to apply NI and income tax on the reduced gross. Some employers run "notional" arrangements where they call it salary sacrifice but don't update the legal contract - HMRC may challenge these as not "effective" sacrifice. The contract change must be PROSPECTIVE only (you can't backdate a sacrifice) and typically locked for 12 months (you can't switch on/off freely). Best practice from progressive employers: pass 100% of the employer NI saving (15% from April 2025) through to your pension as a "salary sacrifice top-up". Some employers pass 50% / 0%. Worth asking explicitly. If your employer doesn't offer salary sacrifice, the alternative is "relief at source" or "net pay" - covered in our salary sacrifice vs relief at source guide.
Does salary sacrifice reduce my State Pension entitlement?
In theory yes if your reduced salary drops below the Lower Earnings Limit (LEL) £6,725 for 2026/27 - that would lose your State Pension qualifying year. In practice this is almost never a real risk because: (1) LEL is much lower than any reasonable salary, (2) you only need 35 qualifying years over a working life for full new State Pension, so missing one or two via salary sacrifice is recoverable, (3) most salary sacrifice is for pensions which provides a far better retirement income than the marginal lost State Pension. Genuine risk cases: very high salary sacrifice (>£40k) on a low base salary (~£20k), or part-time workers near NMW. For most professional employees on £40k+ this concern is moot. The reduced salary DOES reduce other reference figures: maternity pay (90% of average earnings in qualifying weeks - sacrifice during those weeks reduces SMP), mortgage affordability calculations (lenders typically use post-sacrifice salary), redundancy pay statutory minimum, sick pay reference earnings, life insurance multiples.
Salary sacrifice vs employer NI top-up - what is "passed through"?
When you sacrifice £X of salary, the EMPLOYER saves 15% × £X of employer NI (from April 2025; was 13.8% before). What happens to that saving varies by employer policy. Best practice (around 40% of large employers): the entire 15% employer NI saving is added to your pension contribution as a "salary sacrifice top-up" or "employer NI rebate". Your £3,000 sacrifice + £450 top-up = £3,450 of pension contribution. Common (around 50% of employers): employer keeps the NI saving entirely as a cost reduction. Your £3,000 sacrifice = £3,000 pension contribution. Hybrid (around 10%): 50/50 split, half passed through, half kept. The employer is NOT obliged to pass through anything - it's a unilateral policy decision. Worth asking HR / payroll directly: "Does our salary sacrifice arrangement pass through the employer NI saving to my pension?" This single question can be worth £450-£2,250 per year depending on your sacrifice amount.
What about the bonus sacrifice route?
Sacrificing a one-off bonus into pension is the most tax-efficient single move available to high earners. A £20,000 cash bonus at higher rate gets taxed: £8,000 income tax (40%) + £400 employee NI (2% in UEL+) = £11,600 net to you. Same £20,000 bonus sacrificed entirely into pension: £20,000 pension contribution (plus potentially £3,000 employer NI top-up if your employer passes through) = £23,000 of pension contribution for £0 net cash cost (you "gave up" the bonus you weren't going to see anyway). Marginal effective rate of "buying" pension via bonus sacrifice: ~50.4% on higher-rate (income tax + NI saved) plus 13% employer-NI top-up if passed through. Bonus sacrifice can be arranged via formal "Bonus Exchange" or "Bonus Waiver" schemes - the bonus must be sacrificed BEFORE it becomes contractually due (typically a window 30 days before payment date). Bonus already declared / accrued cannot be sacrificed (would be "redirection of earned income" - taxable in full). Annual Allowance £60k still applies - cannot exceed via bonus sacrifice without triggering the AA charge.
Can company directors use salary sacrifice?
Yes but with quirks. Solo limited-company directors typically extract a small salary (~£12,570) plus dividends. Salary sacrifice from £12,570 to pension would drop salary below the LEL £6,725, losing State Pension credit year. Better route for directors: have the COMPANY make employer pension contributions directly (no salary sacrifice mechanic needed). Employer contributions: deductible for Corporation Tax, zero income tax to director, zero NI on either side, paid directly to SIPP / SSAS. Annual Allowance £60k applies. Use carry-forward to push up to £240k in single year (current + 3 previous years' AA). For directors with 2+ employees who DO use a meaningful PAYE salary structure, salary sacrifice works the same as for normal employees. The PSC anti-avoidance rules don't specifically restrict director salary sacrifice but HMRC will look at "is this genuinely commercial" if a director with £200k+ company profit pays themselves £12,570 and sacrifices £20k - the optics are bad. See our director pension strategies for the full SSAS / carry-forward / employer contribution mechanics.
What is the £100k personal-allowance taper effect?
Between £100,000 and £125,140 the Personal Allowance is withdrawn at £1 for every £2 above £100k. Marginal effective income-tax rate in this band is 60% (40% IT + 20% PA-loss). Adding 2% employee NI takes the effective marginal rate to 62%. Combined with 15% employer NI saving = 77% effective marginal rate. Salary sacrifice in this zone delivers the HIGHEST per-£ pension benefit anywhere in the UK tax system. £10,000 of sacrifice in this zone saves you £6,000 income tax (60% effective) + £200 employee NI + £1,500 employer NI = £7,700 of saving for a £10,000 pension contribution. Net cost: £2,300 for £10,000 (plus potentially £1,500 employer top-up = £11,500) of pension. This is why the £100k-£125,140 PA taper is the prime salary-sacrifice zone for ambitious accumulators. Some high earners specifically target sacrificing the £25,140 needed to drop adjusted income to £100k flat, recovering the full Personal Allowance.
Are there any downsides to salary sacrifice pension?
Three real downsides to weigh. (1) Locked-in money: pension money is unavailable until age 55 (57 from April 2028, 58 from 2034). Younger high earners need to balance retirement contribution against current-life liquidity needs (deposit, kids' education, business investment). (2) Mortgage affordability: lenders typically use POST-sacrifice salary on affordability calcs. A £80k earner sacrificing £15k looks like a £65k earner to the lender - reduces borrowing capacity by ~£60-75k typical 4x multiple. Pause sacrifice 6-12 months before mortgage application. (3) Statutory pay floors: maternity pay (SMP), sick pay (SSP), redundancy pay are all calculated on reference earnings which can be lower if sacrificing. SMP first 6 weeks is 90% of normal weekly earnings - sacrifice during qualifying weeks reduces SMP. Pause sacrifice 6 months before planned maternity. (4) Marginal upside: tax relief is FRONT-LOADED. The maths only beats ISA route if your marginal tax rate at retirement is LOWER than at contribution - true for most, but not always for very high earners with large pension pots. ISA gives more flexibility at the cost of no front-loaded tax relief.
