Salary Sacrifice for Additional-Rate Taxpayers (Over £125,140)
Written by James Whitfield · Last reviewed 19 October 2026 · Checked against GOV.UK and HMRC guidance for 2026/27.
If you earn more than £125,140, every pound of salary you give up for your pension comes off income taxed at 45%. Here is what that saves, why the band just below you is worth even more, and the two limits that matter most at this income: the tapered annual allowance and the April 2029 NI cap.
Above £125,140, each £1,000 of pension salary sacrifice saves £450 Income Tax and £20 National Insurance (47%), so it costs you £530 of take-home pay, and your employer saves £150.13 Sacrifice between £125,140 and £100,000 is worth even more, an effective 60% plus 2% NI, because it gives back your Personal Allowance.2 Taking a £150,000 salary down to £100,000 puts £50,000 in your pension for £22,729. Check the £60,000 annual allowance, including employer contributions, before you go that far.5
- Additional rate: 45% on income over £125,140 in England, Wales and Northern Ireland; Scotland's top rate is 48%.17
- Employee NI above £50,270 is 2%; employer NI is 15%, so your employer saves £150 per £1,000.3
- Between £100,000 and £125,140 the Personal Allowance is withdrawn at £1 for every £2, an effective 60% rate.2
- The annual allowance is £60,000, tapered to as little as £10,000 when threshold income is over £200,000 and adjusted income over £260,000.45
- From 6 April 2029 only the first £2,000 a year of pension salary sacrifice will be free of NI.6

What each £1,000 of sacrifice saves
The saving depends on which slice of your pay the sacrifice comes off. Working down from the top of your salary:
| Slice of salary | Tax saved | Your NI saved | Total per £1,000 |
|---|---|---|---|
| Over £125,140 (England, Wales, NI) | 45% | 2% | £470 |
| Over £125,140 (Scotland) | 48% | 2% | £500 |
| £100,000 to £125,140 (England, Wales, NI) | 60% effective | 2% | £620 |
| £100,000 to £125,140 (Scotland, 45% advanced rate) | 67.5% effective | 2% | £695 |
Rates from GOV.UK for 2026/27.127 Your employer saves a further 15% on every slice.3 Assumes no other income.
Worked example: £150,000 salary
England, no other income, no other pension contributions. Two choices: sacrifice just the slice above £125,140, or go all the way down to £100,000.
| Sacrifice £24,860 (to £125,140) | |
| Income Tax saved: £24,860 × 45% | £11,187 |
| Employee NI saved: £24,860 × 2% | £497.20 |
| Cost to your take-home pay | £13,175.80 |
| Employer NI saved: £24,860 × 15% | £3,729 |
| Sacrifice £50,000 (to £100,000) | |
| Income Tax saved: £11,187 + £25,140 × 60% | £26,271 |
| Employee NI saved: £50,000 × 2% | £1,000 |
| Cost to your take-home pay for £50,000 in your pension | £22,729 |
| Employer NI saved: £50,000 × 15% | £7,500 |
The second £25,140 is the better deal: it saves £15,084 of tax because it also restores your £12,570 Personal Allowance.2 Going all the way to £100,000 uses £50,000 of your £60,000 annual allowance, so an employer contribution of more than £10,000 on top would need carry forward to avoid a charge.59 If your employer passes on part of its £7,500 NI saving, that extra counts towards the allowance too.
The tapered annual allowance
Above a certain income your £60,000 annual allowance shrinks. It is reduced only if both tests are failed: threshold income over £200,000 and adjusted income over £260,000. The allowance then falls by £1 for every £2 of adjusted income above £260,000, to a minimum of £10,000.45
Salary sacrifice does not help you pass the threshold income test. For arrangements made after 8 July 2015, salary given up for pension is added back when threshold income is worked out.4 Adjusted income counts all pension contributions, including your employer's, so the sacrifice is in that figure too.
| Salary before sacrifice | £300,000 |
| Pension salary sacrifice (arranged after 8 July 2015) | £30,000 |
| Employer contribution on top | £10,000 |
| Threshold income: £270,000 + £30,000 added back | £300,000 |
| Adjusted income: £270,000 + £40,000 of contributions | £310,000 |
| Annual allowance: £60,000 − (£50,000 ÷ 2) | £35,000 |
| Pension saving of £40,000: excess without carry forward | £5,000 |
An excess is added to your income and taxed at the rates it falls into, here 45%, unless unused allowance from the previous three years covers it.89 The sacrifice itself still saves £13,500 of Income Tax and £600 of NI.
Bonuses and the 2029 NI cap
Large bonuses are where high earners usually sacrifice most. A bonus sacrifice has to be agreed before you become entitled to the bonus, and it counts towards the annual allowance in the year it is paid in, so check the taper in a bonus year. The bonus sacrifice guide covers timing.
From 6 April 2029, only the first £2,000 a year of pension salary sacrifice will be free of National Insurance. Above that, you and your employer will pay NI as on ordinary pay; Income Tax relief does not change.6 At today's rates, the £24,860 sacrifice in the example above would cost you £457.20 more NI a year (2% of £22,860) and your employer £3,429 (15%). The tax years 2026/27 to 2028/29 still get the full NI saving. The 2029 NI cap guide has a quick calculator.
Before you sacrifice a large amount
- Add up all pension saving for the tax year: your sacrifice, any employer contribution and any personal or SIPP contributions. Compare it with £60,000, or your tapered figure.
- Work out threshold and adjusted income if your income is anywhere near £200,000, remembering that the sacrifice is added back.
- Check carry forward from the three previous tax years before assuming a charge; you must have been a member of a registered pension scheme in each year you carry forward from.9
- Ask about the employer's NI saving: £150 per £1,000 is a lot at this level, and some employers pay part of it into your pension.
- Run your own figures in the £100k tax trap calculator or the main calculator.

Frequently asked questions
How much does salary sacrifice save an additional-rate taxpayer?
Each £1,000 sacrificed from pay above £125,140 saves £450 of Income Tax (45%) and £20 of employee National Insurance (2%), so it costs you £530 of take-home pay. Your employer saves £150 (15%). In Scotland the top rate is 48%, so the saving is 50%.
Should I sacrifice down to £100,000 from £150,000?
That is the most tax-efficient range. Sacrificing £50,000 from a £150,000 salary saves £26,271 of Income Tax (the first £24,860 at 45%, the next £25,140 at an effective 60%) and £1,000 of NI, so £50,000 reaches your pension for £22,729 of take-home pay. Check the £60,000 annual allowance first, including any employer contributions.
Does salary sacrifice reduce threshold income for the tapered annual allowance?
Not if the arrangement was made after 8 July 2015. Salary given up for pension under those arrangements is added back when working out threshold income, so a new sacrifice cannot bring threshold income down to £200,000.
When does the tapered annual allowance apply?
Only when threshold income is over £200,000 and adjusted income is over £260,000. The £60,000 allowance then falls by £1 for every £2 of adjusted income over £260,000, to a minimum of £10,000.
What will the April 2029 NI cap cost a high earner?
From April 2029 only the first £2,000 a year of pension salary sacrifice is free of National Insurance. At today's rates, sacrificing £24,860 would mean 2% employee NI on £22,860 (£457.20) and 15% employer NI (£3,429). The Income Tax saving is unchanged.
