Does salary sacrifice affect pension annual allowance? It does not lower the limit, but what your employer pays in counts towards it.

Sacrificing more could take you near the limit, which turns on all your pots rather than one payslip. A call about your pots and earlier years is on offer from an FCA-authorised adviser if that worries you; you set it up through the form on this page.

Is salary sacrifice counted in your pension annual allowance?

Yes. In a salary sacrifice arrangement you agree to give up part of your gross pay and your employer pays that amount into your pension instead. HMRC's Pensions Tax Manual then counts the payment as one made by the employer: for a money purchase arrangement, the amount that counts includes "any contribution paid in respect of the member by an employer of the member."

GOV.UK's annual allowance guide says the same in plainer words. What counts is "the total amount paid in to a defined contribution scheme in a tax year by you or anyone else (for example, your employer)". According to GOV.UK, the standard allowance is £60,000 for the 2026/27 tax year, and it covers all your private pensions together, not each pot separately; the annual allowance guide covers the limit itself.

So the sum that matters is the whole amount reaching the pension, not the bit you can see leaving your payslip. Each pound of salary sacrificed uses a pound of allowance, exactly as an employer paying the same amount in without any sacrifice would. Employer top-ups, matched contributions and any other payments from you or from someone else add to the same total. Contributions you pay yourself, such as AVCs paid alongside salary sacrifice, are counted too, as the guide above says, and the way each type of payment is taxed is on the salary sacrifice tax page.

Final salary and career average schemes measure the allowance differently, using the growth in the value of your pension rather than the money paid in, which the defined benefit allowance guide explains.

Can salary sacrifice keep your income below the taper thresholds?

No, not for arrangements made after 8 July 2015. Higher earners can have a reduced ("tapered") allowance, but GOV.UK says that needs a threshold income above £200,000 and an adjusted income above £260,000 in the same year. Sacrificing salary might look like a way to push threshold income under the first of those limits, and the rules were written to close that route.

HMRC's guidance for working out threshold income tells you to "Add any reduction of employment income for pension provision through any relevant salary sacrifice arrangements made after 8 July 2015." The Pensions Tax Manual defines such an arrangement as one where an individual gives up employment income in exchange for pension contributions by an employer. The pay you gave up is therefore put back in before the £200,000 test is applied. An arrangement made on or before 8 July 2015 is not a relevant one under that definition, so pay given up through it is not added back to threshold income, although your employer's payments still count in adjusted income.

Adjusted income gets the same result from the other side. HMRC's steps for it begin from your net income and then add the amount your employer paid in for you, which for money purchase pensions includes salary sacrifice payments. Employer contributions count whichever way the pay was arranged, so sacrificing salary does not shield you from the taper. For how the reduction itself is worked out, see the tapered allowance guide and the page on employer contributions and adjusted income.

A separate HMRC anti-avoidance rule can also set aside a plan where cutting the taper is the main purpose, or one of the main purposes, and lower income in one tax year is made up by higher income in a different one. Whether that rule reaches your own plans, or whether changing a pre-2015 arrangement counts as making a new one, can be checked free with an adviser on the call that follows your form.

How does salary sacrifice fit with carry forward?

It uses your allowance first, and carry forward tops it up afterwards. Once the current year's allowance is used up, GOV.UK says "You might be able to carry over any annual allowance you did not use from the previous 3 tax years." Your available allowance is then your reduced allowance, if you have one, plus any unused allowance from those earlier years.

Where you have unused allowance, that can make a large salary sacrifice, perhaps from a bonus or a one-off payment, easier to fit in than the £60,000 figure suggests. The sacrificed amount is counted against the current year's allowance and then against what is left from the earlier years. The conditions for carrying forward are in the carry forward guide.

If the total still goes over, the excess is added to your taxable income for the year and taxed at your own rate, as explained on the annual allowance charge page. Anyone who has already started taking flexible income from a pot may have a lower limit again, covered in the money purchase allowance guide.

Does the April 2029 National Insurance cap change the annual allowance?

No. The cap is about National Insurance, not the allowance. The Treasury's paper of 26 November 2025 says "only the first £2,000 of employee pension contributions through salary sacrifice each year will be exempt from NICs" from April 2029, and that these contributions "will still be exempt from Income Tax (subject to the usual limits)". The Act that puts this into law, the National Insurance Contributions (Employer Pensions Contributions) Act 2026, says its amendments "have effect for the tax year 2029-30 and subsequent tax years."

The annual allowance is an Income Tax limit (GOV.UK says any excess is added to your taxable income), and the Income Tax exemption stays, so what falls away from April 2029 is the National Insurance saving on amounts sacrificed above £2,000 a year. That is the effect to plan for, and the page on the salary sacrifice changes sets out the dates and who is affected. How the sacrifice itself is capped by pay rules is on the maximum salary sacrifice page.

Salary sacrifice and the allowance: your questions

Is the pension annual allowance the same with or without salary sacrifice?

The limit is the same, and so is what counts against it. A contribution paid by salary sacrifice and one paid by the employer in the ordinary way both count as employer contributions. Only your pay changes.

Do I pay tax on a salary sacrifice contribution above the allowance?

The excess over your available allowance is added to your taxable income for the year and taxed at your own rate, according to GOV.UK. Your pension provider should send a statement if you go over in their scheme, and you report the amount on a Self Assessment return.

Does the allowance limit the relief on what I sacrifice?

Relief and the allowance are separate checks. The tax relief guide covers how relief is given, and the allowance only decides whether a charge applies on top.

Does sacrificing a bonus count differently from sacrificing salary?

The Treasury describes salary sacrifice as agreeing to "reduce your gross salary or sacrifice a bonus", and the amount your employer pays in is what counts either way. How your own scheme treats a bonus is for your employer or scheme to confirm.

How do I find out how much I have paid in?

GOV.UK says each scheme may send you an annual pension savings statement for the tax year, and if one has not arrived you can ask the scheme's administrators for it. If you are not sure how salary sacrifice figures were reported, an adviser can look at your statements with you.

Before you agree a bigger sacrifice

Whether you are anywhere near the limit depends on every pot you have, your earlier years and your income. If you want those lined up before you agree a sacrifice, the form here asks for a call where an FCA-authorised adviser goes through all of it, free.
