Salary sacrifice lets an employee give up pay in return for an employer pension contribution, which can cut National Insurance. This guide explains how it works in 2026/27, what changes in April 2029, and what to check, with worked examples.

## How salary sacrifice for pensions works

Salary sacrifice is an agreement in which an employee gives up part of their cash pay and the employer pays a matching amount into the employee's pension instead. GOV.UK explains that it is set up by changing the employment contract, so the employee must agree, and that swapping between cash and the benefit whenever the employee likes can remove the expected tax and National Insurance advantages. Because the employee's pay is lower on paper, Income Tax and National Insurance are worked out on the reduced figure. Pension contributions are one of the benefits that keep their tax and National Insurance treatment under these arrangements, along with workplace nurseries and cycle-to-work schemes. This differs from an ordinary employee contribution, where the employee pays into the pension from pay that has already been counted for National Insurance, even though Income Tax relief still applies.

> **Key numbers** 2026/27 employee National Insurance: 8% on earnings from £12,570 to £50,270 a year, 2% above that. Employer National Insurance: 15% above £5,000 a year. From April 2029: only the first £2,000 a year of salary-sacrificed employee pension contributions stays free of National Insurance. Checked 19 October 2026.

## The figures for 2026/27

In the 2026/27 tax year, GOV.UK's employer rates page sets the employee (primary) threshold at £242 a week, or £12,570 a year, and the upper earnings limit at £967 a week, or £50,270 a year. Employees in the standard category pay National Insurance at 8% between those two points and 2% above the upper limit. Employers pay 15% on earnings above the secondary threshold of £96 a week, or £5,000 a year. These rates matter because salary sacrifice reduces the pay that National Insurance is charged on, so an employee can save the employee rate on the amount given up, and the employer can save the employer rate. Income Tax relief on pension contributions applies either way, up to the limit of 100% of annual earnings that GOV.UK describes, and subject to the annual allowance.

## What changes in April 2029

In its November 2025 guidance, the government announced that from April 2029 only the first £2,000 a year of employee pension contributions made through salary sacrifice will be exempt from National Insurance. The cap applies per employee. Anything above £2,000 will be treated like other employee workplace pension contributions for National Insurance, so both the employee and the employer pay on the excess. Income Tax treatment does not change, and GOV.UK says all employer pension contributions will continue to be free of National Insurance. Employees can still sacrifice more than £2,000 if they wish. Legislation.gov.uk lists the National Insurance Contributions (Employer Pensions Contributions) Act 2026 as a short Act of three sections, and the detailed operation, including employer reporting, is expected to come later through regulations and HMRC guidance. GOV.UK says further guidance will be published before April 2029. Nothing changes for 2026/27.

## Worked examples

These are illustrative only, use 2026/27 rates to show the arithmetic, and the rates in 2029 may differ. For example, suppose an employee earns £30,000 and sacrifices 5% (£1,500) into a pension. Employee National Insurance at 8% on £1,500 is £120 a year, and the employer's 15% on the same amount is £225. Now suppose someone sacrifices £5,000 a year. Today, at 8%, the employee saving would be £400 (8% x £5,000). Under a £2,000 cap, only £2,000 stays exempt, so the saving would be £160 (8% x £2,000), and £3,000 would become chargeable: £240 for the employee (8% x £3,000) and £450 for the employer (15% x £3,000). Finally, someone earning £60,000 who sacrifices 5% (£3,000) is £1,000 over the cap. As their pay is above £50,270, the 2% rate applies, so the extra employee charge would be £20 (2% x £1,000). Many people with typical contributions would not be affected at all.

## Things to weigh up

Lower pay on paper can have effects beyond tax. GOV.UK says salary sacrifice must not take cash pay below the National Minimum Wage, and that lower earnings can affect earnings-related benefits such as Maternity Allowance, and statutory pay, and in some cases can cause entitlement to be lost. Reduced National Insurance can also affect contribution-based benefits such as the State Pension, if earnings fall below the relevant limit. These points are worth checking with the employer, because arrangements differ. Arrangements are also set by employers, not by law, so some employers do not offer salary sacrifice and some offer it only for certain groups.

- Who this applies to: employees whose employer offers a salary sacrifice pension arrangement, anywhere in the UK, with the same National Insurance rules in England, Scotland, Wales and Northern Ireland.
- Who it does not apply to: the self-employed, who cannot use salary sacrifice, and people whose employer does not offer it.
- Common mistake: assuming that all pension contributions are affected by the cap. The cap applies to employee contributions made through salary sacrifice, not to employer contributions.
- Common mistake: focusing only on the National Insurance saving and overlooking effects on statutory pay or benefits linked to pay.
