Pension salary sacrifice: the planned £2,000 NI limit
6 April 2029 · Enabling Act passed; detailed rules pending
The announced change limits National Insurance relief on pension salary sacrifice to £2,000 a tax year. It is a limit on the relieved contribution amount, not a £2,000 pension contribution ceiling.
What is changing?
Salary sacrifice, also called salary or bonus exchange, involves giving up contractual pay in return for an employer pension contribution. HMRC's policy sets 6 April 2029 as the start date for charging employee and employer Class 1 National Insurance on the amount sacrificed above £2,000 in a tax year.
The National Insurance Contributions (Employer Pensions Contributions) Act 2026 received Royal Assent on 29 April 2026. It creates powers to implement the change through regulations. HMRC says the design and operation of the limit will be set out in secondary legislation, so payroll details should be checked against the final rules.
What does the £2,000 figure mean?
It refers to the annual amount of pay exchanged for pension contributions that retains the National Insurance exemption. It is not £2,000 of tax savings and it does not cap the total amount someone may contribute to a pension.
Illustrative, not advice: if £5,000 were exchanged during a tax year under the announced policy, £2,000 would remain within the exemption and £3,000 would be subject to the applicable National Insurance rules. The resulting cost depends on the rates, earnings and payroll rules in force at that time. This example does not predict future rates.
Which reliefs remain?
The announced measure leaves pension Income Tax relief in place, subject to the usual limits. It also leaves National Insurance relief on ordinary employer contributions that are not made in exchange for salary. Treasury guidance says employers will make the required payroll changes and employees do not need to contact HMRC simply because of this reform.
The practical question for a member is how their employer's contribution arrangement works, including any sharing of National Insurance savings. The announcement alone does not establish how an employer will change its benefits or contribution policy before 2029.
