Autumn Budget 2025 – Pension changes

The Chancellor has kept the main pension allowances unchanged but has confirmed a new cap on salary sacrifice arrangements that will apply from April 2029.

There had been heated speculation that the Chancellor would change the pension rules to help the government raise taxes, but no changes were announced to the annual allowance (which remains at £60,000) or to the carry-forward rules which can use up previous year’s annual allowances. The lump sum allowance has also remained unchanged at £268,275.

However, the Chancellor announced changes to the salary sacrifice arrangements for pension contributions. Salary sacrifice allows employees to reduce part of their salary or bonus in exchange for pension contributions, which is tax-efficient and helps save for retirement. However, this arrangement has disproportionately benefited higher earners with salary sacrifice costs expected to rise from £2.8 billion in 2016-17 to £8 billion by 2030-31.

From April 2029, the government plans to introduce a cap on salary sacrifice contributions which will limit the amount that can be sacrificed without incurring National Insurance Contributions (NICs) to £2,000 per employee. Salary sacrifice contributions above this amount will be subject to employer and employee NICs. Pension contributions that are not part of a salary sacrifice will remain unchanged.

The Chancellor reaffirmed the government's commitment to maintaining the Triple Lock on the State Pension throughout this parliament. This means that in April 2026, the State Pension will increase by 4.8%. The Triple Lock ensures that the State Pension rises by the highest of three measures: inflation, wage growth, or 2.5%, helping to protect pensioners' income against rising costs of living.

Also, starting from 6 April 2027, the government will close a loophole that allows individuals to use pensions for inheritance tax (IHT) planning. Under the new rules, any unspent pension pots will be brought within the scope of IHT.
