Pension contributions under salary sacrifice: Recent budget update

1 December 2025 | Alasdair Friend

The recent UK Budget has introduced significant reforms to the way pension contributions made under salary sacrifice arrangements will be treated for National Insurance purposes.

A salary sacrifice arrangement is when employees sacrifice their earnings in return for an equal amount of employer pension contribution. Please see below an update regarding the key changes:

  • Effective date: From 6 April 2029
  • NIC treatment: Pension contributions made under salary sacrifice arrangements will be subject to both employee’s and employer’s NICs on the portion that exceeds £2,000 per annum
  • Other employer contributions: Remain exempt from NICs
  • Salary sacrifice benefits: The arrangement will continue to be effective for retaining access to tax‑free childcare and/or child benefit
  • Next steps: HMRC will consult with stakeholders and issue detailed guidance before April 2029
