      Under pension salary sacrifice arrangements, employees give up an amount of gross salary in return for enhanced employer pension contributions rather than making their own pension contributions.

      Under current rules, this saves both employee’s and employer’s National Insurance contributions (NIC) (and Apprenticeship Levy for larger employers), whilst maintaining the same level of pension contributions. Indeed, some employers choose to share the employer’s NIC savings with participating employees, increasing the overall pension contributions.

      What's changing?

      As was widely speculated before Autumn Budget 2025, the Chancellor has now confirmed that from 6 April 2029, pension contributions made under salary sacrifice arrangements (i.e., the amounts sacrificed by employees in return for an equal amount of employer pension contribution), will be subject to both employee’s and employer’s NIC to the extent they exceed £2,000 per annum. For example, if total pension contributions under salary sacrifice in one tax year were £5,000, then £3,000 would be subject to employee’s and employer’s NIC under the proposed changes.

      Other employer pension contributions will remain exempt from NIC.

      HMRC have confirmed that salary sacrifice will continue to be effective to retain access to tax-free childcare and/or child benefit.

      HMRC have said that they will engage with stakeholders and publish guidance before April 2029.

      What should employers consider ahead of the changes?

      Whilst this change is some time away, it’s important that employers start to consider its potential impact on their employee pension provision, total reward strategy and wider employee value proposition – particularly given potential future reforms from the new Pensions Commission.

      Issues for employers to consider include:

      • Modelling the cost of pension contributions: employers who operate pension salary sacrifice face higher employer’s NIC and Apprenticeship Levy costs – will the reduced savings continue to fund the operation of your arrangements?
      • The impact across different employee groups: the impact of these changes on different employee segments (e.g., those near auto-enrolment thresholds versus higher earners) will vary – how can you establish what different groups save and how they’ll be affected?
      • Operational and payroll challenges: there will be significant operational implications for payroll systems, reporting, and processes – how will you prepare for the changes required and ensure future compliance?
      • Employee communications: Clear, updated communications (including updated member booklets and payslip explanations) that explain these changes to employees will be essential;
      • Updating Terms & Conditions: it may be necessary to update employment contracts and scheme documentation – is a wider employment communication exercise necessary to ensure employees understand these changes and ensure good employment relations?
      • Pension reporting functionality: there could be challenges in updating and generating accurate pension reports under new rules – how might this impact you?
      • Pension scheme and benefits design: these changes are a catalyst to review overall pension policy and how it fits into the wider benefits strategy; and 
      • Cost reduction strategies: how might your increased costs from this measure be offset by savings that might be made in other aspects of your benefit provision?
