Reeves Salary Sacrifice and the National Living Wage: Common Myths and Mistakes

Reeves Salary Sacrifice and the National Living Wage: Common Myths and Mistakes

Understanding how salary sacrifice interacts with the National Minimum Wage is essential for UK workers, especially with the upcoming changes to pension contributions. The Reeves salary sacrifice cap, announced in the Autumn 2025 Budget, will limit National Insurance relief on pension salary sacrifice from April 2029. But there are several myths and mistakes that could catch you out.

Myth 1: Salary sacrifice can reduce your hourly pay below the minimum wage

This is false. UK law is clear: any salary sacrifice arrangement must not bring your gross hourly pay below the statutory minimum wage for your age group. For workers aged 21 and over, the National Living Wage is £12.71 per hour from April 2026. For 18-20 year olds, the rate is £10.85, and for under-18s and apprentices it is £8.00. If your employer tries to push your pay below these floors, they face HMRC penalties of 200% of the underpayment, with a minimum fine of £100 and a maximum of £20,000 per worker. Always check your contract and payslip to ensure your hourly rate stays above the legal minimum. For more on current rates, see our pay guides.

Myth 2: The Reeves salary sacrifice cap applies now

Many workers think the cap on NIC relief is already in place. In fact, it does not start until 6 April 2029. For the 2026/27 tax year, salary sacrifice pension contributions still enjoy unlimited National Insurance exemptions. The cap is a future change, so you can continue to benefit from full NIC savings on your pension contributions until then. However, it is wise to plan ahead if you sacrifice large amounts.

Myth 3: The cap only affects high earners

While higher earners are more likely to sacrifice large sums, the cap can also affect middle earners. The threshold is £2,000 per employee per tax year. If you earn £50,000 and sacrifice 8% (£4,000), you exceed the cap by £2,000. That excess will attract employee NICs at 8% (or 2% above the Upper Earnings Limit of £50,270) and employer NICs at 15%. The extra cost is modest for many, but it is not limited to the very wealthy. Check your contributions against the £2,000 limit to avoid surprises.

Myth 4: Salary sacrifice is being scrapped entirely

No. The Reeves salary sacrifice policy introduces a cap on NIC relief, not an outright ban. The scheme itself continues. Standard workplace pension contributions paid outside a salary exchange agreement remain completely exempt from employer NICs. Income Tax relief on pension contributions is also unaffected. Basic-rate taxpayers who contribute under the £2,000 cap will see no change to their net pay.

How the cap works in practice

From 6 April 2029, any salary sacrifice pension contribution above £2,000 per year will be treated as ordinary earnings for National Insurance purposes. Your employer must record the exempt and liable portions separately in payroll. The first £2,000 remains free of employee and employer NICs. The excess is subject to:

• Employee NICs at 8% (primary rate) within the primary earnings band, or 2% above the Upper Earnings Limit.
• Employer NICs at 15% (secondary rate).

For example, an employee on a £50,000 salary sacrificing 8% (£4,000 per year) exceeds the cap by £2,000, incurring an extra annual employee NIC bill of £160 (8% of £2,000). The employer also pays an extra £300 in NICs. This is a real cost, but it does not affect the pension contribution itself.

Minimum wage compliance remains key

Employers must ensure that any contractual salary reduction never drops an employee’s gross hourly pay below the statutory National Living Wage. For 2026/27, that means £12.71 per hour for workers aged 21 and over. If you are on a salary sacrifice arrangement, check that your hourly rate after the sacrifice stays above this floor. If it does not, the arrangement is illegal. You can use our pay data page to compare your pay against current statutory rates.

Accommodation offset and other rates

If your employer provides living accommodation, the daily offset amount rises to £11.10 from April 2026. This is the maximum you can be charged for accommodation provided as part of your employment. It is separate from the minimum wage but relevant for workers in sectors like hospitality or agriculture.

Final thoughts

The Reeves salary sacrifice cap is a significant change, but it is still a few years away. In the meantime, focus on ensuring your pay meets the legal minimums. The National Living Wage and National Minimum Wage rates for 2026 are set to rise ahead of inflation, providing a real-terms increase for low-paid workers.
