Key Rules & Limitations
National Minimum Wage Floor
Salary sacrifice cannot reduce your cash pay below the National Minimum Wage (£12.21/hr for 23+ in 2025/26). Your employer must check this.
Impact on Benefits
Reduced salary may affect: mortgage affordability assessments, statutory maternity/paternity pay (based on actual pay), state pension credits, and student loan repayments. The effect on most people is small, but check before committing to large sacrifices.
Contract Changes
Salary sacrifice is a contractual change — you agree to a lower salary in exchange for the benefit. Most schemes run for 12 months minimum. You typically cannot opt out early unless there is a "life event" (marriage, new child, redundancy).
Pension Annual Allowance
Total pension contributions (yours + employer) cannot exceed £60,000/year or 100% of earnings (whichever is lower). Excess is taxed. You can carry forward unused allowance from the previous 3 years.
