How salary sacrifice works

You agree with your employer to give up part of your gross salary in exchange for a benefit of equal value. The deduction happens before Income Tax and National Insurance, so you save both on the sacrificed amount.

Frequently asked questions

What can I sacrifice my salary for?
Common UK schemes: pension contributions, cycle-to-work (bikes + accessories), EV car lease, childcare vouchers (legacy — closed to new joiners), holiday buy, technology schemes, gym memberships. All reduce your gross salary pre-tax.
How much tax do I save?
The sacrifice is deducted before Income Tax and National Insurance, so you save both. Basic-rate: 28% (20% IT + 8% NI). Higher-rate above UEL: 42% (40% IT + 2% NI). Additional rate: 47% (45% IT + 2% NI).
Are there any downsides?
Lower gross salary means: lower mortgage borrowing capacity, lower pension auto-enrolment base (if not on salary sacrifice), reduced maternity/redundancy pay, and lower state pension credits if you drop below the Lower Earnings Limit (£6,396).
Is salary sacrifice always allowed?
No — your employer must offer the scheme and HMRC must approve the benefit type. Your reduced salary cannot fall below the National Minimum Wage.
Does this include employer NI savings?
We model only your personal tax and NI saved. Employers also save 13.8% NI on the sacrificed amount — some generous schemes pass this back into your pension.
