✅ Best free salary exchange calculators
By the end, you’ll know exactly how to leverage salary exchange to save on taxes, boost your pension, and maximize earnings.
1. What is Salary Exchange (Salary Sacrifice)?
Salary exchange (or salary sacrifice) is an arrangement where an employee agrees to give up part of their pre-tax salary in exchange for non-cash benefits. These benefits can include:
- Pension contributions (most common)
- Company cars (electric vehicles are tax-efficient)
- Childcare vouchers
- Cycle-to-work schemes
- Private medical insurance
How It Works
- Your employer reduces your gross salary by the sacrificed amount.
- You receive the benefit tax-free (or at a reduced tax rate).
- Because your taxable income decreases, you pay less Income Tax and National Insurance (NI).
- Employers also save on Employer NI contributions, making it a win-win.
Example:
- Original Salary: £50,000
- Sacrifice £5,000 into a pension
- New Taxable Salary: £45,000
- Tax Savings: ~£1,000 (depending on tax bracket)
- NI Savings: ~£500
- Take-Home Pay Impact: Only ~£3,500 net loss for a £5,000 pension boost!
