Frequently asked questions
- How much tax relief do I get on pension contributions?
- If you sacrifice salary into pension, you save both income tax and National Insurance at your marginal rate. A basic-rate taxpayer saves 28% (20% IT + 8% NI); a higher-rate taxpayer sacrificing above the UEL saves 42% (40% IT + 2% NI).
- Is salary sacrifice better than relief-at-source?
- Usually yes — salary sacrifice also saves the NI your employer would pay, which some schemes split back into your pension. Relief-at-source only gives income tax relief (not NI) without a claim via Self Assessment.
- What is the annual pension allowance?
- £60,000 per tax year for 2026/27 (raised from £40,000 in April 2023; unchanged since), tapered down to £10,000 for very high earners. Contributions above this lose tax relief.
- Can I claim higher-rate relief if my employer only does basic-rate?
- Yes — if your scheme uses relief-at-source and you pay higher-rate tax, you must claim the additional 20% or 25% through Self Assessment. Salary sacrifice gives you full relief automatically.
- Does this include employer contributions?
- No — we model only your personal contribution. Employer contributions go on top and aren't treated as your income.
