Pension Tax Relief UK 2026/27: How It Works and How Much You Can Save

Pension tax relief sits alongside the State Pension and workplace saving through auto enrolment. Use our pension calculator to see how contributions and relief affect your retirement pot.

How pension tax relief works

Pension tax relief means the government effectively tops up your pension contributions at your marginal rate of income tax. In England, Wales, and Northern Ireland that is typically 20%, 40%, or 45% depending on your income. Between £100,000 and £125,140, the Personal Allowance taper can push the effective rate to 60 percent. See our 60 percent tax trap guide for how pension saving restores allowance in that band. Scottish taxpayers use Scottish income tax rates on non-savings income instead.

For a basic rate taxpayer, a £100 pension contribution costs £80 once relief is counted. A higher rate taxpayer can effectively fund the same £100 for £60, and an additional rate taxpayer for £55, once the extra relief is claimed.

Relief at source versus net pay

Under relief at source, you pay contributions from taxed income and your pension provider claims basic rate tax relief at 20% automatically. Higher and additional rate taxpayers claim the rest through self assessment or by contacting HMRC.

Under net pay, contributions are deducted from gross pay before income tax is calculated, so you receive full relief through payroll without a separate claim. Many workplace schemes use net pay.

Salary sacrifice goes further: your employer reduces gross pay and pays the amount into your pension, so you save income tax and usually employee National Insurance too. See our income tax calculator to model how marginal rates affect your take-home pay.

The annual allowance

The annual allowance is £60,000 for 2026/27, or 100% of your UK earnings if that is lower. It covers all pension inputs across every scheme you belong to, including employer contributions and tax relief.

Contributions above the allowance can trigger an annual allowance charge, taxed at your marginal rate unless you have unused allowance to carry forward.

The tapered annual allowance for high earners

If your adjusted income is over £260,000, your annual allowance tapers by £1 for every £2 over that level, down to a minimum of £10,000. The taper only applies if your threshold income (broadly income excluding certain pension accrual) is over £200,000.

At adjusted income of £260,000, the allowance is still £60,000. By £360,000, it reaches the £10,000 floor.

The money purchase annual allowance

Once you flexibly access a defined contribution pension (for example through drawdown or taking more than the tax-free lump sum), the amount you can still contribute with tax relief drops to the money purchase annual allowance of £10,000 a year. This applies even if you only take a small flexible withdrawal.

The MPAA is separate from the main annual allowance taper. Taking only your tax-free lump sum under certain conditions may not trigger it, but most flexible access does. See our tax free lump sum guide for how withdrawals interact with the MPAA.

Carry forward

You may be able to carry forward unused annual allowance from the previous three tax years if you were a member of a registered pension scheme in those years. That can let you pay in more than £60,000 in a single year without an annual allowance charge, subject to the earnings limit in that year.

Carry forward is often used after a pay rise, bonus, or self-employed profit spike. You must use the current year allowance first, then the oldest unused year.
