Are Pensions Taxable? UK Tax Rules Explained for 2026

Published 9 March 2026 • 8 min read

Yes, pensions are taxable in the UK — but not in the way many people expect. You get generous tax relief when you pay in, tax-free growth while invested, and a 25% tax-free lump sum when you withdraw. Only the remaining 75% is taxed as income. Here is exactly how it works.

Quick answer: 25% of your pension is tax-free. The other 75% is taxed at your marginal income tax rate (20%, 40%, or 45%). The State Pension is also taxable but no tax is deducted at source.

How Pension Tax Works: The Three Stages

UK pensions follow an EET model — Exempt, Exempt, Taxed:

Going in (Exempt): You receive tax relief on contributions — a basic-rate taxpayer pays £80 and the government adds £20
Growing (Exempt): Investment gains and income within your pension are completely tax-free
Coming out (Taxed): 25% is tax-free; the rest is taxed as income at your marginal rate

This makes pensions one of the most tax-efficient savings vehicles available. Even though withdrawals are taxed, most people pay less tax coming out than they saved going in — because they are typically in a lower tax bracket in retirement.

The 25% Tax-Free Lump Sum

When you access your pension from age 55 (rising to 57 from April 2028), you can take up to 25% completely tax-free. This is called the Pension Commencement Lump Sum (PCLS). For most people, this is one of the most valuable pension benefits.

There are different ways to take your tax-free cash:

All at once — take the full 25% upfront when you enter drawdown
Gradually via UFPLS — take ad-hoc lump sums where 25% of each is tax-free
In stages — crystallise portions of your pension at different times

Important: The tax-free lump sum is capped at £268,275 (25% of the old Lifetime Allowance of £1,073,100). If your total pensions exceed this, the excess is taxed as income.

Income Tax on Pension Withdrawals

After the 25% tax-free amount, all pension withdrawals are added to your other income and taxed at your marginal rate:

£0 – £12,570 (Personal Allowance): 0% tax
£12,571 – £50,270: 20% basic rate
£50,271 – £125,140: 40% higher rate
Above £125,140: 45% additional rate

The key point: the State Pension counts as taxable income and uses up most of your Personal Allowance. With a full State Pension of £11,502, you only have £1,068 of allowance left before private pension withdrawals start being taxed at 20%.

Is the State Pension Taxable?

Yes, the State Pension is taxable income. However, no tax is deducted before you receive it. HMRC collects the tax by adjusting your PAYE code on any other income, or through self-assessment.

The full new State Pension (£11,502/year) is below the Personal Allowance (£12,570), so on its own it is not taxed. But if you have any other income, the State Pension effectively uses up your tax-free allowance first.

How to Minimise Tax on Your Pension

Spread withdrawals across tax years — stay within the basic-rate band each year
Use your full Personal Allowance — withdraw up to £12,570 tax-free if you have no other income
Take advantage of years before State Pension — your full Personal Allowance is available for pension withdrawals
Use both spouses’ allowances — a couple can withdraw over £100,000 before hitting higher-rate tax
Consider UFPLS — each lump sum is 25% tax-free, which can be more flexible than taking all tax-free cash upfront

The Emergency Tax Trap

When you first withdraw from your pension, your provider may apply an emergency tax code. This treats the withdrawal as if you receive that amount every month — resulting in far too much tax being deducted.

For example, a £20,000 withdrawal might be taxed as if your annual income is £240,000. You can reclaim overpaid tax using HMRC forms P50Z, P53, or P55 — or wait for your tax code to be corrected, which can take months.

Tax on Pension Death Benefits

Pension death benefit tax depends on your age:

Death before 75: Beneficiaries receive pension benefits completely tax-free
Death at 75 or over: Beneficiaries pay income tax at their marginal rate on withdrawals

This makes pensions one of the most tax-efficient ways to pass on wealth — they generally sit outside your estate for inheritance tax purposes too.
