How Much Tax Will I Pay on My Pension?

Pension income is not taxed under some special regime: it is taxed as ordinary income, using the same personal allowance and the same bands as a salary. The part that trips people up is the interaction between your tax-free cash, your State Pension and any private pensions, plus the emergency tax that often hits the very first withdrawal. Understanding how the pieces fit together lets you plan withdrawals to keep your tax bill low.

How pension income is taxed

Normally 25% of a defined contribution pot can be taken tax-free. The remaining 75% is added to your other taxable income for the year and taxed at your marginal rate. Everyone gets a personal allowance, £12,570, frozen until 2028, and income above it is taxed in bands. Because the allowance is frozen while pensions rise, more retirees are being drawn into tax each year, a effect worth planning around. Our guide to pension tax relief explains how the same bands work on the way in as well as the way out.

The personal allowance is gradually withdrawn once income passes £100,000, creating an effective 60% rate on that slice, a trap that catches people who take a large taxable lump sum in a single year. Scottish taxpayers have their own bands and rates, with an extra intermediate and advanced band, though the £12,570 personal allowance still applies. As a rule, spreading withdrawals across tax years, rather than taking one big chunk, keeps you in the lower bands.

The mechanics of how the tax is collected matter too. If you have a private pension in payment, HMRC issues it a tax code that mops up the tax due on your State Pension, which is always paid without deductions. That is why the tax taken from your private pension can look higher than you expect: it is covering both. And the very first time you take a taxable lump sum, providers must apply an emergency “month one” code that assumes you will repeat that withdrawal every month for a year. The result is often a large over-deduction; you reclaim it using HMRC forms P55, P53Z or P50Z, or simply wait for the system to reconcile at year end.

The tax-free cash lever

Your 25% tax-free entitlement is the most useful tool for controlling your retirement tax bill, because it lets you top up income in a given year without adding to your taxable total. Someone who needs, say, £30,000 to live on might take part as taxable pension income and part as tax-free cash, deliberately keeping their taxable income below the £50,270 higher-rate threshold. Phasing this cash across many years, rather than taking it all up front, keeps more of the pot growing inside its tax shelter and preserves flexibility. Our guide to the tax-free lump sum sets out the ways to slice it.

A typical retirement tax bill

Consider someone with the full new State Pension of about £12,000 and a private pension paying £16,000 a year. Their total income is £28,000; after the £12,570 allowance, roughly £15,430 is taxed at 20%, a bill of around £3,086. Someone living only on the State Pension pays no income tax at all, because it sits within the personal allowance. The picture changes sharply for those with large pots who withdraw aggressively.

Because withdrawals, allowances and the State Pension interact, a small change in timing can move you across a tax threshold. This is information, not personal advice, and everyone’s position differs. A regulated adviser can build a withdrawal plan that smooths your income and uses both partners’ allowances; Vetted Wealth’s free service matches you with independently vetted advisers across the pension advice network, and you can read more in our pensions guides.
