A pensioner in the UK can receive up to £12,570 a year across all income sources before paying any income tax. That figure is the Personal Allowance, and it has been frozen since 2021 and is set to stay there until at least April 2028. The catch is that the full new State Pension now pays £241.30 a week, or roughly £12,547 a year, which swallows almost the entire allowance on its own. Any workplace pension, part-time wage, rental profit, or savings interest on top pushes you into taxable income.
What the £12,570 Threshold Actually Covers
The Personal Allowance applies to the tax year running from 6 April to 5 April, and it covers your income as a whole rather than each source separately. HMRC adds everything together first and then applies the allowance once.
The sources that get combined include:
- The State Pension, both the new State Pension and the old basic State Pension, plus any Additional State Pension (SERPS or S2P).
- Workplace and private pension income, including occupational pensions, personal pensions, and retirement annuities.
- Wages, salary, or self-employment profits from any work you do after retiring.
- Rental profits after allowable expenses.
- Savings interest and dividends above their own separate allowances.
- Certain taxable state benefits, such as Carer’s Allowance and the taxable element of Bereavement Support Payment. Attendance Allowance and Pension Credit do not count.
Because the £12,570 is a single combined threshold, a retiree with a small workplace pension, a bit of savings interest, and some rental income can slip past it without any one source feeling large.
Why the State Pension Uses Up Nearly All of It
The State Pension is taxable income, even though no tax is deducted before it reaches your bank account. The Department for Work and Pensions pays it gross. HMRC collects the tax owed on it by adjusting the code on your other income instead.
In practice, if you receive the full new State Pension and also draw a workplace pension, HMRC will cut the tax-free amount in your workplace pension code by the value of your State Pension. The workplace provider then deducts tax from almost every pound it pays you. Many retirees miss this because their State Pension statement shows no deduction and they assume it is tax-free. It is not; the tax simply comes out somewhere else.
The freeze matters here. Pensions tend to rise with inflation while the allowance stays put, so each year more retirees cross the line. A decade ago, a full State Pension left hundreds of pounds of unused allowance. Today it leaves about £22.
Allowances That Sit On Top of the £12,570
Several smaller allowances shelter specific types of income before they count against the Personal Allowance threshold.
Personal Savings Allowance
Basic rate taxpayers can earn £1,000 of savings interest a year tax-free. Higher rate taxpayers get £500. Additional rate taxpayers get nothing. With interest rates where they are, pensioners holding meaningful cash savings should check whether they are quietly exceeding this.
Dividend Allowance
The first £500 of dividend income each year is tax-free regardless of your tax band. Dividends above that are taxed at 8.75% for basic rate taxpayers, 33.75% for higher rate, and 39.35% for additional rate.
Trading and Property Allowances
You can receive up to £1,000 from self-employment and £1,000 from property, each year, without owing tax or needing to report it. Useful for occasional freelance work or small lettings. The Rent a Room scheme is separate and lets you earn up to £7,500 tax-free from letting furnished accommodation in your own home.
Tax-Free Pension Lump Sum
When you first access a defined contribution pension, you can take up to 25% of the pot as a lump sum without paying any income tax, capped at £268,275 across all your pensions. This is the Lump Sum Allowance, which replaced the old Lifetime Allowance system. The lump sum does not count toward your Personal Allowance for the year. Anything you draw beyond the 25% is added to your taxable income and taxed at your marginal rate, so a large single-year withdrawal can push you into a higher band.
Adjustments That Raise or Lower Your Allowance
Marriage Allowance
If you are married or in a civil partnership and one of you earns under £12,570, the lower earner can transfer £1,260 of their unused allowance to the higher earner, provided the higher earner is a basic rate taxpayer. The saving is up to £252 a year, and you can backdate a claim for up to four previous tax years.
Blind Person’s Allowance
If you are registered as severely sight impaired, the Blind Person’s Allowance for 2025/26 is £3,130, which effectively lifts your tax-free income to £15,700. Any surplus you cannot use yourself can transfer to a spouse or civil partner.
High-Income Taper
If your adjusted net income goes above £100,000, you lose £1 of Personal Allowance for every £2 over that line. By £125,140 the allowance is gone entirely. This creates an effective 60% marginal rate inside that band, which can catch pensioners who take a large pension withdrawal or crystallise an investment gain in a single tax year.
National Insurance Stops at State Pension Age
Once you reach State Pension age, you stop paying National Insurance on your earnings. If you are employed, show your employer proof of your age so they stop deducting it. If you are self-employed, Class 4 contributions end from 6 April in the tax year after you reach State Pension age.
The saving is real. An employed pensioner earning £30,000 avoids roughly £1,740 a year in NI that a younger worker on the same salary would pay. Income tax still applies in full, but the NI exemption makes working in retirement noticeably more tax-efficient than working before pension age.
How HMRC Actually Collects the Tax
Most pensioners never hand over a cheque. HMRC uses Pay As You Earn, issuing a tax code to each pension provider that tells them how much of your income is tax-free. The provider deducts the right amount before paying you.
When you have more than one income source, HMRC usually assigns the full Personal Allowance to one source and taxes the others from the first pound. Check your coding notice each year. Errors are common whenever pension amounts change or a new source starts, and the sooner you catch a wrong code the smaller the correction.
Scottish Rates Differ Above the Allowance
If you live in Scotland, the £12,570 Personal Allowance is the same, but the rates on income above it are not. Scotland uses a more graduated system starting at 19% and rising through 20%, 21%, and 42% before reaching 45% and 48% at the top. For most pensioners on modest incomes the practical difference is small. Those with larger pensions should check the Scottish rates specifically.
When You Have to File a Self Assessment Return
If all your income is taxed through PAYE on pensions and employment, you will usually never need to file a return. HMRC handles it through the coding system. You do need to register for Self Assessment if you have untaxed income from sources such as rental property, foreign pensions, or self-employment profits above £1,000.
Register by 5 October following the end of the tax year in which the income arose. Once registered, the deadline to file is 31 January online or 31 October on paper. Missing either deadline brings a £100 penalty straight away, with more added the longer you leave it, and separate penalties apply if you pay the tax itself late.
