Personal Savings Allowance checklist: how much savings interest can you earn tax-free?

By FastBuySale Newsroom · 5 Nov 2026 · 40m ago

Checklist step 1: work out your tax band and allowance

This Personal Savings Allowance checklist gives the short answer first: official UK government guidance says basic-rate taxpayers can earn up to £1,000 of savings interest a year without paying tax on it, higher-rate taxpayers £500 and additional-rate taxpayers £0. Interest inside an ISA does not count and is tax-free on top of the allowance.

Some people on low incomes can also use the starting rate for savings, worth up to £5,000 of tax-free interest, alongside the Personal Savings Allowance. Interest above your allowances is taxed at your usual Income Tax rate.

Your allowance depends on your Income Tax band. official UK government guidance's table is simple: basic rate £1,000, higher rate £500, additional rate £0.

Important detail: to work out your band, add all the interest you have earned to your other income. A pay rise, a bonus or a large lump of interest can push you into the higher-rate band and halve your allowance, so check your total, not just your salary. Our helps you estimate your take-home pay and band.

The allowance covers interest from bank and building society accounts, savings and credit union accounts. official UK government guidance lists these as the types of savings interest you may pay tax on. Interest in ISAs and some National Savings and Investments products is not usually taxed and does not use up your allowance.

Joint accounts: HMRC splits interest equally between account holders unless you tell it the split should be different. If you share a £20,000 account with a partner, each of you is treated as earning half of the interest.

Several accounts: HMRC adds together the interest from all your savings accounts to find your total. Having many small accounts does not give you extra allowances.

Readers evaluating Personal Savings Allowance should separate marketing claims from the actual rule text that governs their account or product. When two summaries disagree, the governing document or statute wins. If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier.

Educational explainers like this one cannot replace personalized advice for complex situations such as divorce orders, inherited accounts, or cross-border tax residency. Escalate those cases to a qualified professional. When in doubt about a number that changes every year, describe your plan qualitatively first, then look up the current official figure for the tax year you care about before you act.

Checklist step 2: check the starting rate for savings

official UK government guidance says that if your other taxable income, not counting savings interest or dividends, is less than £17,570, you can get the starting rate for savings, which lets you earn up to £5,000 of interest tax-free.

The starting rate shrinks as other income rises. Every £1 of other income above your Personal Allowance reduces the starting rate by £1. official UK government guidance gives the Personal Allowance as £12,570.

official UK government guidance's worked example: you earn £16,000 of wages and £200 of interest. The first £12,570 of wages uses your Personal Allowance. The remaining £3,430 reduces your starting rate from £5,000 to £1,570, so your £200 of interest is not taxed.

You can get the starting rate for savings as well as a Personal Savings Allowance. That is why retired people with modest pensions, part-time workers and students with savings often pay no tax on interest at all.

If your income is near £17,570, write out your income sources for the year, including pensions and any self-employed profits, before assuming you qualify.

A useful habit is to write down your goal, time horizon, and cash buffer before you change any election related to Personal Savings Allowance. Decisions made during a stressful week are the ones people reverse later at a cost. Educational explainers like this one cannot replace personalized advice for complex situations such as divorce orders, inherited accounts, or cross-border tax residency. Escalate those cases to a qualified professional.

Checklist step 3: estimate your interest for the year

Interest counts in the tax year it is paid or credited to you, so a fixed-rate bond that pays all its interest at maturity can create a large one-off amount in a single year. Compare monthly-interest and maturity options before you lock money away.

Quick maths: £20,000 earning 4% gives about £800 of interest a year, inside a basic-rate taxpayer's £1,000 allowance. The same £20,000 at 4% for a higher-rate taxpayer goes £300 over the £500 allowance. Model your own balance and rate with the

official UK government guidance's example: HMRC estimates you earned £1,300 of savings interest. As a basic-rate taxpayer your allowance is £1,000, so the first £1,000 is not taxed and the remaining £300 is taxed at 20%, giving £60 of tax.

Remember inflation. Even tax-free interest can lose value in real terms if the rate is below inflation; check with the

Plan around changes in the year. If you expect a promotion, a new job or a pension to start, your band could change mid-way through the tax year, and the allowance that applies is the one for your band across the whole year. Re-run this checklist whenever your income changes, and spread large deposits across accounts and ISAs so the interest lands where it is taxed least.

Keep digital and paper copies of confirmations after every change. Screenshots of election pages, email receipts, and year-end statements make tax season and job changes far less chaotic. Compare fees the same way you would compare two similar listings before you buy: look at what you pay each year, what you get, and whether a simpler option meets the same need.

Checklist step 4: know how the tax is collected

After 5 April each year, your bank or building society tells HMRC how much interest it paid you in the previous tax year. You do not need to tell your bank your tax band.

If your savings interest is £10,000 or less and you are employed or get a pension, HMRC usually sends a tax calculation if you owe anything. official UK government guidance says these are usually sent between June and the following March after the tax year ends, and may appear in your Personal Tax Account.

If you already send a Self Assessment tax return, report savings interest there.

Check any calculation you receive. It usually lists your savings accounts and the interest from each one, so compare it with your bank statements and contact HMRC if something is wrong, such as a joint account split incorrectly.

When to use an ISA: if your interest is close to or above your allowance, moving savings into a cash ISA keeps future interest out of the calculation. Read our guide for the £20,000 ISA allowance and the 2027 changes, and see for first-home savers.

If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier. Automation helps. Calendar reminders for annual reviews, automatic transfers, and beneficiary checkups reduce the chance that a good plan dies from neglect.
