Personal Savings Allowance Explained: What It Is, Why Higher Rates Mean You Might Owe Tax, and How to Stay Within It

For most of the last decade, the tax on your savings interest was a non-event. Rates were so low that almost nobody earned enough interest to owe anything, and the Personal Savings Allowance quietly mopped up the rest. That has changed. A growing number of savers are now opening a letter from HMRC saying their tax code has been adjusted, or getting a message from their bank confirming it has reported the interest it paid them. The figures behind those letters are not large in isolation, but they catch people off guard because nothing changed in how they save. What changed was the interest rate. When savings paid next to nothing, you needed a small fortune to breach the allowance. At the rates available now, a fairly ordinary balance can tip you over. This guide explains what the Personal Savings Allowance is, why higher rates have pulled so many people into paying tax on interest for the first time, and the practical steps that keep you within it.

What Is the Personal Savings Allowance?

The Personal Savings Allowance (PSA) is the amount of interest you can earn each tax year before any tax is due on it. For a basic-rate taxpayer it is £1,000. For a higher-rate taxpayer it is £500. Additional-rate taxpayers get no allowance at all. These figures have not moved since the allowance was introduced in April 2016, which is part of why it now bites for more people: the thresholds stayed still while interest rates climbed.

Your allowance is set by your tax band, and the table below shows how the two line up for the 2026/27 tax year.

One point trips people up more than any other: the PSA sits on top of your £12,570 personal allowance, it does not replace it or overlap with it. The personal allowance covers your income in general. The savings allowance is a separate slice that applies specifically to interest. Savings interest still counts as income, though, and it stacks on top of everything else you earn. That ordering matters, because it is your total taxable income that decides which band you fall into, and therefore whether your savings allowance is £1,000, £500 or nothing. Someone whose salary sits just under the higher-rate threshold can be tipped into it by their savings interest, which both raises their tax rate on part of that interest and halves the allowance protecting it.

The allowance covers interest from a broad set of sources. That includes ordinary savings accounts, the interest some current accounts pay, credit-union accounts, government bonds (gilts) and corporate bonds, and returns from peer-to-peer lending. If a product pays you interest, assume it counts towards the PSA unless you have a specific reason to think otherwise.

Two things sit outside it entirely. Interest earned inside an ISA is always tax-free and never touches your PSA, which is the single most useful fact in this whole topic. Premium Bond prizes are also tax-free and do not count, because they are technically winnings rather than interest. Everything else you earn in interest is measured against your allowance, and once you cross it, the excess is taxed at your usual income tax rate.

If you are used to the US system, this works quite differently there. The United States has no direct equivalent to the PSA: savings interest is generally taxed as ordinary income from the first dollar, with no tax-free band carved out specifically for it. The UK approach of a dedicated allowance, however eroded by frozen thresholds, is more generous than many savers realise.

Why This Matters Now: The Higher-Rates Problem

Rewind to 2016, when the PSA launched. The Bank of England base rate was 0.25%, and the best savings accounts paid only a little more. At those rates the £1,000 basic-rate allowance was almost impossible to breach. You would have needed something in the region of £400,000 sitting in savings to earn £1,000 of interest in a year. For the overwhelming majority of savers, the allowance was a comfortable ceiling they would never reach, and tax on interest simply faded from view.

Then rates moved sharply. From 2022 onwards the Bank of England raised the base rate to tackle inflation, and savings rates followed. The base rate has since eased back to 3.75% by mid-2026, so the peak is behind us, but rates have not returned to the near-zero era. The best easy-access accounts still pay around 4.8%, and plenty of ordinary accounts pay in the region of 4%. The arithmetic of the allowance has been transformed by that shift. At roughly 4.5%, the balance that produces £1,000 of interest is not £400,000, it is about £22,000. The £500 higher-rate allowance is breached at around £11,000. Balances that never came close to the allowance a few years ago now sail past it.

HMRC has the data to act on this. Banks and building societies report the interest they pay you automatically each year, so there is no hiding a breach and no need to declare small amounts yourself in most cases. The combination of higher rates and automatic reporting is why so many people are hearing about the PSA for the first time. The table below shows where the tipping points fall at a competitive 4.5% rate, for both the basic-rate and higher-rate allowances.

A worked example makes the consequence concrete. Take a higher-rate taxpayer with £30,000 in savings, earning interest at 4.5%. That produces £1,350 of interest in the year. Their allowance is £500, so £850 of it is taxable. At the higher rate of 40%, that comes to £340 of tax, which HMRC will normally collect automatically by adjusting their tax code rather than sending a bill. Worth noting: these tipping points move with the interest rate. If rates fall, you need a larger balance to breach the allowance, so the thresholds in the table would shift upwards. The numbers here assume rates stay near current levels.

What Happens When You Exceed the PSA?

The process is mostly invisible, which is exactly why it surprises people. After each tax year ends in April, every bank and building society sends HMRC a record of the interest it paid you. HMRC adds it all together, sets it against your allowance, and works out the tax due on anything above the line. You do not have to lift a finger for any of this to happen.

For most people, HMRC then collects the tax by changing their tax code for the following year. Your code carries an allowance figure baked into it, and HMRC reduces that figure to claw back the expected tax through PAYE over twelve months. In practice your code number drops, for example from 1257L to something lower, and slightly more tax comes out of each payslip. If you want the mechanics of how a code is built and what the letters and numbers mean, our guide to UK tax codes explained walks through it.

The catch is timing. Because the adjustment happens the year after the interest was earned, the letter announcing it often lands with no obvious trigger. You did not change anything, you simply earned more interest than the allowance covered, and the first you hear of it is a coding notice. That lag is the most common reason the PSA feels like an unpleasant surprise rather than a known rule.

You will see the effect on your payslip rather than in a separate bill. A lower code means a smaller tax-free portion of your pay, so your take-home drops a little even though your salary has not changed. If the gap between what you earn and what lands in your account is something you have ever puzzled over, our explainer on gross and net pay covers how deductions like this flow through.

Not everyone is collected through PAYE. If your interest is large, or you already complete a Self Assessment return because you are self-employed, a landlord, or have other untaxed income, the tax on your savings interest goes through that return instead. People with no PAYE income at all, such as some retirees living on savings and pensions, may also need to report it via Self Assessment. If HMRC writes to you asking you to register, that is the route you will use, and the tax becomes payable as part of your annual bill rather than spread across your salary.

How to Check If You've Exceeded (or Will)

You do not have to wait for HMRC to tell you. A few minutes with your own paperwork will show whether you have crossed the line, or are about to. The aim is simple: add up every penny of taxable interest you expect this year, then hold it against the allowance your tax band gives you.

Start with the tax certificate. Each April, banks and building societies can issue an annual interest statement, sometimes called a tax certificate or a certificate of interest, showing exactly how much they paid you in the tax year. Many make it available in online banking even if they do not post one out. These statements are the cleanest record of what HMRC will see.

Add up every account. The allowance applies to your interest in total, not per account, so a string of small balances across several banks can add up to a breach even when no single account looks significant. Include savings accounts, interest-paying current accounts, any bonds, and peer-to-peer returns. Leave out ISA interest and Premium Bond prizes, because those never count.

Compare the total to your allowance. Work out your tax band first, remembering that the interest itself stacks on top of your other income and can push you up a band. Then set your total interest against the right allowance: £1,000 if you are a basic-rate taxpayer, £500 if higher-rate, nothing if additional-rate. Anything above that line is taxable.

Check your tax code. If HMRC has already estimated savings interest for you, it will show up as a deduction in your tax code, which you can see on a coding notice or in your payslip breakdown. A code that has dropped below the standard 1257L without an obvious reason often points to a savings-interest adjustment.

Use your HMRC personal tax account. The online personal tax account on the GOV.UK website is where HMRC shows the interest figures it holds for you and how it has treated them. It is the definitive view of what HMRC thinks you earned, and it is worth a look if a coding change appears and you want to see the numbers behind it.

How to Stay Within the PSA (or Reduce the Tax)

Breaching the allowance is not a disaster, and it is not a reason to stop saving. It just means part of your interest is taxed, often at a modest amount. There are several ways to keep more of that interest, and the order below is roughly the order most people will find useful. None of this is advice to buy a particular product; it is a map of the options so you can see which fit your situation.

Use your ISA allowance first. This is the most effective step for most savers. You can pay up to £20,000 into ISAs in the 2026/27 tax year, and interest earned inside a cash ISA is completely outside the PSA: it never counts towards your allowance, no matter how large it grows. Moving savings into a cash ISA shrinks the taxable interest sitting in ordinary accounts, which is exactly what keeps you under the line. There is a timing reason to act sooner rather than later. The 2026/27 year is the last full year of the £20,000 cash ISA limit for those under 65. From 6 April 2027 the cash ISA limit falls to £12,000 for under-65s, although the overall £20,000 ISA allowance across all types is unchanged and those aged 65 and over keep the full £20,000 in cash. If you have cash you want to shelter, filling a cash ISA this year locks in more tax-free room than you will get next year. For how cash ISAs compare with the other tax wrappers, our guide to ISA vs SIPP vs GIA sets out the differences.

Split savings between partners. Each person has their own Personal Savings Allowance, so a couple has two allowances to use. If one partner pays tax at a lower rate, holding more of the joint savings in their name can mean a larger allowance and a lower tax rate on any excess. A non-taxpayer or basic-rate partner with the £1,000 allowance can shelter far more interest than a higher-rate partner with only £500. Joint accounts are treated as split 50/50 for tax, so each of you is taxed on half the interest, which is worth bearing in mind when you decide whose name an account sits in.

Consider Premium Bonds. Premium Bond prizes are tax-free and sit entirely outside the PSA, so they can be useful once you have used up your allowance and your ISA. The NS&I prize-fund rate rises to 3.80% from the July 2026 draw, having been 3.30% up to the June draw. That is below the best savings accounts, so Premium Bonds are not about chasing the highest return. They suit people who have already filled their tax-free options and want somewhere to hold cash without adding to their taxable interest, which makes them most attractive to higher and additional-rate taxpayers. The return is also a matter of chance rather than a guaranteed rate. We weigh up the trade-offs in detail in are Premium Bonds worth it.

Time fixed-rate bonds carefully. Some fixed-rate bonds pay all their interest at maturity rather than each year, and for tax purposes the interest usually counts in the year it becomes available to you. With a multi-year bond that pays out at the end, that can mean a single large lump of interest landing in one tax year, which is more likely to breach your allowance than the same amount spread out. Choosing the maturity date, or picking a bond that pays interest annually, gives you some control over which tax year the interest falls into. This is fine-tuning rather than a headline move, and it matters most for larger sums.

Look at a stocks and shares ISA for long-term money. For money you will not need for several years, a stocks and shares ISA shelters returns from tax in the same way a cash ISA does, and it shares the same £20,000 annual allowance. The trade-off is risk: the value of investments can fall as well as rise, and you could get back less than you put in, so this is not a home for cash you might need soon or for an emergency fund. For long-term savings, though, it removes the question of the PSA entirely, because nothing inside it is taxed. If you are new to investing, our explainer on index funds is a sensible starting point for understanding low-cost, diversified options.

The Starting Rate for Savings: An Extra £5,000 Allowance Most People Miss

There is a second, less well-known allowance that can stack on top of the PSA, and it can be worth far more. It is called the starting rate for savings, and it lets you earn up to £5,000 of savings interest taxed at 0%, on top of your £1,000 PSA. Combine the two and a person in the right circumstances can receive a substantial amount of interest with no tax at all.

The catch is that it is aimed squarely at people with low non-savings income. The full £5,000 is only available if your non-savings income, mainly earnings and pensions, is at or below the £12,570 personal allowance. Above that, the starting rate tapers: every £1 of non-savings income over £12,570 reduces it by £1. So once your non-savings income reaches £17,570, the starting rate has tapered away to nothing. Between those two points you get a partial band.

That design means it tends to benefit low earners, some retirees living mainly off savings before their pensions ramp up, and students with little or no earned income. If your wages or pension are modest but you hold a meaningful amount in savings, it is well worth checking whether the starting rate applies to you, because it is the kind of allowance that goes unclaimed simply because people have never heard of it.

Scottish Taxpayers

Scotland sets its own income tax bands on earnings, with more bands and different thresholds than the rest of the UK. That leads a lot of people to assume their savings allowance follows the Scottish bands too. It does not, and getting this wrong can cost you the wrong allowance.

Savings and dividend income are taxed on a UK-wide basis, which means your Personal Savings Allowance is decided by the rest-of-UK income tax bands, not the Scottish ones. The £1,000 allowance applies up to £50,270 of income, and it drops to £500 above that, using the same thresholds as a taxpayer in England. The Scottish bands govern the tax on your salary and pension, but they do not change which PSA band you sit in.

The practical upshot is reassuring. A Scottish taxpayer whose total income is under £50,270 keeps the full £1,000 Personal Savings Allowance, even if they are paying the Scottish intermediate or higher rate on their earnings. Your Scottish tax band might suggest you are a higher-rate payer for the purposes of your salary, but for your savings interest what counts is whether your income crosses the £50,270 UK threshold. Keep the two systems separate in your head and the allowance is more generous than it first appears.

Seeing the Whole Picture Before the Tax Year Ends

The hardest part of staying within the PSA is not the rules, it is the visibility. Most people hold savings across more than one account: an easy-access pot here, a fixed-rate bond there, a bit of interest on the current account, perhaps a balance left over from a switching offer. Each looks small on its own. Added together they can quietly cross the allowance, and because no single account looks alarming, the breach is easy to miss until HMRC points it out a year later.

This is where seeing everything in one place earns its keep. Endute brings your savings balances together across all your accounts, so you can look at your total rather than guessing from memory. With the full figure in front of you, it is straightforward to judge whether your savings are nearing the level where the interest would breach your PSA, and to act before the tax year ends, by moving money into an ISA, shifting some to a lower-rate partner, or topping up Premium Bonds, while there is still time to make a difference. You can see how this works on our features page.

The Bottom Line

The Personal Savings Allowance has not changed since 2016, but the world around it has. Higher interest rates mean balances that once sat comfortably under the line now produce enough interest to be taxed, and HMRC sees it all automatically. The allowance is still generous, though, especially once you factor in ISAs, the starting rate for savings, and a partner's allowance alongside your own. A short check each year, adding up your interest and setting it against the right allowance, is usually enough to stay ahead of any surprise. Know which band you are in, use your tax-free wrappers, and keep an eye on the total rather than the individual accounts. Do that, and a coding-notice letter stops being a shock and becomes something you saw coming.

Frequently Asked Questions

What is the personal savings allowance?

It is the amount of interest you can earn each tax year before any tax is charged on it. The allowance depends on your income tax band: £1,000 for basic-rate taxpayers, £500 for higher-rate taxpayers, and nothing for additional-rate taxpayers. It applies on top of your £12,570 personal allowance and has stayed at these levels since 2016.

How much savings interest can I earn tax-free?

A basic-rate taxpayer can earn £1,000 of interest tax-free, and a higher-rate taxpayer £500, through the Personal Savings Allowance. Some people on low non-savings income can earn up to £5,000 more tax-free through the starting rate for savings. On top of that, any interest earned inside an ISA is always tax-free and does not count towards these limits.

Do I pay tax on savings interest?

Only on interest above your allowance. If your total taxable interest stays within your Personal Savings Allowance, you pay no tax on it. Anything above the allowance is taxed at your normal income tax rate, so 20% for a basic-rate taxpayer, 40% for higher-rate and 45% for additional-rate. Interest inside an ISA and Premium Bond prizes are never taxed.

What happens if I exceed the personal savings allowance?

Your bank reports the interest it paid you to HMRC automatically, and HMRC works out the tax due on the amount above your allowance. For most people it is collected by adjusting their tax code for the following year, so a little more tax comes out of their pay rather than arriving as a separate bill. People who file a Self Assessment return pay it through that instead.

How much can I have in savings before I pay tax?

It depends on the interest rate, not just the balance. At around 4.5%, a basic-rate taxpayer would breach the £1,000 allowance with roughly £22,000 of savings, and a higher-rate taxpayer would breach the £500 allowance with around £11,000. If rates are lower, you can hold more before crossing the line. Money held in ISAs does not count at all, so it does not affect this calculation.

Is ISA interest included in the personal savings allowance?

No. Interest earned inside any ISA is tax-free and sits completely outside the Personal Savings Allowance. It never uses up any part of your £1,000 or £500, no matter how much interest the ISA produces. That is why moving savings into a cash ISA is one of the most effective ways to keep your taxable interest below the allowance.
