Personal Savings Allowance (PSA) in the UK: Complete Guide

The Personal Savings Allowance (PSA) lets UK taxpayers earn a certain amount of interest each year tax-free. How much you get depends on your Income Tax band, and not everyone qualifies.

This guide explains how the Personal Savings Allowance works, how much interest you can earn without paying tax, what counts as savings income, and what to do if you go over your allowance.

Key points

• Your Personal Savings Allowance depends on your tax band 💸
  The amount of interest you can earn tax-free isn’t fixed. Basic rate taxpayers get £1,000, higher rate taxpayers get £500, and additional rate taxpayers get none.
• Small income changes can affect how your savings are taxed 📈
  Moving into a higher tax band can reduce or remove your savings allowance too. Even bonuses, freelance income, or rental earnings can push you into a less favourable position.
• Not all returns are treated the same 🏦
  The allowance applies to interest from savings accounts, bonds, and similar products. Dividends from shares are taxed separately under different rules, so it’s important to understand what type of income you’re earning.
• There are multiple ways to legally reduce tax on savings 🧠
  Using ISAs, splitting savings with a partner, managing your income, and timing the interest payout can all help you stay within your allowance and minimise tax.
• Staying on top of your tax position is easier with automation ⚙️
  Tracking interest, income, and allowances throughout the year can get complicated fast. With ANNA, everything is handled in the background, from real-time tax tracking to automatic Self Assessment and smart tax pots, so you always know where you stand.

What is the Personal Savings Allowance?

The Personal Savings Allowance is the amount of interest you can earn on your savings each tax year without paying Income Tax on it. It was introduced by HMRC to simplify the taxation of savings income.

Before the PSA, banks used to deduct tax at source. Now, most interest is paid gross – meaning without tax taken off – and it’s your responsibility to check whether any tax is due.

How much interest is tax-free?

Your Income Tax band determines how much tax-free interest you get. The Income Tax band is based on your total taxable income. As your total taxable income increases, the amount of interest you can earn tax-free decreases.

It works like this:

• If you’re a basic rate taxpayer (20%), you can earn up to £1,000 in savings interest each tax year without paying tax on it
• If you’re a higher rate taxpayer (40%), your allowance is £500
• If you’re in the additional rate band (45%), you don’t get a Personal Savings Allowance, so all savings interest is taxable

This shift doesn’t just happen with salary increases – it can also be triggered by bonuses, rental income, or profits from self employment.

Because of this, even relatively small changes in income can have a knock-on effect on how your savings are taxed, making it important to consider your full financial picture rather than looking at savings in isolation.

What does PSA apply to?

The Personal Savings Allowance applies to most types of interest you earn from holding money, rather than investing in shares. This includes interest from everyday bank and building society accounts, as well as savings accounts and fixed-rate bonds where your money is held for a set period.

It can also cover distributions from certain investment funds where the return is treated as interest rather than dividends, as well as interest earned through credit unions.

What’s important is the type of return you receive. If it’s classified as interest, it usually falls within the scope of the PSA. If it’s a dividend from shares, it doesn’t – dividends are taxed separately under the Dividend Allowance, with their own rates and thresholds.

The starting rate for savings

In addition to the Personal Savings Allowance, there is another, often overlooked, relief called the starting rate for savings. This can provide up to £5,000 of additional tax-free interest, but it’s only available to people with low non-savings income.

The way it works is gradual: if your income from sources like wages or business profits is below the Personal Allowance threshold, you may be able to use the full £5,000 starting rate band.

As your non-savings income increases above that level, the allowance is reduced on a pound-for-pound basis. Once your non-savings income reaches £17,570, the starting rate is no longer available.

For those who qualify, this can significantly increase the total amount of interest earned tax-free when combined with the Personal Savings Allowance. However, because eligibility depends on income levels, it’s most relevant to individuals with modest earnings and higher savings.

Do you need to report savings interest?

In most cases, savings interest is handled automatically. Banks and financial institutions report the interest you earn directly to HMRC, which then uses this information to calculate whether any tax is due. If necessary, HMRC will usually collect the tax by adjusting your tax code, so you don’t need to take any immediate action.

That said, there are situations where you are responsible for reporting it yourself.

If you complete a Self Assessment tax return, you’ll need to include your total savings interest for the year. You may also need to declare it if your savings income is particularly high, or if HMRC specifically asks you to provide the details.

Even when reporting isn’t required, it’s still worth keeping track of how much interest you’re earning across all accounts. This helps you stay within your allowances where possible and avoid unexpected tax adjustments later on.

How to reduce tax on your savings

If your savings are close to or above your Personal Savings Allowance, there are several legitimate ways to reduce the amount of tax you pay on interest.

Most of these strategies focus on either shielding your savings from tax or making better use of available allowances.

Use an Individual Savings Account (ISA)

One of the most effective ways to protect your savings from tax is to use an Individual Savings Account (ISA). Any interest earned inside an ISA is completely tax-free and doesn’t count towards your Personal Savings Allowance.

This means you can hold cash savings, earn interest, and withdraw money without worrying about tax reporting or thresholds.

ISAs are particularly useful if you expect to earn significant interest or if interest rates rise, as they remove the tax issue rather than just reducing it.

The ISA allowance for the 2026/27 tax year is £20,000 per person. The limit resets annually on 6 April, and unused allowances don’t carry over.

Split savings with a partner

If you’re married or in a civil partnership, you can often reduce your tax bill by distributing savings. Since each person has their own Personal Savings Allowance, holding savings in the name of the lower-earning partner can help maximise the combined tax-free amount.

For example, if one partner is a basic rate taxpayer and the other is a higher rate taxpayer, shifting more savings into the basic rate taxpayer’s name can increase the total amount of interest earned tax-free between you.

For joint accounts, HMRC generally taxes interest 50:50 by default, but couples can choose a different split if the actual beneficial ownership is different. The key is that ownership of the money must genuinely reflect how the savings are held in practice.

Manage the timing of your income and interest

The timing of when you receive income can affect how much tax you pay and which allowances you stay within.

Most types of income, including bonuses, dividends, and freelance earnings, are taxed in the tax year they are received. This means even a one-off payment near the end of the tax year can push you into a higher tax band or reduce allowances for that year.

Savings interest is also taxed based on when it’s paid or credited to your account, not when it originally builds up. This is particularly relevant for fixed-term savings accounts, where a large amount of interest may be paid in a single tax year when the account matures.

Because of this, timing matters. Receiving multiple sources of income in the same tax year can push you over key thresholds, while spreading income or interest across different tax years may help you stay within lower tax bands or maximise allowances.

In practice, being aware of when income is likely to land gives you more control over your tax position, especially if you are close to a threshold or expect fluctuations in earnings.

How ANNA can help with your tax obligations

Understanding allowances like the Personal Savings Allowance is only part of the picture. The real challenge is how these rules interact with your wider income and tax position throughout the year.
