Tax-Free Allowances You Should Know About in the UK

Beyond your personal allowance, the UK tax system gives you several other tax-free allowances that can save you hundreds of pounds a year — if you know where to look and claim them. This guide explains all the tax-free allowances you should know about, with real numbers and practical examples.

Your Personal Allowance: The Biggest Tax-Free Slice

The personal allowance is the amount of income you can earn tax-free each year. For the 2025/26 tax year, that's £12,570 in the UK. Whatever you earn below this threshold is yours to keep; tax starts only on income above it.

Read our full guide to the personal allowance for more detail, but here's the key: if you're a basic rate taxpayer (earning between £12,571 and £50,270), you pay 20% tax on every pound above £12,570. If you're a higher rate taxpayer (earning above £50,271), you pay 40% on income in that band. Your personal allowance doesn't disappear — it just matters differently depending on your tax bracket.

Your tax code on your payslip (usually something like 1257L) tells your employer how much of your personal allowance to apply to your salary. If your code is wrong, you're overpaying or underpaying tax every month. Check it against HMRC's tax code guidance if it looks unusual.

The Other Tax-Free Allowances You're Missing

Most people forget they have MORE tax-free allowances beyond the personal allowance. Here are the big ones:

Savings Interest Allowance

If you earn interest on savings, you get a tax-free slice of that interest depending on your tax bracket:

Basic rate taxpayers: £1,000 tax-free interest (2025/26)
Higher rate taxpayers: £500 tax-free interest
Additional rate taxpayers: £0 (no allowance)

This means a basic rate earner can earn up to £1,000 in interest without paying a penny of tax. At current savings rates (around 4–5%), that's about £20,000–£25,000 saved in an easy-access account. Higher rate taxpayers get £500, which is roughly £10,000–£12,500 in savings.

Dividend Allowance

Dividends (income from shares or business profits) have their own tax-free zone:

Everyone: £500 tax-free dividends per year (2025/26)

Above £500, you pay dividend tax at 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate). Learn more about how dividend tax works and how to calculate your liability.

Capital Gains Allowance

When you sell an asset (shares, property, artwork) at a profit, you owe capital gains tax on the profit — but only above your annual exemption. For 2025/26, that's:

£3,000 tax-free capital gains per year

This applies to everyone, regardless of tax band. Gains above that are taxed at 10% or 20% depending on whether the asset is a residential property and your income level.

Trading Allowance (Self-Employment)

If you're self-employed, a freelancer, or have side income, the trading allowance is a game-changer. You can earn up to £1,000 tax-free from trading income each tax year without deducting expenses. If you earn less than £1,000, you claim the full amount. If you earn more, you either claim the £1,000 or claim your actual expenses — whichever is bigger.

This matters because it's simpler than keeping meticulous records for very small side incomes. Earned £600 from freelance work? You get £1,000 tax-free. Earned £2,000? Use the trading allowance (£1,000 free) or your actual expenses (maybe £300), whichever saves more tax.

Marriage Allowance

If you're in a relationship and one partner earns significantly less than the personal allowance while the other is a basic rate taxpayer, the marriage allowance can transfer unused allowance to the higher earner. This saves up to £252 per year and can be backdated 4 years, so it's definitely worth checking. See if you're eligible on Gov.uk.

How Tax Bands Make Your Allowances Count

To understand why all these allowances matter, you need to see how UK tax bands work. For more detail, read our guide to income tax bands and rates.

Here's the short version: the UK uses a progressive tax system. Your income is taxed in layers:

£0–£12,570: 0% (personal allowance)
£12,571–£50,270: 20% (basic rate)
£50,271–£125,140: 40% (higher rate)
£125,141+: 45% (additional rate)

Only the income within each band is taxed at that rate. Earn £60,000? You don't pay 40% on all of it — you pay:

0% on the first £12,570 (personal allowance)
20% on £12,571–£50,270 (£37,699 × 20% = £7,540)
40% on £50,271–£60,000 (£9,730 × 40% = £3,892)
Total tax: £11,432 (effective rate: 19%)

That's why knowing all your allowances matters. Each one is a slice of income you don't pay tax on, which directly reduces the amount taxed at your marginal rate.

Tax-Free Allowances by Your Situation

If You're an Employee

Your main allowance is the personal allowance on your payslip (minus National Insurance contributions, which are separate). You also get the savings interest allowance if you earn interest on savings and the dividend allowance if you receive dividends.

If you work from home, you might be able to claim £6 per week (£312 per year) working-from-home relief — ask your employer about this. It's not a tax-free allowance in the same way, but it's tax relief that reduces your taxable income.

If You're Self-Employed

Your main tax-free allowance is the trading allowance of £1,000. File your tax return with your gross trading income, then claim the £1,000 allowance on your Self-Assessment return (or claim your actual allowable expenses if they're higher).

You also get your personal allowance (£12,570) on top of this, the savings interest allowance, and the dividend allowance if you receive dividends from your business.

Make sure you understand Making Tax Digital if you're self-employed — you'll need digital records and quarterly reporting from April 2024 onwards (with a transition period for smaller businesses).

If You're a Saver or Investor

The savings interest allowance (£1,000 for basic rate, £500 for higher rate) and the dividend allowance (£500 for everyone) are your friends. If you have multiple savings accounts or receive dividends from shares, add up the interest and dividends to see if you're using your full allowance.

Maximise tax-free saving by using an ISA (Individual Savings Account) — you can save up to £20,000 per year in an ISA with no tax on any interest or gains. That's a far better use of your allowance than letting interest sit in a standard savings account.

If You've Got Multiple Income Sources

If you earn from employment, self-employment, rental income, dividends, and savings interest, each has its own rules and allowances:

Employment: personal allowance + savings interest + dividends + capital gains allowances
Self-employment: trading allowance (£1,000) + personal allowance + savings + dividends
Rental income: personal allowance + savings + dividends + capital gains (but rental income has no separate allowance — you can only claim expenses)
Dividends: dividend allowance (£500) applies once, across all sources
Savings interest: savings allowance applies once, across all sources
Capital gains: capital gains allowance (£3,000) applies once, across all sources

Add it all up at year-end when you file your tax return and work out what you owe.

Tax-Free Allowance Mistakes to Avoid

Forgetting to claim the trading allowance — if you're self-employed and your profit is under £1,000, you still need to file a Self-Assessment return and claim the allowance. It won't happen automatically.

Not tracking savings across banks — your savings interest allowance applies to interest from all your savings accounts combined. If you have £5,000 in Bank A at 4% (£200 interest) and £5,000 in Bank B at 4% (£200 interest), that's £400 total interest. If you're a basic rate taxpayer, you get £1,000 tax-free, so you're fine. But if you have multiple accounts, add them up to be sure.

Ignoring dividends from your business or ISA — if you own shares (including your own business) and receive dividends, the £500 dividend allowance applies once per year across all dividend income. Know your total dividend income to see if you're in the allowance or paying dividend tax.

Missing the marriage allowance — if one partner earns under £12,570 and the other is a basic rate taxpayer, applying for marriage allowance is a 5-minute job online and it saves up to £252 per year. It can be backdated 4 years, so even if you missed a previous year, you can reclaim.

Not keeping records for the trading allowance — even though the trading allowance is £1,000 tax-free without expenses, HMRC still asks for records of your actual income and expenses if they enquire. Keep your bank statements and receipts even if you're claiming the allowance.

Frequently Asked Questions

Q: Can I have a personal allowance and a trading allowance? A: Yes. If you're self-employed, you get both. Your personal allowance (£12,570) covers employment or other income, and your trading allowance (£1,000) covers self-employment income. They don't overlap; you use each allowance on its relevant income.

Q: Do I get a tax-free allowance if I'm retired? A: Yes, everyone gets the personal allowance (£12,570) no matter your age. You also get the savings interest allowance and the dividend allowance. The state pension is partly covered by the personal allowance — if you receive the state pension, your income is usually below the basic rate threshold, so you may not owe tax at all.

Q: What happens if I have interest from multiple savings accounts? A: Your savings interest allowance (£1,000 for basic rate, £500 for higher rate) applies to interest from all savings combined. Add up the interest across every account and compare to your allowance. You only pay tax on interest above the allowance.

Q: Is the dividend allowance the same for everyone? A: Yes, everyone gets £500 of tax-free dividends per year, regardless of your tax band. Above that, you pay dividend tax at rates depending on your bracket: 8.75% (basic rate), 33.75% (higher rate), or 39.35% (additional rate).

Q: Can I choose not to use my allowances? A: You don't usually have to "choose" — HMRC applies allowances automatically when you file your tax return or your employer's PAYE system applies them. But if you prefer to pay tax on some of your allowance (e.g., to build pension contributions), you can ask HMRC in writing. This is rare and usually only applies to high earners optimising pension relief.

Q: What if my allowance changes mid-year? A: Tax allowances are set per tax year (6 April to 5 April). They don't change mid-year, but they do change each April. If you have a significant life event (marriage, birth, moving to/from the UK), contact HMRC to adjust your tax code if needed.

Q: How long should I keep records to claim allowances? A: HMRC can enquire into your tax affairs up to 4 years back (6 years if they suspect carelessness, 20 years for fraud or evasion). Keep bank statements, receipts, invoices, and payslips for at least 4 years, but 6 is safer.

Q: Can I transfer my unused capital gains allowance to my partner? A: No. Your capital gains allowance (£3,000) only applies to your own gains. Unlike the marriage allowance, there's no transfer mechanism for unused capital gains or dividend allowances.

Your Next Steps

Now you know the tax-free allowances available to you. The next step is to work out your actual tax liability and see where you can optimize. Use our tax calculator to plug in your income and see exactly how much tax you owe across different scenarios.

If you're self-employed, make sure you understand how to calculate your trading allowance and when to claim it versus actual expenses. If you're a saver, review the dividend tax and allowance to make sure you're not overpaying on your investments.

And if you've got a complex tax situation — multiple income sources, a business, significant investments — consider a conversation with an accountant or tax advisor. The allowances are worth thousands of pounds a year, and getting them right pays for itself.
