Important information: As investment values can go down as well as up, you may not get back all of the money you invest. Currency changes affect international investments, and this can decrease their value in sterling. If you’re unsure if an investment account is right for you, please speak to an authorised financial adviser. Tax treatment depends on your individual circumstances and may be subject to change in the future.

Tax FAQs

A tax return is a document submitted to HMRC that reports your total income, expenses, savings interest, investments, and other financial information for the tax year. HMRC uses this information to determine whether you’ve paid the right amount of tax or if you need to pay more.

Many people in the UK have their tax collected automatically through PAYE and do not need to file a Self Assessment tax return.

You generally won’t need to file if:

  • You are an employee and your income tax is deducted through PAYE
  • You do not have other sources of income above specific thresholds (e.g. savings interest below your Personal Savings Allowance, or rental/side‑income below £1,000)

You may need to file a Self Assessment tax return if:

  • You earn rental income from property
  • You earn more than £10,000 from savings, investments, or dividends
  • You’re self‑employed or earn more than £1,000 from a 'side hustle'
  • Your income exceeds £100,000
  • You receive more than £2,500 in untaxed income (e.g. tips, commission)
  • You have capital gains above the annual CGT allowance
  • You or your partner earn over £60,000 and receive Child Benefit

If your circumstances change and you no longer need to file a tax return, make sure you inform HMRC as soon as possible via the GOV.UK service.

Yes, in some cases HMRC will automatically refund overpaid tax, such as if you're employed, and your PAYE tax has been calculated incorrectly.

However, not all refunds are issued automatically. You may need to submit a claim or file a tax return if:

You’re self-employed
You claim work‑related expenses
You have untaxed income
Your tax position cannot be verified through PAYE alone

Since April 2024, many taxpayers must now actively claim refunds through their Personal Tax Account or by submitting a tax return.

For more information on tax overpayments and underpayments, visit GOV.UK.

Recent government announcements include several key tax changes affecting individuals and investors from 2026 onwards:

Dividend tax - From April 2026 dividend tax rates will rise by 2% increasing to:

  • 10.75% from 8.75% (basic rate)
  • 35.75% from 33.75% (higher rate)

There is no increase for additional rate taxpayers, who will continue to pay 39.35%

Making Tax Digital (MTD) - From April 2026, landlords and self‑employed individuals with income over £50,000 (£30,000 from April 2027), must follow new digital reporting rules under Making Tax Digital for Income Tax.

The rules require keeping digital records and sending HMRC quarterly updates on your income and expenses via compatible software.

Income tax and National Insurance thresholds - There are no changes to the rates, however Income tax bands will remain frozen until at least 2031. This means that even if your income gradually increases, a greater proportion of your earnings may fall into a higher tax band, meaning more of your income is taxed.

Savings interest is taxable. However, whether you pay any tax on your savings all comes down to how much interest you earn and the rate of income tax you pay, as this determines your Personal Savings Allowance (PSA) - which is the amount of savings interest you can earn tax-free each tax year.
 
Below is the amount of interest you can earn on savings without paying tax:
 
Basic rate taxpayer - up to £1,000
Higher rate taxpayer - Up to £500
Additional rate taxpayer - No savings interest allowance

Low-income earners may also qualify for the Starting Rate for Savings, which allows you to earn up to £5,000 in interest tax-free. This is an additional tax-free allowance, separate from the PSA, and it depends on your other taxable income, such as earnings from work or a pension.

If your interest stays within your PSA, you won’t pay tax on it. But if it exceeds your allowance, HMRC will usually collect any tax due automatically (through your tax code), although some people may need to report it through Self Assessment.

Interest earned from ISAs is tax-free and does not count towards your PSA.
