How to claim a personal tax refund when leaving the UK

When you leave the UK permanently, you may be owed a tax refund if you've paid more income tax than you owe for the tax year you're leaving. HMRC (Her Majesty's Revenue and Customs) will calculate what you're owed based on the months you worked in the UK during that tax year. You don't automatically receive this money — you need to contact HMRC and provide proof of your departure and your new address abroad.

The refund process depends on whether you left mid-tax-year or at the end of one, and whether you're a British citizen, EU citizen, or from another country. Processing times vary, but most refunds take 4 to 8 weeks once HMRC has all the information they need.

Key Takeaways

  • Contact HMRC within the tax year you leave or shortly after to report your departure and request a refund calculation.
  • You'll need to provide your departure date, your new address outside the UK, and proof of your move (such as a visa, employment contract, or tenancy agreement abroad).
  • HMRC calculates refunds based on the months you were a UK resident and paid tax; you only receive money if you overpaid.
  • Refunds are normally paid to a UK bank account, but you can request payment to an overseas account if you provide the correct details.
  • If you left without notifying HMRC, you can still claim a refund up to four years after the end of the tax year in which you left.

When you're may have access to to a refund

You're may have access to to a refund if you paid more income tax than you owed during the tax year you left the UK. This commonly happens when you worked for only part of the year — for example, if you left in June, you were only a UK resident for nine months, so your personal allowance (the amount you can earn tax-free) is reduced proportionally.

If your employer deducted tax under PAYE (Pay As You Earn) based on a full year's work, but you only worked nine months, you've overpaid. HMRC recalculates your tax liability based on your actual time in the UK and refunds the difference.

You won't receive a refund if you owed more tax than you paid, or if your tax bill exactly matched what was deducted. You also won't receive a refund if you were not a UK resident for tax purposes during the year — this depends on your visa status and how many days you spent in the UK, not simply on when you physically left.

Notifying HMRC of your departure

Contact HMRC as soon as you know you're leaving the UK. You can do this before you leave or within a reasonable time after. The sooner you notify them, the sooner they can calculate your refund. Use the Self Assessment online account if you have one, or call HMRC's Income Tax helpline on 0300 200 3300 (from outside the UK: +44 300 200 3300).

When you contact HMRC, have ready: your National Insurance number, your departure date, your new address outside the UK, and the country you're moving to. If you're moving for work, have your employment contract or job offer letter. If you're moving to study, have your university acceptance letter. If you're moving to join family, have proof of your relationship and their address.

HMRC will ask whether you're leaving permanently or temporarily. If you're leaving for more than a few years, you're treated as a non-resident for tax purposes. If you're leaving for a short secondment or sabbatical and plan to return, the rules are different — tell HMRC your expected return date.

Documents you need to provide

HMRC requires proof that you've left the UK and are now resident elsewhere. The documents that work depend on your situation. If you're moving for work, provide your employment contract showing your start date abroad and your UK end date. If you're moving to study, provide your university enrolment letter or acceptance letter with the start date. If you're moving to join family, provide a tenancy agreement or property deed in your new country, or a letter from a family member confirming your address.

You'll also need to show your departure from the UK. A plane ticket, ferry ticket, or shipping document with your name and travel date works. Some people provide a letter from their new employer or university confirming their arrival date. If you left several months ago and don't have a ticket, a dated utility bill or bank statement from your new address, combined with your employment contract or tenancy agreement, is usually sufficient.

Keep copies of everything you send to HMRC. If your refund is delayed or HMRC asks follow-up questions, you'll need to refer back to what you submitted.

How HMRC calculates your refund

HMRC works out your tax refund by calculating your personal allowance for the months you were a UK resident. The standard personal allowance for the 2024–25 tax year is £12,570, but this is divided by 12 and multiplied by the number of months you were resident.

For example, if you left on 30 June, you were resident for six months (July to December of the previous tax year, or January to June of the current one, depending on when you left). Your personal allowance for that period would be roughly £6,285. HMRC then calculates the tax you should have paid on your actual income during those months and compares it to what was deducted. The difference is your refund.

This calculation also takes into account any other tax reliefs or allowances you're may have access to to, such as marriage allowance or trading allowances if you're self-employed. If you were self-employed or had multiple jobs, the calculation is more complex, and HMRC may ask for your Self Assessment tax return for that year.

Where your refund will be paid

HMRC normally pays refunds to the UK bank account where your salary was paid. If you've closed that account or no longer have access to it, tell HMRC your new account details. You can provide an overseas bank account, but include the IBAN (International Bank Account Number) and SWIFT code so the money reaches the right place.

Refunds to UK accounts usually arrive within 4 to 8 weeks of HMRC processing your claim. Refunds to overseas accounts may take longer — up to 10 working days for the money to leave the UK, plus additional time for your overseas bank to receive and process it. Some overseas banks charge a fee for receiving international transfers; check with your bank before providing your details.

If you're moving to an EU country, Switzerland, or another country with a reciprocal tax agreement with the UK, HMRC can sometimes arrange payment through the tax authority in your new country. Ask HMRC whether this is an option for you.

If you left without telling HMRC

If you left the UK without notifying HMRC and didn't claim a refund at the time, you can still do so. HMRC allows you to claim a refund up to four years after the end of the tax year in which you left. For example, if you left in June 2021, you can claim a refund for the 2020–21 tax year until 5 April 2025.

Contact HMRC with the same information as above: your departure date, your new address, and proof of your move. Explain that you're claiming late and provide the same documents. HMRC will still calculate your refund based on the months you were resident, regardless of how long ago you left.

If more than four years have passed, you cannot claim a refund through the normal route. In rare cases, HMRC may consider a claim outside this time limit if you have a good reason for the delay — for example, if you were abroad and had no way to contact HMRC. Contact HMRC directly to discuss your situation.

Frequently Asked Questions

Do I need to file a Self Assessment tax return to get my refund?

Not always. If you were employed and your only income was your salary, HMRC can calculate your refund without a tax return. However, if you were self-employed, had multiple jobs, or received other income (rental income, dividends, interest), HMRC will ask you to file a Self Assessment return for the year you left. You can file this online through your Self Assessment account.

What if I'm moving to a country with no tax treaty with the UK?

You can still claim a refund. The tax treaty affects whether you pay tax in the UK or your new country on future income, but it doesn't change your right to a refund for overpaid UK tax in the year you left. Provide HMRC with your new address and they'll process your claim as normal.

Can I claim a refund if I'm moving abroad temporarily?

Yes, but HMRC needs to know your expected return date. If you're on a two-year work contract abroad and plan to return to the UK after, you may still be treated as a UK resident for tax purposes, depending on your circumstances. Tell HMRC your situation and they'll advise whether you're may have access to to a refund for the year you left.

How long does it take to receive my refund?

Most refunds are paid within 4 to 8 weeks of HMRC receiving your complete claim. If you're paying to an overseas account, add 10 to 15 working days for the international transfer. If HMRC needs more information from you, processing will be delayed until you provide it.

What if HMRC says I owe tax instead of a refund?

If you underpaid tax during the year you left, HMRC will tell you what you owe. You can pay this by bank transfer, debit card, or credit card. HMRC will provide a payment reference. If you disagree with the calculation, you can ask HMRC to review it or appeal within 30 days of the notice.
