Don't close your bank account before leaving the UK: What to do about tax refunds and pensions
Tickets booked, house rented out, bank card canceled the same day - three months later, HMRC sent a check for a few hundred pounds to the old address in the UK, and the money could not enter any account that was still active. This is the most common and most unfortunate loss when leaving the UK.
The money to be handled before leaving is actually divided into three lines: refund, account, and pension . Each has its own timeline, and if the order is messed up, you will have to go around again.
How to get a tax refund when leaving the UK? Two conditions for Form P85
UK income tax is estimated based on annual income and deducted monthly. You left in September, but the system deducted tax assuming "you would work until April 5th of the next year", and you need to actively claim back the over-deducted amount.
Tools are P85 (Get your Income Tax right if you're leaving the UK). GOV.UK clearly states: applies to those who have lived and worked in the UK, left and may not return, or will work full-time overseas for at least one complete tax year.
Two operational details are most easily overlooked: , you can only print and mail it out before leaving the UK, online declaration is only open to those who have already left; when you leave your job, the P45 you receive should have the 2nd and 3rd copies submitted together.
HMRC clearly states that it does not bear the cost of converting refunds into foreign currency or transferring them overseas. Checks will be sent to the current address registered in the system. Therefore, do not close your UK bank account before the tax refund is received.
Can ISA and bank accounts remain after leaving the UK?
The ISA rules state: after becoming a non-resident, you cannot make further contributions to it starting from the next tax year , but the account can remain open, and the money inside remains tax-free in the UK. You need to inform the ISA provider that you have moved away; don't wait for them to find out.
Regular current accounts depend on the bank's policy. Many banks do not accept regular accounts with overseas addresses, and will require converting to an international account or closing it. The safe approach is to keep an account that can still receive money, and handle the account after all tax refunds, pension reconciliations, and deposit returns are completed.
6 Items in the Timeline Before and After Departure (Recommended to Take a Screenshot)
| Matters | When to handle | Key Points |
|---|---|---|
| Refund | Mail before departure / Online after departure | Attach Part P45, Sections 2 and 3 |
| Bank Account | Withdraw funds after the tax refund is received | HMRC does not pay for currency exchange/cross-border fees |
| ISA | Starting from the next tax year, | Stop contributions, account can be retained |
| Company Pension | Record immediately upon leaving | Retained Institution Name and Policy Number |
| NI Make up payment | The earlier, the better | Form CF83, first read NI38 |
| Pension Transfer Abroad | Don't Rush to Handle | Conditions Not Met Deduct 25% |
Can the UK pensioner still receive the pension? The 57-year-old and 25% barrier
First, the conclusion: The money in your workplace pension is yours, and it won't disappear when you leave, it can stay in the UK forever. The earliest age to withdraw is 55 years old, increasing to 57 years old starting from April 6, 2028 (according to Finance Act 2022, section 10). If you have changed several jobs or forgotten which institution holds your pension, use GOV.UK's Pension Tracing Service to search by employer's name.
Many people want to "just transfer the entire amount overseas." This step needs to be very careful: transferring to a QROPS may trigger an Overseas Transfer Charge of 25%, which is only exempt if specific exemptions are met (e.g., the individual is resident in the same country as the scheme). After the October 2024 budget, the previous exemptions for EEA and Gibraltar have been abolished. Make sure to calculate this 25% before transferring.
National Insurance (NI) Pension Contributions: Expensive Since April 2026
The new State Pension requires at least 10 qualifying years to receive any amount. Those with fewer than 10 years should check their NI record before leaving, as gaps can usually be made up for the past 6 years.
Here is a recent change: Starting from April 6, 2026, overseas periods can no longer be used to make up Class 2 contributions, only Class 3. The weekly rate jumps from a few pounds to about £17.75 (about £923 per year), and new applicants must meet either "continuous residence in the UK for 10 years" or "having 10 qualifying years". The form is CF83, please read NI38 guidance before applying, and specific rates are subject to HMRC's annual announcement.
Another reminder: people abroad can still receive the State Pension, but the annual increase of applies only in EEA, Gibraltar, Switzerland, and countries with relevant social security agreements with the UK. In other places, the amount will be frozen at the level when it was first received. This is a pure rule, knowing it in advance is helpful for arrangement.

My judgment is that the most expensive mistake in leaving the UK is not missing a few hundred pounds in tax refunds, but rushing to close the UK account and moving the pension fund in one go. The former might only delay the refund, while the latter could result in a one-time loss of 25%. Slowing down can actually save money.
The table "6 Things to Do Before and After Leaving," above, is suitable for someone who is packing their luggage and will leave next month to check off each item one by one. It is also worth saving for friends who have already left but have not yet applied for the P85.
I want to ask everyone: How many years have you accumulated in your NI record now? Are you planning to continue adding up to 10 years, or are you going to stop here? Please share your strategy in the comments section, I will reply when I see it.
