Moving abroad does not automatically end your UK tax responsibilities. Depending on your residence status and income, you may still need to file UK tax returns after leaving.
The awkward part is often the overlap: a UK property, an unfinished tax year or a business you will continue running overseas. Use this checklist to identify what needs attention before the move.
Establish Your Tax Residence
Your flight date is not necessarily the date your UK tax residence ends. The Statutory Residence Test considers your days in the UK, work patterns, accommodation and other connections. Spending fewer than 183 days here does not automatically make you non-resident.
Before leaving, record your travel dates, UK workdays and changes to your home and employment arrangements. These details help establish whether you qualify for split-year treatment, which divides an eligible departure year into UK and overseas parts; it is not automatic simply because you move mid-year.
Tell HMRC Correctly
At a minimum, update HMRC with your overseas residential and correspondence addresses. The correct departure reporting route depends on your circumstances:
- Already completing Self Assessment? Report your departure through your tax return, normally including the SA109 residence pages.
- Not required to complete a return? Form P85 may be appropriate, particularly where you could reclaim overpaid employment tax.
- Received a notice to file? Submit the return unless HMRC withdraws that notice even if you believe nothing is payable.
HMRC’s own online filing service does not support SA109. Use suitable commercial software, an accountant or a paper return, allowing for the earlier paper deadline.
Check Continuing UK Income
Non-residence does not make every UK income source tax-free. UK property income, work performed here and some pensions can remain taxable, although treaty provisions may change the treatment.
Create an income list covering:
- Employment, bonuses and share awards
- Rental profits and business income
- Pensions, savings and investments
If the same income is taxable in both countries, examine the relevant double taxation agreement. Relief may require a claim; do not assume the two tax authorities will resolve it automatically.
Decide What Happens to Property
Renting out your UK home? Review the Non-resident Landlord Scheme. Its “usual place of abode” test differs from the Statutory Residence Test, so the two should not be treated as interchangeable. Without HMRC approval to receive rent gross, your agent or, in certain circumstances, your tenant—may need to deduct tax. Gross-payment approval does not itself make the rent tax-free.
Selling UK property after leaving? Non-residents generally must report UK property or land disposals within 60 days of completion, even where no tax is due. Discuss reliefs and the calculation before completion. See HMRC’s disposal guidance.
Review Business and Investment Arrangements
Moving personally does not close your limited company or cancel its accounts, Corporation Tax and Companies House obligations. Managing it from another country can also create overseas company-residence, payroll or business-presence questions. Obtain advice in both jurisdictions before changing how the business operates.
If you stop self-employment, notify HMRC and deal with your final return, outstanding invoices, VAT and payroll where applicable.
Also review:
- ISAs: You can normally retain existing ISAs, but generally cannot subscribe while non-resident, subject to exceptions; overseas tax treatment may differ.
- Pensions and National Insurance: Check contribution eligibility, your State Pension forecast and any gaps before making voluntary payments.
- Planned disposals: Seek advice before selling investments or taking substantial company distributions, especially if returning to the UK is possible.
Put Deadlines in Your Diary
For Self Assessment, these are the usual deadlines after the relevant tax year ends; special arrangements can apply where HMRC issues a late notice to file.
| Action | Usual deadline |
|---|---|
| Notify HMRC if newly required to file | 5 October |
| Submit a paper return | 31 October |
| Submit an online return | 31 January |
| Pay the balancing tax bill | 31 January |
For example, an online return for 2026/27 is normally due by 31 January 2028. Budget for any payments on account as well as the final bill.
Keep accessible copies of payslips, P45s, travel records, property statements, investment costs and previous returns. Make sure overseas phone access will not prevent you signing into your tax accounts.
How Reflex’s accountants can assist with your Tax matters
A useful pre-departure review should leave you with answers: when your residence position changes, what remains taxable and which returns are still required.
Speak to Reflex Accounting’s non-resident accountants about bringing your residence assessment, departure reporting, rental accounts and continuing UK obligations into one agreed plan.
For anyone retaining UK property or business interests, coordinated support is more useful than treating the move as a one-off form-filling exercise. Ask for clear responsibilities, deadlines and fees before engagement.
Frequently Asked Questions
Will leaving trigger a tax refund?
Possibly, particularly if you leave employment part-way through the tax year. Your total income and tax already paid determine the result; P85 or Self Assessment may be the appropriate route.
Can I stop filing immediately?
Not necessarily. Continuing UK income may require returns, and an existing notice to file remains effective unless HMRC withdraws it.
Can Reflex Accounting help me understand my UK tax position before I move abroad?
Yes. Our non-resident accountants can assess your position using the Statutory Residence Test, review your UK income and explain your reporting obligations. This helps you understand what needs attention before departure and which responsibilities may continue after you move.
Can you manage my UK tax returns while I live overseas?
Yes. Reflex Accounting prepares and submits UK tax returns for non-residents, taking account of relevant income, allowable expenses and any available allowances or treaty reliefs. We also handle HMRC correspondence, helping you manage your UK tax affairs without returning in person.
