Becoming UK Resident Again
When you return to the UK, you become UK tax resident again based on the Statutory Residence Test. Once resident, you’re taxed on your worldwide income.[2]
Split-Year Treatment
In the year you return, you may qualify for split-year treatment, so you’re only taxed on worldwide income from the date of your return. Foreign income earned before your return may not be taxable in the UK.[2]
Temporary Non-Residence Rules
If you were non-resident for fewer than 5 complete tax years, the temporary non-residence rules may apply. This means certain income and gains you received while abroad could be taxed when you return, including:[4]
- Capital gains on assets you sold while non-resident
- Pension lump sums withdrawn while abroad
- Dividend income from close companies
5-year rule: These anti-avoidance provisions are designed to stop people leaving the UK briefly to realise gains or income tax-free. If you were non-resident for 5+ complete tax years, they generally don’t apply.
Reporting Foreign Income
Once UK resident, you must report all foreign income on your Self Assessment return. You may be able to claim credit for foreign tax paid under a double taxation agreement.[1] Once registered, you can submit your return online using HMRC-recognised software.
National Insurance
When you start working in the UK again, you’ll pay NI through your employer (PAYE) or through Self Assessment if self-employed. Check your NI record for any gaps from your time abroad.[5]
Practical Steps on Return
- Update your address with HMRC
- Register for Self Assessment if you have untaxed income to report
- Check your tax code with any new employer
- Review your NI record for gaps
- Take professional advice if you have significant overseas assets or income
Frequently Asked Questions
Do I pay UK tax on worldwide income when I return to the UK?
Yes. Once you become UK tax resident again under the Statutory Residence Test, you are taxed on your worldwide income. You may qualify for split-year treatment so only income from the date of return is taxable.
What are the temporary non-residence rules?
If you were non-resident for fewer than 5 complete tax years, certain income and gains received while abroad — such as capital gains and pension lump sums — may be taxed when you return to the UK.
Can I claim double taxation relief on foreign income?
Yes. Once UK resident, you must report all foreign income on your Self Assessment return, but you can claim credit for foreign tax already paid under a double taxation agreement.
What should I do about National Insurance when I return to the UK?
Check your NI record for gaps from your time abroad. You may be able to pay voluntary contributions to fill any gaps and protect your State Pension entitlement.
