Frequently Asked Questions — April 2026 Update

Do I need to pay UK tax on foreign income for 2025/26? +

If you are UK resident, you must pay UK tax on your worldwide income for 2025/26. However, you may claim relief for foreign tax paid through Double Taxation Agreements. Non-residents only pay UK tax on UK income. New arrivals may be eligible for relief under the FIG regime.

How do I know if I'm UK tax resident for 2025/26? +

UK tax residency is determined by the Statutory Residence Test, considering: number of days spent in UK, UK ties (family, work, accommodation), and whether you have a home in UK. Generally, 183+ days in UK makes you automatically resident.

What is the new FIG regime for non-domiciled individuals? +

The Foreign Income and Gains (FIG) regime replaced the remittance basis from April 2025. New arrivals to the UK can claim 100% relief on foreign income and gains for their first 4 years of UK residence. After 4 years, they are taxed on worldwide income and gains. The previous remittance basis annual charges no longer apply.

Can I be tax resident in two countries simultaneously? +

Yes. Double Taxation Agreements include "tie-breaker" clauses determining which country has primary taxing rights, considering permanent home, centre of vital interests, habitual abode, and nationality.

What records do I need for foreign income? +

Essential records: foreign bank statements, payslips from overseas employers, rental agreements for foreign properties, dividend statements, foreign tax returns, currency conversion records. Keep records for at least 6 years.

What are the deadlines for foreign income reporting? +

Register for Self Assessment by 5 October 2026. File online and pay tax by 31 January 2027. For UK property sales, report CGT within 60 days of completion.
