Moving to the UK brings significant financial opportunities, but also a set of tax obligations that can catch new residents off guard. One of the most important recent developments for internationally mobile individuals is the introduction of the four-year foreign income and gains (FIG) regime, which replaces the previous non-domicile framework and fundamentally changes how offshore income is treated during the early years of UK residency.
What the Four-Year FIG Regime Actually Means
Under the new rules, individuals who become UK tax resident after a period of at least ten consecutive years of non-residence may be eligible to claim relief on their foreign income gains regimefor up to four tax years.
During this initial period, qualifying individuals can receive foreign income and gains without those amounts being subject to UK Income Tax or Capital Gains Tax—provided the relief is claimed on their self-assessment return. This represents a significant shift from the previous remittance basis, which required careful management of how and when funds were brought into the UK.
For new arrivals, understanding this window is critical. Working with personal tax advisors who are familiar with international residency rules can help ensure the exemption is correctly claimed and fully utilised.
What Happens After the Four Years
Once the four-year exemption period ends, the individual’s worldwide income and gains become fully subject to UK taxation in the usual way. Foreign income, whether from investments, rental properties, business activities, or other sources, must be declared to HMRC and reported accurately on self-assessment returns.
This transition point requires careful planning. Offshore assets that have accumulated during the exemption window do not remain sheltered indefinitely, and the tax treatment of those assets changes materially once the FIG period expires. Early engagement with tax advisory services is strongly recommended before that threshold is reached.
Reporting Requirements Under the New Framework
Claiming the four-year exemption is not automatic. It must be actively elected on a self-assessment tax return for each relevant year. Failure to claim correctly, or failure to report foreign income and gains accurately after the exemption ends, can result in HMRC compliance issues and potential penalties.
