Concept
Pre-arrival planning is the legal design of facts before the UK tax year begins or before residence is triggered. It is not avoidance packaging. The purpose is to identify the consequences, remove avoidable ambiguity, and not enter UK residence with unmanaged structures. The residence start date itself runs off the Statutory Residence Test, and from 6 April 2025 a UK resident is taxed on the arising basis on worldwide income and gains under RFIG41000 unless a relief applies.
This is general legal information, not individual tax advice. UK residence, treaty position, trust attribution, company residence and IHT exposure turn on facts and documents.
What pre-arrival planning fixes
Residence and the FIG window
The SRT decides the residence start date and any split-year case. A qualifying new resident — broadly UK resident after at least 10 consecutive non-resident tax years — can claim the 4-year FIG regime, and foreign employment income runs through Overseas Workday Relief. The window opens on residence, so the date is the first lever.
Portfolio, companies and trusts
Offshore fund status under IFM12144 decides whether a disposal is a gain or an offshore income gain. A foreign company's central management and control and the transfer-of-assets-abroad rules decide whether company income reaches the founder. Trust benefits and matching, and the IHT long-term-resident clock, all start counting from residence.
The planning test
The test asks what happens if the client becomes UK resident in the intended tax year. It then asks whether the outcome changes if arrival is delayed across a tax-year boundary, assets are sold before arrival, non-reporting funds are switched, a company is governed from outside the UK, trust benefits are deferred, or a treaty residence position is preserved. Each answer should rest on a document, not an intention.
Scope
The page covers individuals and families before arrival: founders with companies, investors with foreign funds, trust settlors and beneficiaries, executives with deferred compensation, and families approaching the 10-year long-term-residence mark for inheritance tax.
Consequences
Pre-arrival decisions can affect whether FIG is available, whether a gain falls inside the four-year window, whether a portfolio produces offshore income gains, whether company residence is challenged through central management and control, whether trust income is attributed to a UK-resident settlor, and when the IHT long-term-residence clock starts to matter.
Examples
A client holding non-reporting funds may switch before UK residence or decide to rely on FIG timing. A founder may move the central management and control of a foreign company away from the UK before arrival, on real facts rather than minutes. A trust beneficiary may defer distributions until the residence and FIG position is documented.
Checklist
- Model the SRT residence start date and any split-year case before the move.
- Test FIG eligibility and the four-year window, and OWR for foreign employment income.
- Review the portfolio for offshore fund status and excess reportable income by ISIN.
- Decide company governance so central management and control sits where intended.
- Map trusts, benefits and matching, and plan the timing of distributions.
- Project the IHT long-term-residence clock and the departure tail.
Common mistakes
- Leaving planning until the first UK tax return, when asset timing and governance are already fixed.
- Treating artificial arrangements or false residence evidence as planning.
- Reviewing the portfolio only after arrival, after non-reporting gains have crystallised as income.
- Changing company minutes without changing where decisions are actually taken.
- Ignoring transfer of assets abroad and CFC rules as if they were peripheral.
Advisor trigger
A tax adviser can coordinate a clean arrival where the facts are simple and documented. A UK tax solicitor should lead where there is a foreign company with UK management questions, a settlor-interested trust, large embedded gains, a treaty residence position, or a structure that needs to be re-papered before the residence start date.
Q&A
Is pre-arrival planning avoidance
No. Legal planning identifies consequences and structures facts honestly before residence. False residence evidence or artificial arrangements are a different thing, and the transfer-of-assets-abroad and CFC rules treat them as such.
Which issue should be reviewed first
The residence start date. It controls the tax year, the four-year FIG window, the split-year analysis and the IHT long-term-residence count, so every other decision keys off it.
Should portfolios be reviewed before arrival
Yes. Offshore fund status and excess reportable income can materially change the UK result, and selling non-reporting funds after arrival can convert capital growth into income.
Can a foreign company simply be run from abroad after arrival
Only if the central management and control genuinely sits abroad. Moving the minutes while the decisions stay in the UK does not move residence, and transfer of assets abroad can still attribute income to the founder.
