Arriving in the UK to settle is not a single event for tax purposes; it is a sequence of statutory triggers across SRT, FIG, NRCGT, NRL cessation, LTR for IHT, and (for returning UK nationals) s.10A. The two operative entry points are the FIG 4-year window under ITTOIA 2005 ss.845A-845J (gateway test: non-UK-resident for each of the 10 tax years before the arrival year, per s.845B(1)) and the IHT Long-Term Resident clock under IHTA 1984 ss.6A-6C (worldwide-asset UK IHT exposure once UK-resident in 10 of the preceding 20 tax years). The popular shorthand 'new arrivals get 4 years tax-free on foreign income' is wrong on three counts: FIG requires a per-year claim under s.845A; it forfeits the UK personal allowance, dividend allowance and CGT annual exempt amount each claim year; and the gateway is 10 tax years of prior non-residence, not 4. The most-misexplained corner of the inbound regime is the FA 2025 Schedule 11 CGT rebasing election: condition 3 of paragraph 1(1) excludes UK situs assets absolutely, so an inbound non-dom holding a UK BTL acquired before arrival cannot rebase it. This page walks the inbound decision tree, the SRT split-year Cases 4 to 8, the FIG eligibility test with two worked contrasts (qualifies vs fails the 10-year gateway), the rebasing trap, NRCGT on any pre-arrival UK property disposal, NRL turn-off mechanics, the LTR clock with an HNW worked example, the TRF for returning non-doms, and 14 of the most common inbound landlord questions.
