The 183-day figure everyone (and general AI) anchors on is only the ceiling — a leaver with 3 UK ties is resident at just 46 days, and at 121 days a single tie is enough. The input that decides which table applies — were you UK-resident in any of the 3 prior tax years — is the one users never volunteer, so this tool leads with it. Includes the deeming rule for non-midnight days, which AI answers routinely miss.","inputSchema":{"type":"object","properties":{"priorResidence":{"description":"Were you UK tax resident in any of the 3 prior tax years? The decisive input, and the one everyone omits when they ask \"am I resident?\".

A leaver can be resident at 46 days; an arriver never before 46.","type":"string","enum":["leaver","arriver"],"default":"leaver"},"days":{"description":"Days present in the UK at midnight this tax year Count days you were in the UK at the end of the day (midnight).

The statutory test in brief: averaged ≥35 hours/week of overseas work over the year (HMRC applies a precise 5-step hours calculation), no significant break (31+ days without an overseas workday), and fewer than 31 UK workdays of more than 3 hours. Answer yes only if you would clear the full test.","type":"string","enum":["no","yes"],"default":"no"},"automaticUkHome":{"description":"Do you meet the UK home test? Yes if you had a UK home you were present in on ≥30 days this year, and there was a window of 91 consecutive days (at least 30 of them falling in this tax year) during which you had no overseas home — or were present in every overseas home you had on fewer than 30 days in the year.","type":"string","enum":["no","yes"],"default":"no"},"automaticUkWork":{"description":"Did you work full-time in the UK?

The third test’s 91-day limit counts actual midnight days only — deemed days never enter it.","Automatic UK tests: 183+ days; or the home test (a UK home you were present in ≥30 days, with a 91-consecutive-day window — at least 30 days of it in-year — during which you had no overseas home or were present fewer than 30 days in every overseas home); or full-time UK work (365-day period, >75% of 3-hour-plus workdays in the UK, no significant break).","Sufficient-ties tables (inclusive day bands, against days + any deemed days).

Arriver, from 4 possible ties (the country tie does not exist for arrivers): 46–90 days → all 4; 91–120 → ≥3; 121–182 → ≥2.","Day counting and the deeming rule: a day counts if you were in the UK at midnight; exceptional-circumstances days (capped at 60) are excluded, as are transit days. Leavers with 3+ ties: every day present-but-not-at-midnight past the first 30 is ADDED to the day count — for the ties-table lookup only, not for the third automatic overseas test and not for the 90-day tie. When counting the 3 trigger ties the 90-day tie is assessed without deemed days (anti-circularity); with this form’s user-asserted ties the rule reduces to: deemed = max(0, qualifying days − 30) when ties ≥ 3.","Split-year treatment (8 statutory cases) can divide a residence year into UK and overseas parts; this tool decides full-year residence only.","Sources: FA 2013 Sch 45 (the statute — tests in Part 1, ties defined in Part 2, day counting and deeming in paras 22–23); HMRC’s RDR3 guidance note; and the HMRC Residence and FIG Regime Manual, RFIG20000 series — HMRC relocated the SRT guidance there from the old RDRM11000 pages, so an answer citing RDRM pages is dated. The SRT itself is unchanged for 2025-26 and 2026-27; the new foreign-income-and-gains (FIG) regime consumes SRT outcomes rather than altering them.
