Tax Residence Appeals: Challenging HMRC Under The Statutory Residence Test

HMRC says you were UK-resident in a year you lived abroad. The letter reaches back through years-old travel, attaches a tax bill with interest, and asks for records you may never have thought to keep. Your instinct is probably to explain where your life really was that year.

Resist it, because it aims at the wrong target. Since 6 April 2013, UK tax residence has been decided by a mechanical statutory test: the Statutory Residence Test (SRT) in Schedule 45 to the Finance Act 2013. The law is largely settled; the dispute is almost always factual—how many midnights you spent in the UK, how many hours you worked and where, which homes you had, which "ties" you kept. And under section 50(6) TMA 1970, the burden is on you to show the assessment overcharges you.

That makes residence appeals evidence appeals, won or lost on contemporaneous records—travel logs, boarding passes, tenancy agreements, phone and card statements—not on how strongly you feel you had left. Sobering if your records are thin; genuinely good news if you are organised, because the dispute is ultimately arithmetic.

How A Residence Dispute Starts

Every route into a residence dispute is a demand for facts. The usual openings:

• A "nudge letter". HMRC receives overseas-account data under international exchange agreements and invites you to check your position. A nudge letter is not an assessment and carries no appeal right—but respond carefully. If it encloses a "certificate of tax position", the professional bodies' long-standing guidance is that there is no legal obligation to sign it and it has no statutory deadline; take advice before signing anything. See nudge letters and offshore disclosure.
• An enquiry into your return. HMRC can open a section 9A TMA enquiry into the SA109 residence pages of your Self Assessment return and close it with a formal decision—see HMRC enquiries and closure notices.
• A discovery assessment. For years where nothing was returned—typically foreign income HMRC now says was taxable—it can raise a discovery assessment under section 29 TMA, subject to the time limits below.
• An information notice. Schedule 36 notices demanding travel logs, diaries and bank and card statements are how most residence enquiries gather their raw material. The power has limits—documents must be reasonably required, some material is protected, and many notices can be appealed.

Whichever letter you hold, the question underneath is the same: what do the records show, day by day? And keep perspective: most residence disputes are honest differences over how a mechanical test applies to imperfectly recorded facts, not accusations of fraud.

The Statutory Residence Test, In Order

The SRT has a strict internal order, and working it out of order produces wrong answers. You are UK-resident for a year if you meet an automatic UK test or the sufficient ties test; otherwise you are non-resident (paras 3-4). In practice you work the cascade like this: automatic overseas tests first—any one, if met, makes you conclusively non-resident and nothing else matters—then the automatic UK tests, and only then the sufficient ties test. Readers who start at the ties tables get the wrong answer.

Throughout, the SRT splits people into "leavers" (UK-resident in at least one of the three preceding tax years) and "arrivers" (resident in none). Leavers are judged more harshly at every stage.

Step 1: The Automatic Overseas Tests

Any one of these ends the analysis: non-resident.

There are death-year variants (paras 15-16), and the full-time-work test is unavailable to transport workers with cross-border "relevant jobs" (para 14(4)). The third test is where the evidence burden bites hardest: a 35-hour overseas average is proved with timesheets, contracts and work calendars, not recollection.

Step 2: The Automatic UK Tests

If no overseas test is met, any one of these makes you UK-resident.

The UK-home test is the trap for people who "kept a house in the UK": presence at the home for any part of a day, however short, counts towards the 30 days (para 8(4))—stricter than the midnight rule that governs day counting generally.

Step 3: The Sufficient Ties Test

Only if no automatic test settles the year does the ties test apply (para 17). It compares your UK day count against your number of UK "ties".

Leavers (para 18)—resident in one or more of the three preceding tax years:

Arrivers (para 19)—resident in none of the three preceding tax years:

The ties themselves (paras 31-38):

Note the asymmetry—leavers have five possible ties, arrivers four—and that the 90-day tie looks at the previous two years, so heavy past presence follows you into a carefully planned year.

Counting Days: The Real Battleground

Almost every litigated SRT case is, at bottom, about a handful of individual days. Three rules decide them.

The Midnight Rule And Transit Days

A day counts as a UK day if you are present in the UK at the end of the day—midnight (para 22(1)). Fly in at 8am and out at 10pm and you generally have not clocked a day (but see the deeming rule next).

Transit days do not count where you arrive as a passenger, leave the next day, and do nothing "to a substantial extent unrelated" to your passage through the UK (para 22(3)). In Parker v HMRC [2026] UKFTT 652 (TC), booking separate tickets rather than a single through-ticket did not stop the appellant being a "passenger", and an airport-hotel overnight and meals were connected to onward passage. Mr Parker had 100 midnights when he needed fewer than 91 and a closure notice for £64,945.65; the tribunal worked the disputed days one by one, got him to 89, and he won—an ordinary-sized dispute decided entirely on the evidence for four individual days.

The Deeming Rule

Here is the flagship trap for anyone who "kept under the limit" by day-tripping. Days without a midnight in the UK normally do not count—subject to para 23. The deeming rule applies if all three of these are met:

1. you have at least 3 UK ties for the year;
2. you have more than 30 qualifying days—days you were present in the UK at some point but not at midnight; and
3. you were UK-resident in at least one of the three preceding tax years.

Once qualifying days pass 30, every further qualifying day is treated as a day spent in the UK (para 23(4)). A leaver with three ties who commutes in and out without ever staying overnight starts accruing UK days from trip 31. The day-band tables are only safe once you have checked this rule. (One small mercy: deemed days do not feed the 90-day tie—para 23(5).)

Exceptional Circumstances And The 60-Day Cap

A day can be disregarded if you "would not be present in the UK at the end of that day but for exceptional circumstances beyond [your] control that prevent [you] from leaving the UK", and you intend to leave as soon as they permit (para 22(4)). The statutory examples are "national or local emergencies such as war, civil unrest or natural disasters" and "a sudden or life-threatening illness or injury" (para 22(5)). And there is a hard cap: no more than 60 days can be disregarded in a tax year, counted from the start of the year (para 22(6)). Once used, further days count even if the crisis continues.

The leading case is A Taxpayer v HMRC [2025] EWCA Civ 106. The taxpayer had moved to Ireland, needed to stay within 45 days, and spent 50 midnights; around £3.1 million turned on six days spent caring for her twin sister—alcoholic and suicidal—and the sister's young children.

The Court of Appeal held that "exceptional" is an ordinary English word, not a term of art; that "prevent" is not limited to legal or physical impossibility, so a sufficiently compelling moral obligation can prevent someone leaving; but that the threshold stays high—the circumstances must be "truly compelling" and "objectively compelling", judged against societal expectations, and Parliament "did not intend the exceptional circumstances test to be met too readily". An earlier Upper Tribunal ruling that only legal or physical constraints—not moral obligations—could "prevent" someone leaving was overruled; the Court of Appeal's framework is the current law. (One humane detail: the tribunal anonymised the case to protect the taxpayer's family.)

Crucially, whether circumstances are exceptional is a question of fact. Findings of fact stand on further appeal unless no reasonable tribunal could have made them—the Edwards v Bairstow discipline, which protected the taxpayer's win here and would equally have protected a loss. Parker then applied the framework to everyday facts: a flight cancelled after boarding when Storm Jorge closed Dublin Airport was exceptional, prevention was judged by "practical reality rather than abstract possibility", and taking the airline's rebooked flight next morning satisfied the intention to leave as soon as circumstances permitted.

Do not over-read this relief. The threshold is high and objective, the cap is absolute, and A Taxpayer spent the best part of a decade in litigation over five days beyond a 45-day limit.

Split Years: Which Case, What Date

Residence is normally all-or-nothing for a tax year (para 2(3)). Part 3 of Schedule 45 softens this: in a "split year" the year divides into a UK part and an overseas part, and the charge follows the split. Two structural points. It is automatic—there is no election (before 2013 it was only a concession, ESC A11). And it does not change your residence status: you remain UK-resident for the whole year; only the charge is split (para 40(3)).

A split year must fall within one of eight Cases:

Where more than one Case applies, priority rules decide (paras 54-55): Case 1 beats 2 beats 3 for leavers; for arrivers, Case 6 generally wins unless Case 5 gives an earlier date, and otherwise the earliest split date wins. In practice the dispute is rarely whether the year splits but which Case applies and therefore what the split date is—different Cases can produce dates months apart, and a bonus, dividend or gain landing between two candidate dates falls in or out of UK tax accordingly.

The Five-Year Rule: Temporary Non-Residence

If you left the UK, realised income or gains while away, and came back, Part 4 of Schedule 45 is waiting: temporary non-residence. It applies, broadly, where you had sole UK residence before departure, at least 4 of the 7 tax years before the year of departure were years of sole UK residence, and your period of non-residence is 5 years or less (para 110(1)).

The effect is charged in the year you return. The regime catches, among other things, distributions from close companies (broadly, your own company's dividends), pension flexible-drawdown payments and certain lump sums, chargeable event gains on life policies, and remitted foreign income. For capital gains, section 1M TCGA 1992 treats gains on assets you held at departure and sold while away as accruing in the period of return—and a double tax treaty does not block the charge (s.1M(4)).

This is the law behind the folklore that you must "stay out five full years". The test is a period of non-residence of 5 years or less, measured through technical definitions of residence periods and split years—which is why returning even slightly early can bring years of gains and income home with you. (Separately: non-residents disposing of UK property have a 60-day reporting obligation of their own, and pension withdrawals caught by this rule sit alongside the charges in our pensions guide.)

Old Years, Old Law

A residence enquiry rarely stays in one year. Discovery time limits run to 4 years as standard, 6 for carelessness, 12 years for offshore matters (section 36A TMA), and 20 years for deliberate behaviour (section 36 TMA)—so years before the SRT existed can still be assessed today. What "deliberate" means is set by Tooth v HMRC, and the discovery machinery has conditions HMRC must satisfy—see discovery assessments and Langham v Veltema.

For years before 6 April 2013, residence was a common-law concept, and a famously vague one—Levene v IRC [1928] UKHL 1 put it as one's "settled or usual abode". In R (Davies and Gaines-Cooper) v HMRC [2011] UKSC 47, the Supreme Court held that HMRC's old guidance booklet IR20 never promised that day counts alone secured non-residence: a "multifactorial inquiry" into whether the taxpayer had made a "distinct break" from the UK was required. The uncertainty that litigation exposed is why Parliament enacted the SRT.

Two cases show what fighting an old year looks like. In Hargreaves v HMRC [2022] UKUT 34 (TCC), the Matalan founder said he left for Monaco in March 2000 and sold roughly £231 million of shares that May; an £84 million discovery assessment for 2000-01, raised in 2007, was still in litigation in 2022. He lost—critically, because he did not give evidence, HMRC's case that he had been careless went unrebutted. That is this article's moral in one case: where the taxpayer will not put evidence in, the burden decides the appeal.

In Lyons v HMRC [2023] UKFTT 294 (TC), a CGT assessment of over £1 million for 2012-13—the last pre-SRT year—was upheld a decade later: putting his UK home on the market was not a "distinct break". A 2012 year and a 2022 year are fought on different law; know which fight you are in.

The 2025 Regime Change (And Why Residence Now Matters More)

From 6 April 2025, the remittance basis and domicile as a tax connector were abolished (Part 2 of the Finance Act 2025, s.40). In their place is the foreign income and gains (FIG) regime: someone non-UK-resident for each of the 10 tax years before arrival (section 845B ITTOIA 2005) can claim relief on foreign income and gains for up to 4 tax years. Two cautions. Each of those 10 prior years is itself an SRT question, so an HMRC challenge to one old year can knock out FIG eligibility entirely. And a claim costs you your personal allowance (and, for gains claims, the CGT annual exempt amount) for the year (s.845E)—it can cost more than it saves, so consider advice before claiming, not after.

In passing: the Temporary Repatriation Facility lets pre-6 April 2025 foreign income and gains be designated in a 2025-26 or 2026-27 return at 12%, rising to 15% for 2027-28, then closes. For inheritance tax, domicile has been replaced by a long-term-residence test—broadly, UK residence in at least 10 of the previous 20 tax years (section 6A IHTA 1984)—see our IHT guide. Pre-2025 remittance-basis and domicile disputes continue under the old law through enquiries into those years.

The upshot: residence is now the sole personal connector for income tax and CGT—which is exactly why a residence enquiry is worth more to HMRC than ever, and why your day-count records have become some of the most valuable paperwork you own.

Dual Residence And Treaties

The SRT can make you UK-resident in a year when another country's rules also claim you. Double tax treaties resolve this with a tie-breaker, typically Article 4: residence goes to the state where you have a permanent home; if you have one in both, to the state with which your personal and economic relations are closer (the "centre of vital interests"); failing that, habitual abode; failing that, nationality.

Recent cases show it cutting both ways. In Oppenheimer v HMRC [2022] UKFTT 112 (TC), the taxpayer was resident in both the UK and South Africa with permanent homes in both; the tribunal found his centre of vital interests—the things of greatest importance to him, assessed year by year—lay in South Africa, and assessments exceeding £10 million were cancelled. HMRC did not appeal, but it is a first-instance decision: persuasive illustration, not binding rule.

In McCabe v HMRC [2024] UKUT 280 (TCC)—the current authority at Upper Tribunal level—it went the other way: a taxpayer who moved to Brussels remained UK-resident at common law, a Scarborough family house owned solely by his wife was still a permanent home "available" to him, and his centre of vital interests was the UK. Note how low the "available" bar sat.

Treaty residence, where it applies, overrides UK residence only for the treaty's purposes—you remain UK-resident under domestic law, with the filing obligations that follow (and treaty non-residence can itself engage the five-year rule above by breaking "sole UK residence"). The tie-breaker is intensely fact-hungry and among the least DIY-able topics here: if your case turns on Article 4, take professional advice.

Appealing A Residence Decision

First, identify what you are appealing—the letter's own wording tells you. An invitation to "check your tax position" (with or without a certificate to sign) is a nudge letter, not appealable; a "notice of enquiry" under section 9A opens an enquiry; a closure notice, a notice of assessment (including a discovery assessment) or a penalty notice is an appealable decision. From there the route is the standard direct-tax one:

• Appeal in writing within 30 days of the decision (section 31 TMA 1970). Missed the window? A late appeal is possible but the test is strict.
• Consider a free statutory review—a fresh HMRC officer, normally within 45 days—see HMRC internal review. You keep your tribunal right afterwards.
• Notify the First-tier Tribunal (£0 fee)—see our filing guide; around 45% of appellants represent themselves.
• Apply to postpone the disputed tax under section 55 TMA while the appeal runs—see postponing payment. Interest still accrues on whatever is ultimately due, currently at 7.75%—see interest on unpaid tax. The mirror is true too: if you pay and later win, the tax comes back with repayment interest (at a lower rate). And if some tax is genuinely due and you cannot pay it at once, HMRC can agree instalments through a Time to Pay arrangement.

The one option that never improves your position is doing nothing. Once the appeal window passes, an assessment or closure notice becomes final: the tax is legally due and enforceable, interest keeps running, and your arguments about the SRT never get heard. An ignored nudge letter, meanwhile, tends to escalate into exactly the enquiry or discovery assessment it warned about.

Section 50(6) puts the amount of the assessment on you to displace; HMRC bears the burden on the discovery conditions and on penalties. Watch the penalty overlay: if HMRC says you were resident and never notified your liability—the deadline is 5 October after the end of the tax year (section 7 TMA)—failure-to-notify penalties can apply, with offshore territory uplifts reaching 200% of the tax in the most serious categories. Penalties are appealed separately, with their own defences: see self-assessment penalties, reasonable excuse and reducing HMRC penalties. If you conclude HMRC has a point, coming forward early is itself a lever—the quality and timing of disclosure drives the penalty percentage down, and unprompted disclosure is treated markedly better than prompted.

Understand what the First-tier Tribunal hearing is: effectively your one shot on the facts. An onward appeal to the Upper Tribunal (permission application within 56 days of full written reasons) lies only on a point of law—the Edwards v Bairstow gateway explained in our Upper Tribunal guide. In a residence case nearly everything—day counts, transit, what was exceptional, where your vital interests lay—is fact; win or lose it at the FTT, it will almost certainly stand.

Know the practical shape of the fight too. A First-tier appeal typically takes typically 6-12 months to reach a decision—the decade-long sagas in the case law above are outliers, prolonged by multiple onward appeals. But check your track: larger residence appeals are often allocated to the Complex track, where the loser can be ordered to pay the winner's costs unless you opt out of the costs regime within 28 days of allocation—see tribunal tracks and costs. And an appeal is not a one-way street to a hearing: many disputes end by agreement or through ADR—see settling your tax tribunal case.

Two boundary markers. Complaints that HMRC took years over the enquiry, or that the online residence checker misled you, are conduct complaints for HMRC's complaints process and the Adjudicator, not tribunal grounds—the limit explained in our analysis of Hok v HMRC. And National Insurance residence is a completely separate system with its own gateway rules—do not read your SRT result across to NIC in either direction; see National Insurance when working abroad.

What To Do Now

1. If you already hold a decision, diary the deadline first. You have 30 days from the decision to appeal. Get the appeal in and apply to postpone the disputed tax—everything else on this list can follow.
2. Start the evidence file today. Keep a real-time day-count diary, and retain boarding passes, e-tickets, hotel invoices, mobile phone location and billing records, and card statements. For a year already in dispute, reconstruct it: passport stamps, airline and booking-account travel histories, card-transaction locations and phone billing records can rebuild a day count you never kept. Contemporaneous records win residence appeals—Hargreaves is what losing for want of evidence looks like.
3. Run the SRT in order, before the marginal trip. Automatic overseas tests, then automatic UK tests, then ties—and check where the year stands before booking travel that eats into a band.
4. Check the deeming rule before trusting the day-band tables. Three ties, prior residence and more than 30 no-midnight visit days means your day trips have started counting.
5. Leave a buffer. A Taxpayer litigated for the best part of a decade over five days beyond a 45-day limit. Exceptional circumstances has a high objective threshold and a hard ceiling of 60 days—it cannot rescue a year planned to the wire.
6. Treat the HMRC checker as an indication only. The online "Check your UK residence status" tool is only as good as the facts typed in, and its output binds no one—including HMRC.
7. Check the vintage of any guidance you rely on. HMRC moved its SRT guidance in the 2025 restructure: the RDRM11xxx page numbers many articles still cite are dead, and the RDR3 note is now a short summary that defers to the manual. The live guidance is the Residence and FIG Regime Manual, RFIG20000 onwards.
8. If a dispute is live, prepare it like the evidence case it is. See writing grounds of appeal, preparing for your hearing and the tax dispute timeline. For advice on your specific position, a qualified adviser is worth engaging early—residence errors compound across years.
