What the SA109 Exemption Means for Americans in Britain
The SA109 exemption removes you from Making Tax Digital for Income Tax until April 2027, and most Americans with UK income qualify without lifting a finger. Furthermore, the relief is automatic for anyone who filed SA109 residence pages with their 2024/25 return. Consequently, thousands of US citizens who received a warning letter from HMRC never needed to act on it at all.
Timing makes this urgent. Making Tax Digital for Income Tax started on 6 April 2026 for taxpayers with qualifying income above £50,000. Additionally, the first quarterly deadline has already passed. Many American landlords and consultants in Britain rushed into software they did not need.
This guide sets out precisely who qualifies for the SA109 exemption and how to claim it. Moreover, it covers a permanent exemption that most commentary ignores entirely. Finally, it explains what changes in April 2027 and what your US return needs from all of this.
How the SA109 Exemption Works in Practice
The SA109 exemption is a temporary deferral rather than a permanent escape. Specifically, HMRC confirmed that every taxpayer who completed SA109 pages on the 2024/25 return falls outside Making Tax Digital for the 2026/27 tax year. Therefore, mandation begins from 2027/28 at the earliest.
Importantly, the deferral is granted by reference to a form, not to your residence status. Consequently, UK residents qualify just as readily as non-residents, provided they filed those pages. The HMRC exemptions guidance sets out the position in full.
Why HMRC Created the Deferral
The reason is technical rather than generous. Britain overhauled the taxation of non-UK domiciled individuals from April 2025, replacing the remittance basis with the foreign income and gains regime. Subsequently, SA109 absorbed a raft of new claims and elections.
Consequently, HMRC needed time to build those changes into Making Tax Digital software. The Chartered Institute of Taxation and the Association of Taxation Technicians both confirmed the scope in April 2026. Thus, the SA109 exemption exists because the software cannot yet handle your circumstances.
Who the Deferral Does Not Cover
Not every American with UK income files SA109. Notably, a US citizen who is straightforwardly UK resident, claims no treaty relief and holds no foreign income claims may never touch those pages. Therefore, that person faces Making Tax Digital in the ordinary way.
Nevertheless, other exemptions may still apply. Specifically, the qualifying income threshold and the National Insurance number rule both operate independently. Accordingly, treat the SA109 exemption as one route among several rather than the only one.
Are You an SA109 Filer? The Full Test
Here is the question every article dodges. Determining whether you qualify for the SA109 exemption means determining whether you file SA109 at all. Fortunately, HMRC publishes the complete list of triggers.
Non-Residence and Dual Residence
You file SA109 if you were not UK resident for the tax year. Additionally, you file it if you were UK resident but also tax resident in another country under that country's rules. Consequently, an American who spends substantial time in both London and New York frequently lands in this category.
Notably, the pages also cover non-resident claims to UK personal allowances under a double taxation agreement. However, US citizens should tread carefully here. HMRC's international manual on personal allowances does not list the United States among the treaties granting them, so a US-only national who is non-resident generally gets no UK personal allowance at all.
Overseas Workday Relief and Split-Year Treatment
Overseas Workday Relief triggers SA109. Therefore, an American banker who moved to London recently and claims relief on non-UK workdays qualifies for the SA109 exemption automatically. Additionally, anyone expecting split-year treatment on arrival or departure files the same pages.
Furthermore, these situations are common among the clients we act for. Executives relocating to Britain almost always file SA109 in their arrival year. Consequently, the deferral catches a large share of recently arrived Americans without them realising it.
The FIG Regime and the Temporary Repatriation Facility
The foreign income and gains regime requires an SA109 claim. Likewise, an election under the temporary repatriation facility appears on the same pages. Accordingly, wealthy new arrivals using either relief qualify for the SA109 exemption as a matter of course.
Moreover, former remittance basis users often still file. Specifically, someone expecting a remittance above the £10 aggregate, or claiming business investment relief, completes SA109 too. Therefore, historic non-dom status frequently continues to secure the deferral years later.
Non-Resident Entertainers, Sportspeople and Others
The list extends further than most readers expect. Notably, non-UK resident entertainers and sportspeople file SA109. Additionally, former remittance basis users whose investment relief has ceased to qualify must complete the pages.
Consequently, the practical test is simple. Look at your 2024/25 return. If the residence pages are there, your SA109 exemption already applies and no action is required.
Automatic Versus Applied-For: Claiming Your SA109 Exemption
Two routes exist, and confusing them causes real problems. Fortunately, the distinction is straightforward once you know which year HMRC examines.
The Automatic Route
HMRC grants the SA109 exemption automatically where the 2024/25 return included those pages. Therefore, no application, letter or phone call is needed. Furthermore, your agent need do nothing either.
Practically, that means you can ignore any Making Tax Digital signup letter you received. Nevertheless, keep the letter on file. Additionally, retain a copy of the filed SA109 as evidence that the deferral applies to you.
The Application Route
The position differs where you did not file SA109 for 2024/25. Specifically, taxpayers who reasonably expect to include those pages in their 2025/26 or 2026/27 return must apply to HMRC for the exemption. Consequently, a recent arrival to Britain frequently falls into this second group.
Importantly, this catches people who moved to the United Kingdom during 2025 or 2026. Their first SA109 has not yet been filed, so no automatic deferral exists. Therefore, they must use the apply for an exemption service rather than assume the relief is granted.
What HMRC Will Not Accept
Separately, a permanent digital exclusion exemption exists for those genuinely unable to use digital tools. Specifically, HMRC accepts age, a health condition or disability, religious belief, and an inability to obtain internet access at your location. However, the bar is high.
Conversely, HMRC rejects applications based on unfamiliarity with software, a preference for paper filing, a small volume of records, or the cost and time involved. Therefore, do not treat digital exclusion as a fallback if the SA109 exemption does not apply to you.
The Permanent Exemption Most Advisers Miss
This is the point almost every competing guide omits, and it matters enormously to overseas owners of UK property. Some exemptions never expire.
No National Insurance Number
HMRC states that you are automatically exempt, and cannot even sign up, if you do not hold a National Insurance number before the start of the tax year. Critically, that exemption is permanent rather than temporary. Consequently, it survives April 2027 entirely.
Furthermore, this catches a large population of American owners of British property. An investor who bought a London flat while living in the United States generally never obtained a National Insurance number. Therefore, that person sits outside Making Tax Digital indefinitely, quite apart from any SA109 exemption.
Other Permanent Exemptions
Additional permanent carve-outs apply. Notably, qualifying income of £20,000 or less exempts you outright. Likewise, non-resident companies filing SA700, personal representatives of deceased persons, and Lloyd's members using SA103L fall outside the regime.
Moreover, HMRC has confirmed permanent treatment beyond April 2027 for ministers of religion, Lloyd's members with property income, and recipients of Blind Person's Allowance. Accordingly, several routes outlast the SA109 exemption itself.
Why This Matters for Overseas Property Owners
Combining the two reliefs produces a durable position. Specifically, a non-resident American landlord with no National Insurance number holds a permanent exemption underneath a temporary one. Consequently, the April 2027 deadline poses no threat to them.
Nevertheless, verify rather than assume. Many Americans obtained a National Insurance number during an earlier period of UK employment and have forgotten it. Therefore, check your records before relying on this route.
Qualifying Income: The Threshold Test That Decides Everything
Even without the SA109 exemption, the threshold may keep you out. However, the definition trips up more people than any other part of the regime.
Gross Income, Not Profit
Qualifying income means gross receipts before any expenses, allowances or reliefs. Therefore, a landlord collecting £62,000 in rent with £30,000 of mortgage interest and costs still counts as £62,000. Consequently, profitability is irrelevant to the test.
Furthermore, employment income does not count. Specifically, only self-employment turnover and property receipts enter the calculation. The HMRC qualifying income guidance explains the mechanics precisely.
What Counts for a Non-Resident
Non-residents enjoy a narrower test. Notably, only UK source self-employment income and UK property income fall within scope. Therefore, foreign source income sits entirely outside Making Tax Digital.
Consequently, an American living in Boston who owns two Manchester flats counts only the British rents. Additionally, that person's US consulting practice and American rental portfolio are ignored completely. Accordingly, many overseas owners never reach the threshold despite substantial worldwide income.
The £50,000, £30,000 and £20,000 Phasing
Three thresholds apply in sequence. Qualifying income above £50,000 for 2024/25 brought mandation from 6 April 2026. Subsequently, £30,000 for 2025/26 brings mandation from 6 April 2027, and £20,000 for 2026/27 brings it from 6 April 2028.
Importantly, HMRC reviews your Self Assessment return each year and writes to you when you cross a threshold. Nevertheless, HMRC states plainly that the responsibility to check remains yours even if no letter arrives. Therefore, silence from HMRC proves nothing.
What Happens When the SA109 Exemption Ends in April 2027
Treating the deferral as permanent is the single most expensive mistake available here. Ultimately, it buys you twelve months and nothing more.
The 2027-28 Mandation
From the 2027/28 tax year, SA109 filers with qualifying income above £30,000 must comply. Consequently, the threshold falls at precisely the moment the SA109 exemption expires. Therefore, a landlord with £35,000 of gross rents moves from fully exempt to fully mandated in a single step.
Furthermore, the transition demands preparation rather than a scramble. You must keep digital records, submit quarterly updates, and finalise the year through compatible software. The HMRC step-by-step guidance for landlords and sole traders sets out the sequence.
Quarterly Updates and Penalty Points
Making Tax Digital replaces one annual return with five submissions. Specifically, quarterly updates fall due on 7 August, 7 November, 7 February and 7 May, followed by a year-end finalisation. Additionally, a points-based penalty regime applies to late submissions.
Consequently, the administrative burden multiplies for people already juggling two tax systems. Moreover, American filers must reconcile those quarterly figures with a US return running on a calendar year. Accordingly, the mismatch between the tax years becomes materially harder to manage.
Preparing Before the Deadline
Use the deferral period productively. Practically, that means moving property and business records onto compatible software during 2026/27 rather than April 2027. Furthermore, run a parallel quarter voluntarily to test the process.
Additionally, confirm which exemption you actually rely on. Someone protected only by the SA109 exemption faces a hard deadline. Conversely, someone without a National Insurance number does not. Therefore, the distinction determines how much work the next year requires.
The US Side: What Making Tax Digital Changes on Your 1040
British digital reporting does not alter American law. However, it changes the data you hold and the timing of what you know.
Foreign Tax Credits and Timing
Your UK tax liability still feeds your American foreign tax credit claim on Form 1116. Nevertheless, quarterly updates do not create quarterly liabilities. Therefore, the credit still depends on tax paid or accrued, not on the update cycle.
Furthermore, the year-end mismatch persists. Britain runs to 5 April and America to 31 December. Consequently, apportioning UK tax across two US years remains the real work, and Making Tax Digital does nothing to simplify it.
Records That Serve Both Systems
There is a genuine upside. Digital record-keeping produces cleaner data for both returns. Additionally, well-structured property records make Schedule E preparation considerably faster.
Therefore, we encourage clients to design their bookkeeping around both jurisdictions from the outset. Specifically, capture gross rents, allowable UK expenses and US-deductible items separately. Consequently, one system serves two filings without duplicated effort.
Property Owners and Overlapping Obligations
Overseas landlords carry several duties at once. Notably, the non-resident landlord scheme governs whether rent reaches you gross or after deduction. Additionally, non-resident capital gains reporting applies within sixty days of a UK property disposal.
Moreover, none of these obligations pause because the SA109 exemption applies. Therefore, deferral from Making Tax Digital changes the reporting mechanism only. Your underlying UK and US filing duties continue exactly as before.
Joint Ownership, Partnerships and Disputed HMRC Letters
Three practical situations recur constantly in our work, and published guidance addresses none of them clearly. Fortunately, each has a workable answer.
Jointly Owned Property and Mixed-Nationality Couples
Making Tax Digital applies to individuals rather than to properties. Therefore, each owner tests their own qualifying income against the threshold separately. Consequently, a couple splitting £70,000 of gross rents equally each counts £35,000, not £70,000.
Importantly, the SA109 exemption follows the individual too. Specifically, an American spouse claiming the foreign income and gains regime may hold the deferral while their British partner does not. Accordingly, one household can face two entirely different Making Tax Digital positions on the same flat.
Partnerships Are Not Yet Mandated
Partnership income sits outside the current rollout. Notably, HMRC has confirmed that partnerships will join Making Tax Digital in future but has not published a timeline. Therefore, an American partner in a UK professional partnership faces no quarterly obligation on that income at present.
Nevertheless, personal property and sole trade income still count. Consequently, a partner who also lets a London flat tests that rent against the threshold in the ordinary way. Moreover, the ICAEW technical guidance on Making Tax Digital sets out the treatment of mixed income sources in detail.
When HMRC's Letter Is Simply Wrong
HMRC issues signup letters from qualifying income data alone. Consequently, those letters frequently reach people whose SA109 exemption already removes them from the regime. Understandably, the correspondence causes alarm.
However, an incorrect letter carries no obligation. HMRC's own guidance directs taxpayers who disagree to contact the department rather than sign up regardless. Furthermore, the underlying framework sits in the Income Tax (Digital Requirements) Regulations 2021, which is worth citing if you need to press the point. Therefore, check your position, keep the evidence, and correct the record rather than complying unnecessarily.
Keep Filing Your Self Assessment Return
One misunderstanding deserves flagging. An exemption from Making Tax Digital is not an exemption from Self Assessment. Specifically, HMRC states that exempt taxpayers must continue reporting income and gains through a Self Assessment tax return in the usual way.
Consequently, the SA109 exemption changes the mechanism rather than the obligation. Additionally, your 31 January filing and payment deadlines continue unchanged. Therefore, treat the deferral as relief from quarterly reporting alone.
Case Study: An American Consultant With London Property
Consider James, a client profile reflecting work we handle regularly. He is a US citizen who moved to London in 2023, works as an independent strategy consultant, and owns two rental flats in Clapham.
His 2024/25 figures made him a Making Tax Digital candidate. Specifically, his consultancy turnover reached £96,000 and his gross rents came to £47,400. Consequently, qualifying income of £143,400 sat far above the £50,000 threshold, and HMRC wrote to him in early 2026 requiring signup.
James had already bought accounting software and budgeted £2,400 a year for quarterly compliance support. However, he had also claimed Overseas Workday Relief on his 2024/25 return, which meant SA109 pages were filed. Therefore, the SA109 exemption applied automatically and the HMRC letter was simply wrong for his circumstances.
The saving was immediate. He avoided four quarterly updates for 2026/27 and the associated professional fees. Additionally, he sidestepped the penalty risk attached to the 7 August, 7 November and 7 February deadlines.
Critically, the deferral does not last. From 2027/28 the threshold drops to £30,000, and James remains comfortably above it. Consequently, we are migrating his records onto compatible software during 2026/27 while no deadline pressure exists. Meanwhile, we structured his bookkeeping so the same records feed his Form 1116 and Schedule E, saving roughly a further £900 of annual preparation time.
How TaxYork Can Help
TaxYork prepares US and UK tax returns for high-net-worth individuals, investors and business owners across Britain. Furthermore, we check every client's Making Tax Digital position each year. Specifically, we confirm whether the SA109 exemption applies, whether a permanent exemption applies instead, and whether an application to HMRC is required.
Moreover, we handle the underlying returns on both sides. Our US tax returns for expats service covers the American filing, while our tax treaty optimisation service addresses residence articles, credits and sourcing. Consequently, your SA109 claims and your US positions remain consistent.
Additionally, we support clients who have fallen behind. Our IRS Streamlined Filing service brings delinquent American returns up to date, and our FBAR and FATCA reporting service covers foreign account disclosures. Therefore, one team manages the whole cross-border position.
Conclusion
The SA109 exemption buys most Americans in Britain a full year away from Making Tax Digital. Furthermore, it arrives automatically for anyone who filed residence pages with the 2024/25 return. Therefore, many people who signed up for software during 2026 did so unnecessarily.
Above all, do not mistake deferral for escape. The relief ends in April 2027, and the threshold simultaneously falls to £30,000. Ultimately, the sensible course is to confirm which exemption protects you, then use the intervening year to prepare properly rather than react late.
