Making Tax Digital Penalty Points: The 4-Point Threshold

Making Tax Digital penalty points accumulate one point per late submission, and at four points HMRC charges a £200 penalty plus a further £200 for every subsequent late submission. Points attach to the taxpayer, not the agent. For US-connected UK filers, the widely reported 2026-27 quarterly easement is far narrower than the headlines suggest.

This guide deals with submission points only — the points-based late filing regime that sits under Making Tax Digital for Income Tax. Late payment penalties are a separate regime with its own mechanics and are not covered here. If you are a US citizen, green card holder or dual filer with UK self-employment or UK property income, the interaction between the two systems is where most of the avoidable cost sits, and it is almost entirely a sequencing problem rather than a tax problem.

How Making Tax Digital penalty points actually work

The regime replaces a fixed-penalty model with an accumulator. Every time you miss a submission deadline that falls inside Making Tax Digital for Income Tax, HMRC records one penalty point. Nothing is charged for the first three. The fourth point crosses the threshold and triggers the financial penalty, and from that moment every further late submission is chargeable in its own right.

• One point per missed deadline. HMRC's guidance is explicit that you can only get one penalty point per deadline, even where you run more than one business and file more than one quarterly update late for the same period. Three rental properties and a consultancy do not generate four points for one missed quarter.
• The threshold is four points. Reaching four triggers a £200 penalty.
• Every later miss costs £200. Once you are at the threshold, the meter runs on each subsequent late submission. There is no second free run of three.
• Points expire — but only below the threshold. If you stay under four, HMRC automatically removes each point 24 months after the deadline you missed. Once you hit four, automatic removal stops entirely and you must earn your way back to zero.
• Points are per tax, not per person-wide. An Income Tax points tally is separate from a VAT points tally. A founder who has been sloppy with VAT does not start Income Tax with a handicap, and vice versa.
• HMRC writes to you. You receive a letter for each point and for the £200 penalty, and each carries appeal rights.

What earns a point — and what does not

Points are awarded for missed submission obligations inside Making Tax Digital for Income Tax: the quarterly updates and the tax return that closes the year. They are not awarded for keeping poor digital records, for filing a return that later proves to be wrong, or for paying late. Accuracy failures and payment failures each sit in their own regime. This matters practically, because a client who submits four rough-but-timely quarterly updates and corrects everything at the year end carries zero points, while a client who reconstructs perfect figures three weeks after each deadline carries four.

The system rewards punctuality over precision during the year. That is a genuine behavioural shift for cross-border clients used to a single, carefully assembled 31 January filing, and it is the single most useful thing to understand before April 2026.

The four-point threshold in numbers

Position	What happens	Cost
1 late submission	1 penalty point recorded; letter issued	Nil
2 late submissions	2 points	Nil
3 late submissions	3 points	Nil
4 late submissions	Threshold reached; automatic point expiry switched off	£200
Each further late submission	Charged individually while at the threshold	£200 each
Below threshold, 24 months elapse	Each point falls away automatically	Nil
At threshold, compliance achieved	All points removed together after a clean 12 months plus catch-up of the previous 24 months	Nil going forward

Note the asymmetry. Below the threshold, time alone cures the problem. At the threshold, only active compliance does, and the compliance test reaches backwards over two years of obligations. A client who arrives at four points with historic gaps cannot simply behave for twelve months and be clean; the outstanding items have to be filed as well.

Why the 2026-27 quarterly "amnesty" is not an amnesty

HMRC has confirmed that there are no penalties for missing a quarterly update deadline for the 2026 to 2027 tax year. This has been reported almost universally as a first-year grace period, and it is the fact most likely to mislead a sophisticated filer into deprioritising the first four quarters. Three things make that reading wrong.

The updates still gate the return

A quarterly update is not an optional courtesy filing. Under Making Tax Digital for Income Tax, all outstanding quarterly updates for a tax year must be submitted before the final return for that year can be filed. The easement removes the penalty for lateness; it does not remove the obligation. A taxpayer who ignores all four 2026-27 quarters arrives in January 2028 needing to file four updates and a return in sequence, from records that may never have been kept in digital form. If that sequence is not completed by 31 January 2028, the return is late — and the return is not covered by the easement.

In other words, the amnesty relocates the risk rather than removing it. It converts four small, well-signposted deadlines into one compressed deadline sitting on top of the busiest filing week of the UK year, at exactly the point when a US-connected client is also assembling foreign tax credit data.

The return still carries a point

The easement is drawn around quarterly update deadlines. It does not extend to the tax return for 2026-27, due 31 January 2028. Miss that and a penalty point is recorded in the ordinary way. So a filer can emerge from the "penalty-free" first year already carrying one point, and that point sits on the record for 24 months — overlapping the years when quarterly points are live.

Points reach quarterly updates from 2027-28

From the 2027-28 tax year, missed quarterly update deadlines attract points like any other submission. That is four additional chargeable deadlines per year, per taxpayer, on top of the annual return — five point-bearing obligations a year where there used to be one. A filer who was comfortably compliant under the old single-deadline model can reach the four-point threshold inside a single tax year without ever being late with a return.

The arithmetic is worth stating plainly: under the old model, reaching four late filings took four years. Under Making Tax Digital it can take ten months.

The SA109 trap: why most US-connected filers get no soft landing at all

This is the point that generalist coverage of Making Tax Digital penalty points misses entirely, and it is the one that matters most to our clients.

HMRC has confirmed that taxpayers who completed the SA109 residence and remittance basis supplementary pages on their 2024/25 Self Assessment return are treated as automatically temporarily exempt from Making Tax Digital for Income Tax until April 2027. Those who did not file an SA109 for 2024/25 but reasonably expect to for 2025/26 or 2026/27 can apply for the same treatment. The stated reason is to allow the substantial changes to the taxation of non-UK domiciled individuals to be built into the regime.

Read who that actually captures. SA109 is filed by non-UK residents, by individuals claiming split-year treatment, by those claiming relief under a double taxation treaty, and by those reporting on a basis other than the arising basis. That is a very large share of the US-connected UK population: the American executive who arrived mid-year, the UK-resident US citizen claiming treaty relief, the accidental American who left the UK, the non-resident landlord who kept a Kensington flat after moving to New York.

Now combine the two timelines. The quarterly easement applies to the 2026-27 tax year. The SA109 deferral pushes entry to April 2027 — that is, the 2027-28 tax year. The tax year in which most US-connected filers are first mandated is the first tax year in which quarterly update points are live.

The practical consequence: the group most likely to assume they have a free first year is the group that has no free year at all. Their entry into Making Tax Digital is a cold start into a fully armed points regime, with four chargeable quarterly deadlines and a chargeable return in their very first mandated year.

There is a second edge. The deferral is a deferral, not an exemption in the ordinary sense, and it was framed by reference to the 2024/25 return. Clients whose residence position has changed — someone who filed SA109 for 2024/25 but has since become straightforwardly UK resident and no longer files it, or someone newly arrived who has never filed one — need their status checked rather than assumed. Getting this wrong in either direction produces either an unnecessary year of quarterly filing or an unnoticed mandation.

Are non-resident landlords in scope for UK property income?

Yes, subject to the deferral above. Residence does not remove you from Making Tax Digital; it changes what counts. A non-UK resident is taxed in the UK on UK-source income, and UK rental profits are squarely within that. Where gross UK property income exceeds the qualifying income threshold, Making Tax Digital for Income Tax applies regardless of where the landlord lives.

Three features of the qualifying income test catch cross-border landlords out:

• It is gross, not net. Qualifying income is turnover and gross rents before expenses, mortgage interest or the finance cost restriction. A London flat can be barely profitable after interest and still sail over the threshold.
• It aggregates. Sole trade income and property income are added together. A consultancy invoicing modestly plus a rental portfolio can cross a threshold that neither would cross alone.
• Foreign income is excluded for a non-resident. If you are not UK resident, income that is not UK-source does not count towards qualifying income. Your US practice income does not push your UK rental into the regime. For a UK resident, the position is different and foreign property income needs separate consideration.

The thresholds step down over time — broadly £50,000 from April 2026, £30,000 from April 2027 and £20,000 from April 2028 — so a landlord comfortably outside the regime in 2026 may be inside it by 2027 or 2028 without any change to their rents. Because SA109 filers are deferred to April 2027, most non-resident landlords will be tested for the first time against the lower £30,000 threshold, not the £50,000 one. That is a materially wider net than the headline figure implies. We cover the mechanics in more depth across our cross-border guides.

The Non-Resident Landlord Scheme, under which a letting agent or tenant may deduct basic-rate tax at source, is a separate withholding mechanism. Approval to receive rents gross does not affect Making Tax Digital scope or the points regime, and a landlord holding that approval still has quarterly and annual submission obligations once mandated.

How Making Tax Digital penalty points interact with a US filing position

Points are a UK compliance consequence, but for a dual filer their cost is rarely limited to £200. The UK return is the evidential spine of the US foreign tax credit position, and delay propagates.

Feature	UK — HMRC, Making Tax Digital for Income Tax	US — IRS, Form 1040
In-year submission obligation	Four quarterly updates per business or property source	None; estimated tax payments only, no in-year information return
Annual deadline	31 January following the tax year end (5 April)	15 April, with automatic extension to 15 June for those abroad and to 15 October on request
Late filing sanction	Points-based: 1 point per miss, £200 at four points, £200 per miss thereafter	Percentage-based failure-to-file additions calculated on tax due
Effect of nil liability	A point is still recorded for a late submission even if no tax is due	Additions are generally measured by reference to tax owed
Record-keeping form	Digital records required, maintained in compatible software	No prescribed digital format
Points/penalty follow	The taxpayer, not the agent or software provider	The taxpayer

Three interactions deserve attention:

• Foreign tax credit timing. A US filer claiming credit for UK income tax on Form 1116 needs a settled UK figure. Where the UK return slips, the US position is typically held open on extension or filed on estimates and amended. The £200 is trivial; the professional cost of an amended US return and a recalculated credit carryover is not. The IRS sets out the general framework in its foreign tax credit guidance for international taxpayers.
• Mismatched year ends. The UK tax year ends 5 April and the US year ends 31 December. Quarterly updates are built on UK-year quarters, so the data assembled for HMRC never maps cleanly onto a US calendar year. Clients who let quarterly updates drift lose the one thing the regime genuinely offers a cross-border filer: four clean, dated data cuts during the year that make the December apportionment straightforward.
• Catch-up cases. Where a client is already remediating missed US filings, an accumulating UK points record is an unhelpful signal to have running in parallel. We usually sequence the UK submission position first precisely because it is mechanical and fixable, before turning to the US side through the streamlined filing procedures.

How do you clear penalty points once you have hit four?

Two conditions must both be met, and they run in parallel rather than in sequence:

• A clean period. You must send your quarterly updates and submit your tax return on time for 12 months.
• A catch-up. You must submit any outstanding quarterly updates and any outstanding tax returns for the previous 24 months.

When both are satisfied, the whole points balance is removed at once — it does not tick down one point at a time. Until then, the balance sits at the threshold and every late submission costs £200.

The catch-up limb is the one that traps returning expatriates. Someone who left the UK, stopped filing, and later re-engages may have two years of missing obligations behind them. Clearing points requires those to be brought up to date as well as filing correctly going forward. It is worth confirming the full obligation history before committing to a twelve-month clean run, because a single forgotten historic period will defeat it.

Can you appeal a Making Tax Digital penalty point?

Yes. HMRC issues a letter for each point and for the £200 penalty, and each carries a right of appeal. Appeals turn on reasonable excuse, judged on the facts. In cross-border cases the arguments that tend to carry weight are the practical ones: serious illness, bereavement, a genuine and documented software or filing-service failure, or an unexpected event outside the taxpayer's control that prevented submission and was remedied without unreasonable delay.

Arguments that do not travel well are equally predictable. Being abroad, being busy, relying on an agent who did not file, or not having received a reminder are weak. Nor is an initial misunderstanding of scope — for example, assuming that non-residence removed you from the regime — a reliable excuse once the mandation letter has been issued. The better strategy is to file something on time and correct it, rather than to file nothing and appeal.

Multiple businesses, joint property and the one-point rule

The one-point-per-deadline rule is generous where clients have complex sources. A US-connected client running a UK consultancy, holding two rental properties personally and a share in a jointly held property has multiple update obligations for each quarter. Missing all of them on the same date produces one point, not several.

It is also a trap. Because the exposure looks small for any single quarter, it is easy to treat a missed quarter as a minor matter. The problem is the count, not the cost: four such quarters, each individually shrugged off, is the threshold. And where a complex client habitually files late because one source is always slow — a managing agent's statement that arrives at the end of the month, say — the pattern repeats predictably every quarter. Fixing the slow source is worth more than any appeal.

Jointly held property deserves a specific note. Each owner has their own qualifying income test and their own submission obligations, so a couple can be in different positions, and one spouse's points have no effect on the other's tally. Where one spouse is a US person and one is not, the sensible pattern is to keep the US person's UK submissions strictly on time so that the foreign tax credit evidence is available on the earlier US timetable.

A worked timeline: a US citizen with a London rental

Consider a US citizen who moved from London to Boston in 2024, kept a London flat producing gross rents of around £42,000, and filed SA109 residence pages with her 2024/25 UK return.

• April 2026. Not mandated. Her SA109 filing gives automatic temporary exemption to April 2027. She continues to file a conventional UK return.
• April 2027. Mandated. Her gross rents exceed the £30,000 threshold applying from this point, so she enters Making Tax Digital for Income Tax for the 2027-28 tax year — the first year in which quarterly update points are live. She receives no easement, because the easement attached to 2026-27.
• 2027-28. Five point-bearing deadlines: four quarterly updates and the 2027-28 return. Miss the August and November updates while relocating, miss February because the managing agent is slow, miss May, and she is at four points and a £200 penalty before her first Making Tax Digital return is even due.
• January 2029. The 2027-28 return falls due. If it slips, that is a fifth chargeable event at £200, and her US 2028 return — already extended — is waiting on the UK figure for her Form 1116 credit.

Nothing in that sequence involves tax avoidance, aggressive planning or complexity. It is a filing-cadence failure, and it is entirely preventable with a compatible software connection and a quarterly reminder.

What to do in the next twelve months

• Establish your mandation date, in writing. Confirm whether SA109 pages were filed for 2024/25, and whether you expect to file them for 2025/26 or 2026/27. This single fact determines whether your first mandated year is 2026-27 or 2027-28, and therefore whether you get any easement at all.
• Test qualifying income on gross figures. Aggregate gross sole trade and gross UK property income before expenses, and test against the threshold applying in your first mandated year — which for deferred filers will be the lower one.
• Fix the slowest data source now. Whichever managing agent, platform or bookkeeper is the constraint will be the constraint every quarter. Quarterly cadence exposes it four times a year.
• Do not treat 2026-27 as optional. If you are mandated from April 2026, file the quarterly updates on time even though they cannot be penalised. They gate the return, they build the habit, and they leave you with clean quarterly data for the US year-end apportionment.
• Close historic gaps before you need a clean 12 months. The point-clearing test reaches back 24 months. Anyone with old missing periods should deal with them while they are cheap.
• Sequence the UK and US calendars together. Build the UK quarterly cadence around the US extension dates rather than in isolation, so the UK figures exist before the US filing decision has to be made.

HMRC's own guidance on penalties for Making Tax Digital for Income Tax sets out the point mechanics, and its guidance on using Making Tax Digital for Income Tax covers scope, signing up and quarterly updates. Both are worth reading alongside your own mandation position rather than in place of it.

Where this leaves US-connected UK filers

Making Tax Digital penalty points are a low-value, high-frequency sanction attached to a high-frequency obligation. Individually they are trivial. Structurally they penalise exactly the filing pattern that cross-border clients default to — assemble everything once, late in the cycle, when both countries' data is finally available. The regime asks for four punctual, imperfect submissions instead, and it will charge you for preferring accuracy to punctuality.

For the SA109 population — which is to say most Americans in the UK and most non-resident landlords with US connections — the deferral to April 2027 is not a reprieve. It is a delayed entry directly into the fully operative points regime, with no first-year easement, and it arrives in the same year the lower qualifying income threshold bites. At Jungle Tax we deal with this as a preparation and sequencing exercise: establish the mandation date, confirm qualifying income on gross figures, connect compatible software, and lock the quarterly cadence to the US calendar so that neither return waits on the other. That work sits alongside our wider US and UK filing service and our private client compliance work for individuals with substantial UK and US reporting positions.

If you hold UK property or trade income and file, or expect to file, US returns, the position is worth establishing before your first mandated quarter rather than after your fourth point. To review your mandation date, your qualifying income and your quarterly filing cadence in confidence, contact our cross-border team for a private consultation. We will tell you plainly which year you enter, what you owe by when, and what needs to change before it starts.
