Making Tax Digital for Income Tax is no longer a future event. From 6 April 2026 it is the law for landlords whose gross property income tops £50,000, replacing the once-a-year self-assessment return with four quarterly updates and a year-end finalisation. The figure that decides your obligation has already been earned: HMRC tests the £50,000 threshold against your 2024/25 return, so for many landlords the question is not whether to prepare but how quickly.
This is the gateway guide to the whole regime. It sets out exactly who is in scope and when, the quarterly deadlines that actually matter (the 7th of the month, not the dates a lot of older articles still quote), the penalty rules including the first-year grace HMRC has confirmed, and a realistic plan to get ready. Where a single mechanic needs deeper treatment, we link to the page that owns it.

When does Making Tax Digital start for landlords?
The start date is 6 April 2026, but only for the first tranche of landlords. The threshold then steps down over two further years, pulling progressively smaller landlords into the regime:
| Mandated from | Gross qualifying income over | Threshold tested against your |
|---|---|---|
| 6 April 2026 | £50,000 | 2024/25 self-assessment return |
| 6 April 2027 | £30,000 | 2025/26 self-assessment return |
| 6 April 2028 | £20,000 | 2026/27 self-assessment return |
The operative law is the Income Tax (Digital Obligations) Regulations 2026 (SI 2026/336), which came into force on 1 April 2026 and replaced the earlier 2021 regulations. HMRC writes to taxpayers who appear to be in scope, but the obligation is yours regardless of whether a letter arrives, so do not wait for the post.

Who is in scope, and how the threshold is measured
The threshold is the single most misunderstood part of the regime, because it is measured on gross income, not profit. Qualifying income is the total of your gross property rents and any gross sole-trade turnover, added together, before a single pound of expenses comes off.
That distinction decides real cases. Consider a higher-rate landlord with two buy-to-let flats producing £56,000 of gross rent, against which sit £41,000 of mortgage interest, letting fees, repairs and insurance. The net profit is only around £15,000, yet because gross rent is £56,000 the landlord is mandated from 6 April 2026. This gross test is exactly why so many landlords who think of themselves as small are caught: heavy borrowing depresses profit but not turnover. For the detail on what does and does not count towards the figure, see our guide to the gross versus net qualifying income test and the rental income threshold and exemptions.
If you also run a sole-trade business, the two streams are aggregated: £30,000 of trade turnover and £25,000 of rent is £55,000 combined, which crosses the £50,000 line even though neither stream does on its own.
Joint owners test their own share
Each co-owner tests the threshold against their share of the gross rent, never the property's total. A married couple owning a portfolio 50/50 that produces £100,000 of gross rent each test £50,000, putting both on the boundary for April 2026. A Form 17 election that splits the income 75/25 brings the 75% owner into scope earlier than their partner, and each spouse files their own quarterly updates. The trap is reporting the whole property under one person; that is not how the test or the filing works. Our note on the jointly owned property threshold split works through the variations.
Who is outside the regime
Several categories sit outside MTD for Income Tax:
- Limited company landlords. Companies file a CT600 under separate corporation tax digital rules. MTD for Income Tax does not touch them, so do not assume incorporation either triggers or solves an MTD problem.
- General partnerships and LLPs. These were proposed for a later phase and are deferred to a date still to be confirmed. A partner with separate personal rental or trade income may still be in MTD through that other income.
- Trustees. Trust property income continues through the SA900 trust return.
- Genuinely digitally excluded individuals. A narrow exemption exists where digital filing is not reasonably practicable, applied for through HMRC.
Non-UK resident landlords with UK rental income are in scope where the threshold is met; the non-resident landlord scheme runs alongside MTD rather than instead of it. If you are comparing the personal route with a company, our buy-to-let limited company guide sets out the wider trade-offs, with MTD as one factor among many.
The quarterly deadlines: the 7th of the month, not the 5th
A great deal of older content quotes the wrong dates. Under MTD for Income Tax the standard update periods follow the tax-year quarters and the submission deadline is the 7th of the month after each period ends:
| Quarter | Update period | Submission deadline |
|---|---|---|
| Q1 | 6 April to 5 July | 7 August |
| Q2 | 6 July to 5 October | 7 November |
| Q3 | 6 October to 5 January | 7 February |
| Q4 | 6 January to 5 April | 7 May |
| End-of-period statement and final declaration | Full tax year | 31 January following year-end |
So the first ever quarterly update for the April 2026 cohort covers 6 April to 5 July 2026 and is due by 7 August 2026, confirmed on HMRC's send quarterly updates guidance. The remaining 2026/27 deadlines fall on 7 November 2026, 7 February 2027 and 7 May 2027.
Each quarterly update is a summary of income and expenses for the period, not a detailed line-by-line return. You report what was actually received and paid in the quarter; there is no need to apportion annual costs like insurance across the four updates. If you prefer to align to calendar quarters (ending 30 June, 30 September, 31 December and 31 March), HMRC allows a calendar-quarter election from 6 April 2026. The full calendar, including the election mechanics, lives on our MTD quarterly deadlines for 2026/27 page, and the practical filing walkthrough is on the step-by-step quarterly reporting guide.
A worked first-year timeline
Take a landlord mandated from 6 April 2026. Their year runs like this:
- By 7 August 2026: submit Q1 (6 April to 5 July).
- By 7 November 2026: submit Q2 (6 July to 5 October).
- By 7 February 2027: submit Q3 (6 October to 5 January).
- By 7 May 2027: submit Q4 (6 January to 5 April).
- By 31 January 2028: submit the end-of-period statement and final declaration for 2026/27, and pay any balancing tax.
Quarterly updates are informational. Your tax-payment dates do not change to four a year: payments on account and the balancing payment continue on the usual 31 January and 31 July rhythm.
Digital records and software, without the product pitch
From your start date you must keep digital records of property income and expenses and submit them through functional compatible software. Paper records and standalone spreadsheets do not meet the rule on their own. HMRC maintains a recognised software list, and a spreadsheet is acceptable provided it connects to HMRC through approved bridging software.
The phrase that catches people out is the digital link. Data must move from your source record to your quarterly submission without manual re-keying. Bank-feed imports, cell formulae, linked tables and API extracts are digital links; copy-paste and typing figures across by hand are not. In practice that means importing bank transactions rather than retyping them, storing receipts digitally with a link to the relevant entry, and recording rent from a bank feed or property-management integration.
We deliberately do not name products or quote prices here, because the right tool depends on your portfolio and how your records are already kept. For a structured comparison of the options, including free-tier routes and the spreadsheet-plus-bridging approach, see our guide to MTD software for landlords. The detail on what HMRC accepts as a digital record (and what it does not) is on the digital record keeping requirements page. Records must be kept for the usual retention period; there is no special headline records penalty for landlords in the MTD regime, despite what some older articles claim.

Penalties and the first-year grace
The penalty rules split into two separate systems, and conflating them is a common error.
Late quarterly updates are points-based. Each missed update earns one penalty point. A £200 penalty applies once you reach four points within a rolling 24-month window, and further £200 penalties follow while you remain at the threshold. There is no immediate fine for a single late update. Points reset only when you meet two conditions together: a clean compliance period and all submissions due in the preceding 24 months made. This regime sits at Schedule 24 to the Finance Act 2021, which is a different provision from the long-standing inaccuracy penalties.
Crucially, HMRC has confirmed a first-year grace. Its guidance states plainly that it will not apply penalty points for late quarterly updates during the 2026 to 2027 tax year. In effect, the April 2026 cohort is not penalised for late submission of its first four quarterly updates. That is a genuine, confirmed concession, not a vague soft-landing promise, but it does not extend to the tax itself.
Late payment of tax is charged separately and the rates are now sharper. Following Spring Statement 2025, MTD for Income Tax late payment is charged at 3% of the unpaid tax once it is 15 days overdue, a further 3% at 30 days, and then 10% per year from day 31. These accelerated rates are tougher than the older self-assessment schedule and apply even during the quarterly-update grace period. The full mechanics, with a worked example, are on our MTD penalties guide and the 15/30/31 day late-payment worked example.
How MTD interacts with the rest of your property tax
MTD changes when and how you report, not what you owe. The substance of property taxation is unchanged, and a few points are worth holding clearly in view.
Section 24 still applies in full. Individual landlords cannot deduct mortgage interest from rental profit and instead receive a basic-rate (20%) tax reducer. Quarterly reporting does not soften that; if anything, seeing the numbers four times a year makes the impact of the restriction more visible. Our landlord tax return and key dates guide sets the MTD timeline against the wider self-assessment calendar.
Furnished holiday lets are now ordinary property income. The FHL regime was abolished from 6 April 2025, so what used to be a separately favoured category now sits inside the same rental figures and the same quarterly cycle. Former FHL rents count towards your threshold and are reported alongside the rest of the portfolio.
The future rate split is enacted but does not change MTD itself. From 2027/28 separate property-income tax rates (22%, 42% and 47%) apply in England, Wales and Northern Ireland, with the Section 24 reducer rising to 22% in step so no new basic-rate wedge opens. Scotland is carved out for 2027/28 only. None of this changes the MTD filing mechanics, but it does reinforce the case for reviewing structure and reliefs while you reorganise your record keeping.
Used well, the quarterly rhythm can help rather than hinder. Reviewing figures every three months makes it easier to time deductible spending, watch your position against the higher-rate threshold, and plan capital expenditure, rather than discovering the picture once a year in January.
How to prepare for your start date
Preparation is mostly about getting your records onto a digital footing well before the first deadline, not about last-minute software shopping. A sensible sequence:
- Confirm whether and when you are in scope. Total your gross rents (and any trade turnover) for the relevant test year and match it to the threshold table above.
- Choose compatible software early. Pick from HMRC's recognised list, or set up a spreadsheet with approved bridging software, and give yourself time to import history and connect bank feeds.
- Move record keeping to a quarterly habit. The shift from an annual shoebox to organised monthly bookkeeping is the real change. Build the routine before it is compulsory.
- Decide who files. If you would rather an accountant handled quarterly submissions, agree that now and complete the Agent Services Account authorisation, which each joint owner must do separately.
- Plan cash flow. Payment dates are unchanged, but tighter late-payment penalties make it more important to set tax aside as you go.

Common misconceptions
A few myths cause unnecessary worry:
- "Quarterly updates mean paying tax four times a year." No. Updates are informational; payment dates are unchanged.
- "Small landlords are exempt." The threshold is gross, not profit, and steps down to £20,000, so most landlords with even a single financed property are caught within three years.
- "A late update is an instant £200 fine." No. It is points-based, £200 only applies at the four-point threshold, and the first year carries a confirmed grace on late updates.
- "MTD is a soft launch I can ignore for a year." The grace covers late quarterly updates, not late payment, and the obligation is live from day one.
Where to go next
This page is the map; the deep guides below are the territory. If your portfolio, ownership or income picture is at all complex, the gross-income test, the joint-owner rules and the penalty interaction are exactly where mistakes get expensive. A short conversation with a property tax specialist can confirm your start date, set up compliant records and, if you want, take the quarterly filing off your hands entirely.
