Making Tax Digital for Income Tax stopped being a future date on a calendar in April 2026 — it is now live for landlords over the £50,000 threshold, and the next tier of landlords joins in under a year. If you have not yet worked out whether it applies to you, or what it actually involves day to day, here is the practical version.
Who is mandated, and when
MTD for Income Tax is being phased in by income level rather than switched on for everyone at once:
- From 6 April 2026 — mandatory if your gross qualifying income was over £50,000 in the 2024–25 tax year.
- From 6 April 2027 — mandatory if your gross qualifying income was over £30,000 in the 2025–26 tax year.
- From 6 April 2028 — mandatory if your gross qualifying income was over £20,000 in the 2026–27 tax year.
Each threshold is assessed on the tax year before the one in which you become mandated, using the income reported on that year's Self Assessment return. HMRC writes to landlords and sole traders it identifies as due to be mandated, but the responsibility to check sits with you and, ultimately, with your agent.
Why “qualifying income” catches people out
The thresholds are based on gross income, not profit. It is total rent received across your property income, combined with any self-employment income, before you deduct mortgage interest, letting agent fees, repairs, or anything else. A landlord with a handful of properties on tight margins can easily clear £50,000 in gross rent while making a modest taxable profit — and still be mandated on the strength of the turnover figure alone.
This is worth checking properly rather than assuming based on your tax bill. Jointly owned property is apportioned by ownership share for this purpose, which can pull one joint owner into MTD earlier than the other depending on how the split works and what other income each of you has.
What actually changes day to day
Once you are mandated, the annual Self Assessment return for your property and trading income is replaced by a different rhythm:
- Digital records of income and expenses, kept in MTD-compatible software rather than a spreadsheet you re-type at year end — the software needs to hold the underlying transaction data, not just a summary you paste in.
- Quarterly updates submitted straight from that software, on the standard cycle: 7 August, 7 November, 7 February and 7 May, each covering the preceding three months.
- A Final Declaration after the tax year ends, confirming the total position for the year and bringing in any other income, reliefs or adjustments that quarterly updates do not cover — this is what actually finalises your tax liability.
The quarterly updates themselves are a running total, not a fully worked tax computation — there is no requirement to calculate tax owed each quarter, and adjustments like capital allowances or apportioning private use are made at the Final Declaration stage. But the record-keeping habit that supports it has to be in place from day one of the first quarter, not assembled retrospectively.
The penalty points system
MTD carries its own penalty regime, separate from the old Self Assessment late filing penalties. Each missed submission — a quarterly update or the Final Declaration — adds a penalty point. Once you reach the relevant points threshold, a fixed financial penalty is triggered, and further missed deadlines at that point each carry their own charge. Points expire after a sustained run of on-time compliance, so the system rewards getting back on track rather than accumulating indefinitely.
HMRC has confirmed a softer first year for landlords newly brought into MTD from April 2026: penalty points are not applied for late quarterly updates during that first 12 months. This does not extend to the Final Declaration or to other obligations, so it is a grace period on the in-year mechanics, not a free pass on the year as a whole.
Exemptions, and what is not yet in scope
Below your relevant threshold, you are simply not mandated yet — there is no need to opt in early unless it suits your own record-keeping. HMRC will also accept a digital exclusion exemption where using electronic communications or keeping digital records is not reasonably practicable for you, covering reasons such as age, disability, location, or religious belief incompatible with electronic record-keeping. Property held in a trust or estate, and some other income structures, currently sit outside MTD for Income Tax entirely and follow their existing filing rules.
None of this is a reason to delay working out where you stand. The thresholds step down quickly — a landlord who is comfortably clear of £50,000 today may well be inside the £30,000 or £20,000 band within two to three years as rents rise, even without buying another property.
What to do before you are mandated
The landlords who find MTD painless are the ones who move to compatible software and clean digital records before the deadline forces the issue, not on the eve of their first quarterly submission. Practically, that means:
- Working out your gross qualifying income for the relevant prior year now, using the actual definition — not an estimate from memory.
- Moving off spreadsheets and paper records into MTD-compatible software with enough runway to bed it in before your first live quarter.
- Getting joint ownership splits and any related structuring (see our note on when an SPV makes sense) sorted before MTD adds a quarterly rhythm on top of whatever structure you are already running.
- Lining up an agent who will actually handle the quarterly cycle, not just the annual return — four filing points a year is a different service relationship than one.
Common questions
Do I need to comply with Making Tax Digital for Income Tax as a landlord?
If your gross qualifying income from property and any sole trade combined was over £50,000 in the 2024–25 tax year, MTD for Income Tax became mandatory for you from 6 April 2026. The threshold drops to £30,000 (based on 2025–26 income) from April 2027, and to £20,000 (based on 2026–27 income) from April 2028, bringing in most landlords with a meaningful portfolio over the next couple of years.
What counts as qualifying income for the MTD threshold?
Qualifying income is gross income before expenses — total rent received, not rental profit — combined across all your property income and any self-employment income. A landlord with high turnover and thin margins can be mandated even where taxable profit is modest, which catches people out.
What do the quarterly updates actually involve?
Four times a year you submit a summary of income and expenses straight from MTD-compatible software, on a standard cycle with deadlines of 7 August, 7 November, 7 February and 7 May. After the tax year ends you submit a Final Declaration confirming the total position, which replaces the Self Assessment return for that income.
What happens if I miss a quarterly deadline?
MTD uses a points-based penalty system: each missed submission adds a point, and once you reach the threshold a fixed penalty is charged, with points resetting after a period of consistent compliance. HMRC has confirmed an easier first year for landlords newly mandated from April 2026, where penalty points are not applied for late quarterly updates in that first 12 months — though other obligations, including the Final Declaration, are not covered by that easement.
Can I get an exemption from Making Tax Digital?
HMRC will accept a digital exclusion exemption where it is not reasonably practicable for you to use electronic communications or keep electronic records — for reasons including age, disability, location, or religious belief. Below the relevant income threshold you are simply not mandated yet, and jointly owned property and non-property income sources have their own specific treatment that is worth checking individually.
