Landlord MTD ITSA Phasing: what £30,000, £20,000 and the 2028 rollout really mean
Most people searching this topic are trying to answer a very practical question: when does Making Tax Digital for Income Tax Self Assessment actually start for landlords, and does the threshold apply to rental profit or to gross income? In 2026, that question matters more than ever, because the rollout is now live at the top end, the £30,000 phase is close behind, and HMRC has confirmed a further drop to £20,000 from April 2028.
What the phasing means in plain English
The current HMRC timetable is straightforward, but many summaries still leave out the detail that changes the real-life decision. If your qualifying income was over £50,000 in your 2024 to 2025 Self Assessment return, you need to use MTD for Income Tax from 6 April 2026. If it was over £30,000 in 2025 to 2026, your start date is 6 April 2027. If it is over £20,000 in 2026 to 2027, your start date is 6 April 2028.
That phasing matters because it is not based on a vague “future landlord digital tax” idea. It is already tied to specific tax years and specific thresholds. In practice, that means a landlord can be completely outside MTD for one year and then pulled in the next year purely because their previous year’s qualifying income crossed the relevant line. HMRC’s own guidance says it looks at the Self Assessment return you submitted in the previous year and expects you to check the figure yourself, even if no letter arrives.
The threshold is not rental profit
This is the point that causes the most mistakes. HMRC defines qualifying income as the total income from self-employment and property in a tax year, and it assesses that figure on a gross basis, before expenses. In other words, the test is not your rental profit after mortgage interest, repairs, agent fees, and other costs. It is the income figure before those deductions.
For landlords, that distinction is decisive. A portfolio owner can have modest taxable profit after expenses yet still be dragged into MTD because the gross rents are high. The opposite can also happen: someone with several expenses may think they are “small scale” because the profit is low, when their qualifying income is actually above the threshold. HMRC’s guidance even uses a simple combined example: £25,000 rental income plus £27,000 self-employment income gives a qualifying income of £52,000.
Who is likely to be caught earlier than they expect
The phrase “landlord MTD” is often treated as if it only concerns people who own one or two buy-to-lets. That is too narrow. HMRC’s rules apply where you are already in Self Assessment, and you have income from self-employment or property, or both. So a landlord who also freelances, consults, or runs a side business can be pulled in by the combined figure. By contrast, income from PAYE employment, dividends, State Pension, private pensions, and a partner’s share of partnership profit do not count towards qualifying income.
That means several common profiles need close attention. A company director with rental income may not be brought in by salary or dividends alone, but the property income can still trigger MTD. A contractor with a limited company and a personally owned rental property is in a different position again: the company’s profits are not part of the MTD ITSA test, but the rental business can still bring the individual in. HMRC’s guidance is clear that only self-employment and property income count towards the threshold.
Jointly owned property is another area where misunderstandings are common. HMRC says your share of the property income counts towards your qualifying income. So if two owners split rental income equally, each person is tested on their own share, not on the full rent for the property. Where you only know your share after expenses have already been deducted, HMRC says it will assess that figure for the qualifying-income test.
There is also a practical point for landlords with more unusual income patterns. If you receive property income in a period shorter or longer than 12 months, HMRC expects the figure to be annualised for the threshold test; if you are a property income recipient, you need to do that yourself. That matters for new landlords, properties let part way through the year, and cases where a business begins or stops mid-year.
Why the 2028 rollout matters now, not later
The £20,000 phase is not a distant policy note any more. HMRC published the 2026 measure reducing the mandation threshold from £30,000 to £20,000, and the official guidance now states that landlords and sole traders with qualifying income over £20,000 in the 2026 to 2027 tax year will need to use MTD from 6 April 2028.
For landlords, the practical consequence is that many people who would previously have thought of themselves as “below the radar” now need to watch the 2026 to 2027 tax year very carefully. A portfolio that sits safely below £30,000 in qualifying income may still be brought in two years later if it grows, or if a landlord also has a modest self-employment income stream. The policy direction is clear: digital record-keeping and quarterly updates are being extended downwards in stages, not as a one-off leap.
What MTD actually changes for landlords
MTD for Income Tax is not just a new filing deadline. HMRC says landlords will need compatible software to create, store and correct digital records, send quarterly updates, and then submit the annual tax return through the software. The government also says spreadsheets can still be used, but only where they are linked to software capable of sending the updates and return , often called bridging software.
That matters because many landlords assume MTD is simply “Self Assessment, but online”. It is more demanding than that. Quarterly updates are summaries of income and expenses, not full tax returns, and they must be sent every three months for each property business or sole trader business you have. The annual return still exists, and the tax bill is still due by 31 January after the tax year ends.
For landlords with several income streams, the admin burden rises quickly. HMRC’s guidance expects the software to show the year’s figures, let you check them, and allow you to add other income sources such as savings or dividends before the return is filed. In other words, the annual return remains a consolidation step, but the record-keeping now has to be maintained much earlier in the year.
The compliance risk is not only late filing
One of the more useful 2026 changes is HMRC’s transitional approach to penalties. For taxpayers required to use MTD for Income Tax from 6 April 2026, HMRC says it will not apply penalty points for late quarterly updates in the first tax year, 2026 to 2027. The sign-up guidance repeats that point, but it also makes clear that penalties still apply for late tax returns or late payment of tax.
That is important because it removes one fear while leaving another intact. The first-year grace for late quarterly updates should not be mistaken for a free pass on the whole regime. A landlord who misses the annual return deadline, or pays the tax bill late, remains exposed. HMRC’s separate penalties guidance confirms that MTD introduces points-based late submission penalties and late payment penalties, with the new regime applying from the tax year you join MTD.
Who is exempt, and who may stop needing MTD later
Not every landlord who crosses the threshold will necessarily be in MTD immediately, because HMRC does allow exemptions in specific circumstances. The official exemption guidance says that if you are exempt until April 2027, you do not need to sign up and use MTD for Income Tax until the 2027 to 2028 tax year at the earliest. HMRC also says that some groups are deferred or exempt under separate policy changes, though those rules are specific and should not be assumed without checking.
There is also an exit route. HMRC says that once you are in MTD, if your qualifying income drops below the relevant threshold for three tax years in a row, you can choose to opt out. If all of your self-employment or property income sources have ceased since your last Self Assessment return, you will not need to use MTD for Income Tax, although you may still have to file a return for some other reason.
That is useful for landlords who sell a property, leave the rental market, or simplify their affairs. The key point is that cessation matters. A landlord who merely has a quieter year is not automatically outside the regime; HMRC’s guidance looks at continuing sources of income, ceased sources, and whether the qualifying-income threshold is still met.
The mistakes HMRC’s guidance helps you avoid
The first mistake is waiting for a letter. HMRC says it may write to you if it reviews your return and finds your income above the threshold, but it also says you must check your own qualifying income and sign up even if no letter arrives. That is a subtle but important compliance point, because the responsibility is not transferred to HMRC’s notice system.
The second mistake is mixing up qualifying income with taxable profit. For landlords, those are different figures, and the distinction is often the difference between staying out of MTD for another year and being forced in. The third is forgetting that your own share of jointly owned rental income counts separately. The fourth is assuming partnership income, dividends or employment income count towards the threshold when HMRC says they do not.
A fifth mistake is ignoring amendments to earlier Self Assessment returns. HMRC says it will consider amendments to see whether they affect qualifying income or the start date for MTD, but amendments that increase qualifying income above the threshold after the relevant tax year has started will not be counted for MTD purposes for that year. That is a technical point, but a useful one when checking whether an amendment changes the mandate date.
A practical way to prepare now
The most sensible approach is to use the current tax year as a planning trigger, not a retrospective surprise. Work out your qualifying income from your most recent Self Assessment data, not just your profit-and-loss summary. Then check whether you are likely to move from the £50,000 phase into the £30,000 or £20,000 phases in the next two tax years. HMRC’s own step-by-step guidance makes clear that the start date depends on the previous year’s qualifying income.
For landlords with regular bookkeeping, the software decision should be made early. HMRC says compatible software is needed to create digital records, send quarterly updates and submit the return. If you already use spreadsheets, you may be able to keep them, but you still need software that links to them. That is often the point at which people realise MTD is a process change, not just a filing change.
A simple readiness checklist is usually enough for most landlords:
Check whether your qualifying income is over £50,000, then watch the £30,000 and £20,000 phases closely.
Separate property income from dividends, PAYE, pension income and partnership profit, because those items do not count towards the threshold.
Confirm whether any property is jointly owned, ceased, overseas, or part-year only, because those facts can change the threshold calculation.
Make sure your bookkeeping software can produce quarterly updates and an annual return in the format HMRC expects.
Build in the filing dates: quarterly updates by 7 August, 7 November, 7 February and 7 May for the standard April-start cycle.
Summary of key insights
MTD ITSA for landlords is now a staged rollout, not an abstract future reform: £50,000 from 6 April 2026, £30,000 from 6 April 2027, and £20,000 from 6 April 2028.
The threshold is based on gross qualifying income, not net rental profit, and only self-employment and property income count. Joint ownership, ceased sources, overseas property, and mixed-income cases can all affect the result.
Quarterly digital updates, compatible software, and a final annual return become part of the compliance cycle, although HMRC has said there will be no penalty points for late quarterly updates in the first MTD tax year for those starting in April 2026.
FAQs
Q1: Can someone still stay outside MTD if their rental profit is low but their gross rent exceeds the threshold?
A1: Well, this catches far more landlords than people expect. HMRC looks at gross qualifying income, not the profit left after mortgage interest, repairs, insurance, or agent fees. I recently reviewed a case where a landlord’s taxable profit was barely £11,000 after heavy refurbishment costs, yet the gross rents were above the threshold, so MTD still applied.
That distinction matters because many landlords judge themselves by “what’s left over”, while HMRC looks at turnover-style figures instead. It’s one of the most common misunderstandings appearing in landlord forums at the moment.
Q2: Can someone use spreadsheets instead of accounting software for landlord MTD reporting?
A2: Yes, but there’s a catch people often miss. A spreadsheet on its own is not enough because it cannot submit directly to HMRC. In practice, the landlord usually needs bridging software linking the spreadsheet to HMRC’s system.
For landlords with one or two properties, this can actually work quite well if records are already organised. The real issue is consistency. I’ve seen landlords using three separate tabs, handwritten receipts, and bank exports that don’t reconcile properly. Quarterly reporting becomes messy very quickly when the underlying records are chaotic.
If someone prefers spreadsheets, the key is keeping categories clean from day one rather than trying to rebuild everything at quarter-end.
Q3: Can a landlord with jointly owned property fall into MTD while the other owner stays outside it?
A3: Absolutely , and this surprises couples quite regularly. MTD applies individually, not per property. One spouse may exceed the threshold because they also have freelance income or another rental property, while the other spouse remains below the limit.
Consider a couple in Manchester jointly owning a flat producing £24,000 annual rent. One spouse also earns £18,000 from sole-trader consulting work. Their combined qualifying income crosses the threshold, but the other spouse’s share does not.
That means one person may have quarterly reporting obligations while the other continues under normal Self Assessment rules.
Q4: Does overseas rental income count towards the MTD income threshold?
A4: In most cases, yes. Overseas property income is generally included when working out whether someone falls within the MTD rules. That’s particularly relevant for UK residents with holiday apartments abroad or inherited overseas property.
In practice, the tricky part is record keeping rather than the threshold itself. Foreign agent statements, exchange rates, and local expenses often create timing differences that become harder to track quarterly. I’ve noticed landlords with overseas property usually underestimate how much admin MTD creates compared with standard annual reporting.
Where foreign tax has already been paid, double tax relief rules still matter separately.
Q5: Can someone leave MTD later if their rental income drops below the threshold?
A5: Yes, potentially , but not immediately. HMRC does not normally remove someone from MTD after one weaker year. The rules generally look for qualifying income remaining below the threshold for multiple tax years before an opt-out becomes available.
That means landlords selling one property should not automatically assume the quarterly obligations disappear straight away. There can be a lag before HMRC treats the taxpayer as outside the regime again.
It’s worth checking carefully after major portfolio changes rather than assuming the system updates itself automatically.
Q6: Does a limited company property business fall under landlord MTD ITSA rules?
A6: No , and this is one of the biggest misconceptions online. MTD for Income Tax applies to individuals with property or self-employment income. A limited company landlord remains under Corporation Tax rules instead.
However, directors often get confused because they personally complete Self Assessment returns as well. If a person owns buy-to-lets personally alongside a property company, only the personally owned rental income counts towards MTD ITSA.
I’ve seen directors accidentally combine company turnover with personal rents when estimating their threshold exposure, which creates unnecessary panic.
Q7: Can a landlord with one rental property still be affected by MTD?
A7: Very easily, especially in parts of London and the South East where rents are higher. A single property can produce enough gross rent to trigger the rules, even where the mortgage and expenses heavily reduce the taxable profit.
There’s also a growing group of accidental landlords , people renting out former homes while working elsewhere , who assume MTD only affects “professional landlords”. HMRC does not really distinguish between a large portfolio owner and someone with one qualifying property if the income threshold is met.
Q8: Do quarterly updates mean landlords must pay tax four times a year?
A8: No, and this misunderstanding refuses to disappear. Quarterly updates are reporting obligations, not quarterly tax bills. Payment dates broadly remain aligned with the existing Self Assessment system.
A lot of landlords panic because they assume every quarterly submission triggers an immediate HMRC demand. In reality, the updates are more like progress snapshots of income and expenses.
That said, better visibility can indirectly change behaviour. Some landlords who previously ignored their tax position until January may end up budgeting more consistently throughout the year.
Q9: Can someone with both PAYE employment and rental income be pulled into MTD?
A9: Yes, although PAYE salary itself does not count towards the threshold calculation. What matters is whether the qualifying property and self-employment income exceeds the limit.
For example, a teacher earning £42,000 under PAYE with rental income of £32,000 gross could still fall within MTD because the rental income alone breaches the relevant threshold.
This creates confusion because many employed landlords assume PAYE “covers everything already”. It doesn’t remove the separate digital reporting obligations for property income.
Q10: Does the Rent a Room scheme affect whether someone enters MTD?
A10: It can, depending on how the income is treated. Rent a Room relief does not automatically remove the reporting obligation if the receipts form part of qualifying property income.
A fairly typical example is someone in Bristol renting two furnished rooms while also freelancing part-time. Individually, each income source may look modest, but together they can unexpectedly push the taxpayer into MTD territory.
Where people rely on informal arrangements or cash transfers from lodgers, record keeping often becomes the real weak point.
