MTD Phase 2: Mandatory Digital Filing Requirements for Small Business Owners Explained
Index:
Making Tax Digital for Income Tax (MTD IT) enters its second phase on 6 April 2027, extending the mandatory digital reporting regime to sole traders and landlords with qualifying income above £30,000, tested against their 2025/26 tax return. This sits alongside the first phase, already live since 6 April 2026 for those over £50,000, and a third phase due from April 2028 at £20,000. If your turnover for the year that ended on 5 April 2026 fell between £30,000 and £50,000, this phase is aimed squarely at you, and the reference year has already closed, so the numbers that matter are already fixed even though the return may not yet be filed.
Most of the business owners I speak to about this have half-heard the headline figures from the news coverage of the first phase in April, and assume either that it does not apply to them yet, or that it works exactly the same way it did for the first group. Neither assumption is entirely safe, and there is one difference in particular, around penalties, that catches Phase 2 entrants out.
The three-phase rollout in full
Phase | Qualifying income threshold | Mandatory from | Tested against |
Phase 1 | Over £50,000 | 6 April 2026 | 2024/25 tax return |
Phase 2 | Over £30,000 | 6 April 2027 | 2025/26 tax return |
Phase 3 | Over £20,000 | 6 April 2028 | 2026/27 tax return |
HMRC's guidance on finding out if and when you need to use Making Tax Digital for Income Tax sets out this staged timetable and confirms that each threshold is assessed against the tax return for the year immediately before the phase begins. Once a taxpayer is brought in at any phase, a quieter year afterwards does not remove them. The thresholds only ever add people to the system as they step down, they never take anyone back out because turnover happened to dip.
The government has said the position for those below £20,000 will continue to be kept under review, with no committed date for bringing that group in, and there is no announced timetable at all for partnerships, which remain outside Making Tax Digital for Income Tax entirely for now, regardless of turnover.
Working out whether Phase 2 catches you
Qualifying income is gross turnover, before expenses, combining all self-employment income and your own share of property income. This is worth restating precisely because it is the single most common source of confusion I see: a landlord with a £42,000 rental turnover and heavy finance costs, leaving a genuinely modest profit, is still squarely within Phase 2 based on that gross figure, not the profit that ends up being taxed.
Two practical points follow from this. If you jointly own a rental property, only your own share of the gross income counts toward your individual threshold, so a couple splitting income 50:50 on a property grossing £80,000 each have £40,000 of qualifying income from that source individually, which is enough to bring each of them into Phase 2 on its own. And where someone runs a sole trade alongside a smaller let property, the two are added together for the test, so a trader with £24,000 of self-employment turnover and an £8,000 furnished holiday let, or a standard residential letting, has combined qualifying income of £32,000 and is caught by Phase 2, even though neither source alone would have been close to the threshold.
Because the reference year for Phase 2 is 2025/26, which ended on 5 April 2026, anyone currently completing or reviewing that year's figures, whether they have filed the return yet or not, already knows the number that decides this. There is no need to wait for a letter from HMRC to work this out for yourself.
What compliance actually involves
The mechanics are the same regardless of which phase brings you in. You keep digital records of business and property income and expenses using HMRC-recognised compatible software, submit a quarterly update for each business or property source through that software, and complete a single final declaration after the tax year ends, replacing the Self Assessment return you would otherwise have filed. None of this changes your tax rate, your personal allowance, or your payment dates. It changes only the mechanism by which your figures reach HMRC and how often.
Quarterly updates are running totals of income and expenses, not mini tax returns, and they do not calculate or trigger a tax payment on their own. The final declaration is where everything comes together, business profits, property income, and any other income such as employment earnings or dividends, to calculate your total liability for the year, still due by the same 31 January deadline that applies under the current system.
MTD for Income Tax Phase 2: Interactive Qualifying Income Calculator & Readiness Dashboard
This interactive dashboard helps UK sole traders, landlords, and company directors quickly determine whether they must comply with Making Tax Digital for Income Tax from 6 April 2027. By entering your gross self-employment turnover and property income share from the 2025/26 tax year into the calculator, you can instantly see how your combined figures stack up against HMRC’s £50,000, £30,000, and £20,000 rollout thresholds, whilst automatically stripping out exempt income such as limited company dividends and PAYE salary. Simply adjust the income sliders and click through the navigation tabs to receive a personalised compliance verdict, explore your quarterly reporting timeline, and test how the strict points-based penalty system applies from day one.
The penalty concession that Phase 2 entrants do not get
This is the point I want to flag most clearly, because the coverage of the first phase created an impression that does not carry through cleanly to the second.
HMRC's guidance on penalties for Making Tax Digital for Income Tax confirms that no penalty points are issued for a late quarterly update specifically during the 2026 to 2027 tax year. That concession was tied to that particular tax year, the first year the whole system operated, not to each taxpayer's individual first year of participation.
Someone brought into Phase 2 from April 2027 is starting their Making Tax Digital obligations in the 2027/28 tax year, which is not the concessionary year, so they are subject to the full points-based penalty regime from their very first quarterly deadline. HMRC's guidance on penalties for Making Tax Digital for Income Tax confirms the general mechanics: a penalty point for each missed quarterly update or tax return deadline, a £200 fixed penalty once four points accumulate, a further £200 for each subsequent miss while at that threshold, and automatic removal of points below the threshold after 24 months.
In other words, the softer landing that Phase 1 businesses enjoyed in their opening year is not a standing feature of joining Making Tax Digital, it was a one-off feature of the system's launch year. Phase 2 businesses should plan on the basis that their first quarterly deadline carries the same penalty exposure as their tenth.
The point that brings genuine relief for many small business owners
A large proportion of the "small business owner" audience this kind of article is aimed at trades through a limited company, and for that group there is a piece of good news that deserves equal billing alongside the Phase 2 detail, because it resolves a source of anxiety that has been circulating for years.
Making Tax Digital for Corporation Tax, which would have applied similar quarterly digital reporting obligations to companies, is not going ahead. HMRC's Transformation Roadmap, published in July 2025, confirmed that HMRC does not intend to introduce Making Tax Digital for Corporation Tax, and will instead modernise its internal Corporation Tax systems and develop a separate approach suited to the wide range of companies within the Corporation Tax population, from single-director consultancies to large groups. Limited companies continue filing their annual Company Tax Return on the existing CT600 basis, with no quarterly update obligation and no mandatory digital record-keeping requirement specific to Corporation Tax.
The distinction that matters here is between the company and the individual. If you run your business through a limited company and draw a salary and dividends, Making Tax Digital for Income Tax has no bearing on the company's own filing at all. It only becomes relevant to you personally if you separately have self-employment or property income outside the company, in your own name, that itself exceeds the relevant threshold. A director whose only income is salary and dividends from their own company is not brought into Making Tax Digital for Income Tax by that income at all, since dividends and employment income are not counted within the qualifying income test in the first place.
Where VAT fits into this picture
Making Tax Digital for VAT is a separate and already fully mature regime, worth distinguishing clearly from the income tax phases described above, since I regularly meet business owners who conflate the two. It has applied to VAT-registered businesses since April 2019, extended to effectively all VAT-registered businesses from April 2022, regardless of turnover.
The current VAT registration threshold stands at £90,000 of taxable turnover in any rolling 12-month period, with deregistration available once turnover falls below £88,000, a position confirmed in the House of Commons Library's briefing on VAT registration thresholds, which notes the threshold has been unchanged since it rose from £85,000 in April 2024. If you are already VAT-registered and filing digitally under Making Tax Digital for VAT, that obligation continues exactly as before and operates entirely independently of whichever Making Tax Digital for Income Tax phase you fall into.
Practical steps to take now if Phase 2 applies to you
● Confirm your 2025/26 qualifying income as soon as your figures are finalised, combining gross self-employment turnover and your own share of gross property income, rather than waiting for HMRC's confirmation letter.
● Do not assume a first-year penalty concession will apply to you. Build your quarterly reporting habits on the assumption that missed deadlines carry immediate points from day one.
● If you are close to the boundary, £28,000 to £34,000 of combined qualifying income is a sensible range to treat as effectively certain to be caught, given how income can move between the reference year and the year the phase actually starts.
● Choose compatible software now rather than in March 2027. Spreadsheet users need to confirm their spreadsheet can be digitally linked through bridging software, not simply exported and re-typed.
● If you run a limited company as well as having personal self-employment or property income, keep the two entirely separate in your planning. The company's Corporation Tax position is unaffected by any of this, and only your personal qualifying income determines whether Making Tax Digital for Income Tax applies to you.
Scotland and Wales
Making Tax Digital for Income Tax, Making Tax Digital for VAT, and the decision not to proceed with Making Tax Digital for Corporation Tax all apply uniformly across Scotland, Wales, England and Northern Ireland, since these are UK-wide administrative requirements set by HMRC rather than devolved matters. There is no separate Scottish or Welsh threshold, timetable or exemption regime for any part of Making Tax Digital.
The genuine point of difference for Scottish and Welsh taxpayers sits with the rate ultimately applied to the profit these systems report, not with whether or when the systems apply. Scottish Income Tax rates and bands, and Welsh Rates of Income Tax, both differ from the rest of the UK and apply to the profit figure your quarterly updates and final declaration produce, but they have no bearing on your qualifying income test or on which Making Tax Digital phase you fall into.
Key takeaways
● Phase 2 brings sole traders and landlords with qualifying income over £30,000 into Making Tax Digital for Income Tax from 6 April 2027, tested against the 2025/26 tax return that has already closed.
● Qualifying income is gross turnover, not profit, and combines self-employment and your own share of property income, so businesses with thin margins on a larger turnover are caught just as readily as more profitable smaller ones.
● The penalty concession that applied to late quarterly updates was specific to the 2026/27 tax year, not to each business's first year of participation, so Phase 2 entrants face the full points-based penalty regime immediately.
● Making Tax Digital for Corporation Tax has been formally ruled out by HMRC, so limited companies continue filing their CT600 exactly as before, entirely separately from any Making Tax Digital for Income Tax obligation an individual director may have personally.
● Making Tax Digital for VAT is a separate, already-mature regime applying to all VAT-registered businesses since April 2022, unaffected by the income tax phases.
● The rules apply identically across the whole of the UK; only the rate charged on the resulting profit differs by nation, not the reporting mechanism itself.
FAQs
When does MTD Phase 2 actually start, and who is affected?
Phase 2 starts on 6 April 2027 and applies to sole traders and landlords whose combined gross income from self-employment and property exceeded £30,000 on their 2025/26 tax return.
Is the £30,000 threshold based on profit or turnover?
Turnover, before expenses are deducted. A business or rental property with high costs and a modest actual profit can still be well over the £30,000 threshold and caught by Phase 2.
Will I get a penalty-free first year like the businesses that joined in Phase 1 did?
No. The concession that removed penalty points for late quarterly updates applied specifically to the 2026/27 tax year, the system's first year overall, not to each taxpayer's own first year of participation. Phase 2 entrants joining from April 2027 face the standard points-based penalty regime from their first quarterly deadline.
Does Making Tax Digital for Income Tax affect my limited company's Corporation Tax filing?
No. Making Tax Digital for Income Tax only applies to unincorporated self-employment and property income reported by individuals. Your company continues to file its Company Tax Return (CT600) as before, and HMRC has confirmed it does not intend to introduce a Making Tax Digital equivalent for Corporation Tax at all.
I am a director who only takes salary and dividends from my own company. Am I affected by Phase 2?
No. Salary and dividend income are not counted within the qualifying income test for Making Tax Digital for Income Tax, so a director with no separate self-employment or property income in their own name is not brought into scope by that income alone.
How is Making Tax Digital for VAT different from the income tax phases?
Making Tax Digital for VAT is a separate, long-established regime that has applied to effectively all VAT-registered businesses since April 2022, based on the VAT registration threshold of £90,000, and operates entirely independently of the income tax phase thresholds described here.
What if my income drops back below £30,000 after Phase 2 starts?
You remain within Making Tax Digital for Income Tax once a reference year has brought you into a phase. A subsequent quieter year does not remove the obligation, since the thresholds only ever add taxpayers into the system, they do not remove people whose turnover later falls.
Are partnerships included in Phase 2?
No. Partnerships remain outside Making Tax Digital for Income Tax for now, regardless of turnover, and no timetable for bringing them in has been announced.
What should I do right now if I think Phase 2 will apply to me from April 2027? Confirm your 2025/26 qualifying income as soon as your figures are complete, choose and start using compatible software well before the start date, and plan your record keeping on the assumption that missed quarterly deadlines will carry penalty points immediately, since no first-year concession applies to this phase.
