Making Tax Digital: The Rules Have Changed. Is Your Business Ready?
HMRC's landmark digital overhaul is no longer on the horizon — it's here. Here's what every sole trader and landlord needs to understand right now.
-
Making Tax Digital (MTD) is HMRC's programme to modernise the UK tax system. Rather than Jling a single annual Self Assessment return — a process many have used unchanged for decades — aPected taxpayers must now keep digital records and submit quarterly updates of their income and expenses directly to HMRC via approved soSware. MTD for VAT has been in force since 2019, and every VAT-registered business has operated under it since April 2022. What changes now is the extension of these rules to income tax — and the scope is sweeping.
IN PLAIN ENGLISH Instead of one tax return a year, you will need to maintain real time digital records and report to HMRC four times a year, plus a Jnal year-end declaration. Annual Self Assessment as you know it is being phased out.
-
MTD for Income Tax is being introduced in phases based on income thresholds. If you are self-employed, a sole trader, or receive income from property, check which wave you fall into:
APRIL 2026 — NOW £50k+ Combined income from self employment and/or property
APRIL 2027 £30k+ Threshold drops, bringing many more businesses into scope
APRIL 2028 £20k+ Announced at Spring Statement 2025 — millions of additional taxpayers
The threshold is based on your combined gross income from sole trades and property in the 2024/25 tax year. If you exceeded £50,000, you should already be operating under the new rules now. The 2028 expansion, confirmed by Chancellor Rachel Reeves in March 2025, means that by 2028 an estimated five million taxpayers will be covered
DON'T ASSUME YOU'RE SAFE YET Many landlords — particularly those who have never previously engaged with digital record-keeping — are not yet aware that MTD applies to property income. If you receive rent from one or more properties and your total qualifying income exceeds the threshold, you are in scope. Ignorance of the rules is not an exemption.
-
The obligations under MTD for Income Tax are substantially more demanding than the old Self Assessment regime. Here is what is now expected:
Digital Record-Keeping
All income and expenses from your self-employment or property must be recorded digitally — in real time, as transactions occur. Paper ledgers, spreadsheets not linked to HMRC-compatible software, and retrospective record updates at year-end are no longer permitted under the new rules.
HMRC-Approved Software
You must use software that is explicitly recognised by HMRC to record and submit your tax data. Providers such as QuickBooks, Xero, FreeAgent, and others offer MTD-compatible packages ranging from approximately £10 to £50 per month. Selecting the right software for your specific business structure is not straightforward — costs, features, and compatibility vary considerably.
Quarterly Updates
Quarter Period Covered Submission Deadline
-Q1 6 April – 5 July 2026 7 August 2026
-Q2 6 July – 5 October 2026 7 November 2026
-Q3 6 October – 5 January 2027 7 February 2027
-Q4 6 January – 5 April 2027 7 May 2027
Final Declaration
After the four quarterly updates, you must still complete a final year-end declaration, making any adjustments, claiming reliefs, and confirming your total tax liability.
For the 2026/27 tax year, this must be submitted by 31 January 2028. Importantly, you cannot submit this final declaration until all four quarterly updates have been submitted and confirmed.
"The move from one annual deadline to four quarterly submissions doesn't just quadruple your reporting obligations — it fundamentally changes how you need to manage your finances throughout the year."
-
HMRC has introduced a points-based penalty system for late submissions. While a 'soft landing' applies to the first cohort of taxpayers in 2026/27 — meaning no penalty points for late quarterly updates in the first year — this grace period will not extend to those who come into scope in 2027 or 2028. Understanding the penalty structure is essential:
Each late quarterly update or final return - 1 penalty point issued
Reaching 4 penalty points within 2 years - £200 Financial penalty
Late payment: 15 days overdue - 3% of outstanding tax
Late payment: 30 days overdue - 6% of outstanding tax
Late payment: 31+ days overdue - 10% per annum (accruing daily)
Late payment interest rate - 8.25% per annum
IMPORTANT NOTE ON THE SOFT LANDING
The penalty point exemption for late quarterly updates only applies to taxpayers mandated in April 2026. It is understood this leniency will not apply to those entering the system in 2027 or 2028. If you delay your preparation and fall into later cohorts, there will be no safety net.

The government has presented MTD as a simplification of tax reporting.
practice, for most taxpayers without professional support, the transition raises significant challenges that are easy to underestimate. Software Selection Is Not Trivial There are dozens of HMRC-compatible soSware providers, and choosing the wrong one — or failing to configure it correctly — can result in inaccurate submissions.
The software must align with your specific business type, whether you're a sole trader with multiple income streams, a landlord with jointly owned property, or both simultaneously. Jointly Owned Property Has Changed Rules Following consultation in Autumn 2023, HMRC amended the rules for jointly owned property reporting. The changes reduce some reporting requirements, but navigating what applies to your specific situation requires careful analysis of how income is split and reported.
Annualised Income Calculations Can Catch You Out If you started trading or receiving rental income mid-year, HMRC will annualise your income to determine whether you meet the threshold.
This means that even if your actual income in a partial year was below £50,000, your annualised equivalent could bring you into scope far sooner than expected.
No MTD for Partnerships — Yet Currently, the MTD regulations do not cover partnerships, though HMRC has conJrmed this extension is planned. If part of your income comes from a partnership, understanding what is and is not captured within the current rules is essential to avoid misreporting.
THE HIDDEN COST OF COMPLIANCE
Beyond software subscriptions of £10–50 per month, there is the cost of time: learning new systems, maintaining real-time records, and meeting four quarterly deadlines. For business owners whose time has real monetary value, outsourcing compliance to a qualified adviser is often more cost-effective than self-managing — and far less risky.
-
The shift to MTD is not simply a change of format — it is a fundamental restructuring of how the UK tax system operates. Where annual Self Assessment once provided a single defined moment of compliance, taxpayers are now operating in a continuous reporting environment, with four formal obligations per year and no margin for error once the soft landing period passes.
A qualified tax adviser brings more than just form-filling. They can analyse your specific income structure to confirm whether — and when — you are in scope. They can select and configure the right software for your circumstances.
They can manage your quarterly submissions, monitor for changes in thresholds or rules, and ensure your final declaration properly captures all available reliefs and adjustments. HMRC itself acknowledges that agents are well placed to help taxpayers understand the new obligations — particularly landlords, many of whom have no prior experience with digital reporting and may not yet realise the rules now apply to them.
THE ADVISER ADVANTAGE
With the 2027 and 2028 threshold reductions already confirmed, now is the time to establish a proper compliance structure — not when the first penalty point arrives. An adviser can ensure you enter the MTD regime correctly from the start, with systems in place that scale as the rules expand. The cost of professional advice is, in most cases, significantly less than the cumulative cost of penalties, interest, and time lost to self-managing a system that was designed with professional intermediaries in mind
The businesses and landlords who will navigate MTD most smoothly are not those who waited for HMRC letters to arrive — they are those who sought qualified guidance early, built the right digital infrastructure, and treated compliance as a year-round discipline rather than a January scramble. If you are not yet confident in your MTD compliance position, there is no better time to speak to a qualified tax adviser than now.
