Making Tax Digital Timeline: A Decade of Delays Explained
HMRC has postponed Making Tax Digital five times since 2015. Here is what the timeline actually reveals about who bears the cost of every delay.
HMRC first announced Making Tax Digital in December 2015, promising a "transformed tax system" by 2020. It is now 2025, and most sole traders are still filing an annual Self Assessment return. That gap between promise and reality is not an accident; it is a policy history worth understanding before April 2026 finally arrives.
- HMRC has delayed Making Tax Digital for Income Tax at least five times since 2015, each time citing complexity or the need to protect taxpayers.
- The April 2026 deadline applies to sole traders and landlords earning over £50,000; those earning over £30,000 follow in April 2027.
- Every delay has cost the Treasury estimated billions in uncollected tax, while software vendors have spent years building products sole traders now must buy.
- Understanding why deadlines have shifted helps you judge which current date is credible and plan accordingly.
- Voluntary sign-up is open now, meaning you can get familiar with quarterly submissions before they become compulsory.
If you have been vaguely aware that "some MTD thing" is coming but have never understood why the deadline keeps moving, this post is for you. The making tax digital timeline is not just a sequence of dates; it is a record of who pushed, who stalled, and who ultimately carries the administrative burden.
- Making Tax Digital for Income Tax
- HMRC's programme requiring sole traders and landlords to keep digital records and submit quarterly income and expenses updates via compatible software, replacing the annual Self Assessment return. The scheme is governed by the Income Tax (Digital Requirements) Regulations 2021.
2015 to 2017: The Original Vision
In December 2015, then-Chancellor George Osborne stood up and announced that the annual tax return would be abolished. HMRC published its Making Tax Digital roadmap in August 2016, setting out an ambitious timetable: VAT-registered businesses from April 2018, income tax from April 2018 for the largest businesses, with smaller taxpayers following by 2020.
The logic was compelling on paper. HMRC estimated it lost around £8 billion annually to avoidable taxpayer errors, the kind of mistakes that digital, real-time reporting would theoretically prevent. The Treasury Select Committee was less convinced. In early 2017, it called the rollout timeline "far too rushed" and questioned whether small businesses had been given adequate time to prepare.
In July 2017, HMRC blinked. The income tax element of MTD was postponed indefinitely. Only MTD for VAT would proceed as planned, applying to VAT-registered businesses with taxable turnover above the £85,000 VAT threshold from April 2019.
2019 to 2020: MTD VAT Launches, Income Tax Stalls
MTD for VAT went live in April 2019 for businesses above the threshold, and broadly it worked. There were teething problems: some software vendors were not ready, some accountants were overwhelmed, and HMRC quietly extended the "soft landing" period for digital links between software systems. But the programme did not collapse.
For sole traders below the VAT threshold, which covers a substantial proportion of the self-employed population, nothing changed. HMRC had originally indicated that income tax would follow VAT relatively quickly. Instead, consultations continued, pilot programmes remained small, and no firm legislative date was confirmed.
Then COVID-19 arrived in March 2020, and any remaining momentum evaporated. HMRC staff were redeployed to administer emergency schemes. The Self-Employment Income Support Scheme (SEISS) paid out over £28 billion to self-employed people during the pandemic. Introducing a new digital tax obligation in the middle of that crisis was politically unthinkable.
2021: Legislation Finally Arrives, With a 2023 Date
The Income Tax (Digital Requirements) Regulations 2021 gave MTD for Income Tax its first firm legal footing. HMRC announced a start date of April 2023, applying to sole traders and landlords with income above £10,000 per year. This was, by the standards of previous announcements, a genuinely broad mandate. A sole trader turning over £12,000 a year doing odd jobs at weekends would have been caught.
The pilot programme expanded cautiously. TapTax and other software vendors began building compliant products in earnest. Accountants started warning clients. And then, in December 2022, HMRC postponed again.
The reasons given were familiar: the economic environment (Britain was dealing with a cost-of-living crisis and soaring energy bills), concerns about taxpayer readiness, and feedback from accountants and software providers that more time was needed. The new date became April 2024, and the income threshold was raised: only those earning above £10,000 would be mandated, unchanged, but the rollout would be phased.
Within months, April 2024 was also abandoned. HMRC announced in December 2022 that April 2026 would be the new target, with a phased approach based on income levels.
The Current Making Tax Digital Timeline
This is where we stand today, and it is the most detailed and credibly supported version of the timeline HMRC has published.
April 2026: The First Wave
Sole traders and landlords with gross income above £50,000 must comply from April 2026. That means using HMRC-compatible software, keeping digital records from the start of the tax year (6 April 2026), submitting quarterly updates by the four statutory deadlines, and filing an End of Period Statement and Final Declaration in place of the traditional Self Assessment return.
If you are a plumber, electrician, or freelancer turning over £55,000 a year, this date applies to you. You cannot opt out. The four quarterly update deadlines HMRC will not forgive cover precisely what these submissions involve and when they fall.
April 2027: The Second Wave
Sole traders and landlords with gross income above £30,000 come into scope twelve months later. This second threshold is significant. It brings in a much larger population of self-employed people, including many part-time tradespeople and those with mixed income from employment and self-employment.
The £20,000 Threshold: Under Consultation
In the 2024 Autumn Budget, the government confirmed it intends to extend MTD to those earning above £20,000, with a provisional target of "by the end of this Parliament." No firm date has been legislated. If you earn between £20,000 and £30,000 from self-employment, you are in a holding pattern, but you would be unwise to assume the obligation will never arrive.
Why Has This Taken So Long? The Honest Answer
The official explanations, complexity, taxpayer readiness, economic conditions, have all played a role. But there are structural reasons why a programme announced in 2015 is still not fully operational in 2025.
First, HMRC underestimated the diversity of self-employed income. A freelance graphic designer with one client and a clean invoice trail is an entirely different compliance challenge from a market trader with cash sales, seasonal patterns, and shared van costs with a partner. Building a digital system that handles both fairly is genuinely hard.
Second, the software ecosystem was not ready in 2018, and HMRC chose not to build a free tool. As covered in detail in who really profits from Making Tax Digital software costs, the decision to mandate third-party software rather than provide a government portal created a commercial dependency. Vendors needed time to build products, and HMRC needed those products to exist before it could mandate their use.
Third, political appetite for imposing new burdens on small businesses has fluctuated. Every time a deadline loomed, the Federation of Small Businesses or the accountancy bodies would publish research showing that a large proportion of affected taxpayers had not heard of MTD, let alone prepared for it. Postponement became the path of least political resistance.
The cost of all these delays is borne by two groups: the Treasury, which forgoes the compliance improvements MTD is supposed to deliver, and software vendors, who have spent years developing products for a market that keeps failing to materialise on schedule. Ironically, when the mandate does finally land, those vendors will be the only ones ready.
What the Pattern Tells You About April 2026
Could April 2026 be delayed again? Truthfully, yes. But there are reasons to believe this iteration is more durable than its predecessors.
Legislation is already in place. The Income Tax (Digital Requirements) Regulations 2021, as amended, give April 2026 a statutory basis that earlier deadlines lacked. The pilot programme has been running for several years and has processed real submissions from real taxpayers. HMRC's systems have been tested in a way they simply were not in 2017 or 2019.
The income threshold of £50,000 is also politically shrewd. Targeting higher-earning sole traders first means the first wave covers a smaller, more administratively capable population. The accountancy profession is broadly prepared. Software is available at a range of price points, and as discussed in cheapest Making Tax Digital software: stop overpaying, it does not have to cost a fortune.
None of this is a guarantee. But if you are a sole trader earning over £50,000, planning on the basis of another postponement is a gamble that could leave you scrambling in early 2026.
What You Should Be Doing Right Now
The making tax digital timeline has a habit of catching people off guard precisely because the delays breed complacency. Here is what a rational sole trader does with this information.
If you earn over £50,000
April 2026 is eleven months away as this post is published. You need compatible software in place before 6 April 2026, and you need to understand what a quarterly update actually involves before your first deadline falls. Your MTD first quarterly update: what actually happens walks through exactly that.
Voluntary sign-up is open now through HMRC's pilot. Joining voluntarily means you practice the process without penalty risk. It also means your accountant, if you use one, can flag problems before they become compliance failures.
If you earn between £30,000 and £50,000
April 2027 is your date, but the smart move is to start keeping digital records now. Switching from paper or spreadsheets mid-year is disruptive. Starting clean at the beginning of the 2025/26 tax year costs you nothing and means you have a full year of digital data by the time you need to make your first submission.
If you earn between £20,000 and £30,000
No mandatory date yet, but the trajectory is clear. The government has stated its intention. Using this window to evaluate software, understand the quarterly cadence, and tidy up your record-keeping is time well spent. Check whether your current expenses claims are optimised too; sole trader expenses you are probably forgetting to claim is worth reading before you lock in any new system.

The Timeline in Brief
For anyone who needs the history at a glance:
- December 2015: MTD announced by Chancellor Osborne.
- August 2016: HMRC publishes full MTD roadmap with 2018 income tax start.
- July 2017: Income tax mandate postponed indefinitely; VAT-only proceeds.
- April 2019: MTD for VAT launches for businesses above the £85,000 threshold.
- 2021: Income Tax (Digital Requirements) Regulations 2021 set April 2023 as the income tax start date.
- December 2022: April 2023 postponed; new date April 2024, then immediately revised to April 2026.
- 2024 Autumn Budget: £20,000 threshold intention confirmed; April 2026 and 2027 dates reaffirmed.
- April 2026: Mandatory for sole traders and landlords earning over £50,000.
- April 2027: Mandatory for those earning over £30,000.
- By end of Parliament (TBC): Proposed extension to those earning over £20,000.
A decade of delays, and the bill for that procrastination, in software costs, in administrative upheaval, in the sheer cognitive load of tracking a moving target, has been paid by the same people it always is: the self-employed person trying to run a business and stay compliant at the same time.
April 2026 began as a promise made in 2015. That is a long time to wait. Do not give HMRC the opportunity to say you had ten years' notice and still were not ready.
