HMRC digitised the tax system. It forgot to digitise the taxpayer.
Making Tax Digital’s first deadline lands on 7 August. Most of the people it affects still don’t know it’s coming — and the lesson reaches well beyond tax.
On 7 August, roughly 864,000 sole traders and landlords will find out whether Britain’s tax system was built with them in mind. That is the day the first quarterly update under Making Tax Digital for Income Tax falls due — HMRC’s most significant change to self-assessment in a generation, and the first hard deadline of a reform years in the making. On paper, the requirement is modest: a digital summary of income and expenses, filed through approved software, replacing part of the old annual paper trail. Research published by Sage in the weeks before the deadline found that only 37 per cent of those affected could correctly name the date.
I recognise this shape. Thirty years spent investigating financial crime, running technology organisations through regulatory upheaval, and building companies at the point where fintech meets the people who actually have to use it, teaches you one lesson above the rest: systems fail not at the point of design, but at the point of use, among the people nobody consulted while building them. Making Tax Digital is not a software rollout gone slightly wrong. It is what happens when an institution digitises its own machinery and calls that the whole job.
The evidence is not subtle. Research by IPSE and Sage last year found that only three in ten sole traders had a clear understanding of what MTD actually requires; a third were still keeping records on paper, two-thirds used spreadsheets, and more than half tracked income straight from bank statements. When Xero surveyed the same population as the April mandate took effect, 41 per cent said they were not ready, more than a quarter admitted they were behind schedule and unsure whether they would meet the August deadline, and one in seven had taken no action at all. Lloyds Banking Group’s research, drawn from sole traders already above the £50,000 qualifying threshold — the very group required to comply now — found that 55 per cent still had work to do.
HMRC’s logic for the reform is sound as far as it goes. The department estimates that avoidable errors and simple failures to take reasonable care account for up to £9 billion of the tax gap each year — the shortfall between tax owed and tax actually collected — and it believes real-time digital records will close much of it. But the scope only grows from here. The qualifying income threshold falls to £30,000 in April 2027 and to £20,000 in April 2028, pulling roughly 900,000 more people into a regime that the current, better-resourced cohort is still struggling to meet. Each drop reaches further into thinner margins, less accounting support and lower digital confidence — precisely the population least equipped to absorb a compliance shift alone.
This is the part policymakers consistently underfund. HMRC built approved-software standards, a penalty framework, and a soft-landing year in which no penalty points apply for late quarterly updates. What it did not build, at anything like the same scale, is a programme to raise the digital and financial capability of the people the reform depends on. Awareness campaigns are not capability. A leaflet explaining a deadline is not the same as teaching someone how to keep digital records, read what their software is telling them, or trust a number they did not calculate by hand. Britain treats financial and digital capability as a private responsibility, something individuals should already have or acquire in their own time, even as it builds public infrastructure that assumes they do.
I see the same failure across every domain where financial infrastructure goes digital, from open banking to the early architecture of digital money: the technical build gets funded, tested and delivered on schedule, while the capability to use it safely is left to the market, or to chance. That gap is the subject of the book I am completing on how states are choosing, often by default rather than design, who controls the movement of money and who is left to keep up. Making Tax Digital is a small, domestic, unusually well-documented version of that same choice. Britain has decided, again, that digitisation and capability-building can proceed on separate timetables. They cannot.
None of this argues for slowing MTD down. Quarterly digital records are a reasonable ask, and the tax gap they target is real money that other taxpayers effectively subsidise. But every threshold drop between now and 2028 will bring in people with less capacity to cope than the cohort filing this August, and government cannot keep treating that as someone else’s problem to solve after the fact. If HMRC and the Treasury are serious about a digital tax system, they need to fund capability with the same seriousness they fund compliance software — measured, resourced and owned, not left to accountants, banks and fintech firms to patch together after the deadlines have already landed. The 7 August deadline will pass quietly for most of Westminster. For most of the people it actually applies to, it will not.
