Making Tax Digital for Income Tax has arrived. From 6 April 2026, sole traders and landlords with total annual income above £50,000 are legally required to keep digital records and submit quarterly updates to HMRC — replacing the old once-a-year Self Assessment routine most people are used to.

We’ve had a lot of conversations with clients over the past few months who are either unsure whether MTD applies to them, or who know it does but haven’t quite got round to doing anything about it. Both groups are running out of runway. The first quarterly update deadline falls on 7 August 2026 — which is closer than it feels.

This post sets out what MTD for Income Tax actually requires, the dates that matter most right now, and the practical things worth getting right from the start. We’ll also share our honest view on where this change creates genuine risk, and where the concern is mostly noise.

The current mandate covers sole traders and landlords whose total qualifying income exceeds £50,000 per year. Qualifying income includes self-employment income and property rental income — these are added together if you have both.

So if you run a trade as a sole trader and also receive rental income from a property, both streams count towards that threshold. If your combined total is over £50,000, you’re in scope from 6 April 2026.

The threshold drops to £30,000 from April 2027, and a further expansion is expected in subsequent years, so even if you’re currently below the limit it’s worth keeping an eye on this.

Limited companies are not affected by the current MTD for Income Tax rules — this obligation sits with individuals filing Self Assessment returns, not with companies filing Corporation Tax. If you operate through a limited company and pay yourself a salary or dividends, MTD for Income Tax doesn’t apply to that company income.

If you’re genuinely unsure whether you’re in scope, the starting point is your most recent Self Assessment return and whether your total self-employment and property income across all sources exceeds the threshold.

The transition to MTD for Income Tax isn’t a single event — it unfolds across a schedule of deadlines, and missing the early ones creates problems down the line.

• 6 April 2026 — the obligation starts. Digital record-keeping using MTD-compatible software should have begun from this date for in-scope individuals.
• 7 August 2026 — deadline for the first quarterly update (covering April to June 2026).
• 7 November 2026 — deadline for the second quarterly update (covering July to September 2026).
• 31 January 2028 — deadline to file the finalised tax return for the 2026/27 tax year, submitted directly through MTD software rather than via the old Self Assessment portal.

The quarterly updates themselves aren’t a full tax return — they’re a summary of income and expenses for the period. But they do need to be submitted through HMRC-recognised MTD software, which means having the right tools in place before that 7 August deadline arrives.

If you haven’t yet signed up for MTD for Income Tax and set up compatible software, that’s the most pressing thing to address. HMRC’s sign-up rates for this cohort have been reported as low, which suggests a lot of people are leaving this very late.

HMRC’s stated intention with MTD is to reduce errors in tax reporting — the theory being that more frequent, smaller updates catch mistakes before they compound across a full year. That logic is reasonable in principle.

In practice, though, moving from one annual filing to four quarterly updates plus a final return does create more opportunities for things to go wrong, not fewer. Each submission is another chance to miscategorise an expense, omit an income stream, or fall foul of a software issue. There’s also the practical reality that some MTD-compatible software platforms have had teething problems — security updates locking users out of their accounts, sync issues with bank feeds, and similar frustrations that are genuinely disruptive if they hit close to a deadline.

Our view is that the risk isn’t in the concept of quarterly reporting itself — it’s in approaching it without a reliable process. Someone who has always done their own bookkeeping informally in a spreadsheet and left everything to their accountant in January faces a meaningful shift. That annual scramble doesn’t translate well into a quarterly cadence.

The clients we see managing this most comfortably are those who’ve moved to cloud accounting software — Xero, QuickBooks, or FreeAgent — and kept their records reasonably tidy throughout the year. For them, MTD adds a submission step to something they were already doing. For everyone else, it adds a process change on top of a software change, which is where the stress tends to build.

There’s a reasonable debate to be had here. Some prominent accountancy commentators have argued that MTD for Income Tax will generate no meaningful additional tax revenue for the Treasury, while loading a significant compliance burden onto self-employed people and landlords who are already stretched. That critique isn’t entirely unfair.

That said, we think the framing of ‘pointless admin’ misses something. For business owners who’ve historically had a chaotic relationship with their finances — invoices in a drawer, receipts on a phone, a vague sense of what they owe come January — the discipline of quarterly reporting can actually be useful. Not because HMRC asked for it, but because knowing where you stand every three months is genuinely better than finding out in November that you owe more than you expected.

The businesses that struggle most with Self Assessment every January aren’t the ones with complicated finances — they’re the ones who’ve left everything untouched since the previous year. MTD doesn’t fix poor habits automatically, but it does create a structure that makes it harder to ignore your numbers for twelve months straight.

Whether that justifies the compliance cost is a fair question. Our honest answer: if you’re going to be in this system regardless, the approach that makes it work for you is worth finding.
