Making Tax Digital has been talked about for years, delayed twice, and surrounded by enough jargon to make most business owners tune out entirely. Now it’s actually here. From 6 April 2026, sole traders and landlords with qualifying income above £50,000 are legally required to comply with Making Tax Digital for Income Tax — and a second wave follows in April 2027 for those earning above £30,000.

We’ve had a lot of clients get in touch after receiving vague letters from HMRC using phrases like “you might need to” — which, understandably, has left people unsure whether this applies to them or not. It’s a reasonable reaction to unclear communication. But uncertainty isn’t the same as being exempt, and acting late will cause more stress than acting now.

This post sets out what’s actually changed, what the quarterly deadlines look like, and what the penalty picture means for the first year of compliance.

The first phase, which started on 6 April 2026, applies to self-employed individuals and landlords whose total qualifying income — that’s gross income, not profit — exceeds £50,000 per year. If you’re both self-employed and a landlord, the two income streams are combined when measuring against that threshold.

From April 2027, the threshold drops to £30,000, bringing in a second wave of sole traders and landlords. The government has confirmed that partnerships will be brought into the scheme at a later date, though no fixed date has been announced at the time of writing.

If you received one of HMRC’s “you might need to” letters and are unsure where you stand, the key question is straightforward: what was your total gross income from self-employment and/or property in the 2024–25 tax year? If it was over £50,000, you’re in scope now. If it was between £30,000 and £50,000, you have until April 2027 — but getting set up early makes the transition considerably easier.

Crucially, HMRC looks at gross income, not taxable profit. A sole trader turning over £60,000 with £15,000 of expenses is still above the £50,000 threshold, even though their taxable profit is £45,000. This catches people out more often than you’d expect.

One of the biggest sources of confusion is what a “quarterly update” actually is. It is not a full tax return submitted four times a year. Think of it more as a digital summary — a submission of your income and expenses for the quarter, sent directly to HMRC through MTD-compatible software.

The four submission deadlines each tax year are:

• 7 August 2026 — covering 6 April to 5 July
• 7 November 2026 — covering 6 July to 5 October
• 7 February 2027 — covering 6 October to 5 January
• 7 May 2027 — covering 6 January to 5 April

After those four updates, you still submit an End of Period Statement and a Final Declaration — the latter essentially replaces the annual Self Assessment return and remains due by 31 January following the end of the tax year. So 31 January isn’t going anywhere.

To submit quarterly updates, you need to keep digital records throughout the year using MTD-compatible software. HMRC-recognised tools include Xero, QuickBooks, and FreeAgent — all platforms we work with at Edward Harris. The key shift here is that keeping records in a spreadsheet and updating your accountant once a year no longer cuts it if you’re in scope. The records need to be live and digital as you go.

Here’s something genuinely useful to know: HMRC has confirmed there will be no penalties for missing quarterly update deadlines during the 2026–27 tax year. This is a deliberate soft landing, recognising that the first year is a transition period for businesses getting their systems and habits in place.

That said, we’d caution against reading “no penalties in year one” as “nothing matters in year one”. The habit of quarterly record-keeping needs to be built now, because from 2027–28 onward, a points-based penalty system applies to late submissions. Miss enough deadlines and the points accumulate — once you hit four points, a £200 penalty is triggered, with further penalties for ongoing non-compliance.

Late payment penalties are a separate matter and are not subject to the same soft landing. If tax is owed and remains unpaid, proportionate penalties begin to accrue after 30 days. So while HMRC is being lenient on the submission side in year one, the payment rules haven’t changed.

In our view, the sensible approach is to treat the first year as a genuine opportunity to get your processes right without the fear of an immediate fine — not as permission to delay. Getting your software set up and your quarterly rhythm established now means year two is smooth rather than a scramble.

It’s worth acknowledging that HMRC’s rollout communication has not been brilliant. Business owners across UK forums and small business communities have been sharing letters containing language along the lines of “you may need to sign up for Making Tax Digital” — which raises more questions than it answers. Does “may” mean you need to act? Does it mean you’re not sure yet? Does it mean HMRC doesn’t know?

The confusion is real, and it’s not a sign that business owners aren’t paying attention. It’s a sign that the communication could have been clearer.

There’s also a broader frustration worth noting. Survey data from the Administrative Burdens Advisory Board found that the majority of businesses in scope see limited benefit in the quarterly reporting regime — at least at this stage. We understand that view. For many sole traders who manage their finances reasonably well and submit a clean Self Assessment each January, the additional administrative layer feels like an imposition rather than an improvement.

Our honest take: MTD for Income Tax will, over time, encourage better bookkeeping habits and earlier visibility over tax liabilities. Whether that justifies the upfront admin cost is a legitimate debate. But the law is the law, and if you’re in scope, compliance isn’t optional — however imperfect the rollout has been. The best response to a poorly communicated rule change is to understand it clearly, not to wait and hope it goes away.

If you’re in scope for Making Tax Digital from April 2026 and haven’t sorted your setup yet, the list of what needs to happen is shorter than it might feel:

• Choose and sign up to MTD-compatible software. Xero, QuickBooks Online, and FreeAgent are all well-suited for sole traders and landlords. If you’re already using one of these, you may simply need to connect it to the MTD service via your Government Gateway.
• Register for MTD with HMRC. You need to sign up separately for MTD for Income Tax — being registered for Self Assessment doesn’t automatically enrol you. HMRC’s online service handles this.
• Establish a quarterly routine. The quarterly deadlines are predictable and spread through the year. Building a simple habit of reconciling your records at the end of each quarter makes each submission straightforward.
• Work with an accountant who handles this proactively. If you’re managing it alone, that’s fine for some businesses. But for those juggling a trade, a property portfolio, or both, having someone keep your digital records current and submit on your behalf removes the admin burden entirely.

At Edward Harris, we’ve been helping clients get MTD-ready and can manage the whole process — software setup, quarterly submissions, and the final declaration — as part of our ongoing support.
