MTD for income tax
If the phrase Making Tax Digital for Income Tax makes your stomach tighten, you’re not alone. Thousands of sole traders and landlords across the UK are wondering what it means for their business, their software, and their sanity. The good news? With a little preparation, MTD for Income Tax is genuinely manageable — and this guide will walk you through exactly what’s changing, when, and what to do about it.
What is MTD for Income Tax?
Making Tax Digital for Income Tax Self Assessment (often shortened to MTD for IT or MTD ITSA) is HMRC’s plan to modernise the way self-employed people and landlords report their income. Instead of submitting one Self Assessment return each year, affected taxpayers will keep digital records and send quarterly updates to HMRC through compatible software, followed by a final declaration after the tax year ends.
The government’s reasoning is straightforward: digital, more frequent reporting should reduce errors, close the so-called “tax gap”, and give people a clearer picture of what they owe in real time rather than a nasty surprise in January. Whether you agree with the policy or not, it’s happening — so understanding the detail matters.
MTD for VAT has already been in place for several years and is now standard practice for VAT-registered businesses. MTD for Income Tax is the next major rollout, and it will eventually affect millions of sole traders and landlords.
Who is affected and when?
This is where many people get confused, because the dates and thresholds have shifted more than once. Here is the position as set out by HMRC at the time of writing — we always recommend confirming current details on the official GOV.UK Making Tax Digital pages.
The phased rollout
- From 6 April 2026: Sole traders and landlords with qualifying income above £50,000 must comply with MTD for Income Tax.
- From 6 April 2027: The threshold drops to £30,000 of qualifying income.
- From 6 April 2028: The threshold is set to fall further to £20,000, bringing many more sole traders into scope.
“Qualifying income” means your gross income from self-employment and property before expenses — not your profit. So a sole trader turning over £55,000 but earning a £28,000 profit would still be in scope from April 2026.
Partnerships, companies, and those in formal HMRC exemption categories sit outside the current rollout, although MTD for partnerships is expected at a later date.
The key changes you need to know
1. Digital record-keeping
Paper ledgers and shoeboxes of receipts will no longer cut it. You’ll need to record your income and expenses digitally, using MTD-compatible software or a bridging tool linked to a spreadsheet. Records must be kept as they happen — not reconstructed at year-end.
2. Quarterly updates to HMRC
Four times a year, you’ll send a summary of your income and expenses to HMRC through your software. These aren’t full tax returns — they’re cumulative snapshots that help HMRC (and you) see your position throughout the year. The standard quarters run to 5 July, 5 October, 5 January and 5 April, with submission deadlines roughly one month after each quarter ends.
3. The final declaration
At the end of the tax year, you’ll submit a final declaration, which replaces the traditional Self Assessment return. This is where you confirm your figures, add any adjustments (such as capital allowances or private use), and declare other income like dividends, interest or employment earnings. The deadline remains 31 January following the end of the tax year.
What does “MTD-compatible software” mean?
MTD-compatible software is any product approved by HMRC that can keep your digital records and send your quarterly updates and final declaration through HMRC’s systems. Popular options include Xero, QuickBooks, FreeAgent, Sage and a growing list of MTD-focused tools designed specifically for sole traders and landlords.
If you prefer spreadsheets, you can still use them — but they’ll need to connect to HMRC via bridging software, which acts as a digital link between your figures and HMRC.
Choosing the right tool depends on your needs. A landlord with two properties has very different requirements from a builder running a busy trade. As part of our bookkeeping and tax services, we help clients pick software that genuinely suits how they work, rather than the most heavily marketed option.
Practical steps to take now
The worst thing you can do is wait until the deadline looms. Here’s a sensible order of action:
- Check your turnover. Look at your most recent Self Assessment. If your combined self-employment and property income is heading towards £50,000, £30,000 or £20,000, work out which start date applies to you.
- Move away from paper. Even before MTD bites, switching to digital record-keeping will save you time and reduce errors.
- Choose your software. Pick an MTD-compatible product and get comfortable with it well before your start date.
- Tidy up your bookkeeping habits. Reconcile your bank account regularly, separate business and personal spending, and capture receipts as you go.
- Talk to your accountant. A short conversation now can save hours of stress later. Our team at Melon Accountants is already helping clients map out their transition.
Common worries — and honest answers
“I’ll have to do four tax returns instead of one.”
Not quite. Quarterly updates are lightweight summaries, not full returns. If your bookkeeping is up to date, each submission should take minutes rather than hours.
“I’m not tech-savvy — I’ll never cope.”
Modern accounting software is built for non-accountants. Bank feeds, receipt scanning and automatic categorisation do most of the heavy lifting. And if it still feels daunting, you don’t have to face it alone — that’s what we’re here for.
“Will my tax bill go up?”
MTD doesn’t change the rules on what’s taxable or how much tax you pay. It changes how you report. That said, more accurate, regular records often surface deductions people would otherwise miss, so some clients actually end up better off.
“What if I’m under the threshold?”
You can stay on the current Self Assessment system for now, but you can also opt in voluntarily. For some sole traders, joining early provides a smoother glide path and avoids a last-minute rush.
The benefits, not just the burden
It’s easy to focus on the hassle, but there are real upsides to MTD for Income Tax once you’re set up:
- Fewer year-end surprises. Quarterly visibility means you’ll know roughly what tax you owe long before January.
- Better business decisions. Up-to-date numbers help you price jobs, manage cash flow and plan investments.
- Reduced errors. Digital records and automatic calculations mean fewer mistakes and fewer HMRC nudge letters.
- Easier finance applications. Lenders increasingly expect cloud-based, real-time figures.
It is, of course, a genuine change in routine — and for sole traders who have always handled their own tax with a folder and a calculator, it’s a meaningful shift. We won’t pretend otherwise. But it’s far from insurmountable.
