What Is Making Tax Digital?

Making Tax Digital (MTD) is HMRC's programme to move the UK tax system online. You've probably already come across MTD for VAT — that's been around since 2019 and requires VAT-registered businesses to keep digital records and submit returns through approved software.

What's new in 2026 is MTD for Income Tax Self Assessment (MTD ITSA). This is a bigger change, and it affects sole traders — including plumbers, electricians, builders, gas engineers, roofers, and every other self-employed tradesperson — who earn above a certain threshold.

The headline change: instead of filing one Self Assessment return every January, you'll need to submit a summary of your income and expenses to HMRC four times a year, using approved software.

This is now live. MTD for Income Tax started on 6 April 2026. HMRC has described it as the biggest change to UK income tax reporting in over 30 years. If you're above the threshold, you need to act now.

Does It Apply to You?

MTD ITSA is being rolled out in phases based on your gross income — that's your total turnover before expenses, not your profit.

Phase Start Date Who's Affected
Phase 1 6 April 2026 — NOW Sole traders & landlords with gross income over £50,000
Phase 2 6 April 2027 Gross income over £30,000
Phase 3 6 April 2028 Gross income over £20,000

To check which phase applies to you, look at your 2024/25 Self Assessment return — specifically your gross self-employment income. That's the number that determines when you need to comply.

Important: If you have both self-employment income and rental income, HMRC combines them. A tradesperson invoicing £38,000 who also earns £15,000 renting out a property has qualifying income of £53,000 — which puts them in Phase 1 from April 2026.

What's Actually Changing?

Currently, you file one Self Assessment tax return each year before 31 January. Under MTD, this changes in three ways:

1. Digital record-keeping becomes mandatory

Paper records and spreadsheets you don't digitally link to HMRC are no longer acceptable. You must use MTD-compatible software to record your income and expenses as you go — not just at year end.

2. Quarterly updates replace the annual return

Every three months you'll need to submit a summary of your income and expenses to HMRC through your software. These aren't four separate tax returns — they're cumulative updates that build up over the year. The deadlines follow the standard UK tax year (April to April).

3. A Final Declaration replaces Self Assessment

At the end of the tax year, you make a Final Declaration — broadly similar to your current Self Assessment return — confirming everything is correct and claiming any allowances. This is due by 31 January as before.

Good news on penalties: HMRC has confirmed a soft landing for 2026/27 — penalty points won't be issued for late quarterly updates submitted within one month of the deadline. However, penalties for late Final Declarations and payment penalties apply from day one.

Why Does This Matter for Tradespeople Specifically?

Most trades work on a job-by-job basis — cash payments, card readers, BACS transfers, all mixed in. Keeping on top of which invoices have been paid, which haven't, and what you've spent on materials and tools throughout the year has always been a faff left until January. MTD kills that option.

Under the new system you need running records, not records you cobble together at year end. Every invoice you raise, every payment you receive, every material purchase — it all needs to be captured digitally and linked to your tax software.

If you're still invoicing by hand, on paper, or using a Word template you email as a PDF, now is the time to switch to a proper system.

What Do You Actually Need to Do?

  1. Check your qualifying income Look at your 2024/25 Self Assessment return. If your gross self-employment income (plus any rental income) exceeded £50,000, you're in scope from April 2026. If it was between £30,000 and £50,000, you have until April 2027.
  2. Choose MTD-compatible software HMRC maintains a list of approved software on GOV.UK. You need something that can keep digital records and submit quarterly updates directly to HMRC. Options range from full accounting packages like QuickBooks, Xero or FreeAgent, to simpler invoicing apps built for tradespeople. Check it's on HMRC's approved list before paying for anything.
  3. Start keeping digital records now Don't wait until your start date. The earlier you switch to digital records, the less painful the transition. Every invoice you raise and every expense you record from here on needs to be captured in your chosen software.
  4. Sign up for MTD ITSA Once you have your software, you need to sign up through GOV.UK before your start date. Your software will guide you through this, or your accountant can do it on your behalf. Don't leave this until the last minute — there can be delays.
  5. Tell your accountant If you use one, let them know. Accountants can access your MTD records and file on your behalf, but they need to know you're moving to the new system. Some accountants will handle the whole transition for you.

What Counts as an Allowable Expense?

Nothing changes here — the same expenses you've always been able to claim remain allowable. For tradespeople, this typically includes:

The difference under MTD is that you need to be recording these as you spend, not trying to remember them all in January. Keep your receipts and log them in your software as you go.

What Happens If You Ignore It?

HMRC is using a points-based penalty system. Each missed quarterly update earns one penalty point. Once you hit four points, you get a £200 fine — plus further £200 fines for every subsequent missed submission after that. Points expire after two years if you stay compliant.

The 2026/27 soft landing gives you some breathing room on quarterly deadlines, but it doesn't cover everything. The Final Declaration late filing penalty and payment penalties apply from day one — so don't assume HMRC is going easy on this.

Don't assume you're not affected yet. By 2028, the threshold drops to £20,000 — which will bring in nearly three million UK taxpayers. Most self-employed tradespeople will be in scope within two years. Getting set up now is far less stressful than scrambling at your deadline.

The Real Advantage: You'll Know Where You Stand All Year

Here's the thing most people miss. Yes, quarterly reporting sounds like more admin. But if you're using the right software, it's actually less work overall — because your records are always up to date.

Instead of spending a panicked weekend in January hunting for receipts and unpaid invoices from nine months ago, you'll have a running picture of your income, expenses, and rough tax liability every single month. For a tradesperson with a van, materials, and a steady stream of jobs, that kind of visibility is genuinely useful for managing cash flow.

The tradespeople who will find MTD painful are the ones who change nothing about how they record their work. The ones who will be fine are those who move their invoicing and expenses into a digital system now, before the deadline hits.

How TaskDrop Helps

TaskDrop generates professional, HMRC-compliant invoices and quotes via WhatsApp in under two minutes. Every document gets a sequential reference number, a proper VAT breakdown if applicable, and is saved to your dashboard — giving you a running digital record of every job you've invoiced.

While TaskDrop isn't an MTD submission tool itself (you'll still need MTD-compatible accounting software for your quarterly updates), keeping clean, dated, numbered invoices for every job you do is the foundation of good MTD compliance. If you can't show HMRC what you earned and when, the quarterly updates are meaningless.
