Making Tax Digital Starts April 2026 — Are You Ready?

MTD for Income Tax is mandatory from 6 April 2026 for instructors earning over £50,000. Quarterly digital reporting to HMRC. Here's what you need to know and how to prepare.

What is Making Tax Digital?

Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) is HMRC's shift from annual tax returns to quarterly digital reporting. Instead of one big return in January, you'll submit income and expense summaries to HMRC four times a year using compatible software.

From 6 April 2026, it's mandatory for self-employed individuals and landlords with income over £50,000. From April 2027, the threshold drops to £30,000. If you're a full-time driving instructor earning above those numbers, this affects you directly.

You cannot submit quarterly updates on paper. You cannot use a spreadsheet emailed to HMRC. You need HMRC-compatible software that submits digitally.

What quarterly reporting actually means

Under MTD, your tax year is split into four quarters. At the end of each quarter, you submit a summary of your income and expenses to HMRC through your software. The deadlines are roughly:

• Quarter 1 (6 April – 5 July) — submit by 7 August
• Quarter 2 (6 July – 5 October) — submit by 7 November
• Quarter 3 (6 October – 5 January) — submit by 7 February
• Quarter 4 (6 January – 5 April) — submit by 7 May

After all four quarterly updates, you submit a final declaration (similar to the current self-assessment return) by 31 January the following year. So it's not replacing the annual return — it's adding four submissions on top of it.

The driving instructor tax trap most people don't know about

Here's something that catches a lot of instructors out. You cannot claim the standard mileage allowance.

Most self-employed people can claim 45p per mile for the first 10,000 miles and 25p after that. It's simple. But HMRC classifies dual-control driving instruction vehicles as Plant and Machinery, not ordinary cars. That means the simplified mileage rate doesn't apply to you.

Under MTD, you need these numbers quarterly. Not annually. Quarterly. If you're currently keeping receipts in a carrier bag and totalling them up in January, that won't work anymore.

The first year tax shock

If you're newly self-employed or moving to self-assessment for the first time, there's a nasty surprise waiting in your first tax bill. It's called payment on account.

Here's how it works. Say your tax bill for the year is £10,000. You'd expect to pay £10,000. But HMRC also charges 50% of your estimated next year's bill upfront. So your first payment is actually £15,000 — the full £10,000 plus a £5,000 advance.

This catches people every year. Instructors who've been working PAYE for a franchise and then go self-employed are particularly vulnerable. You've had a year of not setting money aside for tax, and then HMRC asks for 150% of what you expected.

Under MTD, the quarterly visibility should help you see this coming. But only if you're actually looking at the numbers each quarter and not just clicking "submit" blindly.

What most instructors are doing now (and why it won't work)

Be honest with yourself. How are you tracking your business finances right now?

• Spreadsheet? That's fine for your own records, but it won't submit to HMRC under MTD. You need software that connects to HMRC's API.
• Carrier bag of receipts? Not quarterly-compatible. You know this.
• Your accountant handles everything? They still will, but they'll need data from you more frequently. And they'll charge more for quarterly processing.
• Nothing? You're not alone, but April is two weeks away.

MTD is not optional. HMRC will issue penalties for late quarterly submissions and inaccurate data. The penalty regime uses a points-based system — you accumulate points for late submissions, and when you hit the threshold, you get fined.

What you actually need to do

1. Sign up for MTD with HMRC. You need to register before your first quarterly submission is due. Do this through your Government Gateway account.
2. Get compatible software. HMRC maintains a list of MTD-compatible software. It ranges from free basic tools to full accounting packages.
3. Start tracking income and expenses properly. Every lesson payment. Every fuel receipt. Every insurance renewal. Quarterly, not annually.
4. Set aside tax money monthly. Open a separate savings account. Move 25-30% of your income into it each month. When the bill comes, the money is there.

How PassReady helps

PassReady has built-in expense tracking designed for driving instructors. You log fuel purchases, maintenance costs, insurance, and other business expenses directly in the app. It categorises everything correctly for HMRC — no guessing about which expenses go where.

Fuel logging is automatic when you record it at the pump. Tax estimates update in real time so you can see roughly what you'll owe before the quarter ends. No January surprises. No scrambling for receipts.

It won't replace your accountant. But it means when your accountant asks for your quarterly figures, you can export them in seconds instead of spending a weekend with a shoebox.
