Making Tax Digital Is Live — Your First Deadline Is 7 August

MTD for Income Tax came into force on 6 April 2026 for instructors earning over £50,000. The first quarterly submission is due 7 August. Here's the plain-English version: who's affected, what HMRC actually wants from you, and how to make it a non-event.

This is no longer a thing that's coming. It's here.

Making Tax Digital for Income Tax (MTD for ITSA) is HMRC's shift from one annual tax return to quarterly digital reporting. It came into force on 6 April 2026 for self-employed people with qualifying income over £50,000. A full-time instructor charging £40 an hour and teaching 30 hours a week grosses around £55,000 a year, so a large share of full-time ADIs are in scope right now, this quarter.

And the net widens. From April 2027 the threshold drops to £30,000, which catches nearly every full-time instructor in the country. From April 2028 it drops again to £20,000. If MTD doesn't apply to you yet, it almost certainly will within two tax years.

The rules are blunt: you cannot submit quarterly updates on paper, and you cannot email HMRC a spreadsheet. You need digital records and MTD-compatible software to file.

The dates that now matter

Your tax year is split into four quarters, each with its own submission deadline:

• Quarter 1 (6 April – 5 July) — submit by 7 August 2026. That's the one coming at you now.
• 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 the four quarterly updates you still do a final declaration by 31 January, much like the old return. So MTD isn't replacing your January deadline. It's adding four more on top.

One mercy: each quarterly update is cumulative from 6 April, so a mistake in one quarter is simply corrected by the running total in the next. And HMRC has confirmed a soft-landing on penalties this first year. But don't let that lull you — the penalty system is points-based (a point per late submission, £200 fine when you reach four points), and the record-keeping requirement applies from day one. The instructors who treat 2026/27 as a practice year with real records will find 2027/28 effortless. The ones who don't will be the ones panicking in the Facebook groups next spring.

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 now need your data four times a year instead of once. Quarterly processing of a shoebox costs more than quarterly processing of clean records — how tidy your records arrive is now directly a line on their invoice.
• Nothing? You're not alone, but the first deadline is 7 August. This is the quarter to fix it.

MTD is not optional. The penalty regime is points-based: each late quarterly submission earns a point, and at four points you get a £200 fine. The first year has a soft-landing on late-submission points, but the obligation to keep digital records started on 6 April and isn't suspended.

What you actually need to do

1. Check whether you're in scope. Qualifying income is your gross self-employment (plus any property) income, not your profit. Over £50,000 in 2024/25 means you're in now; over £30,000 means you join in April 2027.
2. Sign up for MTD with HMRC. Through your Government Gateway account, before your first quarterly submission is due.
3. Sort your filing route. If you have an accountant, they almost certainly file for you and just need clean quarterly data. If you don't, HMRC maintains a list of MTD-compatible software, from free basic tools to full packages.
4. Start keeping digital records now. Every lesson payment. Every fuel receipt. Every insurance renewal. Quarterly, not annually — and the carrier bag doesn't count.
5. Set aside tax money monthly. A separate savings account, 25–30% of income moved in each month. When the bill comes, the money is there.

How PassReady handles this (free)

PassReady is a free diary and booking platform for driving instructors, and the part that matters here is a quiet side effect: running your diary in it does your record-keeping for you.

• Income records itself. Every lesson you teach is already an income entry — online bookings carry their card-payment reference automatically, and cash or bank-transfer lessons are logged in seconds.
• Expenses go in the right boxes. Seventeen instructor-specific categories, each mapped to the correct HMRC self-employment box. Snap a photo of the receipt at the pump and it's attached and stored.
• Mileage calculates itself from your lesson postcodes — useful evidence whichever claiming method your accountant uses.
• Your car purchase is recorded properly. Dual-control vehicles are plant and machinery, so the purchase is logged as a capital record, flagged for your accountant rather than mixed into your expenses.
• Quarter end is one tap. A records checklist shows what's in place, and the Tax Pack download bundles everything — income in formats Xero, QuickBooks, FreeAgent and Sage import natively, expenses by HMRC category, the mileage log, receipt photos, an HMRC-formatted quarterly summary, and a ready-to-send pack for your accountant. You'll get a reminder email before every deadline with the pack one tap away.

To be completely clear about what it doesn't do: PassReady doesn't give tax advice and doesn't file with HMRC — your accountant or your MTD filing software does that, using the records PassReady hands them. The aim is simply that the quarterly deadline everyone dreads takes you a couple of minutes, and your accountant's quarterly bill reflects clean records instead of archaeology.
