MTD for Income Tax Lands This Year. Here's What 7 August Means for a One-Van Operation.

It's a Tuesday in late May. You're a sole trader electrician, did about £60,000 last year, and you've always done your tax the same way: a shoebox of receipts, a spreadsheet if you're organised, one Self Assessment return every January. Your accountant sorts it, you pay the bill, you forget about it for eleven months.

That's over. From April 2026, if your trading income was above £50,000, you're in Making Tax Digital for Income Tax. Four quarterly updates a year, submitted through software, plus a final declaration. The first quarterly deadline is 7 August 2026.

If nobody's told you this yet, you're not alone. HMRC reckons around 860,000 sole traders and landlords are in the first wave, and a lot of them find out from their accountant in July.

The real cost

It's not the tax that changes. You'll pay roughly what you'd have paid anyway. What changes is the admin rhythm.

Instead of one annual scramble, you've got five touchpoints a year: four quarterly updates and an end-of-year declaration. Each quarterly update is a summary of your income and expenses for that three-month period, sent to HMRC through MTD-compatible software. Not a spreadsheet emailed to your accountant. Software that talks to HMRC directly.

That last bit is the catch. From April 2026 the software is mandatory. A shoebox of receipts and a January panic does not meet the requirement any more. You need your income and expenses in a digital format, kept up to date through the year, ready to summarise every quarter.

For a one-van operation that's a real shift. You're already doing the work: quoting, invoicing, buying materials. Now all of it has to leave a digital trail that maps to the four quarterly updates.

How most contractors handle it now

Three patterns, and two of them are about to break.

The shoebox. Receipts in the van, a carrier bag in the office, handed to the accountant in January. This does not survive contact with MTD. There's no digital record and no quarterly anything.

The spreadsheet. Better, but a spreadsheet on its own isn't MTD-compatible software. You'd need bridging software to get the figures to HMRC, and you'd still be updating it by hand four times a year.

The accountant does everything. Fine, until you realise quarterly filing means quarterly accountant involvement, and your once-a-year bill is now a four-times-a-year bill. Some accountants are repricing for exactly this.

How Field Forge handles it

The digital record isn't a separate job in Field Forge. It's a byproduct of running your work through the system.

Every quote you send, every invoice you raise, every purchase order and material cost you log, that's your income and expenditure captured as you go, in a digital format, categorised. When the quarterly update is due, the figures are already there. You're not reconstructing three months of receipts. You're reviewing a summary that built itself.

We're building the MTD quarterly export to line up with the HMRC submission categories, so the update is a review-and-send job, not a data-entry job. The maths is deterministic. AI doesn't touch the figures that go to HMRC. It just saves you the typing.

The point isn't that Field Forge does your tax. Your accountant still does that. The point is that the records HMRC now demands are a side effect of running your business properly, instead of a separate quarterly chore.

One thing you can do right now

Before anything else, find out if you're actually in scope. Go to GOV.UK and check the Making Tax Digital for Income Tax eligibility tool. If your 2024-25 trading income was over £50,000, you're in from April 2026 and your first quarterly update is due 7 August.

Then, whatever software you use, get your records digital before the first quarter closes. The contractors who find August painless are the ones whose income and expenses are already in a system today, not the ones starting from a shoebox in July.

You don't need Field Forge for that. You need to not be reconstructing three months of paperwork the week before a deadline you didn't know existed.
