When does the £20,000 MTD threshold start?

Checked against GOV.UK on 14 August 2026 · Applies from 6 April 2028 onwards.

“As you only have two properties, just check that the income from that is over £50k pa. If not, you do not need to do MTD yet.”

We hear this most. a landlord telling another one to check before panicking, OpenRent Community forum, 31 July 2026 — someone in the same position as you.

Short answer
6 April 2028, tested on qualifying income over £20,000 on your 2026 to 2027 tax return.

If the answer turns out to be yes, these are the dates you inherit. Your next quarterly update is due 7 November 2026, and because updates are cumulative it covers 6 April to 5 October 2026 — so it also catches up 7 August 2026 if you missed it. Your tax return for 2026 to 2027 is due 31 January 2028, and that one is still in the points system. And from September 2026 HMRC has been signing people up itself, in stages, if they had not signed up.

You are not alone, and this is the measured version of that sentence. HMRC put 864,000 sole traders and landlords in scope for this tax year (HMRC, 5 February 2026), and reported on 12 August 2026 that 436,000 had sent a first quarterly update and 570,000 had signed up. We have not subtracted one from the other to make a "how many are behind" headline — they were published six months apart and count different things — but you can see the size of the room you are standing in.

What to do tonight

fifteen minutes, tonight, and it may end with you doing nothing at all

  1. Add your gross self-employment income to your gross property income, from the tax return you filed last. Before expenses. That total is the only figure that matters.
  2. Compare it against your year's line: over £50,000 on the 2024 to 2025 return means you are already in; over £30,000 on the 2025 to 2026 return means April 2027; over £20,000 on the 2026 to 2027 return means April 2028.
  3. If you are under the line, stop. There is nothing to apply for and nobody to ring — the exemption is automatic, and none of the rest of this page applies to you.

None of those three steps costs money. Anyone charging you to do them is selling you something HMRC gives away.

The free route, before anyone sells you a subscription

HMRC publishes the official list of software recognised for Making Tax Digital for Income Tax, and its own guidance says plainly that “free products are available for those with simple tax affairs”. We drove that finder ourselves on 1 September 2026 and it returns recognised products costing £0 — for sole traders and for landlords, including bridging tools that submit straight from a spreadsheet you already keep. We take no commission from any of them, we rank none of them, and this site carries no affiliate links.

The final announced phase reduces the mandation threshold to £20,000 from April 2028. Below £20,000, you are automatically exempt.

The £20,000 line, both ways

£20,000 does two jobs. Above it, from 6 April 2028, you are in Making Tax Digital. At or below it, HMRC's exemption guidance says you are automatically exempt — you do not apply, and you do not contact HMRC. That exemption is permanent unless your circumstances change.

What "circumstances change" means

The exemption tracks your qualifying income. If your gross self-employment and property income rises above the relevant threshold on a later return, you come into scope from the start of the following tax year. It is worth checking the figure each year rather than assuming a one-off answer holds.

If you are already in and your income falls

Once you are using the service, you can choose to opt out if your qualifying income has been below the relevant threshold for three tax years in a row.

Questions people ask

Am I exempt from MTD if I earn under £20,000?

If your qualifying income is £20,000 or less you are automatically exempt and do not need to apply. You still file a Self Assessment tax return as normal.

Some people who land on this page turn out not to be in Making Tax Digital at all, and I'd rather you found that out here in two minutes than after paying for a year of software. The threshold is gross and it's combined — turnover, both sources added together, before expenses. If that puts you under the line, there's nothing to apply for and nobody to ring. Close the tab with my blessing.
