The MTD Penalty Points Expiry Clock: How Late-Update Points Fall Off

If you missed an MTD quarterly update, or you're worried you might, the first thing to know is that a single late one doesn't cost you a penny. It puts a point on your record — and that point isn't permanent. It has a shelf life.

That expiry clock is the part of the penalty rules that gets skipped over, and it's the part that should put your mind at rest. Under Making Tax Digital for Income Tax the penalties work on points, and points expire. This piece is about that clock specifically: how long a point lasts, when it drops off, and what that means for a bumpy first year.

A quick recap on points

When you're in MTD you send HMRC four quarterly updates a year, with deadlines on 7 August, 7 November, 7 February and 7 May. Miss one, and you get one penalty point. No fine attached to that point on its own.

A £200 charge only lands when you reach four points. And because there's no tax payment tied to a quarterly update, a late update can't trigger interest or a late-payment penalty either — those attach only to actual payment deadlines like 31 January. You can read the mechanics on GOV.UK's penalties for Making Tax Digital for Income Tax guidance.

One more thing worth knowing for the earliest years: voluntary participants who signed up before they were mandated aren't charged late-submission penalties in the first year. If you're not yet required to join but have volunteered, an early slip is even lower-stakes.

The 24-month clock

Here's the bit worth understanding properly. Each point you earn sits on your record for 24 months, then it expires — as long as you stay below the four-point threshold.

Think of it as a rolling window. A point earned in November 2026 is gone by November 2028, assuming you didn't hit four points in between. You don't apply for anything. You don't ring anyone. The point simply drops off after its 24 months are up.

That's the whole mechanism. There isn't a separate, faster "good behaviour wipes everything at once" shortcut for quarterly points — the reliable, published rule is the 24-month expiry, and each point runs its own clock. So if you've picked up two points at different times, they expire at different times too, each 24 months after the deadline it relates to.

A worked example: Nathan's messy year

Nathan lets out a flat in Bristol. His gross rent is over £50,000, so he's in MTD from 6 April 2026.

His first year is bumpy. He's changing jobs and moving house, and two deadlines slip past him.

• 7 November 2026 update: filed late. That's 1 point.
• 7 February 2027 update: also late. That's 2 points.

Two points, and Nathan has paid £0. No fine, no interest, nothing. He's rattled, but the damage is purely on paper.

Then he sorts himself out. He sets up reminders and files everything on time:

• 7 May 2027 update: on time.
• 7 August 2027, 7 November 2027, 7 February 2028: all on time.

He never reaches four points, so nothing is ever charged. The point from November 2026 expires around November 2028. The point from February 2027 expires around February 2029. Each one runs down its own 24 months and quietly falls off.

Nathan's takeaway: two missed deadlines in a stressful year cost him absolutely nothing, and his record cleared itself over time — no application, no phone call.

What actually costs money

So when does £200 arrive? Only at four points. To get there Nathan would need four late updates before any of the earlier points had expired — in practice, a full year of missed deadlines back to back, with nothing filed on time in between.

At that fourth point, the £200 is charged. After that, while you're still at the threshold, further late updates can each bring another charge until your points fall back below four as they expire. The way out is the same as the way to avoid it in the first place: file on time and let the clock run.

A note if you own with someone else

Points records are personal. If you own a property jointly, say with a partner, you each have your own record. One of you filing late doesn't put a mark against the other, and the four-point threshold is measured per person too. For more on splitting income and thresholds, see our guide to MTD for jointly owned property.

Putting a slip right

If you've missed an update, the fix is simple: file it as soon as you can. Because updates from 2025-26 are cumulative year-to-date totals, a late one still catches up the running figures, so filing it promptly keeps everything straight for the tax return due the following 31 January.

Good software takes most of this off your plate by nudging you before each deadline. Quarterwise sends reminders and files your quarterly updates and your tax return to HMRC, and the free plan for a single property has no card and no time limit — so a busy month is far less likely to turn into a missed deadline in the first place.

One late update is a wobble, not a disaster. Keep filing, let the 24 months tick over on each point, and your record clears itself.
