How MTD penalties work and the £200 charge

You may have heard that Making Tax Digital comes with penalties, and worried about being fined for a single slip. The system is milder than the word "penalty" suggests, and most careful landlords will never pay a penny.

Other guides answer whether one late update is a fine (it isn't). This one does the arithmetic: how four points becomes a single £200 charge, and why late filing and late payment are two separate things. Here it is with pound figures.

One late update is a point, not a fine

Under MTD for Income Tax you send HMRC four quarterly updates a year, plus one tax return after the tax year ends. If you miss the deadline for a quarterly update, you get one penalty point. No money changes hands.

The deadlines for the standard quarters are 7 August, 7 November, 7 February and 7 May. Miss one and you have earned a point. That is all that happens for now.

The money only appears when you reach the threshold.

The £200 is charged at four points

For quarterly updates the threshold is four points. When you hit four, HMRC charges a single £200 penalty. Not £200 per point, not £200 per quarter. One £200 charge when your fourth point lands.

Because you only submit four quarterly updates in a tax year, four points means you have missed four quarterly deadlines, a full year's worth of updates. It does not sneak up on you after one forgetful week. You can read HMRC's own explanation on the MTD penalties guidance.

A worked example: how Sam reaches £200

Sam lets a two-bed flat and files his own updates. Life gets busy, and his year goes like this:

• He misses the 7 August update. 1 point.
• November comes round and he forgets again. 2 points.
• February, still not in the habit. 3 points.
• May, the fourth deadline slips too. 4 points, and now a £200 penalty.

The £200 only arrives because Sam missed four separate quarterly deadlines, every update he owed for the year. Each one had a reminder and a clear date. Any single quarter filed on time along the way and he would have stayed at three points with no charge.

His neighbour Jessica, who lets a similar flat, gets a reminder from her software a week before each deadline, files, and finishes the year on zero points. The difference between them is reminders.

Points don't stay forever

If you stay below the threshold, points expire after 24 months. An early wobble does not haunt you for life. Keep your record clean and old points drop off on their own.

Late filing and late payment are two different things

The points system covers late submissions, meaning the updates themselves. Your quarterly updates do not carry a tax payment, so missing one never triggers interest or a late-payment charge. A late update is only ever a point.

Late-payment penalties and interest are separate, and they attach to money deadlines. The main one is 31 January, when the tax for the year is due, the same date Self Assessment has always used. That is about paying HMRC, not filing an update.

A couple of things that help

A few points that apply to particular landlords.

If you join MTD before you are legally required to, you are not charged late-submission penalties in your first year. This grace covers late updates specifically, so payment deadlines still apply as normal.

Joint owners have separate records. If you and a partner own a property together, each of you has your own points count. Sam's late update does not put a point on Jessica's record.

Exempt taxpayers face no MTD penalties at all, because they are not in the system. Some landlords, for example those whose 2024/25 return included the SA109 residence pages, are automatically exempt for now and carry on with ordinary Self Assessment.

The takeaway

The penalty system is designed to catch repeated, sustained lateness, not a busy week. If you file your four updates roughly on time, you will never see a point, let alone the £200.

The best protection is a reminder that reaches you before each deadline. Quarterwise keeps your digital records, files each update to HMRC and prompts you ahead of every deadline. If you would rather have someone handle it, an accountant can file on your behalf too, and Quarterwise works alongside one.
