MTD Penalties Explained: The Simple Guide to the New Points System

For years, the phrase "HMRC penalty" has usually conjured up the image of an automatic £100 fine the moment you miss a Self Assessment deadline. But as we move into the era of Making Tax Digital (MTD) for Income Tax, the rules are changing.

Starting in April 2026, the old automatic fines are being replaced by a fairer, but potentially more cumulative, points-based system. If you are a sole trader or a landlord with a qualifying income over £50,000, this system is about to become your new reality.

In this guide, I’m going to break down exactly how these points work, how they turn into £200 fines, and the "reset" mechanism HMRC has put in place to help those who get back on track.

What is the MTD Points-Based Penalty System?

HMRC is moving away from immediate punishment. Instead, the new regime is designed to target "persistent" non-compliance while giving a bit of leeway to the occasional mistake. Think of it like penalty points on a driving licence: one slip-up won't cost you your licence, but a pattern of speeding eventually leads to a ban (or in this case, a bill).

Under MTD for Income Tax, you are required to send quarterly updates of your business income and expenses to HMRC. You also need to submit a "Final Declaration" at the end of the tax year. Each time you miss one of these deadlines, you "earn" a point.

How the Points Become Fines

A point on its own doesn't cost you anything. However, once you hit a certain "threshold" of points, HMRC will issue a £200 fine.

For most SME owners and landlords mandated for MTD, the magic number is 4 points.

• 1st Late Submission: 1 point (No fine)

• 2nd Late Submission: 2 points (No fine)

• 3rd Late Submission: 3 points (No fine)

• 4th Late Submission: 4 points (£200 fine issued)

• Every late submission after 4 points: Another £200 fine

Because MTD requires four quarterly updates plus one final declaration per year, a business that completely ignores their filing obligations could find themselves racked with £1,000 in fines in a very short space of time.

The 2026/27 Grace Period: A Vital Easement

There is some good news for those joining the scheme in the first wave. HMRC understands that transitioning to digital record-keeping and quarterly filing is a big step.

For the first year of the mandate (the 2026/27 tax year), HMRC has introduced a 12-month easement. This means that while you are still legally required to submit your quarterly updates, you will not receive penalty points if those quarterly updates are late during that first year.

However, be warned: the Final Declaration (the end-of-year return) for 2026/27 is not part of this grace period. If you miss that deadline on 31 January 2028, you will start collecting points.

A Quick Reference: The Penalty Table

To keep things simple, here is how the points stack up for a typical quarterly filer:

Number of Late Submissions	Penalty Points Total	Penalty Charge
1	1	£0
2	2	£0
3	3	£0
4	4 (Threshold Hit)	£200
5	4 (Stays at threshold)	£200
6	4	£200

Note: Even if you have multiple businesses or properties, you can only receive one point per deadline.

How Do You Reset Your Points?

Unlike driving licence points that eventually expire after a fixed time, MTD points only expire if you stay below the threshold for two years.

If you have already hit the threshold and received a fine, the only way to "zero out" your points is through a Period of Compliance. For quarterly filers, this means:

1. 12 months of on-time filing: You must submit all quarterly updates and your Final Declaration on time for a full year.

2. Clean the slate: You must ensure all outstanding returns from the previous 24 months have been submitted.

Once you meet both criteria, your points total resets to zero.

Is Your Business Ready?

The move to MTD isn't just about avoiding points; it's about changing how you manage your business finances. Moving from a once-a-year "shoebox of receipts" approach to a "digital-first" quarterly approach is a significant shift.

If you're feeling overwhelmed by the upcoming changes, you aren't alone. We recently explored the wider implications of this transition in our guide: Is your business ready for the MTD cliff edge?

Why a Specialist Accountant is Your Best Defence

The easiest way to avoid the "points trap" is to have a professional managing the schedule for you. At Accountant Search, we specialise in matching SMEs and self-employed professionals with accountants who are MTD-ready.

A dedicated tax advisor doesn't just file your returns; they ensure your digital software (whether it’s Xero, QuickBooks, or an Excel bridging tool) is set up correctly so that quarterly updates become a five-minute task rather than a week-long headache.

If you are looking for expert SME Tax Services to help navigate these new rules, we can match you with a vetted professional in your sector within minutes.

Summary: Stay Ahead of the Points

The new system is fairer for the occasional late filer, but it is much stricter for those who fall behind and stay behind. By the time April 2027 rolls around and the income threshold drops to £30,000, millions more people will be under this regime.

Don't wait until you're at 3 points to seek help. Setting up the right processes now means you can focus on growing your business while your digital tax obligations run smoothly in the background.
