MTD Penalty Points Explained: How the System Works
Table of Contents
In short: Under HMRC's Making Tax Digital for Income Tax, each missed submission deadline (a quarterly update or the tax return) earns 1 point, and 4 points triggers a £200 penalty, with another £200 for each further miss at the threshold. Below the threshold, each point expires after 24 months. Late 2026-27 quarterly updates earn no points for those mandated from April 2026.
HMRC's MTD penalty points system works a bit like a driving licence: occasional lateness costs you nothing, but a pattern of it builds up to a real financial penalty. It replaced the old fixed late-filing fines for Making Tax Digital for Income Tax submissions, and it's different enough from what most people are used to from Self Assessment that it's worth understanding properly before you're relying on it.

How MTD penalty points actually work
Every missed submission deadline (a late quarterly update or a late tax return) earns you 1 point. A few things worth knowing about how points accrue:
- Points are capped at one per deadline. If you run more than one business, or have both self-employment and property income and file more than one update for the same period, you still only pick up a maximum of one point for that deadline, not one per business.
- Points sit against you as a taxpayer, not against an individual business.
- There's no financial cost to a single point on its own. This is the part that trips people up. A first or second late submission genuinely doesn't cost you anything directly.
The 4-point threshold: £200
Points only become expensive once you reach the threshold: 4 points triggers a £200 penalty. After that, every further missed deadline while you remain at the threshold adds another £200, not another point. The points total doesn't keep climbing past 4; the financial penalty becomes the deterrent instead.
| Missed deadlines | Points | Consequence |
|---|---|---|
| 1st | 1 | None |
| 2nd | 2 | None |
| 3rd | 3 | None |
| 4th | 4 | £200 penalty (threshold reached) |
| 5th and onward, while at threshold | Stays at 4 | Another £200 each time |
How points (and the £200s) go away
Below the threshold, each point simply expires after 24 months. Miss the 7 November deadline, and that point drops off two years later regardless of anything else you do.
Once you've hit the threshold, though, getting back to zero takes more than time passing. Two things have to happen together: 12 consecutive months of on-time submissions, and every submission that was outstanding across the prior 24 months brought fully up to date. Miss either condition and the points stay put, even if the 24-month clock on an individual point would otherwise have run out.
The first-year exception for 2026-27
If you were mandated into MTD from 6 April 2026, HMRC will not add penalty points for late quarterly updates during the 2026-27 tax year specifically. That gives anyone finding their feet in the first year some room. It's worth being precise about what it doesn't cover, though: your tax return is a separate deadline and still earns a point as normal if it's late, and late payment is penalised on its own tiered structure regardless of points. (The first return inside the points system is your 2026-27 return, due 31 January 2028. Your 2025-26 return, due 31 January 2027, still falls under the old Self Assessment penalties.) See what actually happens if you miss a quarterly update for the full breakdown of what the waiver does and doesn't protect you from.
Late payment sits outside the points system entirely
It's easy to conflate penalty points with late-payment penalties, but they're two separate mechanisms running in parallel. Points cover missed submissions: quarterly updates and the tax return. Paying tax late is penalised through its own tiered percentage structure:
| Days late | 2026-27 | 2027-28 |
|---|---|---|
| 0-15 days | No penalty | No penalty |
| 16-30 days | 3% of tax owed at day 15 (waived in your first year under MTD) | 4% of tax owed at day 15 (waived in your first year under MTD) |
| 31+ days | 3% at day 15 + 3% at day 30, then 10% a year charged daily from day 31 | 4% at day 15 + 4% at day 30, then 10% a year charged daily from day 31 |
Interest runs on top of all of this regardless of any penalty or waiver, currently 7.75% (base rate + 4%, from 9 January 2026). Nothing in the points system or the first-year waiver touches interest. It accrues on any unpaid tax from the day it was due.
Quick reference: which mechanism applies to what
| Mechanism | What triggers it | 2026-27 first-year treatment |
|---|---|---|
| Penalty points | Late quarterly update or late tax return | Quarterly updates: no points. Tax return: points apply as normal. |
| £200 penalty | Reaching 4 points | Not reachable from 2026-27 submissions: quarterly lateness earns no points, and a late return is a single point |
| Late-payment penalty | Paying tax owed late | 16-30 day tier waived; 31+ day tiers apply in full |
| Interest | Any unpaid tax | Always applies, with no waiver; currently 7.75% |
Frequently asked questions
How many penalty points before HMRC fines me under MTD?
Four. Each missed submission deadline earns one point, and at 4 points HMRC charges a £200 penalty, then another £200 for every further miss while you stay at the threshold.
Do late MTD quarterly updates get penalty points in 2026-27?
No. HMRC is not applying penalty points for late quarterly updates in the first year (2026-27) for those mandated from April 2026. Late tax returns and late payment are still penalised as normal.
How long do MTD penalty points last?
Below the threshold, each point expires 24 months after the missed deadline. At the threshold, resetting to zero requires 12 months of on-time submissions plus bringing any outstanding submissions from the previous 24 months up to date.
What are the late payment penalties under MTD for Income Tax?
For 2026-27: nothing up to 15 days late; 3% of the tax owed at day 15 if 16 to 30 days late (no penalty for this in your first year under MTD); 31+ days adds another 3% at day 30 plus 10% per year charged daily. From 2027-28 the two tiers rise to 4%. Interest (currently 7.75%) accrues on top throughout.
Staying under the threshold
Because the tax return is the only 2026-27 submission that can earn you a point, the single highest-value thing to get right is filing that return on time (by 31 January 2028), with figures drawn from records that were kept clean throughout the year. The waiver removes the point penalty for quarterly lateness. It doesn't remove the need for good records, since those same records are what your return depends on. Our first-year record-keeping checklist walks through building that habit from the start rather than trying to catch up in January.
Taxr won't file anything on your behalf (you'll still need MTD-recognised software or an accountant for that), but it handles the part that keeps you off HMRC's radar in the first place. Photograph a receipt and the AI extracts the vendor, date, total and VAT and suggests a tax-aligned category, so the expense figures in your quarterly updates and your return come from records that were accurate all along.
