The HMRC’s new points-based penalty system changes the risk profile for self-employed people and landlords. From April 2026, compliance is no longer just about meeting one annual deadline. It becomes a year-round discipline built around digital records, quarterly submissions, a final declaration, and prompt payment. Miss the filing side often enough and points build up. Miss the payment side and a separate financial penalty can follow. That is the penalty double.

What the latest points-based penalty system means in practice
The old pattern of annual self-assessment encouraged many taxpayers to think about compliance once a year. The new regime changes that. HMRC says the first mandated MTD for Income Tax group joins from 6 April 2026 if their qualifying income is over £50,000, and points-based late submission rules apply from the tax year a person joins MTD. HMRC also says there are around 864,000 individuals in that first group.
For most people, the practical change is this: compliance becomes process-driven. Digital records must be kept throughout the year, and submissions need to be managed in sequence, not left until January. That is why strong bookkeeping services become a preventative tool.
Why Making Tax Digital penalties create a “penalty double”
The structure for Making Tax Digital penalties matters because late submission and late payment are now clearly separated.
If you miss a submission deadline, you could receive a penalty point. Once you reach the threshold, which for MTD for Income Tax is four points, you get a £200 penalty. After that, every further missed submission triggers another £200 penalty.
If you also fail to pay the tax due on time, a second penalty track can apply. That means one weak internal process can create two different financial consequences.
The risk in 2026 is not one missed task. It is a weak filing and payment process repeated across the year.
Who is affected by MTD penalties
MTD for Income Tax becomes mandatory from 6 April 2026 for people with qualifying income over £50,000 from self-employment, property, or both. The threshold falls to £30,000 from 6 April 2027 and to £20,000 from 6 April 2028.
| What changes | What it means in practice |
| Digital record-keeping | You need usable, current records all year |
| Quarterly updates | Deadlines become recurring, not annual |
| Final declaration | Year-end accuracy still matters |
| Late payment penalties | Paying late can trigger a separate charge |
How HMRC late payment penalties work alongside penalty points
HMRC late payment penalties rules are separate from the points regime. There is no penalty if payment is up to 15 days late. In the first year of the new penalties, taxpayers have 30 days from the due date to pay in full or contact HMRC to set up a payment plan before penalties start. After the first year, that grace window reduces to 15 days.
For the 2026 to 2027 tax year, the charge is 3% of the tax owed at day 15 for payments 16 to 30 days late, unless it is the taxpayer’s first year. At 31 days or more, HMRC says the charge becomes 3% of the tax owed at day 15 and 3% at day 30, plus a 10% annualised charge on the outstanding amount from day 31.
That is why payment planning matters just as much as submission planning.
How to avoid HMRC penalty points through better record-keeping
The easiest way to avoid HMRC penalty points is to reduce deadline friction. In practice, that means:
- keep digital records current, not retrospective
- reconcile income and expenses monthly
- review each quarter before submission, not after
- separate filing dates from payment dates in your workflow
- act early if a payment problem is coming.

Quarterly updates and final declaration: Where mistakes are most likely
One detail many people tend to miss is that HMRC says there are no penalties for missing a quarterly update deadline in the 2026 to 2027 tax year. That does not remove the need to keep digital records or submit those updates before the tax return can be filed. It simply means the first year has a limited soft landing on quarterly update penalties.
The mistake risk therefore shifts to three areas:
- weak record quality across the year
- delays at final declaration stage
- assuming a missed filing is harmless because one quarterly penalty was waived.
What to do now if you want to stay compliant in 2026
The strongest response is operational, not theoretical.
- Confirm whether your qualifying income puts you into April 2026.
- Move record-keeping into compatible digital systems.
- Build a submission calendar that includes both filing and payment dates.
- Get quarterly review support in place before the first deadline cycle.
- Put a payment plan discussion on the table early if cash flow may be tight.
Prevent the first point and you reduce the bigger risk
The core issue in 2026 is whether your process is strong enough to stop one missed step becoming two penalties. Filing discipline and payment discipline now need to work together. For self-employed people and landlords moving into MTD for Income Tax, the safest approach is early setup, clean records, and regular review.
If your current system still depends on year-end catch-up, now is the point to change it. A cleaner process reduces the chance of penalty points, late payment charges, and avoidable disruption.
