Making Tax Digital (MTD) for Income Tax is approaching and while many businesses are focusing on the new reporting requirements, it’s equally important to understand what happens if those requirements aren’t met.
Like most HMRC obligations, MTD comes with a system of penalties for missed submissions or late updates. The good news is that once you understand how the system works, avoiding these penalties becomes much easier.
Below, we explain the key Making Tax Digital requirements, the reporting deadlines you’ll need to meet and the penalties that can apply if they’re missed.
What Are the Making Tax Digital Requirements?
Making Tax Digital for Income Tax requires individuals with qualifying income to keep digital records and submit updates to HMRC more regularly.
If you are affected, you will need to:
- Keep digital records of income and expenses
- Submit quarterly updates to HMRC
- Submit a Final Declaration after the end of the tax year
These updates replace the traditional once-a-year Self Assessment return for those within the scheme.
The goal is to give HMRC (and you) a more accurate, real-time picture of taxable income.
When Does Making Tax Digital Start?
The rollout will happen in stages.
From April 2026
- Sole traders and landlords with income over £50,000
From April 2027
- Sole traders and landlords with income over £30,000
From April 2028
- Sole traders and landlords with income over £20,000
Your income (pre expenses) is assessed based on your Self Assessment return from the 2024/25 tax year.
If you fall within these thresholds, you will be required to follow the MTD rules.
The Making Tax Digital Deadline Structure
Under MTD, reporting happens four times per year, rather than once.
The quarterly deadlines for 2026/27 fall on:
- 7 August
- 7 November
- 7 February
- 7 May
You will also submit a Final Declaration by 31 January, similar to the current Self Assessment deadline.
Missing any of these deadlines may result in penalties.
How the Making Tax Digital Penalty System Works
HMRC is introducing a points-based penalty system. Each time a submission deadline is missed, a penalty point is added to your account. Once you reach a certain number of points, you receive a financial penalty.
For quarterly submissions, the threshold is expected to be four points. Once the threshold is reached:
- You receive a £200 penalty
- Additional missed deadlines trigger further £200 penalties
Points remain on your record until you have demonstrated compliance for a set period.
There are no penalties for missing a quarterly update deadline for the 2026 to 2027 tax year with the system coming into effect starting with the 2027 to 2028 tax year.
Late Payment Penalties
Separate penalties apply if tax is paid late.
These can include:
- A penalty after 15 days
- Additional penalties after 30 days
- Ongoing interest charges on overdue amounts
This means that missing deadlines can quickly become expensive if issues are not addressed.
Why Many Businesses Are Preparing Early
One of the biggest challenges with MTD isn’t the reporting itself, it’s adapting to the more frequent reporting schedule.
Moving from one annual return to four updates per year requires:
- Consistent record keeping
- Digital software
- Regular financial organisation
Businesses who prepare early often find the transition much smoother.
