How does Making Tax Digital work in practice?
Making Tax Digital (MTD) changes how income is reported to HMRC. Instead of submitting one Self Assessment tax return each year, reporting becomes ongoing and digital.
If you fall within MTD for Income Tax, you will be required to keep digital records and submit updates to HMRC throughout the year.
The aim is to improve accuracy and reduce errors, but it does change the reporting process.
Step 1: Keep digital records
Under MTD, you must maintain digital records of your income and expenses.
This means:
- Recording income and allowable expenses digitally
- Using MTD compatible software
- Keeping records up to date
You can use accounting software or a spreadsheet that links to compatible submission software.
Paper records alone will not meet MTD requirements.
Step 2: Submit quarterly updates
Instead of one annual submission, you will send summary updates to HMRC every three months.
These updates will include:
- Total income for the period
- Total expenses for the period
They are not full tax returns. They are summary figures based on your digital records.
There will usually be four quarterly submissions each tax year.
Step 3: Submit a final declaration
At the end of the tax year, you will still need to confirm your overall tax position.
This is known as the final declaration.
It replaces the current Self Assessment return and includes:
- Any adjustments
- Other sources of income
- Claims and reliefs
- Confirmation of your final tax liability
So although reporting becomes more frequent, there is still a year end process.
Will I pay tax quarterly?
In most cases, no.
MTD changes how income is reported, not when tax is paid.
Payment deadlines are expected to remain aligned with the current Self Assessment system unless HMRC announces future changes.
What does this mean day to day?
In practical terms, you will need to:
- Keep your records up to date during the year
- Ensure figures are ready each quarter
- Submit updates on time
- Complete the final declaration at year end
The key difference is that reporting becomes ongoing rather than once a year.
What happens if I miss a deadline?
HMRC will apply a points based penalty system for late submissions.
Each missed quarterly update adds a penalty point. Once you reach a certain number of points, a financial penalty applies.
This makes staying organised and meeting deadlines more important than before.
Final thoughts
Making Tax Digital introduces a more regular reporting cycle, but the underlying tax rules remain the same.
You will keep digital records, submit quarterly updates, and complete a final declaration each year.
Understanding how the system works allows you to prepare early and decide how much support you want.
TaxStore provides clear MTD options for individuals who want digital compliance handled properly and on time.
