What Is Making Tax Digital for Income Tax UK?
Making Tax Digital for Income Tax UK, often shortened to MTD for ITSA, is a government initiative from HMRC designed to move the tax system fully digital.
Instead of submitting one Self Assessment tax return per year, sole traders will:
-
Keep digital records
-
Use compatible accounting software
-
Submit quarterly updates to HMRC
-
Submit a final end of year declaration
The aim is to improve accuracy, reduce errors and help business owners understand their tax position throughout the year rather than in one annual rush.
Who Does Making Tax Digital for Income Tax UK Apply To?
Making Tax Digital for Income Tax UK will apply to:
From April 2026
Sole traders and landlords with income over £50,000.
From April 2027
Sole traders and landlords with income over £30,000.
Income is based on gross trading or property income, not profit.
If your income is below these thresholds, you will remain on Self Assessment for now. However, it is widely expected that thresholds may reduce over time.
That means preparing early is a smart move.
Does Making Tax Digital for Income Tax UK Replace Self Assessment?
Not immediately.
Making Tax Digital for Income Tax UK will work alongside Self Assessment initially.
You will still complete a final declaration at the end of the tax year, similar to a tax return. However, instead of one annual submission, you will also submit quarterly updates throughout the year.
Over time, the traditional once a year Self Assessment model is likely to be phased out for sole traders within scope.
What Will You Need To Do Under MTD for ITSA?
If you fall within Making Tax Digital for Income Tax UK, you will need to:
-
Use compatible accounting software
-
Keep digital records of income and expenses
-
Submit quarterly updates
-
Submit a final end of year statement
This means spreadsheets alone will no longer be enough unless they are digitally linked and compliant.
For many sole traders, this is the moment where bookkeeping becomes non negotiable.
Why This Change Matters for Sole Traders
For ambitious sole traders, especially business mums balancing work and family, this shift is significant.

-
Leaving bookkeeping until January

Guessing tax liabilities

Rushing to meet deadlines
You will need:

-
Quarterly visibility
-
Cash flow awareness
-
Forward planning

And visibility creates better decision making.
What If You’re Earning Over £50,000?
If your gross income is over £50,000, you are first in line.
That means:
-
April 2026 will arrive quickly
-
Software decisions need to be made
-
Bookkeeping processes need to be set up
-
Quarterly submissions need to feel manageable
Waiting until the last minute will create unnecessary stress.
Preparing early gives you control.

Check your gross income level
