The basics

What is Making Tax Digital for Income Tax?

Making Tax Digital for Income Tax Self Assessment (MTD Income Tax) is an HMRC initiative that requires self-employed people and landlords to keep digital records and send regular updates to HMRC throughout the year — instead of one annual Self Assessment return.

Rather than reporting all your income and expenses once a year, you will submit a summary to HMRC every three months, with a final declaration at the end of the tax year.

The aim is to make tax reporting more accurate, reduce errors, and give self-employed people a clearer picture of their tax liability in real time.

Old way
1 Self Assessment return per year
Paper records or spreadsheets allowed
Tax surprise at year end
January deadline rush
MTD way
4 quarterly updates + final declaration
HMRC-recognised software required
Real-time tax estimates year-round
Spread the workload across the year
Quarterly updates do not replace Self Assessment — they work alongside the final declaration.
How it works

Four updates a year

Under MTD, you submit a summary of your income and expenses to HMRC four times a year — once per quarter — then make a final declaration at the end of the tax year.

What you submit each quarter

A summary of your total income and total allowable expenses for that quarter. You do not need to submit every individual transaction — just the totals.

What you keep as records

Every individual income and expense transaction must be recorded digitally in HMRC-compliant software. These are your underlying records — they must be accurate and kept for at least 5 years.

The final declaration

At the end of the tax year you confirm your total income, claim any additional reliefs, and make your final declaration to HMRC. This is due by 31 January — the same deadline as before.

Does MTD apply to me?
Self-employed income Included
Trading income from your business — invoices, cash sales, freelance fees
Rental income Included
UK property income from letting property counts toward the threshold
Employment income (PAYE) & other income Not included
Salary from employments or other sources does not count toward the MTD threshold
The threshold is based on gross income — before expenses. Check your 2024/25 Self Assessment to see if you are affected.
Who it affects

Are you affected by MTD?

MTD for Income Tax applies to self-employed sole traders and landlords whose combined gross income from self-employment and property exceeds the threshold.

It does not matter whether you run one business or several — all your self-employment and rental income is added together to determine whether you are above the threshold.

If you are above the threshold and not already using HMRC-recognised software, now is the time to start. Records built up over a full year in the right format will make your first quarterly submission straightforward.

Freelancers, consultants, and contractors
Tradespeople — builders, plumbers, electricians
Landlords with rental income above the threshold
Anyone running a sole trade alongside PAYE employment
Penalties

What happens if you miss a quarterly deadline?

HMRC is introducing a new points-based penalty system for MTD. Rather than an immediate fine for one late submission, you accumulate penalty points over time — but the penalties can still add up quickly.

The best approach is consistent, timely submissions throughout the year — which is exactly what StrideBooks is designed to support.
