Plenty of landlords and sole traders hear "Making Tax Digital" and panic that their tax is going up. It isn't. MTD for Income Tax changes the process of reporting, not the tax itself. Here's the side-by-side.
The old way vs the new way
| Self Assessment (until now) | MTD for Income Tax (from your start date) |
|---|---|
| One annual tax return | Four quarterly updates + a final declaration |
| Records can be paper or spreadsheets | Digital records in compatible software |
| One deadline (31 January) | Five deadlines across the year |
| File once, often in the January rush | Report as you go, quarter by quarter |
What stays exactly the same
- Your tax bill is calculated the same way — same allowances, same rates, same reliefs.
- Payment dates are unchanged — tax is still due 31 January (with payments on account on 31 January and 31 July where they apply).
- What's taxable — your income and allowable expenses don't change.
What's genuinely new
- Frequency. You report figures four times a year, then confirm everything in a final declaration.
- Digital record-keeping. Records must be kept in MTD-compatible software, with a digital link through to your submissions.
- Points-based penalties. Miss a quarterly deadline and you collect a penalty point; enough points trigger a fine.
The mindset shift: instead of one big annual scramble, MTD spreads the admin across the year. Done well, that's actually less stressful — your numbers are always up to date. Done badly, it's four chances to miss a deadline instead of one. That's the difference a system (or a service) makes.
When it starts for you
