What is it?

Starting April 2026, mandated sole traders and landlords will be required to submit their tax returns through compatible software.

Instead of one annual return, they will also be asked to submit 4 quarterly updates.

Tax bills are calculated once a year, as normal.

When does it start?

Based on the 24-25 Self-Assessment:

Sales > £50,000  April 2026

Sales > £30,000  April 2027

Sales > £20,000  April 2028

What can I do NOW?

1. Separate your business and personal finances.
2. Decide which software you wish to use.
3. Familiarise yourself with the software.
4. Trial the process.
5. Consider onboarding a finance professional.
6. Consider costs vs time or error.
7. Complete tax year 25-26 ASAP to avoid an overlap.
