Let’s get you ready for Making Tax Digital

Making Tax Digital will soon be mandatory for self-employed individuals and landlords. It will be staggered, and not everyone will need to enrol right away, but it is important to be prepared. There are three key upcoming dates after which people will be affected.
‍

April 2026: Self-employed individuals and landlords with total annual business or property income of more than £50k.

April 2027: Self-employed individuals and landlords with total annual business or property income of more than £30k.

April 2028: Self-employed individuals and landlords with total annual business or property income of more than £20k.

Even if you're not required to opt in yet, maintaining digital records early allows you to get comfortable with the software and processes at your own speed. This can help ease the transition and reduce the risk of errors later.

This is something our team will be happy to help you with!
