Important HMRC update for businesses and professionals dealing with tax matters
HMRC is introducing a new digital registration system for tax advisers from 18 May 2026.
This will apply more widely than many expect, not just to traditional tax firms.
If you are paid to interact with HMRC on behalf of clients, you may now fall within scope of the new “tax adviser” registration rules. This can include submitting returns, making claims, or corresponding with HMRC on a client’s behalf.
Why this matters:
After a short transition period, unregistered advisers may be unable to deal with HMRC for clients.
What you should do now:
Businesses should review whether any services involve HMRC interaction and confirm whether registration will be required under the new regime.
If you’re unsure whether this affects you, please get in touch.
