Hi,
Ultimately, the responsibility for ensuring your returns are filed on time is yours.
The due date for your 22/23 return to be filed was the 31st of January 2024 - as late filing and payment penalties will now be accruing for this return, either file the return yourself or arrange to have it filed with another accountant as soon as possible.
While you are liable for any fines present on your record, if you believe these are the fault of the accountant you hired, you may consider approaching them to discuss who should pay.
You can also appeal the penalties, if you believe they are unfairly or incorrectly applied - just go to
Appeal a Self Assessment penalty for late filing or late payment
Thank you.
