I use a agent to help with my self assessment

Is there a function for me to inhibit my agent to change my personal details and the ability to refund my tax.

tHi,

If you no longer want the agent to be able to change your personal details or claim a repayment your record will need to be updated to show that the agent no longer acts on your behalf.

You can contact HMRC to update at:

Income Tax: general enquiries

Thank you.
