I stopped my self employment on 20/01/2023 and I have been working for an employer since 23/01/2023. I used an online form to notify HMRC of this and I also included this information on my final tax return submitted on 09/04/2023 but I continued to receive regular emails asking me to complete a self assessment tax return for 2023/24. When I contacted HMRC several weeks ago via live chat the agent found the online form that I had submitted and informed me that I would be removed from Self Assessment, however I am still receiving emails asking me to complete a tax return for 2023/24 and, having logged into my tax account, it appears that I am still registered for Self Assessment. I have again today tried to resolve this via live chat but I get a message that agents are unavailable. Could someone please advise what might be the best course of action for me to be removed from Self Assessment.
