@HMRCcustomers Yes i tried to amend the 2024-2025 online and it said this "As the HMRC service was not used to file a tax return for this year, you can't use the service to amend that return. Self Assessment Helpline for further assistance."

@SaimaHaideqf Hi Saima, Have you tried signing back in, since deregistering only sends a UTR dormant, so you can still access it. Steve

@HMRCcustomers We deregistered for self assessment tax for year 2024-2025 however changed out mind and I filled in the registration form on 16th December. I have not received any activation code yet?

@HMRCcustomers But i need to submit return by 31st January or they will give me a fine?

@SaimaHaideqf It's taking up to 6 weeks for that to process. Steve

@HMRCcustomers i need to reactivate my account and file 2024-2025 tax return before 31st January 2026z

@HMRCcustomers I filled this form in on 16th December, but I have not heard anything back yet.

@SaimaHaideqf Hi Saima, You'll have to reregister gov.uk/guidance/regis… Steve

@HMRCcustomers I have deregistered for self assessment as I thought I would pay the high rate child benefit tax through PAYE. But i have changed my mind and want to oay it through self assessment. Please can you tell me how I can reactivate my account?
