how to track my UTR number apply status?

Hi HMRC, I've registered a UTR number online for my self-assessment since last weekend 13 Dec 2024 . I didn't receive any notification from email or phone call or SMS . May I track the application status? As I am late to apply. I'm afraid that there is a penalty for my late self-assessment submission. And this is my first year in UK to submit self-assessment. Thanks

Hi,
You can find out when you should receive your UTR here:
Check when you can expect a reply from HMRC
Thank you.

Thank you for your help. However, if I still cannot receive the UTR number until the expected date, what can I do?

Hi,
You will need to await the UTR as you cannot file a return without one. The "Check when you can expect to receive a UTR" gives a date of 20/01/25 for receipt if you applied online on 13/12/24.
If however you do not receive the UTR and file late and receive a penalty, you can appeal against any penalty that may have been charged. Please find guidance at:
Appeal a Self Assessment penalty for late filing or late payment.
Thank you.
