penalty for late return

My personal tax account form tracker shows that my self-assessment tax return has been received on 19 Jan 2023, before the deadline 13 Feb 2023. But I still see a penalty for late file return. What should I do?

I've also submitted a Tax Return for 2021/22 on time (but by post - using a Cetrificate of Postage) and I've received a Late Return Penalty. I've found it impossible so far to contact HMRC and continue to get demands for payment. I'll post here if I find a solution.

Hi Kwan,

If the return was sent before the deadline there should not be a penalty.

Log into your account and access Self Assessment. Access your completed return and ensure that it says 100% complete and that it has been submitted to HMRC.

Thank you.
