Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how much was paid in fines by people who submitted tax returns after the deadline of 31 January in each year since 2018.

Analysis of self-assessment penalty data is complex and HMRC are currently investigating whether it is possible to provide the requested figures. I shall write to the Honourable Member shortly and place a copy of the letter in the Library of both Houses.
