Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if he will make an estimate of the cost to the public purse of HMRC sending (a) paper self-assessment tax returns to people who complete their tax returns online for the 2023-24 financial year and (b) correction letters to those people.

HMRC are aware that some customers who normally file their Self Assessment (SA) tax returns online have received a paper SA. These were sent in error, and customers who were expecting to file online should continue to do so. HMRC have written to everyone affected to apologise for the confusion and to reassure them that they do not need to take any action other than to file their return, which they can still do online, by the 31^st January 2025.
