Question to the HM Treasury:

To ask His Majesty's Government, following reports of a 10 per cent increase in UK taxpayers missing the self-assessment filing deadline, what steps they are taking to identify the factors that may have contributed to this increase.

The number and proportion of people who haven’t filed on time this year is similar to last year. This year, 11.5m customers filed their returns by close on 31st January compared to 11.4 million last year.

1.1 million customers did not file their return by the filing date and we are currently evaluating why this might be the case, although the number is similar to last year. We will be working to improve our understanding of customers who did not file on time before considering if there are opportunities to influence that group in future campaigns.
