There are just two days to the 31 October 2024 self-assessment paper filing deadline for 2023/24 in order to avoid penalties. Readers are reminded that if an online self-assessment return cannot be filed by virtue of one of the online filing exclusions or special cases (search GOV.UK for details as these regularly change) meaning the return must be filed on paper instead, then in those cases, the 2023/24 paper filing deadline is extended to 31 January 2025. A reasonable excuse claim should accompany such returns.
