Five days to go, and this deadline falls on a Saturday.
31 October is the deadline for:
→ Paper Self Assessment tax returns for the 2025/26 tax year
→ Annual accounts filed with Companies House for limited companies with a 31 January 2026 year-end (due nine months after the financial year ends)
Miss a deadline and you could face a penalty. For late company accounts, penalties start at £150, with no warning letter required first.
