What happens if my accounting period exceeds 12 months?

If your accounting period exceeds 12 months, Zoho Books automatically divides it into two separate Corporation Tax returns, as required by HMRC.

For example, if an accounting period lasts 16 months, from 1 January 2025 to 30 April 2026, two Corporation Tax returns will be created. The first return covers 1 January 2025 to 31 December 2025 (12 months), and the second return covers 1 January 2026 to 30 April 2026 (4 months).

All income, expenses, and profits will be apportioned proportionally between the two periods. You must file both returns by their respective deadlines.
