Does your company have a 31 December 2025 year-end?

Two important deadlines are almost back-to-back:

30 September 2026 – annual accounts due to Companies House
1 October 2026 – Corporation Tax payment due to HMRC

Your Company Tax Return, including the CT600, is not due until 31 December 2026.

The important point is that the Corporation Tax payment deadline normally comes before the return filing deadline. This means your accounts and tax calculation should be prepared in time to establish how much Corporation Tax is payable.

If your accounts are not already underway, act now. Send us your year-end records as soon as possible:

These are the standard deadlines for most established private companies. Different rules may apply to first accounts, changed accounting periods or companies paying Corporation Tax by instalments.

Director pay is not a “set it and forget it” decision.

The salary-and-dividend mix that worked in 2024 may no longer be the most tax-efficient for 2026/27. Employer National Insurance is now 15% above the £5,000 Secondary Threshold, while the Dividend Allowance remains just £500.

These figures can materially change the most effective way for owner-managed companies to extract profits. The right approach will depend on your company, income and eligibility for reliefs.

If you have not reviewed your director pay recently, now is the time — ideally before declaring your next dividend.
