# What is Corporation Tax?

Checked 2026-10-01. By the RewardsPilot team.

Corporation Tax is the tax a UK limited company, foreign company with a UK branch, or unincorporated association pays to HM Revenue and Customs on its profits for an accounting period. There is no bill: the company works out what it owes in a Company Tax Return and pays it, usually 9 months and 1 day after the period ends.

## What to know

- The amount depends on the profit made; allowances and reliefs may reduce it.
- The Company Tax Return must be filed even if the company made a loss or has nothing to pay, and late filing carries penalties.
- Companies with taxable profits over £1.5 million pay in instalments.
- The payment reference is 17 characters and changes with every accounting period.
