What Is Corporation Tax?

Corporation Tax is a tax your company pays on its profits. You must calculate, report, and pay this tax to HMRC annually — typically alongside your year-end accounts.

As of 2025, Corporation Tax rates vary depending on your profit level, so accurate calculations are essential to avoid overpaying or being penalised.
