WHAT IS CORPORATE TAX AND WHY DOES IT MATTER?

Corporate tax is a tax on the profits of limited companies and certain other organisations, including clubs and societies. Whether you're a director of a growing SME, a family-run firm, or a complex group, understanding and managing corporate tax is vital to your bottom line.

From April 2023, the main corporate tax rate is 25%, with a small profits rate of 19% applying to companies with profits under £50,000.

The tax landscape is changing and HMRC is placing more scrutiny on filings than ever before. Mistakes or missed opportunities can be costly but with the right advice, they can also be avoided.
