What is a corporate tax return? 


A corporation tax return reports your company’s taxable profits to HMRC and determines the amount of corporation tax that is due. 

Preparing a corporate tax return involves more than applying a tax rate. It requires a sound understanding of your accounts, careful treatment of allowances and reliefs, and accurate submission within strict deadlines.

We manage the full process, including: 

  • Preparation and submission of your returns and accounts in HMRC’s required iXBRL format.
  • Calculation of your corporation tax liability. 
  • A review of your accounts from a tax perspective.
  • Identification of available reliefs and allowances. 
  • Capital allowances claims.
  • Liaison with HMRC where required.
