Each year HMRC issues a notice to file a corporation tax return which must be submitted within 12 months of the end of the accounting period. We can prepare your return and advise on tax.

Filing your company tax return - This has to be done online and the accounts and computations are sent at the same time. A penalty is due if it is filed late. The return can be amended by the company within 12 months of the statutory filing date.

HMRC check returns and can enquire into the completeness and accuracy of a return.


  • HMRC have 12 months from the filing date the in which to commence an enquiry
  • If no enquiry is started the company's return becomes final - subject to a 'discovery'
  • HMRC will give the company formal notice when an enquiry commences
  • HMRC give notice of the completion of an enquiry stating their conclusions
  • A company may ask the Commissioners to direct HMRC to close an enquiry if there are no reasonable grounds for continuing it

Discovery assessments - HMRC have the power to make a discovery assessment if information comes to light after the end of the enquiry period ie. as a result of fraudulent disclosure.

Corporation tax  - is payable nine months after the end of the accounting period.
