Amendment of Company Tax Returns

April 1st 2010

The current process for amending a Company Tax Return at the conclusion of an enquiry gives two consecutive windows of 30 days after the issue of the closure notice during which the return can be amended, firstly by the company and then by HMRC.

The company has a right of appeal against an HMRC amendment.Paragraph 34 of Schedule 18 FA1998 has been amended to remove those two 30 day windows and require the closure notice to amend the return to agree with HMRC’s conclusions. A separate provision allows HMRC to make any consequential amendments to other returns made by the company that are affected by the conclusions.

The company’s right of appeal against an HMRC amendment is preserved. The company has 30 days after being notified of the amendment to appeal against it.

The CTSA closure process will, from 1 April 2010, more closely align with the current Self Assessment closure process.
