CTM20200 | ACT: set-off against CT on profits: withdrawal or variation of claims
From HM Revenue & Customs · Company Taxation Manual
There was no provision in the legislation for withdrawing or varying claims after they had been made, but any request for a ICTA88/S239 (3) claim to be withdrawn or varied was dealt with as follows.
If the claim had been settled, a request for a withdrawal or reduction was refused. The company could however make new or supplementary claims within the two-year time limit.
If the claim had not been settled, a request for a claim to be withdrawn, or for a new claim made within the time limit to be admitted, could be accepted.
A claim was settled when:
a written decision was given on the claim and the company did not appeal against it, or
if the decision was not conveyed in writing, when an assessment in which the ACT was allowed became final and conclusive.
When a written decision was given, the claim was then settled even if the ACT had not then been set-off for the earlier period.
