SolvedCTM35125 | Income Tax: collection of tax on annual payments: set off of tax suffered by deduction
From HM Revenue & Customs · Company Taxation Manual
Income Tax deducted from any payment received by a company in an accounting period can be set-off against any IT it is liable to pay in respect of the S946 payments made by it in that period.
The claim for set-off is included in a return made under CHAPTER15.
The company will also get a repayment of IT paid in an earlier return period if it has had tax deducted from a payment received later in the same accounting period.
Where IT suffered by deduction is used for the purposes of a claim under CHAPTER15 the same tax is not to be set off against the company's CT liability under CTA10/S967 and S968, CTM35220.
