EM0060 - Introduction: Self Assessment Tax System: HMRC Powers
Self Assessment gave taxpayers new and more clearly defined obligations. It correspondingly gives HMRC more clearly defined powers to ensure compliance with those obligations.
SA is a process now/check later regime. 鈥楶rocess now鈥� is underpinned by firmer procedural rules for filing of returns and payment of tax. 鈥楥heck later鈥� is supported by enquiry and information powers. Even if a repayment has been processed the repayment claim or the SA return may still be subject to later enquiry and amendment.
The SA rules apply to individuals, trusts and partnerships from 6 April 1996. CT Pay and File introduced 鈥榩rocess now鈥� rules for companies for accounting periods ending on or after 31 July 1993. CTSA rules apply to companies for accounting periods ending on or after 1 July 1999.
