The Act Part 6 – Tax Returns, Enquiries and Assessments Completion of enquiry Section 93 – Completion of enquiry
132.This section provides for completion of an enquiry. An enquiry is completed when a designated officer notifies the relevant person (defined in section 85(2)(a)) that the enquiry is complete (a “closure notice”). The closure notice must state the conclusions reached in the enquiry and must be given no later than three years after the relevant date (defined in section 85(3)). If no closure notice is given, an enquiry is also treated as complete three years after the relevant date. A designated officer can make an amendment of a return and give it to the relevant person with the closure notice. The taxpayer must pay any amount, or additional amount, of tax chargeable as a result of an amendment under this section within 30 days of the closure notice being given. Where a designated officer issues notice of an amendment under this section, section 83 no longer applies and the taxpayer cannot therefore submit any further amendment of their own.
