Audit timing requirement: deduction for Site Restoration Fund allowed only if accounts audited and report furnished by the specified date. Amendment makes the Site Restoration Fund deduction conditional on the business accounts being audited by a defined accountant and the audit report being furnished by the specified date referred to in the audit provisions (one month prior to the due date for filing the return); the deduction under subsection (1) is therefore admissible only if both audit and submission of the audit report occur before that specified date, with effect from the financial year commencing 1 April, 2020.
