Commonwealth Consolidated Acts Commonwealth Consolidated Acts(1) Interest is payable by the Commissioner to a person in respect of an amount of grant or benefit that becomes payable to the person if:
(a) the amount relates to a grant or benefit for a claim period; and
(b) the amount is payable as a result of a decision to which this section applies (the review decision ).
(2) The interest is to be calculated for the period (the interest period ):
(a) starting on the day on which the original assessment in relation to the grant or benefit was made; and
(b) ending on the day on which the amount is paid or applied by the Commissioner.
(3) The following method statement shows how to work out the interest (which is calculated on a daily basis):
Calculating the interest payable
Step 1. Work out the amount that is determined by the review decision to be the amount of the grant or benefit payable in relation to the claim period.
Step 2. For each day in the interest period, work out the amount of the grant or benefit that had been paid or applied by the Commissioner on or before that day (reduced by any amounts repaid before that day by the person).
Step 3. For each day in the interest period, subtract the amount worked out in step 2 from the amount worked out in step 1. If the result is negative, it is taken to be nil.
Step 4. For each day in the interest period, multiply the amount worked out in step 3 by the base interest rate for the day (expressed as a daily rate).
Step 5. Add all of the amounts worked out under step 4.
(4) In this section:
"base interest rate" for a day has the same meaning as in section 8AAD of the Taxation Administration Act 1953 .
"decision to which this section applies" means:
(a) a decision under Part IVC of the Taxation Administration Act 1953 upon an objection relating to a grant or benefit; or
(b) a decision of the Administrative Review Tribunal in relation to an objection mentioned in paragraph (a); or
(c) a decision of a court in relation to:
(i) an objection mentioned in paragraph (a); or
(ii) a decision of the kind mentioned in paragraph (b).
