Part 7Interest
General provisions
120FInterest priority and rights of Commissioner
The Commissioner must apply amounts paid on account of a taxpayer’s liability for unpaid tax and interest for a return period using the following pattern and order:
- apply against interest on the amount of unpaid tax that arises first for the return period (the earliest unpaid tax) until that interest is paid; then
- apply against the earliest unpaid tax, until that tax is paid; then
- apply against the interest on the amount of unpaid tax that arises next for the return period (the next unpaid tax) until that interest is paid; then
- apply against the next unpaid tax, until that tax is paid; then
- apply to each later arising interest and unpaid tax amount, interest first, in time order that relevant unpaid tax amount arises for the return period, until they are paid.
The Commissioner may apply interest payable by the Commissioner to a taxpayer towards the payment of the taxpayer's unpaid tax on or after the date the taxpayer furnishes their return of income.
The Commissioner may apply interest under subsection (2) only if the Commissioner is not prevented, by a tax law, from applying the relevant overpaid tax towards the payment of the tax.
If, for a period,—
- a taxpayer is liable to pay the Commissioner interest on unpaid tax; and
- the Commissioner is liable to pay the taxpayer interest on overpaid tax,—
- assess the taxpayer for the net amount of interest payable by the taxpayer for the period; or
- pay the taxpayer the net amount of interest payable by the Commissioner for the period.
In this section, the expressions unpaid tax and overpaid tax include—
- any tax which has not been paid or which has been overpaid; and
- any civil penalty imposed in respect of that tax which has not been paid or which has been overpaid,—
