Taxation Administration Act 1953

The Commissioner may, having regard to the circumstances of your particular case, permit you to pay an amount of a *tax‑related liability by instalments under an *arrangement between you and the Commissioner (whether or not the liability has already arisen).

The *arrangement does not vary the time at which the amount is due and payable.

Despite an arrangement under this section, any general interest charge or other relevant penalty, if applicable for any unpaid amount of the liability, begins to accrue when the liability is due and payable under the relevant taxation law, or at that time as varied under section 255‑10 or 255‑20.
