Taxation Administration Act 2001

Tax payable under a tax law must be paid—

for a return self assessment—on the date the return for the self assessment is required to be lodged; or

for a standard self assessment—by the date that is 14 days after the date the transaction statement for the self assessment is lodged; or

for a default assessment made because of a failure to make a self assessment—on the date the assessment notice for the default assessment is given to the taxpayer; or

for an amount of tax, payable under a royalty law, for which the royalty law provides a time for payment—by that time; or

otherwise—by the date stated in the assessment notice as the date by which the tax must be paid.

For subsection (1)(e), the stated date must be at least 30 days after the assessment notice for the tax is given to the taxpayer.

For a return self-assessment, assessed interest is payable on the day the assessment is made.
