Advance tax instalment schedule: staged payments and a single-instalment rule for presumptive taxpayers streamline compliance and revenue flow.
Clause 408 requires assessees to pay advance tax in staged instalments during the tax year, with progressive minimum thresholds and specified due dates, and treats amounts paid on or before the last day of the tax year as advance tax. It provides a single-instalment exception for presumptive taxpayers and cross-references the statutory computation provision for determining current income, while updating terminology and certain cross-references that will require harmonisation with other provisions.
