What Is Terminal Tax in New Zealand? Definition, Dates & IRD Compliance

Terminal tax in New Zealand is the final balance of income tax owed to Inland Revenue (IRD) after accounting for PAYE, provisional tax, and tax credits. It is paid once the annual income tax return has been assessed.

Terminal tax is usually due the year following income earned. Businesses and individuals who underpaid provisional tax during the year must pay terminal tax to settle their total liability.
