What Is Income Tax in New Zealand? Definition, Rates & Filing Rules

Income tax in New Zealand is a compulsory tax paid on income earned by individuals, companies, and trusts. The Inland Revenue (IRD) sets progressive tax rates for individuals, while companies pay a flat rate of 28%.

Taxpayers must file income tax returns each year unless exempt, and businesses may also pay provisional tax during the year. Accurate reporting avoids penalties and supports compliance.
