Income Tax Return
Taxable income is governed by Income Tax Act 2007 and is administered by Inland Revenue department. Income tax is filed once in a year, for individuals and most businesses the accounting year begins on 1 April and ends the following 31 March, but businesses can choose a different balance date. Income tax returns are due on 7 July each year, unless you have a tax agent, in which case you get extension of time.
All income is taxed in New Zealand, like many other countries there is no tax-free threshold. But individuals can get rebates and credits depending upon their personal situation.
New Zealand Tax residents are also required to declare their worldwide income.

Income from all sources, taxed and untaxed is added up and total taxable income is considered to calculate income tax. Residual Income Tax (RIT) is calculated after deducting any PAYE and other tax credits you may be entitled to, (except for Working for Families Tax Credits).
For businesses and organisations
After the balance date, your accountant will prepare a set of annual financial statement. There is different rule that govern financial reporting requirement of small and large businesses.
Income tax return is prepared on the basis of outcome of the financial reports. For small businesses financial statement summary is filed with IRD along with the income tax return.
Any provisional tax already paid and tax credits are adjusted at this stage and final income tax (RIT) payable amount is calculated.
