Income tax Dates
Check if you need to file an IR3
Before you start, check if you need to file a return.
If you do not need to file, your income tax will be automatically assessed instead.
Gather your information
You will need:
- your IRD number
- details of your income for the tax year
- details of any expenses you want to claim.
If you received taxed income like salary or wages we'll put the details in your individual tax return. You need to check this information and change it if it's wrong.
Depending on where your income came from, you may also need to fill out some extra forms:
- a Financial statements summary - IR10 for untaxed income from your business
- a Rental income schedule - IR3R for rental income
- a Property sale information form - IR833 for any income from a taxable property sale
- an Adjust your income form - IR215 for any adjustments to your income if you received Working for Families payments or have a student loan.
If you file your return online, you can fill out these forms as part of the return.
