We work out your income tax for you if we have all your income information for the tax year – 1 April to 31 March. This income tax assessment shows if you are due a refund, have a tax bill or have paid the right amount of tax.

Who gets an income tax assessment

We’ll send you an income tax assessment if your only income is salary, wages or investment income that’s already taxed, like bank deposits or savings interest.

This includes income from:

  • portfolio investment entities (PIEs) like KiwiSaver
  • NZ Superannuation
  • schedular payments for contractors
  • income-tested benefits like the Jobseeker or Sole Parent Support
  • interest or dividends
  • taxable Māori authority distributions
  • benefits under an employee share scheme (ESS) – where your employer offers you shares in the company as part of your pay.

We may ask you for more information before we confirm your assessment.
