End of tax year: know what to do

The tax year is from 1 April to 31 March. After the end of the tax year, we work out if you’ve paid the right amount of tax, if you have tax to pay, or if you're due a refund.

Avoid delays, update your details

Sometimes we need more information from you to work out your assessment, particularly if you get payments for Working for Families. You can avoid delays by checking your details are up to date in myIR.

Issues with logging in to myIR

We’ll be in touch in June

We start sending income tax assessments out in June — this is when you’ll find out if you have paid the right amount of tax or have a refund or bill. We'll also let you know if we need more information, so you don’t need to contact us before then.

If you receive Working for Families payments, we send most assessments out by 5 June, however, if we need more information it may take until 31 July. Again, there’s no need to contact us before then.
