Changes to the myIR login screen are coming You will not be able to use myIR between 1pm Saturday 8 October and 8am Monday 10 October. This is so we can update our external authentication system. From Monday 10 October the myIR login page will have a new look and feel, but the login process will not change.

Keeping your phone number and email address updated helps you manage your tax.

You can update your details anytime in myIR.

In myIR, select 'Manage my profile'

Go to the 'Profile' tab

From here you can select either:

  • 'Update email address'
