TFN eligibility questionnaire

Four yes/no questions tell you whether to apply for a TFN or find the one you already have. This is a preliminary questionnaire — we never ask you to enter your TFN, and only the ATO issues them.

Official site: ATO — Tax file number ↗

Type: preliminary eligibility questionnaire. No TFN is requested or stored.

  1. 1. Have you ever been issued a TFN before?

    You only ever get one TFN. If you had one, you need to find it, not apply again.

  2. 2. Are you an Australian resident for tax purposes, or a citizen/permanent resident?

  3. 3. Do you hold a visa that allows you to work or study in Australia?

  4. 4. Are you currently in Australia?

Answer every question to see the result.
