Completing your TFN declaration form online

How to complete your Tax file number (TFN) declaration form online.

Last updated 23 March 2025

Work out the type of electronic form to use and how to complete the form online.

Your payer may have their own electronic employment form. Check with them before completing the online form in ATO online services.

If your payer:

  • has their own electronic form, complete their form
  • doesn’t have their own electronic form, complete the ATO online form.

You can't use the ATO online form if:

  • you don’t have a TFN – complete a paper TFN declaration form (NAT 3092)
  • you're exempt from quoting your TFN – complete a paper TFN declaration form (NAT 3092)
  • you're entitled to the seniors and pensioners tax offset (SAPTO) and under 65.5 years old – complete a paper Withholding declaration form (NAT 3093).

To access the form in ATO online services, you need to link your myGov account to the Australian Taxation Office (ATO).

Sign in to myGovExternal Link and go to your linked services, then select:

  • Australian Taxation Office
  • Employment from the menu
  • New employment to complete your Tax file number declaration.

The online forms can be used for employment and non-employment related payments. This includes payments from a superannuation income stream or compensation payments.

For more information on completing the form online, see Access and complete employment forms in ATO online.
