How to apply

There are two stages to the application process:

  • Verifying the director’s identify

  • Linking the director to the business’s ABN

In most cases directors will apply online through the ABSR using myGovID. (myGovID is an identification verification app)

For clients who cannot obtain a myGovID then the best way to apply depends on their situation:

  • Individual has a TFN - If the individual has an Australian TFN then they can apply by phone.

  • Individual does not have a TFN. The individual will need to apply with a paper form (available to download from November 2021) and will need to provide certified copies of documents to verify their identity.

The Directors details will need to match the information held by ASIC.

If need more information, please refer to

Individuals will not need a director ID if they are running a business as a sole trader or partnership.

Note: Tax Agents or BAS agents cannot apply for DIN on behalf of there clients, individuals concerned need to apply it themselves.
