Overview of DINs

New regulations require that all existing and new Directors acquire a unique Director Identification Number (DIN). The Australian Taxation Office (ATO) is responsible for administering the DIN regime. Your DIN is a unique identifier, much like your Tax File Number, that you will only be required to register for once. Penalties will apply for non-compliance with the DIN regime.

Who Needs to Register for a DIN?

Every existing or new director of a company listed with ASIC is required to register for a DIN. This includes:

  • Public companies

  • Private companies

  • Australian and Torres Strait Islander (ATSI) corporations

  • Registered foreign companies

  • Some incorporated associations

  • Some charities

Directors must register for their DIN personally and they cannot ask another person or even a Tax Agent to do it on their behalf.

Who Does Not Need to Register for a DIN?

Registration is not required for:

  • A company secretary (provided they are not also a director)

  • A person acting as an external administrator of a company (Registered ASIC Agent)

  • An individual or entity running a business as a sole-trader, partnership, trust, etc.

Deadlines for Obtaining a DIN

From 1 November 20201, directors will be able to register for a DIN. At TaxDigital, we highly recommend applying for the DIN as soon as practical. However, the deadlines for obtaining a DIN are outlined below:

How to Register for a DIN?

The first step is to register for a MyGovID account. (Note that it is different from the MyGov account.) You can find more information about a MyGovID account here.


After obtaining a MyGovID account, you can apply for a DIN on the Australian Business Registry Services (ABRS) website.

Registering for a MyGovID

  • Download the MyGovID app on your phone and register using your email address.
  • Verify your email with the passcode sent to your email address.
  • Verify your identity within the MyGovID app (to a "standard" identity strength).

Registering for a DIN

  • Once you have obtained "standard" strength in your MyGovID app, go to the ABRS website and complete the DIN application.
  • Use your email to log in to the website, and a security verification code will be sent to your MyGovID app.
  • Follow the prompts on the ABRS website to complete your application.

What do you do with a DIN?

Firstly, keep a record of your DIN in a safe place. We have not yet dealt with a lost DIN, but we suspect the process will be similar to a lost TFN (i.e., impossible).

Secondly, after you receive your DIN, it is essential to:

  • Provide the DIN to your accountant; and

  • Provide it to the company(s) of which you are currently a director; and

  • Provide it to any other companies you become a director of in the future; and

  • Keep your personal details up to date on the ABRS website and the MyGovID app.
