Tax Facts - Director Identification Numbers

The director identification number (DIN) is a unique permanent identifier for each person who consents to being a director. DINs provide traceability of a director's relationships across companies and allow regulators and administrators to investigate a director's involvement in unlawful activity including illegal phoenix activity.

Subject to the transitional arrangements (see below) and exemptions, a director of a registered body corporate must apply for a DIN before becoming a director. Initially, the DIN will operate only in relation to appointed directors and acting alternate directors and not to de facto or shadow directors. The requirements apply to both Australian companies and registered foreign companies that are body corporates.

Applying for a DIN

Individuals requiring a DIN can apply online. An agent, or other third party, usually cannot apply for a DIN on behalf of a director. An applicant for a DIN will be required to complete a declaration confirming his/her identity and eligibility to obtain a DIN.

Transitional arrangements

Directors appointed on or before 31 October 2021, must have a DIN by 30 November 2022. Directors appointed between 1 November 2021 and 4 April 2022 must have a DIN within 28 days of appointment. Directors appointed on or after 5 April 2022 must have a DIN before appointment.
