Director Identification Number Regime


The Director Identification Number (DIN) regime has been passed by parliament and is now law. All directors of companies registered under the Corporations Act 2001 will now need to have one unique identifier.

The DIN is a measure that limits the opportunities for a company and its directors to engage in illegal phoenixing activities. This new measure requires all directors to confirm their identity before receiving a DIN, and there are civil and criminal penalties for system misuse. This includes intentionally applying for more than one DIN.

From 1 November 2021, this register will be open for applications at Australian Business Registry Services (

Transitional period

From 1 November 2021, a 12 month transitional period will apply for current directors of Australian companies.

It was 6 years ago when I transferred my business and personal accounts and many of our family accounts to Loewy Consulting Partners where Mr. Mark Lindsay himself oversaw our work and took a close professional and personal interest in it all.

Both myself and the family are extremely satisfied with the accounting expertise and the general overall advice.
