Update your ABN details

We are updating our systems so now is the time to update your Australian business number (ABN) details to ensure you are aware of any changes that occur in the future.

By keeping your details current, you'll be able to:

  • keep up to date with information from us and other government agencies
  • help us identify businesses like yours to provide assistance and support during times of disaster
  • help other businesses confirm your business identity so they know your business is genuine and their dealings with you are legitimate.

If you're no longer in business you should cancel your ABN. This helps us keep the register current.

To update or cancel your ABN details, see Update your ABN details. All changes made to your ABN online will generally take effect immediately.
