Australian Business Register (ABR)

ABN registration for government

The Australian Business Register (ABR)'s Application for ABN registration for government organisations should be used by government organisations to apply for an ABN. Online registration is not available for government organisations.

Registration

If you’re in business you should get an Australian business number (ABN). You may also need to register for certain tax obligations and entitlements. We use registration to manage the tax and superannuation systems fairly for all businesses and their employees.

Update your details

You're required by law to tell us within 28 days when your business details change, such as address or associates.
