Registrations for business

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.

Work out which registrations you need

Some registrations are compulsory, while others are optional. It's best to get an Australian business number (ABN) and secure online identification to deal with us online. You may also need to register for GST and other tax obligations.
