Business addresses

Sometimes called your primary address. This is the main place where you run your business.

The location of your principal place of business determines which state or territory tax rules you need to follow.

It must be a street address in Australia, not a post office box.

It can be the same as your principal place of business but doesn’t need to be. Some companies use the address of their accountants or lawyers.

The Australian Securities and Investment Commission (ASIC) publishes your registered office address in its company register.

Sometimes called your contact address or service of documents address. This is the address you use for mail you can’t receive online.

For example, some:

• government communication
• customer inquiries
• supplier invoices.

Businesses often use their principal place of business as their postal address. But you can use a post office box or virtual office service instead for convenience or privacy. This can be a good idea if you run your business from home and don’t want to give out your home address.

You may need to tell the:

• Australian Taxation Office (ATO)
• Australian Securities and Investment Commission (ASIC)
• Australian Business Register (ABR).
