Who can get an ABN?
Companies that trade in Australia can apply for an ABN. You can also apply for an ABN as an individual or a partnership.
What happens to your company's ACN?
Your ACN is still active and can be used. Your ABN will be based on your company's ACN.
Can I use my ABN instead of an ACN?
You can use your ABN instead of your ACN on company documents and material. You must make sure that:
- your ABN includes your nine digit ACN, and
- the ABN is used in the same places that the ACN is used.
