Frequently asked questions
What does BIC 21420 cover?
The code groups business activities under the ATO wording used for tax return workflows. It is the code to use when the business needs a practical industry label, not a broad industry explanation.
How do I know whether this is the right BIC?
Check the parent ANZSIC class, then compare the industry descriptions listed on the page. If the business activity sits elsewhere, the parent ANZSIC class will usually point you to the better match.
Why does the page show nearby BIC codes?
Nearby codes help you compare similar labels and avoid choosing a code that is too broad or too narrow for the underlying activity.
