The ATO has advised that, if a business hasn’t used its ABN for a while, the ATO may contact them about cancelling their ABN.
The ATO may also contact them about their ABN if their business situation has changed.
To ensure businesses don’t miss out on Government support, including during unfortunate events, it’s essential that they regularly review their ABN details and keep them up to date (or cancel their ABN if the business is no longer operating, so that Government agencies can tailor their support to those that need it).
It’s also important to check that the business has listed the physical address of the business, as otherwise it can be difficult for emergency services and Government agencies to make contact.
A business’ mailing address and physical location address can be listed separately on its ABN data, and these (and other ABN details) can be checked and updated online at any time.
