Cancelling business registrations

Find out what you need to know about business registrations when you close a business.

Last updated 20 August 2026

If your business changes

If your business changes, sells or closes you may need to cancel one or more registrations. What you need to cancel depends on whether the business has permanently closed or is still operating in some way.

What to do before cancelling registrations

Before you cancel any registration, you must:

  • lodge all required activity statements and tax returns
  • pay any outstanding tax debts
  • complete employee obligations, including super and STP (if applicable)
  • repay any refunds you were not entitled to.

You must meet these obligations even if your business is closing.

Cancelling registrations

If your ABN remains active, you may still need to cancel individual registrations you no longer require.

These may include:

You should only keep registrations that are still required for your business activities.

Cancelling registrations does not remove your obligation to:

  • lodge final tax returns and activity statements
  • complete employee and super reporting
  • keep business records for the required period.

You must still meet these requirements after cancelling registrations.

How to cancel registrations

You can cancel registrations:

  • through Online services for business
  • through your registered tax or BAS agent
  • by phoning us
  • by lodging the approved cancellation form.

You can cancel registrations together or separately, depending on your circumstances.

Cancelling your ABN

You need to cancel your ABN if your business is permanently closed or if you've paused trading activities in your business, with the intent of restarting. Cancel your ABN if your business has stopped trading, otherwise you will continue to have lodgment obligations.

When you cancel your ABN, most tax registrations linked to it (such as GST) are cancelled automatically. Don’t cancel your ABN if you are pausing your business and plan to restart later or you still use the ABN for another business.

For all ABNs you must lodge activity statements as required (even if they are nil) and update your ABN details within 28 days of any changes.

Before cancelling your ABN, check your postal address on the ABR is correct, as this is where the cancellation notice will issue.
