When to cancel GST registration after closing
GST registration after closing must be cancelled by applying within 21 days of stopping business activities when a business permanently closes, the ATO says. The closing review should separately consider GST or CGT on assets sold and whether retained assets with previously claimed GST credits require an activity-statement adjustment.

How are retained assets treated after GST cancellation?
A business that cancels GST registration while retaining assets may need to repay some GST credits previously claimed for those assets. The review depends on the asset’s GST credit history, its value and the relevant adjustment periods, so cessation of trading alone does not settle the activity-statement treatment.
The ATO’s retained-assets guidance states: “If you cancel your GST registration and still have business assets for which you previously claimed GST credits, you may need to repay some of those credits.” That makes an asset-by-asset review important when preparing closing records.
The ATO’s guidance was updated on 14 September 2026. It explains that the first adjustment period is the first June tax period at least 12 months after the tax period in which an asset was purchased or imported.
For assets not used for business finance, the ATO sets the number of adjustment periods by GST-exclusive purchase or importation value. The following thresholds are published in the ATO guidance.
| Purchase or importation value, less GST | Number of adjustment periods |
|---|---|
| $1,001 to $5,000 | 2 |
| $5,001 to $499,999 | 5 |
| $500,000 or more | 10 |
The same ATO material gives a separate car example. GST credits do not need to be repaid where a car has been held for more than 5 complete financial years.
What should be checked in the asset review?
Practices should identify whether each closing-business asset was sold, retained, disposed of or requires further enquiry, then locate the records supporting any GST credits claimed. This creates a documented basis for considering adjustment periods and prevents the activity statement from being treated only as a record of the business’s final sales and purchases.
- Extract the fixed-asset register and reconcile it to the ledger.
- Mark each item as sold, retained, disposed of or requiring further enquiry.
- Locate purchase records and identify GST credits previously claimed.
- Compare retained assets with the relevant ATO adjustment-period thresholds.
- Document the activity-statement treatment and retain supporting working papers.
The ATO’s example of Graham’s farm improvements shows that the adjustment was reported in a quarterly activity statement for the period ending 31 December 2013. In that example, fencing and a dam purchased in March 2010 were each above $5,000 GST-exclusive, placing them in the five-adjustment-period category.
Assets sold as part of a closure require a separate review from assets retained. The ATO says to check GST or capital gains tax on business assets sold, including land, buildings and intangible assets such as patents, licences and goodwill.
For land or buildings, the ATO describes the margin scheme as an alternative method for calculating GST payable when property is sold as part of a business. Its availability should be considered from the property facts rather than assumed because the business is closing.
Which registration details need separate attention?
The ATO requires changes to registered business details to be reported to the Registrar of the Australian Business Register within 28 days, including changes to an address, associates or main business activity. This obligation concerns registered details and should be tracked separately from the asset review and any GST-registration action.
The ATO’s update-details page lists postal, email and business addresses, associates and main business activity as details that may change. Updates can be made through the Australian Business Register, Online services for business, by phone for authorised contacts, or with the Change of registration details form.
Other registrations may also need their own review. The ATO notes that cancelling GST registration may affect some, but not all, registrations, including fuel tax credits, luxury car tax and wine equalisation tax.
Business-name administration is another distinct matter. ASIC identifies circumstances in which it may cancel a business name, including where it is satisfied that the entity has not carried on business under that name for the previous 3 months.
What belongs in the closure working papers?
The closure file should retain the asset register, purchase records, GST credit history, adjustment-period analysis and activity-statement conclusion. It should also record changed business details and the method used to update them, allowing reviewers to distinguish asset treatment, registration administration and business-name matters.
Clear working papers are particularly useful for vehicles, plant, property improvements and intangible assets. They can show the purchase value, whether a GST credit was claimed, the applicable adjustment-period analysis and the basis for the treatment adopted.
For repetitive information handling, DeskMate takes gathering, chasing, matching and formatting work; it drafts rather than commits, and a person approves before anything becomes final. See what DeskMate automates and its guide to project management for accounting firms.
Keeping asset evidence, registration updates and review notes in one dated workflow helps the practice identify what has been checked before closing work is finalised. It also provides a clearer handover record where more than one team member reviews the client file.
