Navigating CGT on Your Home: New ATO Clarity for Home-Based Businesses
Running a business from home—whether as a sole trader, freelancer, or small operator—has many perks. But when it comes to selling your home and potentially saving on tax, recent guidance from the ATO serves as a reality check.
The ATO has provided its views on how home-based businesses interact with the small business capital gains tax (CGT) concessions, providing a warning on how the ATO approaches a long-standing area of confusion.

The Key Issue: Active Asset Test
When an individual sells their main residence, they will often enjoy a full CGT exemption. However, if part of the home is used for business purposes, this can potentially impact on the scope of the exemption.
If a full exemption isn’t available under the main residence rules then we typically look to other CGT concessions, including the CGT discount for assets that have been held for more than 12 months or the small business CGT concessions.
The small business CGT concessions can potentially reduce or eliminate a capital gain made on sale of a property, but only if certain conditions are passed. One of the key conditions is that the property must pass an active asset test.
In very broad terms, to pass the active asset test you need to show that the property has been actively used in a business activity for at least 7.5 years across the ownership period or for at least half of the ownership period.
The ATO is clear: the active asset test applies to the entire property, not just the business portion. When you are applying the active asset test, an asset either passes this test or fails it. It is not really possible for an asset to partially pass the active asset test. The entire property is either an active asset or it is not.
Simply having a home office, workshop, or even being able to claim home occupancy expenses as a deduction does not necessarily make your home an active asset. Where business use is incidental to the home’s primary residential purpose, the ATO’s view is that the small business CGT concessions generally do not apply.
Rus v FCT
The view that the entire property must qualify as an active asset—and that incidental or minor business use (such as a home office or storage in a largely residential setting) is insufficient—draws support from case law, particularly the Administrative Appeals Tribunal (AAT) decision in Rus and Commissioner of Taxation [2018] AATA 1854 (Rus v FCT).
In that case, a taxpayer sought access to the small business CGT concessions on the sale of a 16-hectare largely vacant rural property, where only a small portion (less than 10% by area) was used for business purposes: a home office, shed for storing tools/equipment/vehicles, and related supplies tied to a plastering and construction business operated through a controlled company. The balance of the land remained vacant or used residentially.
The AAT upheld the ATO's ruling that the property as a whole did not satisfy the active asset test, reasoning that the business activities were not sufficiently integral to the asset overall.
Minor or incidental use did not make the entire property an active asset, especially where the business was primarily conducted off-site. This precedent reinforces the ATO's strict approach in home-based business scenarios: the property is assessed holistically. This means that limited business use typically fails to tip the scales toward qualifying for the concessions.
Practical Examples
Let’s take a look at how the ATO approaches some common scenarios.
Minor home-based business: Harriet runs a hairdressing salon in a spare room, using 7% of the total floor space of the property and seeing clients eight hours a week. She claims deductions for occupancy expenses and gets a 93% main residence exemption. However, because her business use is minor, she cannot access small business CGT concessions. The 50% CGT discount can still apply.
Significant business use: Sue and Rob own a two-storey building, with the ground floor operating as a takeaway store (50% of the total floor area of the property) and the top floor as their private residence. The business has been running for decades with employees. Here, the property qualifies as an active asset, potentially giving them access to the small business CGT concessions for the portion of the capital gain that isn’t covered by the main residence exemption.
What This Means for You
· A partial main residence exemption doesn’t necessarily mean you have access to the small business CGT concessions. Many homeowners mistakenly assume that business deductions or a home office automatically open the door. The ATO clearly doesn’t share this view.
· Seek advice before changing the way your home will be used. Starting to operate a business from home can impact on deductions, CGT calculations and access to CGT concessions. We are here to help you make fully informed decisions.
· Keep thorough records. Floor plans, hours of business use, and detailed deductions can help strengthen your position and may help in any future planning or audits.
· Consult your accountant. If selling your home is on the horizon, professional advice is critical to assess any potential CGT exposure and explore concessions that might be available.
The Bottom Line
The ATO’s updated guidance suggests that many home-based business owners won’t have access to the small business CGT concessions on sale of their home, but this always depends on the facts. Business owners need to plan proactively, rather than assume that tax relief will be available.
By understanding how your home’s business use is treated, you can make smarter decisions. For example, will the profits generated from a small business operated at home end up being wiped out by a higher CGT liability on sale of the property down the track?
After all, when it comes to CGT, every dollar you keep counts toward your next venture or your retirement nest egg.
