Operating a business from your home—whether as a freelancer, sole trader, or small business owner—offers undeniable convenience. Yet, when it comes to selling your property and minimising tax, the Australian Taxation Office (ATO) has recently clarified some important rules that may affect your plans.

The ATO has outlined its position on how home-based businesses interact with the small business capital gains tax (CGT) concessions. This guidance highlights an area that has long caused confusion among taxpayers.

The Core Concern: The Active Asset Test

Typically, the sale of your main residence qualifies for a full CGT exemption. However, if you use any portion of your home for business purposes, this could limit the exemption available.

Where the main residence rules do not provide a full exemption, other CGT concessions may apply. These include the CGT discount for assets held more than 12 months and the small business CGT concessions. The latter can potentially reduce—or even eliminate—the capital gain from selling your property, provided certain requirements are met.

One crucial condition is the active asset test. Broadly speaking, to meet this test, the property must have been actively employed in a business for at least 7.5 years of ownership, or for at least half of the ownership period.

The ATO is clear: the test applies to the entire property, not just the section used for business. An asset either satisfies the active asset test or it doesn’t; partial compliance isn’t recognised. Simply maintaining a home office, workshop, or claiming home occupancy deductions does not automatically qualify your home as an active asset. Where business activities are minor or incidental, the small business CGT concessions usually won’t apply.

Case Law: Rus v FCT

The principle that the whole property must qualify as an active asset, and that incidental business use is insufficient, is supported by the Administrative Appeals Tribunal (AAT) case Rus v FCT [2018] AATA 1854. In this instance, a taxpayer attempted to apply the small business CGT concessions on a largely vacant 16-hectare rural property. Less than 10% of the land was used for business—a home office, a shed for storing tools and vehicles, and supplies for a plastering and construction business. The remainder of the land remained vacant or residential.

The AAT upheld the ATO’s decision that the property did not meet the active asset test. The tribunal found that the business activities were not sufficiently integral to the overall property. Minor or incidental use does not render the entire property an active asset, particularly when the main business operations occur off-site. This case underscores the ATO’s strict approach: the property is assessed as a whole. Limited home-based business use is rarely enough to qualify for the small business CGT concessions.

Practical Scenarios

Minor home-based business: Donald operates a hairdressing salon in a spare room, occupying just 7% of her home and seeing clients eight hours per week. She claims occupancy deductions and receives a 93% main residence exemption. Despite this, her limited business use disqualifies her from the small business CGT concessions. The 50% CGT discount may still apply.

Substantial business use: Janet and Frank own a two-storey property where the ground floor runs a takeaway store (50% of total floor space) while the upper floor is their private residence. With decades of continuous business and employees, the property qualifies as an active asset. This opens potential access to small business CGT concessions for the portion of the capital gain not covered by the main residence exemption.

Key Takeaways

• A partial main residence exemption does not automatically grant access to small business CGT concessions. Home office deductions or minor business use are not sufficient.
  
• Consider your home-use plans carefully. Starting a home-based business can affect deductions, CGT calculations, and eligibility for concessions.
  
• Maintain detailed records. Floor plans, hours of business use, and supporting documentation for deductions can strengthen your position for future planning or audits.
  
• Consult your accountant. Professional advice is critical if selling your home is on the horizon, to assess CGT exposure and identify any concessions that may apply.

Conclusion

The ATO’s guidance makes it clear that many home-based business owners will not automatically qualify for small business CGT concessions when selling their home. Eligibility depends entirely on the specific facts and extent of business use.

Being proactive is essential. Understanding how your property is treated for CGT purposes allows you to make smarter decisions. For example, small business profits generated from your home could be significantly reduced if a higher CGT liability arises upon sale. Every dollar matters, whether it contributes to your next venture or your retirement savings.
