Common Mistakes When Claiming Small Business CGT Concessions

Small business CGT concessions can reduce or eliminate capital gains tax when you sell your business, but missing a single eligibility condition means you pay the full amount.

The concessions operate as a group of four separate reliefs that can be applied alone or stacked together, potentially reducing a capital gain to zero. The 15-year exemption, 50% active asset reduction, retirement exemption (capped at $500,000 per owner), and rollover relief each have distinct eligibility tests. Meeting the basic small business entity test or the $6 million maximum net asset value test is only the starting point. Most claims fail because owners assume eligibility without verifying the active asset test, the significant individual test, or the CGT concession stakeholder requirements that apply to each concession separately.

Active Asset Test Failures That Trigger Full CGT

An asset must be an active asset for at least half the ownership period, or if owned for less than 15 years, for a total of 7.5 years during ownership. An active asset is one used or held ready for use in the business you carry on. Investment properties held for rental income do not qualify. Goodwill and intellectual property held by a separate entity but licensed back to the trading entity often fail this test because the asset is not used in the business of the holding entity.

Consider a software business owner who transferred the company's proprietary code into a family trust three years before sale. The trust licensed the software back to the operating company for an annual fee. At sale, the trust sold the intellectual property separately. The active asset test required the software to be used in a business carried on by the trust. Licensing activity alone did not meet the threshold. The trust did not qualify for the concessions, and the owner paid capital gains tax on the full sale price of the software rights because restructuring occurred too late to satisfy the active asset holding period.

The Significant Individual Test Stops Most Company and Trust Claims

If your business operates through a company or trust, a CGT concession stakeholder must be a significant individual just before the CGT event. A significant individual is someone with a small business participation percentage of at least 20% in the entity claiming the concession. The participation percentage is calculated by tracing voting rights, dividend rights, and capital distributions through all connected entities and affiliates.

This test catches business owners who hold their operating company through multiple trust layers or split ownership across family members to manage income distribution. If no single individual holds a 20% participation percentage when traced through the structure, none of the concessions apply. In structures where ownership is divided among adult children or held through discretionary trusts with broad beneficiary classes, meeting this threshold requires deliberate planning long before sale. Restructuring immediately before sale rarely works because the test applies at the time of the CGT event, and changing control or beneficiary entitlements mid-transaction can trigger other tax consequences or breach sale contract terms.

Net Asset Value Miscalculations Caused by Connected Entities

The $6 million maximum net asset value test includes the net value of assets owned by you, your affiliates, and entities connected with you or your affiliates. Connected entities include companies where you hold at least 40% of shares or voting power, trusts where you control the trustee, and partnerships where you hold a significant interest. Many owners underestimate their net asset value by excluding assets held in related structures.

Family homes are excluded, but investment properties held in a spouse's name count if that spouse is an affiliate. Superannuation fund assets are excluded, but loans owed by the business to a related self-managed super fund increase the connected entity's asset value. Assets used solely to derive rent from a connected entity are excluded under the active asset test, but only if they meet specific criteria. The asset value is calculated just before the CGT event, so timing the sale around other asset purchases or disposals can determine eligibility.

The 15-Year Exemption Requires Continuous Ownership and Retirement

The 15-year exemption offers complete capital gains tax exemption if you continuously owned the asset for at least 15 years, the asset was an active asset just before disposal, and you are aged 55 or over and retiring or are permanently incapacitated. Continuous ownership is measured from when you or your affiliate first held the asset. Transferring an active asset between your individual name, your company, and your family trust during ownership breaks continuity unless specific rollover provisions applied at the time of transfer.

Retirement for this purpose means ceasing all business activities permanently. Selling one business and starting another, even in a different industry, can disqualify the exemption if the connection between the sale and retirement is not clear. Owners over 55 who plan to remain active in consulting, directorships, or new ventures should obtain specific advice about how those activities affect eligibility, rather than assume the exemption applies because they sold the business. For owners under 55 or those not retiring, the other three concessions remain available if eligibility conditions are met.

Restructuring Within Two Years Preserves Concession Access

Ownership structures that fail the significant individual test or split active assets across multiple entities can sometimes be restructured before sale to improve concession access. Rollover relief under the small business concessions allows you to defer capital gains tax when transferring active assets between entities, provided the transaction occurs within two years before the ultimate sale and both entities would qualify for the concessions on disposal.

This allows an owner to consolidate assets into a single entity where they hold sufficient participation percentage, or to transfer assets out of a trust structure into individual ownership where testing is more straightforward. Timing matters because the active asset holding period and 15-year ownership tests continue to apply after restructure. The two-year window is measured from the restructure to the final sale, so planning must begin well before a sale process starts. Restructures triggered after a buyer has been identified or during due diligence rarely provide the intended tax outcome and may raise ATO scrutiny.

Partial Concession Access Through Correct Apportionment

If your business includes both active and non-active assets, or if you meet some but not all eligibility conditions, partial access to the concessions may still be available. The 50% active asset reduction applies only to the portion of the gain that relates to active assets. The retirement exemption applies to the capital gain after all other concessions, meaning you can apply the 50% reduction first and then apply the $500,000 retirement cap to the reduced gain.

Apportionment also applies when an asset was an active asset for part of the ownership period but not the full period. The gain is split based on the proportion of time the asset was active. If you held an asset for 10 years and it was an active asset for 6 years, only 60% of the gain qualifies for concession access. Calculating this correctly requires detailed records of when assets were acquired, how they were used, and when that use changed. Reconstructing this history during a sale process introduces risk because the ATO will request evidence, and approximations are often rejected.

Documentation the ATO Requires to Verify Your Claim

The ATO does not pre-approve small business CGT concession claims, and verification occurs during audit, sometimes years after lodgement. Claims require contemporaneous evidence that the eligibility tests were met at the relevant time. Active asset status requires records showing how the asset was used in carrying on a business, such as business activity statements, financial statements, lease agreements, or operational logs.

Significant individual and connected entity testing requires ownership records, trust deeds, company constitutions, shareholder agreements, and calculations tracing participation percentages through each layer of the structure. Estimating participation percentage without tracing the exact rights at the time of sale creates exposure. Net asset value calculations require valuations or market appraisals for all assets and liabilities across you, your affiliates, and connected entities. Assuming asset values without formal records often leads to disputes, particularly where property or intangible assets are involved.

When engaging with our tax services, we document the concession eligibility position before the sale contract is signed, not during tax return preparation the following year. Attempting to substantiate a claim retrospectively without the correct records means paying capital gains tax on amounts that might have qualified for relief if planning had occurred earlier.

Our team works with business owners to structure transactions and verify eligibility conditions well before the sale process begins, giving you time to address gaps or restructure where needed. Call one of our team or book an appointment at a time that works for you at Book Appointment.
