You bought a workshop, built a business, and watched the asset rise in value while you focused on customers, staff, and cash flow. Now retirement is approaching, and the sale price looks attractive, but one question keeps interrupting every conversation: will capital gains tax take a large share of the gain?
The Australian CGT 15-year exemption can disregard the entire capital gain from a qualifying small business asset. It isn’t a partial discount, and it doesn’t require you to calculate a reduced gain after applying another concession. But the conditions are strict. You need the right ownership history, active asset evidence, business size qualification, and retirement connection at the time of the CGT event.
This guide takes a practical path from eligibility to worked dollar examples, common ownership traps, record-keeping, and the private ruling process. If the facts aren’t clear, get the position tested before you sign a binding sale contract.
Why the CGT 15 Year Exemption Matters for Long-Held Australian Small Businesses
Consider a tradesperson who bought a workshop for $180,000 in 2009 and is now considering retirement at 62. A buyer offers $420,000. The apparent capital gain is $240,000, before considering any eligible cost base adjustments. Under ordinary CGT rules, that gain may create a material tax problem at exactly the point the owner wants to convert business wealth into retirement funds.
The small business 15-year exemption can remove the entire capital gain when every statutory condition is satisfied. The ATO describes the concession as applying to a qualifying active asset that has been continuously owned for 15 years, with the active asset test met for at least 7.5 years of that ownership period. At the CGT event, the taxpayer or a significant individual must also be 55 or older and connected with retirement, or permanently incapacitated. See the ATO guidance on the small business 15-year exemption.
That combination makes the concession unusually powerful. If you qualify, the whole capital gain is disregarded. You don’t apply the 50% active asset reduction first, and you don’t need to rely on the retirement exemption to remove the same gain. The result can protect more of the sale proceeds for retirement, debt reduction, or the next stage of family wealth planning.
Practical rule: Treat the exemption as a pre-sale eligibility project, not a tax calculation performed after settlement.
Start with the asset and its ownership history. Then prove business use, test the wider business group and document the retirement connection. A long-held asset can still fail if an ownership change, passive-use period or related-entity issue breaks the required conditions.
The policy history also matters. Treasury material traces the concession to the commencement of CGT on 20 September 1985, with the rules designed to apply 15 years after CGT began in Australia. That history helps explain why the concession focuses so heavily on long-term ownership and retirement.
Eligibility Conditions Every Owner Must Satisfy
The safest approach is a checklist. Every condition matters, and a failure on one condition can prevent the whole exemption from applying.
Start with continuous ownership
The relevant CGT asset must have been continuously owned for at least 15 years before the CGT event. Don’t rely on the age of the business alone. The owner of the business, the owner of the premises and the entity selling the asset may not be the same person or entity.
Shares in a qualifying company or interests in a qualifying trust can involve additional analysis, including the significant individual and concession stakeholder rules. Where a share disposal produces a CGT event such as CGT event E10, check the ownership and control history rather than assuming the operating history proves eligibility.
Prove the active asset period
For an asset owned for more than 15 years, the active asset test generally requires active use for at least 7.5 years during the ownership period. The ATO explains the active asset test for small business CGT concessions.
The analysis can cover business goodwill, land and buildings used in the business, and other qualifying business assets. Trading stock follows different tax treatment and shouldn’t be casually included in a CGT exemption calculation. Gather evidence showing how the asset was used, when that use started, and whether any periods involved private or passive use.
Confirm age, retirement or incapacity
At the time of the CGT event, the taxpayer or relevant significant individual must be 55 or older, and the disposal must be connected with retirement. Alternatively, the person must be permanently incapacitated. Age alone isn’t enough, and a statement that the sale is “for retirement” won’t replace evidence of what happened.
Test the business size
The small business CGT concessions require either:
- Aggregated annual turnover of less than $10 million, or
- Maximum net asset value of less than $6 million immediately before the CGT event.
The turnover test can include connected entities and affiliates. Review the wider group, including related businesses and relevant prior-year turnover, instead of checking only the entity making the sale.
| Condition | ATO Threshold | Quick Self-Check |
|---|---|---|
| Continuous ownership | 15 years | Can you trace uninterrupted ownership of the exact asset? |
| Active asset use | At least 7.5 years across the ownership period | Do leases, accounts, and business records prove active use? |
| Retirement connection | 55 or older and connected with retirement, or permanent incapacity | Can you evidence the retirement circumstances at the CGT event? |
| Aggregated turnover | Less than $10 million | Have you included connected entities and affiliates? |
| Net asset value | Less than $6 million immediately before the CGT event | Have you measured the relevant business assets and liabilities across the required group? |
Use the Australian small business CGT exemption eligibility overview as a starting point, then obtain advice on your actual structure. A self-screen is useful, but it isn't a substitute for tracing documents and testing the legal conditions together.
How the 15 Year Exemption Sits Inside the Small Business CGT Concessions
The 15-year exemption sits within the broader small business CGT concessions framework. The other major concessions include the 50% active asset reduction, the 25% reduction for individuals with aggregated turnover under $2 million, and the $500,000 lifetime retirement exemption.
The ordering matters. If the 15-year exemption applies, the whole gain is disregarded and you don't calculate another small business concession for that gain first. There is no stacking of partial reductions to reach the same result.
| Concession | Trigger | Tax Outcome |
|---|---|---|
| 15-year exemption | Qualifying asset, 15-year ownership, active asset test and retirement or incapacity conditions | Entire capital gain is disregarded |
| 50% active asset reduction | Qualifying small business asset and relevant active asset conditions | Capital gain is reduced by half |
| 25% individual reduction | Individual meets the relevant small business conditions, including the applicable turnover requirement | Further reduction may apply to the remaining gain |
| Retirement exemption | Eligible small business capital gain and individual lifetime limit | Gain can be disregarded up to $500,000 per individual |
The $500,000 lifetime retirement exemption limit is a separate concession, not an additional amount available after the 15-year exemption removes the gain. If the 15-year rule fails, the other concessions may still reduce or absorb part of the gain, depending on the facts.
The right question isn’t “which concession gives me a discount?” It’s “do I qualify for the concession that removes the gain altogether?”
This distinction matters in succession planning, business sales and acquisitions. Anyone reviewing a transaction should assess the tax consequences before the structure is fixed. For broader deal planning, reviewing tax strategies in M&A can help frame the issues that sit around a business acquisition or disposal.
Read the small business tax concessions guidance from EndureGo Tax alongside the ATO material, but don’t treat a general summary as confirmation that your particular company, trust or asset qualifies.
Worked Dollar Examples Showing the Exemption in Action
The numbers become clearer when you follow the asset from purchase to sale.
Example one, a retiring plumbing business owner
A 62-year-old tradie bought a plumbing business for $400,000 in 2008 and sold it in 2024 for $1.6 million. On the simplified facts provided, the capital gain is $1.2 million, before any cost base adjustments.
Assume the owner continuously held the relevant asset for the required period, used it as an active business asset throughout the relevant ownership period, and can prove at least 7.5 active years. Assume the owner also meets the small business size test, with aggregated turnover below $10 million, and retires immediately after the sale.
The calculation is straightforward:
- Sale price: $1.6 million
- Acquisition amount used in this simplified example: $400,000
- Capital gain: $1.2 million
- Active asset period: at least 7.5 years
- Age and retirement: 62 and retiring
- Result under the 15-year exemption: $0 capital gain included
The concession removes the entire $1.2 million gain in this simplified example. The 50% active asset reduction and the retirement exemption aren’t needed for that gain.
Example two, a café owner who sells before satisfying the personal condition
A café owner has held the business asset for 15 years and 8 months. The owner is 54 and plans to keep working after the sale. Even if the ownership period and active asset test are satisfied, the 15-year exemption can’t apply in these facts because the age and retirement condition isn’t met.
Suppose the simplified capital gain is $1.2 million, with at least 7.5 active years and the relevant business size tests satisfied. The owner must examine alternative concessions. The 50% active asset reduction could reduce the gain to $600,000, and the retirement exemption may then provide relief up to the individual’s $500,000 lifetime limit, subject to its own conditions. That outcome requires careful sequencing and cannot be assumed from the 15-year ownership period alone.
| Scenario | Acquisition | Sale Price | Capital Gain | Active Years | 55 or Retired? | Taxable Gain |
|---|---|---|---|---|---|---|
| Retiring plumbing owner | $400,000 | $1.6 million | $1.2 million | At least 7.5 years | Yes | $0 under the 15-year exemption |
| Café owner continuing work | Not specified | Not specified | $1.2 million, simplified | At least 7.5 years | No | Requires alternative concession analysis |
These examples use simplified purchase and sale figures. Real calculations must account for the actual cost base, ownership entity, transaction costs, related-party history, and the precise CGT event.
Common Misconceptions and Ownership-Splitting Traps to Avoid
The most expensive mistakes happen when owners treat the 15-year exemption as a reward for keeping a business open for a long time. It isn’t. The law tests the exact asset, the exact owner, the active-use history, and the circumstances at sale.
Myth one, only part of the gain is exempt
That assumption is wrong. If all conditions are satisfied, the entire capital gain is disregarded. You don’t apply a partial exemption to one portion and tax the balance under ordinary rules.
Myth two, a transfer to family preserves the clock
Transferring the asset to a spouse, family member, company or trust shortly before sale can trigger a CGT event and disrupt the required continuous ownership period. The new owner generally can’t claim the original owner’s history because the family controls both entities.
Don’t restructure a long-held asset casually. A pre-sale transfer may change the taxpayer making the gain, the active asset evidence and the relevant significant individual analysis.
Myth three, a passive related-company asset qualifies
A company connected with the business doesn’t automatically make every asset an active asset. The asset must satisfy the active asset requirements through business use or the relevant affiliate or connected arrangement. A passive investment held by a related company needs its own analysis.
The ATO also applies strict rules where ownership interests have been split or acquired at different times. If you hold separate interests in the same CGT asset and sell them together, only the interests continuously held for at least 15 years can qualify. An interest held for less than 15 years doesn’t inherit the older interest’s history. This issue can arise with jointly held property, staged acquisitions and mixed ownership periods. See the ATO guide on the small business 15-year exemption and separate interests.
Record-Keeping and Private Rulings with EndureGo Tax
A strong CGT position needs evidence, not confidence. Start building the file before the sale process becomes urgent.
Keep:
- Purchase and sale contracts: Retain contracts identifying the asset, parties, dates, and consideration.
- BAS and tax returns: Keep the business reporting history for every year in the relevant ownership period.
- Lease agreements: Use leases and occupancy records to prove active business use of premises.
- Employee records: Rosters, payroll records and employment documents can support the operating history for active-use periods.
- Retirement evidence: Record the intended retirement or cessation circumstances contemporaneously, rather than trying to recreate the story after settlement.
Tax records generally need to be kept for five years from the date the CGT event is assessed, or longer where the position remains contested. Your adviser should confirm the appropriate retention period for the complete file, especially where the asset history or ATO treatment remains under review.
When a private ruling makes sense
Seek an ATO private ruling where the facts are difficult to prove, or the transaction carries significant financial consequences. Typical triggers include an uncertain retirement date, borderline turnover or net asset values, a family trust restructure, separate interests acquired at different times, or a company and trust structure involving several significant individuals.
The process should begin before you sign a binding contract. EndureGo Tax can take an owner through an initial 60-minute scoping call, issue a document collection checklist, draft the ruling request and supporting statements, lodge through the ATO portal, and track the 28-day statutory response window. If the ATO asks for further information, the adviser can coordinate the response and follow up on outstanding issues.
For owners who need a formal ATO position, review the private ruling application service before committing to a sale timetable. A private ruling doesn’t replace accurate facts, but it can address uncertainty while there is still time to change the transaction plan.
Frequently Asked Questions About the CGT 15 Year Exemption
Does the exemption apply to shares in a company?
It can apply in some share disposal circumstances, but the analysis doesn’t stop at the company’s trading history. You need to examine the qualifying company, significant individual, and concession stakeholder requirements, along with the relevant CGT event.
Can I keep consulting after selling the business?
The retirement connection depends on the facts at the time of the CGT event. If you plan to continue working, document the nature and extent of that work before the sale and obtain advice rather than assuming the sale automatically counts as retirement.
What happens if a discretionary trust owns the asset?
A trust-owned asset requires analysis of the trust, the relevant individuals and the distribution or payment pathway. Family control alone doesn’t prove that every statutory condition has been met.
Does the $6 million net asset test cover related entities?
The maximum net asset value test must be assessed using the relevant business group rules, not just the balance sheet of the selling entity. Include connected entities and relevant affiliates in the review.
Do I apply the 50% active asset reduction as well?
No, not for the same gain when the 15-year exemption applies. The whole gain is disregarded, so another concession isn’t required first.
Should I seek a private ruling before signing a contract?
Yes, where eligibility remains uncertain, and the transaction is material. Obtain advice early enough to identify missing records, restructure risks and retirement evidence before the contract fixes the commercial outcome.
For the primary rule, read the ATO fact sheet on the small business 15-year exemption.
