If you’re selling a business asset or planning to exit your business, understanding the small business capital gains tax (CGT) concessions available under Australian tax law could save you hundreds of thousands of dollars. These concessions—found in Division 152 of the Income Tax Assessment Act 1997—can reduce, defer, or completely eliminate your capital gains tax liability.

This guide explains everything you need to know about small business capital gains tax concessions in Australia: who qualifies, which concessions apply, how to combine them, and what mistakes to avoid.

💡 Planning Tip: Start tax planning 12–24 months before selling a business asset. Meeting the ownership period requirements, organising your records, and selecting the optimal combination of concessions takes time. Waiting until after a sale contract is signed can disqualify you from key benefits.

 

What Are the Small Business CGT Concessions?

The small business CGT concessions are a set of four tax concessions under Division 152 of the ITAA 1997. The Australian Tax Office (ATO) designed them to help small business owners retain capital for reinvestment, retirement, or future business growth when disposing of active business assets.

The four concessions are:

  1. 15-Year Exemption – A complete CGT exemption for assets held for at least 15 years, where the owner is 55 or older and retiring (or permanently incapacitated)
  2. 50% Active Asset Reduction – A 50% reduction in the capital gain, available for eligible active assets
  3. Retirement Exemption – An exemption on capital gains up to a $500,000 lifetime cap, with a super contribution requirement for owners under 55
  4. Small Business Rollover – A deferral of all or part of a capital gain when proceeds are reinvested into a replacement asset or capital improvement

 

Who Qualifies? Basic Eligibility for Small Business CGT Concessions

Before accessing any small business CGT concession, you must satisfy two basic conditions:

1. Small Business Entity Test

You must be a small business entity, which means:

  • An individual, partnership, company, or trust with an aggregated annual turnover below $2 million, OR
  • Your net asset value (including connected and affiliated entities) is under $6 million

2. Active Asset Test

The asset being sold must pass the active asset test—it must have been genuinely used or held ready for use in your business. Key points:

  • The asset must have been active for at least half of the ownership period (where owned more than 15 years, the last 7.5 years is tested)
  • Depreciating assets used for non-business purposes do not qualify
  • Additional rules apply if you’re selling shares or trust interests—these must satisfy specific “connected entity” tests

 

The Four Small Business Capital Gains Tax Concessions Explained

1. The 15-Year CGT Exemption

The 15-year exemption is the most powerful of the four small business CGT concessions. If you qualify, your capital gain is completely disregarded—no CGT applies at all.

To qualify, you must:

  • Satisfy the basic eligibility conditions above
  • Have owned the asset continuously for at least 15 years
  • Be aged 55 or over and retiring, OR be permanently incapacitated
  • Be acting “in connection with retirement”

For companies or trusts, a “significant individual” (a person with at least 20% stake) must meet the age and retirement/incapacity conditions, and must have been a significant individual for at least 15 years.

Note: The 15-year ownership period can include time counted under rollover provisions, such as following relationship breakdown.

Because the gain is fully disregarded, you don’t need to apply capital losses or the general CGT discount after using this concession.

2. The 50% Active Asset Reduction

If your asset passes the active asset test, you’re entitled to a 50% reduction in your capital gain. This is:

  • Automatic unless you elect to opt out
  • Additional to the general 50% CGT discount available to individuals and trusts
  • Particularly powerful when combined with other small business CGT concessions

You may choose to opt out if applying the retirement exemption or small business rollover produces a better outcome for your specific situation.

3. The Retirement Exemption

The retirement exemption allows eligible individuals, or concession stakeholders in companies and trusts, to exempt up to $500,000 of capital gains over their lifetime.

Key rules:

  • The $500,000 is a lifetime cap across all years and assets
  • If you are under 55 at the time of the disposal, the exempt amount must be contributed to a complying superannuation fund or retirement savings account (RSA)
  • If you are 55 or over, no super contribution is required—you can keep the funds
  • Often applied after the 50% active asset reduction to eliminate remaining gain

The retirement exemption is frequently used in combination with the 50% active asset reduction to eliminate tax entirely on a capital gain.

4. The Small Business Rollover

The small business rollover allows you to defer all or part of a capital gain if you reinvest the proceeds into a replacement active asset or make capital improvements to an existing active asset.

Key conditions:

  • The replacement asset must be acquired, or the improvement made, within two years of the disposal (or such longer period as the ATO allows)
  • The deferred gain is not eliminated—it’s triggered when you eventually dispose of the replacement asset, or if the asset ceases to be an active asset
  • The rollover is particularly useful when you want to keep capital working in your business rather than taking a tax hit during reinvestment

How to Apply the Concessions: Order of Operation

If you qualify for more than one concession, the ATO requires them to be applied in a specific sequence. Here’s the correct order:

  1. Apply the 15-Year Exemption first (if eligible—gain is fully disregarded)
  2. Apply the 50% Active Asset Reduction (reduces remaining gain by 50%)
  3. Apply the Retirement Exemption or Small Business Rollover (as applicable)
  4. Offset any available capital losses
  5. Apply the general 50% CGT discount (for individuals or trusts)

Important: Capital losses do not need to be applied before the 15-Year Exemption. If the gain is fully disregarded, losses are preserved for use against other gains.

Combining Small Business CGT Concessions: Real-World Case Studies

📘 Case Study 1: Full Exemption Using the 15-Year CGT Exemption

Background: Angela is a 59-year-old sole trader who has operated a Sydney landscaping business for 18 years. She sells commercial premises used exclusively by her business for $800,000.

Eligibility:

  • Over 55 and retiring ✔
  • Owned the asset for over 15 years ✔
  • Meets the small business turnover test ✔

Outcome: Angela qualifies for the 15-Year CGT Exemption. The entire capital gain is disregarded—she pays $0 in CGT.

Takeaway: A full exemption is available for long-term business owners who are retiring and meet the age and ownership conditions. For business owners in Sydney planning retirement, this is the most valuable of the four small business CGT concessions.

📘 Case Study 2: Combining the 50% Reduction and Retirement Exemption

Background: David owns a Sydney plumbing company with a $1.5 million turnover. After 10 years, he sells the business goodwill for a $400,000 capital gain. He is 52 and not yet retiring.

Concessions applied:

  1. 50% Active Asset Reduction: $400,000 → $200,000 remaining gain
  2. Retirement Exemption: David claims the remaining $200,000. Because he is under 55, he must contribute $200,000 to his superannuation fund.

Outcome: David pays $0 in CGT and adds $200,000 to his super.

Takeaway: Combining these two small business CGT concessions eliminates the entire tax liability while building retirement savings—even before the business owner retires.

📘 Case Study 3: Using the Small Business Rollover During Asset Replacement

Background: Sophie owns a bakery in suburban Sydney and sells one of her delivery vans, generating a $30,000 capital gain. She uses the proceeds to purchase a new van for the business.

Concession applied: Small Business Rollover—the $30,000 gain is deferred.

Five years later: Sophie sells the replacement van without reinvesting. The deferred $30,000 gain becomes taxable at this point.

Takeaway: The rollover delays tax but does not eliminate it. It’s a useful cash flow tool when replacing business assets, but the gain eventually comes due.

Interaction with the General CGT Discount and Capital Losses

The small business CGT concessions interact with the broader CGT rules in important ways:

  • The general 50% CGT discount (available to individuals and trusts for assets held over 12 months) applies after small business concessions and capital losses
  • Capital losses must be offset against gains before the CGT discount is applied (but not before the 15-Year Exemption)
  • Combining the 50% Active Asset Reduction with the 50% CGT discount can reduce a gain by 75% before the Retirement Exemption is applied

Example:

A sole trader sells an active asset for a $100,000 gain. They have a $10,000 capital loss available.

  • Step 1: 50% Active Asset Reduction → $50,000
  • Step 2: Offset $10,000 capital loss → $40,000
  • Step 3: 50% General CGT Discount → $20,000 taxable gain
  • Step 4: Retirement Exemption → $0 taxable gain (if within lifetime cap)

Reporting Your Small Business CGT Concessions

Correct reporting is essential. The ATO scrutinises claims under Division 152 closely.

For individuals and partnerships: Report using the supplementary sections of your individual tax return, including Schedule of Capital Gains if required.

For companies and trusts: You must complete a CGT schedule.

Common mistakes to avoid:

  • Misunderstanding whether you meet the aggregated turnover or net asset value threshold
  • Incorrectly calculating the general CGT discount
  • Failing to document the purchase and sale dates of assets accurately
  • Misapplying rollover rules or failing to reinvest within the required timeframe
  • Exceeding the $500,000 lifetime cap on the Retirement Exemption without realising it

When Should You Start Planning for Small Business CGT Concessions?

The best time to plan is 12–24 months before any disposal. This allows you to:

  • Verify you meet the aggregated turnover and net asset value thresholds
  • Confirm the active asset test will be satisfied
  • Meet the 15-year ownership period (where close to eligible)
  • Elect the most beneficial combination of concessions
  • Organise accurate records of dates, valuations, and ownership structures
  • Make super contributions if required under the Retirement Exemption

Many business owners lose access to significant tax savings by acting too late, often after contracts are signed.
