Small Business Capital Gains Tax Concessions in Australia: Complete Guide for 2026

Small Business Capital Gains

Selling a business or one of its assets can be a big milestone. However, many business owners are surprised by how much tax they may need to pay on the profit, known as capital gains tax (CGT).

The good news is that small business capital gains tax concessions can greatly reduce, or even remove, the tax you owe. These concessions can significantly reduce the tax you pay when selling your business, yet many owners don’t realise they’re eligible. 

In this article, we explain everything you need to know about small business CGT concessions, including eligibility, different types of concessions, examples, and how to apply them step by step.

What are Small Business Capital Gains Tax Concessions?

If you meet the eligibility requirements, you may be able to:

  • Reduce your capital gain
  • Defer your tax liability
  • Eliminate your CGT

These capital gains tax concessions are designed to support business growth, facilitate retirement planning, and ease business transitions.

Why Small Business Capital Gains Tax Concessions Matter

For many business owners, selling a business reflects years of hard work and dedication. Without proper planning, a large part of the profit could be lost to tax.

However, by using ATO small business CGT concessions, you may be able to:

  • Keep more of your business profits
  • Reinvest in new opportunities
  • Plan for retirement more effectively
  • Improve your overall financial position

CGT rules can get complex; many business owners choose accounting outsourcing support to keep their records accurate and ensure everything is handled correctly at tax time. 

When used correctly, these concessions can potentially save business owners hundreds of thousands of dollars. 

The 4 Main Small Business Capital Gains Tax Concessions

There are four key small business capital gains tax concessions available under Australian tax law, each designed to reduce your overall tax liability.

1. 15-Year Exemption

This is the most generous capital gains tax concession.

If you qualify, you can completely disregard your capital gain (100% tax-free).

Key conditions:

  • You must have owned the asset for at least 15 years
  • You are aged 55 or over and retiring, or permanently incapacitated
  • The asset must be an active business asset

This concession is often used when business owners are exiting or retiring.

2. 50% Active Asset Reduction

This concession cuts your capital gain in half, which directly reduces how much tax you pay.

It is one of the most commonly used small business CGT strategies and can be combined with other concessions.

Important: This reduction applies after the general CGT discount (if eligible), leading to substantial tax savings.

3. CGT Retirement Exemption

The CGT retirement exemption allows you to disregard up to $500,000 of capital gains over your lifetime.

Key points:

  • If under 55, the amount must be contributed to superannuation
  • If over 55, you can receive the amount directly
This is also referred to as the small business CGT retirement exemption and is widely used for retirement planning.

4. Small Business Rollover

The rollover concession allows you to defer your capital gain.

How it works:

  • You defer the gain for up to two years
  • You must reinvest in another business asset

This option is useful if you are restructuring or expanding your business rather than exiting.

Basic Eligibility Criteria for Small Business CGT Concessions

To qualify for small business capital gains tax concessions, you must meet specific conditions set by the Australian Taxation Office. These criteria ensure that only eligible small businesses benefit from these valuable tax concessions.

1. A CGT Event Must Occur

CGT event typically arises when you sell, transfer, or otherwise dispose of a business asset. This is the point at which a capital gain or loss is calculated.

2. You Must Have a Capital Gain

The concessions apply only if you make a profit from the transaction. This means the sale proceeds must exceed the asset’s cost base, including purchase price and associated expenses.

3. The Asset Must Be an Active Asset

The asset must be actively used in carrying on your business. To meet the active asset test:
  • It should be used for at least half of the ownership period, or
  • If owned for more than 15 years, it must be used for at least 7.5 years

This is a key requirement for accessing small business CGT benefits.

4. You Must Meet One of the Eligibility Tests

You must satisfy at least one of the following:

  • Aggregated Turnover Test: Your annual turnover is less than $2 million
  • Net Asset Value Test: Your total net assets do not exceed $6 million

Meeting these thresholds determines your eligibility for ATO small business CGT concessions.

Step-by-Step: How to Apply Small Business CGT Concessions

Applying small business CGT concessions in the correct order is essential to maximise your tax savings and remain compliant with the Australian Taxation Office guidelines.

Step 1: Calculate Your Capital Gain

Start by calculating your capital gain. This is the difference between the asset’s sale price and its cost base, which includes the purchase price and associated costs such as legal fees, improvements, and transaction expenses.

Step 2: Apply Capital Losses

If you have any carried-forward capital losses from previous years, deduct them from your current capital gain. This reduces the amount of gain subject to tax before applying any concessions.

Step 3: Apply the CGT Discount

If you are eligible (for example, individuals or trusts holding an asset for at least 12 months), apply the 50% general CGT discount. This step can significantly reduce the taxable portion of your gain.

Step 4: Apply Small Business Concessions

Finally, apply the relevant small business concessions in the correct order:

  • 15-year exemption (if eligible, this can eliminate the entire gain)
  • 50% active asset reduction
  • CGT retirement exemption or rollover

Following this sequence is crucial, as each step builds on the previous one to minimise your overall tax liability. Because these steps must be applied in the correct order, many business owners rely on outsourced tax services to avoid mistakes and make sure they’re not paying more tax than necessary. 

Example: How Much Tax Can You Save?

Let’s look at a simple example.

Scenario:

  • Capital gain: $200,000
  • Capital losses: $20,000

Calculation:

  • Net gain: $180,000
  • Apply 50% CGT discount: $90,000
  • Apply 50% active asset reduction: $45,000
  • Apply retirement exemption: $0 taxable gain

In this case, your small business CGT concessions reduce your tax liability to zero.
