Small Business 15-Year CGT Exemption: A Complete Guide for Australians

Running a small business in Australia can be overwhelming, especially when you’ve owned property or assets for a long time. 

Good news is the small business 15-year CGT exemption can provide significant tax relief for eligible business owners. 

This guide will explain what this CGT exemption is, who can benefit and why understanding the details can mean big savings when selling a CGT asset.

What is the Small Business 15-Year CGT Exemption?

If you’re running a small business and have held an active asset – land, property or equipment – for at least 15 years, you may be able to sell it while avoiding any capital gains tax liability on the gain. 

This CGT retirement exemption is part of Australia’s suite of small business CGT concessions designed to help small business owners plan for succession, retirement or business change with less financial burden under the Income Tax Assessment Act 1997.

The 15-Year Exemption creates a CGT event that allows eligible CGT concession stakeholders to achieve tax-free disposal of qualifying business assets.

Who Can Qualify for Small Business 15-Year Exemption?

To benefit from this exemption, several key criteria under Subdivision 152-B need to be met:

Active asset test: The CGT asset undergoing sale needs to qualify as an active asset utilized within your small business operations for no less than half the ownership period. 

Small business entity test: To be eligible for CGT concessions, your enterprise typically requires annual turnover below $2 million, or total net assets valued under $6 million.

Ownership structure: If you operate through a discretionary trust or company, someone holding at least 20% of a company or interest in a trust (a “significant individual”) must be involved as a CGT concession stakeholder.

Specific Conditions for the 15-Year CGT Exemption

Beyond the fundamental criteria outlined in Subdiv 152-B, the 15-year exemption imposes additional stipulations under section 152-125: 

The CGT asset must have been in your possession for a minimum of 15 uninterrupted years leading up to the CGT event. 

When disposing of the asset, you need to be:

• A minimum age of 55 years and divesting for retirement purposes
• Permanently incapacitated and unable to work due to permanent incapacity (no age requirement for this scenario).

For assets held in a discretionary trust or company, that entity must have had a qualifying significant individual with the required percentage of interest for the full 15 years according to small business participation percentages rules.

What Does “In Connection With Retirement” Mean?

Retirement under this rule doesn’t mean you have to leave the workforce forever. It’s about a genuine change in your business involvement – such as moving from full-time management to part-time consulting, reducing hours or handing over the reins to someone else. 

The key is a real, lasting reduction in activity that means you’re stepping back from small business responsibilities, triggering the CGT retirement exemption.

Benefits of the 15-Year Exemption

Here’s why this CGT concession is so popular with CGT concession stakeholders:

No capital gains tax at all: The full capital gain from the sale of your active asset can be ignored for tax purposes, with the entire exempt amount being tax free.

Superannuation strategies: Sale proceeds can be contributed as concessional contributions and non-concessional contributions to your super fund or retirement savings account (up to the lifetime CGT cap), boosting your retirement nest egg beyond the usual limits and considering your Total Superannuation Balance.

Prioritised over other concessions: This exemption takes precedence—you don’t have to use up available capital losses or apply the 50% active asset reduction first.

Special Rules and Scenarios

1. Involuntary Asset Transfers and Rollover Provisions

If your CGT asset is destroyed, compulsorily acquired or transferred during marriage breakdown, special Small Business rollover provisions and marriage breakdown rollover provisions may allow you to combine ownership periods and retain eligibility. CGT event E4 and other rollover provisions can help preserve qualification for the exemption.

2. Deceased Estate Assets and Legal Personal Representative

If the owner of a qualifying active asset dies, certain successors—like beneficiaries, a legal personal representative or testamentary trust—may also access this CGT retirement exemption if the asset is sold within two years of death and other conditions under section 95 are met. The Australian Tax Office has provided guidance in private ruling 1012763304218 on such scenarios.

3. Mixed-Time Asset Interests and Participation Percentage

You own different shares of a CGT asset purchased at different times? The exemption applies only to the parts you’ve held for at least 15 years. Each “interest in the land” is assessed separately based on the participation percentage and cost base calculations.

Example 1 – Retiring Business Owners

Two siblings have managed a landscaping business for 20 years through Jackson Pty Ltd. When they both reach their late 50s and decide to wind back, they sell the headquarters for a big capital gain, the small business 15-year exemption may zero out the capital gains tax—provided they meet all eligibility criteria as CGT concession stakeholders.

Example 2 – Family Farm

A farming couple own rural land as a family business. After a property settlement and marriage breakdown, one continues to run the business solo.

After fulfilling the remaining years to total 15 years’ ownership (including the time held by the ex-partner using marriage breakdown rollover provisions), they sell the farm for retirement and the exemption may apply, wiping out the taxable capital gain and allowing tax free contributions to their super contribution account.

In this scenario with Jackson Pty Ltd as the operating entity, the family business structure would need to meet the individual significant requirements throughout the ownership period.

Why It Matters for Landowners and Farmers

If you’ve held land, farms or business properties across regional Australia, this small business capital gains tax exemption could mean you get to keep more of what you’ve built over decades. 

Transitioning a farm to the next generation, selling commercial property or stepping back from business is so much easier when a possible tax liability is reduced to zero.

The exemption is particularly valuable for Australian resident farmers and CGT concession stakeholders in regional areas who may face Unforeseen Circumstances requiring asset disposal.
