Small business 15-year exemption explained

If you are a small business owner looking to use the capital built up in your business to help fund your retirement, you’re in luck. There are two capital gains tax (CGT) exemptions with the potential to boost your super when you sell your business assets.

This article covers the 15-year exemption (Subdivision 152-B of the Tax Act) which is the most generous of the exemptions.

If you are not eligible for the 15-year exemption you may be eligible for the retirement exemption which you can read about in our guide here.

Need to know

The eligibility criteria for the government’s four small business CGT concessions are very complex. This is an area where it’s vital to get specialist tax advice to ensure you understand how the rules apply to your situation and whether you qualify.

There are also strict rules on the order in which you can apply the concessions and your resulting tax position can vary significantly. Ensure you consult a licensed tax adviser before making any decisions or contributing to your super account.

How does the 15-year CGT exemption work?

The 15-year CGT exemption is the most favourable of the four small business tax concessions and it must be applied first to any capital gain from the sale of your business assets.

Under the 15-year CGT exemption:

  • The entire capital gain you have made on your business over the years is disregarded by the ATO
  • You don’t need to use any capital losses you have accrued to offset the capital gain
  • The entire sale proceeds up to the Lifetime CGT Cap (see section below) can be contributed into your super account and is not counted towards the non-concessional contributions cap.

This concession can be a great way to avoid paying a lot of CGT on the capital gain you’ve built up in your business over the years, while also boosting your super account as you near retirement.

Example

Ayumi is a conveyancing professional who has operated her own business for 20 years. She is thinking about selling the business and retiring.

Ayumi is aged 58 and has an annual turnover under the $2 million threshold for the small business CGT concessions. As a first step towards retirement, Ayumi sells her business premises, resulting in a capital gain of $600,000.

As she satisfies both the basic and additional conditions for the 15-year CGT exemption, her capital gain of $600,000 is disregarded for CGT purposes and her capital losses are not affected. This means her taxable capital gain after the sale is $0.

Over the years Ayumi has contributed very little to her super account, so she decides to make a big contribution from the proceeds of selling her business premises. She takes advantage of the super contribution rules for the 15-year CGT exemption by contributing the $600,000 into her super account.

Ayumi provides her fund with a CGT cap election form prior to making her contribution, to ensure it is excluded from the non-concessional cap..

Am I eligible for the small business 15-year CGT exemption?

Before getting too excited, it’s important to know there are both basic conditions and some specific conditions you need to meet before you qualify for this exemption.

Need to know

The basic conditions are common to all four of the small business CGT concessions.

You must satisfy these basic conditions before checking whether you qualify under the specific conditions applying to each concession.

1. Basic conditions for any small business CGT exemption

You must be one of the following:

  • small business entity with an aggregated turnover of less than $2 million
  • Not carrying on a business (other than as a partner), but the asset you are selling is used in a closely connected small business
  • A partner in a partnership that is a small business entity, and the asset is either:
    • An interest in a partnership asset
    • An asset you own that is not an interest in a partnership asset, but is used in the partnership’s business
  • You satisfy the maximum net asset value test.

In addition, the asset you’re selling must meet the ATO’s active asset test, which requires the asset to be used in the course of carrying on a business, or held for that purpose, or to be an intangible asset inherently connected with your business.

You will meet the active asset test if the asset you owned for more than 15 years was active for at least 7.5 years. For an active asset you owned 15 years or less, the asset must have been active for at least half the test period, which begins when you acquired it and ends either at the CGT event, or when the business ceases if this occurs in the 12 months before the CGT event.

These minimum periods don’t need to be continuous, provided the asset is active for the minimum amount of time in total.

If the asset is a share in a company or interest in a trust, it must meet additional conditions.

If your situation involves a CGT event related to a partnership and the CGT event involved ending your right or interest, it must be a membership interest in the partnership immediately before the CGT event happens. For all other cases, your right or interest must be a membership interest in the partnership immediately after the CGT event happens.

2. Specific conditions you need to meet for the 15-year CGT exemption

  • You (or the significant individual if you are a company or trust) must be
    • 55 years or older and the event happened in connection with retirement, or
    • Permanently incapacitated (no age requirement)
  • You must have continuously owned the CGT asset for the 15-year period ending just before the CGT event happened

A company or trust must have a significant individual for a total of at least 15 years of the whole period of ownership of the CGT asset.

The significant individual does not have to be the same individual for the entire period.

Other rules apply in the case of relationship breakdowns and death. For details, see the ATO website.

Need to know: ‘In connection with retirement’

In determining whether you’re eligible for the 15-year CGT exemption, the ATO looks at whether the sale occurred ‘in connection with your retirement’. To qualify for the asset sale to be in connection with retirement, there must have been a reduction in your working hours, or a significant change in the nature of your activities.

If the asset is sold either before your retirement (such as during the winding down of the business) or after you retire, it may still be considered as occurring ‘in connection with retirement’.

Contributing to your super using the 15-year exemption

If you’re eligible for the 15-year CGT exemption, you can also take advantage of the many benefits of saving for your retirement through the super system. These include a tax rate of 15% on investment earnings in the accumulation phase and 0% in the retirement phase, which compares to your marginal tax rate (plus the Medicare levy) for assets held outside super. In addition, once you reach age 60, withdrawals from your super account are tax free.

If you use money eligible for the 15-year CGT exemption when you contribute to your super account, you’re not limited by the normal annual contributions cap applying to non-concessional super contributions.

Learn more about the non-concessional contributions cap.

To make personal super contributions you must be aged below 75. Your super fund is able to accept your contribution up to 28 days after the end of the month in which you turn age 75. After this point you are ineligible to make further non-concessional super contributions.

Need to know: The super CGT cap

Given the generosity of the rules allowing you to ignore the normal non-concessional contributions cap, there is a limit on the super contributions you can chose to exclude.

The super capital gains tax cap is a lifetime limit. Any previous super contributions you have excluded from your non-concessional cap using the small business retirement exemption or the 15-year CGT exemption are counted towards it. This cap is indexed annually and is $1,865,000 for 2025–26.

If you exceed your Lifetime CGT cap, the excess contributions are counted towards your non-concessional contributions cap and tax penalties may apply.

How do I elect to exclude contributions into my super account?

If you plan to use money eligible for the small business 15-year CGT exemption as a contribution into your super account, you need to fill out the CGT cap election form. This form allows you to make a personal contribution using proceeds from the sale of your small business asset and to exclude them from your non-concessional contributions cap.

This is the same process that applies to the small business retirement exemption.

The completed form must be given to your super fund before or at the time you make the relevant contribution. If you elect to exclude your contributions after they are contributed, the election will be deemed invalid and the contributions will be included in your non-concessional contributions cap.

After you make your election, your super fund will check if it’s valid before recording it. Your fund will then report these contributions separately from your other personal super contributions.

Q&A: Can I still put money into super using the 15-year CGT exemption if I already have $2 million in super?

Q: If I am eligible for the 15 year CGT exemption but I already have $2 million in superannuation accounts can I still deposit the money that is eligible for the CGT exemption into super?

A: It is possible to make contributions to super using the CGT cap election when your total super balance (TSB) is higher than the transfer balance cap (currently $2 million). 

Although the non-concessional contribution cap for the following financial year is zero for individuals who have a TSB higher than the transfer balance cap on 30 June, any contributions made using the CGT cap election are not counted towards the non-concessional cap.

However, making a contribution using the CGT cap election does not increase the amount you may transfer into income streams for retirement. 

It is also important to consider the introduction of additional tax on balances above $3 million.
