Using small business CGT exemptions to boost your super

During their working life, many small business owners plough every surplus dollar into their business and then use the proceeds from its eventual sale to pay for their retirement.

This can be a sensible strategy, especially if you take advantage of the various small business capital gains tax (CGT) concessions on offer when you sell. Not only can these concessions significantly cut your CGT bill, but they can also allow you to contribute more money into your super account without having to worry about the normal super contribution limits.

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.

What are the small business CGT concessions?

There are four small business CGT concessions on offer:

  • Small business 15-year exemption (Subdivision 152-B of the Tax Act)
  • Small business 50% active asset reduction (Subdivision 152-C)
  • Small business retirement exemption (Subdivision 152-D)
  • Small business rollover (Subdivision 152-E)

Each concession is available in a different situation. You can apply as many of the CGT concessions to the capital gain from selling your assets as you are eligible for, allowing you to continue reducing your capital gain and the resulting CGT.

Of the four CGT concessions, however, only two come with the extra bonus of allowing you to make larger contributions to boost your retirement savings. These are the:

Which CGT concession applies?

In most cases, the concessions are applied in the following order:

  1. If you qualify for the 15-year CGT exemption, it is applied first. This exemption will disregard the entire capital gain and you do not need to apply any of the other concessions
  2. If you didn’t qualify for the 15-year CGT exemption, the 50% active asset reduction is then applied automatically, unless you choose not to use it
  3. You may then apply the retirement exemption or small business roll-over.

Before applying the 50% active assets reduction, retirement exemption or small business roll-over, you must first reduce your capital gain by offsetting any capital losses and applying the 50% CGT discount for assets owned 12 months or more (if you are eligible for it).

It is not compulsory to apply the 50% active asset reduction. You may choose not to use it if you wish to increase the amount available to use towards the retirement exemption or small business roll-over.

Am I eligible for the small business exemptions?

It’s important to know there are both basic conditions and some specific conditions you need to meet before you qualify for each 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.

See the following articles for specific conditions for each exemption:

Contributing to your super using a small business exemption

If you’re eligible for the 15-year exemption or the retirement exemption, you can 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 a small business exemption when you contribute to your super account, you’re not limited by the normal annual contributions cap applying to non-concessional super contributions. This means you can make contributions that would exceed the usual cap and you can contribute when your total super balance was above the general transfer balance cap on the last 30 June.

Example

Jeremy had a total super balance (TSB) of $2.2 million on 30 June 2025.

The general transfer balance cap for 2025-26 is $2 million.

Because his latest TSB is above the transfer balance cap, Jeremy’s non-concessional contribution cap is zero in 2025-26.

Jeremy is eligible for the 15-year exemption after selling small business assets and making a capital gain of $650,000. He has never previously made a CGT cap election for super contributions.

Jeremy can contribute the full $650,000 to his super account using the CGT cap election to exclude the contribution from his non-concessional cap. Because his contribution doesn’t count towards the cap, he will not exceed it.

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.

How the lifetime CGT cap works

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. This limit is called the lifetime CGT cap.

For example, if you exclude $500,000 from your non-concessional cap using the retirement exemption and then a further $500,000 using the 15-year exemption several years later, you will consume a total of $1 million from your cap.

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

Need to know: The lifetime CGT cap

The CGT cap applies to all excluded CGT contributions made after 30 June 2007. The cap amount is indexed annually.

Income year Amount of cap
2025–26 $1,865,000
2024–25 $1,780,000
2023–24 $1,705,000
2022–23 $1,650,000
2021–22 $1,615,000
2020–21 $1,565,000

 

The lifetime CGT cap amount is indexed in line with average weekly ordinary time earnings (AWOTE), in increments of $5,000 (rounded down).

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 or retirement 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.

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.
