30 June 2027 business valuation

Own a business? 30 June 2027 could be an important date.

Changes to Australia’s CGT rules start from 1 July 2027. For some owners, the value of your business, shares or other business interests at 30 June 2027 may become important when they eventually sell, transfer or restructure.

Not every owner needs a valuation. Your accountant or tax adviser should first work out whether the new rules apply to you.

Potential valuation date
30June2027

The line between growth already built and growth still to come.

That could be years away.

The problem? Proving what a private business was worth years earlier can be difficult.

So it may make sense to establish and document the value while the evidence is still available.

The simple version

Value already built30 June 2027Future growth
  1. Before 1 July 2027Value already builtGrowth up to the date keeps the old treatment.
  2. 30 June 2027Potential valuation dateThe line between the old rules and the new.
  3. After 1 July 2027Future growthGrowth from here falls under the new rules.

For some owners, being able to show what the business was genuinely worth at 30 June 2027 may become important later.

Two minute check

Could this be worth discussing with your accountant?

Six quick questions. No email needed, and nothing is sent anywhere.

Question 1 of 6
Do you own all or part of a private business?

Timing

Why not just work it out later?

You might be able to. But proving an old value can become much harder.

Your financial statements may survive. The commercial story behind them may not.

The other method

Isn’t there an ATO calculation?

There may be another method for working out how a gain is split over time. But that is different from working out what a private business was actually worth on a specific date.

A calculation

May use information such as:

  • original cost
  • eventual sale price
  • time held

Works backwards from numbers. It does not look at the business.

A business valuation

Looks at the actual business:

  • earnings
  • customers
  • recurring revenue
  • contracts
  • brand
  • intellectual property
  • employees
  • systems
  • owner dependence
  • risk
  • market evidence

A valuation asks: “What was this business actually worth?”

An independent valuation is not designed to produce the highest possible number. It should arrive at the most supportable market value from the evidence available. Which method suits you is a decision for you and your accountant.

Your industry

What a valuer looks at in your industry

What a valuer looks at in a trade or service business

Two plumbing businesses with the same profit can be worth very different amounts. The difference is usually in what happens if the owner steps back.

Maintenance contracts
Recurring service and maintenance agreements that bring work in without a quote.
Customer concentration
How much of the work comes from your top two or three customers or builders.
Staff and subcontractors
Who does the work, how long they have stayed, and who holds the relationships.
Vehicles and equipment
What is owned, what is financed, and what is due for replacement.
Licences
Which licences the business relies on, and whose name they are in.
Owner dependence
Whether the phone keeps ringing if you are not the one answering it.
Pipeline
Quoted, booked and contracted work on the books at the time.
Around 30 June 2027

Your pipeline, contracts and customer list at 30 June 2027 are the commercial story behind that year’s numbers. They are easy to capture at the time and hard to rebuild later.

One engagement, two dates. We value the business now, keep the model and the evidence on file, and update the valuation to 30 June 2027 once the year-end figures exist. A valuation done now is not, on its own, a 30 June 2027 valuation: the included update is.

  • An independent valuation undertaken now
  • The valuation model and supporting evidence established now
  • An updated valuation to 30 June 2027, included at no additional professional fee

For a business with annual turnover of $2 million or more, or a start-up, the same package is available at a fixed fee confirmed in writing on the first call.

For the update, you provide updated financial information and confirm any material changes to the business. Significant acquisitions, disposals, restructures or changes of scope may require a separate quote.

Questions

Plain answers

Does every business need a valuation?

No. It depends on your circumstances. Your accountant or tax adviser should first work out whether the new rules apply to you.

I’m not selling my business. Could this still matter?

Potentially. The value may become relevant later, when a business or business interest is sold, transferred or restructured. Nothing falls due on 30 June 2027 itself.

Does the valuation have to be completed on 30 June 2027?

Not necessarily. Reliable final accounts may only be available afterwards. What matters most is keeping the evidence from the time.

Can my accountant value the business?

Potentially, depending on the circumstances, their competence and independence, and the purpose. For a material value, an independent valuation specialist may give stronger supporting evidence.

Will you calculate my tax?

No. We establish market value. Your accountant or tax adviser decides the tax treatment and works out any tax.

Can I just get a historical valuation later?

Potentially. But rebuilding the commercial position years later can be harder if important records or context are no longer available.

What does it cost?

If you need it, the CGT 2027 Valuation Package is $1,995 + GST for an established business with annual turnover under $2 million. It covers a valuation now and an update to 30 June 2027 at no additional professional fee. A larger business or a start-up gets the same package at a fixed fee confirmed in writing on the first call.

The technical detail, for you and your accountant

What changes

From 1 July 2027 the 50% CGT discount for individuals, trusts and partnerships is replaced by cost base indexation and a 30% minimum tax rate on capital gains. The ATO states that these measures are now law. They apply only to gains that build up after 1 July 2027.

Why 30 June 2027

To separate the two periods, an asset held by an Australian resident individual or trust at the end of 30 June 2027 is generally treated as sold just before 1 July 2027 and bought back on 1 July 2027. The amount used is its market value just before 1 July 2027, or an amount worked out under an apportioning method. No tax falls due on that date: the split is brought to account when the asset is actually sold.

The apportioning method Draft at the review date

The law allows an apportioning method set by legislative instrument. Treasury released a draft on 4 August 2026 for real property and assets without a readily ascertainable market value. Whether to rely on market value or the method is chosen in the tax return for the year of the actual sale, and is a tax decision for you and your adviser.

Companies and pre-CGT assets Part still in consultation

Companies did not have the 50% discount and that does not change. Shares in a private company held by an individual or a trust are assets the new rules apply to. Pre-CGT assets are also treated as sold and bought back at the date. Treasury states that the four small business CGT concessions are staying; some design details were still in consultation at the review date.

What the ATO will and will not do

No valuation carries ATO approval because of who prepared it: the ATO says acceptability usually depends on the valuation process. You can apply to the ATO for a private ruling on an asset’s market value, but it will not give one on the market value for a future event, so no ATO confirmation of a 30 June 2027 value is available before that date.
