30 June 2027 start-up valuation
Own shares in a start-up? 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 shares or other interests in the company 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.
The line between growth already built and growth still to come.
That could be years away.
The problem? Proving what a private start-up 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
- Before 1 July 2027Value already builtGrowth up to the date keeps the old treatment.
- 30 June 2027Potential valuation dateThe line between the old rules and the new.
- After 1 July 2027Future growthGrowth from here falls under the new rules.
For some owners, being able to show what the start-up was genuinely worth at 30 June 2027 may become important later.

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 start-up 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 a start-up
Start-ups often have little profit and a lot of evidence elsewhere. The question is which evidence existed at the time.
- Funding rounds
- The price and terms of recent rounds, and who invested.
- Cap table
- Who owns what, including SAFEs, convertible notes and options.
- Traction
- Revenue, recurring revenue and growth at the time.
- Runway
- Cash, burn and when the next raise would have been needed.
- Intellectual property
- What the company owns, and whether it is properly assigned.
- Founder dependence
- How much rests on one or two founders.
- Customer contracts
- Signed customers, pilots and pipeline at the time.
Board packs, investor updates and the cap table at 30 June 2027 show what was known then. They are the evidence a later valuation of that date will lean on.
Be prepared
What should I keep?
Financials
- financial statements
- tax returns
- management accounts
- assets and debts
- unusual expenses
Business
- major customers
- recurring revenue
- contracts
- suppliers
- employees
- systems
- IP and licences
Future plans
- budgets
- forecasts
- expansion plans
- genuine business plans that existed at the time
Risks
- customer concentration
- owner dependence
- regulatory issues
- supplier dependence
- known legal or operational issues
Don’t manufacture information later. Preserve what genuinely existed at the time.

If you need it
CGT 2027 Valuation Package
Fixed fee, confirmed in writing on the first call.
One engagement, two dates. We value the company, one class of shares or your own parcel at market value 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
Start-ups get the package at a fixed fee that we confirm in writing on the first call, before any work begins. The fee does not depend on the value we arrive at.
For the update, you provide updated financial information and confirm any material changes to the company. Significant acquisitions, disposals, restructures or scope changes may require a separate quote.
Delivery of the first valuation is agreed before commencement. Delivery time starts once payment and all required information have been received. The update is prepared after 30 June 2027, once you have sent the updated financial information.

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?
Start-ups get the package at a fixed fee that we confirm in writing on the first call, before any work begins. The fee does not depend on the value we arrive at. The fee covers the valuation now and the update to 30 June 2027 at no additional professional fee. Significant acquisitions, disposals, restructures or scope changes may require a separate quote. The start-up fees on our pricing page are for a single valuation at one date.
My shares cost almost nothing. Does that change anything?
Possibly. Founder shares often cost very little, so indexing the cost base adds little, and the market value at 30 June 2027 can carry most of the weight (PwC Australia, 24 August 2026). Your accountant can tell you whether that applies to you.
Is the price of our last funding round the 30 June 2027 value?
Not on its own. A round prices one class of shares, on one date, on that round’s terms. It is evidence we weigh, not the value of an ordinary share at 30 June 2027.
Can you tell our employees or investors what their shares are worth?
We prepare valuations for the company, its board or its advisers, and a report can cover each class on the cap table. We do not advise an employee or investor on whether to buy, exercise, hold or sell, and we hold no Australian Financial Services Licence. Each holder takes their own tax advice.

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.
