A Sydney fintech founder has just closed his seed round and wants to bring on his first four engineering hires. He offers each of them an option package: 40,000 options over four years, exercise price $0.05, the “current market value.” His accountant tells him the grant is tax-free at issue. His employment lawyer tells him to plug it into the company’s ESOP template. Nine months later he moves the operating entity into a Cayman holding company for a US customer contract, and eighteen months after that his lead investor asks — during Series A diligence — whether the options were ever eligible for the startup concession. The answer: they were at grant, they were not from the moment the Cayman parent came in, and none of the employees have been told. Two of them have already exercised, expecting deferred CGT treatment they will not get.
That pattern — treating the startup concession under section 83A-33 of the Income Tax Assessment Act 1997 (Cth) as a set-and-forget shelter — is the most common ESS mistake founders make. The concession is generous, but it is fragile, evaluated at the ESS interest acquisition time, and constrained by a cluster of company- and interest-level conditions that most founders satisfy by accident rather than design.
What the Startup Concession Actually Does
Default ESS taxation under Subdivision 83A-B brings the discount on an ESS interest — shares or options provided to an employee at less than market value — to assessable income in the year of grant. Subdivision 83A-C defers that assessment to a later deferred taxing point (typically vesting, exercise or exit) for qualifying salary-sacrifice, real-risk-of-forfeiture and (before the 2022 amendments) cessation-of-employment plans. Both regimes tax the discount as ordinary income at marginal rates — a brutal outcome for an unlisted-startup employee sitting on paper value with no liquidity.
Section 83A-33 sits inside Subdivision 83A-B but does something different. Where the eligibility conditions are met, the section:
- Reduces the discount included in the employee’s assessable income to nil for a share provided at up to a 15% discount; and
- Treats the ESS interest as acquired for CGT purposes at market value — so the eventual sale is taxed as a capital gain, not as income, with the 12-month CGT discount available (subject to the phase-out described in our earlier post on the CGT discount replacement from 1 July 2027).
For options, the reduction is different but the effect is similar: no upfront tax on the option grant, and no deferred taxing point at exercise — the shares acquired on exercise are simply taken to have been acquired at their market value at the option acquisition time, and everything from there runs through the CGT system.
The practical shorthand: no tax at grant, no tax at exercise, one CGT event at exit. It is the only regime in Australian income tax that puts a startup employee in substantively the same tax position as a founder-shareholder.
The Four Company-Level Conditions
Every one of these is tested at the time the ESS interest is acquired by the employee, and must be satisfied by the employer company and every other company in the same corporate group.
- Not listed. No equity interests in any group member may be listed on any approved stock exchange, in Australia or abroad.
- Under ten years since incorporation. The employer, its holding company (if any), and every subsidiary of the holding company must all have been incorporated within the last ten income years ending immediately before the ESS acquisition year. The clock starts on ACN issue, and it does not reset on a share sale, share split, name change or restructure. A Delaware-flip or Cayman-topco pushed in above the trading entity introduces a new group member with a fresh incorporation date — but the group is only as young as its oldest member.
- Aggregated turnover of $50 million or less. Measured under the aggregated turnover concept in Subdivision 328-C of the ITAA 1997, over the income year before the acquisition year. Group-consolidated, associate-inclusive, and inclusive of connected entities.
- Australian-resident employer. The company issuing the ESS interest must be a resident of Australia for tax purposes. The condition applies to the issuer, not the ultimate parent — so a US Topco with an Australian trading subsidiary can grant options out of the Australian subsidiary and satisfy this requirement.
The Three Interest-Level Conditions
Distinct from the company tests, and each carrying its own drafting consequence:
- The 15% discount cap (shares) / market-value strike (options). For a share, the discount from market value at acquisition cannot exceed 15%. For a right to acquire a share — a plain-vanilla option — the exercise price must be at or above the market value of an ordinary share in the company at the option’s acquisition time. There is no equivalent of the 15% headroom for options. Zero-strike options are ineligible.
- The 10% ownership and voting cap. The employee — aggregated with their associates — must not, immediately after the ESS interest is acquired, hold either legal or beneficial ownership of more than 10% of the shares in the employer, or more than 10% of the votes exercisable at a general meeting. This bites hardest on early hires who accepted equity as part of their compensation before the option grant, and on senior operator-founders who joined post-incorporation but pre-seed.
- Three-year holding (with the cessation escape). The scheme must be operated so that the ESS interest — or the share acquired on exercise — cannot be disposed of for at least three years after the acquisition time, subject to earlier disposal on cessation of employment. Genuine holding restrictions in the plan rules are essential; a plan that permits voluntary early sale fails this condition even if no employee actually sells.
Valuation: LI 2025/16 Replaced the 2015 Instrument
The 15% discount and market-value exercise-price tests both require the company to establish the market value of an ordinary share at the ESS interest acquisition time. From 1 October 2025, the Income Tax Assessment (Methods for Valuing Unlisted Shares for the Employee Share Scheme Start-up Concession) Determination 2025 (LI 2025/16) replaced the sunset ESS 2015/1 instrument and now provides the two safe-harbour methods that bind the Commissioner where their conditions are met.
- Method One (net tangible assets). Adjusted balance-sheet-derived value, appropriate where the company has meaningful assets and predictable liabilities.
- Method Two (comprehensive method). A more forward-looking multi-input calculation appropriate for companies whose value sits in intangibles, IP or growth expectations.
Where the safe-harbour cannot be used — for example, because a recent third-party priced round establishes a materially different market value under the market evidence rules — a formal 409A-style independent valuation is the safer route. The founder shortcut of using “the seed round price” as market value survives audit only where the seed round is genuinely contemporaneous with the ESS grant and the security terms are equivalent, which they rarely are (preference shares priced round vs ordinary shares granted to employees is the classic mismatch).
Where the Concession Breaks
The three fact patterns we see most often in Series A diligence:
- Post-grant restructures. A Cayman or Delaware Topco pushed in above the trading entity introduces a foreign, non-resident company to the group. Subsequent option grants out of the Australian subsidiary can still qualify, but pre-restructure grants must be tested at their own acquisition time — and the eligibility conclusion drawn then does not need to be revisited. Communicating that split to affected employees is the fix; retrospective re-characterisation is not.
- Cross-year turnover creep. A company whose aggregated turnover was $47m in the FY26 income year and $54m in FY27 can grant startup-concession options at any point in FY27 and still satisfy the turnover test, because the test bites on the prior income year. Grants made in FY28 are ineligible. Founders regularly get the year wrong.
- The 2022 Corporations Act reforms are not a tax carve-out. The Div 1A of Pt 7.12 disclosure exemptions introduced by the Treasury Laws Amendment (Cost of Living Support and Other Measures) Act 2022, in force since 1 October 2022, made it easier to offer ESS interests without a prospectus — but they say nothing about Division 83A. A company can be Corporations-Act-compliant on its ESS offer and still deliver an income-tax outcome to its employees that is nothing like what the founder promised.
What Founders Should Do
Fix eligibility at the incorporation and cap-table design stage, not at the point of grant. Choose an Australian trading company that can carry the ESOP without a foreign parent. Model the 10-year and $50m turnover clocks against realistic growth projections and identify the point at which the concession will run out. Adopt a plan document with drafting that satisfies the three-year holding condition and preserves the concession’s availability for future grants. Use LI 2025/16 for valuation where its conditions fit; commission an independent valuation where they do not. And, once the ESS interests have been granted, follow through with the annual ESS statement and ATO reporting obligations discussed in our next post on employer reporting — because a defensible section 83A-33 position lost at the reporting stage is just as expensive as one lost at the grant stage.
The Bottom Line
The startup concession is Australia’s answer to the US Section 83(b) election and the UK EMI scheme — and, in outcome for the employee, better than either. The mistake founders make is treating it as automatic. It is a set of tightly-drafted eligibility conditions that must be positively evidenced at every grant, that survive corporate group changes only when the changes are structured with the concession in mind, and that turn on a valuation methodology that changed materially on 1 October 2025. The founders who deliver the outcome their employees expect are the ones who treat the ESOP as a tax structure first and an HR document second.
