If your employer has offered you shares or options “at a discount” — or as part of your salary package — here’s the sentence that catches most people out: the tax bill usually arrives long before you sell anything. Under Australia’s employee share scheme (ESS) rules, the “discount” is taxed as income at your marginal rate in the year it crystallises, and capital gains tax only covers what happens afterwards. Get the scheme type wrong, or miss the taxing point, and you can owe tens of thousands with no sale proceeds to pay it.
This guide walks through the three ESS types with every rule worked in real 2026-27 dollars — the maths no competitor does.
The quick answer
- Taxed-upfront: the discount is assessable income in the acquisition year. A $1,000 reduction applies if adjusted taxable income is $180,000 or less and conditions are met.
- Deferral schemes: tax waits until the ESS deferred taxing point — forfeiture risk and disposal restrictions lift, or 15 years pass. Leaving your job is no longer a taxing point (since 1 July 2022).
- Start-up concession: for qualifying early-stage companies the discount is excluded from income entirely. You pay CGT only on sale — the 50% discount clock runs from grant.
- After the taxing point: later growth is taxed under normal CGT — but deferral schemes reset your cost base and 12-month clock at the taxing point.
From 1 July 2027, the general 50% CGT discount is replaced by CPI indexation plus a 30% minimum tax — which affects the later-sale leg of every ESS interest. More on that below, and see our full CGT reform 1 July 2027 guide for the mechanics.
The three ESS types in 60 seconds
Division 83A of the Income Tax Assessment Act 1997 sorts ESS interests into three concessional buckets — plus a non-concessional fourth with no concessions.
| Scheme type | When is the discount taxed? | Concession |
|---|---|---|
| Taxed-upfront | In the year you acquire the interest | Up to $1,000 off the assessable discount (income test applies) |
| Deferral (tax-deferred) | At the ESS deferred taxing point (up to 15 years later) | Delay; tax computed on the market value at the taxing point |
| Start-up concession | Never, as income — CGT only on sale | Discount excluded from assessable income entirely |
| Non-concessional | At acquisition, like taxed-upfront | None — no $1,000 reduction |
Taxed-upfront schemes and the $1,000 reduction
In a taxed-upfront scheme, the discount is included in your assessable income in the year you acquire the ESS interest — shares issued below market value or options with a below-market strike.
The relief is a reduction of up to $1,000 (can’t reduce below nil). To qualify, adjusted taxable income must be $180,000 or less — broader than taxable income: it adds reportable fringe benefits, reportable employer super, net investment losses and net rental losses. Your employer reports the gross discount (they don’t know your income); myTax works out the reduction.
The scheme must also meet further conditions — ordinary shares, the 10% ownership/voting-rights test, and broad employee availability (at least 75% of permanent employees with 3+ years’ service). Fail the conditions and it’s a non-concessional scheme: discount assessable at acquisition with no $1,000 reduction.
Deferral schemes: the deferred taxing point
Deferral schemes push the tax bill to the ESS deferred taxing point — the earliest of:
- no real risk of forfeiture and no genuine restriction on disposal (for rights, disposing of the right);
- the end of the 15-year period starting when you acquired the interest;
- for rights only: exercising the right, where the resulting share carries no forfeiture risk and no disposal restriction.
The myth-bust: quitting no longer triggers ESS tax
Older guides still say leaving the company triggers ESS tax. That ended on 1 July 2022, when ceasing employment was removed as a deferred taxing point for all interests, whenever granted. You can still forfeit unvested interests under the plan rules, but the tax trigger is gone.
The taxable amount — measured at the taxing point, not at grant
At the deferred taxing point, the assessable discount is the market value of the ESS interest at that time, minus its cost base (what you paid plus certain costs). If the share price tripled since grant, so did your tax. Here’s what that looks like in dollars.
Worked example: the vesting shock
Priya earns $140,000. In FY2022-23 her ASX-listed employer granted her 5,000 options at nil cost under a deferred scheme; vesting after three years, no disposal restriction afterwards.
- At the deferred taxing point the 5,000 shares are worth $55,000 → assessable discount $55,000.
- Taxable income becomes $195,000 — top bracket, 47% (45% + 2% Medicare).
- Extra tax: 47% × $55,000 ≈ $25,850.
Priya owes nearly $26,000 with no sale proceeds — the tax falls due because the taxing point occurred, not because she sold. The standard defence is a sell-to-cover at vesting: sell enough shares on the day to fund the bill. Check your own marginal-rate arithmetic on our income tax calculator.
The 30-day rule: shifting the tax year
Here’s a planning lever most guides underplay: if you dispose of the ESS interest within 30 days after the deferred taxing point, the taxing point shifts to the disposal date (s83A-120) — moving the ESS income into the next financial year.
Worked example: the FY shift
Marco’s deferred taxing point lands on 28 June 2027 (vesting + restriction lift) with his interests worth $40,000 — a $40,000 discount on nil cost. Without action, it’s FY2026-27 income. Instead he sells on 10 July 2027, within 30 days.
- The taxing point shifts to 10 July 2027 → the $40,000 ESS discount falls in FY2027-28.
- If the employer already issued the FY2026-27 ESS statement, it must be amended — so warn payroll before year-end statements go out.
- He is deemed to re-acquire at the 10 July 2027 market value (see the CGT section) — selling that day leaves little extra gain, and the 50%-discount clock starts on 10 July 2027.

The start-up concession: $0 tax until you sell
The most generous treatment is reserved for genuine early-stage companies: if the company and scheme meet the conditions, the upfront discount is excluded from assessable income entirely — nothing to pay until you sell, then normal CGT only.
The company must tick all four boxes
- Unlisted — no interests on an approved stock exchange in the prior income year (across the whole corporate group).
- Incorporated less than 10 years ago (whole group).
- Aggregated turnover under $50 million in the income year before the grant year.
- Australian resident taxpayer (the employing company, if different from the granting company).
The scheme must tick its own boxes
- Ordinary shares only; available to at least 75% of Australian employees with 3+ years’ service; employee holds under 10% of shares/voting rights; 3-year minimum holding.
- Shares: discount of 15% or less of market value. Rights/options: exercise price at or above the market value of the underlying share.
- Integrity rule: the employer can’t be a share-trading company.
Cost base and CGT rules for the start-up concession
- Shares: cost base is the market value of the share at acquisition (the market-value substitution rule) — not what you paid, because the discount was never taxed.
- Rights sold unexercised: cost base is only what you paid to acquire and sell the right.
- Rights exercised, then the resulting shares sold: the exercise price is added to the cost base.
- The 50% CGT discount applies as normal over 12 months — with the acquisition date taken as the date the right was acquired. Exercise does not restart the clock.
Worked example: start-up options in dollars
Tom joins an eligible unlisted start-up (turnover $12m, incorporated 4 years ago) and receives options over shares worth $25,000 at grant, exercise price at market value, all conditions met.
- Upfront ESS tax: $0. The discount is excluded from income — nothing on his ESS statement, nothing at Question 12.
- Three years later he exercises, paying a $5,000 exercise price, then sells the shares 18 months later for $90,000.
- Cost base = $5,000 (exercise price; the $25,000 grant value never enters it).
- Gain = $90,000 − $5,000 = $85,000. Held from the right’s grant date — over 12 months — so the 50% discount applies: $42,500 net capital gain assessable that year.
Under a deferral scheme, growth like this would have been income-taxed at the taxing point at up to 47% with no discount; under taxed-upfront, the $25,000 grant discount would have been assessable income that year (less the $1,000 reduction if eligible). The concession is worth real money — hence the strict conditions.
CGT after the ESS taxing point — and the clock reset
Once the ESS discount has been income-taxed, later growth is ordinary CGT — but the cost-base rules differ by scheme, and deferral schemes carry a surprise: the re-acquisition rule.
- Taxed-upfront: taken to have acquired at market value on the acquisition date; later sale → normal CGT from that base.
- Deferral scheme: taken to have re-acquired immediately after the deferred taxing point — cost base and acquisition date reset, so the 12-month 50%-discount clock starts at the taxing point, not at grant.
- Start-up concession: per the rules above — the right’s grant date starts the clock.
In dollars: your deferred-scheme interests are worth $40,000 at the taxing point and you sell six months later for $46,000. The capital gain is only the $6,000 of post-taxing-point growth — but no 50% discount, because the clock started six months ago, not at grant. Sell 14 months after the taxing point and the discount applies. Getting the start date wrong is an expensive error; see our 50% CGT discount guide for the rule in full.
If your ESS shares fall below their re-acquired cost base, the capital loss follows the normal capital loss carry-forward rules — offset against capital gains, carried forward indefinitely, never against salary income.
The “30% ESS CGT discount” — it doesn’t exist (and where the 30% really comes from)
You may see references to a 30% CGT discount for ESS interests. To be blunt: no such discount exists in current law. The ATO applies the standard 50% Division 115 discount to ESS shares held over 12 months — nothing else. The number 30% comes from two nearby places:
- The 1 July 2027 CGT reform: the general 50% discount is replaced by CPI indexation plus a 30% minimum tax on net capital gains — ESS shares sold on or after that date fall in like any other asset.
- A proposed Treasury “Innovative Business CGT Concession” (IBCC): a 2026 consultation paper (not law) floated a targeted concession for start-up investors — including ESS/ESOP participants — for shares issued after 30 June 2027 by unlisted independent companies under $50m turnover and under 10 years old. Proposed design: the 50% discount without the minimum tax, or indexation with it. Proposed only — not enacted as of October 2026.
If you hold start-up-concession shares issued after 30 June 2027, the IBCC is the policy to watch — the one route that could preserve a 50%-discount-style outcome under the reform. Our CGT reform guide tracks the transition.
ESS reporting: statements, pre-fill, and the missing data trap
- Your employer must give you an ESS statement by 14 July after year end, showing the discount and scheme category.
- The employer files an ESS annual report to the ATO by 14 August.
- myTax pre-fills from mid-August — always reconcile it against your own ESS statement.
- Start-up concession discounts never appear on ESS statements and are not entered at Question 12 of the return. If you’re staring at an empty pre-fill wondering where your start-up options went — that’s why.
- ESS discounts go at Question 12 of the individual return.
- If an associate (spouse, child, trust) acquired the interest in relation to your employment, you report the discount.
- Foreign employers may not issue statements at all. Keep the grant documents in writing — the ATO still expects the numbers at Question 12.
Note: the 2026-27 myTax instructions weren’t published at the time of writing — confirm the Question-12 mechanics at lodgement time. The ATO’s employee share schemes page and ESS terms glossary carry the authoritative detail.
Common ESS mistakes
- “I’ll pay tax when I sell.” For upfront and deferral schemes the discount is taxed at grant or at the deferred taxing point — the sale is only the CGT leg. Budgeting for a sale-year bill but getting a vesting-year bill is the classic disaster.
- Trusting stale “quit = tax trigger” advice. Since 1 July 2022, ceasing employment is not a deferred taxing point. Old plan documents and accountant notes are out of date.
- “My options were granted at market price, so there’s no discount.” The option itself has value — a market-value strike can still carry a taxable discount. Get a valuation or use the ATO safe-harbour method.
- Accepting the pre-fill blindly. Start-up concessions never pre-fill; employer statements sometimes don’t match. Reconcile before you lodge.
Tips that actually save money
- Sell-to-cover at vesting. Sell enough shares the day the taxing point hits to cover a marginal-rate bill of up to 47%. Keep the rest for the upside.
- Check which scheme you’re actually in. Your ESS statement names the category — many “options” holders assume deferral when the plan is taxed-upfront.
- Use the 30-day rule deliberately. A late-June taxing point plus a July sale shifts the income to the next year — useful if your rate will be lower.
- Salary-sacrifice up to $5,000 a year of pre-tax salary into employer shares under a deferral arrangement — one of the few clean before-tax routes.
- Keep ESS statements forever. Your sale cost base a decade later starts with the statement from the taxing point year.
FAQ
I haven’t sold anything — why do I owe ESS tax?
The discount is income-taxed at the deferred taxing point (or at grant for upfront schemes) on the market value at that time — sale or no sale. Priya’s example: $55,000 of income, ~$25,850 of tax, zero proceeds.
I quit my job — does that trigger ESS tax on my options?
No — not since 1 July 2022, when it was removed as a deferred taxing point. You can still forfeit unvested interests under the plan rules, but there’s no tax trigger.
When does my 12-month CGT discount clock start?
Deferral schemes: the clock restarts at the deferred taxing point. Start-up concession: from the date the right was acquired — exercise doesn’t restart it. Taxed-upfront: from acquisition. See our CGT vs income tax explainer for the income/CGT boundary.
My options were issued at market price — how can there be a discount?
The option has its own market value. Pay nothing for an option worth $2,000 and the $2,000 is the Div 83A discount. Get a valuation or use the ATO safe-harbour method for unlisted rights.
Why isn’t my start-up ESS showing in myTax pre-fill?
Start-up concession discounts are excluded from income, so they’re never on ESS statements and never pre-fill. Only upfront and deferral-scheme discounts appear — the absence is correct.
Can I salary-sacrifice into an ESS?
Yes — up to $5,000 of pre-tax salary per year for employer shares under a tax-deferred arrangement. It’s distinct from the $1,000 upfront reduction; get advice before stacking them.
The bottom line
ESS tax is two taxes wearing one name: income tax on the discount — at grant, at a deferred taxing point, or never under the start-up concession — then CGT on everything after. The expensive mistakes come from mixing up which clock you’re on: the $180,000 income test, the 15-year ceiling, the 30-day sale window, and the re-acquisition reset. Nail the scheme type first — everything else follows.
