Work out your ESS tax under Division 83A — taxed-upfront, deferral and start-up concession compared side by side, with the $1,000 reduction, 30-day rule and CGT on later disposal.
3 regimes comparedDivision 83A
01 —INPUTS
ESS details
Salary before the ESS discount — drives your marginal rate.
Often $0 for free shares; exercise price for options.
$1,000 reduction (s 83A-35)
Taxable income + reportable fringe benefits + reportable super + net investment losses. Must be ≤ $180,000 for the reduction to apply.
Later disposal (optional — for CGT)
For start-up shares the 12-month CGT clock runs from grant, not the taxing point.

Things to check
Adjusted income is under $180,000 but scheme must also be non-discriminatory (offered to ≥75% of permanent staff with ≥3 years service) to claim the $1,000 reduction.
Rule reminder — cessation of employment
Ceasing employment is no longer a deferred taxing point for ESS interests from 1 July 2022. Many online calculators and older advice still include it — this calculator does not.
The current deferred taxing points are: (a) no real risk of forfeiture AND no disposal restrictions (for options: also after exercise), and (c) 15 years after grant.

The start-up concession is only available where the employer meets s 83A-33 eligibility (unlisted, aggregated turnover < $50M, incorporated < 10 years, Australian-resident, employee ≤ 10% equity/voting, 3-year holding).
→Taxed-upfront: At grant — discount less up to $1,000 if s 83A-35 applies. Label 12D (with reduction) or 12E (without).
→Deferral (s 83A-105): At deferred taxing point — discount at MV on that date (or disposal price if sold within 30 days). Label 12F.
→Start-up concession: No ESS tax — CGT only on sale. $0 at grant; CGT on gain over amount paid.
$1,000 reduction — the two gates
The upfront-scheme $1,000 reduction under s 83A-35 requires both of the following:
→Non-discriminatory scheme: Offered to at least 75% of permanent employees with 3+ years of service on a non-discriminatory basis
→Adjusted taxable income ≤ $180,000: Taxable income + reportable fringe benefits + reportable employer super contributions + total net investment loss + deductible personal super contributions
At marginal rates of 37% or 45% the reduction is worth $370 or $450 — real money, but only if you qualify on both gates. A scheme offered only to executives does not meet the non-discrimination test, regardless of income.
Deferred taxing point
Under the post-1-July-2022 rules, the deferred taxing point is the earliest of:
→No forfeiture risk + no restrictions: The interest is no longer at real risk of forfeiture AND there are no genuine disposal restrictions. For options or rights, this only applies after they have been exercised.
→15 years after acquisition: Was 7 years for interests acquired before 1 July 2015.
Cessation of employment is no longer a deferred taxing point for ESS interests where cessation occurs on or after 1 July 2022. This is one of the most common pieces of stale advice circulating on forums — many older calculators and blog posts still include it.
The 30-day rule in practice
Sections 83A-115(3) (shares) and 83A-120(3) (rights/options) override the deferred taxing point if you dispose of the interest within 30 days after that date. Two consequences matter:
→Tax year can shift: If the would-be taxing point is 20 June and you sell on 2 July, the whole ESS income sits in the following financial year.
→No CGT event on the shares: The cost base resets to the same disposal price, making the capital gain effectively zero.
Start-up concession — the unique 12-month clock
→No ESS discount at grant: Zero income inclusion when you receive the interest.
→CGT cost base = amount paid: For shares; or market value at exercise for options.
→12-month clock runs from grant date: Not from a deemed taxing point — gives 50% CGT discount up to two years earlier than taxed-upfront path.
The quid pro quo: the scheme's design must be compliant. For shares the discount at grant can be no more than 15% of market value; for options the exercise price must be at least market value at grant. The employee must hold no more than 10% of the company by equity or voting power (including associates).
CGT on later disposal
Every ESS regime eventually interacts with CGT. Once the ESS taxing point has been reached, you are treated as having re-acquired the interest at its market value on that date — or at the disposal price if the 30-day rule overrode it. That value becomes your CGT cost base. Subsequent growth is a capital gain, eligible for the 50% discount if held more than 12 months from the taxing point (or from grant for start-up shares).
Employees granted RSUs by large US-listed employers in Australia most often land on the deferral path — shares are forfeited if you leave before vest, so they satisfy the "real risk of forfeiture" test. The deferred taxing point is typically the vest date. Once vested and the selling window opens, the 30-day rule becomes critical for anyone following a sell-to-cover strategy.
FAQ
What is an Employee Share Scheme (ESS) in Australia?
An ESS is a scheme where an employer grants an employee shares, options or rights in the company — often at a discount or for free. The discount (market value minus what you paid) is taxable under Division 83A of ITAA 1997. Depending on the scheme design, you're taxed at grant, at a deferred taxing point, or (for eligible start-ups) only when you sell.
What is the $1,000 reduction and when can I claim it?
Section 83A-35 lets employees in a taxed-upfront scheme reduce their ESS discount by up to $1,000 — but only if the scheme is non-discriminatory (offered to at least 75% of permanent employees with 3+ years service) AND your adjusted taxable income is $180,000 or less. Adjusted income means taxable income plus reportable fringe benefits, reportable employer super contributions, net investment losses, and deductible personal super contributions. The reduced amount goes at label 12D on your tax return instead of 12E.
Is cessation of employment still a deferred taxing point?
No — this was removed from 1 July 2022 by the Treasury Laws Amendment (Cost of Living Support and Other Measures) Act 2022. Many older guides and calculators still list it. The current deferred taxing points are (a) when there is no real risk of forfeiture and no genuine disposal restrictions — for options, only after they are exercised — and (b) 15 years after grant. Employees who left their employer on or after 1 July 2022 no longer trigger a taxing point simply by leaving.
What is the 30-day rule?
If you dispose of your ESS interest within 30 days after what would have been the deferred taxing point, s 83A-115(3) (shares) and s 83A-120(3) (rights/options) shift the taxing point to the disposal date. The assessable amount then becomes the market value at disposal — which, for an arm's length sale, equals the sale proceeds. A practical effect is zero CGT on the shares themselves, because the cost base resets to the same disposal price.
How does the start-up concession work?
If the employer is an unlisted Australian company with aggregated turnover under $50 million and is less than 10 years old, and you hold no more than 10% equity and voting rights, s 83A-33 lets you escape ESS tax at grant. Instead, CGT applies only when you sell. Crucially, the 12-month CGT discount clock for start-up shares runs from the grant date — not from a taxing point — which is a unique benefit not available under the regular taxed-upfront or deferral rules.
How does CGT work on later disposal?
After the ESS taxing point, you are treated as having re-acquired the interest at its market value on that date (or at the disposal price if the 30-day rule applied). This deemed re-acquisition becomes your CGT cost base. When you later sell, any gain over that cost base is a capital gain, and the 50% CGT discount applies if you held the interest for more than 12 months from the taxing point. Start-up shares are the exception: the 12-month clock runs from grant.
Which label on my tax return do I use?
Label 12D is for taxed-upfront ESS discounts that qualify for the $1,000 reduction. Label 12E is for taxed-upfront discounts that don't qualify. Label 12F is for deferral scheme amounts (including start-up disposals where an ESS amount is ever triggered). Your employer must issue an ESS statement by 14 July and lodge the ESS annual report to the ATO by 14 August — the statement is authoritative, ATO pre-fill data can lag.
