Australian residents with US RSUs: complete tax + filing guide for 2026

You're at Atlassian Sydney, Canva Surry Hills, Google Sydney, or a US bank's APAC desk in Melbourne. Your US RSUs vest. The Australian tax framework includes one materially favourable feature: the 50% CGT discount for >12-month holdings. This guide is the complete Australian framework for US RSU tax in 2026.

The 30-second answer: Australian residents pay marginal income tax (up to 47% including 2% Medicare Levy) on RSU vest. Cost basis = FMV at vest in AUD. Sale taxed via CGT, with 50% discount on holdings >12 months — effective LTCG rate ~23.5% for top bracket. US WHT on dividends: 15% with W-8BEN under US-Australia DTC Article 10 — creditable via Foreign Income Tax Offset (FITO). Report via ATO Tax Time annual return (Australian tax year 1 July - 30 June; return due 31 October).

The Australian tax framework — key features

For Australian-resident individuals with US RSUs:

1. Vest income — fully assessable at marginal rate
2. CGT on sale — 50% discount for >12-month holdings (the major incentive)
3. Dividend tax — at marginal rate with FITO credit for US WHT
4. Tax year — 1 July to 30 June
5. Tax return filing — annual, via myTax / ATO Online / registered tax agent
6. No separate foreign asset disclosure — but worldwide income reportable

Australian tax year and filing timeline

The Australian tax year (financial year) runs 1 July to 30 June — different from calendar year and US fiscal year.

Key dates:

• Tax year: 1 July to 30 June
• Self-filing deadline: 31 October
• With registered tax agent: typically until 15 May of following year (varies)
• PAYG withholding: throughout the year via employer

For 2025-26 Australian tax year (1 July 2025 - 30 June 2026), return due 31 October 2026.

The vest event — Australian mechanics

When your US RSUs vest while you're Australian resident:

1. Vest value = FMV × shares at vest date in USD
2. Convert to AUD at the prevailing exchange rate (ATO accepts spot or monthly average on vest date)
3. Vest income classified as ESS (Employee Share Scheme) income under Division 83A ITAA 1997
4. Taxing point: vest date (cessation time when shares no longer subject to forfeiture)
5. Australian employer reports via STP (Single Touch Payroll) to ATO
6. PAYG withholding may apply — but often doesn't perfectly match liability
7. Cost basis for CGT = FMV at vest in AUD

ESS (Employee Share Scheme) framework

Australia's ESS framework distinguishes between different equity comp types:

Tax-deferred ESS interests (most common for RSUs):

• Taxing point: when shares vest and forfeiture risk ends
• Could be at exercise/vest or at certain other deferred points
• For standard RSUs: vest date

Tax-upfront ESS interests:

• Taxed at grant
• Used for some specific structures, often with $1,000 reduction

For most Australian FAANG engineers receiving standard time-based RSUs, vest is the taxing point with full FMV included in assessable income.

Australian individual income tax rates (2025-26)

Taxable income	Tax on this income	Marginal rate
$0 - $18,200	Nil	0%
$18,201 - $45,000	16¢ for each $1 over $18,200	16%
$45,001 - $135,000	$4,288 + 30¢ for each $1 over $45,000	30%
$135,001 - $190,000	$31,288 + 37¢ for each $1 over $135,000	37%
Over $190,000	$51,638 + 45¢ for each $1 over $190,000	45%

Plus:

• Medicare Levy: 2% of taxable income (most residents)
• Medicare Levy Surcharge: up to 1.5% (for high earners without private health insurance)

Combined top marginal rate: 47% (45% income tax + 2% Medicare)

Implication for FAANG comp: for Sydney-based engineer earning AUD 400K base + AUD 400K RSU vest = ~AUD 800K total. Most income above $190K taxed at 47%. Material take-home difference vs Singapore (top 24%) or Dubai (0%).

The 50% CGT discount — Australia's signature tax benefit

For Australian-resident individuals (and trusts), capital gains on assets held more than 12 months are reduced by 50% before being included in assessable income.

Mechanics:

• Buy/vest date establishes acquisition date
• Hold >12 months → 50% discount applies
• Hold ≤12 months → no discount, full gain in assessable income

Example for top-bracket holder:

Holding period	Capital gain	Discount	Assessable	Tax at 47%
≤12 months	$50,000	0%	$50,000	$23,500
>12 months	$50,000	50%	$25,000	$11,750

The 12-month hold cuts tax in half. For Australian RSU holders, the 12-month hold strategy is essentially universal practice.

US dividend withholding for Australian residents

Under Article 10 of US-Australia DTC:

• Without W-8BEN: 30% default
• With W-8BEN: 15% reduced rate

Australian side:

• Gross dividend (USD × AUD/USD on payment date) reported as assessable foreign income
• Taxed at marginal rate (up to 47%)
• 15% US WHT creditable via Foreign Income Tax Offset (FITO)

Example: $100 USD dividend (gross), AUD 1.50 per USD:

• Gross AUD: $150
• US WHT (15%): $22.50
• Net received: $127.50
• Reported as assessable foreign income: $150
• Australian tax at 47%: $70.50
• FITO claim: $22.50
• Net Australian tax due: $48
• Total effective rate: 70.5/150 = 47% (the higher of Australian rate and treaty rate, which is Australian)

For lower-bracket holders, the FITO can offset more of the Australian liability.

Reporting on ATO tax return

Australian residents with US RSU activity must report:

Employment income from RSU vest

• Pre-filled from STP employer reporting (typically auto-fills)
• Verify amount matches your records
• Located on tax return: salary/wages section

Capital gains on sales

• Required if total gains exceed certain thresholds OR proceeds > $10,000
• Capital gains schedule
• Apply 50% discount if held >12 months
• Document acquisition date (vest date) and sale date

Foreign income (US dividends)

• Reported in Foreign income section
• Gross dividend in AUD with AUD/USD rate
• Claim FITO for US WHT paid

Foreign Investment Fund (FIF) — historical and largely abolished

• The old FIF rules (taxing accrued income from foreign mutual funds) were largely repealed
• Some attribution rules remain for controlled foreign companies but not retail RSU
• Most Australian RSU holders not affected

Super (Superannuation) — the Australian retirement wrapper

For long-term US stock exposure within Australia's tax framework:

• Concessional contributions (pre-tax): $30,000 annual cap (2024-25); taxed at 15% within super vs your marginal rate outside
• Non-concessional (post-tax): $120,000 annual cap; tax-free contribution; investment growth taxed at 15% within super
• Pension phase (post-retirement): potentially tax-free withdrawals
• Estate transfer: super doesn't form part of your estate (binding death benefit nominations)

Holding US stocks in Super (via SMSF or platform):

• Capital gains within super: 15% in accumulation phase; 0% in pension phase
• Dividend income within super: 15% in accumulation, 0% in pension
• US WHT still applies but creditable

Strategic implication: for long-term US stock exposure, Super (especially via SMSF — Self-Managed Super Fund) offers materially lower tax than personal holdings. Most Australian FAANG engineers don't fully utilize this until later career stages.

Cross-border vesting — moved to/from US

For Australian residents whose RSU vesting period included US workdays:

Article 14 (Independent Personal Services) of US-Australia DTC: uses workday attribution

Example: 4-year vesting starting January 2022. You worked 2 years in US (2022-2024), then moved to Australia in January 2024. Vest in February 2025:

• 2/3 of vest income = US-source (2 of 3 years worked)
• 1/3 of vest income = Australian-source
• US WHT may apply to US-source portion
• Australian tax applies to all (worldwide income basis); FITO credits US tax

For complex cross-border situations, get specialist advice — ATO and IRS positions may differ on specific facts.

Strategic playbook for Australian RSU holders

1. Sell-at-vest discipline for diversification — convert to AUD, reinvest in broad-market ETFs (VAS, VGS, etc.)
2. For holdings, target >12 months — 50% CGT discount is the major lever
3. Maximize Super contributions — concessional contributions within cap reduce marginal tax + grow tax-efficiently
4. Consider SMSF for sophisticated investors — more control over US stock investments
5. Maintain W-8BEN — 15% US WHT instead of 30%
6. Claim FITO for US dividend WHT — don't pay tax twice
7. Time discretionary sales — push above-discount-threshold sales to year with lower marginal rate if possible
8. Use franking credits on Australian dividends — different mechanism but creates broader tax planning context

Common Australian RSU mistakes

1. Selling at month 11 instead of waiting for 12-month CGT discount — costs ~50% of CGT
2. Not claiming FITO for US dividend WHT
3. Misclassifying vest as "trust distribution" — vest is employment income, not trust income
4. Wrong AUD/USD rate — use rate on transaction date, document consistently
5. Holding too much employer stock — Australian employee + Australian-listed competitor + Australian super = overconcentration in Australia/AUD
6. Missing 31 October self-filing deadline — engage tax agent if complex

The closing read

Australian RSU holders face higher marginal tax rates than Singapore/UAE but benefit from the 50% CGT discount that materially reduces the effective long-term capital gains rate to ~23.5% for top bracket.

Three principles:

1. Sell-at-vest for diversification unless holding for >12 months with conviction
2. For holdings, target >12 months to unlock the 50% discount
3. Maximize Super for long-term tax-efficient US stock exposure
