Australian residents with US RSUs
ATO taxes vest at marginal rate (up to 47% with Medicare). 50% CGT discount on holdings >12 months — the major Australian incentive. US-Australia DTC reduces dividend WHT to 15%. Super wrapper for tax-efficient long-term US stock exposure.
Executive summary
Australia's RSU tax regime is governed by Division 83A of the Income Tax Assessment Act 1997. At vest, the FMV of vested shares is included in assessable income at your marginal rate — up to 45% federal income tax plus 2% Medicare levy, total 47% for high earners. The cost base for future CGT computation equals the FMV at vest in AUD using the rate on vest date. Your Australian employer reports vest income via Single Touch Payroll, so it appears pre-filled in your ATO return.
The most consequential mechanic for Australian RSU holders is the 50% CGT discount. Hold US RSU shares for more than 12 months after vest, and the capital gain on disposal is halved before being included in assessable income. For a top-bracket Australian, this drops the effective long-term CGT rate from 47% to 23.5% — among the most favourable LTCG rates in the developed world for high earners. The 12-month clock starts at vest, not grant.
US dividend WHT is reduced to 15% under Article 10 of the US-Australia Double Taxation Convention (with W-8BEN filed). The 15% is creditable against Australian income tax on the same dividend via the Foreign Income Tax Offset (FITO) on your ATO return. For US dividends held outside super, the net effective Australian tax rate is max(Australian marginal rate, 15%).
Super (superannuation) wrappers offer the strongest long-term US stock exposure tax-efficiency: 15% contributions tax on concessional contributions (up to AUD 30K/year), 15% tax on internal growth (with effective 10% on LTCG via 33.3% discount), and 0% in pension phase. For high-comp RSU holders, sweeping after-tax RSU proceeds into super via non-concessional contributions (up to AUD 120K/year) builds long-term US stock exposure in a far better tax environment than personal holding.

What happens at vest
Step-by-step walkthrough of the Australia mechanics when your US RSUs vest.
- 1
Vest value = FMV × shares at vest date
USD value, converted to AUD at the rate on vest date. ATO accepts RBA daily reference rate or actual exchange rate.
- 2
AUD value included in assessable income (Section 83A-10)
Treated as employment income, taxed at your marginal rate when added to salary + bonus.
- 3
Australian employer reports via Single Touch Payroll
Vest income is reported electronically to ATO, appearing pre-filled in your tax return.
- 4
Tax withheld at marginal rate
Combined federal income tax + 2% Medicare levy, up to 47% for high earners. Note Australia's brackets have a 37% rate from AUD 135K-190K and 45% above.
- 5
Net shares delivered to US broker account
If sell-to-cover applied, fewer shares delivered. Cost base for future CGT = FMV at vest in AUD.
- 6
12-month CGT discount clock starts
Vest date + 1 day onwards. Selling more than 12 months from vest unlocks the 50% discount. Document the acquisition date carefully.
- 7
US dividends face 15% US WHT with W-8BEN
Treaty rate under Article 10 US-AU DTC. Australian tax also applies to gross dividend with FITO claimed for the 15% US WHT.

Common mistakes (and what they cost)
The errors Australia RSU holders make most often.
Counting grant-to-vest as part of 12-month CGT clock
The 12-month CGT discount clock starts at VEST, not grant. Selling 11 months from vest doesn't qualify, regardless of when the original grant happened.
Cost: Loss of 50% discount = doubles effective CGT on that disposal
Wrong AUD/USD conversion rate for cost base
Cost base = FMV at vest × AUD/USD on vest date. Using sale-date AUD/USD for vest-date computation inflates or deflates gain. Document conversion rates per parcel.
Cost: Variable; can be material in AUD-volatile years
Holding too long past concentration thresholds for the discount
The 50% discount is a tax bonus, not an investment thesis. If a tech stock drops 30% during the holding period, the lost capital exceeds the tax saving.
Cost: Material — depends on stock action
Forgetting Foreign Income Tax Offset (FITO) on US dividends
The 15% US WHT on dividends is creditable against Australian tax via FITO. Not claiming it doubles up the tax. Reported on your ATO return.
Cost: 15% of dividends = permanent leak if not claimed
Missing super contribution timing for tax efficiency
Concessional contributions (AUD 30K/year) reduce taxable income by 32-47% top rate vs 15% super tax. Failing to use the cap leaves money in the higher-tax personal environment.
Cost: 17-32 percentage points on AUD 30K/year

Frequently asked questions
How does the 50% CGT discount work in Australia?
Hold US RSU shares for more than 12 months after vest, and your capital gain is reduced by 50% before being included in assessable income. Example: $20,000 gain × 50% discount × 47% marginal rate = $4,700 tax, vs $9,400 without discount. The discount makes 12-month holding nearly universal practice for Australian RSU holders.
What's the Australian tax year for filing?
1 July to 30 June (financial year). Tax returns due 31 October following year for self-filing; later with registered tax agent. RSU vest income reported via Single Touch Payroll by Australian employer, captures in pre-filled return.
When does the 12-month CGT discount clock start?
At VEST, not grant. The CGT acquisition date for Australian-resident RSU holders is the vest date. Selling >12 months after vest qualifies for the 50% discount. Selling at month 11 does not, regardless of when the original RSU was granted.
How does FITO work for US dividend WHT?
Foreign Income Tax Offset (FITO) lets you claim a credit on your Australian return for foreign tax paid on the same income. For US dividends, 15% US WHT is credited against your Australian income tax on the dividend. Net effective: max(Australian marginal rate, 15%).
Is super wrapping worth it for US stock exposure?
Yes for long-horizon money. Super internal tax rate of 15% (with 33.3% discount on LTCG = effective ~10% on long-term gains) vs personal 23.5% (with 50% discount) or 47% (without). In pension phase, super CGT is 0%. Lock-up until preservation age (60) is the trade-off.
What's ESS Division 83A and how does it apply?
Division 83A of the Income Tax Assessment Act 1997 governs Employee Share Scheme taxation. For most established-company RSUs, vest triggers Section 83A-10 inclusion of FMV in assessable income at marginal rate. Startup deferral (Subdivision C) requires employer eligibility — most US-listed companies don't qualify.
Can I lower my marginal rate via salary sacrifice into super?
Yes, partially. Salary-sacrifice into super (up to concessional cap of AUD 30K/year) reduces taxable income at marginal rate (32-47%) and is taxed at 15% inside super. Net saving 17-32 percentage points on the sacrificed amount. Plan around RSU vest timing for maximum effect.
