FAQ

Frequently Asked Questions

How much tax will I pay in USA vs Australia at $100,000?

At $100,000: USA federal tax is roughly $14,000, plus state tax (0% in Texas, $9,300 in California). Australia charges about $22,000 including the 2% Medicare levy. So USA wins in no-tax states, but loses in high-tax states like California where total reaches $23,300.

Do US citizens pay taxes when living in Australia?

Yes—US citizens must file Form 1040 reporting worldwide income regardless of where they live. The Foreign Tax Credit usually eliminates US liability since Australian rates are higher. The FEIE can exclude up to $130,000+ of earned income. You'll file both Australian and US returns annually.

What's the real difference including healthcare?

Australia's 2% Medicare levy covers universal healthcare. In the USA, employer health insurance averages $6,000-$12,000/year employee cost. Add this to the tax comparison: a $100,000 Californian might pay $23,300 taxes + $8,000 healthcare = $31,300 total, vs Australia's $22,000 all-inclusive.

Does Australia have state income tax?

No—Australia abolished state income taxes in 1942 and never brought them back. This is the biggest advantage over the USA: Sydney and Melbourne have 0% state tax. Compare to California (13.3%), New York City (12.7%), or New Jersey (10.75%). For high earners, this alone can mean $15,000+ annual savings.

What's Australian Superannuation and why does it matter?

Super is mandatory employer retirement contributions—currently 11.5% of salary, rising to 12% by 2025. Unlike US 401(k) which is optional and averages 3-6% match, every Australian employee automatically builds significant retirement savings. On a $100,000 salary, that's $11,500/year your employer pays into your retirement.
