US-Australia Tax Relationship

The US-Australia Tax Treaty (amended 2001) provides for reduced withholding on dividends (15%), interest (10%), and royalties (5%). Special provisions exist for superannuation and pension plans.

Key Tax Considerations for Australia

Superannuation Complexity

Australian super is not recognized as a qualified pension by the IRS. Annual contributions and earnings may be taxable.

PFIC Nightmare

Most Australian managed funds are PFICs. Punitive US tax rates apply unless you make QEF or mark-to-market elections.

High Tax = Good FTC

Australia's relatively high tax rates often generate excess foreign tax credits to offset other US income.

Different Financial Year

Australia uses July 1 - June 30 fiscal year, requiring careful income allocation for US calendar year reporting.

Common Expat Scenarios

American Professional in Sydney

Earning AUD salary, employer contributing to superannuation, invested in Australian index funds.

Our Approach: FTC typically better than FEIE due to high AU tax rates. Super contributions taxable in US. Avoid managed funds (PFIC) - use US-listed ETFs.

Dual Citizen Running Business

Australian-American operating business in Melbourne, has retirement savings in both countries.

Our Approach: Complex filing with business income, potential Section 962 election, coordinate super with US retirement planning.

American Retiree on Visa

Retired to Australia, receiving US Social Security and pension, opened Australian bank accounts.

Our Approach: Treaty determines SS taxation, report AU accounts on FBAR, consider health insurance implications.

Frequently Asked Questions

Is my Australian superannuation taxable in the US?
This is complex and contested. The IRS has not provided clear guidance. Conservative view: employer contributions and earnings are taxable annually. Some practitioners take position that super is a tax-deferred account. We recommend proper disclosure and consistent treatment.
Why are Australian managed funds a problem?
Most Australian managed funds (unit trusts, managed investments) are classified as PFICs (Passive Foreign Investment Companies) by the IRS. This triggers punitive tax rates up to 50%+ on gains unless you make annual QEF or mark-to-market elections. Each fund requires separate Form 8621.
Should I use FEIE or FTC in Australia?
Due to Australia's high tax rates (top rate 45% + levies), Foreign Tax Credit often provides better results than FEIE. FTC can offset US tax on up to the full amount of Australian-source income, while FEIE caps at $134,000. We model both scenarios for clients.
How do I handle the different fiscal years?
Australia's financial year is July 1 - June 30. You'll need to allocate income to the US calendar year. Use payslips for salary timing. Australian tax returns (due Oct 31) won't match your US return periods exactly.
