🇺🇸 United States — 🇦🇺 Australia

Tax Treaty / Double Tax Avoidance Agreement detail

The US-Australia Income Tax Convention was signed on 6 August 1982 and entered into force on 31 October 1983, with a protocol signed in 2001 that introduced a number of amendments including a Limitation on Benefits provision. It is the primary instrument governing cross-border income between two major English-speaking common-law economies. Dividend withholding is reduced to 5% for companies owning at least 10% of the voting power in the paying company, and 15% for all other dividends. Interest payments face 10% withholding, which is higher than in many more recent US treaties; this remains a point of contention for cross-border debt financing. Royalties are taxed at a reduced 5% rate rather than the Australian domestic withholding rate of 30%. The 2001 protocol added a Limitation on Benefits article, though it is considered less comprehensive than LOB provisions in newer treaties. It focuses primarily on preventing conduit arrangements and requires qualified person status for access to treaty benefits. Australia's Goods and Services Tax (GST) and state-level payroll taxes are not covered by the income tax convention. Australia's dividend imputation (franking credit) system interacts with the treaty in complex ways. Fully franked dividends paid to US shareholders may effectively carry no additional withholding burden since the underlying corporate tax has already been paid, but unfranked dividends face the full treaty rate. A Totalization Agreement between the two countries prevents dual social security contributions and co-ordinates access to Australian superannuation guarantee and US Social Security benefits for cross-border workers.
