🇦🇺 Australia — 🇬🇧 United Kingdom

Tax Treaty / Double Tax Avoidance Agreement detail

The current Australia–UK double tax convention was signed in Canberra on 21 August 2003, replacing the 1967 convention and its 1980 amending Protocol. It entered into force on 17 December 2003, with effect for withholding taxes from 1 July 2004 in both countries. The treaty reflects the long and deep economic relationship between the two countries: the UK is one of Australia's largest sources of foreign direct investment and the two nations share significant cross-border workforce mobility. Under Article 10, dividends are exempt from source-country withholding (0%) where the beneficial-owner company holds at least 80% of the voting power for a continuous 12-month period preceding the dividend declaration and meets applicable stock-exchange or ownership conditions; a 5% rate applies where the beneficial owner holds at least 10% of the voting power; and a 15% rate applies to all other (portfolio) dividends. Interest (Article 11) is capped at 10% of the gross amount at source, but a 0% rate applies to interest derived by governments, central banks, and unrelated financial institutions, making the effective rate very low for institutional flows. Royalties (Article 12) are capped at 5%, reduced from the 10% ceiling in the 1967 convention. A standard OECD-model tiebreaker applies for dual-resident individuals: permanent home, then centre of vital interests, then habitual abode, then nationality, then mutual agreement. The non-discrimination article (Article 23) protects nationals and enterprises of each state from discriminatory taxation in the other. Both Australia and the UK have signed and ratified the OECD Multilateral Instrument (MLI), and its provisions apply to this convention. A separate bilateral social security totalization agreement is in force, covering state pension entitlements and preventing double social-security contributions for cross-border workers. The treaty does not contain a US-style saving clause. The large Australian expatriate community in London and UK nationals on working-holiday or skilled visas in Australia make tax-residency tiebreaker determinations practically important, particularly given Australia's source-based dividend imputation system and the UK's residence-based regime.
