Declaring Australian working-holiday income back in France

Updated 2026-06-16

If you remain a French tax resident during your working holiday (which is common, especially for shorter trips), France expects you to declare your worldwide income, including your Australian wages, on your French return. People skip this because they assume "I already paid tax in Australia". That's a mistake of category: the France-Australia tax treaty stops you being taxed twice, but it does not remove the duty to declare.

In practice the treaty's mechanism (a credit equal to the French tax on that income) usually means you don't pay French tax twice on it, but the foreign income still has to appear on the return so the calculation is correct. If your situation is borderline (long trip, ties cut with France), get specific advice, residency can flip.

This is general information, not personalised tax advice, and it concerns your French obligations. For a complex year, a French tax professional is worth the fee.
