The
United States – France Tax Treaty covers double taxation with regards to different types of income tax and capital gains tax, however, as already mentioned, the benefits are limited for American expats living in France. The treaty does ensure though that no one will pay more tax than the higher of the two countries’ tax rates, and it also defines where taxes should be paid, which normally depends on where the income arises.
There may still be benefits in the US-France Tax Treaty for American researchers, teachers, students, diplomats, and professional athletes competing. To claim a provision in the United States – France Tax Treaty (besides claiming US tax credits), expats can use
IRS Form 8833. The way for most US expats to avoid double taxation on their income arising in France is to claim US tax credits to the same value as French income taxes that they’ve already paid. For income arising in the US,
Americans in France can claim French tax credits against income US taxes paid to the IRS.The
US-France Tax Treaty also contains a clause that allows the French government to send US expats’ French tax information directly to the IRS, as well as their French bank and investment account balances.
