Taxes in two countries: what to know before you move
In France you declare your income in the spring of the next year. If you declare in France for the first time, it is a paper return (F36401); the step on your first return shows the date. US citizens: the US taxes its citizens wherever they live, so a US return stays due (IRS).
We do not give tax advice: a tax adviser who works with both countries can tell you how they fit together.
Each fact links to the official Service-Public page (in French). This is general information, not legal advice.
