Deductions & credits

Yes thank you, after some further research. I declared my spouse’s income as additional regular income in TurboTax, which gets income taxed like everything else. Because there is a treaty with France, I put in a foreign tax credit for the taxes he is already paying in France so that there’s no double taxation. So at the end he is paying all the taxes like any US citizens/green card holders, except just not double taxed in both countries
