I'm a resident alien under tax treaty, so I have both W2 (with an income in box 1) and 1042S (with another income). How can I state this and the tax treaty in my taxes?

I've stated the W2 income as turbotax requested. Then I've added the 1042-S income as other income, and the W2 income + 1042-S income with a negative sign (to take into account the tax treaty) as another income. However, turbotax is saying that my total income is $0. What number should I put as negative income to take into account the tax treaty? Where can I find it?

The 1042S covers a variety of forms. United States Income Tax Treaties vary between countries and what is taxable versus what can be removed. There is also taxable income with a foreign tax credit.

Adding the w2 is straightforward. The 1042-S should be added as the type of income it is, but, sometimes other income is the only option. Removing income from the treaty as a negative is correct.

Since you removed all of your w2 and 1042S income that would leave zero taxable. I have never seen w2 wages subtracted before so be sure you are actually entitled to subtract those wages.

Double check the treaty with your country from United States Income Tax Treaties to verify what is taxable and what is not.
