Deductions & credits

hm, you seem right. I saw something like that on state return. I even saw the name of it "sticky tax rate".

I see the diff between tax bills 12% of the foreign income.

 

The income of my wife lowers then the limit by 10% - $19,750.

IE, what was taxed before adding foreign income by 10% after "pushing up" become taxed by 22%; ie 22% - 10% = 12% in addition.

And the sum of that is the same, as the sum of foreign income. That's why I was under the impression, that I was taxed on foreign income. But it was wrong.

Seems like I was taxed on US income "under higher tax bracket" but the sum was the same as foreign income.

Yes, it seems correct. Thx for that idea 🙂
