If filing status box is 3,4 or 5 and line 28 is not more than 80,450 then file 42,250 but I do have more than 80,450 on line 28. So, to figure out i will have to fill the worksheet. What should I fill on line 1 and line 3 of the work sheet?=======>on exemption/s for line 29 , you need to put $120,700 since you are single filer.
I should consider myself as married filing jointly or married filling separately. Note: I am married and wife doesn't have any income.==========> Generally, you cannot file as married filing jointly unless your spouse is a US resident/ citizen ; However, nonresident aliens married to U.S. citizens or residents can choose to be treated as U.S. residents and file joint returns.
