Last year I was a resident alien for tax purpose due to the presence test, and I worked for two employers, and received W-2 from employer A and 1099MISC from employer B. Both show zero for Social Security and Medicare taxes, maybe because I was holding F1 visa which confused my employers' HR.
For 1099MISC from employer B, I filled out Schedule C, which further asked me to filled out Schedule SE "Self-Employment Tax" to figure out the part of my Social Security and Medicare taxes from the employment.
For W-2 from employer A, shall I pay social security and medicare taxes, and how? 1040 doesn't seem to calculate them for me, does it?
