Hi everyone,

I have some questions about my F1-OPT tax. I know that from the IRS website, I am exempt from Social Security and Medicare tax with the less than 5 years rule. But I know I am subject to Federal and State Taxes.

My questions are the followings:

1. How much Federal Income Tax that I am subject to pay and how much for Witholding. I do not understand what rate or amount for the Federal Witholding that I am subject to. Is it base on my monthly gross income or annual gross income. Is it different from state to state. Where can I get the information from the IRS website or from other sources.

2. Do I subject to other taxes beside the Federal and States Taxes for my employment.

3. Is it I need to file Form 1040 NR and Form 8843 assume I file single, standard deduction with no other personal allowances. What other forms I also need to file.

4. If I need to file resident aliens later because of more than 5 years, how much Social Security and Medicare tax that I am subject to. Where can I get the rates and amouts information from the IRS website and other sources.


Thank you so so much for your time for reading and answering my questions.
Thanks.
