I am an alien resident now on F1 visa status. In summer of 2008, I worked as an intern in a out of state company and received about $7800 payment. I have just graduated in Dec 2008 and now on OPT status and will have internship in the same state that I previously interned.
The internship company did not withhold any tax, and I have not filed tax for the internship income in 2008 summer yet. I plan to do so but have no idea what tax form should I use, how much I should pay and how to file tax. I would be highly appreciated if someone can help me figure this out.

My questions again:
1) what Tax Form should I use?
2) how much tax should I pay?
3) what kind of tax should I pay?
4) how can I file tax? On line or in other way?
5) Is the tax for OPT period different from CPT period?

Thanks so much for your help!

1. If you did not complete 5 years on F1/OPT you will file non-resident tax return.
2 & 3. If you are non-resident as pre 1. then your income is not subject to FICA or SE taxes. You will pay income taxes.
4. File depending upon your resident status.
6. No.

Hey MukatA, thanks so much for your help!

However, there are some terms that I don't understand. What is "pre 1" and "FICA"?
Also, what is the tax rate for income taxes in my situation? I am not a U.S. citizen and I have been in the U.S. for less than 2 years.
Also, which tax form should I use? 1099? Or 1042?

Thanks a million!

Your tax rate depends on the amount of income your earned. More than likely, it will be either 10% or 15%.

You will use Form 1040NR or 1040NR-EZ, plus whatever state tax forms apply for your internship state.

Thanks for your answers:)
My company has me as an independent contractor, not employee. If that is the case, what % do I need to pay?Appreciated!

You are an F-1 student, so you are NOT liable for self-employment taxes.

You will need to file Form 1040NR with a Schedule C.

More than likely, you will pay between 10 - 15%.

Sure, very helpful:) hahaha~~~

One more question, what or how much deduction is applicable for me then?

Whole BOOKS have been written on the available deductions on the Schedule C. There is no way I can adequately cover it on this forum.

Read the instructions for Schedule C to get some idea what you can claim. If it seems a bit too confusing, then get professional tax help!
