Tax percentages for F1 and H1B
Hello,
Here are my questions:
1) I was working from January 08 to July 08 (in Washingtong DC) part-time on campus on my F1 student Visa. The university took out both federal and state taxes from my paycheck. Can you please tell me what are the percentages for each of the state and federal tax? And when I file for returns next April, can you also please tell me how much I will get back from the taxes they took out of my paycheck?
2) In August 08, the university sponsored me for an H1B visa. And in my first pay check they took out 1.46 % for FICA medicare and 6.27% for FICA social security, 15.61 % for federal taxes, and 5.64% for State Taxes. Are these number accurate? Is there an official website that list what percentages H1B holders are supposed to pay for taxes?
3) How do I benefit from Social security and what is it used for, especially in my case where I am on an H1B visa?
4) When I file my taxes next April, am I expected to get any of the taxes of paid?
Thank you very much,
John
