我已经是R了，TA收入学校一直没有扣SS和Medicare，已经两年了。我不主动补交有什么坏处吗？盼望能永久赖掉这两年的税。

总的来说就是收入和你的学位相关的，不用交，你的不是TA收入么？前面总结有提到的啊。

下午拖拉机？

前面总结is about nonresident.

I double checked at IRS web site. It looks like a grey area. My TA income could be taxible to nontaxible.

My school started to deduct my friend's SS tax once she got GC

your friend is a full time student and earns money assocated with her/his program?

I am not sure how to define the association with her program. TA appointment is a part of the PHD program. Also teaching as an instructor is a training, although we don't have to teach independently every semester.  The state pays us TA stipends

even for us citizen, a full time students engaging in on campus employment is exempt from ssn/medi.

不好意思，再问一下 （英语不是很好，没有看明白阿。）

f2来美，转 f1.〉　5年，填 1040 算resident alian.

cpt期间需不需要交FiCA？

full time student 是不是可以不用交？

那cpt算full-time student吗？　要不要交ｆｉｃａ？

如果，　我说如果误交了，　怎么像ｅｍｐｌｏｙｅｅ提出来？已经交的怎么拿回来？

不需要８４３填表吧？

谢谢啦　

I have read all the replies. Still not quite sure what I should do. My visa changed from F1(OPT) to H1B on Octobor 1, 2007. my employer never deduct anything for medicare and social security taxes from my pay. I just noticed that from my W2 form. So now my question is how do I pay IRS? How do I figure out how much i owe IRS? HR in my firm refused to do anything for me. Btw, I have already filed the tax extension form but I didn't take into account the social security and medicare taxes I owe.  Please help! Urgent!

for SSN, every $1050 you made and paid SSN tax, you will earn a credit. each year it's upto 4 credits. To get SSN money once you retired, you have to earn 40 credits. Roughly, how much you can get is based on how much you paid on SSN tax, how many credits you earn then divide by 35 years and 4 credits/year.

so basically, less you paid on SSN tax, less you gonna get from SSN once you are tired. If possible, try to pay SSN tax as early as possible, so you can start to earn credits earlier.
