Yes you must pay taxes on your earnings.  Yes, why would you not be able to put it on your resume.  Most importantly is that you should make sure that what you are doing for this company is legal.  Because the company is based in India it will be very difficult and expensive to pursue any legal claims against them if something wrong were to occur.  If you are doing something against the law you will get in trouble.  Also, if the company does not pay you, it will cost more to get them to pay you then you probably will get paid.  There is always risk in working with a company outside of the United States.  Make sure you investigate this company to ensure they are legitamate and obeying U.S. Laws.  If anything goes wrong most likely you will be responsible because the company will be difficult to hold to U.S. jurisdiction.  Just because you do not know that something is illegal is not an excuse. You will be held accountable for any misconduct arising from your job.   Make sure what you are doing is legal.  If you want me to research the legality of your activities I will need to know specifically what it is you are doing for this India company.  Beware. Ignorance is not a legitimate excuse to breaking the law. Best Regards, Codi M. Dada, Attorney at  Law.
