On $37K, and assuming you get married and file jointly, your tax liability will be about $2,300.

Dear tax expert,
Thanks for your reply. But, my earlier query also included knowing about taxes, when being single.

I earlier described myself being single, from India, visiting to work as a post-doctoral associate (research), in a US university (non-profit organization).The designation is of 'employee' status in the university, not as a 'student'. I am paid 37K per annum plus for my medicare. How much I may have to pay as my taxes annually, when I go with H1-B visa to USA?
Regards,
Suresh

For a single with no dependents, your income tax liability will be $3,936.
