Suggest How much I have to pay as Income Tax?

you stated your gross income.....you had expenses involved right?.....your tax would be on your adjusted gross income...that is your net.......also....are you filing a us federal return?....if so your return will require different procedure.....are you a non resident of india? part-time resident?....was your income subject to us federal withholding at any time?.....unfortunatley there are too many variables involved.....if you were a us resident and earned your money here and it is subject to income tax you can expect to pay out anywhere from 30%-40%
