Us citizen/resident hired for indian company.. tax rules?

Request help.. we are a software company in India. We are looking to hire a US citizen & resident to work for us from the US itself... he will be on the Indian company's payroll and we have been told that we can pay him his entire salary, with no deductions, and require him to pay his taxes in the US, per their prevailing IT rules.

Is this accurate? Can someone guide me towards some material that will help me with this?

Thanks
Sonia
