Professional Tax Being Deducted From Net Salary

Hello,
I have some doubt regarding Professional Tax.
I am working in a company which is registered in USA and I am working in Pune and I have an offer letter which has name Inc. not Pvt Ltd.
Even they don't deduct Professional Tax from my salary.
So, want to know is it fine or there is something wrong in that?
Would appreciate if anybody can help or answer this.
Regards,
Abhinav

Professional tax needs to be deducted from salary as per pay range.
Whether company is called inc or pvt ltd,PT will have to be deducted.
