Hi Srinidhi,
     I'll add my extra points here.
   
     As Biju said u can create the professional tax groups by selecting the states, there you can define the slab. And you can assign this PT group to the "professional tax" Salary head when creating the salary group.
   
     Also regarding the PT reports, you can find all the government forms such as PT Form 9A, Form 5, Form 5A, etc.

Regards,
Natraj
