Karnataka Professional Tax - Enrollment

In the case of Limited Liability Partnerships (Karnataka Jurisdiction).

What is the PT Enrollment Fee? Is it Rs.2500?

or

Is it based on the number of partners? per partners, the fee is applicable (i.e Rs.1000 per partner somewhere I read)..?

In case, PT EC fee is based on partners, One partner is salaried and PT is already deducting from his salary, then he needs to pay PT again?

Kindly clarify.

Thank you
