Tds & pt (professional tax)

Hello sir,

If some one got salary 50000 per month and he is Salaried person.

so, there 50,000 X 12 = 6,00,000/- In that case 

tax nill on 2,50,000 remainning 3.50,000/-  we deduct @ 5% tds which is Rs.17,500/-

In monthly case, if we pay 50000/- that person that means we deduct 1458 tds. am I right or wrong.

after that how much amount deduct for PT (professional tax)

please suggest anyone.

Regards,

Ram
