Professional tax of partnership firm in west bengal

I recently formed a partnership firm with my wife in the Financial Year 2016-17 in the state West Bengal, but there was no turnover in that year moreover till date I have not one any activity in the partnership firm. Kindly tell whether the Partnership firm is liable to pay the professional tax? My another question is do partners is also liable to pay the professional tax even if the partnership firm becomes liable to pay the professional tax in west bengal?
