As per your concern let me tell you that for every property there is 2 different kind of tax, one is leived by local municipality and the other is leived by the concerned BLLRO department, i.e. known as KHAJNA,. And you have to give both of them here it keep it in mind that the property tax collected by municipality and land tax collected by West Bengal government...as khajna. and you have to deposit separate way as the collecting authorities are different.
