Is cst registration needed below 5lakh turnover business

sirs,

even thoug it is not compulsory, u cannot bill at the concession rate of 2%% for any intestaste transactions, and if u are a unregistered dealer u will not charge the tax in your bill and and the buyer has to pay at a higher rate of applicable vat in the state and cannot avail the benefit of reduced rate of 2% hnce it it advisable if ur transaction is interstate and better to have cst registration and file regular returns even it is nil.please

with regards
