According to your state VAT requirement, if you have crossed the basic limit, you must apply for VAT number. e.g. If you are from Gujarat and if you have crossed a turnover limit of Rs. 500000, you better apply for VAT as you are compulsorily required to obtain the VAT number. If you have not crossed, you better wait now and apply for GST number later.
