Mr. Arun, Your sales done before registration is assessable to tax, and therefore ,you can issue 'C' form for the purchases made earlier to registration. MJK

Mr. Arun, A Trader should register himself under VAT and CST laws as soon he does an interstate transaction.There is no minimum fixed for registartion.In fact, your supplier should ask for your TIN no before charging concessional rate of tax and quote the same in his invoice.Check posts also create problem when they get goods with an invoice without buyer's TIN no,and they levy penlty.The CST Act also specifies that sales can be made to a registered dealer of another state on submission of prescribed form issued by prescribed authority. However,if purchases are already done by you,within last three months back, you can cover it by issuing 'C'form obtained after registration also.Invoices issued in a particular FY can be combined without any limit in one 'C' form,but within 3 months.There are no pointed case deccisions by Courts.No rules and notifications tohelp you. As your sales prior and after registration are clubbed together in returns and assessments the issue of 'C'forms also can be combined for pre and post registration purchaases as a general practice.
