We are based in Allahabad. We have sold scrap material in Non-2011 and April-2012 to party based on Nagpur (Maharastra) and invoiced Sales with CST 5%. The CST collected is also deposited with sales tax authority and submitted the VAT return accordingly. The VAT Return for the financial year 2011-12 has already been submitted.
Now, the party has submitted Form-C and claim the refund of differentail CST 3%.
Is it possible to refund differentail CST3% to party for the sales invoiced in November-2011 and April-2012 and revise the VAT return of the respective period? Can this be made without revising the original 'TAX INVOICE' issued to the party at the time of sale?
Please advise.
