We have sold Iron Scrap material to the party charging the VAT @ 5% (VAT @ 4% Plus Addtional VAT @1%) throughout the financial year 2011-12 and till June-2012 and submitted the VAT return for respective period accordingly.
Now, it has been noticed that Additional VAT@ 1% is not applicable to Iron Scrap being the Goods of special importance in inter-State trade or commerce as per section 14 of CST Act..
Is it poosible to revise the return for financial year 2011-12 and monthly return for the period of April, May and Jun-2012 to provide the refund of additional VAT @1% to the party however refund has not been claimed by the party?
Whether this can be done without revising the original 'Tax Invoices' issued at the time of Sale.
Please advise.
