Dear All,

Pls help me, my company is filing monthly vat return, excess input vat at the end of the month c/f to next month and if payble comes in any month, it paid during the due date.

my Question is, in the month of july 2008 return, i have wrongly entered one sales invoice two times and filed the return accordingly for example invoice no 10, assessable value 10000/- so vat is rs.400, i have entered invoice no 10 two times & paid vat Rs,800/-,

now i have filed the vat return upto nov2008, now i found this mistake, what i have to do, all months return to be revise since july 2008 , or only july 2008 return to be revise and the excess of input tax to be adjust in dec2008 return.

pls help me

thanks a lot
