Karnataka input vat credit

Sir,

In the month of October, there is a typographical error of Rs.30/- in purchae basic value  resulting in a difference of tax payable of Rs.3/-.

Now, we want to know , since the amount is very small amount, is there any provision so that we can pay the vat amount along with nov. tax payable amount. Or we have to pay it separately.

Please reply

with regards

mala
