If you've made a mistake in your GSTR 3B filing, particularly by overstating the taxable value in table 3.1(a), you can adjust this in subsequent returns. If the tax amount paid was correct, declare the correct tax amount and a nil turnover for the current period, adjusting the excess turnover over the following months or even into the next financial year until it's fully reconciled. Ensure your GSTR 1 filings accurately reflect the actual turnover for all months.

Adjust the excess turnover in the next month GSTR 3B. If the turnover is greater than the full year Turnover then adjust the same till next FY. However if the tax amount was correct then only put tax amount in the next month GSTR 3B and turnover as Nil. Further while filing GSTR 1 give the actual turnover in all the months.
