Regarding GSTR9 and GSTR9C Wrongly filed

If you've filed your GSTR9 or GSTR9C incorrectly, there's currently no direct way to revise these returns. The advice suggests explaining any discrepancies to the GST department when queried. If the error has resulted in an additional tax liability, it's recommended to pay it. Otherwise, you may need to ignore the error. Visiting your local GST department office for a discussion is also an option.
