This Friday, i.e. 1st September, 2017 CBEC has issued a circular and clarified that the errors made by tax payers in GSTR-3B can be rectified while filing regular returns in GSTR-1 & GSTR-2 respectively.
Previously, there was no provision to revise GSTR-3B even in case there was an inadvertent mistake in filing original GSTR-3B.
It's a positive move by the Government and a big relief for the tax payers who had filed GSTR-3B with errors.
