Wrong invoice taken in Gstr-3b

This discussion addresses errors in GSTR-3B filing, specifically when a February 2020 invoice was incorrectly included in the January 2020 return, and a January 2020 invoice was missed. The advice given is that if the tax for the February invoice was paid correctly in January, no further action is needed. The missed January invoice can be declared in the February return, with interest payable on the January tax liability, though recent notifications may offer interest waivers under certain conditions. Taxpayers are advised to check these notifications for specific interest rates and waivers.
