Frequently asked questions

What is GSTR-3B?

GSTR-3B is the monthly self-assessed summary return where the taxpayer declares GST liability, input tax credit claimed and net tax payable. It must be filed and tax paid by the 20th of the following month.

What is the late fee for missing a GST return?

What is GSTR-2B and why does it matter?

Contact us to know the exact pricing for your requirement. ITC can only be claimed if reflected in GSTR-2B — making supplier reconciliation essential before filing.
