GSTR-3B

Monthly summary return where GST liability is declared and payment made.

Full Definition

GSTR-3B is a monthly self-assessed summary return filed by all GST-registered persons. It summarises: total outward taxable supplies, total ITC claimed, net tax liability, and tax payment. Filed by the 20th of the following month (varies for some states/turnover slabs). GSTR-3B must be reconciled with GSTR-1 (outward supplies) and GSTR-2B (eligible ITC). GST is paid while filing GSTR-3B — no separate payment mechanism.
