What documents are needed to file GSTR-3B?

The month's GSTR-2B statement, an outward supplies summary that matches GSTR-1, the purchase register with ITC workings, and the electronic cash and credit ledger balances.

What should I check before filing GSTR-3B?

That the declared liability agrees with GSTR-1 (a gap invites a DRC-01B notice), ITC claimed is within GSTR-2B (excess invites DRC-01C), reverse charge is added, and interest is computed for late payment.

Is my checklist progress saved?

What is the HSN requirement in GSTR-1?

Taxpayers with turnover up to ₹5 crore report 4-digit HSN codes; above ₹5 crore, 6-digit codes are mandatory in Table 12.

Why a Checklist Beats Memory

Most GST notices are not about fraud — they are about mismatches. A GSTR-3B that disagrees with GSTR-1 invites a DRC-01B intimation; ITC claimed beyond GSTR-2B invites DRC-01C. Both checks take two minutes before filing and weeks of correspondence after. The pre-filing sections above exist because of exactly those two notices.

Your ticks are stored only in this browser — nothing is uploaded. Use the GSTR-3B reconciliation helper for the liability and ITC checks, the due-dates calendar for the deadline, and the late-fee calculator if one slipped.
