About the GSTR-1 Checklist

Filing GSTR-1 correctly is crucial to avoid disputes with your B2B customers, as any error or omission will prevent them from claiming their rightful Input Tax Credit (ITC). This checklist maps out the exact steps needed to verify invoice details, state classifications, and document numbers.

📋

B2B Invoice Verification

Ensure client GSTINs are valid, active, and matching business names in your sales books.

📋

B2C Sales Classification

Correctly report state-wise taxable value under B2C Small or Large tables depending on value limits.

📋

Credit & Debit Notes

Verify that all credit notes for sales returns or rate differences match corresponding invoices.

📋

Export & SEZ Supplies

Provide shipping bill numbers and ICEGATE details to claim GST refunds or zero-rated tax benefits.

📋

HSN/SAC Summary Check

Ensure HSN details are entered for all items with correct taxable values and tax rates.

📋

Document Series Check

Enter the starting and ending serial numbers of all invoices, debit notes, and credit notes issued.

📋

Reconciliation with Books

Compare the GSTR-1 portal draft summary directly against your books sales ledger prior to filing.

📋

Amendments & Corrections

Verify that errors from previous returns are corrected under the appropriate amendment tables.
