GST Return Filing Tips for July 2026: Avoid Common Errors

July 2026 brings updated GSTR-1 filing requirements and stricter validation on the GST portal. Here are the critical changes and how to avoid rejection.

New Validation Rules

The portal now validates HSN codes at 6 digits for all B2B invoices. Invoice value mismatches between GSTR-1 and GSTR-3B now trigger automatic notices.

Pre-Filing Checklist

Before filing: reconcile GSTR-2B with purchase register, verify all e-invoices are uploaded, check for missing credit notes, and validate POS for interstate B2C supplies.

LekhaFlow's reconciliation module flags mismatches before you file, preventing notices and ensuring 100% compliant returns.
