GSTR 1 vs GSTR 3B Reconciliation & JSON to Excel is a free, 100% client-side statutory utility by D BIZ CONSULTANCY PVT. LTD. that computes reconcile outward tax liability between GSTR-1 and GSTR-3B to prevent automated DRC-01B notices, and convert portal JSON returns into multi-tab Excel sheets. It operates using the verified formula Variance = (GSTR-1 Tax Liability) - (GSTR-3B Tax Declared & Paid). All calculations and file parsing execute strictly inside your local web browser with zero server uploads or database storage.
Statutory Rule & Legal Thresholds
As of September 30, 2026, automated DRC-01B notices for tax mismatches and DRC-01C notices for ITC mismatches (GSTR-2B vs 3B) are system-generated by GSTN algorithms. Failure to respond within 7 days results in blocking of subsequent GSTR-1 filings under Rule 59(6).
Mathematical Equation & Calculation Logic
Under Rule 88C of the CGST Rules, if outward tax liability reported in GSTR-1 exceeds the liability declared in GSTR-3B by more than a specified percentage (currently 20% or ₹25 Lakhs), the GST portal automatically issues Form DRC-01B requiring payment or explanation within 7 days.
