<h1>Auto-Population in GSTR-3B from GSTR-1 & GSTR-2B Enabled for Monthly Filers; Verify & Edit Before Submission.</h1> Auto-population of details in Form GSTR-3B from Form GSTR-1 and GSTR-2B has been enabled for taxpayers filing monthly from November 2020. The system computes liabilities based on outward supplies in Form GSTR-1 and Input Tax Credit from Form GSTR-2B. These values are available in PDF format on the GSTR-3B dashboard. Taxpayers must verify and can edit these values. Alerts are issued for significant variances. If GSTR-1 or GSTR-2B is not filed, values are marked as 'Not filed' or 'Not generated.' Pre-saved values in GSTR-3B remain unchanged, and certain tables are not auto-populated.
