Why GSTR-2B Auto-Reconciliation is Mandatory in India
The government has eliminated provisional credit. Here is what every business owner and CA must know.
1. Section 16(2)(aa) Rule
You can only claim Input Tax Credit if the supplier has actually uploaded the invoice details in their GSTR-1 and it is reflected in your GSTR-2B. Claiming unreflected credit leads to automated scrutiny notices and 18% annual interest penalties.
2. Automated Vendor Follow-Ups
Instead of arguing with suppliers over missing invoices at year-end, Katixo sends instant WhatsApp reminders with exact invoice numbers before the 11th of each month, holding payments automatically if GSTR-1 is not filed.
3. Post-GST-2.0 Rate Discrepancies
With Notification 9/2025-CT(Rate) dropping medical devices and generic pharma to 5% while leaving nutraceuticals at 18%, suppliers frequently bill with outdated tax codes. Katixo flags line-by-line rate conflicts before you file GSTR-3B.
4. Zero Double Data Entry
When using Katixo AI ERP, your purchase register reconciles continuously with the GST portal in real-time. No manual Excel exports, no VLOOKUP headaches, and no midnight filing rushes.
