Round off GST Amount and E Invoice / Way Bill Rejection in Tally prime

Hi Sujit,

This is a common issue many face when using Tally Prime with GST e-invoice and waybill portals due to rounding differences between software and the government portal validation.

Why this happens:

• Tally rounds CGST and SGST separately (e.g., each up to 0.50 paise), but the e-invoice system expects the total GST amount (CGST + SGST) to match exactly with the invoice amount after rounding.

• If Tally rounds CGST and SGST individually, the sum might differ by 1 paise compared to the e-invoice system’s calculation, causing rejection.

How to resolve this:

1. Disable individual round off of CGST & SGST:
   Configure Tally to round off GST as a whole, i.e., round off total tax amount, not individual components.

   • Go to Gateway of Tally > F11: Features > Statutory & Taxation

   • Look for "Allow GST Rounding Off" and "Round Off to nearest" options.

   • Ensure rounding is applied on the total GST amount, not separately on CGST and SGST.

2. Update Tally Prime to Latest Version:
   Ensure you are on the latest Tally Prime release with all GST and e-invoice compliance updates.

3. Use the 'E-Way Bill' & 'E-Invoice' Modules Properly:
   Always generate the invoice through the e-invoice module in Tally itself, which applies correct rounding as per GST rules.

4. Avoid manual adjustments:
   Don’t manually alter GST amounts in the voucher, let Tally handle the calculations automatically.

5. Validate Before Upload:
   Use Tally’s pre-upload validation tool to check the invoice and catch mismatches early.

Summary:

Round off the total GST amount instead of CGST and SGST separately in Tally to avoid mismatch errors with the e-invoice system.
