# GST in Validure ERP: frequently asked questions > How Validure ERP handles GST: CGST, SGST and IGST by Place of Supply, Input Tax Credit, Section 49 set-off, GSTR-1 and GSTR-3B, and what it does not do. Validure ERP works out CGST and SGST or IGST on every invoice line from the branch's state and the Place of Supply, tracks Input Tax Credit on purchases, and prepares GSTR-1 and GSTR-3B figures with the Section 49 set-off. It does not file returns on the GST portal: you file there and record the ARN in Validure ERP. This FAQ explains how Validure ERP works. It is not tax advice; check your own position with your tax adviser. ## Tax on invoices ### How does Validure ERP decide between CGST plus SGST and IGST? Validure ERP compares the state code of the branch issuing the invoice with the state code of the Place of Supply. If they are the same, the supply is intra-state and each line carries CGST and SGST at half the GST rate each; if they differ, it is inter-state and each line carries IGST at the full rate. For example, 5% GST on an intra-state line is 2.5% CGST plus 2.5% SGST. ### Where does the Place of Supply on a Validure ERP invoice come from? Validure ERP fills the Place of Supply from the customer's state when you choose the customer, and shows the resulting tax mode beside it, such as Inter-state · IGST. You can change the Place of Supply before you save, and the tax split follows the new state.

Validure ERP rounds each line's tax to the paisa and rounds the invoice grand total to the nearest rupee, showing the difference as a separate Round off line. The round off always stays between −₹0.50 and +₹0.49, so taxable value plus taxes plus round off equals the grand total exactly. ### Are Validure ERP invoices laid out for Rule 46? Yes, Validure ERP prints Tax Invoices laid out for Rule 46 of the CGST Rules: your GSTIN and state, the customer's details and GSTIN, the invoice number and date, the Place of Supply, Reverse Charge, the HSN or SAC code on each line, taxable value, tax rate and amount, an HSN summary and a signatory block. Composition or exempt supplies print as BILL OF SUPPLY instead of TAX INVOICE. ## Input Tax Credit and set-off ### How does Validure ERP track Input Tax Credit? Validure ERP lets you tag the GST on each purchase bill as Eligible ITC, Ineligible / Blocked ITC under Section 17(5), or Capital Goods ITC, and counts eligible credit from purchase bills and expenses in the GST summary. It does not import GSTR-2B, so check your credit against GSTR-2B on the GST portal before you claim it. ### In what order does Validure ERP apply the Section 49 set-off? Validure ERP uses IGST credit first, against IGST, then CGST, then SGST. CGST credit then pays CGST and then IGST, and never SGST; SGST credit pays SGST and then IGST, and never CGST. Whatever is still payable is paid in cash from the Electronic Cash Ledger.

No, Validure ERP computes the set-off in the fixed order above, and you do not type or rearrange the amounts. Rule 88A allows IGST credit left after paying IGST to be used against CGST and SGST in any order, which can lower the cash payable in some months; Validure ERP does not offer that choice. ### Can I record GST paid by challan in Validure ERP? Yes, Validure ERP records each challan deposit into the Electronic Cash Ledger with its challan CIN, payment date, bank account and the amount split across IGST, CGST, SGST, interest and penalty. The set-off then uses that cash balance for whatever credit does not cover. ## Returns and filing ### Does Validure ERP file GST returns on the GST portal? No, Validure ERP does not file returns on the GST portal. It prepares GSTR-1 and GSTR-3B figures in the portal's table layout for you to download and file yourself, and after filing you record the ARN and filing date in Validure ERP.

Validure ERP prepares GSTR-1 in a ready format with B2B invoices (Table 4A), B2C large inter-state invoices (Table 5A), export invoices (Table 6A), B2C small (Table 7), credit and debit notes (Table 9B) and the HSN summary (Table 12). You can download the figures as an Excel file. ### Does Validure ERP remind me about GST due dates? Yes, the Validure ERP dashboard warns you as the monthly due dates approach: the 11th for GSTR-1 and the 20th for GSTR-3B. The alerts follow these monthly dates, so check the GST portal for quarterly (QRMP) due dates. ### Does Validure ERP generate e-invoices or e-way bills? No, generating e-invoice IRNs and e-way bills is not part of Validure ERP's specification. If your business must issue e-invoices or e-way bills, you need a separate tool for that. ## GSTINs and branches ### Can one Validure ERP company have more than one GSTIN? Yes, each branch in Validure ERP can carry its own GSTIN and state, and every invoice and stock movement belongs to a branch. The GST dashboard and returns are prepared per GSTIN, each branch can have its own invoice number series, and multi-branch is included in the Gold and Platinum plans. ### Does Validure ERP check GSTINs? Yes, Validure ERP checks that a GSTIN has the right 15-character format and that its first 2 digits match the party's state code, and imports also check GSTIN checksums. A mismatch is shown next to the field, for example: GSTIN state code 27 doesn't match West Bengal (19). ## A set-off worked through (demo data) August 2026 GSTR-3B settlement for GSTIN 19ZLMFM5780A1ZS of the fictional demo company Meghmala Fresh, recorded as set-0006. | Set-off step | Amount | |---|---:| | IGST credit used against IGST | ₹17,984.34 | | CGST credit used against CGST | ₹12,593.77 | | SGST credit used against SGST | ₹12,839.77 | | SGST credit used against IGST | ₹975.81 | | Paid in cash from the Electronic Cash Ledger (IGST ₹419.06, CGST ₹246.00) | ₹665.06 | | Total liability for the month | ₹45,058.75 | The return was filed on 19 Sep 2026, before the 20 Sep 2026 due date, and the ARN AA1909269158794 was recorded in Validure ERP. --- Canonical page: https://erp.validuresolutions.com/product/gst-faq.html Validure ERP is a product of Validure Solutions Pvt.
