GST Calculation Automation

GST Calculation Automation is a tax workflow solution that automates multi-rate GST computation, validates HSN/SAC classifications, matches supplier invoices against government GSTR-2B portal data, checks Input Tax Credit (ITC) eligibility, and prepares error-free return-ready filings.

The system automatically inspects supplier GSTIN, recipient GSTIN, and the legal Place of Supply (POS). It dynamically applies Intra-State (CGST + SGST/UTGST) or Inter-State (IGST) tax rules, eliminating costly tax jurisdiction misclassification errors.

Yes. The system validates 4, 6, or 8-digit HSN and SAC codes against statutory CBIC GST rate master databases, instantly catching incorrect tax percentage applications (e.g., applying 12% instead of 18%) prior to invoice generation or accounting entry.

The system ingests the official monthly GSTR-2B JSON/Excel downloads from the GST Portal and automatically compares invoice numbers, supplier GSTINs, invoice dates, taxable values, and tax amounts against your internal purchase register using fuzzy matching rules.

The reconciliation engine groups discrepancies into clear categories: Matched, Value Mismatch, Missing in GSTR-2B, Missing in Books, and Ineligible ITC (e.g., blocked credits under Section 17(5)). This allows finance teams to claim only 100% eligible ITC.

Yes. The engine processes complex invoices with multiple line items carrying different tax slabs (0%, 5%, 12%, 18%, 28%) as well as compensation cess, accurately computing item-wise and invoice-level totals.

Yes. The solution connects seamlessly via direct database connectors, APIs, or automated Excel/CSV bridges with SAP ECC, SAP S/4HANA, Tally Prime, Oracle ERP, Microsoft Dynamics, and custom accounting packages.

By identifying supplier non-compliance, invoice number typos, and ITC mismatches weeks before the GSTR-3B filing deadline, the system enables finance teams to resolve discrepancies proactively and avoid statutory interest penalties.

The system generates one-click monthly reconciliation dashboards, vendor-wise discrepancy statements ready to be emailed to defaulting suppliers, and statutory summary sheets matching GSTR-1, GSTR-3B, and GSTR-2B formats.

Depending on invoice volumes and ERP complexity, standard implementations are completed within 5 to 10 working days, providing immediate clarity on input tax credit reconciliation for the upcoming tax cycle.

The system can mark it as an ITC mismatch or missing supplier upload. The accounts team can then follow up with the supplier before claiming or finalizing the credit.

The difference can be flagged with the exact mismatch, such as taxable value, GST rate, invoice number, or tax amount. Users can review the invoice and take corrective action.

Yes. Such invoices can be shown as unrecorded or unmatched supplier invoices so the team can verify whether the purchase was missed, wrongly recorded, or does not belong to the business.

Yes. The dashboard can show output tax, eligible ITC, ineligible ITC, reversals, adjustments, and estimated net GST liability based on the available records and configured rules.

Yes. The system can check GSTIN format, state code consistency, duplicate registrations, and master-data mapping. Additional validation may depend on available government or third-party integrations.

Yes. It can organize sales, purchase, tax, HSN, and ITC data into return-ready summaries and reports. Final filing should still follow the organization’s approval and compliance process.

Yes. A monthly compliance dashboard can show preparation status, pending validations, ITC review, unresolved exceptions, and records requiring correction before return filing.

Yes. Each exception can include a specific reason, such as invalid GSTIN, incorrect tax rate, HSN mismatch, duplicate invoice, missing invoice number, incorrect tax split, or ITC mismatch.

Yes. The audit trail can record the previous value, updated value, user name, date, time, approval status, and reason for the change.

It reduces repetitive calculations, minimizes tax errors, improves ITC reconciliation, speeds up monthly compliance work, highlights exceptions early, and provides audit-ready reports. This helps the finance team save time and reduce compliance risks.
