GST Compliance

GST compliance is integrated into the Finance module

End-to-end GST management — from HSN codes to GSTR filing and e-invoicing.

HSN & SAC Codes

• Manage your HSN (Harmonized System of Nomenclature) code master from GST → HSN Codes.
• Assign HSN codes to products. The code determines the applicable GST rate.
• SAC codes for services work the same way.
• Use the built-in HSN search to find the correct code for your products.

GSTIN Verification

Verify any customer or supplier GSTIN against the GST portal.

• When adding a customer/supplier, enter their GSTIN and click Verify.
• The system fetches their legal name, registration status, state, and business type from the GST portal.
• Invalid or cancelled GSTINs are flagged immediately.

E-Invoice

Generate Government-signed IRN (Invoice Reference Number) + QR codes directly from CoreAxis.

1. Set up GSP credentials in Settings → E-Invoice (Owner/Admin only).
2. Create a B2B sale with a valid customer GSTIN.
3. Click Generate E-Invoice. The system submits the invoice to the NIC (National Informatics Centre) portal.
4. On success, the IRN and signed QR code are embedded in the invoice PDF.
5. Bulk submit: Generate e-invoices for multiple pending invoices at once.
6. Cancel IRN: Cancel an e-invoice within 24 hours (Government limit).

GSTR-1

Generate and export your GSTR-1 return for filing on the GST portal.

1. Go to GST → GSTR-1.
2. Select the period (monthly or quarterly, based on your filing frequency).
3. Click Generate. The system compiles all B2B, B2C, credit notes, debit notes, and export invoices into GSTR-1 tables.
4. Review the report — check for missing GSTINs, HSN codes, or mismatches.
5. Click Export JSON. Upload the JSON file to the GST portal for filing.

GSTR-2A/2B Reconciliation

1. Download your GSTR-2A/2B JSON from the GST portal.
2. Go to GST → GSTR-2 Reconciliation → Import.
3. Upload the JSON file.
4. The system auto-reconciles — matching supplier invoices in the return against your purchase records.
5. Review: Matched, Unmatched (in return but not in your books), Missing (in your books but not in return).

GSTR-3B

Generate your monthly GSTR-3B summary return.

• Go to GST → GSTR-3B and select the period.
• The system calculates output tax, input tax credit, and net tax liability.
• Batch generation is available for processing multiple periods.

GSTR-9 Annual Return

• Generate the annual GST return and the GSTR-9C reconciliation statement.
• The system pulls data from all monthly returns, sales, purchases, and adjustments for the financial year.

E-Way Bills

Generate e-way bills for goods in transit.

1. Go to GST → E-Way Bills → Generate.
2. Enter transport details: vehicle number, transporter, distance, etc.
3. The system generates the e-way bill number.
4. Extend validity if the goods haven't reached the destination within the valid period.

Cess Management

• Configure GST Compensation Cess rates per product (rate-based or ad-valorem).
• Cess is calculated and shown separately on invoices.
• Applicable for products like tobacco, coal, motor vehicles, aerated drinks.

ITC Register (Input Tax Credit)

Track all input tax credit claimed, reversed, and available.

1. Go to GST → ITC Register.
2. The register shows ITC claimed from purchase invoices — broken down by CGST, SGST, IGST, and Cess.
3. View ITC Available vs ITC Utilized vs ITC Reversed.
4. Cross-reference with GSTR-2B to ensure you're only claiming eligible ITC.

GSTR-9C (Reconciliation Statement)

The GSTR-9C is an annual reconciliation statement between your audited financial statements and your GSTR-9.

1. Go to GST → GSTR-9C.
2. The system auto-populates figures from your books and your filed GSTR returns.
3. Review and reconcile any differences between turnover, tax paid, and ITC claimed in books vs returns.
4. Add auditor's recommendations and adjustments.
5. Export the reconciliation statement for your CA/auditor.

Tax Computation

Get a consolidated view of your GST liability computation for any period.

• Output Tax: Total tax collected on sales (CGST + SGST + IGST + Cess).
• Input Tax: Total tax paid on purchases eligible for ITC.
• Net Liability: Output Tax minus Input Tax = amount payable to the government.
• Period Comparison: Compare tax liability across multiple months or quarters side-by-side to spot trends.
