GST Tax Invoice (India)

A GST Tax Invoice must contain specific mandatory particulars prescribed under Section 31 of the CGST Act 2017 and Rule 46 of the CGST Rules 2017. Failure to include any mandatory particulars renders the invoice non-compliant, which can result in the recipient being unable to claim input tax credit on that invoice under Section 16 of the CGST Act 2017. The mandatory particulars are: (1) Name, address, and GSTIN of the supplier; (2) Consecutive serial number (not exceeding 16 characters, using alphabets, numerals, or special characters including hyphen, dash, and slash); (3) Date of issue of the invoice; (4) Name, address, and GSTIN of the recipient (for B2B supplies); (5) For unregistered recipients (B2C) where the supply value exceeds Rs 50,000 — name, address, and state of the recipient; (6) HSN Code for goods (4-digit for turnover between Rs 5 and Rs 50 crore; 6-digit for turnover above Rs 50 crore) or SAC code for services; (7) Description of goods or services; (8) Quantity of goods (unit and quantity); (9) Total value of supply of goods or services; (10) Taxable value of supply after deducting any discount; (11) Rate of tax (CGST, SGST, IGST, cess); (12) Amount of tax charged in respect of taxable goods or services; (13) Place of supply along with name of state for inter-state supply; (14) Address of delivery if different from address of recipient; (15) Whether tax is payable on reverse charge basis; and (16) Signature or digital signature of the supplier or their authorised representative.

E-invoicing (Electronic Invoicing) under GST is a system introduced by the GSTN (GST Network) under Notification No. 61/2020-Central Tax and subsequent notifications, whereby B2B invoices (and certain other specified documents) issued by notified registered persons must be reported to the Invoice Registration Portal (IRP) in real-time, and the IRP authenticates and returns the invoice with a unique Invoice Reference Number (IRN) and a QR code. The QR code contains the invoice summary and the digital signature of the IRP, making the invoice tamper-proof and verifiable. E-invoicing was introduced in phases based on aggregate annual turnover thresholds: from 1 October 2020 for taxpayers with turnover above Rs 500 crore; from 1 January 2021 for turnover above Rs 100 crore; from 1 April 2021 for turnover above Rs 50 crore; from 1 April 2022 for turnover above Rs 20 crore; from 1 October 2022 for turnover above Rs 10 crore; and from 1 August 2023 for turnover above Rs 5 crore. The e-invoicing mandate applies to B2B supplies, supplies to SEZ units, and exports. It does not apply to B2C supplies, banking and financial institutions, NBFCs, goods transport agencies, passenger transport services, and certain other notified persons. Under the e-invoicing system, the supplier generates the invoice in their accounting or ERP system, uploads it to the IRP via API, receives the IRN and QR code, and then shares the authenticated invoice (with IRN and QR) with the buyer. Without the IRN, the invoice is not valid for ITC purposes.

Issuing a non-compliant GST Tax Invoice in India has serious legal and commercial consequences under the CGST Act 2017. For the supplier, the consequences include: under Section 122 of the CGST Act 2017, issuing an invoice without compliance with the provisions of the Act or Rules attracts a penalty of Rs 10,000 or 100% of the tax due on such transaction, whichever is higher. Specifically, Section 122(1)(i) penalises failure to issue invoice or bill of supply as required; Section 122(1)(viii) penalises issuing incorrect invoices. Under Section 132, if the value of supply on the invoice is deliberately suppressed to evade tax exceeding Rs 5 crore, the offence is cognisable and non-bailable, attracting imprisonment up to 5 years with fine. For the recipient, the consequences are equally serious: a non-compliant invoice does not qualify as a valid tax invoice for the purpose of claiming input tax credit under Section 16(2)(a), which requires the recipient to possess a valid tax invoice. Additionally, a GST invoice that lacks the supplier GSTIN, is not authenticated via IRP (where e-invoicing is mandatory), or lacks the mandatory particulars under Rule 46, will not appear in the recipient GSTR-2B auto-populated ITC register, making ITC unavailable. The GSTN system automatically blocks ITC on invoices that are not reported in GSTR-1 by the supplier. Businesses therefore have strong commercial incentives to ensure their invoices are fully compliant to protect their own ITC claims and those of their customers.

A GST Tax Invoice (India) does not legally require a lawyer in India, and individuals and businesses may draft and execute the document independently. The Central Goods and Services Tax Act, 2017 does not mandate legal representation for the creation or signing of this type of document. However, seeking independent legal advice from a qualified India lawyer is recommended for transactions involving substantial financial value, complex regulatory requirements, or cross-border elements where multiple legal jurisdictions may apply. A lawyer can verify that the document complies with all applicable statutory requirements, identify potential risks specific to the transaction, and confirm that the terms adequately protect the interests of all parties involved. The Supreme Court of India has jurisdiction over disputes arising from this type of document, and Registrar of Companies (ROC) may impose additional compliance obligations depending on the nature of the underlying transaction. Professional legal review is particularly advisable where the document will be submitted to government agencies or used as evidence in legal proceedings.
