What Makes a Valid GST Invoice?

Under Rule 46 of the CGST Rules, a tax invoice must contain:

• Supplier's name, GSTIN, and address
• Invoice number (unique within a financial year)
• Date of issue
• Recipient's name, GSTIN (if registered), and address
• Place of supply (with state name and code)
• Description of goods or services, HSN code (for goods), SAC code (for services)
• Quantity and unit
• Total value before tax
• Taxable value after discounts
• Rate of tax (CGST, SGST, IGST separately)
• Amount of tax charged
• Total amount after tax
• Whether tax is payable on reverse charge basis

This tool validates a subset of these requirements — specifically the GSTIN format, tax breakdown consistency, and basic invoice completeness. A full compliance check requires additional information.
