Frequently Asked Questions
Complete Guide to GST Invoicing in India
What is a GST Invoice?
Under the Goods and Services Tax (GST) regime in India, an invoice or a bill is a crucial document that proves a transaction involving the supply of goods or services. A valid GST tax invoice is legally required to claim the Input Tax Credit (ITC) by the buyer. It ensures transparency and compliance with government tax regulations.
Mandatory Fields on a Tax Invoice
According to CBIC guidelines, a valid tax invoice must contain the following details:
- Invoice number and date of issue.
- Customer name, billing address, and shipping address.
- GSTIN of both the supplier and the recipient (if registered).
- HSN Code (Harmonized System of Nomenclature) or SAC (Services Accounting Code).
- Detailed description of goods/services, quantity, and value.
- The correct tax rate (CGST, SGST, or IGST) and tax amount.
- Signature of the supplier or their authorized representative.
B2B vs B2C Invoices: What's the Difference?
In a B2B (Business to Business) transaction, both the supplier and the buyer are GST-registered. The buyer's GSTIN must be on the invoice so they can claim ITC. In a B2C (Business to Consumer) transaction, the buyer is an unregistered entity or end-consumer. B2C invoices do not require the buyer's GSTIN, and the tax paid cannot be claimed as an input credit by the buyer. Zyncro's free invoice maker supports both formats seamlessly.
