GST Billing Rules & Standards

Important compliance rules for drafting tax invoices and estimates in India.

Tax Invoice vs. Estimate Quote

A formal **Tax Invoice** is a legal document that demands payment and must contain valid GSTIN details of the business. An **Estimate or Quotation** is a pre-bill layout detailing terms, prices, and taxes to client leads before finalizing agreements.

GST Invoicing Limit & PAN rules

For retail commerce in India: • Generating invoices with HSN details is mandatory for B2B sales. • Customers claiming Input Tax Credit (ITC) must supply a valid 15-character GSTIN. • E-Invoicing is mandatory for businesses with turnover exceeding ₹5 crore.

Frequently Asked Questions

What is the difference between CGST, SGST, and IGST?

For sales within the same state (Intra-state), tax splits into CGST (Central GST) and SGST (State GST) equally. For sales across state borders (Inter-state), the full rate accumulates under IGST (Integrated GST).

How does item-wise discount affect the GST calculation?

According to Indian GST rules, GST is calculated on the transaction value *after* subtracting trade discounts. The discount percentage is deducted first, and the tax slab rate is applied to the net taxable value.
