Frequently Asked Questions

What is a GST invoice?

A GST invoice is a tax document issued by a registered GST taxpayer when supplying goods or services. It must include GSTIN, HSN/SAC codes, taxable value, GST rates, and total amount. InvoiceAI auto-fills all fields correctly.

Who needs to issue GST invoices in India?

Any business or freelancer registered under GST whose annual turnover exceeds ₹20 lakhs (₹10 lakhs for special category states) must issue GST invoices. InvoiceAI supports both regular and composition taxpayers.

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

CGST (Central GST) and SGST (State GST) apply to intra-state transactions — each is usually half of the total GST rate. IGST (Integrated GST) applies to inter-state transactions and equals the full GST rate. InvoiceAI detects supplier and buyer state and applies the correct tax automatically.
