How to Issue GST-Compliant Invoices as a Freelancer in India

Issuing GST-compliant invoices is legally required for registered businesses and freelancers in India. A valid tax invoice ensures proper documentation for tax filing purposes and allows your corporate clients to claim Input Tax Credit (ITC) on the taxes they pay you.

Frequently Asked Questions

Q: What is the difference between CGST, SGST, and IGST on an invoice?

CGST (Central GST) and SGST (State GST) apply to intra-state supply (when you and client are in the same state) and are split 50/50. IGST (Integrated GST) applies to inter-state supply and is charged as the full tax rate (e.g. 18%).

Q: Do I need to register for GST if I bill clients abroad?

Export of services is treated as zero-rated supply. If your total annual receipts are under ₹20 Lakhs, registration is optional. However, if you are registered, you can file a Letter of Undertaking (LUT) on the GST portal to bill at 0% GST.

Q: What are the mandatory fields required on a GST tax invoice in India?

A compliant GST tax invoice must include: unique sequential invoice number, date of issue, supplier name/address/GSTIN, recipient name/address/GSTIN (for B2B), SAC/HSN code, description of services/goods, taxable value, applicable GST tax rates, and total amount.

Q: What happens if I make a billing error on an issued GST invoice?

If you issue an incorrect invoice that is already uploaded to the GST portal or sent to a client, you cannot delete it. You must issue a Credit Note (to reduce value) or Debit Note (to increase value) referencing the original invoice number.

Q: Can I add multiple line items with different GST rates on Clientora?

Yes. Clientora allows adding unlimited items, assigning specific SAC codes and GST tax rates (0%, 5%, 18%, 40%) per item, and automatically computes the line totals, taxes, and grand total.
