GST Invoice Format for Freelancers: The Ultimate Guide

As a freelancer registered under GST, issuing a proper tax invoice is mandatory. A compliant invoice not only ensures you follow the law but also projects professionalism to your clients.

Mandatory Fields in a GST Invoice

According to GST rules, your invoice must contain the following details:

1. Invoice Number & Date: A unique consecutive serial number.
2. Your Details: Name, Address, and GSTIN.
3. Client Details: Name, Address, and GSTIN (if registered).
4. Place of Supply: Crucial for determining IGST vs CGST/SGST.
5. SAC Code: Service Accounting Code (e.g., 9983 for IT services).
6. Description of Services: Clear description of work done.
7. Taxable Value: The amount before tax.
8. Tax Rate & Amount: Breakdown of CGST, SGST, or IGST.
9. Total Value: Final amount payable.
10. Signature: Digital or physical signature.

Digital Signatures

You don't strictly need a Class 3 Digital Signature Certificate (DSC) for invoices sent via email. A scanned image of your physical signature or a digital sign-off is generally accepted for freelance work, though using a secure digital signature is better for authenticity.
