What Must a GST Invoice Include? (Legal Requirements)
Understanding CGST, SGST, and IGST
Example: Invoice value ₹10,000 at 18% GST (intra-state) = CGST 9% (₹900) + SGST 9% (₹900) = Total GST ₹1,800. Grand Total: ₹11,800.
Frequently Asked Questions
What is GSTIN and where do I find it?▼
GSTIN is your 15-digit GST Identification Number issued on GST registration. Find it on your GST registration certificate or the GST portal at gst.gov.in.
Do I need to include HSN codes on every GST invoice?▼
Mandatory for businesses with turnover above Rs.5 crore (6-digit HSN). For turnover between Rs.1.5–5 crore, 4-digit HSN is sufficient. Below Rs.1.5 crore, HSN is optional.
What if my client is not GST registered?▼
For unregistered buyers (B2C transactions), the GSTIN field is optional. Include the buyer's name and address. No reverse charge applies for most B2C transactions.
Can I generate a GST invoice for services?▼
Yes. Use SAC (Services Accounting Code) instead of HSN code for service invoices. SAC codes are available on the GST portal.
What is the difference between CGST, SGST, and IGST?▼
CGST (Central GST) + SGST (State GST) apply to intra-state transactions — both at half the total rate. IGST (Integrated GST) applies to inter-state transactions at the full rate.
