GST for businesses in Chennai
- State / UT
- Tamil Nadu
- GST state code
- 33 (first two digits of a Tamil Nadu GSTIN)
A sale from Chennai to a customer within Tamil Nadu is an intra-state supply, so you charge CGST + SGST. Selling to a customer in another state is an inter-state supply, so you charge IGST. The total tax is the same — only the split differs. ईnvocify applies the right split automatically from the place of supply. Learn how the GST split works.
The same invoice, billed two ways from Chennai
Take a ₹50,000 invoice at an 18% GST rate. The rate is an example — yours depends on what you sell — but the split works the same way at any rate.

You collect ₹9,000 either way. What changes is which government receives it and which boxes it lands in on your GSTR-1 — which is why getting the place of supply wrong is a filing problem rather than a pricing one. Businesses in Chennai commonly bill into Andhra Pradesh, Karnataka and Kerala, so both cases come up in the same week. Verify any rule against the official GST portal.
What businesses in Chennai are usually invoicing for
Chennai is known for automotive and components, engineering and IT services.
Chennai's automotive supply chain bills in repeating monthly cycles against standing purchase orders, frequently with the same line items every single month. Recurring invoices and consistent HSN codes do more work here than anything about how the invoice looks.

GST invoicing in Chennai: FAQ
I bill the same automotive client identical line items every month. Can that be automated?
Yes — that is exactly what recurring invoices are for. The value is not saving typing; it is that the HSN codes, tax rates and line descriptions stay identical month to month, which is what keeps your GSTR-1 consistent and your client's ITC clean.
Does a purchase-order number belong on a GST invoice?
GST does not require it, but most Chennai manufacturing buyers will not process an invoice without it, because their own three-way match depends on it. Treat it as a commercial requirement rather than a tax one.
Do I charge CGST + SGST or IGST for a sale within Chennai?
For a sale where both you and your customer are in Tamil Nadu (an intra-state supply), you charge CGST + SGST. When you supply to a customer in another state, you charge IGST instead. The total GST rate is the same either way — only the split changes. ईnvocify applies the correct split automatically based on the place of supply.
What is the GST state code for Tamil Nadu?
The GST state code for Tamil Nadu is 33 — it's the first two digits of every GSTIN registered in the state. ईnvocify reads the state code from your and your customer's GSTIN to decide the correct tax treatment.
Can I generate e-invoices (IRN) and e-way bills in Chennai?
Yes. E-invoicing (IRN) and e-way bills run through central government systems and apply the same way across India. ईnvocify generates both in-app when they apply to your supply.
Is there a free trial for businesses in Chennai?
Yes. ईnvocify offers a 7-day free trial with no credit card required, so any business in Chennai can try GST invoicing, reminders, and reports before paying.
