GST state code 16: Tripura
Tripura's GST state code is 16. Natural rubber sheets, Queen pineapples and bamboo furniture are billed from GSTINs that start with 16.
In short
Tripura has GST state code 16, so every GSTIN registered there begins with 16. A local sale carries CGST and SGST; a sale to Assam carries IGST. SimpleERP reads 16 from the buyer's GSTIN and picks the tax.

What the code 16 means on a GSTIN
A GSTIN has 15 characters. Take the sample 16AAACL1234A1ZC, a made-up number with a valid check character. 16 is the state code for Tripura. AAACL1234A is the PAN of the business, and 1 says this is the first registration under that PAN in Tripura. Z is the same on almost every GSTIN, while C is a check character worked out from the first 14, so a single wrong digit in 16AAACL1234A1ZC fails the check.
Tripura is one of India's larger natural rubber producers, and much of its rubber goes to factories in other states. A rubber dealer in Agartala selling sheets to a buyer in Guwahati charges IGST because the buyer's GSTIN starts with 18. Sales to buyers in Dharmanagar or Belonia, inside Tripura, carry CGST and SGST.
Intra-state or inter-state: which tax applies when the supplier is in Tripura?
When an Agartala rubber dealer sells sheets to a footwear unit in Dharmanagar, supplier and place of supply are both in Tripura, so the invoice carries CGST and SGST. When the dealer ships to a factory in Guwahati, the place of supply moves to Assam and the whole tax becomes IGST; the same holds when the dealer supplies a workshop in Port Blair, because Andaman and Nicobar Islands has its own code, 35.
| Sale | Place of supply | Tax at 18% | Tax on ₹3,00,000 |
|---|---|---|---|
| An Agartala rubber dealer sells sheets to a footwear unit in Dharmanagar | Tripura (16) | CGST 9% + SGST 9% | ₹27,000 + ₹27,000 |
| The dealer ships to a factory in Guwahati | Assam (18) | IGST 18% | ₹54,000 |
| The dealer supplies a workshop in Port Blair | Andaman and Nicobar Islands (35) | IGST 18% | ₹54,000 |
Does professional tax apply in Tripura?
Yes. Tripura levies professional tax on salaries, as notified; check the current slabs with the Tripura tax department before you deduct it, since this page lists no Tripura slab amounts. In SimpleERP payroll, Professional Tax is a fixed deduction on the payslip that starts at zero, so you enter the Tripura amount once.
How SimpleERP reads the state from a GSTIN
You never type 16 or Tripura on an invoice: SimpleERP takes both from the customer's GSTIN and works out the rest.
- The state fills from the first two characters of the GSTIN: type 16AAACL1234A1ZC and SimpleERP shows Tripura (16) under the field, after checking the last character.
- The place of supply comes from the buyer's GSTIN, so a Assam buyer fills Assam (18); a buyer without a GSTIN gets the state picked once on the customer record.
- Each invoice line compares the place of supply with your Tripura branch and carries CGST and SGST, or IGST.

FAQ
Questions, answered
What is the GST state code for Tripura?
Tripura uses GST state code 16. Every GSTIN registered in Tripura, from Agartala to Dharmanagar, starts with 16. Assam, its main trade link, is 18, and Mizoram is 15, so the first two digits show at once whether a buyer is local.
Is code 16 used for SGST or UTGST?
SGST. Tripura is a state, so a sale within Tripura carries CGST and SGST at half the rate each. UTGST is charged only in union territories without their own legislature. The buyer pays the same total either way.
Which code do I use for a customer in Tripura?
The buyer's GSTIN code: 16 for a buyer registered in Tripura. A factory in Guwahati has 18, so a sale to it is inter-state and carries IGST. For an unregistered buyer, use the state where the rubber or goods are delivered.
Does SimpleERP need me to pick Tripura by hand?
No. SimpleERP fills the state from the customer's GSTIN, so an Assam buyer shows as Assam (18) the moment you type the number. Each line on the invoice then carries IGST, or CGST and SGST for a buyer in Tripura.
