CGST, SGST/UTGST or IGST for Tripura
Compare the supplier's state code with the place of supply. If both are 16, the supply is intra-State and the rate is split as CGST + SGST. If the place of supply is in any other state or UT, the full rate is charged as IGST.

Frequently Asked Questions
Which state has GST state code 16?
16 is the GST state code of Tripura. Every GSTIN registered in Tripura begins with the digits 16.
What is the GST state code of Tripura?
The GST state code of Tripura is 16. It is the first two digits of the 15-character GSTIN.
Does a GSTIN starting with 16 mean the business is in Tripura?
It means the registration belongs to Tripura. A business registers separately in each state it supplies from, so the same company can hold GSTINs with other state codes. The shipping address on an invoice can also differ from the registered state.
Which GST applies on a sale within Tripura?
When the supplier is registered in Tripura and the place of supply is also Tripura, the supply is intra-State, so the rate is split as CGST + SGST. For example, an 18% item is charged as 9% + 9%.
Which GST applies on a sale from Tripura to another state?
Supplies from Tripura (16) to a place of supply in another state or UT are inter-State and carry IGST. For example, a sale to a buyer in Assam (18) is charged IGST at the full rate.
Is Tripura a state or a Union Territory under GST?
For GST, Tripura is classified as: State.
Can one business have more than one GSTIN starting with 16?
Yes. A business can hold several registrations in the same state, for example for separate business verticals. They all start with 16 and share the same PAN in digits 3 to 12, but the 13th character (the entity number) is different.
Is the state code in a GSTIN the same as the place of supply?
No. The state code shows where the supplier or buyer is registered. The place of supply is worked out under the IGST Act rules for goods or services. Comparing the supplier's location with the place of supply decides whether CGST + SGST or IGST applies.
What happens if an invoice uses the wrong tax because of the state code?
If CGST + SGST is charged where IGST was due (or the other way round), the supplier generally has to pay the correct tax and claim a refund of the amount paid under the wrong head. The buyer's input tax credit can also be held up until the invoice is corrected, so check the buyer's GSTIN before invoicing.
Has GST state code 16 ever changed?
No. 16 has been the code for Tripura since GST began in July 2017, and the GST 2.0 rate changes did not affect state codes.
