GST invoice format for Telangana (state code 36)
Hyderabad's HITEC City and Gachibowli generate an enormous amount of small-business software, design and consulting work. Telangana's own history leaves a trap for invoices, though: the state was split from Andhra Pradesh in 2014, and the two now have different GST codes, 36 for Telangana and 37 for Andhra Pradesh.
A Hyderabad freelancer billing a Vijayawada client is making an inter-state supply and must charge IGST. A Hyderabad freelancer billing a Warangal client charges CGST and SGST. This page shows the Telangana to Andhra Pradesh case with IGST so the difference is visible, and lists what to check on your client's GSTIN before sending it.

Points that matter when invoicing from Telangana
- 36 is Telangana, 37 is Andhra. Check the first two digits of the client's GSTIN. A company with a Hyderabad address but a GSTIN starting 37 is registered in Andhra Pradesh, and the supply would be inter-state.
- Older GST documents. Some old documents and templates show Andhra Pradesh's pre-split code, 28. Active GSTINs in Andhra Pradesh now start with 37, so avoid copying code 28 from a legacy invoice.
- Start-up client invoices. Funded start-ups in Hyderabad often ask for payment against a monthly purchase order. Put the PO number and the billing period on the invoice to avoid a hold in their accounts payable cycle.
- SEZ and IT park clients. If your client is a unit in an SEZ, supply is inter-state for GST purposes and IGST or zero-rating under LUT applies, even when the park is minutes from your home.
Fields every Telangana GST invoice needs
Every tax invoice from a Telangana seller must carry your name, address and GSTIN (starting 36), a unique invoice number and date, the client's name and address, the place of supply, HSN or SAC code, taxable value, tax rate and amount, and the total. The full list is in our guide to mandatory GST invoice fields.
