GST Registration in Telangana

Telangana sits at the centre of India's IT services, generic pharma, GCC and fintech map. Hyderabad alone hosts captive units of half the Fortune 500, Genome Valley runs the largest cluster of pharma SEZs in the country, and HITEC City keeps adding floor plates faster than tenants can sign leases. Every one of those businesses needs a GST registration that is set up correctly on day one.

Getting the GSTIN is the easy part. Picking the right jurisdiction, configuring SEZ or export treatment, lining up LUT, and surviving biometric verification without restarting the file — that is where most applications stumble. This page walks you through what your Telangana GST registration should actually look like for FY 2026-27, and how to avoid the small mistakes that quietly delay refunds for months.

At a Glance

• Who needs it: Any business in Telangana with turnover over ₹20 lakh (services) or ₹40 lakh (goods), plus all exporters, e-commerce sellers, inter-State suppliers, SEZ units and casual taxable persons regardless of turnover.
• Governing law: CGST Act 2017, SGST Act 2017 (Telangana), IGST Act 2017, and CGST Rules 2017 — read together with Rule 8 (biometric authentication) and Rule 9 (registration grant).
• Jurisdiction: Hyderabad CGST Commissionerate or Telangana State Tax circle, decided by turnover band and PIN code under the Centre-State allocation.
• Turnaround: 7-15 working days for a clean file. Aadhaar-OTP cases clear faster; biometric-flagged cases take 10-15 days.
• Key application form: REG-01 on the GSTN portal with Part A (basic) and Part B (detailed) sections.
• Validity: Permanent until surrendered, cancelled by department, or moved on PAN restructuring.
• Sector hotspots: Genome Valley, Maheshwaram and Fab City SEZs; HITEC City and Gachibowli for IT and GCCs; Banjara Hills and Jubilee Hills for fintech and consulting.

What's New for FY 2026-27

A handful of GSTN and Telangana-specific changes shape how your registration and first year of compliance will run.

• Invoice Management System (IMS) is live: Buyers now accept, reject or keep pending each invoice flowing into their GSTR-2B. Your registration must be configured so vendor invoicing flows match IMS workflow from the first month.
• E-invoicing at ₹5 crore: Any registered person crossing ₹5 crore aggregate turnover in any prior year must issue e-invoices through an IRP. Most Telangana IT, GCC and pharma units are squarely inside this net — flag it at registration.
• Biometric Aadhaar authentication: Rule 8 is now applied across Telangana through GST Suvidha Kendras. Higher-risk applicants are routed to in-person verification at the chosen GSK; lower-risk applicants finish on Aadhaar OTP.
• GSTR-1A correction window: You can now amend outward supplies in the same tax period before filing GSTR-3B. This matters for export-heavy Hyderabad firms running monthly close cycles.
• Form GSTR-9 annual return: Due 31 December following the financial year; aligned with reconciled books, AIS, and TDS / TCS credit captured through the year.
• TS-iPASS and Telangana startup policy: State industrial approvals are now better synced with GSTN data; aligning your registered address and principal place of business with TS-iPASS records avoids field-officer queries.

Who Actually Needs a Telangana GSTIN

Threshold-only thinking misses half the businesses that must register. Use this as a cleaner checklist.

• IT and SaaS exporters: Even if all clients are abroad and revenue is in USD, you are an exporter of services and must register before raising the first invoice.
• Hyderabad-based GCCs and captives: Foreign-parent captives providing back-office, R&D or engineering services to the parent are distinct persons under Schedule I and must register.
• Pharma manufacturers and CDMOs: Genome Valley, Fab City and Pashamylaram units crossing ₹40 lakh goods turnover need GST; SEZ units register and flag SEZ status separately.
• E-commerce sellers and aggregators: Anyone selling through Amazon, Flipkart, Meesho or own D2C platforms must register regardless of turnover, under Section 24.
• Inter-State suppliers: Selling outside Telangana even once forces registration; the ₹20 / ₹40 lakh threshold does not apply.
• Casual taxable persons: Exhibition stalls at HICC, pop-up retail at Inorbit, or short-term project supplies require a casual GSTIN with advance tax deposit.
• Reverse-charge recipients: Importers of services, recipients of GTA services, and units paying directors' fees — registration is mandatory even if outward turnover is nil.

How It Actually Works

The registration moves through six clean stages. Most delays come from skipping the briefing at Stage 1.

Step 1: Eligibility and sector brief

We start with a short call to map your turnover trajectory, business model, export markets and SEZ exposure. An IT services firm exporting to the US is structured differently from a CDMO supplying domestic pharma majors, and a Genome Valley SEZ unit is structured differently again.

We confirm whether you need Hyderabad CGST or Telangana State jurisdiction, whether you will operate under LUT or pay IGST and claim refund, and whether ISD or cross-charge will be needed across branches.

Step 2: Document pack and DSC

We collect PAN, Aadhaar, photographs, address proof, bank documents, MOA and AOA, and the board resolution authorising the signatory. A Class-3 DSC is issued in the authorised signatory's name — Aadhaar-OTP-only registration is possible but the DSC saves you trouble in every later filing.

Address proof is the single most-rejected item. Lease, landlord NOC, latest electricity bill and property tax receipt all need to match exactly with the address you key into REG-01.

Step 3: REG-01 filing

Part A is filed with PAN, mobile and email — an OTP-verified TRN is generated. Part B is completed within 15 days with full business details, place-of-business specifics, HSN / SAC, and bank details.

ARN is generated on submission. From this point the GSTN risk engine decides whether you will be cleared on Aadhaar OTP or routed to biometric verification.

Step 4: Biometric verification, where triggered

If flagged, the system issues a slot at a Telangana GST Suvidha Kendra. The authorised signatory carries originals of PAN, Aadhaar and the registration documents to the GSK on the appointed date.

Fingerprints and a photograph are captured, documents are verified physically, and a Verification Report is uploaded by the officer. Missing the slot delays the file by another 7-10 days.

Step 5: GSTIN allotment

Once verification clears, GSTIN is allotted under Rule 9. The registration certificate (REG-06) can be downloaded from the portal and must be displayed at every place of business.

If the proper officer raises a query through REG-03, a response is filed in REG-04 within 7 working days. Ignoring the query is the fastest way to get the application rejected.

Step 6: Post-registration configuration

We file the LUT (RFD-11) for the financial year if you are an exporter, register on the IRP for e-invoicing if you cross ₹5 crore, set up the return calendar for GSTR-1, GSTR-3B and IFF, and link e-way bill credentials.

For multi-branch businesses we configure ISD registration for common ITC and the cross-charge invoicing format between branches.

A Real Example: Hyderabad GCC with US Parent

Picture a Gachibowli engineering captive providing R&D services to its US parent. Headcount of 120, expected annual billing of ₹38 crore.

• Set-up: Private limited company, 100% subsidiary of US parent. Registered office at HITEC City; one delivery centre at Raidurg.
• GST analysis: Services to foreign parent qualify as export of services under Section 2(6) IGST Act, provided invoicing in USD and FIRC realisation are intact. Distinct-person test under Schedule I applies.
• Path chosen: LUT route — no IGST charged on exports; ITC on rent, software subscriptions, professional fees and capex accumulates.
• Cash impact: ITC accumulation of ~₹1.4 crore per quarter. Refund under Rule 89 is filed monthly. With clean documentation, refunds land in 45-60 days.
• E-invoicing: Triggered from day one because group turnover exceeds ₹5 crore.
• IMS workflow: Vendor invoices for rent, AWS, MS, professional fees flow through IMS; rejected lines are followed up the same week to keep GSTR-2B clean.

The result is a fully zero-rated export operation where almost all input tax flows back as cash within two months — exactly the cash cycle a captive's CFO needs.

SEZ, ISD and Multi-State Architecture

Telangana GST often involves more than one GSTIN. The structure should be decided at registration, not patched in later.

• SEZ units: Register on the standard GSTN portal and flag SEZ status. Supplies to and from the SEZ are zero-rated; separate invoicing series and distinct reporting in returns are mandatory.
• DTA units supplying SEZ: Treated as exports — file LUT and supply without IGST, or pay IGST and claim refund under Rule 96.
• ISD registration: Where head office in Hyderabad procures common services (audit, software, marketing) that benefit branches in other States, ISD distributes that ITC monthly to each branch.
• Cross-charge: For services performed by Hyderabad HO for branches (HR, finance, legal), cross-charge invoicing under Schedule I is mandatory — not optional.
• Multi-State expansion: Each State with a fixed establishment needs a separate GSTIN. We sequence Telangana first, then bolt on Karnataka, Maharashtra or Tamil Nadu as your team grows.

ISD vs cross-charge is the single most-misunderstood structure in Indian GST. Get it wrong at registration and you spend three years unpicking it during audits.

Where It Goes Wrong

These are the recurring mistakes we see when businesses register on their own or use a low-cost filer.

• Mismatched address proof: Lease names a previous tenant, electricity bill is in landlord's name, NOC is missing — the application is queried and the clock restarts.
• Wrong HSN / SAC selection: Selecting a generic SAC for a specific IT service or pharma product triggers later notices and refund delays.
• Missing LUT: Exports invoiced without LUT mean IGST should have been charged. Reversing this through refund and amendment is messy and time-consuming.
• Bank account not validated: Refunds and PMT-08 / DRC adjustments stall if the bank account on GSTN is not validated through name-PAN match.
• Biometric appointment missed: ARN sits in suspended state, application can be rejected, and re-filing means a fresh ARN and another verification cycle.
• Director / partner Aadhaar not linked to PAN: Aadhaar authentication fails silently and the file is parked indefinitely.
• SEZ flag missed at registration: Supplies into the SEZ get treated as domestic, IGST is wrongly charged, and the buyer's ITC chain breaks.
• E-invoicing ignored after ₹5 crore: Invoices without IRN are not valid for ITC at the buyer's end. Customers stop paying until reissued.

How to Get Started

Share a short brief on your business — entity type, expected turnover, sector, export markets and operating address in Telangana. We respond within a working day with a tailored document checklist, the right jurisdiction call, and a fixed quote covering registration and first-month configuration.

Once the pack is in, the GSTN application is filed within two working days. We track the file through ARN, biometric verification and final allotment, then hand you a configured GSTIN with LUT, e-invoicing and return calendar in place. You start invoicing the day GSTIN arrives, not three weeks later.
