GST in Thiruvananthapuram: CGST, Kerala SGST, and IGST — FY 2025-26 Guide
Goods and Services Tax (GST) in Thiruvananthapuram, Kerala operates under a dual structure administered jointly by the Government of India and Kerala state government. Whether you are a business owner in the Technopark Phase I-III area, a consumer buying services inThiruvananthapuram, or a freelancer invoicing clients across India, the applicable GST component — CGST + Kerala SGST or IGST — depends on whether the supply is intra-state or inter-state. Kerala's stamp duty is 8% + 2% registration = 10% total — one of India's highest. Thiruvananthapuram houses India's premier space research facility (ISRO's VSSC/LPSC) — scientists and engineers here receive structured government pay scales with mandatory NPS contributions and among India's highest group mediclaim coverages. Kerala was the first state in India to implement a comprehensive e-Stamp duty system, fully digitizing property registration.
CGST vs Kerala SGST vs IGST: How It Works in Thiruvananthapuram
The fundamental rule:
- Intra-state supply (supplier and recipient both in Kerala): GST = CGST (central government) + Kerala SGST (Kerala government), each at half the total GST rate. On a Rs 1,00,000 invoice at 18%: CGST Rs 9,000 (9%) + Kerala SGST Rs 9,000 (9%).
- Inter-state supply (supplier in Kerala, recipient in another state, or vice versa): GST = IGST at the full rate. Same Rs 1,00,000 invoice at 18%: IGST = Rs 18,000 (18%), all to central government (then apportioned to destination state).
- Import of services: IGST under Reverse Charge Mechanism (RCM) — the recipient in Thiruvananthapuram pays GST to the government. Common for Thiruvananthapuram's businesses using foreign software, cloud services, or overseas consultants.
GST Rates Applicable to Thiruvananthapuram's Economy
The four main GST rate slabs apply uniformly across Thiruvananthapuram:

- Professional and consulting services: 18% GST under SAC 9983/9985. Freelancers and consultants in Thiruvananthapuram billing above Rs 20L/year must register for GST and charge 18% CGST + Kerala SGST on domestic invoices.
- Commercial property rent: If annual commercial rent in Thiruvananthapuramexceeds Rs 20L and the landlord is a GST-registered entity, 18% GST applies.

Input Tax Credit (ITC) for Thiruvananthapuram Businesses
GST-registered businesses in Thiruvananthapuram can claim Input Tax Credit on GST paid for goods and services used in their business. ITC rules in Kerala:
- CGST paid can offset CGST or IGST liability; Kerala SGST paid can offset Kerala SGST or IGST; IGST can offset any GST liability (IGST first, then CGST, then SGST).
- Conditions for ITC: Valid tax invoice, goods/services received, GST filed by supplier (reflected in GSTR-2B), and payment made to supplier within 180 days.
- ITC blocked items: Motor vehicles (for personal use), employee-related food and beverages, club memberships, health insurance for employees (unless mandatory under law), works contract for immovable property.
- ITC reconciliation: GSTR-2B (auto-populated) vs your purchase register must be reconciled monthly. Mismatch can lead to ITC disallowance and penalty — a critical compliance task for Thiruvananthapuram's MSMEs and large businesses alike.
GST Registration Threshold and Compliance for Thiruvananthapuram
GST registration is mandatory in Kerala when aggregate turnover exceeds:
- Rs 40 lakh/year for goods suppliers (Rs 20L for special category states — not applicable to Kerala).
- Rs 20 lakh/year for service providers.
- Any threshold for inter-state supplies, e-commerce operators, or businesses with taxable supplies despite low turnover.
Thiruvananthapuram freelancers and consultants in the IT/ITES sector who provide services to clients in other states must register for GST irrespective of turnover — even a single inter-state invoice triggers mandatory registration. Return filing: GSTR-1 (monthly/quarterly for outward supplies) + GSTR-3B (monthly summary + tax payment) + GSTR-9 (annual reconciliation). Businesses in Thiruvananthapuram with turnover above Rs 5 crore must file GSTR-1 monthly. Below Rs 5 crore, quarterly GSTR-1 filing is available under the QRMP scheme.
Composition Scheme: For Small Thiruvananthapuram Businesses
Small Thiruvananthapuram businesses with annual turnover below Rs 1.5 crore (goods) or Rs 50 lakh (services) can opt for the Composition Scheme — pay a fixed percentage of turnover as GST (1% for goods, 6% for services including restaurants) without ITC. Composition dealers cannot raise a tax invoice or collect GST from customers, and cannot supply inter-state. This suits small retailers, restaurants, and service providers inThiruvananthapuram's Technopark and Kazhakkoottam local markets who do primarily local business.
