GST Registration in Karnataka Just ₹499

Karnataka's GST state code is 29. All GSTINs issued to Karnataka businesses begin with 29 — from a Bengaluru startup to a Mysuru textile weaver. The state code is printed on every tax invoice and is what your buyers and clients use to verify your registration and claim ITC.

The CGST administration in Karnataka is organized under the Bengaluru CGST Commissionerate with multiple divisions. SGST (State GST) is administered by the Karnataka Commercial Taxes Department. Applications are filed centrally on the GST portal and auto-assigned to the appropriate officer based on your pincode.

Co-working spaces are extremely common in Bengaluru, and Karnataka GST officers have a clear expectation: NOC from the co-working operator specifically mentioning permission for GST registration, plus the operator's own EB bill as address proof. A co-working desk booking confirmation is not sufficient — the NOC must be on company letterhead.

Technology services dominate Karnataka's GST landscape. IT/software companies must select the correct SAC code at registration — 998314 for IT design and development, 998313 for software consulting, 998316 for cloud hosting. Wrong SAC assignment is the most common cause of GST notices for Karnataka tech companies.

Export of services (LUT route) applies to most Bengaluru SaaS and IT firms invoicing foreign clients. The LUT must be filed online before the first export invoice is raised. Without LUT, IGST at 18% must be paid upfront and then claimed as refund — a costly working capital tie-up that most early-stage companies cannot afford.

Outside Bengaluru, Mangaluru's seafood and cashew processors face a zero-rate export scenario on goods, which requires GST registration and a shipping bill linkage. Mysuru's silk textile weaving sector has a 5% GST on silk fabric and a 12% rate on processed silk garments.

The top mistake for Bengaluru tech companies is not filing LUT before invoicing overseas clients. Once IGST is charged on an export invoice, you have to either recover it from your client (bad for relationships) or claim a refund (takes 2-3 months). Filing LUT at registration time eliminates this entirely.

Another common issue is registering a co-working address without a proper NOC. Many Bengaluru co-working operators provide a standard membership agreement but not a specific GST/business registration NOC. This leads to queries and delays. We verify the NOC format before filing.

Karnataka has no state-specific GST compliance requirements beyond the central framework. GSTR-1 is due by the 11th of the following month, GSTR-3B by the 20th. For IT exporters who have filed LUT, GSTR-1 must correctly mark export invoices as zero-rated under LUT — not as exempt or nil-rated.

Annual LUT renewal is required before April 1st each year for businesses exporting services. Failure to renew means all export invoices from April onward will be treated as taxable until a fresh LUT is filed. We send reminders to all Karnataka IT clients in March each year.
