Karnataka GST: IT services, SEZ billing, and the Bangalore commissionerates

Bangalore alone has three CGST commissionerates — Bangalore North, Bangalore South and Bangalore East — and the Karnataka State GST department runs parallel zones for SGST. Multi-office IT firms commonly hold one or two GSTINs in Karnataka (HSR, Whitefield or Electronic City) plus additional GSTINs in Hyderabad and Pune. HelloBooks supports multi-GSTIN per entity so the Bangalore registration files GSTR-1 with Karnataka POS for domestic sales, and zero-rated export invoices to the US or UK roll into the IGST table under LUT — the Letter of Undertaking is tracked with its expiry date so the annual renewal doesn't slip past the FY end.

SEZ billing is its own subsystem in Karnataka because Bangalore has three operating SEZs (Whitefield, Devanahalli and KSEZ in Devanahalli) and supplies to SEZ units are zero-rated under Section 16 of the IGST Act. HelloBooks tags SEZ customers separately, raises invoices with the SEZ flag in the GSTR-1 schema, and keeps the bond/LUT trail per shipment so refund-of-input-tax claims under Rule 89 are populated automatically when the quarterly refund window opens.

Karnataka Profession Tax, payroll and the CTD e-Sahyog portal

Karnataka Profession Tax (KPT) is levied under the Karnataka Tax on Professions, Trades, Callings and Employments Act, 1976. Employers register, deduct PT at the Karnataka slab (zero up to ₹15,000/month gross, ₹200/month above ₹15,000), and pay monthly by the 20th. HelloBooks runs KPT inside India payroll alongside PF (12% employer + 12% employee, ₹15,000 wage ceiling), ESIC (3.25% employer + 0.75% employee, ₹21,000 wage ceiling), gratuity accrual under the Payment of Gratuity Act, and FBP buckets that the employee chooses themselves through a self-service portal. Form 16 (annual) and Form 24Q (quarterly) generate from the same payroll engine.

The CTD Karnataka runs an e-Sahyog portal for taxpayer services — notice tracking, refund status, registration amendments — that sits alongside the central GST portal. HelloBooks doesn't try to scrape e-Sahyog (the CTD doesn't publish an API), but it does keep a unified compliance calendar so Karnataka-specific milestones (KPT monthly, PT annual return Form 4, KPTA amendment filings) sit next to central GST due dates in a single view.

Built for Karnataka startups, manufacturers, and traders

Bangalore startups care most about three things at the books level: ESOP accounting (Section 17(2)(vi) perquisite tax at exercise, deferred to sale for eligible startups under Section 80-IAC), capitalised software development under AS 26 / Ind AS 38, and clean revenue recognition under Ind AS 115. HelloBooks ships a chart of accounts pre-mapped to a SaaS template, runs revenue spreads on annual contracts, and keeps a cap-table view alongside the books for ESOP grant tracking. Manufacturers in Hubballi or Mysuru get the same BOM, work-order, job-work (Section 143) and capital-goods ITC flows used in Maharashtra. Mangaluru-Udupi traders get multi-warehouse with inter-state stock transfer on delivery challan + e-way bill — handy for moving goods between Karnataka and Kerala on NH-66.
