GST on Software Subscriptions and SaaS Tools: Examples, Documents and Common Mistakes

Domestic SaaS vs overseas SaaS

For an Indian SaaS vendor, the finance team generally validates tax invoice details, GSTIN, place of supply and ITC eligibility. For an overseas platform, the team must separately examine IGST Act definitions around import of services, place of supply and online information/database access or retrieval services. The same subscription line in the software ledger can therefore have different GST workflows.

Decision table for finance teams

Worked example

A Bengaluru-based company pays $1,200/month (about ₹1,00,000) for a US-based project-management SaaS tool, billed directly by the US entity with no Indian GST charged. Because the recipient is a registered Indian business and the supply is an import of service, the company must self-assess IGST at 18% (₹18,000) under reverse charge, pay it in cash via the GST portal, and only then claim it back as ITC - the foreign invoice alone, without the RCM payment challan, does not support an ITC claim. If the same tool were instead bought from an Indian reseller issuing a normal GST invoice, no RCM would apply - the company would simply verify the invoice, GSTIN and GSTR-2B reflection before claiming ITC in the ordinary way.

ITC and monthly close checks

• Match subscription invoices with active employees/projects.
• Block personal or non-business software costs from ITC.
• For import cases, pay RCM in cash before claiming eligible ITC.
• Keep annual list of software vendors with India/overseas classification.

Mistakes that create leakage

• Using a corporate card invoice without GSTIN and later trying to claim ITC.
• Missing RCM on overseas B2B subscriptions.
• Claiming ITC for entertainment or personal-use apps.
• Not updating vendor master when a foreign supplier starts issuing Indian GST invoices.
