GST on Software Subscriptions and SaaS Tools: Examples, Documents and Common Mistakes
SaaS subscriptions are now a routine finance expense, but GST handling depends on whether the supplier is in India or outside India, whether the buyer is registered, the place of supply and whether the purchase qualifies as an import of service.
Use the GST Rule 42 Common ITC Reversal Calculator to apply these points to your figures or facts.
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
| Scenario | GST control | Document to keep |
|---|---|---|
| Indian SaaS vendor with GST invoice | Verify tax invoice, GSTIN, place of supply and GSTR-2B visibility before ITC claim. | Invoice, contract, user/license list, business use approval. |
| Overseas SaaS vendor billed to Indian GSTIN | Evaluate import of service and reverse-charge treatment under IGST/CGST rules. | Subscription agreement, invoice, payment proof, RCM working. |
| Overseas app/tool used by unregistered/non-business user | Check OIDAR/non-taxable online recipient framework; do not apply B2B RCM mechanically. | Invoice, user status and payment data. |
| Mixed bundle: software + implementation + support | Split deliverables and tax treatment if contract allows/needs it. | Statement of work and invoice break-up. |

ITC and monthly close checks
- Match subscription invoices with active employees/projects.
- Block personal or non-business software costs from ITC.
