Software and SaaS companies face unique GST challenges, such as OIDAR classification, export zero-rating, and cross-border RCM. Proper compliance unlocks Input Tax Credit refunds and avoids penalties.

SaaS services fall under SAC code 9983 (IT services), attracting 18% GST on domestic supplies. Key sub-codes include 998313 (IT infrastructure), 998314 (IT solutions), and 998316 (IT system management).
Online Information Database Access or Retrieval (OIDAR) refers to automated internet-delivered services with minimal human intervention, typical of SaaS platforms.
SaaS providers must register if aggregate turnover exceeds ₹20 lakh (₹10 lakh in special states). Export-oriented firms register to claim ITC refunds despite zero-rated supplies.
Foreign SaaS serving Indian B2C customers requires Indian GST registration regardless of turnover. B2B uses the Reverse Charge Mechanism (RCM) by the Indian recipient.
For SaaS, the place of supply follows the recipient location:
Incorrect place of supply leads to the wrong tax type and ITC blocks.
Software/SaaS exports qualify as zero-rated supplies under LUT (Letter of Undertaking) without paying IGST upfront. Pay IGST and claim a refund, or supply under LUT.
Export invoices must mention “Supply meant for export” and include the recipient’s foreign address/bank details. No GST is charged on such invoices.
SaaS firms claim ITC on cloud hosting (AWS/Azure), office expenses, marketing services, and software licenses. Blocked credits apply to exempt supplies or personal use.
Export firms refund unutilized ITC accumulated from domestic inputs. Quarterly refund applications via the GST portal.
Issue GST-compliant invoices with SAC code, tax rate, place of supply, and GSTIN. E-invoicing mandatory for B2B if turnover > ₹5 crore (rising thresholds).
Foreign B2B invoices show “RCM applicable” – no GST charged by the provider.
| Return Type | Frequency | Due Date | Purpose |
| GSTR-1 | Monthly/Quarterly | 11th | Outward supplies (exports zero-rated) |
| GSTR-3B | Monthly/Quarterly | 20th/22nd/24th | Summary liability |
| GSTR-9 | Annual | Dec 31 | Annual return |
| Refund (Exports) | Quarterly | Before the next quarter’s end | ITC refund claim |
Timely filing prevents notices and ensures refund processing.
Indian SaaS firms pay RCM on imported services (foreign SaaS subscriptions) at 18% IGST. Self-invoice via GST portal and claim ITC if eligible.
| Pitfall | Impact | Solution |
| Wrong SAC code | Tax demand/ITC denial | Use 9983 series with CBIC clarifications |
| Export misclassification | Blocked refunds | Document foreign recipient + forex payment |
| RCM oversight | Penalties + interest | Monthly self-invoicing for imports |
| E-invoicing delay | Notices | Automate via IRP for threshold businesses |
