Is GST registration mandatory for SaaS companies in India?

Yes, GST registration is mandatory for SaaS companies in India if your aggregate turnover exceeds ₹20 lakh (₹10 lakh for special category states). However, if you export SaaS services, you can register under GST even if your turnover is below the threshold to claim input tax credit on your business expenses.

How can SaaS companies export services without paying GST?

SaaS companies can export services without paying GST by filing a Letter of Undertaking (LUT) in Form GST RFD-11 on the GST portal. Once LUT is filed, you can export services at 0% IGST and claim refund of accumulated Input Tax Credit.

GST Compliance Guide for SaaS Companies in India (2026)

Q: What is the GST rate for SaaS services in India?

SaaS services in India are classified as Information Technology (IT) Services under HSN/SAC 998314 and attract 18% GST (9% CGST + 9% SGST for intra-state supplies, or 18% IGST for inter-state supplies). Exported SaaS services are zero-rated under GST.

The Indian SaaS industry is projected to reach $50 billion in revenue by 2030. But with growth comes regulatory complexity — especially under the Goods and Services Tax (GST) regime. For SaaS founders and finance teams, understanding GST compliance is not optional; it is critical to avoid penalties, interest charges, and business disruptions.

This comprehensive guide covers everything Indian SaaS companies need to know about GST compliance in 2026 — from registration and tax rates to export benefits and input tax credit.

Is GST Registration Mandatory for SaaS Companies?

Yes, GST registration is mandatory for SaaS companies in India if your aggregate turnover exceeds ₹20 lakh in a financial year (₹10 lakh for special category states like Jammu & Kashmir, Uttarakhand, etc.). However, even if your turnover is below this threshold, it is advisable to register voluntarily to claim Input Tax Credit (ITC) on business expenses like cloud infrastructure, software development tools, and office rent.

SaaS companies exporting services should also register under GST regardless of turnover to claim refunds of accumulated ITC.

GST Rate for SaaS Services

SaaS services in India are classified under SAC (Services Accounting Code) 998314 and attract 18% GST: 9% CGST + 9% SGST for intra-state supplies, or 18% IGST for inter-state supplies. This applies to:

Cloud-based software subscription fees
SaaS platform usage charges
Software maintenance and support contracts
API access and integration fees
Pay-as-you-go software usage billing

Important: Exported SaaS services are zero-rated under GST, meaning you can export services without charging GST and still claim refund of input tax credits.

Export of SaaS Services: LUT Filing and Benefits

Indian SaaS companies can export services without paying GST by filing a Letter of Undertaking (LUT) in Form GST RFD-11 on the GST portal. Here's the process:

File LUT before making any zero-rated exports — valid for one financial year
Export invoices must clearly state "Supply to SEZ" or "Export of Services"
Receive payment in convertible foreign exchange within the prescribed timeline
File refund claim for accumulated ITC in Form GST RFD-01

The benefit of LUT-based exports is significant: you avoid blocking working capital in GST payments while maintaining full ITC benefits on your domestic inputs.

Monthly GST Return Filing for SaaS Businesses

SaaS companies must file the following GST returns each month:

GSTR-1 (Due 11th): Details of outward supplies — all invoices raised during the month
GSTR-3B (Due 20th): Summary return with tax payment — aggregate of sales, ITC claimed, and net tax payable
GSTR-2A/2B (Auto-populated): Inward supply details auto-fetched from vendor filings — reconcile monthly

Late filing attracts a penalty of ₹50 per day (₹25 CGST + ₹25 SGST) plus 18% interest per annum on the tax amount. ComplianceRadar automates GST filing reminders and helps you track all regulatory deadlines.

Input Tax Credit (ITC) for SaaS Companies

SaaS companies can claim ITC on GST paid on business inputs, including:

Cloud infrastructure (AWS, Azure, GCP, DigitalOcean)
Software development tools and platforms
Office rent and utilities
Professional services (legal, accounting, consulting)
Marketing and advertising expenses

ITC must be claimed within the prescribed timelines. The GSTR-2B auto-populated statement must be reconciled with vendor GSTR-1 every month to ensure ITC eligibility.

Common GST Mistakes SaaS Companies Make

Wrong HSN/SAC Code: Using 9983 (IT Services) is correct; many mistakenly use 9984 (Telecommunications)
Not Filing LUT: Paying 18% GST on exports when it could be zero-rated with LUT
Missing ITC on Cloud Costs: Cloud infrastructure is a major ITC-eligible expense for SaaS companies
Late Filing: Daily penalties and interest add up quickly — use automated reminders
Not Reconciling GSTR-2B: Mismatches between GSTR-1 and GSTR-2B lead to ITC denial during audits
