✔ Your annual turnover exceeds ₹20 lakhs (₹10 lakhs in special category states)
✔ You provide services to clients in other states

Even if turnover is below ₹20L, many IT firms register voluntarily to:

🔹 18% GST
Applicable to:

- SaaS subscriptions
- App development
- Website development
- Maintenance contracts
You must charge 18% GST on invoices (unless export rules apply).
3️⃣ GST on Export of IT Services
If you provide services to clients outside India:
You can treat it as:
🔹 Zero-Rated Supply (Export)
Conditions:
- Client located outside India
- Payment received in foreign currency
- Proper documentation maintained
You can:

OR
✔ Pay GST and claim refund
Most IT exporters use LUT.
