What is Zero-Rated Supply Under GST?
As per Section 16 of the IGST Act, 2017, zero-rated supply means any of the following supplies of goods or services or both:
- Export of goods — physical export out of India
- Export of services — supply to a recipient outside India with payment received in convertible foreign exchange
- Supply to a Special Economic Zone (SEZ) unit for authorised operations
- Supply to an SEZ developer for authorised operations
Important Clarification
Zero-rated is NOT a tax rate — it is a classification of supply. The effective tax rate is 0% (like exemption), but the supplier retains the right to claim and refund ITC, unlike exempt supplies.
Zero-Rated vs Exempt vs Nil-Rated GST
Many businesses confuse these three categories. Here's a clear comparison:
0% GST + ITC Allowed
Exports & SEZ supplies. Supplier can claim full ITC refund on inputs used.
0% GST – No ITC
Essential items like milk, education, health. ITC on inputs is blocked/reversed.
0% GST – No ITC
Items listed in Schedule I (e.g., salt, fresh vegetables). Similar to exempt in ITC treatment.
Updated Zero-Rated GST Items / Supplies for 2026
The following are the categories of zero-rated supplies as applicable in 2026:
| Category | Description | Conditions |
|---|---|---|
| Export of Goods | Physical export of any taxable goods out of India | Supported by shipping bill, bill of lading, customs clearance |
| Export of Services | Services provided to a person outside India | Payment received in foreign currency; recipient outside India |
| Supply to SEZ Unit | Goods/services supplied to SEZ unit for authorised operations | Endorsed copy of shipping bill / SEZ-specific documents |

Key Update for 2026
From October 2023, the definition of "export of services" was clarified — supplies to related parties abroad or between establishments of the same entity don't automatically qualify as exports unless they meet all conditions under Place of Supply rules and involve genuine foreign exchange inflow.
How to Make Zero-Rated Supply Under GST
A registered supplier making zero-rated supplies has two options:
Option 1: Export Under Bond/LUT (Without Paying IGST)
File a Letter of Undertaking (LUT) in Form GST RFD-11 at the beginning of each financial year. Supply goods/services without paying IGST and claim refund of accumulated ITC on inputs. This is the preferred route as it avoids cash flow blockage.
Option 2: Export on Payment of IGST and Claim Refund
Pay IGST on the export at the applicable rate and later claim a refund through the GST portal. This route involves upfront payment but may be simpler for occasional exporters.
ITC Refund Process for Zero-Rated Supplies
Exporters and SEZ suppliers can claim ITC refunds for:
- Refund of IGST paid on exports (auto-processed on filing GSTR-3B & GSTR-1)
- Refund of accumulated ITC on exports/SEZ supplies under LUT (via Form RFD-01)
The refund application must be filed within 2 years from the relevant date. Normally, refunds are processed within 60 days of acknowledgement.
