India's export sector has seen explosive growth across both physical merchandise (apparel, engineering goods, agricultural produce, jewelry) and cross-border digital services (IT consulting, SaaS products, design, content, and freelancing). However, navigating Indian tax laws can feel daunting for new exporters.
A frequent point of confusion among aspiring exporters is: "If my export earnings are in foreign currency and my turnover is below ₹20 Lakhs, do I still need a GST number?"
1. Why GST Registration Is Mandatory for All Exporters
In domestic commerce, small micro-enterprises benefit from threshold exemptions: businesses trading in goods are exempt up to ₹40 Lakhs turnover, and service providers are exempt up to ₹20 Lakhs. However, these thresholds do not apply to exports.
Here is why under the law:
- Section 24(i) of the CGST Act: Persons making any inter-state taxable supply are required to be registered under GST mandatorily, without any turnover exemption.
- Section 7(5)(a) of the IGST Act: Supply of goods or services when the supplier is located in India and the place of supply is outside India is statutorily classified as an inter-state supply.
- Customs & ICEGATE Integration: The Directorate General of Foreign Trade (DGFT) and Indian Customs require your 15-digit GSTIN to be mapped with your Import Export Code (IEC) and Authorised Dealer (AD) Code on the ICEGATE electronic portal before any export shipment or bill of export can be cleared.
2. Understanding "Zero-Rated Supply" Under GST
Although GST registration is mandatory, Indian tax law ensures that Indian exporters remain globally competitive through the principle of Zero-Rated Supply under Section 16 of the IGST Act.
Zero-rated supply means the tax rate on the output supply is 0%. Furthermore, unlike "exempt" supplies where you cannot claim input tax credits, zero-rated export supplies allow you to claim a full refund of all taxes paid on inputs and raw materials.
The Two Routes for Exporting Under GST
| Feature | Route A: Export Under LUT (Without Tax) | Route B: Export With Payment of IGST |
|---|---|---|
| How It Works | File Form GST RFD-11 (LUT) once per year; export with 0% tax liability upfront. | Pay applicable Integrated GST (IGST) at the time of export and claim refund later. |
| Working Capital Impact | Zero capital locked up. Recommended for 99% of small businesses and MSMEs. | Requires upfront cash to pay 18% or 28% IGST on every invoice until customs refunds it. |
| Refund Mechanism | Refund of accumulated Input Tax Credit (ITC) on purchases via Form GST RFD-01. | Automatic refund of IGST paid via ICEGATE shipping bill data integration with GSTN. |
| Best Suited For | Service exporters, IT freelancers, MSME manufacturers, startups. | Large manufacturers with massive accumulated ITC that need rapid cash clearance. |
3. What Is a Letter of Undertaking (LUT) and How to File It
A Letter of Undertaking (LUT) is a declaration filed on the GST portal under Rule 96A of the CGST Rules, 2017. By filing an LUT, an exporter commits to completing the export of goods within 3 months of invoice issuance (or realization of foreign convertible currency within 1 year for service exports).
- Validity: An LUT is valid for an entire financial year (April 1 to March 31). You must renew it annually every March.
- Cost: Filing an LUT on the government GST portal is completely free.
- Instant Approval: Once submitted online with two independent witnesses, the GST portal generates an instant ARN (Application Reference Number) and acknowledgment.
4. Documents Required for Export GST Registration
To register your export firm on the GST portal (Form GST REG-01), keep the following documents ready:
- PAN Card: PAN of the Sole Proprietor, Partnership Firm, LLP, or Private Limited Company.
- Aadhaar Card: Linked to the applicant's mobile number for instant Aadhaar OTP authentication.
- Principal Place of Business Proof: Electricity bill, property tax receipt, and rent agreement along with a signed No Objection Certificate (NOC) from the owner.
- Bank Account Proof: Bank statement or cancelled cheque displaying the firm's name, account number, and IFSC code.
- Import Export Code (IEC): 10-digit alphanumeric code issued by the DGFT (mandatory for physical goods, recommended for services).
- Authorised Dealer (AD) Code: 14-digit code issued by your bank branch where foreign export remittances are received, necessary for customs registration.
- Partnership Deed / Certificate of Incorporation (COI): If applying as a partnership, LLP, or private company.

6. Service Exporters & Freelancers: Special GST Guidelines
If you are an Indian IT consultant, software engineer, digital marketer, or remote contractor working for clients in the US, UK, Europe, or Australia, you qualify as an exporter of services if you satisfy five statutory conditions under Section 2(6) of the IGST Act:
- The supplier of service is located in India.
- The recipient of service is located outside India.
- The place of supply of service is outside India (as per Section 13 of the IGST Act).
- Payment is received in convertible foreign exchange (or in Indian Rupees wherever permitted by RBI, e.g., Nepal/Bhutan or through approved Special Rupee Vostro Accounts).
- The supplier and recipient are not merely establishments of the same distinct entity.
