What Are GST Returns for SEZ?
GST returns for SEZ are periodic compliance filings submitted by Special Economic Zone units and developers under a separate GSTIN, reporting all zero-rated and taxable supplies, input tax credit claims, and IGST liabilities arising from their operations within the SEZ framework under the IGST Act, 2017.
All supplies to and from an SEZ are classified as inter-state transactions under Section 7(5)(b) of the IGST Act. Supplies for authorised operations are zero-rated under Section 16, allowing the supplier to either supply under LUT without IGST (and claim ITC refund) or pay IGST and claim refund.
SEZ units report supplies in Table 6A/6B of GSTR-1 with the correct SEZ flag. Refund claims are filed via Form RFD-01 with SEZ officer endorsement.
Key Terms for GST Returns for SEZ:
Zero-Rated Supply - Supply to SEZ for authorised operations at 0% GST under Section 16 IGST Act. Supplier claims ITC refund or IGST refund.
LUT (Letter of Undertaking) - Form GST RFD-11 filed annually to make zero-rated supplies without paying IGST upfront.
DTA (Domestic Tariff Area) - All areas outside SEZ. Supplies from SEZ to DTA are treated as imports attracting IGST and customs duties.
Form RFD-01 - GST refund application for IGST paid or unutilised ITC on zero-rated supplies. Requires SEZ officer endorsement.
Who Must File GST Returns for SEZ?
- SEZ Units: Manufacturing or service units operating within a notified SEZ with separate GST registration under Rule 8 CGST Rules
- SEZ Developers: Entities with Letter of Approval (LOA) for setting up or developing an SEZ
- DTA Suppliers to SEZ: Regular taxpayers making supplies to SEZ and claiming IGST or ITC refund under zero-rated provisions
- Co-developers: Infrastructure developers within an SEZ approved under the SEZ Act, 2005
Key rule: Under Rule 8 CGST Rules, every SEZ unit is deemed a separate business vertical. Separate GST registration is mandatory even if the same PAN already holds a DTA GSTIN in the same state. Nil returns required even with zero transactions.

How to File GST Returns for SEZ
Step-by-step process for SEZ GST return filing including separate registration, LUT, GSTR-1/3B classification, refund, and annual return.
Obtain Separate GST Registration
Submit Form GST REG-01 with the SEZ Letter of Approval (Form B or Form C) issued under Section 4(2) of the SEZ Act, 2005. Under Rule 8 CGST Rules, every SEZ unit is deemed a separate business vertical requiring distinct registration.
File LUT (Form RFD-11)
File LUT on the GST portal before the start of each financial year to make zero-rated supplies without payment of IGST. Navigate to Services > User Services > Furnish Letter of Undertaking. Renew annually.
File GSTR-1 by the 11th
Report SEZ supplies in Table 6A/6B with the correct SEZ flag. For DTA suppliers, mark supplies in B2B details with 'SEZ Supplies with Payment' or 'SEZ Supplies Without Payment'. Ensure e-invoice integration.
File GSTR-3B by the 20th
Declare zero-rated supply turnover in the appropriate table. Compute IGST liability or nil liability based on LUT usage. Reconcile ITC claims with GSTR-2B before submission.
Apply for Refund (RFD-01)
File Form RFD-01 on the GST portal. Without-payment route: claim ITC refund. With-payment route: claim IGST refund. Obtain SEZ officer endorsement confirming goods/services admitted for authorised operations. 90% provisional refund within 7 days.
File Annual Return (GSTR-9)
File by 31st December. Reconcile all monthly filings, ITC claims, and refund applications. Ensure no mismatch between GSTR-1, GSTR-3B, and GSTR-9 data for the financial year.
Documents Required for SEZ GST Filing
- SEZ Letter of Approval (Form B/Form C)
- Separate GSTIN registration certificate for the SEZ unit
- Valid LUT filed via Form GST RFD-11
- Tax invoices with SEZ supply declaration citing Section 16 IGST Act
- Bill of export (for goods) or proof of service receipt by SEZ
- SEZ officer endorsement for goods/services admitted for authorised operations
- E-way bills for goods movement exceeding Rs 50,000
- GSTR-2A/2B reconciliation report for ITC validation
- Declaration that SEZ unit has not claimed ITC on taxes paid by DTA supplier (for refund claims)
Common SEZ GST Filing Challenges
| Challenge | Impact | How Patron Accounting Solves It |
|---|---|---|
| Working Capital Blockage | DTA suppliers charge IGST instead of filing LUT, forcing SEZ unit to pay upfront and wait 30-60 days for refund | Patron coordinates with DTA suppliers to ensure LUT filing. Files for provisional 90% refund within 7 days as permitted under GST rules. |
| GSTR-1 vs GSTR-3B Mismatch | SEZ-specific flags and invoice details in GSTR-1 must exactly match GSTR-3B declarations. Mismatches cause refund rejections. | Automated reconciliation between GSTR-1, GSTR-3B, and GSTR-2B before every filing cycle to catch discrepancies. |
| Non-Authorised Operations | Zero-rated benefit does not apply for operations not covered in the Letter of Approval. IGST becomes chargeable per CBIC Circular 48/22/2018-GST. | Our CA team reviews Letter of Approval against each supply category and advises on correct GST treatment. |
| RCM Complications for SEZ | Confusion on whether SEZ units receiving RCM services under Section 9(3)/9(4) must pay IGST | SEZ units can procure RCM services without IGST if LUT is furnished (CBIC letter F.No. 334/335/2017-TRU). Patron tracks RCM for every inward supply. |
