Advance Authorization Scheme vs. IGST Exemption: Which One is More Beneficial?

If you are an exporter in India, working capital is likely your biggest concern. Every rupee stuck in taxes is a rupee less for your business growth.

Two powerful tools under the Foreign Trade Policy (FTP) help alleviate this burden: the Advance Authorisation Scheme (AAS) and the IGST Exemption on Imports. While both aim to reduce your upfront costs, they are not identical, and choosing the wrong one can accidentally block your refunds for months.

Many exporters assume that “Exemption” is always better than “Payment.” This is a myth.

The decision hinges on a complex GST rule known as Rule 96(10). This comprehensive guide discusses the difference between the two, the hidden traps of availing upfront exemptions, and how to choose the right strategy for your specific business model.

The Advance Authorisation Scheme is a duty exemption scheme issued by the DGFT (Directorate General of Foreign Trade). Its primary purpose is to allow the duty-free import of inputs (raw materials) that are physically incorporated into the export product.

• Basic Customs Duty (BCD): 100% Exemption.
• Social Welfare Surcharge (SWS): 100% Exemption.
• IGST (Integrated Goods & Service Tax): Exempted (subject to conditions).
• Anti-Dumping Duty/Safeguard Duty: Exempted.

You must fulfil an Export Obligation (EO). You are required to export finished goods worth at least 15% more than the value of the imported inputs within 18 months.

To alleviate working capital blockages, the government issued Notification No. 78/2017-Customs (for EOUs) and Notification No. 79/2017-Customs (for AA holders).

These notifications allow an Advance Authorisation holder to clear goods at Zero IGST at the port of import.

• The Immediate Benefit: No cash outflow at the import stage.
• The Trade-off: By utilising this specific notification, the exporter triggers the restrictions laid out in GST Rule 96(10).

This is the most important section for any finance manager or business owner.

Rule 96(10) of the CGST Rules stipulates that if an exporter has availed the benefit of certain notifications (specifically the upfront IGST exemption on imports), they are debarred from exporting goods on “Payment of IGST.”

Why is this a restriction? Under GST, there are two refund mechanisms for exporters:

• The “Rebate” Route (Export on Payment of IGST): The exporter pays IGST on the export invoice (using accumulated ITC) and receives an automated refund from Customs upon filing the EGM. This is the fastest refund mechanism (approx. 15-20 days).
• The “LUT” Route (Export without Payment of Tax): The exporter ships under a Letter of Undertaking (LUT) and must file a separate refund application (RFD-01) for unutilised Input Tax Credit. This process is manual, subject to audits, and significantly slower (3-6 months).

The Consequence: If you choose the IGST Exemption at the import stage, Rule 96(10) forces you into the slower LUT Route for your exports. You lose the flexibility of the automated rebate mechanism.

To determine the optimal route, one must compare the cost of capital against the administrative burden of refunds.

• Working Capital is Important: If the cost of capital (interest on OD/loans) is high, avoiding the upfront 18% payment is financially prudent.
• High Import Dependability: If the majority of your inputs are imported, you may not have enough domestic ITC to utilise for paying output tax, making the LUT route inevitable anyway.

• Refund Velocity is Priority: If you need refunds within 20 days to rotate funds, paying IGST at import (to avoid Rule 96(10)) allows you to use the fast-track export rebate route.
• Accumulated ITC: If you have significant domestic procurement, paying IGST on imports adds to your credit ledger, which can be rapidly liquidated by exporting on payment of tax.

Regardless of whether you choose to pay IGST or exempt it, the process to get the Advance Authorisation remains the same.

• Check SION: Verify if Standard Input Output Norms (SION) exist for your export product.
• Apply Online: File Form ANF 4B on the DGFT website.
• Link with Customs: Register the license at the port of registration.
• Execute Bond: Execute a Bond/LUT with Customs to cover the duty difference.
• Import: When filing the Bill of Entry:

• For IGST Exemption: Cite Notification No. 79/2017-Customs.
• For IGST Payment: Do not cite the IGST exemption notification; only claim the BCD exemption.

Managing the intersection of DGFT Policy and GST Law (like Rule 96(10)) requires dual expertise. A wrong notification number on your Bill of Entry can cost you lakhs in blocked refunds.

DGFT Guru helps you:

• Structure Your Imports: Decide whether to pay or exempt IGST based on a financial simulation.
• Obtain Licenses: Hassle-free issuance of Advance Authorisation and EPCG licenses.
• Compliance Audit: Ensure you are not violating Rule 96(10) while claiming benefits.

The choice between Advance Authorisation vs. IGST Exemption requires a holistic view of the company’s tax position. It is not a binary choice between saving tax or paying tax but a strategic decision between upfront liquidity (Exemption) and process efficiency (Payment).

Exporters must evaluate their domestic ITC accumulation and refund processing capabilities before opting for the exemption notification, ensuring they do not inadvertently trap themselves in a rigid compliance structure.

Que: Can I claim IGST exemption on some imports and pay IGST on others under the same Advance Authorisation?

Ans: Yes, technically you can. However, Rule 96(10) applies to the “Export Product.” If any raw material for that export product was imported using IGST exemption, the restriction on the export route comes in. It is safer to maintain a uniform policy for a specific export consignment.

Que: Is Basic Customs Duty (BCD) always exempted under Advance Authorisation?

Ans: Yes. The primary benefit of Advance Authorization is the exemption of Basic Customs Duty, SWS, and Anti-Dumping Duty. This remains valid whether you pay IGST or not.

Que: What happens if I accidentally export on payment of IGST after taking IGST exemption on imports?

Ans: This is a violation of Rule 96(10). You will receive a notice from the GST department asking you to repay the refunded amount along with interest. You must be very careful to link your import and export strategies.

Que: Does Rule 96(10) apply to Capital Goods (EPCG Scheme)?

Ans: No. The government clarified that the restriction under Rule 96(10) applies only to inputs (raw materials) and not to capital goods imported under the EPCG scheme. You can take an IGST exemption on machinery and still export on payment of IGST.

Que: How long is the Advance Authorisation valid?

Ans: The authorisation is valid for 12 months for making imports and 18 months for fulfilling the export obligation.
