A Letter of Undertaking (LUT) allows exporters to supply goods or services without paying IGST upfront. This enables registered exporters to make zero-rated supplies without an immediate tax payment, subject to the applicable GST requirements.
The LUT is filed electronically in Form GST RFD-11 through the GST portal and is valid for the applicable financial year. Exporters must submit a fresh LUT at the beginning of each financial year. Following a GST LUT checklist can help exporters complete renewal and maintain compliance on time.
Benefits of Exporting Under LUT
1. No Upfront IGST Payment
Exporters can ship goods or provide services without paying IGST at the time of export.
2. Improved Cash Flow
Because there is no need to pay IGST initially, businesses can retain their working capital for regular operational requirements. This makes LUT a useful option for exporters seeking better cash-flow management.
3. Lower Refund Dependency
Exporters operating under LUT do not have to wait for an IGST refund for every export transaction. This can make the overall GST process more convenient and reduce refund-related procedures.
4. Smoother Export Process
Since exports are not dependent on receiving an IGST refund, businesses can manage their export transactions more efficiently.
5. Ideal for Regular Exporters
LUT is generally a convenient option for businesses that regularly export goods or services and want to avoid making upfront IGST payments.
Let’s Understand the Limitations of LUT
When comparing GST LUT with the IGST refund option, exporters should also consider the limitations associated with filing an LUT.
1. Annual Renewal
An LUT remains valid for one financial year, so exporters need to submit a fresh LUT each year.
2. Compliance Requirements
Exporters must follow the applicable GST provisions and maintain accurate export records and supporting documents. Proper documentation is important because using an LUT can also affect the invoicing and accounting treatment of export transactions.
3. Export Conditions Must Be Met
The conditions attached to exports under LUT must be fulfilled. If goods are not exported within three months from the invoice date, unless an extension is permitted by the authorities, or payment for exported services is not received within the prescribed period, the exporter may become liable to pay the applicable tax along with interest.
What is an IGST Refund?
Under the IGST refund mechanism, an exporter first pays IGST on the export transaction and subsequently claims a refund of the tax paid.
For exports of goods, the shipping bill generally serves as the refund application once the prescribed GST and customs requirements are satisfied. For exports of services, the exporter must follow the refund procedure prescribed under GST law.
Therefore, businesses often compare GST LUT and IGST Refund to identify the option that best fits their cash-flow and compliance requirements.
Benefits of IGST Refund
The IGST refund method offers several benefits:
1. Suitable for Businesses Not Using LUT
Exporters that do not choose the LUT route can export by paying IGST and subsequently claim a refund.
2. Defined Refund Process
GST law provides a prescribed mechanism for exporters to claim a refund of the IGST paid on eligible exports.
3. Zero-Rated Export Benefit
Through the refund mechanism, exporters can ultimately obtain the benefit of zero-rated supplies.
4. Useful for Certain Business Situations
Depending on the nature of the business, cash-flow position, and compliance preferences, some exporters may find the IGST refund route more suitable.
Challenges of IGST Refund
When comparing LUT with the IGST Refund option, businesses should keep the following challenges in mind:
1. Working Capital Blockage
Since IGST has to be paid upfront, the business’s working capital may remain blocked until the refund is received.
2. Refund Processing Time
While GST law specifies timelines for processing refunds, verification and other procedures may cause the actual processing time to vary depending on the claim.
3. Documentation Requirements
Proper GST returns, shipping information, and supporting documents must be maintained to ensure the refund claim is processed successfully.
4. Reconciliation Requirements
Differences or mismatches between GST returns and export-related information can result in delays in receiving the refund.
GST LUT vs IGST Refund: Key Differences
| Particulars | LUT | IGST Refund |
|---|---|---|
| Tax payment at export | Not required | Required |
| Working capital impact | Low | Higher |
| Refund dependency | No IGST refund required | Refund needs to be claimed |
| Cash flow management | Better | May be affected |
| Compliance process | LUT filing required | Refund claim procedure required |
| Suitable for | Regular exporters | Exporters choosing the tax-payment route |
Understanding these differences can help exporters make an informed choice between GST LUT and IGST Refund.
GST LUT vs IGST Refund: Which is Better?
When comparing GST LUT with IGST Refund, many exporters prefer LUT because it eliminates the need to pay IGST upfront and helps preserve working capital.
LUT is generally suitable for businesses that regularly export goods or services and want better cash-flow management. On the other hand, the IGST refund route may work for exporters who prefer to pay tax at the time of export and claim the applicable refund later. Businesses can also compare GST LUT vs Bond to understand the other mechanism available under GST.
The most suitable option depends on factors such as export volume, cash-flow requirements, compliance capabilities, and business preferences.
Factors to Consider Before Choosing
Before selecting between GST LUT and IGST Refund, businesses should consider the following:
1. Cash Flow Requirements
Businesses that want to avoid blocking working capital may find LUT more convenient.
2. Export Volume
Regular exporters may prefer LUT because it avoids the need to repeatedly claim refunds for IGST paid on exports.
3. Compliance Management
Businesses should evaluate their ability to maintain accurate records and fulfill the applicable GST requirements under either option.
4. Operational Preferences
The decision may depend on whether the business prefers to export without paying IGST upfront or pay IGST and claim the refund afterward.

Both options are recognized under GST law and allow exporters to benefit from zero-rated exports. Businesses should carefully assess their financial and operational requirements before selecting the most appropriate option between GST LUT and IGST Refund.
