Major Exporter Scheme (MES): The Definitive Guide for Cash-Flow-Hungry Exporters

Last Updated: June 2026

The Major Exporter Scheme (MES) is a GST scheme run by IRAS that suspends the 9% import GST for businesses that import and export goods on a large scale. Instead of paying GST at the point of import and waiting to claim it back in your next GST return, an approved MES business pays nothing upfront on qualifying imports. For a trader moving high volumes through Singapore Customs, that suspension frees up working capital that would otherwise sit with IRAS for weeks.

This guide explains what MES does, the cash-flow problem it solves, who qualifies, how to apply (including the self-review IRAS expects), how MES sits alongside the Import GST Deferment Scheme and Singapore Customs permits, and the responsibilities and pitfalls every MES holder should know.

Key Takeaways

• The Major Exporter Scheme is an IRAS GST scheme that suspends import GST so approved businesses do not pay 9% GST upfront when they import goods.
• To qualify, you must be GST-registered, run an active business with good compliance and internal controls, and have zero-rated supplies over 50% of total supplies, or zero-rated supplies worth more than S$10 million.
• The cash-flow gain is direct: instead of paying 9% at customs and waiting to reclaim it, you pay S$0 on qualifying imports.
• Applying requires a self-review of your GST controls, usually the Assisted Self-help Kit (ASK), before IRAS approves or renews the scheme.
• MES suspends import GST; the related Import GST Deferment Scheme (IGDS) instead defers it to your GST return.
• MES is granted for a limited period (commonly 3 to 5 years), must be renewed, and IRAS can revoke it for non-compliance.

What Is the Major Exporter Scheme?

The Major Exporter Scheme is a GST facilitation scheme administered by IRAS. It is designed for businesses whose trade is mostly export-driven, where charging GST on imports only to refund most of it later creates a needless cash drag.

Under normal GST rules, when goods enter Singapore the importer pays GST to Singapore Customs at the prevailing rate of 9%. A GST-registered business then claims that amount back as input tax in its GST return. The money is recovered, but only after a delay, and the larger the import volume the larger the sum locked away in the meantime.

MES removes that step for approved businesses. GST on imports is suspended, so no GST is paid at the point of import. The same suspension applies to goods removed from a Zero-GST warehouse or a licensed warehouse under MES. You still report the imports in your GST return, but there is no cash outlay to recover. For a high-volume exporter, this turns a recurring cash-flow problem into a non-event.

What Cash-Flow Problem Does MES Solve?

Picture an electronics distributor that imports S$5 million of goods a quarter and exports most of it. Without MES, that business pays roughly S$450,000 in import GST at customs each quarter, then waits until its GST return to recover it. That is a large, repeating sum tied up purely as a timing difference.

With MES, the import GST is suspended, so the upfront cost is zero. The working capital that would have funded the GST sits in the business instead, available for inventory, payroll, or growth. The chart below shows the upfront import GST cost on a single S$1 million shipment, with and without the scheme.

The saving is a timing benefit, not a reduction in tax owed. You are not paying less GST overall; you are simply not lending the GST amount to the system and waiting for it back. For a business with thin margins and heavy import flows, that timing difference is often the single biggest cash-flow lever available, and it pairs well with disciplined accounting and compliance habits.

Who Qualifies for the Major Exporter Scheme?

MES is not open to every importer. IRAS sets eligibility around how export-heavy your business is and how well you run your GST function. To qualify, your business must:

• Be GST-registered in Singapore. If you have not yet crossed or elected into registration, start with the GST registration threshold rules first.
• Be an active business that imports goods in the course of its trade.
• Maintain good compliance with IRAS and have sound internal controls over GST accounting and record-keeping.
• Meet the export-volume test: zero-rated supplies (exports and international services) must be more than 50% of total supplies, OR the value of zero-rated supplies must be more than S$10 million.

The two-limb export test matters. A smaller exporter with a strongly export-tilted sales mix can qualify through the 50% ratio, while a very large trader can qualify on the S$10 million value even if domestic sales are also sizeable. Either route works, but you must be able to evidence the figures from your accounting records, so clean books are not optional.

Why internal controls weigh so heavily

Because MES lets goods enter without GST being collected, IRAS gives the scheme to businesses it trusts to self-account accurately. Weak controls, late filings, or a history of GST errors will count against an application. This is why the scheme suits businesses that already treat GST as a managed process rather than an afterthought, the same standard a good accounting firm builds into your monthly close.

How Do You Apply for the Major Exporter Scheme?

Application is made to IRAS, but the centrepiece of a credible application is a self-review of your GST controls. IRAS expects you to complete the Assisted Self-help Kit (ASK), or to be on the Assisted Compliance Assurance Programme (ACAP), to demonstrate that your GST processes are sound before the scheme is granted.

The practical sequence usually looks like this:

1. Confirm you meet the eligibility tests, especially the zero-rated supplies threshold, from your actual figures.
2. Complete the ASK self-review, which walks through GST registration, filing, and record-keeping controls and surfaces gaps to fix first.
3. Submit the MES application to IRAS with the supporting self-review.
4. Address any IRAS queries, then implement the scheme once approved, ensuring your customs declarations reflect MES status correctly.

The ASK is not a tick-box exercise. It often reveals process gaps, such as weak documentation for zero-rated exports, that would otherwise resurface in an audit. Fixing them before you apply both strengthens the application and improves your wider GST compliance. Businesses still getting set up should ensure they have first registered the company and sorted a corporate bank account so trade and tax records line up cleanly from day one.

How Does MES Work With Customs Permits and Other Schemes?

MES does not replace the customs process; it changes how GST is treated within it. When you import under MES, the GST suspension must be declared correctly on the import permit obtained through Singapore Customs. The Singapore Customs guidance on the Major Exporter Scheme sets out how MES interacts with import and removal permits, so the declared GST treatment matches your IRAS approval.

It also helps to know where MES sits among related schemes:

• Import GST Deferment Scheme (IGDS): Where MES suspends import GST entirely, IGDS defers it to your GST return. Under IGDS you still account for the import GST, but you pay and claim it in the same return rather than at customs, removing the upfront cash outlay through a deferral rather than a suspension.
• Zero-GST and licensed warehouses: Goods stored in these facilities can be moved without triggering GST, and MES extends the same no-upfront-GST treatment when such goods are removed under the scheme.

For most pure exporters, MES is the cleaner fit because it removes the GST step entirely. IGDS can suit businesses that import heavily but sell more domestically and so do not meet the MES export test. An accounting firm familiar with the YA 2026 tax landscape can map which scheme matches your trade profile.

What Are an MES Holder’s Responsibilities, and How Is It Renewed?

Approval is the start, not the finish. As an MES holder you must keep accounting and shipping records that support every suspended import, continue to meet the eligibility tests, file accurate GST returns on time, and apply the suspension only to imports that genuinely qualify. The privilege rests on continued good compliance.

MES is granted for a limited period, commonly 3 to 5 years, and must be renewed before it lapses. Renewal typically requires a fresh self-review, so the ASK discipline becomes a recurring habit rather than a one-off. IRAS monitors MES holders and can review, suspend, or revoke the scheme where it finds non-compliance, such as inaccurate returns or a drop below the eligibility thresholds. This matters for foreign-owned companies and groups where cross-border flows and related-party pricing add complexity to the GST position.

Common compliance pitfalls

A few errors recur among MES holders:

• Applying GST suspension to imports that do not qualify, for example goods bought for purely domestic onward sale outside the scheme’s intent.
• Letting zero-rated supplies fall below the threshold without flagging that eligibility may now be at risk.
• Poor documentation of exports, so the zero-rating that underpins MES eligibility cannot be substantiated in an audit.
• Missing the renewal window or skipping the self-review, which can interrupt the suspension.

These are the same record-keeping fundamentals that protect any GST position, and they are far cheaper to maintain than to repair after an IRAS query. Online sellers shipping across borders, for instance through an e-commerce business, should be especially careful that their platform and logistics records line up with their GST treatment.

Frequently Asked Questions

What is the Major Exporter Scheme in Singapore?

The Major Exporter Scheme is a GST scheme administered by IRAS that suspends import GST for businesses that import and export goods substantially. Instead of paying GST at the point of import and reclaiming it later, an approved MES business pays no GST upfront on qualifying imports. The scheme is built to ease the cash-flow burden that import GST creates for high-volume, export-driven traders.

Who qualifies for the Major Exporter Scheme?

To qualify, a business must be GST-registered, be an active importing business with good compliance and sound internal controls, and meet the export-volume test. That test is met if zero-rated supplies (exports and international services) are more than 50% of total supplies, or if the value of zero-rated supplies is more than S$10 million. The business must be able to evidence these figures from its accounting records.

How does MES improve cash flow?

MES improves cash flow by removing the upfront 9% import GST that would otherwise be paid at customs and recovered later. On a S$1 million shipment, that is S$90,000 that stays in the business rather than being paid to IRAS and reclaimed weeks afterward. The benefit is a timing one: you do not pay less GST overall, but you stop lending the GST amount to the system between import and refund.

How do I apply for the Major Exporter Scheme?

You apply to IRAS, and the application must be supported by a self-review of your GST controls, usually the Assisted Self-help Kit (ASK) or participation in ACAP. Confirm you meet the eligibility tests, complete the ASK to surface and fix any control gaps, then submit the MES application with the supporting review. Once approved, make sure your customs declarations reflect the MES suspension correctly.

What is the difference between MES and the Import GST Deferment Scheme?

MES suspends import GST entirely, so no GST is paid at the point of import. The Import GST Deferment Scheme (IGDS) instead defers the import GST to your GST return, so you account for and settle it in the return rather than at customs. Both remove the upfront cash outlay, but MES does so by suspension while IGDS does so by deferral, and IGDS can suit importers who do not meet the MES export threshold.

How long does MES last and can it be revoked?

MES is granted for a limited period, commonly 3 to 5 years, and must be renewed before it expires, usually with a fresh self-review. IRAS monitors MES holders and can review, suspend, or revoke the scheme for non-compliance, such as inaccurate GST returns, applying the suspension to imports that do not qualify, or falling below the eligibility thresholds. Maintaining accurate records and timely filings keeps the status secure.
