In Singapore, the Major Exporter Scheme (MES) is an IRAS GST scheme that suspends the 9% import GST on non-dutiable goods for businesses that import and export on a large scale. Instead of paying GST at the point of import and waiting to claim it back in your GST return, an approved MES business pays nothing upfront on those imports. For a trader moving high volumes through Singapore Customs, that frees up working capital that would otherwise be tied up for weeks or months, until the GST is recovered through a GST return.

To qualify, more than half of your supplies, or more than S$10 million a year, must be zero-rated, and, unless you are on IRAS’s ACAP programme, you must submit an ASK annual review certified by an SCTP-accredited GST practitioner. You need that certified review when you apply, and again each time you renew.

Key Takeaways

  • MES suspends the 9% import GST on non-dutiable goods, and on goods removed from a Zero GST warehouse, so approved businesses pay nothing upfront. It is a cash-flow benefit, not a tax saving.
  • To qualify, you must be GST-registered and solvent, have zero-rated supplies of more than 50% of total supplies or more than S$10 million over 12 months, have good compliance records with IRAS and Singapore Customs, and submit a certified ASK review (unless you are on ACAP).
  • You apply with Form GST F10 and the certified ASK. IRAS says it will decide within one month, and a first approval usually lasts 3 years.
  • To renew, you submit Form R1 and a fresh certified ASK by the date in IRAS’s invitation letter. MES stays valid while IRAS decides, and a renewal usually lasts another 5 years.
  • The ASK review must be done, or certified, by an SCTP Accredited Tax Practitioner (GST) or Accredited Tax Advisor (GST), in-house or external.
  • Using your MES status for goods that belong to a related company, a local supplier or your staff is an offence, and IRAS can revoke the scheme and recover the GST.

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 paying GST on imports only to claim most of it back 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 of non-dutiable goods 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. MES does not change how you sell: if you supply the goods in Singapore, you still charge GST on that sale at the prevailing rate.

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, and that cash stays available for inventory, payroll or growth. The chart shows the same effect on a single S$1 million shipment.

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?

IRAS’s e-Tax Guide on MES sets out the qualifying conditions, and says they have the force of law. You must meet all of them, and keep meeting them while you hold the scheme.

Condition What IRAS requires
GST-registered Your business is registered with IRAS for GST.
Active and solvent Not under bankruptcy, liquidation, receivership or judicial management.
Imports for the business You import goods in the course of your business.
Zero-rated supplies More than 50% of total supplies, or more than S$10 million, over 12 months: your last financial year, or any 12 consecutive months within the past 18. Zero-rated supplies include exports of goods and international services.
Internal controls and records Good internal controls and proper accounting records.
Record with Singapore Customs A good compliance record with Singapore Customs.
Record with IRAS GST and income tax returns filed, and GST, income tax, property tax and withholding tax paid, on time.
Certified ASK review An ASK declaration certified by an SCTP Accredited Tax Practitioner (GST) or Accredited Tax Advisor (GST), unless you are on ACAP.
Other conditions Any other conditions IRAS imposes from time to time.

Two further points. If you make exempt supplies, they must stay within the de minimis limit: on average no more than S$40,000 a month and no more than 5% of your total supplies. And even if you meet every condition, IRAS may ask for a guarantee from a financial institution, or refuse an application to protect revenue.

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 way, you must be able to evidence the figures from your accounting records. If you have not yet registered for GST, start with the GST registration threshold rules.

Because MES lets goods enter without GST being collected, IRAS gives the scheme to businesses it trusts to account accurately. Weak controls, late filings or a history of GST errors count against an application. The scheme suits businesses that already treat GST as a managed process rather than an afterthought.

How do you apply for the Major Exporter Scheme?

You can apply once you are GST-registered and have started trading. The sequence is:

  1. Check your figures. Use a 12-month period: your last financial year, or any 12 consecutive months within the past 18. Confirm the zero-rated test and the exempt supplies limit from your actual records.
  2. Complete the ASK annual review and have it certified (see who can certify it). IRAS may ask for the working templates behind it, so keep them.
  3. Submit Form GST F10 with your 12-month trading figures in Singapore dollars and the certified ASK declaration form.
  4. Provide a guarantee if IRAS asks for one. Digital guarantees (eGuarantees) can be bought from participating financial institutions.
  5. Wait for the outcome. IRAS says it will tell you within one month. An approval usually lasts 3 years, until IRAS writes to say your MES is due for review.

A newly incorporated business, or one changing its business activity, can apply on a 12-month projection instead, explaining the basis for it. IRAS may then require a guarantee, and you must send the actual figures and the certified ASK later, by the date IRAS sets.

Once approved, you can authorise up to 20 declaring agents, such as freight forwarders, on myTax Portal to clear goods for you. MES is approved for your business, not for the forwarder, which clears MES goods only as your authorised agent. The air express companies DHL Express, FedEx and UPS can also clear goods under your MES status without being authorised, unless you tell them in writing not to. You are accountable for every permit declared under your MES status. Each MES import needs an ME permit from Singapore Customs.

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 IRAS audit. Fixing them before you apply strengthens the application and improves your wider GST compliance.

How does MES renewal work?

Renewal follows a fixed path. IRAS’s MES page sets it out:

  1. IRAS sends a renewal invitation when your MES is due for review, if you still meet the conditions. If you do not, you are not invited, and IRAS tells you so.
  2. You submit Form R1 online through myTax Portal, with a fresh certified ASK, by the due date in the letter.
  3. Your MES stays valid while IRAS reviews the renewal, and IRAS tells you the outcome in writing.
  4. IRAS reviews whether a guarantee is still needed, and tells you if it is.
  5. A successful renewal usually lasts another 5 years, compared with 3 years for a first approval.

What is the ASK annual review, and who can certify it?

ASK stands for Assisted Self-help Kit, IRAS’s self-assessment package for GST-registered businesses. The GST ASK review that MES requires is the kit’s annual review section: a structured check of your past GST returns against your records. You need a certified one when you apply and each time you renew, and IRAS requires one for other GST schemes too, such as IGDS. It can be done in one of two ways:

How the ASK review is done Who signs off
Performed by an SCTP Accredited Tax Practitioner (GST) or Accredited Tax Advisor (GST), who can be your own staff or an external adviser Your business and the practitioner both complete IRAS’s ASK declaration forms
Performed by your own team and certified by an external practitioner, who follows IRAS’s certification procedures Your business completes the declaration forms, and the practitioner completes the certification report, listing any exceptions found

The five steps of the ASK annual review

IRAS’s ASK Annual Review Guide sets out five steps:

  1. Review the GST declarations for your past financial year.
  2. Select returns covering at least 3 consecutive months.
  3. For every figure in those returns, review the listing behind it, select samples and check their supporting documents.
  4. Compare your financial statements with your GST declarations for the same year.
  5. Quantify any errors and submit your findings.

One of the checks (Step 3E) covers imports with GST suspended under MES, so the review tests exactly the records the scheme depends on.

If the review finds errors

Correct them with a GST F7, on a consolidated annual basis, or in your next GST return if they fall within IRAS’s concession for small errors. Some common errors fall within IRAS’s separate ASK administrative concessions, under which past returns need not be amended; you self-assess these against IRAS’s published list. IRAS waives the 5% late payment penalty if you disclose the errors within one year from the statutory filing date of the last GST return in the financial year you reviewed, provided the conditions of its Voluntary Disclosure Programme are met. For a financial year ending 31 December 2025, that means by 31 January 2027. After that, the penalty is no longer waived, but IRAS imposes a reduced penalty of 5% of the tax undercharged, if the programme’s conditions are met. IRAS can still widen its own checks, and errors it finds itself do not qualify for the programme.

On ACAP instead?

Businesses accepted into IRAS’s Assisted Compliance Assurance Programme (ACAP) do not need the certified ASK declaration for MES. If they withdraw from ACAP, or fail to obtain ACAP status, they must perform the ASK review and submit the certified declaration within 6 months of the withdrawal or of IRAS’s notice. A business that already holds ACAP status submits its Post ACAP Review (PAR) declaration (GST F28) or applies to renew ACAP (GST F29) instead. If it is under MES and not renewing ACAP, it must have a second PAR performed or certified by an SCTP Accredited Tax Practitioner (GST) or Accredited Tax Advisor (GST), and submit GST F28A. IRAS also lists auto-renewal of GST schemes such as MES, where applicable, among the benefits of ACAP status.

How does MES work with ME permits and other schemes?

MES does not replace the customs process; it changes how GST is treated within it. An ME permit is the import permit you take up with Singapore Customs for goods imported under MES: a Customs In-Non-Payment permit with the place of receipt code ME. It keeps the declared GST treatment in line with your IRAS approval. You can declare it yourself through TradeNet, once your Customs account is activated, or through your declaring agents. The Singapore Customs guidance on the Major Exporter Scheme explains how MES works with import and removal permits.

In your GST return, MES imports go in Box 5 (taxable purchases) and Box 9 (goods imported under MES or other approved schemes), backed by valid ME permits and shipping documents. Because no GST was paid on those imports, you claim no input tax on them.

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. Approved businesses pay the import GST when their monthly GST return is due, instead of at customs, and claim it as input tax in the same return.
  • Zero GST and licensed warehouses: import GST on goods stored in these warehouses is suspended while they stay there, but it becomes payable when the goods are removed for local consumption. MES suspends the GST on that removal too, so an MES business pays nothing upfront when it takes such goods out under the scheme.

For most pure exporters, MES is the cleaner fit because it removes the upfront GST payment entirely. IGDS can suit businesses that import heavily but sell more domestically, and so do not meet the MES export test. Both IGDS and MES applications need an ASK review.

What are an MES holder’s responsibilities?

Approval is the start, not the finish. As an MES holder, you must keep accounting and shipping records that support every suspended import, keep meeting the qualifying conditions, file accurate GST returns on time, and use the scheme only for purposes IRAS allows. IRAS can revoke the scheme at any time if you stop meeting a condition, and if your business changes so that you no longer qualify, you must tell IRAS. This matters especially for foreign-owned companies and groups, where cross-border flows add complexity.

Common compliance pitfalls

  • Using MES for goods that are not yours. You may import your own goods, goods of an overseas principal you act for as its section 33(2) or 33A agent, and goods you sent abroad for value-adding work and re-import for a customer, where the section 33B conditions are met. A GST-registered overseas principal must apply for MES in its own name, even if you act as its section 33(1) agent. IRAS’s examples of abuse include importing goods that belong to a related company or business partner, goods still owned by a local supplier, and the personal items of staff or directors. It is an offence: IRAS can impose penalties, revoke your MES and recover the import GST.
  • Using MES for the wrong goods. It cannot be used for investment precious metals, or for goods used to make exempt supplies.
  • Not checking the permits taken up under your MES status. IRAS suggests reconciling the permit listings from your declaring agents, the air express companies’ monthly Inward Summary Reports and TradeNet against your own import records, to confirm your status was used only as IRAS allows.
  • Treating MES as transferable. If you sell the business, the buyer cannot use your MES status and must apply in its own name.
  • Getting the GST return wrong, for example leaving MES imports out of Box 9, or claiming input tax on imports where the GST was suspended.
  • Letting zero-rated supplies slip below the threshold without checking whether you still qualify, and telling IRAS if you do not.
  • Poor documentation of exports, so the zero-rating that underpins your eligibility cannot be substantiated in an audit.
  • Missing the renewal due date, or sending Form R1 without a certified ASK, which puts the renewal at risk.

If you run an e-commerce business that ships across borders, make sure your platform and logistics records line up with your GST treatment. If an IRAS query arrives about any of this, our guide to IRAS letters and audits explains what each type of letter means.

How we help with MES and ASK reviews

Excellence Singapore Group’s tax team, which brings accreditation from the Singapore Chartered Tax Professionals (SCTP) in both income tax and GST, handles GST schemes and ASK reviews. We perform and certify ASK Annual Reviews, including those IRAS requires for MES applications and renewals. For an MES application or renewal:

  1. We check whether you qualify, from your actual figures, including the zero-rated test and the exempt supplies limit, and whether IGDS would suit you better if you do not.
  2. We perform or certify the ASK annual review, and help you fix the process gaps it finds, so the same errors do not recur.
  3. We prepare the GST F10 application, or the Form R1 renewal, with the certified declaration.
  4. We correct any errors the review finds through the right route, and tell you whether IRAS’s penalty waiver can still apply.
  5. We keep your GST returns MES-ready afterwards, including the Box 9 reporting.

Fees are quoted after we review your GST returns and records. If IRAS’s renewal letter has arrived, send it to us early, with its due date: the certified ASK must go in with Form R1 by then.

Frequently Asked Questions

What is the Major Exporter Scheme in Singapore?

It is an IRAS GST scheme that suspends the 9% import GST on non-dutiable goods for businesses that import and export substantially. Instead of paying GST at the point of import and claiming it back later, an approved MES business pays nothing upfront on those imports, which eases the cash-flow strain of import GST for export-driven traders. Goods supplied in Singapore are still charged GST as usual.

Who qualifies for the Major Exporter Scheme?

A GST-registered, solvent business that imports goods for its business, and whose zero-rated supplies are more than 50% of total supplies, or more than S$10 million, over a 12-month period. It must also keep good internal controls and good compliance records with IRAS and Singapore Customs, and submit an ASK review certified by an SCTP-accredited GST practitioner, unless it is on ACAP.

How does MES improve cash flow?

MES removes 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 instead of being paid at import and claimed back afterwards. The benefit is one of timing: 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?

Submit Form GST F10 to IRAS with your trading figures for a 12-month period and an ASK declaration certified by an SCTP Accredited Tax Practitioner or Accredited Tax Advisor (GST), unless you are on ACAP. IRAS may ask for a guarantee, and says it will give its decision within one month. A first approval usually lasts 3 years.

How do I renew the Major Exporter Scheme?

IRAS sends a renewal invitation when your MES is due for review, if you still qualify. You then submit Form R1 through myTax Portal with a fresh certified ASK by the due date in the letter. Your MES stays valid while IRAS decides, and a successful renewal usually lasts another 5 years. IRAS can still revoke the scheme at any time if a condition stops being met.

Who can certify the ASK review for MES?

An individual accredited by the Singapore Chartered Tax Professionals as an Accredited Tax Practitioner (GST) or Accredited Tax Advisor (GST) who has met both the practical and examination requirements, so a provisional accreditation is not enough. They can be your own staff or an external adviser. Either they perform the review themselves, or your team performs it and an external practitioner certifies it by following IRAS’s certification procedures. IRAS may ask to see the working papers.

What is the difference between MES and IGDS?

MES suspends import GST, so it is not paid at import. The Import GST Deferment Scheme defers it instead: approved businesses pay the import GST when their monthly GST return is due, and claim it as input tax in the same return. MES suits businesses that mainly export, while IGDS can suit heavy importers that sell more locally. Both need an ASK review to apply.

What is an ME permit, and who can declare it?

An ME permit is the import permit you take up with Singapore Customs for goods imported under MES. You can declare it yourself through TradeNet, or through up to 20 declaring agents, such as freight forwarders, that you authorise on myTax Portal. The air express companies IRAS names can also use your MES status automatically, and you are accountable for every permit declared under it.
