Import GST Deferment Scheme (IGDS)
Singapore's Import GST Deferment Scheme
For businesses in Singapore, managing cash flow is often the difference between scaling up and stalling out. If your company frequently imports goods, the Import GST Deferment Scheme (IGDS) is one of the most powerful financial levers at your disposal.
Here is a comprehensive guide to understanding, qualifying for, and maximizing the IGDS.
What is the Import GST Deferment Scheme (IGDS)?
Under standard IRAS (Inland Revenue Authority of Singapore) rules, GST is payable to Singapore Customs at the point of importation. For businesses with high import volumes, this creates a cash flow lag—you pay the tax upfront and wait months to claim it back as input tax in your GST return.
The IGDS removes this hurdle. It allows approved businesses to defer the payment of import GST until the time their monthly GST return is filed. Essentially, the GST on imports is "accounted for" rather than "paid out," resulting in a zero-sum transaction on your books.
Core Benefits: Why Your Business Needs It
1. Improved Working Capital
By not paying GST upfront at the border, you keep that cash within your business operations for an additional 1 to 3 months.
2. Administrative Efficiency
Streamline your customs clearance process. Since the GST is deferred, the "pay-and-claim" cycle is replaced by a simple accounting entry in your GST return (Boxes 1, 4, and 7).
3. Competitive Advantage
Lowering the cost of doing business allows for more aggressive pricing and faster inventory turnover.
Eligibility Criteria
To qualify for the IGDS, your business must meet stringent compliance and financial requirements:
Requirement | Description |
|---|---|
GST Registration | Must be a GST-registered business in Singapore. |
Compliance Track Record | Excellent tax compliance record with IRAS and Singapore Customs. |
Submission History | Timely filing of GST returns and payment of all taxes due. |
Internal Controls | Robust accounting systems to track and report deferred GST accurately. |
Assurance Schemes | Must undergo a Self-Assessment Tiers (SAT) or Assisted Self-Help Kit (ASK) review by an accredited tax practitioner. |
How to Apply: A Step-by-Step Guide
Conduct an ASK Review: Before applying, you must perform a self-assessment using the Assisted Self-Help Kit (ASK). This ensures your internal GST processes are airtight.
Submit Form GST F22: This is the "Application for Import GST Deferment Scheme" available on the IRAS website.
Appoint a Declaring Agent: Ensure your freight forwarders or declaring agents are informed so they can use the correct "IGDS" permit type during customs clearance.
Pro-Tip: Ensure your "Total Taxable Turnover" and "Total Imports" figures are accurately projected, as IRAS uses these to evaluate the scale of your need for the scheme.
Common Pitfalls to Avoid
Permit Errors: If your agent uses a standard "Payment" permit instead of an "IGDS" permit, GST will be charged immediately, and you cannot retroactively apply the deferment for that shipment.
Late Filing: If you fail to file your GST return on time, IRAS may revoke your IGDS status immediately, causing sudden cash flow shocks at the border.
Record Keeping: You must maintain a clear "Import Deferment Listing" to reconcile your customs permits with your GST returns.
Maximizing Your ROI
If you are already using the Major Exporter Scheme (MES), you might wonder if IGDS is redundant. While MES waives GST entirely for major exporters, IGDS is often easier to maintain for businesses that have a mix of local and international sales.

Checklist for your first ASK Review
Conducting an ASK (Assisted Self-Help Kit) Review is the most critical hurdle in the IGDS application process. It isn't just a formality; it’s a deep dive into your accounts to prove to IRAS that your "tax engine" is running smoothly.
Here is a targeted checklist to prepare your finance and operations teams for a successful IGDS application.
The IGDS "ASK" Pre-Audit Checklist
1. Master Data & System Setup
[ ] Tax Coding: Verify that your ERP or accounting software has a specific tax code for IGDS imports (usually distinct from standard input tax).
[ ] Permit Reconciliation: Ensure you have a process to match Singapore Customs Import Permits with your internal purchase orders.
[ ] Vendor Verification: Confirm that all offshore supplier profiles are updated with correct country codes to prevent GST calculation errors.
2. Transactional Accuracy (The "Three-Way Match")
[ ] The Paper Trail: Can you produce the Commercial Invoice, Packing List, and Bill of Lading/Airway Bill for any random import from the last 6 months?
[ ] Valuation Check: Ensure the "Value of Goods" declared to Customs includes costs, insurance, and freight (CIF), plus any additional commissions or royalties.
[ ] Exchange Rates: Confirm your system uses the MAS (Monetary Authority of Singapore) weekly exchange rate for GST reporting, as required by IRAS.
3. Reporting & Compliance
[ ] Box 1 & 4 Alignment: Practice mapping your deferred GST. The amount deferred must be reported in Box 1 (Standard-rated supplies) and Box 4 (Input tax claimed) of your GST F5 return.
[ ] Box 7 Inclusion: Ensure the total value of the imports (excluding GST) is captured in Box 7 (Total value of taxable purchases).
[ ] Error Correction Policy: Do you have a written internal procedure for what to do if an import is wrongly declared? (e.g., Voluntary Disclosure).
4. External Review Preparation
[ ] Accreditor Selection: Identify an Accredited Tax Advisor (ATA) or Accredited Tax Practitioner (ATP). IRAS requires an external sign-off for the ASK review if you don't have an "ACAP" status.
[ ] Sample Testing: Pre-select 10–20 high-value import transactions and run a "mock audit" to see if the documentation is flawless.
Implementation Strategy: The "Dry Run"
Before you submit the formal Form GST F22, I recommend running a one-month "Shadow Period". Act as if you are on the scheme by tracking your import permits against your GST return boxes, even though you are still paying the GST upfront. This highlights any gaps in your data flow before the tax authorities look at it.
