Scope and import valuation
The twelfth edition dated30 January2026 addresses registered business importers and agents importing for overseas persons. Generally imported goods bear GST regardless of importer registration, except qualifying IPM and import relief. Taxable value includes CIF, duty, commission and incidental charges. If goods were sold before release from Customs control, use the last-supply value plus incidental costs through importation. Convert foreign currency with Customs’ prevailing declaration-time rate. Illustration1: goods10,000+freight/insurance2,000+duty3,600=15,600;9% GST1,404.
Permit, customs control and payment
Activate UEN with Customs and declare the correct permit through TradeNet before bringing dutiable/non-dutiable goods into customs territory. FTZs are outside that statutory territory; FTZ, Zero-GST/licensed/bonded warehouses and excise factories hold goods under Customs control. Obtain release permission and pay GST before removal unless authorised relief/scheme applies. Customs import GIRO is separate from IRAS GIRO; importer or declarant must arrange it. Outsourcing to a freight forwarder does not remove importer responsibility for timely truthful declarations.
Ownership determines domestic versus overseas sales
Ordinarily the owner at import should be importer with the permit in its name. If title passed to the local customer overseas before import, the sale is outside scope and customer imports/pays GST. Do not report that sale as a taxable supply, but include main trading/business revenue in Box13. If seller retains ownership through import, seller imports and later local delivery is standard-rated. From2023 direct LVG sales to non-registered Singapore customers have the stated GST exception, so do not apply the offshore-title rule without considering LVG rules.
Retention-of-title and hire-purchase exception
Where ownership is contractually deferred, possession/control for immediate use can determine place instead. If possession transfers overseas, customer imports even if title passes after arrival. Examples include the customer collecting from an overseas warehouse and arranging export/import clearance, or delivery alongside/on the customer’s vessel overseas with risk/cost passed then. Determine agreement and actual conduct; a retained-title clause alone does not force seller to be importer.
Input conditions, documents and the permit-date period
Goods must be supplied to you or imported in an eligible33(2)/33A capacity, for business and directly taxable or out-of-scope supplies that would be taxable locally; apply normal attribution rules and exclude blocked26/27 costs. Keep your-name import permit, supplier invoices and transport evidence. Section6.2’s documentation has force of law. Report permit-date period value in Box5 and eligible paid GST in Box7. Temporary own-goods export/reimport may qualify for input or advance relief, subject to their conditions.
Courier exceptions and TNT’s historical name
For specified express imports the source accepts courier tax invoices instead of import permits: Federal Express, UPS and DHL Express, with TNT named historically but amalgamated into Federal Express from1 October2021. Other logistics imports still require the named-importer permit. Under MES the specified air-express inward summaries or subsidiary import certificates support scheme reporting. This is a specific evidence concession, not permission to claim all logistics invoices as import GST.
Over-declaration: correct value, actual tax
Illustration2 permit overstates goods10,000/GST900 though correct goods1,000: Box5 reports1,000 and eligible actual tax Box7 reports900. Do not copy the overstated value into purchases merely to match tax. Under suspension schemes over-declarations use correct value in Boxes5/9 and retain invoices/reconciliation; no paid input exists to claim.
Under-declaration and short-payment permits
Take a short-payment permit referencing the original and pay shortfall. Claim eligible extra GST in that permit’s period. Illustration3 originally1,000/90, true3,000/270, extra2,000/180: same-period short permit gives Box5 3,000/Box7 270; later period gives original1,000/90 then2,000/180. Suspension-scheme under-declarations instead report correct value in5/9 without an extra shortfall permit, supported by reconciliation.
Wrong importer, wrong permit and duplicate permits
Wrong importer name prevents the rightful party’s claim. Both parties notify Customs with evidence, rightful importer takes replacement permit and claims subject to conditions, and wrongly named importer seeks Customs refund. If a scheme participant mistakenly pays instead of suspending/deferring, claim eligible actual tax in permit-period5/7 with payment proof. For duplicate payment permits on one shipment, additional paid tax may be claimed in7 in their permit periods with permits retained. These corrections do not authorise two parties to claim the same tax.
Section33(2): import and then supply
An agent importing to supply locally/export for a non-registered overseas principal or OVR pay-only principal is deemed principal for GST. Claim eligible imports5/7 or suspension5/9, with IGDS extra section when used. Local supplies need tax invoice and1/6; qualifying documented exports2. Goods may change form if traced through import/supply. Separate own records from each principal’s imports/sales. Agency authority is not a general right to use another entity’s GST registration.
33(2) deregistration and repayment
If principal stock remains on deregistration, later supply is no longer taxable and agent qualification ends. Repay prior claimed import via F7 reducing original5/7; suspended tax through output6 in final return; last-period IGDS deferred tax remains payable without input recovery in its deferred-tax/goods fields. The source states post2020 field numbers17/19 in8.8 but older15/17 remain in8.12; follow the field names and post2020 renumbering, not the obsolete pair.
Change of agent: all seven conditions
A no-payment transfer with principal retaining title is not a supply. To avoid repayment both agents keep termination/appointment proof; title stays overseas/no transfer payment; new agent is registered on transfer date; nature/form is unchanged unless prior approval; both keep inventory date/description/quantity/value/delivery/stock lists; old agent accounts tax on discrepancies; new undertakes all supply/report/record duties and repays if it fails. Section8.10 has legal force. Submit original joint self-review before transfer and retain copies; ordinary qualifying transfer may proceed after submission without further approval.
Non-qualifying transfer and changed goods
If a condition fails, reverse prior claimed tax via F7, pay suspended output6 in transfer period, or account deferred IGDS without input in the applicable fields. Same-period IGDS and transfers in later periods differ as the source’s note explains. Changed form requires written approval before transfer, describing commercial reasons and traceability from import to transfer to eventual supply. Approval to process goods as the original agent does not automatically approve an agent change for those processed goods.
Consignment agent buying the goods itself
Dual role as33(2) agent then buyer can arise on consignment. IRAS waives self-issued tax invoice on principal-to-agent sale, but not GST accounting: report that transaction as the agent’s standard-rated supply/output and taxable purchase/input concurrently. Continue tax invoices for later local sales and all other agent duties. No-self-invoice waiver is not a waiver of the intermediate deemed supply.
Section33A: import then export without a supply
Eligible principal is overseas non-registered or OVR pay-only. Import tax must have been claimable had principal itself registered/imported; agent must not obtain reimbursement or add tax to service charges, import for a qualifying purpose, retain control/oversight and track processed goods. Export or install/fit on ship/aircraft within three years or before agent deregistration, whichever earlier. Qualified MES/IGDS/other schemes may suspend/defer. Receiving goods through an outsourced processor still requires them to return to the agent.
All six33A purposes and return reporting
Purposes are tools/machinery processing other goods supplied to principal; ship/aircraft components; storage/transit; exhibition/convention; processing/treatment; and leased-owner goods used in Singapore. Carry out activity or deliver to a third party and receive back. Report import5/7 or suspension5/9 and IGDS section if relevant; later export value goes in2 with documents despite no onward sale. Keep separate principal imports from own. This statutory import/export reporting is not omitted just because ownership never changed.
33A failures and exceptions
Failure to carry out purpose, retrieve outsourced goods or export/install ends eligibility and requires repayment in output6, finalF8 if deregistered. Exceptions listed are obsolete/spoiled disposal or owner-instructed disposal; loss/destruction by fire/flood/theft; owner-instructed sales with output accounted; exhibition sales with output accounted. The last two become33(2) import-and-supply situations. Do not extend these specific exceptions to undocumented shortages.
Section33(1): principal’s registration and MES
33(1) substitutes for a registered overseas principal’s GST duties. Use principal’s GST number for supplies/returns but agent’s UEN for import, permit “agent on behalf of principal”. Report imports/input in principal’s return. Agent’s own MES cannot import for that registered principal; principal needs its own approved MES, which agent uses only for principal’s goods, never its own. An OVR pay-only principal may instead appoint33(2), which performs those import/report duties rather than33(1).
Controlled goods imported by a different authorised handler
If principal/33(1) agent lack required controlled-goods licence/approval, another handler must hold necessary agency authorisation and must not claim import GST.33(1) responsibility remains. Principal keeps contracts, supplier invoice, permit, its import-tax payment, transport/packing documents, handler appointment, proof of missing licence and handler’s no-input-claim declaration. This evidence supports principal’s claim rather than granting unlicensed import permission.
Section33B value-added reimports
From2015 eligible agents can recover GST on local/registered-overseas customer goods they sent overseas for testing, repair, assembly or manufacture and reimport. MES, IGDS, ACMT contract manufacturers and ARCS approved refiners may use authorised suspension/deferment. Section33B/regulation42B requirements are detailed in the separate reimport guide; this overview does not exempt all third-party reimports automatically.
FTZ overseas versus local goods
Overseas goods stored/transhipped/sold within FTZ are generally no import GST/outside-scope; use or consumption there triggers Customs GST. Removal to local consumption pays GST, while permitted movement to another FTZ/approved warehouse or authorised scheme retains relief. Local goods sold within FTZ remain standard-rated except stated export, qualifying-ship use/install, qualifying-aircraft/nonqualifying-ship stores/fuel and onboard retail cases. Local goods re-entering territory pay import unless relief. Report release5/7 and subsequent sale1/6.
Warehouses and import relief
ZG warehouses store non-dutiable imports; licensed warehouses suspend duties/GST on liquor/tobacco/vehicles/petroleum. Initial warehouse imports report5 despite suspended tax; local release reports value5 again and eligible tax7, then sale1/6. Direct warehouse export reports2. Relief examples: air/post total≤400 excluding liquor/tobacco, disregarding IPM value; above400 the entire taxable sum is taxed; temporary imports for approved purposes/reexport generally within three months; temporary own export/reimport. Apply Customs relief before arrival/export. Without advance relief pay GST then claim only if eligible; relieved import still reports5.
MES and IGDS differ
MES suspends non-dutiable imports to ease exporters’ cash flow: own business,33(2)/33A principal goods and eligible33B reimports; accurate controls and returns remain. IGDS defers GST to return submission for both dutiable/non-dutiable imports, warehouse releases and qualifying excise-factory releases with prior supply; customs/excise duties still upfront. Pay deferred tax in payable period and separately claim eligible input. Neither approval automatically gives full input entitlement.
Other industry schemes and contact routes
A3PL covers approved logistics’ own/principal imports and ZG removals, plus specified transfers to MES/A3PL customers without GST. ACMT covers semiconductor/printing/API contract manufacture, qualifying value-added services disregarded on export/ACMT transfer/final-client delivery and authorised imports/reimports. AISS covers aerospace imports and qualifying aircraft-part removal from ALPS/FTZ regardless of origin. ARCS refiners cover own/agent/consigned refining and eligible reimports; consolidators cover own/consigned goods for refining. Each scheme needs its detailed approval conditions. Registered enquiries use myTax Mail; others IRAS GST enquiry route, Customs for permit/relief administration.
