Singapore Car-Buying Glossary: COE, Taxes, Loans and Rebates
Clear definitions of the terms used in Singapore car quotes, financing, renewal and disposal, with the distinctions that prevent costly mistakes.
Some car-buying terms describe official rules; others are commercial shorthand. Ask a seller to define any ambiguous term in writing, especially when it changes the amount payable or the entitlement you receive.
COE and bidding
COE — Certificate of Entitlement: the entitlement required to register and use a vehicle for its applicable term. A newly registered vehicle normally begins with a ten-year term.
Category A: qualifying non-fully electric cars up to both 1,600cc and 97kW, and fully electric cars up to 110kW.
Category B: cars above the applicable A boundary. OMV is not the A–B classification test.
Category C: goods vehicles and buses.
Category D: motorcycles.
Category E: the open category, usable for eligible vehicles except motorcycles.
Quota: certificates allocated to a category and period. A three-month allocation is different from one exercise’s quota.
Reserve price: a bidder’s maximum authorised COE price.
CCP — Current COE Price: the price during open bidding, determined under the auction rules. Being in the running before closing is not a final award.
QP — Quota Premium: the final category premium paid by successful bidders in an exercise.
Bid deposit: the sum collected when submitting a bid. It is not an extra premium to add again to the final COE cost.
TCOE — Temporary COE: the certificate issued after a successful bid, with a deadline to register a vehicle. Current validity is six months for A/B, three for C/E and one for D.
Registration taxes and emissions
OMV — Open Market Value: the Customs-assessed vehicle import-value basis, not the retail selling price.
Excise duty: duty assessed under the applicable import rules. Do not apply a car rate indiscriminately to every vehicle type.
GST — Goods and Services Tax: a tax with applicable import and retail-sale treatment. Distinguish those stages when reading a cost breakdown.
ARF — Additional Registration Fee: a registration tax calculated using the applicable marginal bands and vehicle rules.
Gross ARF: ARF before applicable emissions adjustments.
Actual ARF paid: the relevant adjusted amount recorded for the vehicle; this is the PARF calculation base.
VES — Vehicular Emissions Scheme: the emissions-based registration adjustment. Use the band and rates applicable to the registration date.
EEAI — EV Early Adoption Incentive: the eligible electric-vehicle ARF incentive under the dated scheme. The announced schedule ends it after 2026.
Financing and the purchase agreement
LTV — Loan-to-Value: the permitted loan proportion under the applicable financing rules. New-car limits use an OMV threshold; a lender must confirm the basis for a used car.
Down payment: the part of the purchase price you fund upfront, separate from other cash reserves and transaction costs.
Flat interest rate: interest calculated on the original principal under the stated method, even as repayments reduce the balance.
Effective interest rate: a borrowing-cost measure reflecting repayment timing under the lender’s stated calculation. It is not interchangeable with a flat-rate headline.
Loan tenure: the repayment period. A regulatory maximum is not a promise that a lender will approve that term for every car.
Guaranteed COE package: a commercial promise whose bidding, price and delivery obligations must be read in the contract.
COE rebate level: a package-contract threshold that may trigger a price adjustment. It is different from LTA’s unused-COE rebate.
Top-up: an additional payment requested or provided for under a purchase agreement. Check when it can be required and what happens if you decline.
PI and AD: parallel importer and authorised dealer. Identify the actual seller and warranty provider; the label alone does not guarantee service quality.
Renewal, ownership and disposal
PQP — Prevailing Quota Premium: the monthly renewal premium based on the preceding three months’ COE premiums. It is not updated only once a quarter.
Five-year renewal: half the applicable ten-year PQP; for ordinary A/B cars and D motorcycles this renewal is final. Commercial-vehicle exceptions require their own checks.
PARF — Preferential Additional Registration Fee rebate: an eligible car rebate determined by actual ARF, age and original COE cohort, including its cap. Renewed COE cars are not PARF eligible.
COE rebate: the eligible unused-entitlement refund at deregistration. It is distinct from PARF.
Paper value: informal shorthand commonly referring to rebate value. Require the quote to list exactly which amounts it includes.
Body or export value: the commercial vehicle value separate from statutory rebates, subject to the actual offer and costs.
Depreciation: value consumed over a holding period, commonly estimated from purchase price less exit value. Do not add it on top of those same purchase and disposal amounts.
Deregistration: removal from the vehicle register. Required disposal steps still need to be completed.
ROPC — Revised Off-Peak Car: a scheme with specified usage restrictions and benefits. Legacy off-peak schemes can differ.
Road tax: the periodic vehicle tax calculated under the applicable powertrain, capacity or power, age and scheme rules.
NCD — No-Claim Discount: an insurance discount subject to the insurer’s policy conditions. It is not a guarantee that every claim leaves the next premium unchanged.
Use the vehicle’s own records
For a decision, take the entitlement, tax, rebate, insurance and financing details from the specific vehicle and written agreements. A glossary explains the terms; it cannot resolve missing contract conditions or determine a particular car’s condition.
