Singapore Car Road Tax Calculator 2026 — LTA Annual Road Tax by Engine Capacity (cc), Age Surcharge for Vehicles Over 10 Years, 6-Monthly Payment & Common Car Model Quick Reference

Singapore road tax for private petrol and diesel cars is calculated by LTA based on engine capacity (cc): S$400 flat for engines ≤600cc; S$400 + (cc − 600) × S$0.25 for 601–1,000cc; S$500 + (cc − 1,000) × S$0.75 for 1,001–1,600cc; S$950 + (cc − 1,600) × S$1.50 for 1,601–3,000cc; S$3,050 + (cc − 3,000) × S$2.00 above 3,000cc. These are annual rates. Road tax is collected every 6 months (semi-annually). Vehicles older than 10 years also pay an age surcharge of 10% per additional year above 10, capped at 50%.

Singapore LTA applies an age surcharge for private cars more than 10 years old: Year 11: +10% of base road tax; Year 12: +20%; Year 13: +30%; Year 14: +40%; Year 15 and beyond: +50% (maximum). The surcharge is based on the base road tax amount, not the total. Example: A 2,000cc car with base road tax of S$1,547 at age 13 pays: S$1,547 + (30% × S$1,547) = S$1,547 + S$464 = S$2,011/year. The age surcharge is LTA’s policy to discourage keeping old vehicles on the road beyond COE maturity, alongside the PARF rebate incentive to deregister within 10 years.

Singapore road tax is paid every 6 months (semi-annually). The amount per payment is exactly half the annual road tax. Example: Annual road tax S$1,550 → 6-monthly payment S$775. Road tax is typically paid through your car insurance renewal (the insurer collects road tax on LTA’s behalf as part of the combined insurance and road tax payment) or directly via LTA’s OneMotoring portal using PayNow, GIRO, or by cash/card at AXS machines. Renewal notices are sent to your registered address before the due date. Failing to renew road tax is a traffic offence in Singapore — cars with lapsed road tax can be issued summons and clamped.

The Toyota Corolla Cross 1.8 (1,798cc engine) annual road tax in Singapore: Formula for 1,601–3,000cc: S$950 + (1,798 − 1,600) × S$1.50 = S$950 + S$297 = S$1,247/year. 6-monthly payment: S$623.50. This is significantly higher than a 1.5L car (S$873/year) due to the 1,600cc threshold — the Corolla Cross crosses into the more expensive road tax band. This also means the Corolla Cross uses Cat B COE (power output >97kW), adding tens of thousands to the purchase price. From a cost perspective, buyers choosing between 1.5L and 1.8L Toyotas should factor in both the higher road tax and Cat B COE premium for the 1.8.

Yes — but EVs use a completely different road tax formula. Instead of engine capacity (cc), Singapore EV road tax is based on maximum power output in kilowatts (kW). The kW-based formula is different from the cc formula and generally results in higher road tax for powerful EVs. For example, a Tesla Model 3 Long Range with ~335kW peak power would pay significantly more road tax than a similarly priced petrol car. However, EVs benefit from EEAI rebates and VES Band A1/A2 rebates that offset total ownership costs. See our dedicated Singapore EV Road Tax Calculator for the full kW-based formula and calculation.

In Singapore, road tax and car insurance are legally linked but technically separate payments. You must have valid car insurance before LTA allows road tax renewal. In practice, most Singapore car owners renew both simultaneously through their insurance agent or insurer. When you pay your 6-monthly car insurance premium, the insurer also collects the 6-monthly road tax amount and remits it to LTA. Some insurers include road tax in a single combined payment; others invoice them separately. If you renew road tax directly via LTA OneMotoring, you’ll need to present proof of valid insurance first. You cannot legally renew road tax without valid insurance, and you cannot legally drive without valid road tax.

For a 2,000cc petrol car, annual Singapore road tax = S$950 + (2,000 − 1,600) × S$1.50 = S$950 + S$600 = S$1,550/year. 6-monthly payment: S$775. If the car is 12 years old, age surcharge applies: S$1,550 + 20% = S$1,550 + S$310 = S$1,860/year. This covers the most common Cat B engine size (2.0L). Popular 2.0L cars in Singapore: BMW 318i, Mercedes C200, Mazda CX-5, Toyota Camry 2.5 (actually 2,487cc → S$1,681/yr). Note: EVs with similar performance to 2.0L cars often have much higher road tax under the kW formula.

DERS (Diesel End-Road Tax) is an additional mileage-based tax for diesel-engined private cars in Singapore, charged at approximately S$0.20 per kilometre driven. It is collected via an in-vehicle unit (IU) — the same cashcard unit used for ERP electronic road pricing. DERS payment method: diesel car owners top up their cashcard IU, and DERS is automatically deducted based on distance travelled. For an average Singapore driver covering 15,000km/year: annual DERS = 15,000 × S$0.20 = S$3,000/year. This is in ADDITION to the standard cc-based road tax. Total road-related annual cost for a 2,000cc diesel car: approximately S$1,550 (road tax) + S$3,000 (DERS) = S$4,550/year — versus S$1,550/year for the equivalent petrol car. This is why diesel private cars are rare in Singapore.

Standard Singapore road tax renewal is for 6 months (semi-annual), and most car owners choose this as it aligns with typical insurance renewal periods. You can also choose to renew for 12 months if you prefer annual renewal. There is no discounted rate for 12-month renewal — you simply pay twice the 6-monthly rate. Some LTA systems allow renewal for other periods (3 months minimum in some cases), but 6 months is the standard. If your car is very close to 10 years old, you may want to calculate whether a 6-month renewal takes you past the 10-year surcharge threshold — if so, the next renewal will be at the higher surcharged rate.

Driving with lapsed road tax in Singapore is a traffic offence under the Road Traffic Act. Penalties: on-the-spot fines for driving without valid road tax; vehicles may be clamped by LTA enforcement officers; accumulated road tax arrears must be paid before the vehicle can be re-registered; enforcement officers also track lapsed road tax via CCTV and automatic plate recognition. LTA sends renewal reminders by mail and SMS in advance of expiry. If you are not using your car for an extended period, you can apply for a “Lay-Up” scheme where road tax is suspended while the car is kept off public roads — useful for extended overseas travel.

If you modify your car’s engine capacity (e.g., engine swap to a larger capacity), the road tax will be recalculated based on the new declared engine capacity. LTA must be notified of significant engine modifications, and the vehicle must pass LTA’s vehicle inspection with the modified specifications. For most standard modifications (remapping, turbo upgrades that don’t change cc), the declared engine capacity remains the same, and road tax is unchanged. Some performance modifications may require updated insurance notification. Illegal modifications — engine swaps without LTA approval — are a traffic offence. Always check with LTA and your insurer before modifying your vehicle.

Yes — company-owned private cars (S-plated vehicles) pay exactly the same LTA road tax as individual-owned private cars, using the identical cc-based formula and age surcharge. The road tax amount is not affected by who owns the car (individual or company). However, for company cars, the road tax cost is a deductible business expense for Singapore corporate income tax purposes. Note: GST input tax on road tax is NOT claimable for private motor cars — even if the company owns and uses the car for business. This is one of IRAS’s blocked input tax items for private cars, regardless of business use.

You can check your Singapore road tax expiry date through: (1) LTA OneMotoring website (www.onemotoring.lta.gov.sg) — under “Enquire Vehicle Road Tax” using your vehicle registration number; (2) Your vehicle’s windscreen — the road tax disc (if applicable) shows the expiry date; (3) Your insurance renewal notice — which typically includes road tax renewal information; (4) LTA’s MyTransport.SG app — available for iOS and Android, which shows vehicle details including road tax status; (5) Contact LTA directly at 1800-CALL LTA. Most Singapore car owners also receive SMS and email reminders from LTA before road tax expiry. If you’re checking for a used car you’re considering purchasing, LTA OneMotoring’s vehicle information service shows road tax status.

Singapore does not offer a direct road tax rebate specifically for “green” petrol/diesel/mild-hybrid cars — all private cars use the same cc-based formula regardless of emissions or fuel efficiency within the petrol/diesel category. However, EVs (zero-emission) use a completely separate kW-based road tax formula, and the overall EV ownership cost is subsidised through: EEAI (EV Early Adoption Incentive) of up to S$7,500 applied against ARF; VES Band A1/A2 rebates of S$10,000–S$25,000 for the cleanest vehicles. For mild hybrids and plug-in hybrids with combustion engines, the standard cc-based road tax applies as if they were petrol cars. Singapore’s road tax policy uses the emissions-linked VES scheme rather than road tax discounts to incentivise greener vehicles.

Large SUVs and luxury cars with engines above 3,000cc pay significantly more road tax: Formula above 3,000cc: S$3,050 + (cc − 3,000) × S$2.00. Examples: 3,500cc: S$3,050 + (500 × S$2.00) = S$4,050/year; 4,000cc: S$3,050 + (1,000 × S$2.00) = S$5,050/year; 4,400cc: S$3,050 + (1,400 × S$2.00) = S$5,850/year. A 4.4L BMW M5 pays S$5,850/year in road tax alone vs S$873/year for a Toyota Vios — 6.7× more. Add the 50% age surcharge at 15 years: S$8,775/year. Singapore’s steeply progressive road tax is a significant ongoing cost for large-engined vehicles, complementing the already expensive COE, ARF, and excise duty on high-OMV cars.

Motorcycle road tax in Singapore is separate from the private car formula and is calculated based on engine capacity in cc but with much lower rates: ≤200cc: S$90/year; 201–400cc: S$90 + (cc−200) × S$0.25; 401–600cc: S$140 + (cc−400) × S$0.50; 601–800cc: S$240 + (cc−600) × S$0.75; above 800cc: S$390 + (cc−800) × S$1.00. For example, a Honda CBR650R (649cc) motorcycle pays approximately S$356/year in Singapore road tax. Motorcycle road tax is far lower than private cars, but motorcycles still require COE (Cat D, approximately S$12,000 in 2026) and ARF. The low annual road tax for motorcycles is one reason motorcycles remain a cost-effective transport option in Singapore despite the COE cost.
