Singapore Road Tax 2026: Rates, Calculator and Renewal Guide

Last updated: October 2026 | SeaMoneyTips

Singapore road tax is one of the fixed running costs of owning a vehicle, and it is the part most owners get wrong when they budget. The amount is not a flat annual charge. It is calculated from your engine capacity, then adjusted for the age of the car, and for electric vehicles it is calculated from motor power rating instead. On top of that sits a surcharge for cars older than 10 years, and a separate late renewal penalty if you let the tax lapse.

This guide walks through the LTA formula, gives you worked examples in dollars for common engine sizes, shows how much an electric car pays under the Additional Flat Component, lists every renewal channel, and explains the renewal prerequisites you must clear before LTA will let you pay.

What Is Singapore Road Tax and How Is It Calculated?

Road tax is part of the vehicle ownership tax structure in Singapore, alongside the Registration Fee, the Additional Registration Fee and the Certificate of Entitlement (COE). Every registered vehicle must hold valid road tax, and keeping a vehicle with expired road tax is an offence that can attract a fine of up to S$2,000. Understanding Singapore road tax before you buy avoids both surprise bills and late renewal penalties.

The tax is not discretionary and not negotiable. It is renewed for 6 months or 12 months at a time, and the LTA calculates the base amount using a formula based on engine capacity in cc. Every petrol, CNG and diesel car uses the same schedule, and every figure in that schedule is multiplied by 0.782. That single rule is what makes Singapore road tax predictable for most owners, provided you know where your engine capacity sits.

The LTA road tax formula by engine capacity

Note how the formula works in practice. A 1,600 cc engine sits at the top of its band, so the next cc costs only S$0.375 more, while a 1,601 cc engine jumps into a steeper band. This is why two cars with similar real-world performance can carry road tax bills that differ by hundreds of dollars a year.

Before you budget for road tax, it is worth understanding how it sits alongside your other vehicle costs. If you are still weighing up financing, our Singapore car loan guide for 2026 covers the loan-to-value limits and tenure rules that decide how much cash you need upfront. Road tax is an annual commitment on top of that, so it belongs in the same budget conversation.

Singapore Road Tax Rates 2026: Worked Examples

The table below applies the LTA formula to common engine capacities and multiplies by two for a 12-month renewal. The last column adds the 10% age surcharge that applies once a vehicle passes 10 years old.

The jump between 1,600 cc and 2,000 cc is the single biggest surprise most owners hit. The 12-month bill almost doubles across that range, from about S$743 to about S$1,212. If you are shopping between engine sizes, this is the line item that should influence the decision, and it is also a legitimate reason to look at a smaller or more efficient car. Checking Singapore road tax for two shortlisted vehicles before you commit saves more than any negotiation tactic.

Road tax surcharge for vehicles over 10 years old

Once your vehicle is more than 10 years old, an annual surcharge is added on top of the base road tax. The percentage rises with each additional year of age.

For a 2,000 cc car that is now 12 years old, the annual bill rises from S$1,212.10 to about S$1,575.73. It is a permanent addition to the running cost, and it is one reason that older cars in Singapore can be cheaper to buy but more expensive to keep.

Electric Vehicle Road Tax and the Additional Flat Component

Electric cars do not pay road tax based on engine capacity, because they have no engine. Instead, the LTA uses the maximum power rating of the motor in kilowatts, which the LTA calls the PR. For a car with more than one motor, the PR is the combined total.

The flat S$350 per 6 months is the Additional Flat Component, and it exists because electric vehicles do not pay fuel excise duty. The LTA's own comparison puts fuel excise duty for a typical internal combustion car user at about S$1,000 a year, so the AFC replaces that usage tax inside the road tax bill.

Worked example: an electric car with a 150 kW power rating pays 6-monthly road tax of S$547.40 plus the S$350 flat component, which is S$897.40 for the half year, or S$1,794.80 for a 12-month renewal. That sits between a mid-size combustion car and a large one.

For petrol-electric cars, the LTA calculates the road tax twice, once using engine capacity and once using the maximum electric power rating, and you pay whichever amount is higher. This is a detail that catches out people who assume hybrids get a discount, and they do not. Diesel cars also attract a separate Special Tax on top of road tax, with the amount depending on the Euro emission standard of the vehicle.

How to Renew Singapore Road Tax

There are four ways to renew road tax in Singapore, and all of them require you to clear the renewal prerequisites first. The critical timing rule is that you must meet every prerequisite at least 1 working day before you pay. Try to renew on the same day and the payment will not go through. Getting Singapore road tax renewal right takes about ten minutes of preparation.

Renewal prerequisites you must clear

• Vehicle insurance. The vehicle must be insured for the full period you are paying road tax, and the policy must cover third-party liability for death and bodily injury. Driving without insurance coverage is a serious offence in its own right.
• Vehicle inspection. If a periodic inspection is due, you must pass it. You normally receive an inspection notice about 3 months before road tax expires. If you have lost the notice, you can still get the vehicle inspected at an LTA-authorised inspection centre without it.
• Outstanding fines and warrants. Unpaid fines or warrants from LTA, HDB, URA and the Traffic Police can block your renewal.
• Special rules for some vehicles. Weekend Cars, Off-Peak Cars and Revised Off-Peak Cars can only be renewed on a 12-monthly basis and need their number plate seals inspected. Heavy vehicles, defined as more than 5,000 kg maximum laden weight, a bus with more than 15 passenger seats, a trailer or mobile crane, or a recovery vehicle with unladen weight above 2,500 kg, must hold a valid Vehicle Parking Certificate.

The insurance requirement is where most renewals fail. If your motor policy is due for renewal in the same month, renewing the road tax first leaves you blocked, because the insurer needs the new road tax validity date to issue the policy. This is the usual chicken-and-egg problem, and it is easier to solve by renewing insurance first. Our Singapore motor insurance guide 2026 explains the policy types and how to read a certificate of insurance.

1. Renewing online at OneMotoring

Online renewal is available all day except between midnight and 1.00am. You need sufficient funds in your bank account with a payment limit that covers the amount, plus either a valid Visa or Mastercard, or an Internet Banking account with DBS/POSB, OCBC/Plus!, Standard Chartered or UOB for eNETS Debit. This is the fastest route for most owners and it takes a few minutes.

2. Paying at an AXS station

AXS stations are also open all day except between midnight and 1.00am. At physical stations you can pay by ATM card from DBS, POSB, HSBC, Maybank, OCBC, Standard Chartered or UOB, or by DBS and POSB credit card. At AXS m-Station and e-Station, you can pay by eNETS Debit, Mastercard Debit, DBS Paylah! or MasterPass.

3. Letting GIRO handle it

GIRO is the set-and-forget option. You can choose 6-monthly (the default) or annual deductions, and the money leaves your account automatically. For new GIRO sign-ups made from 29 December 2024, every vehicle registered in your name, existing and future, is added to the arrangement automatically.

The mechanics matter. LTA sends you a payment schedule about 1 month before road tax expires, and it states both the deadline for meeting prerequisites and the deduction date. The deduction happens 5 working days before expiry, and if that date falls on a weekend or public holiday, it moves one working day earlier. You need enough funds and an adequate payment limit in your account, or the deduction fails and you must renew by other means. Applications through eGIRO get instant approval for individual account holders at DBS/POSB, OCBC, UOB, Maybank, Bank of China, Citibank, ICBC, Standard Chartered and HSBC.

4. Visiting a road tax collection centre

Physical collection centres remain available. You must bring the original prerequisite documents, such as your motor insurance certificate and vehicle inspection certificate. Since 1 February 2025, cash, cheque and cashier's order are no longer accepted for road tax renewals at inspection centres, so check the accepted payment modes before you go. You can find the current list of authorised centres on the LTA road tax collection centres page.

Late Renewal Fees and Penalties

Renewing on time costs nothing extra. Renewing late costs a flat penalty on top of the road tax itself, and the penalty scales with how late you are and how large your engine is. The table below shows the late renewal fees for cars. Keeping Singapore road tax current is one of the cheapest savings available to any vehicle owner.

The LTA example is worth remembering: if the owner of a car with an engine under 1,000 cc renews at 3.5 months past expiry, they pay a late fee of S$230 on top of the road tax. For a motorcycle, the late fee structure is similar but the longest tier is measured from more than 6 months, with S$130 for engines under 300 cc and S$230 for 300 cc and above. Nothing about these penalties is negotiable, so plan Singapore road tax renewal around your expiry date rather than around your cash flow.

Late renewal fees are only the financial side. It is also an offence to keep or use a vehicle whose road tax has expired, and you can be fined up to S$2,000 for that. If you have been charged more than you think is fair, the LTA publishes a calculator that checks the late renewal fee for your situation.

Road Tax When You Buy, Sell or Deregister a Vehicle

Road tax follows the vehicle, not the owner, and this matters if you are in the middle of a transaction.

• Buying. Ask the seller whether road tax is already paid. When you buy a new vehicle, the road tax may be bundled into the total price, so check with your motor dealer. For a used vehicle, confirm the road tax is valid before you drive it away.
• Selling. Any road tax already paid transfers to the new owner. If you sell before expiry, you can factor the unused road tax into your asking price. If the road tax expires before you can complete the sale, you must renew it first.
• Deregistering. Any unused portion of road tax paid is refunded automatically to the last registered owner.

Since 15 February 2017, you no longer display a road tax disc on your windscreen. If you remove an old disc, that is fine. But if you are driving into Malaysia, you must carry a valid copy of your certificate of insurance plus a PDF or printout of your latest road tax validity in the vehicle.

How to Check and Keep Your Road Tax Bill Under Control

There are two digital services on the LTA platform that let you check what you owe before you pay. You can check road tax by Vehicle Registration Number, or by engine capacity and vehicle age if you have not settled on a specific car yet. That second option is the one to use when comparing vehicles, because it lets you price the road tax line of two cars before you commit to either. It is the fastest way to check Singapore road tax for a car you are still considering.

Three practical habits keep the bill predictable. First, renew on a 12-month basis where your cash flow allows it, because the annual figure works out the same but you avoid a second renewal cycle and the risk of a missed deadline. Second, set the annual check at the same time as your insurance renewal so the two prerequisites clear together instead of blocking each other. Third, keep money set aside in a low-cost account for the annual bills. Our guide to the best fixed deposits in Singapore for 2026 covers parking idle cash while still keeping it accessible for the year.

Vehicle choice has the largest effect. A smaller engine capacity keeps you in a lower road tax band, and choosing a car that sits just below a band ceiling can save more per year than any discount you negotiate elsewhere. For the wider context on running costs and household money management, our Singapore budget 2026 guide and Singapore Assurance Package 2026 explainer cover the cash-flow side of owning a vehicle in Singapore.

Common Questions About Singapore Road Tax

Key Takeaways

• Road tax is calculated from engine capacity and multiplied by 0.782, then adjusted for vehicle age and vehicle type.
• A 1,600 cc car pays about S$743 a year, while a 2,000 cc car pays about S$1,212. The band jumps between these two sizes are the most expensive decision you make.
• Cars more than 10 years old pay an annual surcharge that rises from 10% to 50% as the vehicle ages.
• Electric cars are taxed on motor power rating and add a flat S$350 per 6 months as the Additional Flat Component.
• Clear insurance, inspection and outstanding fines at least 1 working day before renewing, or the payment will be rejected.
• Late renewal fees run from S$10 to S$270, and driving a vehicle with expired road tax can also mean a fine of up to S$2,000.

Conclusion

Singapore road tax is predictable once you understand the formula. Get your engine capacity, apply the band, multiply by 0.782, add the age surcharge if it applies, and you have your annual number. Then plan the renewal as a two-step process: insurance first, inspection second, road tax third, all at least 1 working day ahead of expiry. Set up GIRO so the money leaves automatically, and keep the annual amount aside in a low-cost account so a lapse never happens. If you are still building your overall household budget around a vehicle, start with our Singapore COE guide 2026 to understand the upfront cost that sits before road tax ever begins.
