If you own, buy or sell a vehicle in Singapore, sooner or later you will end up on OneMotoring. It is the Land Transport Authority’s (LTA) one-stop motoring portal, and it handles most of the paperwork that used to mean a trip to a counter: renewing road tax, transferring ownership, checking a car’s records, following Certificate of Entitlement (COE) bidding and deregistering a vehicle.
This guide is for car owners. Commuters looking for bus arrival times and train information want a different tool, LTA’s journey planning app, not OneMotoring. Here we walk through the main e-services, what you need before you start, and the mistakes that commonly trip people up. Fees, steps and rules can change, so always rely on what OneMotoring itself shows when you log in.
What OneMotoring Is and How to Log In
OneMotoring is a website run by LTA that combines two things:
- Information pages on buying, owning and disposing of vehicles, COE, road tax, Electronic Road Pricing (ERP), inspections and more.
- Digital services (e-services) where you actually carry out transactions for your own vehicle.
To use the e-services as an individual, you log in with Singpass, Singapore’s national digital identity. Businesses that own company vehicles generally transact using Corppass, the corporate equivalent, with access granted by the company’s administrator.
A few things that help before you start:
- Have the Singpass app set up on your phone.
- Know your vehicle registration number and, for some services, details from your vehicle records.
- Have a payment method ready. OneMotoring accepts common electronic payment methods for fees; the options are shown at checkout.
- Use an up to date browser on a computer for longer transactions, though many services work on mobile.
Renewing Road Tax on OneMotoring
Road tax is the most common reason owners visit. You can typically renew it online for six or twelve months, depending on what is offered for your vehicle.
For renewal to go through, certain conditions usually need to be met. The common ones are:
- Valid motor insurance covering the new road tax period. Insurers update LTA’s records electronically, so if you have just renewed your policy, it can take a short while to appear.
- A valid inspection pass if your car is due for periodic inspection. Cars above a certain age need to pass inspection at an authorised centre before road tax can be renewed.
- No outstanding issues on the vehicle that block renewal. If something is blocking it, the portal generally tells you what.
Tips:
- You will get a reminder before road tax expires, but do not rely on it. Note the date yourself.
- Late renewal can attract a late fee, and driving with expired road tax is an offence.
- Diesel cars pay a special tax on top of road tax, which appears in the amount shown.
- After renewing, you do not need to display a paper disc. Records are electronic.
Transferring Vehicle Ownership
When a car is sold directly between individuals, the transfer happens on OneMotoring. In general:
- The seller starts the transfer by logging in and entering the buyer’s details.
- The buyer logs in and accepts within the time window set by LTA, and pays the transfer fee.
- Insurance must be in place for the new owner. The buyer should arrange this before or as part of the process, as the car cannot be driven without valid cover.
- The transfer completes once all steps are done, and both parties can check the updated record.
Important points:
- Settle outstanding fines and payments first. Some outstanding matters can hold up a transfer.
- Agree on who pays what (transfer fee, remaining road tax, any loan settlement) in writing before starting.
- If the car has a loan, the financing company may need to be involved, and the loan usually must be settled before ownership can change.
- Dealers handle this for you if you sell through one, but it is still worth checking the record afterwards.
If you are selling or buying privately, our guides on selling your car without a dealer and buying from a direct owner cover the negotiation and paperwork around the transfer.
Following and Joining COE Bidding
COE bidding happens through regular open bidding exercises run by LTA. OneMotoring is where you find:
- The bidding schedule and the categories (cars by engine capacity and power, goods vehicles, motorcycles and the open category).
- Live bidding information during an exercise, including current prices and the number of bids.
- Results and historical Quota Premiums.
Bids themselves are usually submitted through participating banks’ channels (such as ATMs or internet banking) or through a motor dealer acting for you, rather than inside OneMotoring. Most individual buyers let their dealer bid as part of the car package. If you bid yourself, read LTA’s bidding rules carefully, including the deposit and what happens if your bid is unsuccessful. When your COE nears expiry, OneMotoring is also where you check the Prevailing Quota Premium (PQP) used for renewing it.
Other Useful E-Services
Beyond the big three, OneMotoring is handy for:
- Checking vehicle details, such as the COE expiry date, road tax expiry and rebate values.
- Deregistering a vehicle for scrapping or export, and checking the rebates (such as the PARF rebate and unused COE value) you may receive.
- Checking and paying LTA fines and notices.
- Updating particulars, such as your mailing address, if required.
- Information on ERP and in-vehicle units, including any changes to the system.
- Handling a vehicle after the owner dies, where the next of kin or executor needs to manage transfer or deregistration. Our guide on handling a car after the owner passes away explains the wider process.
Which Service to Use for Common Tasks
| Task | Where on OneMotoring | What to have ready |
|---|---|---|
| Renew road tax | Digital services for vehicle owners | Singpass, valid insurance, inspection pass if due |
| Sell a car privately | Transfer of vehicle ownership | Buyer’s details, settled fines and loan |
| Buy a car privately | Accept transfer of ownership | Singpass, insurance, payment for the fee |
| Check COE prices | COE bidding results and live bidding pages | Nothing, these are public pages |
| Scrap or export a car | Deregistration services | Singpass, vehicle details, scrapyard or export arrangements |
| Check rebates | Vehicle enquiry services | Vehicle registration number |
Common Mistakes to Avoid
- Using lookalike websites. Always type the address yourself or go through LTA’s official site. Be wary of links in SMS or email asking you to pay road tax or fines. Government sites end in .gov.sg.
- Letting the transfer window lapse. If the buyer does not accept in time, the seller may need to start again.
- Forgetting inspection dates. Older cars need inspection before road tax renewal, and inspection slots can fill up.
- Assuming fees from old articles. Fees and rules change. Trust what the portal shows at checkout.
- Sharing Singpass details. Never let a seller, buyer or agent log in on your behalf. Use the proper authorisation routes.
With a little preparation, most OneMotoring tasks take minutes. Bookmark the official site, keep your insurance and inspection dates in your calendar, and the portal does the rest.
Frequently Asked Questions
Can foreigners use OneMotoring without a Singpass? Some services need Singpass, but not every foreigner has one. Check OneMotoring for the login options for your pass type, and for what can be done at an LTA service point or through an authorised agent. Never share your login details.
Can someone else renew my road tax or transfer my car for me? Use the official authorisation routes shown on OneMotoring rather than giving anyone your Singpass login. Dealers and agents can act on your behalf through proper channels. If a family member is helping, check which services allow it.
Why did my road tax renewal fail even though I have valid insurance? The usual causes are a delay in the insurer’s update to LTA’s records, an inspection that is due, or an outstanding matter on the vehicle. Wait a short while after renewing the policy, then try again. The portal normally tells you what is blocking it.
Does OneMotoring cover motorcycles and company vehicles too? Yes, it handles many services for motorcycles, and businesses use Corppass for company vehicles. Some rules, such as COE categories and inspection schedules, differ by vehicle type. Check the vehicle type before starting any transaction.
Is there a OneMotoring mobile app, or only the website? Many services work on a mobile browser, but an app option may exist, so check LTA’s official channels for what is currently offered. Whichever you use, go directly to the official government address instead of links in messages.
