How to Renew COE in Singapore: PQP, 5 vs 10 Years, and PARF Explained

When your car hits its 10th birthday in Singapore, you face one of the most consequential financial decisions in car ownership: renew the COE and keep driving, or deregister and walk away with whatever the government refunds you. Neither answer is automatically right. The correct choice depends on the Prevailing Quota Premium at the time of your renewal, your car's remaining PARF value, the car's mechanical condition, and whether you factor in Budget 2026's dramatic changes to how PARF rebates work.

This guide covers exactly how COE renewal works, what it costs in 2026, and how to model the decision before you commit tens of thousands of dollars.

First: How to Check Your COE Expiry

You can check your COE expiry date on the LTA's OneMotoring portal. Log in, navigate to "Enquire Vehicle Information," and enter your vehicle registration number. The expiry date is displayed alongside your current road tax status.

Your insurer also tracks this — they'll flag up the renewal window when it approaches. The practical renewal window opens at the 12-month mark before expiry and closes on the expiry date itself. If you miss it, the car must be deregistered.

What Is PQP and How Is It Calculated?

The Prevailing Quota Premium (PQP) is the price you pay to renew your COE. It's not the same as the current bidding price — it's a 3-month moving average of the Quota Premium (QP) from recent bidding exercises.

As of February/March 2026, the PQP rates are: - Category A PQP: approximately S$107,571 (February) / S$106,541 (March) - Category B PQP: approximately S$120,772 (February) / S$115,938 (March)

The 3-month average smooths out short-term volatility, which is both good and bad. If COE prices drop sharply in the coming months, your PQP will lag. If they spike before your renewal date, the PQP shields you from the worst of it. Because PQP is calculated continuously, the specific month you renew affects your cost.

5-Year vs 10-Year Renewal: The Core Decision

When you renew, you choose between a 5-year and a 10-year extension. The cost difference is significant, but the implications go beyond the price:

The critical point that most guides miss: When you renew for either 5 or 10 years, you immediately forfeit your PARF rebate. The PARF value disappears the moment renewal is processed.

So if your car has a PARF rebate of S$10,000, the true cost of a 5-year renewal is not S$53,000 — it's S$53,000 plus the S$10,000 you gave up. That makes the real cost S$63,000 over 5 years, or S$12,600 per year for the COE component alone, before running costs, insurance, road tax, and maintenance.

What Is PARF and Why Does It Matter?

PARF stands for Preferential Additional Registration Fee. It's a rebate that the government refunds you when you deregister a car within its first 10 years of life. The rebate is calculated as a percentage of the ARF (Additional Registration Fee) you paid when the car was first registered.

Under the pre-2026 system, the PARF rebate at age 9–10 was 50% of ARF, with a maximum cap of S$60,000. This created a meaningful "exit value" — a mass-market car with S$20,000 in ARF paid might return S$10,000 at deregistration.

Budget 2026 changed this fundamentally. For cars registered from 13 February 2026 onwards: - The PARF rebate at 9–10 years drops from 50% to 5% of ARF - The maximum cap drops from S$60,000 to S$30,000

For a luxury car with S$80,000 in ARF, the scrap-time refund collapsed from S$40,000 to S$4,000. For a mass-market car, the change is proportionally similar. New cars registered after February 2026 effectively have near-zero backend value — you're amortising the full purchase price over 10 years with almost nothing coming back.

Cars registered before February 2026 still carry the old, higher PARF rebate schedule. This makes them more valuable as used cars — they represent a higher guaranteed backend cash-back upon eventual deregistration.

The Renewal vs New Car Comparison

Given Budget 2026's PARF cuts, the case for renewal has actually strengthened for many owners:

Scenario: 2016 Honda Civic on 10-year COE - 5-year renewal cost: ~S$53,000 (50% Cat A PQP) - Annual cost: S$10,600/year for the COE component - End of 5 years: car must be scrapped, minimal return - Maintenance risk: variable, depending on car's condition

Scenario: New 2026 Honda Civic equivalent - On-the-road price: ~S$160,000 - Downpayment needed: S$64,000 (40% of OMV-adjusted loan limit) - Annual depreciation: ~S$15,500/year (car price minus ~S$2k new PARF value, over 10 years) - Loan repayments on top: ~S$850–950/month on a 7-year loan

The renewal wins on cash flow. But the new car wins on reliability and the absence of accelerating maintenance costs for an ageing vehicle. Neither choice is clearly superior — the correct answer depends on the specific car's mechanical history and your personal cash flow situation.

Road Tax Surcharge for Older Vehicles

There's an additional cost to keep in mind for cars beyond their original 10-year lifespan: the road tax surcharge. Vehicles older than 10 years pay a surcharge that increases by 10% per year, capped at 50% above the base rate. For a car with S$742 base road tax, the maximum surcharge adds S$371 per year by year 15. This is a running cost that new car buyers don't face.

How to Process COE Renewal via OneMotoring

The renewal itself is administratively straightforward:

1. Log in to OneMotoring (onemotoring.lta.gov.sg) with your Singpass
2. Select "Vehicle Ownership" → "Renew COE"
3. Enter your vehicle registration number
4. Select 5-year or 10-year renewal
5. Payment is made in full at the time of renewal — PQP is non-negotiable and cannot be partially paid via loan (for 5-year renewals especially, loan financing is difficult to arrange)
6. Renewal is processed immediately upon payment confirmation

Some banks offer COE renewal loans, though these are less common than standard car purchase loans. The Singapore COE Navigator includes a COE renewal loan calculator that converts the quoted flat rate into effective interest rate — the gap between the two can be significant over a multi-year term.

When Does Renewal Make Financial Sense?

The mathematics depends on three variables: PQP level, your car's remaining PARF value, and the car's expected maintenance costs. The general framework:

Lean toward renewal when: - The car is mechanically sound with a reliable service history - Your PARF rebate has already reduced significantly (approaching 10-year mark), so forfeiture cost is low - Monthly cash flow is constrained and you cannot absorb a S$64,000+ downpayment - The car is a known-reliable model (Toyota, Honda hybrids) with predictable maintenance

Lean toward deregistering and buying new (or used pre-2026) when: - The car has recurring faults or known high-cost failures ahead (DSG gearboxes, ageing hybrid batteries) - Your PARF rebate is still substantial (early in the car's life when renewal is less common) - You can structure the new purchase cash-efficiently - The mechanical inspection reveals problems that will exceed renewal cost savings

The Singapore COE Navigator includes a 5-vs-10-year decision matrix with worked calculations for both scenarios — inputs include your specific PQP month, current PARF value, estimated running costs, and replacement cost. It calculates year-by-year cost comparison so you can see the break-even point clearly.
