Most people who need to pay an ERP fine in Singapore are paying more than they have to. Since 1 October 2024, a missed ERP charge no longer becomes a fine on the spot. LTA texts you, and you get a five-day grace window from the date of that SMS to settle the toll with no penalty added. Pay inside the window and you owe only the original ERP amount, often a dollar or two. Miss the window and a physical violation letter follows, stacking a $10 administrative charge on top. Ignore that and it climbs to a $70 fine, then a court summons. The whole game is about acting on the SMS before it becomes paper.
An ERP fine is not a separate offence ticket. It starts as a missed road-pricing charge. When you drive under a gantry and the system cannot deduct the toll, because your stored-value card is low, your card is unread, or your unit has a fault, the charge goes unpaid. LTA records the pass and bills you afterwards.
There are two distinct numbers to keep straight. The first is the ERP charge you owe, which is whatever the gantry cost at that moment, frequently between $0.50 and $4 in 2026 depending on the road and time. The second is the penalty layered on if you are slow to pay: a $10 administrative charge, escalating to a $70 fine. Knowing how to GST and admin fees attach to a small toll is the difference between paying $2 and paying $70.
If you want to stop landing here in the first place, the cleanest fix is keeping enough stored value loaded and your contact details current. Our guide to ERP rates and avoiding ERP fines breaks down what each gantry charges so a low balance never surprises you.
This is the single most valuable thing to know. From 1 October 2024, LTA sends an SMS to the vehicle owner's registered mobile number after a missed ERP payment. You then have five days from the date that SMS is sent to pay the outstanding toll. Settle within those five days and the $10 administrative charge is waived entirely. You pay only the ERP amount.
The catch is that the SMS goes to the Singapore-registered mobile number tied to your Singpass profile. If that number is stale, you never get the alert, the five days lapse, and the $10 charge attaches by default. Updating your contact number on Singpass is the free insurance policy here.
Once the grace period closes, LTA mails a physical notice of ERP violation. At that point the bill is the ERP charge plus the $10 administrative charge, and the cheap window is gone.
Every channel below pulls the same outstanding amount from LTA's system, so there is no cheaper venue once a charge exists. The only money saver is timing, not the channel. Pick whichever is fastest for you and pay before the five days run out.
The OneMotoring portal is the canonical route. Log in, open Digital Services, then Pay LTA Fines and ERP Charges. You can settle with PayNow via SGQR or eNETS debit. AXS is the offline-friendly alternative through its kiosks, the m-Station app and the AXS website.
| Channel | How to access | Payment options | Best for |
|---|---|---|---|
| LTA OneMotoring | Digital Services > Pay LTA Fines and ERP Charges | PayNow (SGQR), eNETS debit | Fastest, Singpass login |
| AXS Stations | Kiosk, m-Station app, AXS website | NETS, card, eNETS | No Singpass needed |
| OBU app notification | Tap the missed-payment alert in the OBU app | Linked payment method | ERP 2.0 vehicles |
| Backend service auto-deduct | EZ-Pay or vCashCard backend | Charged to linked account | Preventing the fine entirely |
The escalation ladder is steep relative to the original toll, which is exactly why drivers regret ignoring the SMS. A 70-cent gantry pass can balloon into a $70 fine and then a court matter, all over a delay rather than a deliberate offence.
There is a second sting most people miss. Outstanding ERP payments block your vehicle services. LTA can deny renewal of road tax, transfer of registration and related transactions until the amount is cleared. If you are timing a road tax renewal or selling the car, an unpaid ERP charge quietly jams the whole process.
| Stage | What you owe | Timing |
|---|---|---|
| Within 5-day SMS grace | ERP charge only | Days 1 to 5 from SMS |
| After grace, on letter | ERP charge + $10 admin charge | After day 5 |
| Unpaid violation | $70 fine | If letter goes unsettled |
| Court referral | Court-determined penalty | Around 28 days unpaid |
| Service block | Above + frozen vehicle services | Until fully cleared |
Paying an ERP fine well is good. Never owing one is better. The recurring trigger is an insufficient or unread balance at the gantry, so removing the manual top-up step removes the risk.
Backend payment services do exactly that. NETS vCashCard and EZ-Pay charge your ERP to a linked account after the fact rather than relying on stored value, so a flat card balance never causes a miss. They cover up to three vehicles each, and EZ-Pay has no subscription fee. For ERP 2.0 vehicles, the OBU app now flags a missed payment and lets you settle from the alert before it ever reaches the five-day clock.
ERP 2.0 replaces the old in-vehicle unit with a satellite-based On-Board Unit. The pricing logic still runs on virtual gantries during the transition, and the same five-day grace rule and $10 administrative charge apply when a payment is missed.
What is genuinely new is the in-app safety net. The OBU app surfaces a missed-payment notice and a one-tap settle option, which means a connected driver can clear the toll within hours rather than discovering it on a letter weeks later. The infrastructure is shifting, but the cheapest way to pay an ERP fine has not: settle fast, settle inside five days, and the $10 never appears. For the wider rollout picture, see our explainer on ERP 2.0 and the OBU.
Five days from the date LTA sends the SMS notification of your missed ERP charge. Pay within that window and you owe only the original toll, with no $10 administrative charge added on top of the amount.
There is no cheaper channel once a charge exists, because every option pulls the same amount from LTA's system. The only way to pay less is timing: settle within the five-day grace period to avoid the $10 administrative charge entirely.
An unpaid violation escalates from the ERP charge plus $10 to a $70 fine, and around 28 days unpaid it can become a court summons. LTA also blocks vehicle services like road tax renewal and registration transfer until you clear it.
The alert goes to the Singapore-registered mobile number on your Singpass profile. If that number is outdated you will not receive it, the five-day grace period lapses unnoticed, and the $10 administrative charge attaches by default to the bill.
