What New FASTag Time Windows Mean for Toll Payments 2025
Understand NHAI’s latest FASTag time window update and its impact on toll payments.
In February 2025, the National Highways Authority of India (NHAI) introduced a new system for FASTag transactions, adding a “time window” feature. This change was made to reduce toll errors, avoid double deductions, and make toll payments smoother for all drivers in India.
If you use FASTag for daily travel or long highway drives, it’s important to understand what this update means and how it affects your toll payments.
What Is a FASTag Time Window?
Earlier, when a vehicle crossed a toll plaza, the FASTag system would try to deduct the toll amount instantly. If there was a delay from the bank or the balance was low, the transaction often failed — causing confusion and long queues.
To solve this, NHAI introduced a “time window” — a short period during which your FASTag remains active for verification and payment retries. This window ensures your toll payment goes through even if there’s a small delay or connection issue.
In simple terms, the FASTag time window allows your tag a little extra time to process payments, rather than rejecting them immediately.
Why Did NHAI Add This New Rule?
The time window update was introduced following several complaints from vehicle owners regarding double charges, slow toll lanes, and FASTag blacklisting without reason.
With millions of vehicles now using FASTag, NHAI needed a more reliable process that:
Reduces technical errors and payment failures.
Allows time to recharge in case of low balance.
Prevents multiple deductions when vehicles pass nearby plazas quickly.
Keeps toll lines moving smoothly without manual checks.

How the New FASTag Time Window Works
When your vehicle approaches a toll booth, your FASTag is scanned by the automatic reader. If the balance is available, the amount is deducted normally.
But if the payment doesn’t go through because of a bank delay or low balance, the system keeps your FASTag active for a few more minutes. During this period, it will try again automatically to process the payment.
If you recharge your wallet during this time, the toll is deducted successfully without any manual steps.
This small window helps avoid rejections and unnecessary blacklisting of valid tags.
What Happens If You Don’t Recharge in Time
If your FASTag has insufficient balance and you don’t recharge within the given time, the tag will be marked inactive.
Once the window expires:
The toll system stops accepting your tag.
You may need to pay double the toll amount in cash or via UPI as a penalty.
Repeated incidents can lead to the temporary blacklisting of your vehicle’s tag.
That’s why it’s always better to keep your FASTag wallet ready with enough balance for at least two toll transactions.
How This Rule Helps Drivers
The FASTag time window update is meant to make toll travel faster and more reliable. It reduces technical issues that used to frustrate daily commuters.
Here’s how it helps:
Fewer payment failures at toll plazas.
No more duplicate charges when crossing multiple booths close together.
Less waiting time since the system doesn’t need manual approval.
Automatic correction for failed deductions or delays.
In short, it saves both time and stress for highway drivers.
How to Check If Your FASTag Is Working Properly
You can check your FASTag activity or payment status easily:
Visit the NHAI FASTag portal at fastag.ihmcl.com and log in to see recent transactions.
Use your issuing bank’s FASTag app (ICICI, HDFC, Paytm, etc.) to check the latest payment history.
Check SMS alerts — every successful or pending deduction is notified instantly.
If you see a “retry initiated” message, it means your tag is in its active time window and will try to deduct again automatically.
What To Do If Your FASTag Payment Fails
If your FASTag didn’t work even after waiting for a few minutes, here’s what you can do:
Don’t pay cash immediately; wait and check if the deduction happens within 10 minutes.
If no SMS or debit is shown, pay through UPI or cash and keep the toll receipt.
Report the issue at ihmcl.co.in with your vehicle number, toll name, date, and time.
Refunds for wrong or failed transactions usually come within 3–5 working days.
Simple Way to Avoid Such Problems
The easiest way to stay safe is to enable auto-recharge through your UPI or bank app. When your balance drops below a set amount, it recharges automatically — keeping your tag active even during the time window.
You can also check your FASTag balance before long trips to make sure it’s above ₹500 or more, depending on your regular toll usage.
