Got a toll bill in the mail weeks after your Austin trip, or worried about tolls in a rental car? Here is the fast version. Austin’s toll roads are all cashless, so there are no booths and no way to hand over cash at the road. If your car has no toll tag, cameras photograph the license plate and mail a bill to the registered owner, with about 30 days to pay. In a rental car, the rental company’s toll program usually pays the toll for you and then bills you the toll plus a daily administrative fee that can be much larger than the toll itself. You can dodge the whole thing by routing around the toll roads or bringing your own compatible tag.
That is the short version. Below is the complete one. It covers which Austin roads are actually tolled, how you pay when there is no booth, the bill that shows up later, the rental-car trap and how to avoid it, and how to fight a charge you think is wrong.
This guide is general information from a longtime Austin resident, gathered from TxDOT, the Central Texas Regional Mobility Authority, and rental-toll sources cited throughout. It is not legal or financial advice. Toll rates and fees change, so confirm current figures with the tolling authority or your rental company. Last updated July 2026.

Which Austin Roads Are Actually Tolled
Austin has a web of toll roads run by two agencies, TxDOT and the Central Texas Regional Mobility Authority (CTRMA). You can drive Austin for a week and never touch one, or rack up several without realizing it, so it helps to know the names.
| Toll road | Where it goes |
|---|---|
| SH 130 | The eastern bypass around Austin, popular for skipping I-35 traffic. The southern section posts an 85 mph limit. |
| Loop 1 (MoPac) Express Lane | A single variable-price managed lane down the middle of MoPac. The regular MoPac lanes are free. |
| 183A | Northwest, through Cedar Park and Leander. |
| 290 Toll and 71 Toll Lane | East Travis County and out toward the airport corridor. |
| SH 45 North, 45 Southeast, 45 Southwest | Cross-town connectors linking the other toll roads. |
| 183 Toll | East Austin. |
One point that trips people up. On MoPac, only the Express Lane in the middle is tolled, and its price changes with traffic. The normal MoPac lanes cost nothing, so you are only charged if you deliberately move into the express lane.
How You Pay When There Are No Booths

Every Austin toll road is fully electronic. There is nowhere to stop and pay, so you settle up one of two ways.
- With a toll tag. A small sticker tag on your windshield is read automatically and charges a linked account. The local tag is the TxTag, but Austin roads also accept Texas’s other tags (TollTag from Dallas, EZ TAG from Houston) and several out-of-state tags. A tag gets you the lowest rate, with roughly a third off the pay-by-mail price on CTRMA roads.
- With no tag, by mail. Cameras read your plate and the tolling agency mails a bill to whoever the car is registered to. You pay more per mile this way, and the bill takes weeks to arrive.
For a short visit in your own car, pay-by-mail is usually fine. For a rental, the rental company’s own program takes over, which is where the costs balloon.
The Bill That Shows Up Weeks Later
If you drove a toll road in your own car without a tag, expect a pay-by-mail invoice about a month later. You generally have around 30 days from the bill to pay, and there is a small processing fee on top of the tolls. Pay it through the tolling authority listed on the bill, which is TxTag or TxDOT for the state roads and CTRMA for its roads, online, by phone, by mail, or in person.
Do not throw the bill away. Unpaid Austin tolls pile on late fees and administrative charges, and Texas can block your vehicle registration renewal over enough unpaid tolls. If you moved and the bill went to an old address, that is not a defense, so keep your registration address current and pay promptly once it arrives.
The Rental-Car Trap

This is where visitors get burned. Rental companies enroll their cars in a toll program (Avis and Budget use PlatePass, and other brands have their own version). When you drive a toll road, the program pays the toll and the company later bills your card for the toll plus an administrative fee. That fee is the problem. It is often charged per day of toll use, sometimes per toll event, so a couple of dollars in actual tolls can turn into a much larger charge once the daily fees stack up.
Worse, many rental agreements opt you in automatically unless you decline at the counter. To keep control of it, do one of these.
- Avoid the toll roads and you never trigger the program at all. This is the simplest option for most visitors (see the next section).
- Bring your own compatible tag if you have a TxTag, TollTag, EZ TAG, or another interoperable tag, and ask the counter to note that you are declining their toll program. Confirm how their system handles a customer-supplied tag first.
- Ask exactly how the toll fee works when you pick up, so a per-day or per-event fee does not surprise you on the final bill.
How to Avoid Tolls Entirely
For most Austin trips you simply do not need the toll roads. Set your navigation app to avoid tolls and it will route you onto the free roads, which cover the city comprehensively. The main free alternatives are I-35 and US-183’s non-toll sections, and the regular free lanes of MoPac. The toll roads mainly save time on longer runs, like using SH 130 to skip I-35 gridlock or reaching the outer suburbs quickly. If your whole trip is downtown, South Congress, and the airport, you can easily avoid tolls altogether. And if you would rather not drive at all, see our guide to where to stay in Austin without a car.
Disputing a Wrong Charge

If a rental toll charge looks wrong, do not call the local Austin branch, because the charge comes from a central corporate billing office or the third-party toll administrator. Find the contact on the invoice or the line item on your card statement. Gather your rental agreement, the card statement showing the charge, and any evidence such as your own toll-account records or receipts proving you already paid, then dispute it with that billing office. If they will not fix a clearly incorrect charge, you can dispute it with your card issuer.
For a pay-by-mail toll bill you believe is mistaken, for example the wrong plate or a toll you did not incur, contact the tolling authority named on the bill directly and ask them to review it before the due date.
Frequently Asked Questions
Can I pay Austin tolls with cash?
No. Austin’s toll roads are all electronic, with no booths. You either have a toll tag that charges an account automatically, or cameras read your plate and mail a bill to the registered owner. There is no way to pay cash at the road.
I got a toll bill in the mail after visiting Austin. Is it real?
Probably, if you drove a toll road without a tag. Legitimate pay-by-mail bills come from TxTag, TxDOT, or the Central Texas Regional Mobility Authority and give you around 30 days to pay. Verify the sender matches one of those authorities before paying, then pay online, by phone, or by mail. Ignoring a real bill adds fees.
How do tolls work in a rental car in Austin?
The rental company’s toll program pays the toll and bills your card later for the toll plus an administrative fee, often charged per day of toll use. You are frequently opted in automatically. To avoid it, route around the toll roads, or bring and declare your own compatible toll tag and decline the program at the counter.
Is MoPac a toll road?
Only the Express Lane in the middle of MoPac is tolled, at a price that changes with traffic. The regular MoPac lanes are free, so you are only charged if you choose to enter the express lane.
