How to pay Austin tolls

Austin tolls are managed by the Central Texas Regional Mobility Authority (CTRMA), and you can pay them three ways: through a TxTag account, by mail after receiving an invoice, or through the online toll payment system at tolls.ctrma.org. Most drivers use TxTag because it's the cheapest option — you get a discount on every toll you pass through. If you don't have an account and drive a toll road without paying, CTRMA will photograph your license plate and send you an invoice weeks later, usually with a higher per-toll rate than TxTag holders pay.

The toll roads in Austin include the 290E Toll, 71 Toll, 183A Toll, and 45SW Toll. Each charges different amounts depending on the time of day and traffic conditions — some roads use dynamic pricing, meaning the toll goes up during rush hour. You don't need to stop or interact with anything; the system reads your license plate or TxTag as you pass through.

Key Takeaways

  • TxTag is the cheapest way to pay Austin tolls and gives you a discount of roughly 30 to 50 percent compared to paying by invoice after the fact.
  • You can set up a TxTag account online at tolls.ctrma.org or by phone at 1-888-468-9824, and the tag itself arrives by mail in about 7 to 10 days.
  • If you don't pay a toll within 30 days, CTRMA sends an invoice to your address; if you ignore that, late fees and collection actions can follow.
  • Toll rates vary by road and time of day, with some roads charging more during peak traffic hours, so check the specific road before you drive.

Setting up a TxTag account

To open a TxTag account, go to tolls.ctrma.org and click "Manage Your Account" or call 1-888-468-9824. You'll need a valid driver's license or ID, a vehicle registration number, and a payment method — credit card, debit card, or bank account. The online process takes about 10 minutes. CTRMA will mail you a physical TxTag transponder, which typically arrives within 7 to 10 business days.

Once your tag arrives, mount it on the inside of your windshield (usually on the upper driver's side, following the instructions that come with it). The account starts working as soon as you set up it online, even before the physical tag arrives, so you can start getting the TxTag discount when ready. Set up automatic replenishment so your account doesn't run low — you can choose to add money when your balance drops below a certain amount, or add a fixed amount on a schedule.

If you drive multiple vehicles, you can add up to five tags to one account. Each tag is tied to a specific vehicle's license plate, so CTRMA knows which car went through the toll.

Paying tolls without a TxTag account

If you don't have a TxTag and drive through a toll road, CTRMA's cameras photograph your license plate. Within 30 days, you'll receive an invoice by mail at the address on your vehicle registration. The invoice shows which toll road you used, the date, and the amount owed. Pay it online at tolls.ctrma.org, by phone at 1-888-468-9824, or by mail using the payment coupon included with the invoice.

The per-toll charge for paying by invoice is significantly higher than the TxTag rate — typically 30 to 50 percent more, depending on the road. For example, a toll that costs $0.50 with TxTag might cost $1.00 or more when paid by invoice. If you drive tolls regularly without a TxTag, the costs add up quickly, making it worth setting up an account.

Payment by invoice is meant for occasional drivers or visitors, not regular commuters. If you live in Austin or drive the toll roads frequently, TxTag saves money and eliminates the hassle of waiting for invoices.

What happens if you don't pay

If you receive an invoice and don't pay within 30 days, CTRMA sends a notice of delinquency. Ignore that, and the debt can be referred to a collection agency. Late fees and collection costs are added to your original toll amount. In some cases, CTRMA can place a hold on vehicle registration renewal through the Texas Department of Motor Vehicles, meaning you won't be able to renew your registration until the toll debt is paid.

The collection process is separate from criminal charges — unpaid tolls are a civil matter, not a criminal one in Texas. However, repeated non-payment or toll evasion (deliberately avoiding payment) can result in additional penalties. The simplest approach is to pay the invoice when it arrives or set up TxTag to avoid invoices altogether.

Toll rates and dynamic pricing

Austin toll rates vary by road and time of day. The 290E Toll, 71 Toll, 183A Toll, and 45SW Toll each have their own pricing structure. Some roads use dynamic pricing, meaning the toll increases during peak traffic hours (typically 7 to 9 a.m. and 4 to 6 p.m. on weekdays) and decreases during off-peak times. CTRMA adjusts rates to manage traffic flow — higher tolls during rush hour encourage some drivers to use alternate routes or travel at different times.

You can see current toll rates for each road on tolls.ctrma.org before you drive. The website shows the rate for the current time and lets you check rates for other times of day. TxTag holders pay the same rate as everyone else; the discount comes from not paying the invoice surcharge.

If you have a TxTag account, you can set up notifications to alert you when your balance is low, so you're never caught off guard by a declined payment.

Disputing a toll charge

If you believe a toll charge is wrong — for example, you think you were charged twice for one passage, or the photo shows a different vehicle — contact CTRMA within 30 days of receiving the invoice. Call 1-888-468-9824 or use the dispute form on tolls.ctrma.org. Have your invoice number and any photos or evidence ready.

CTRMA reviews disputes and can issue a refund or credit if they find an error. The process usually takes 2 to 4 weeks. If you're disputing a charge on your TxTag account, you can also submit the dispute through your online account dashboard.

Frequently Asked Questions

Can I get a refund if I paid a toll by mistake?

Yes. Contact CTRMA within 30 days of the charge with your invoice or account details. If you can show the charge was an error — such as being charged twice for one passage — they will issue a refund or account credit. Disputes take 2 to 4 weeks to process.

What if I move out of Texas and still have a TxTag account?

You can keep your account open and continue using it if you return to Austin. If you no longer need it, close the account online or by phone, and CTRMA will refund any remaining balance to your original payment method within 7 to 10 business days.

Do I need a separate TxTag for each vehicle?

No. One account can hold up to five tags, each linked to a different vehicle's license plate. This is useful if your household has multiple cars that use the toll roads. Each tag gets the same discount rate.

Can I use my TxTag from another state on Austin toll roads?

TxTag is specific to Texas toll roads. If you have a tag from another state's toll system, it won't work on Austin roads. You'll need to set up a separate TxTag account for Austin tolls.

What if my TxTag is damaged or lost?

Contact CTRMA at 1-888-468-9824 or through tolls.ctrma.org to report it. They can deactivate the old tag and mail you a replacement, usually within 7 to 10 business days. There may be a small replacement fee depending on the reason for the replacement.
