If you drove a Texas toll road without an electronic tag, the toll authority photographed your license plate and will mail an invoice to the address on your vehicle registration. That system is called Pay By Mail, and it’s how to pay Texas tolls without a tag: wait for the bill and pay it, or look up your recent tolls online and pay them before the invoice ever arrives. Either way, you’ll pay more per trip than a tag holder, and ignoring the bill turns a small charge into a serious one.
How the Bill Finds You
Overhead cameras in every toll lane capture plates as vehicles pass. When no tag is detected, the system logs the plate, date, time, and location, then pulls the registered owner from state motor vehicle records and mails an invoice to the address on file.
That last part matters. If you’ve moved and haven’t updated your registration with the Texas Department of Motor Vehicles, the bill goes to your old address and the fees keep accruing while you’re unaware. Update your address before you drive, not after.
What You’ll Actually Pay
Pay By Mail rates run substantially higher than electronic tag rates, and the exact premium depends on which authority operates the road. On North Texas Tollway Authority roads, ZipCash (the Pay By Mail program) charges double the TollTag rate. A trip that costs $1.84 with a tag runs $3.68 through ZipCash.1NTTA. NTTA
On Central Texas Regional Mobility Authority roads, the markup is closer to 50 percent above the tag rate.2Central Texas Regional Mobility Authority.

The premium reflects the cost of processing plate images and mailing paper invoices. It applies to every transaction, so a few weeks of tag-free commuting can produce a bill much larger than drivers expect.
Paying Before an Invoice Arrives
You don’t have to wait for a bill. The three major Texas toll authorities each let you look up recent tolls by license plate through their websites:
- NTTA (Dallas–Fort Worth roads, including the Dallas North Tollway)1NTTA. NTTA
- HCTRA (Harris County roads, including the Sam Houston Tollway)3Harris County Toll Road Authority. HCTRA — Harris County Toll Road Authority
- TxTag (Austin-area and other state-operated roads)
You’ll need to know which authority runs the road you drove on. If you’re not sure, check all three portals. Paying early keeps administrative fees from stacking up if the invoice gets delayed or lost in the mail.
Paying an Invoice You’ve Received
A Pay By Mail invoice itemizes each transaction: plate, date and time, toll point, and amount. A due date is printed prominently, and the total at the bottom includes any administrative charges already applied. The envelopes look like junk mail, so open anything from a Texas toll authority.
The fastest way to pay is online through the issuing authority’s website, using the invoice number or your plate and a credit or debit card. Confirmation is immediate. Each authority also accepts payment by phone with a card.
To pay by check or money order, mail it to the address on the invoice and include the payment stub so the authority can match the payment to your account. Send it early enough to arrive before the due date; a payment postmarked late may still draw late fees. Some authorities run walk-in customer service centers, and a few partner with retail networks that accept cash payments at participating stores. Check the invoice or the authority’s website for current options.
Rental Cars Are a Trap
Most major rental companies enroll their vehicles in a toll billing program automatically. Unless you opt out at the counter, you’ll be charged through the rental company’s program rather than through the toll authority directly.
These programs generally come in two shapes. A flat daily fee charges you every day of the rental contract whether you drive a toll road or not, typically $3 to $15 a day and often capped around $90 per rental. A per-use model charges you only on days you actually hit a toll road, but adds a daily convenience fee on top of the toll itself. Either structure can easily cost more than paying the tolls yourself.
If you rent often, the cheapest approach is to keep your own TxTag, TollTag, or EZ TAG account and add the rental’s plate when you pick the car up, then remove it as soon as you return it. Tell the counter clerk explicitly that you’re declining the rental toll program. If you forget, Pay By Mail bills will go to the rental company, which passes them through to your credit card with an administrative surcharge.
Disputing a Bill That Isn’t Yours
Sometimes the wrong person gets the invoice. The toll authority holds the registered owner responsible until you show otherwise, so if you sold the vehicle before the toll date, loaned or leased it, or had it stolen, you need to document that.
File a dispute with the authority listed on the invoice, typically online, by email, or by mail. For a sold vehicle, send the bill of sale or plate surrender receipt. For a stolen vehicle, send the police report. For a leased vehicle, lease documentation may shift liability to the lessee. Review times vary, so follow up if you don’t hear back within a few weeks. Don’t ignore the bill during the dispute; late fees generally keep accruing unless the authority pauses them.
What Happens If You Don’t Pay
The consequences escalate in stages.
When the initial invoice goes unpaid, the authority sends a notice of nonpayment and adds administrative fees to the original toll. Those charges grow with each subsequent notice, and there’s no single statewide schedule, so the amount depends on which authority is billing you and how long the debt has sat.
Under Texas law, you become a “habitual violator” once you’ve been issued at least two notices of nonpayment covering 100 or more unpaid toll events within a single year and still haven’t paid.4Justia. Texas Transportation Code Title 6 Subtitle G Chapter 372 Subchapter C Occasional drivers rarely hit that threshold; daily commuters without a tag can cross it in a few months.
Once you’re designated a habitual violator, several things can happen:
- The authority can report your status to the Texas DMV, which blocks your vehicle registration renewal until you pay the tolls and fees.5Central Texas Regional Mobility Authority. Habitual Violator Program
- The authority’s governing body can prohibit your vehicle from operating on any of its toll projects. Driving on that road afterward is a misdemeanor.4Justia. Texas Transportation Code Title 6 Subtitle G Chapter 372 Subchapter C
- If you’re caught driving on a toll road after being banned and were already stopped once for the same violation, a peace officer can detain and impound the vehicle. Getting it back means paying towing and storage plus the outstanding tolls.6State of Texas. Texas Transportation Code 372.112 – Impoundment of Motor Vehicle
On county-operated toll roads, a separate Transportation Code provision makes toll evasion a misdemeanor punishable by a fine of up to $250 per violation, plus court costs.7State of Texas. Texas Transportation Code Chapter 284 – Causeways, Bridges, Tunnels, Turnpikes, Ferries You have the right to request a hearing within 30 days of receiving the habitual violator notice. If you don’t request one, the determination becomes final.
When a Tag Starts to Make Sense
Pay By Mail rates run roughly 50 to 100 percent above tag rates on every single trip. If you use toll roads even a few times a month, the markup adds up faster than most drivers expect. Tags are free to order from each authority’s website, and one tag works across Texas: an NTTA TollTag is accepted in EZ TAG and TxTag lanes and vice versa, provided the account is in good standing and the vehicle’s plate is on file.8NTTA.
