Do I Need EZ TAG for Houston? 2025 Update
No, you don't need an EZ TAG to drive on Houston toll roads - but you'll pay 50% more without one. Houston converted to predominantly electronic tolling with multiple payment options, but electronic transponders provide the best rates and convenience.
Key Reality: Without an electronic tag (EZ TAG or TxTag), you'll pay Non-Tag rates calculated at 50% surcharge over electronic rates plus additional administrative fees. For regular Houston commuters, this can add hundreds of dollars annually.
2025 Major Update: HCTRA took over TxTag customer service and billing operations for Houston and Austin areas as of November 9, 2024, consolidating toll management under one authority while maintaining road ownership by individual agencies.

Frequently Asked Questions
Can I avoid Houston tolls completely?
Yes, but with significant time penalties. Houston's toll-free surface roads and freeways like I-610, I-45, and US 59/I-69 provide alternatives, but add 20-60 minutes to most cross-city trips during peak hours.
What happens if I don't pay Houston tolls?
Unpaid tolls escalate quickly: toll amount + $1.04 processing fee (initial notice), then $10 administrative fee per violation. HCTRA may send accounts to collections after 45 days, and habitual violators may face vehicle registration blocks.
Do I need different tags for different Houston toll roads?
No, EZ TAG and TxTag work on all Houston area toll roads. However, you get a 10% discount with EZ TAG on HCTRA roads (Sam Houston, Hardy, Westpark, Tomball).
What's the difference between EZ TAG and TxTag now?
As of 2025, HCTRA manages both systems. Existing TxTags continue working, but new customers receive EZ TAGs. Both provide the same rates, but EZ TAG offers 10% discount on HCTRA roads.
