How to Buy a Car in Texas as a Mexican Resident — The Complete Guide
A step-by-step guide for Mexican nationals looking to purchase a vehicle in Texas — covering dealerships, required documents, the sales tax exemption, and how to bring the car across the border without surprises.
Every year, tens of thousands of Mexican nationals make the trip to Texas to buy a car. Texas dealerships — especially along the border corridor — are well-equipped to serve this market, with Spanish-speaking sales staff and experience handling cross-border transactions.
This guide explains exactly how to do it right, from the moment you walk into a dealership to the moment you complete the import process on the Mexican side.
If you’re still deciding whether buying in Texas makes financial sense compared to purchasing in Mexico, our partners at Concesionarios de Autos have a detailed cost comparison from the Mexican buyer’s perspective that’s worth reading first.

This is where most buyers get tripped up. Here’s exactly what you’ll need at the dealership and later at the border crossing:
Step 2 — The Full Process, Explained
- Research Your Vehicle Before Leaving Mexico Search online inventory on dealership websites — most major Texas dealers publish live stock. Confirm the exact trim, color, and mileage (for used cars). For the import to be eligible in Mexico, the vehicle must generally be 10 model years old or newer. Verify the current regulation with your customs broker before making any commitments.
- Contact the Dealership Ahead of Time Call or email before you drive up. Ask if they have experience with Mexican buyers (“international sales” or “cross-border buyers”). Many border-area dealers have bilingual staff dedicated to this market. Confirm upfront that they can issue a paper title rather than an electronic one — this is non-negotiable for the Mexican import.
- Arrange Your Payment Method If bringing cash, note that amounts over $10,000 USD must be declared at U.S. Customs when entering the country. Wire transfers from a Mexican bank are the cleanest option for larger purchases. Avoid cashier’s checks from unfamiliar institutions — dealers are required to report suspicious transactions under federal law.
- Claim the Texas Export Sales Tax Exemption This is the tip most buyers don’t know: if you’re a Mexican resident buying a vehicle to export, you may qualify for a full Texas sales tax exemption. Mention this before the paperwork begins and ask the finance office to complete Texas Form 14-312. On a $30,000 vehicle, this saves you ~$1,875 in state tax. Not all dealers know this process — be prepared to explain it calmly.
- Complete the Purchase and Get Your Transit Plates After signing, the dealer will issue a Texas Transit Tag — a temporary license plate valid for 30 to 60 days. This is your legal authorization to drive the vehicle in Texas and cross the international bridge. Keep it displayed in the rear window at all times.
- Drive to the Border and Hire a Customs Broker When you reach the crossing, you’ll need a licensed Mexican customs broker (agente aduanal) to process the import. They operate from offices right at the international bridges and handle the paperwork, duty calculation, and clearance. Budget 2–5 business days and approximately $3,000–$8,000 MXN for their services, separate from the import duties.
- Pay Mexican Import Duties and Complete Registration The main import costs are: the ISAN tax, an import tariff (roughly 5–20% depending on vehicle origin and category), the DTA customs processing fee, and 16% IVA. Your customs broker calculates exact amounts based on the vehicle’s declared value. Once cleared, you register the vehicle normally in Mexico.

Best Texas Cities for Mexican Car Buyers
Location matters. These are the top Texas markets for cross-border purchases, with their corresponding Mexican border crossings:
Pro Tips for a Smooth Purchase
Always request a paper title
Texas has moved to electronic titles, but Mexico still requires a physical original. Say “paper title” or “original title” explicitly when completing the sale. If there’s a lien, ensure it’s released before you take delivery.
Run a VIN history report
For any used vehicle, request a Carfax or AutoCheck report. Flag flood damage, salvage title, and accident history. Vehicles with a “Salvage” or “Rebuilt” title cannot be imported to Mexico — full stop.
Don’t pay Texas sales tax
Ask the finance office about the Texas export sales tax exemption (Form 14-312) before paperwork starts. As a Mexican resident exporting the vehicle, you likely qualify. This can save $1,000–$2,500+ depending on the vehicle.
Get Mexican car insurance before crossing back
Your Mexican auto insurance is not valid in the U.S., and U.S. dealer plates are not covered by most Mexican policies. Purchase short-term Mexican car insurance (available at most border crossings) for the return trip.
Line up your customs broker before you travel
Contact an agente aduanal in your target border city before you even buy the car. They’ll tell you exactly which documents to have the dealer prepare. This prevents costly last-minute surprises at the bridge.
Verify the manufacturer warranty
Ford, GM, and Ram generally offer warranties valid throughout North America. Toyota and Honda vary by model and year. Always confirm in writing before signing — a warranty that doesn’t cover Mexico is a significant drawback.
