Money in Mexico: taxes, ATMs, tipping

Here is the thing a friend who lives here would tell you before you land: Mexico runs on cash more than you expect, cards work great in the places you’d assume, and the single most expensive money mistake is not a scam or a pickpocket. It happens at the ATM, in broad daylight, when the machine politely offers to help you.

The ATM trap, and how to dodge it

When a Mexican ATM asks whether you want to be charged in your home currency or in pesos, always choose pesos. Always. That friendly “we’ll convert it for you” screen is dynamic currency conversion, and it skims roughly 5 to 12 percent off the exchange rate, approximate but consistently bad. Decline the conversion, let your own bank do the math, and you keep that money.

A few more habits that save real cash:

Use bank-branded ATMs inside a branch or a guarded lobby. BBVA, Santander, Banorte, HSBC, and Scotiabank are everywhere and reliable.
Avoid the standalone off-brand machines in tourist zones, especially ones labeled Banjercito-style tourist ATMs or generic units in OXXO and airport corridors. Their per-withdrawal fee runs higher, often around 100 to 200 MXN per pull, approximate.
Withdraw larger amounts less often. Most machines cap you around 6,000 to 9,000 MXN per transaction, approximate, so pull near the ceiling to spread that fixed fee.
Tell your bank you’re traveling, and bring a second card. Skimming exists; a backup in the hotel safe means one frozen card doesn’t end your trip.

Exact fees and caps drift, so the site verifies current figures — treat the numbers here as the shape of the thing, not the receipt.

Cash versus card, region by region

Cards, tap-to-pay, and Apple or Google Pay are fine across Mexico City, Guadalajara, Monterrey, and the resort spine of the Riviera Maya. Restaurants, supermarkets like Soriana and Chedraui, and chain pharmacies all take plastic without blinking.

Cash is still king the moment you step off that spine. You need pesos for colectivos (shared vans) and second-class buses, for tianguis street markets, for taco stands and torta carts, for small-town fondas, for tips, for the bathroom attendant with the plate of coins, and for artisan stalls in places like Oaxaca, San Cristóbal de las Casas, or the pueblos around Pátzcuaro. A workable rule: carry 500 to 800 MXN in small bills on you, approximate, and break the big 500-peso notes at an OXXO or Kiosko by buying water, because taquerías rarely have change for them.

One quiet detail locals know: OXXO and other convenience stores double as a cash network. You can pay for many things — bus tickets, some tours, online orders — in cash at the counter using a barcode or reference number. It’s how a lot of Mexico moves money.

The taxes that are real

Two travel taxes actually matter, and both are legitimate — not the invented “fees” a bad taxi driver might float.

Quintana Roo visitor tax (Visitax). If you fly into Cancún, Tulum, Playa del Carmen, or anywhere in Quintana Roo, the state charges a per-visitor tourism tax. The current amount is verified on this page’s fact panel; budget for it as a small one-time charge, roughly a few hundred pesos per person, approximate. Pay it on the official state portal before you leave or during your stay. Enforcement at the airport has been tightening, so keep the QR confirmation on your phone. Ignore the copycat websites that charge a markup — use the official Quintana Roo government site only.

Federal departure and tourist fees. Most international flights bake the tourist card (FMM-related) and airport departure charges into your ticket price already, so you usually won’t pay separately at the gate. Land border crossings can be different — if you’re entering by land and staying beyond the border zone, you may pay a tourist fee at a Banjercito window. See entry and paperwork for how the immigration side works.

What is not a real tax: any “tourist fee” a driver, timeshare tout, or street “guide” invents on the spot. There’s no legitimate cash tax collected curbside.

Tipping without overthinking it

Tipping (propina) here is real but calmer than in the US. A cheat sheet:

Sit-down restaurants: 10 to 15 percent. Check whether servicio is already added on the bill in some tourist spots so you don’t double-tip.
Baggers at the supermarket: these are often unpaid workers living on tips — 5 to 10 MXN is kind and normal.
Gas station attendants: Mexico’s stations are full-service (no self-serve at Pemex or the newer BP and OXXO Gas stations). Tip 5 to 20 MXN, more if they clean your windshield or check tires. Also: watch the pump reads zero before they start, a classic short-change move.
Hotel housekeeping and bellhops: 20 to 50 MXN, approximate.
Tour guides and dive masters: 10 to 15 percent of the tour, or a couple hundred pesos for a good day.
Street food and taco stands: no tip expected unless there’s a jar out; rounding up is plenty.
Taxis: locals generally don’t tip metered street taxis; round up if you like. Uber and DiDi have an in-app tip option.

What things actually cost

Real numbers help you sanity-check, all approximate and regional — Tulum and Los Cabos run far pricier than Mérida, Puebla, or Guanajuato.

Taco al pastor from a street cart: roughly 15 to 30 MXN each.
Comida corrida (the set lunch that is Mexico’s best budget move): around 90 to 160 MXN for soup, a main, tortillas, and agua fresca.
Mid-range dinner for two with drinks: roughly 500 to 1,000 MXN.
Domestic beer or a michelada: about 40 to 90 MXN depending on the place.
Long-distance bus: intercity fares vary widely; ADO covers the south and Yucatán, ETN and Primera Plus cover the center-west with big reclining seats. A four-to-five-hour first-class leg often runs a few hundred pesos, approximate. More in getting around.
Airport to town by official taxi or Uber: frequently 200 to 600 MXN depending on city and distance.

Apps and small tricks locals use

Download these before you go: Uber and DiDi for rides in most cities (DiDi is often cheaper and covers more mid-size towns), your bank’s app to watch charges in real time, and a currency app so you can eyeball the peso rate. Mercado Libre and its Mercado Pago wallet are Mexico’s Amazon-plus-PayPal if you end up buying anything locally.

A last few friend-to-friend beats. Keep a slim day wallet with a few hundred pesos and one card, and leave the rest at the hotel — you’ll flash less cash. Break big notes early and often. Don’t change money at the airport currency booths; the rate is poor. And if a card reader is ever carried away from your table “to the back,” that’s your cue to go with it or pay cash. None of this is scary — it’s just how a peso-smart traveler moves.
