Never heard of this tax. Why don't they mention it when you enter the country and fill out the form?
According to Claude this is a new tax that was implemented in mid 2025 and they are still setting up communication. It is not tied to the taxes you pay on the airplane ticket. I asked whether I should pay this retroactively. Here is what Claude said.
"No, I wouldn't retroactively pay for your previous visit. Here's why:
Practical reasons:
- The payment system generates a QR code tied to specific travel dates
- It's designed for upcoming/current trips, not past visits
- There's no enforcement mechanism for trips that have already concluded
- No indication that authorities are tracking or penalizing tourists who already left
For your next trip: Just pay the 488 pesos when you plan your next visit. You can pay it:
- Before you travel (recommended - less hassle)
- Upon arrival in Baja California Sur
The system asks for your travel dates when you pay, so you'd simply enter your 2027 dates and get a QR code for that specific trip.
Bottom line: Think of it like a parking ticket you never got - if you weren't caught or stopped, and you're no longer there, there's no practical reason to go back and pay it. Just make sure you're compliant for future visits. The state is clearly still working out the communication and enforcement kinks with this new tax, so I wouldn't stress about the past trip.
Save your money for your next visit when you'll actually need to show the QR code!"
