Domestic air travel within Mexico has a departure tax of approximately $8.50 U.S. per person. The peso equivalent changes periodically. This tax cannot be collected in advance and must be paid in Mexico. Note that this tax is not collected for domestic portions of international journeys, and applies only to tickets that are purchased in Mexico for travel within Mexico.

International air travel from Mexico carries a departure tax of $11.50 U.S. This tax is paid in Mexico, and under some circumstances may be included on tickets issued outside of Mexico (ask your airline for details). This tax is not paid by infants, but children two and over pay the full amount.

There is a sales tax of 15%. The tax applies to the purchase of most items and is paid by everyone, residents and visitors alike. Often this tax is "buried" in the total cost of restaurant bills, store purchases, and excursions.

This tax also applies to the purchase of airline tickets within Mexico for travel commencing in Mexico (10% for domestic travel and 2.5% for international travel). Prepaid tickets often need to include these taxes. Consult the airlines for details.
