Whether you have to pay a "fee" to leave Mexico depends on how you entered the country and what is included in your airline ticket. Most international tourists arriving by air have the DNR (Derecho de No Residente) or "Tourist Tax" (roughly $35–$40 USD) already bundled into the price of their airfare. In this case, you don't pay anything extra at the airport. However, if you are leaving Mexico by land (e.g., crossing back into the U.S. or into Belize) and you stayed for more than seven days, you are legally required to pay this fee at the border if you didn't pay it when you entered. Furthermore, some Mexican states, most notably Quintana Roo (home to Cancun and Tulum), have implemented an additional local tourism tax called "Visitax" (approx. $11 USD). While this is technically required for all international visitors, enforcement at the airport departure gates is inconsistent. To avoid any last-minute stress or being pulled aside by immigration officials, it is wise to keep a digital or paper copy of your airline "Tax Breakdown" to prove the federal fee has already been paid, as being forced to pay twice is a common frustration for unaware travelers.
