In situations where the carrier does not facilitate the collection of the Exit Tax remember to set aside US$29.00 each to purchase it at the airport prior to check-in.
As an extra measure of personal safety, travelers should always keep a few dollars handy for unforeseen circumstances.
Being able to prove the Exit Tax is paid prevents unnecessary delays and unwanted expenses.
Refunds
Be Warned! Once the Exit Tax has been collected, there is no known method of collecting a refund.
Find out if the Exit Tax is included in your ticket beforehand. Request a breakdown of all charges included in the ticket price. This breakdown should be photocopied; keep the copy attached to your other travel documents. Information printed on the ticket is sometimes very difficult to understand (even by them); try explaining it to someone speaking a foreign language.
If you choose to leave Costa Rica by road then the Exit Tax is only USD 7.00; but that has another set of challenges.
