In St. Croix, U.S. Virgin Islands, tipping your taxi driver is customary and expected, though it is not legally mandatory. The standard tip is typically 15% to 20% of the total fare, especially if the driver helps you with heavy luggage or provides local insights during the trip. It is important to know that taxi rates in St. Croix are "per person" and regulated by the VI Taxicab Commission, rather than being metered; for example, a trip from the airport to Christiansted might have a fixed rate, but you should still calculate the tip based on the total cost. If you are part of a large group, a smaller percentage per person (around 10-15%) is often acceptable. Because most taxi drivers in St. Croix are independent contractors who pay for their own fuel and vehicle maintenance—which are very expensive on the island—these tips make up a vital portion of their income. Always try to carry small bills in U.S. Dollars, as many drivers prefer cash, although some are now equipped to take cards or mobile payments via apps.
