Yes, almost all taxis in Singapore accept credit and debit cards, including Visa, Mastercard, and American Express, as well as mobile payments like Apple Pay and Google Pay. However, there is a significant catch: most taxi companies (like ComfortDelGro) apply a 10% administrative surcharge plus GST on top of the total metered fare for all credit card payments. If you use "NETS" or local QR-based payments (like GrabPay or PayLah!), the surcharge is much lower—typically a flat fee of around $0.30. Because of these extra fees, many locals still prefer to pay in cash or use the EZ-Link card (the transit card), which most taxis also accept. If you book a taxi through an app like CDG Zig or use a rideshare service like Grab, Gojek, or Tada, you can link your credit card directly to the app to pay the "flat fare" without the 10% administrative fee. This is often the most cost-effective way for travelers to pay for private transport in the city without carrying physical cash.
