No, Singapore taxis do not accept US Dollars (USD) as a direct form of payment in 2026. The official and only accepted physical currency for cash payments is the Singapore Dollar (SGD). If you attempt to pay with USD cash, the driver will likely politely decline, as they cannot easily deposit or exchange it at a standard bank without fees. However, Singapore's taxi fleet is among the most technologically advanced in the world, meaning you rarely need cash at all. All taxis (including ComfortDelGro, Trans-Cab, and SMRT) are equipped with terminals that accept international credit and debit cards (Visa, Mastercard, Amex), as well as mobile wallets like Apple Pay and Google Pay. If your USD is in a bank account linked to your phone or a travel card, you can pay seamlessly at the prevailing exchange rate set by your bank. For the best experience, travelers are encouraged to use ride-hailing apps like Grab, Gojek, or Tada, where you can link your international card once and never worry about currency conversion or cash during your trip around the city.
