There are plenty of ATM's and money changers at the airport on arrival, so purchasing TWD before leaving home is not really necessary. If you do wish to change money before you arrive, be aware that the rates will not be as good as those you will get in Taiwan so it is probably worth changing as little as possible.

In 2026, it is generally not necessary to exchange significant amounts of money before you arrive in Taiwan, as you will typically find much better exchange rates at the airport or local banks upon arrival. The New Taiwan Dollar (NT$) is the only currency accepted for daily transactions; foreign currencies like USD or RMB are not used. Upon landing at Taoyuan (TPE) or Songshan (TSA), you will find 24-hour currency exchange counters that are highly regulated and offer fair market rates with minimal fees. While major hotels and department stores in cities like Taipei accept credit cards, Taiwan still has a strong cash-based culture, especially at night markets, traditional eateries, and for transportation. To ensure a smooth start, you might exchange a small "starter" amount (e.g., $50) at home for immediate needs like an EasyCard or a taxi, but for the bulk of your funds, utilizing the ATMs at Taiwan’s ubiquitous 7-Eleven or FamilyMart convenience stores is the most efficient and cost-effective strategy for international travelers.
