Taiwan Airport Service Fee Checklist: How to Tell From Your Ticket Issue Date Whether You Owe NT$750

The airport service fee you pay when flying out of Taiwan (出境航空旅客機場服務費) is not something you queue up to pay at the airport. Airlines collect it with the fare, bundled into the taxes-and-fees line of your ticket. That design has one practical consequence: when the amount changes, the only reliable way to know which amount you paid is to open your own e-ticket, not to read a news headline.

This is a checklist for doing exactly that. It covers which date decides your rate (short answer: the ticket issue date, not the departure date), where the charge appears on an e-ticket, what to ask an airline before you change a flight, and how to claim the fee back if you end up not leaving Taiwan at all.

1. The fee schedule, in two steps

Under the Taiwan Ministry of Transportation and Communications (MOTC) announcement and Article 3 of the Regulations Governing the Collection of Airport Service Fees from Outbound Air Passengers (出境航空旅客機場服務費收費及作業辦法), the fee rises in two stages:

• Through 31 August 2026 — NT$500 per passenger (unchanged since 2015)
• 1 September 2026 to 31 August 2028 — NT$750 per passenger (a NT$250 increase)
• From 1 September 2028 — NT$1,000 per passenger

The collection mechanism is identical at every tier. The airline collects the fee together with the ticket (隨機票代收). Passengers holding a ticket that does not include the fee pay it at the airline check-in counter on the day of departure. In other words, most travellers settled this charge the moment they bought the ticket. The transfer and transit facility fee (轉機過境設施使用費) moves on the same two-stage timetable, up to NT$1,000. Note too that Article 2 of the same regulations exempts children under two years of age, diplomatic and official guests covered by a treaty, an agreement or Ministry of Foreign Affairs approval, and transit passengers joining a half-day tour arranged by the tourism authority; exempt passengers still present their documentation at check-in.

2. Your issue date decides the rate — not your flight date

The most common misreading is "I fly after 1 September, so I automatically owe NT$750." That is not quite the rule — and it is not only a press account. The airlines publish the condition themselves: EVA Air announces that for tickets issued on or after 1 September 2026 the Taiwan airport service fee (tax code TW) moves in two stages by travel date (NT$750 for travel from 1 September 2026 to 31 August 2028, NT$1,000 from 1 September 2028), and Cathay Pacific states that the new rate applies to tickets issued or reissued on or after 1 September 2026 and that the fee must be reconfirmed after any change. So a ticket issued before the increase keeps the old NT$500 rate even for a later flight — as long as the ticket is not altered.

The logic follows directly from section 1. The fee is not collected at the departure gate; it is fixed and collected at the moment of ticketing, alongside the fare. So the question is not when you travel but when your ticket was written.

One caveat worth keeping: the official MOTC release and Article 3 of the regulations set the rates and the periods they cover, but neither says which date decides your rate. The issue-date test comes from each carrier's own ticketing rules, and the wording differs between them — EVA Air pairs the issue date with the travel date, Cathay Pacific keys on the issue or reissue date. Read the notice published by the airline that issued your ticket. That is precisely why steps 3 to 5 below exist — the only certainty comes from the number printed on your e-ticket and a direct answer from your carrier.

3. Check your ticket: capture three date proofs at once

1. The ticketing confirmation in your inbox — find the email titled "e-Ticket Issued" or "Ticket Issued" from the airline or agency. Read the issuance line in the body, not the email timestamp. A booking that is merely held is not the same as a ticket that has been issued.
2. Date of Issue on the e-ticket — look at the header or the passenger block of the e-ticket PDF for "Date of Issue" (開票日). This is the official ticketing date. The 13-digit ticket number usually sits in the same area; capture both together.
3. The payment receipt date — your card authorisation date or the agency receipt. Payment and ticketing can be a day or two apart, and for a ticket written near the changeover date that gap is the whole question.

Keep all three as screenshots in one folder. If you later need to query the charge or file a refund, those three images turn a long conversation into a short one.

4. Find the charge in the taxes and fees breakdown

An e-ticket separates the Fare from Taxes / Fees / Charges. The Taiwan departure airport service fee appears there under tax code TW, labelled something like "TW — Airport Service Charge" or "Taiwan Airport Service Charge" depending on the carrier template.

• Where to look — the tax code list on the Taxes/Fees line. It typically reads as a code plus amount, such as "TW 750", or appears as its own row in an itemised tax table.
• Mind the currency — if you paid in USD, KRW or JPY, the TW line may be shown converted. In that case it will not match NT$500 or NT$750 exactly, so work backwards through the exchange rate and see which of the two it lands closest to.
• If the TW code is missing — on a ticket with a flight departing Taiwan, a missing TW line can mean the fee was not included. You would then pay it at the check-in counter on departure day, at whatever rate is in force that day.
• Round trips and connections — the fee attaches only to the segment leaving Taiwan, not to your inbound flight. Seeing just one TW entry on a return ticket is normal.

5. Three questions to ask your airline before you change anything

The issue date matters most when you touch the ticket. Changing a date or a route can trigger a reissue, and a reissue can write a new issue date. Before you confirm any change, get answers to these three — and screenshot the chat or note the call reference.

1. "If this ticket is reissued, will the NT$250 difference in airport service fee be collected?" — naming the amount stops the conversation from ending at a vague "you only pay the change fee."
2. "When would that difference be collected — at reissue, or at the counter on departure day?" — the timing tells you what to have ready: a card, or NT$ cash at the airport.
3. "Does the original issue date carry over, or does the ticket get a new one?" — a date revalidation and a full reissue are handled differently. Ask which one your change will be processed as.

6. Refunds: if you paid but never departed, you get all of it back

The fee is levied on passengers who actually leave the country. Accordingly, the regulations provide that a passenger who paid the fee but did not depart may claim a full refund, and the airline may not charge anything for processing it (Article 3). Unused tickets, no-shows and cancellations all qualify.

Where to file

• Bought directly from the airline — the airline customer service line, or the refund section of its manage-booking page
• Bought through an agency or OTA — file with the original seller that issued the ticket. Refunds are normally returned to the original payment method.

What to have ready

• A copy of the e-ticket showing the 13-digit ticket number and Date of Issue
• The page where the TW line appears in the taxes and fees breakdown
• The payment receipt or card statement entry
• Evidence that the ticket went unused — a cancellation confirmation, for example
• Bank or card details for the refund, if the seller asks for them

The part most people miss: refunds are not automatic — you have to ask. Cancelling a ticket does not send the airport service fee back on its own. Filing windows depend on ticket validity and seller policy, so submit the claim as soon as the cancellation is final.

7. Clearing up the misconceptions

• "Any flight after September costs more." → No. The test is the ticket issue date. A ticket issued before the increase and left untouched keeps the old rate, per the airlines' own notices.
• "It is a departure tax you pay at the airport." → No. As a rule it is built into the ticket price and collected by the airline. Counter payment is the exception, for tickets that did not include it.
• "The issue-date rule is just something the press inferred." → No. The official MOTC material sets only the rates and the periods they cover, but the issue-date test is written into the airlines' own tariff notices (EVA Air and Cathay Pacific among them). The wording varies by carrier, so settle it with your own airline's notice and your e-ticket.
• "Taxes are not refundable on an unused ticket." → This charge is different. If you did not depart, the full amount is refundable and no processing fee may be deducted.

8. A five-minute check the night before

Three things to re-verify before you head to the airport:

1. Issue date — read the Date of Issue on the e-ticket one more time and place it clearly before or after the effective date.
2. Tax breakdown — is the TW amount NT$500, NT$750, or absent? If absent, have a payment method ready for the counter, including some NT$ cash.
3. Change history — did you move a date or a route after booking, and was it processed as a reissue? If so, bring the screenshot of what the airline told you.

With those three settled, any counter conversation about an extra charge becomes a thirty-second exchange rather than an argument.

All of this needs a connection

Notice where these steps actually happen: in a taxi, in a check-in queue, at a boarding gate. Reopening an e-ticket PDF, pulling up the booking in an airline app, starting a support chat, submitting a refund form — every one of them needs data. Airport Wi-Fi tends to involve a captive portal and tends to drop exactly when the line starts moving.
