Taiwan does have a tax refund system, but it works differently from the United States

Taiwan's tax authority, the National Tax Bureau, processes refunds for taxpayers who overpay income tax during the year. The refund happens automatically if you file a tax return and the government determines you paid more than you owed. You do not need to request it separately — the refund is calculated as part of the filing process.

The main difference from U.S. refunds is timing and method. Taiwan's tax year runs from January to December, and most individual taxpayers file between May and June each year. Refunds are typically issued within one to three months after you file, depending on whether the tax authority needs to review your return or request additional documents.

Taiwan also has a withholding tax system similar to the U.S., where employers deduct income tax from paychecks throughout the year. If you work for a Taiwanese company, your employer withholds tax based on your salary. If that withholding exceeds what you actually owe, you receive the difference as a refund when you file.

Key Takeaways

  • Taiwan's National Tax Bureau automatically calculates and issues refunds if you overpaid income tax during the year.
  • The tax filing period runs from May to June each year, and refunds typically arrive within one to three months after filing.
  • Refunds are issued by bank transfer to the account you provide on your tax return, not by check or mail.
  • If you are a foreign resident or expat working in Taiwan, different withholding rules may apply depending on your visa status and tax residency.

How to file and receive your refund in Taiwan

You can file your tax return through the National Tax Bureau's online system, called Tax Administration Online Filing System (TAFS), or by paper form at a local tax office. Most residents file online because it is faster and you receive confirmation immediately. You will need your national ID number, income documents from your employer, and details of any deductions or credits you claim.

When you file, you provide a bank account number where the refund should be sent. The National Tax Bureau does not mail checks; refunds are deposited directly to the account you list. Make sure the account is in your name and that the bank details are correct, because errors can delay the refund by weeks.

If you file by paper, processing takes longer — usually four to six weeks before the tax office contacts you with the result. Online filing is processed faster, often within two to three weeks if no additional review is needed.

What triggers a tax refund in Taiwan

The most common reason for a refund is overpaid withholding tax. If your employer withheld more tax than you owed based on your actual annual income, the difference is refunded. This can happen if you changed jobs mid-year, took unpaid leave, or had lower income than your employer expected.

You may also receive a refund if you claim deductions or tax credits that reduce your tax liability below what was already withheld. Taiwan allows deductions for charitable donations, insurance premiums, education expenses, and dependent care, among others. If your deductions are large enough, they can push your refund higher.

Self-employed people and business owners can also receive refunds if they overpay quarterly estimated taxes or if their actual profit is lower than estimated. However, self-employed individuals file on a different schedule and may have different refund timelines.

Refund timelines and payment methods

Standard refunds issued after a routine tax return review typically arrive within one to three months. The National Tax Bureau processes returns in batches, so the exact timing depends on when you file and whether your return requires additional scrutiny.

If the tax office needs more information — such as proof of deductions, additional income documents, or clarification on reported amounts — they will contact you by mail or phone. You then have a set period (usually 30 days) to respond. This can extend the refund timeline by several weeks.

Refunds are always issued by direct bank transfer. The National Tax Bureau does not issue checks, wire transfers to foreign accounts, or alternative payment methods. If you do not have a Taiwanese bank account, you will need to open one before filing your return.

Special rules for expats and foreign residents

If you are a foreign national working in Taiwan on a work visa, you are generally subject to the same tax withholding and refund rules as Taiwanese citizens. However, your tax residency status matters. You are considered a tax resident if you have lived in Taiwan for more than 183 days in a calendar year.

Non-residents are taxed only on Taiwan-source income and may have different withholding rates. If you are a non-resident, your employer may withhold tax at a flat rate, and your refund calculation may differ. You should confirm your tax residency status with the National Tax Bureau before filing.

Some expats also have income from outside Taiwan — from a home country, freelance work, or investments. Taiwan taxes worldwide income for residents but only Taiwan-source income for non-residents. This affects whether you can claim foreign tax credits or deductions, which in turn affects your refund amount.

What to do if your refund is delayed or missing

If you filed your return and the expected refund timeline has passed without payment, first check the status of your return through the National Tax Bureau's online system. You can log in with your ID number and see whether your return is still under review, approved, or if there is a note requesting additional information.

If your return shows as approved but you have not received the refund, verify that the bank account information you provided is correct. Refunds are sometimes delayed if the account number was entered incorrectly or if the account has been closed. Contact your bank to confirm the account is active and can receive transfers.

If the return is still under review after three months, or if you see a message requesting documents you already submitted, contact your local tax office directly. You can find the office location and phone number on the National Tax Bureau website. Bring copies of your filed return and any supporting documents you submitted.

Frequently Asked Questions

Do I have to file a tax return in Taiwan to get a refund?

Yes. The refund is calculated only when you file. If you do not file, any overpaid withholding tax remains with the government. You must file a return during the May-to-June filing period to claim your refund.

Can I file a tax return in English?

The National Tax Bureau's online filing system has an English interface option. Paper forms are available in English at tax offices, but you may need to provide translations of supporting documents if they are not in Chinese or English.

What if I worked in Taiwan for only part of the year?

You still file a return for the full calendar year and report only the income you earned during the months you worked. Your refund is calculated based on your actual annual income, so partial-year workers often receive larger refunds because less tax was owed overall.

How long does a refund take if I file online versus by paper?

Online refunds typically arrive within one to three months. Paper returns take four to six weeks just to be processed, plus an additional one to two months for the refund to be issued, so online filing is significantly faster.

Can I receive my refund in a foreign bank account?

No. The National Tax Bureau only transfers refunds to Taiwanese bank accounts. If you do not have one, you must open a local account before filing your return.
