Taiwan Inheritance Tax: Rates, Exemptions, and Filing Deadlines for Foreign Heirs

Taiwan's estate tax catches many foreign families off guard. The National Taxation Bureau requires a comprehensive estate tax return within six months of death — and without the clearance certificate it produces, banks won't release frozen deposits and land offices won't transfer property titles. Missing this window triggers interest-bearing penalties that compound fast.

Here's what foreign heirs actually need to know about Taiwan's inheritance tax system.

Who Owes Taiwan Estate Tax

Tax jurisdiction depends on the deceased's residency status at the time of death:

• Taiwan domiciliaries (active household registration or 183+ days of residence per year): their worldwide assets are taxable in Taiwan.
• Non-domiciliaries and foreign nationals: only Taiwan-sited assets — local bank deposits, real estate, securities, and physical property located in Taiwan — are subject to estate tax.

This distinction matters enormously. A British expat who maintained household registration in Taipei has their UK pension and London flat pulled into the Taiwan tax base. A US citizen who never registered a household owes tax only on Taiwanese assets.

2025/2026 Estate Tax Brackets

Taiwan uses three progressive brackets:

The formula: (Net Taxable Estate × Rate) − Progressive Difference = Tax Owed

For context, NT$56.21 million is roughly US$1.8 million. Most single-property estates in Taiwan fall within the 10% bracket.

Exemptions and Deductions

The net taxable estate is calculated by subtracting exemptions and deductions from gross estate value:

• Basic exemption: NT$13,330,000 (roughly US$430,000)
• Surviving spouse deduction: NT$5,530,000
• Each lineal descendant: NT$560,000 (plus an additional NT$560,000 for each year under age 20)
• Each surviving parent: NT$1,380,000
• Disabled heir: NT$6,930,000
• Standard funeral expense: NT$1,380,000 (flat deduction — no receipts needed)
• Daily necessities: NT$1,000,000
• Professional equipment: NT$560,000

Critical limitation: Non-ROC citizens and non-domiciliaries qualify only for the basic NT$13.33 million exemption. The spouse, descendant, and parent deductions are unavailable to them.

The Estate Tax Clearance Certificate

This certificate is the master key to the entire estate. No bank, stock brokerage, or land office will release or transfer assets without it.

The filing process:

1. Determine the filing office. ROC citizens file at the tax bureau where the deceased's household registration was located. Non-residents and foreign nationals file with the National Taxation Bureau of Taipei directly.
2. File within six months of death. If international document collection requires more time, submit a written extension request before the deadline — the bureau can grant up to three additional months.
3. Pay assessed tax and receive clearance. Once the NTB reviews the return and taxes are paid, they issue the clearance certificate (or exemption certificate if the estate falls below thresholds).

What Happens If You Miss the Deadline

Late filing triggers automatic penalties: interest accrues on the tax owed from the day after the six-month deadline, and the NTB assesses additional administrative fines. The compounding effect is significant — a three-month delay on a NT$5 million tax liability can add hundreds of thousands of NT$ in penalties.

For foreign heirs managing document authentication through TECO offices overseas, the six-month deadline approaches fast. Start the tax return preparation the moment the household deregistration transcript is in hand.
