American Expats in Taiwan

Updated on August 20, 2025.

Taiwan & U.S. Tax Timeline: Critical Dates for Dual Filers

Managing dual tax obligations between Taiwan and the United States requires careful attention to two distinct tax calendars. Understanding these timelines is crucial for maintaining compliance and avoiding penalties in both jurisdictions.

The Taiwan tax system operates on a pay-as-you-earn basis for employees, with employers withholding tax monthly at rates ranging from 5% to 40% depending on income levels. Self-employed individuals and those with significant non-employment income must make quarterly provisional tax payments based on the previous year's tax assessment. These provisional payments are due on January 31, April 30, July 31, and October 31, creating a continuous cycle of tax obligations that must be carefully managed alongside U.S. requirements.

Strategic Payment Planning to Avoid U.S. Penalties

The most critical aspect of dual tax compliance for U.S. expats in Taiwan is understanding that the June 15 automatic extension applies only to filing, not to payment obligations. This distinction has significant financial implications that require proactive planning to avoid unnecessary interest and penalties.

To effectively manage this payment timing challenge, expats should implement a multi-pronged approach. First, conduct a preliminary tax calculation by early March using your Taiwan income documentation and estimated U.S. tax obligations. This projection doesn't need to be perfect but should provide a reasonable estimate of your U.S. tax liability. Consider working with a tax professional familiar with both systems to ensure accuracy in this crucial calculation. As an expat CPA firm, we can help you with these items.

Second, establish a tax reserve account specifically for U.S. obligations. Since Taiwan taxes are paid through wage withholding and quarterly provisional payments throughout the year, you'll need separate liquidity for U.S. payments. Many expats find it helpful to set aside funds monthly, treating U.S. tax reserves as a fixed expense in their budget. This approach prevents the April 15 payment deadline from creating a cash flow crisis.

Third, leverage safe harbor provisions to minimize penalties. If you're unable to calculate your exact tax liability by April 15, you can avoid penalties by paying either 100% of your prior year's tax liability (110% if your prior year AGI exceeded $150,000) or 90% of the current year's tax. This safe harbor payment strategy provides protection while you finalize your actual tax calculations. As an expat CPA firm, we can help you with this.

For those with irregular income or significant Taiwan-source income, consider making quarterly estimated tax payments to the IRS. While Taiwan handles tax through wage withholding and provisional payments, the U.S. system may require quarterly payments if your withholding is insufficient. These payments are due April 15, June 15, September 15, and January 15, and help spread the tax burden throughout the year rather than facing a large payment in April.

Currency fluctuations between the New Taiwan Dollar (TWD) and U.S. dollar add another layer of complexity to payment planning. Since you'll likely earn income in TWD but owe taxes in dollars, exchange rate movements can significantly impact your tax liability. Consider using the yearly average exchange rate for income reporting (as permitted by the IRS) to smooth out volatility, and monitor exchange rates when planning your April payment to optimize the conversion timing. As an expat CPA firm, we can help you with these items.

Taiwan vs. U.S. Tax Systems: Direct Comparison

Understanding the fundamental differences between Taiwan and U.S. tax systems is essential for effective tax planning as an American expat. While both countries tax worldwide income for residents, their approaches to rates, deductions, and income classification vary significantly.

The Taiwan progressive tax system applies rates ranging from 5% on income above NT$560,000 (after deductions) to 40% on income exceeding NT$10,310,000. The basic personal exemption is NT$92,000 (2024), with additional standard deductions of NT$124,000 for singles or NT$248,000 for couples. This compares to U.S. federal rates ranging from 10% to 37%, though U.S. expats may benefit from the Foreign Earned Income Exclusion (FEIE) of $120,000 for 2023 and $126,500 for 2024.

One crucial difference lies in the treatment of investment income. Taiwan includes most capital gains in regular income, though certain securities transactions benefit from separate taxation or exemption. The U.S., conversely, distinguishes between short-term gains (taxed as ordinary income) and long-term gains (taxed at preferential rates of 0%, 15%, or 20% depending on income levels). This difference can significantly impact investment strategy for expats managing portfolios across both countries.

The Taiwan Tax System Explained in Detail

The Taiwan tax system presents unique complexities for American expats accustomed to U.S. tax principles. Taiwan's approach to income classification, taxation methods, and available deductions differs substantially from the American system, requiring careful study to optimize tax positions and ensure compliance.

Understanding U.S. Income Classifications

Before diving into the Taiwan system, it's essential to understand how the United States classifies and taxes different types of income, as this provides the framework for comparison and planning strategies.

The Taiwan Income Tax Categories

Taiwan categorizes income into ten distinct classifications, each with specific rules and tax treatment. This categorical approach differs fundamentally from the U.S. system and requires careful analysis to properly report income and claim applicable benefits.

1. Salary and Wage Income (薪資所得)

This category encompasses employment income including salaries, wages, bonuses, overtime pay, and allowances. Taiwan provides a special deduction for salary income of either NT$207,000 or 3% of salary income (whichever is lower) for 2024. Employers withhold tax monthly based on standard withholding tables, with rates from 5% to 40% depending on income levels and residency status.

2. Professional Practice Income (執行業務所得)

Professional practice income covers earnings from independent professional services including doctors, lawyers, accountants, engineers, and consultants. Unlike employees, professionals can deduct actual business expenses or use standard expense ratios set by the tax authority (typically 20-30% of gross receipts). This category requires maintaining proper books and records, with simplified options available for smaller practices.

Professionals must file provisional tax returns and make quarterly payments based on prior year income. The distinction between professional practice and business income depends on the nature of services, with intellectual and specialized services qualifying for this category's favorable treatment.

3. Business Income (營利所得)

Business income encompasses profits from commercial enterprises, including sole proprietorships and partnership distributions. Taiwan's profit-seeking enterprise income tax applies at 20% to corporate entities, with distributions to individuals facing additional taxation. Small businesses with monthly sales under NT$200,000 can opt for simplified taxation with deemed profit margins.

The business tax (VAT) system operates separately at 5% for most transactions, with input tax credits available for registered businesses. Export sales enjoy zero-rating, benefiting companies with international clients. Business income faces both entity-level and individual taxation, creating potential double taxation requiring careful planning.

4. Interest Income (利息所得)

Interest income includes earnings from bank deposits, bonds, and loans. Taiwan employs a 10% withholding tax on interest as a minimum tax, with amounts included in consolidated income for final calculation. An annual exemption of NT$270,000 applies to interest from financial institutions, significantly reducing tax burden for typical savings.

Foreign-source interest requires special attention. Interest from overseas accounts must be reported and included in Taiwan taxable income for residents. The lack of automatic information exchange with the U.S. doesn't eliminate reporting obligations, and voluntary compliance remains essential.

5. Dividend Income (股利所得)

Dividend taxation underwent significant reform, offering taxpayers two calculation methods. Option A allows a 28% flat tax on dividend income, separated from other income. Option B includes dividends in consolidated income with an 8.5% tax credit (capped at NT$80,000). Most expats benefit from Option B unless dividend income is substantial.

Foreign dividends face full Taiwan taxation without the domestic dividend tax credit. This creates disadvantages for U.S. investment portfolios, requiring careful consideration of investment location and structure. Taiwan-listed foreign ETFs may provide more favorable treatment than direct foreign holdings.

6. Rental Income (租賃所得)

Rental income from Taiwan property faces progressive taxation with significant deduction opportunities. Landlords can deduct actual expenses with documentation or claim a 43% standard deduction without receipts. This generous standard deduction makes residential rentals particularly tax-efficient for smaller landlords.

Special rules apply to short-term rentals and Airbnb operations. Properties rented for less than one month continuously may face business tax requirements. Foreign property rentals by Taiwan residents require reporting, though enforcement mechanisms remain limited without information exchange agreements.

7. Royalty Income (權利金所得)

Royalty income includes payments for intellectual property use including patents, trademarks, copyrights, and technical know-how. Taiwan applies 10% withholding on domestic royalties, with amounts included in consolidated income. International royalty flows face treaty considerations, though Taiwan's limited treaty network affects planning options.

8. Capital Gains (財產交易所得)

Capital gains treatment varies significantly by asset type. Securities transactions on Taiwan exchanges generally escape income tax, facing only securities transaction tax (0.3% on sales). However, unlisted securities and foreign investments face regular income tax on gains. Real estate gains trigger specific taxes including the house and land gains tax for properties held less than two years.

The Alternative Minimum Tax (AMT) at 20% captures certain exempt income including overseas gains exceeding NT$6.7 million. This backstop prevents excessive tax avoidance while maintaining competitiveness for typical investment portfolios.

9. Prize and Lottery Income (競技競賽及機會中獎獎金)

Prize winnings and lottery income face 10% withholding on amounts exceeding NT$5,000, with higher rates (20%) for prizes above NT$20,000. These amounts generally aren't included in consolidated income, making the withholding final. Foreign gambling winnings require reporting if remitted to Taiwan.

10. Other Income (其他所得)

This residual category captures miscellaneous income including retirement payments, alimony, one-time payments, and income not classified elsewhere. Tax treatment varies based on specific income nature, with some items qualifying for exemptions or reduced rates. Careful classification ensures optimal treatment within Taiwan's categorical system.

Taiwan Taxes and Foreign Tax Credit Eligibility

Understanding which Taiwan taxes can be claimed as a credit on Form 1116 is crucial for reducing your U.S. tax liability. While most income taxes are creditable, social insurance contributions and certain other taxes are not.

eTax System and Tax Assessment Notice: Understanding Taiwan's Digital Tax System

For American expats, navigating Taiwan's tax system means becoming familiar with two key concepts: the eTax Portal and the Tax Assessment Notice. These are central to the process of filing your Taiwan tax return and receiving your final tax assessment.

What is the eTax Portal?

eTax Portal (財政部電子申報繳稅服務網) is Taiwan's official online system for filing tax returns. It's the digital backbone of the Taiwan tax administration, allowing individuals and tax agents to submit their tax declarations electronically. Think of it as Taiwan's equivalent of the IRS's e-file system, but with additional features. To use it, you can authenticate using your Alien Resident Certificate (ARC) number combined with a password, National Health Insurance card with a card reader, or digital certificate.

What is a Tax Assessment Notice?

The Tax Assessment Notice (綜合所得稅核定通知書) is your official tax assessment from the Taiwan National Taxation Bureau. After you submit your tax return, the tax authority processes your information and sends you this document. It's the final word on your Taiwan tax liability for the year. The Tax Assessment Notice will clearly state:

• Your total calculated income tax.
• Your supplementary premium (if applicable).
• The amount of tax already paid through withholding or provisional payments.
• Whether you owe additional tax or are entitled to a refund.

The Tax Assessment Notice is a critical document for U.S. tax purposes, as it provides the official amount of Taiwan tax you paid that can be used to claim the Foreign Tax Credit on your U.S. Form 1040.

U.S.-Taiwan Social Security Considerations

Unlike many countries, the U.S. and Taiwan do not have a Social Security Totalization Agreement due to the unique diplomatic status between the two territories. This absence creates potential double social insurance obligations that require careful planning and understanding.

For employees and self-employed individuals, this means potentially being subject to both U.S. Social Security (FICA) and Taiwan's social insurance systems simultaneously. U.S. citizens working for U.S. employers in Taiwan remain subject to FICA taxes, while also being required to participate in Taiwan's Labor Insurance and National Health Insurance systems. Self-employed individuals face even more complexity, potentially owing U.S. self-employment tax while also contributing to Taiwan's occupational pension system.

The lack of totalization means workers cannot combine credits from both countries to qualify for benefits. Years worked in Taiwan don't count toward U.S. Social Security eligibility, and vice versa. This can particularly impact those with split careers between the two countries who may not accumulate sufficient credits in either system for full benefits.

Taiwan Social Security and Pension System

Three-Pillar System Overview

Taiwan's pension system is divided into three pillars:

• Pillar I - Labor Insurance Old-Age Benefits: This is the mandatory social insurance system providing lump-sum or annuity payments upon retirement. Contribution rates total approximately 11.5% of insured salary, split among employer (70%), employee (20%), and government (10%).
• Pillar II - Labor Pension (New System): Mandatory defined contribution system where employers contribute at least 6% of monthly wages to individual accounts. Employees may voluntarily contribute up to 6% additional with tax benefits.
• Pillar III - Private Savings: Individual retirement savings through commercial insurance products, mutual funds, or bank deposits. Limited tax incentives compared to U.S. qualified plans.

Taiwan Retirement Accounts and U.S. Tax Treatment

The U.S. tax treatment of Taiwan retirement accounts is complex and varies significantly by the type of account. The IRS does not consider most Taiwan plans to be "qualified" in the same way as a 401(k) or IRA, leading to potential reporting and taxation challenges.

PFIC Mitigation Strategies for Taiwan Retirement Accounts

A Passive Foreign Investment Company (PFIC) is a foreign corporation that meets specific income or asset tests. Many Taiwan mutual funds and unit-linked insurance products fall into this category, leading to complex and often punitive U.S. tax consequences. Navigating PFICs is one of the most significant challenges for U.S. expats with Taiwan retirement accounts.

Identifying PFICs in Taiwan Retirement Plans

• Request investment allocation details from your plan administrator.
• Look for terms indicating collective investment schemes or mutual funds.
• Taiwan-listed ETFs are typically PFICs.
• Investment-linked insurance products almost always contain PFICs.

Compliance Options

Since a Qualified Electing Fund (QEF) election is rarely possible due to lack of required documentation, the most common strategies are:

• Mark-to-Market Election: This is often the most practical choice. It requires you to calculate and report the annual gain or loss on your PFIC investments based on their fair market value.
• Default Excess Distribution Regime: This is the most punitive method, leading to deferred tax with interest charges on distributions.

Documentation Requirements

To comply with PFIC rules, you must maintain detailed records:

• Annual statements showing year-end values.
• Records of all contributions, distributions, and transfers.
• A breakdown of the underlying fund investments.

Taiwan Financial Account Reporting Requirements

U.S. tax law requires you to report your foreign financial accounts to the IRS if their aggregate value exceeds certain thresholds. This includes FBAR and FATCA reporting.

FBAR and FATCA Reporting

Accounts that must be reported include:

• Bank Accounts: Checking accounts, savings accounts, time deposits, foreign currency accounts.
• Investment Accounts: Securities accounts at Taiwan brokers or banks.
• Retirement Accounts: Labor Pension accounts, private pension schemes.
• Insurance Products: Policies with cash surrender value, investment-linked insurance.
• Business Accounts: If you have signature authority or an ownership interest exceeding 50%.

Form 8938 Thresholds for U.S. Expats

These are the reporting thresholds for U.S. citizens living abroad. Note that lower thresholds apply if you reside in the U.S.

• Single/Married Filing Separately: $200,000 on the last day of the year or $300,000 at any point during the year.
• Married Filing Jointly: $400,000 on the last day of the year or $600,000 at any point during the year.

Taiwan Government Benefits and Their U.S. Tax Treatment

Certain Taiwan government benefits are not considered taxable income for U.S. tax purposes. Here's a brief overview:

• Childbirth Subsidy: One-time payments for childbirth are not considered taxable income and do not need to be reported on your Form 1040.
• Childcare Allowance: Monthly childcare subsidies are generally not reportable as they're considered social welfare benefits.
• Unemployment Benefits: Employment Insurance benefits must be reported as income for U.S. tax purposes.
• Low-Income Subsidies: Government assistance for low-income families is typically not treated as taxable income.

Taiwan Business Structures and U.S. Reporting

For self-employed individuals and business owners, the U.S. reporting requirements vary based on the Taiwan business structure. Incorrect classification can lead to significant penalties.

Important Considerations

• No Tax Treaty: The absence of a U.S.-Taiwan tax treaty means no treaty benefits are available.
• Documentation: Maintain detailed records in both Chinese and English.
• Tax Year: The Taiwan tax year is the calendar year, which aligns with the U.S. tax year, simplifying reporting.
• Exit Considerations: Be aware of potential Taiwan tax obligations when leaving, including final tax clearance requirements.

Taiwan Visa Options and Their Tax Implications

Taiwan offers various visa categories for American citizens, each with distinct requirements, benefits, and tax implications. Understanding these options is crucial for optimizing your tax position while ensuring legal residence status.

Taiwan Employment Gold Card

The Taiwan Employment Gold Card represents Taiwan's premier visa for highly qualified professionals, combining work permit, residence visa, re-entry permit, and Alien Resident Certificate in one document. Requirements include meeting salary thresholds (typically NT$160,000+ monthly), specialized expertise in designated fields, or significant professional achievements. The Gold Card provides open work rights without employer sponsorship and immediate family reunification benefits.

Tax implications favor Gold Card holders through potential qualification for special foreign talent tax rates. Qualifying individuals can opt for a flat 18% tax rate on salary income exceeding NT$3 million, providing significant savings versus standard progressive rates. The three-year validity with renewal options provides long-term tax planning certainty. Family members receive dependent ARCs with work rights after one year, enabling dual-income optimization strategies.

Regular Work Permit and ARC

Standard employment authorization requires employer sponsorship with minimum salary requirements varying by industry (typically NT$47,971 monthly). The work permit ties to specific employer, requiring new applications for job changes. Residence visa converts to ARC upon arrival, with annual renewals tied to employment continuation.

Workers face standard progressive taxation on employment income from day one. Employers handle monthly tax withholding and annual tax filing assistance. The tied nature of the visa limits job mobility and salary negotiation leverage. Permanent residence eligibility after five continuous years provides eventual stability.

Entrepreneur and Investment Visa

Taiwan's entrepreneur visa targets business founders and investors. Requirements include minimum capital investment (varies by business type), detailed business plan with local economic benefit, and often recommendation from government startup programs. The visa permits business operation with potential to employ others.

Entrepreneurs face corporate income tax at 20% on business profits. Individual salary from own company faces standard progressive rates. Business expense deductions and startup incentives may apply. The Investment Immigration program for NT$10 million+ investments provides expedited permanent residence pathway. Various tax incentives exist for businesses in promoted industries or science parks.

Student and Graduate Retention

Student visas offer pathways to Taiwan residence with post-graduation work opportunities. Requirements include university admission, financial proof of support, and health examination. Graduates from Taiwan universities can apply for six-month extension for job seeking, converting to work permit upon employment.

Students can work up to 20 hours weekly with work permit. Income faces standard tax rates with basic exemptions often eliminating tax burden. Post-graduation employment transitions to full taxation. Education expenses are generally not deductible for Taiwan tax purposes. The pathway from student to permanent resident requires continuous legal residence.

APRC (Permanent Residence)

The Alien Permanent Resident Certificate (APRC), formerly called "Plum Blossom Card," provides indefinite residence rights. Requirements include five years continuous legal residence, 183+ days presence annually, financial stability proof, and clean criminal record. Special categories exist for investors and professionals with reduced requirements.

APRC holders enjoy complete work freedom without permits. Tax treatment remains identical to other foreign residents. The permanent status simplifies long-term financial planning. Unlike temporary visas, no employer sponsorship required for maintenance. Re-entry permits allow extended absence without losing status.

Taiwan's Special Professional Visa and Digital Nomad Options

Taiwan has introduced various programs to attract skilled professionals and accommodate modern remote work arrangements. These programs address contemporary work patterns while maintaining Taiwan's structured approach to immigration.

Special Foreign Professional Programs

Taiwan designates certain fields as priority for foreign talent recruitment including technology, economy, education, culture, arts, sports, and specialized fields. Special professionals enjoy streamlined visa processes and extended validity periods. Benefits include facilitated permanent residence applications and potential tax incentives.

The program provides work flexibility across multiple employers within designated field. Family members receive more favorable treatment for work rights. Tax planning opportunities through special foreign talent rates may apply. Integration with Gold Card program provides premium pathway for qualified individuals.

Digital Nomad and Remote Work Considerations

While Taiwan lacks a dedicated digital nomad visa, several options accommodate remote workers. The Gold Card allows location-independent work without employer tie. Visitor visas permit up to 90 days stay (extendable to 180 days) though work authorization remains restricted. Business visitor provisions may cover certain professional activities.

Digital workers spending over 183 days in Taiwan become tax residents on worldwide income. Income from foreign clients/employers remains taxable in Taiwan for residents. Without tax treaty protection, careful structuring is essential to avoid double taxation. Consider maintaining non-Taiwan contracts to preserve foreign-source characterization.

Practical Considerations for Remote Workers

Banking access improves significantly with ARC versus visitor status. However, some Taiwan banks restrict services for U.S. citizens due to FATCA requirements. International banks like Citibank or HSBC often provide more accessible options. Account opening triggers reporting obligations requiring careful FBAR and Form 8938 compliance.

Social insurance obligations arise even for remote workers if Taiwan tax residence is established. This includes National Health Insurance (approximately 5.17% of income) and potentially Labor Insurance. Self-employed individuals bear both employee and employer portions of social insurance. The excellent healthcare system provides value despite additional cost burden.

Frequently Asked Questions for U.S. Expats in Taiwan

Q: How do I avoid double taxation without a U.S.-Taiwan tax treaty?

Without a formal tax treaty, avoiding double taxation requires strategic use of the Foreign Tax Credit (FTC) and Foreign Earned Income Exclusion (FEIE). The FTC allows you to credit Taiwan income taxes against U.S. tax liability on the same income. For most expats in Taiwan's relatively high-tax environment, FTC provides better results than FEIE. You can claim FTC using Form 1116, categorizing income as general or passive. Taiwan taxes paid typically exceed U.S. taxes on the same income, generating excess credits that carry forward 10 years. Careful timing of income recognition and tax payments optimizes credit utilization.

Q: Can I contribute to both Taiwan and U.S. retirement accounts?

Yes, with careful planning. Taiwan Labor Pension contributions (employer's 6% mandatory) don't prevent U.S. retirement contributions. For U.S. accounts (IRA, 401(k)), you need earned income not excluded by FEIE to contribute. If using FTC instead of FEIE, all foreign earned income remains eligible for retirement contribution calculations. Taiwan voluntary pension contributions face unfavorable U.S. tax treatment as non-qualified foreign trusts. Consider maintaining U.S. retirement accounts for tax-advantaged growth while viewing Taiwan's mandatory systems as social insurance rather than retirement savings.

Q: What happens to my U.S. state tax obligations when I move to Taiwan?

State tax obligations depend on your former state and steps taken to establish non-residence. States like California, New York, Virginia, and South Carolina aggressively pursue former residents. Key steps include obtaining Taiwan ARC and registering local address, canceling state driver's license and voter registration, closing state bank accounts, selling or renting out state property, and filing final part-year or non-resident state returns. Some states continue taxing certain income regardless of residence. States with no income tax (Texas, Florida, Washington) simplify expatriation. Document your Taiwan residence thoroughly to defend against state claims.

Q: How are Taiwan real estate investments taxed for U.S. expats?

Taiwan real estate faces multiple tax considerations. Rental income is taxed progressively with either 43% standard deduction or actual expenses. Property sales within two years trigger house and land gains tax at rates up to 45%. After two years, rates decrease significantly. Annual house tax and land value tax apply based on government assessments. For U.S. purposes, report rental income on Schedule E with depreciation over 27.5 years. Capital gains face U.S. tax regardless of Taiwan holding period, with primary residence exclusion potentially available. Foreign tax credits apply for Taiwan taxes paid. Consider timing sales for optimal treatment under both systems.

Q: Should I choose the Foreign Earned Income Exclusion or Foreign Tax Credit?

For Taiwan's moderate-to-high tax environment, the Foreign Tax Credit (FTC) typically provides better results than the Foreign Earned Income Exclusion (FEIE). Taiwan taxes at rates comparable to or exceeding U.S. rates, generating excess credits for future use. FTC preserves eligibility for U.S. retirement contributions and doesn't require meeting physical presence or bona fide residence tests. However, FEIE might benefit those with income just under $126,500 who can eliminate U.S. tax entirely. Many expats combine strategies, using FEIE for earned income and FTC for investment income. Once you revoke FEIE, you cannot re-elect for five years without IRS permission.

Q: How do I handle Taiwan taxation of my U.S. investment accounts?

Taiwan taxes worldwide investment income for residents at progressive rates up to 40%, with Alternative Minimum Tax of 20% on certain income. U.S. investment accounts face Taiwan taxation on interest, dividends, and realized gains. Foreign investment income over NT$6.7 million may trigger AMT. Taiwan provides no exemption for foreign investment income. Report U.S. account income on Taiwan tax returns, converting amounts to TWD. The U.S. provides foreign tax credits for Taiwan investment taxes paid. Consider holding tax-efficient investments (index funds vs. active funds) to minimize taxable distributions.

Q: What are the implications of maintaining U.S. LLCs or corporations while living in Taiwan?

U.S. business entities face complex Taiwan tax treatment. Single-member LLCs, disregarded for U.S. purposes, may be treated as corporations in Taiwan, creating double taxation risk. Multi-member LLCs might be classified as partnerships or corporations based on characteristics. C-corporations face double taxation with Taiwan tax on distributions plus U.S. corporate tax. S-corporations lose pass-through benefits for Taiwan tax purposes. Taiwan's controlled foreign company (CFC) rules may apply if passive income exceeds certain thresholds. Management from Taiwan could create Taiwan tax residence for the entity, triggering 20% corporate tax. Consider restructuring before relocating or establishing Taiwan entities for local operations.

Q: How does Taiwan tax U.S. Social Security benefits?

Without a totalization agreement or tax treaty, U.S. Social Security benefits received by U.S. citizens in Taiwan face taxation by both countries. The U.S. taxes Social Security benefits based on total worldwide income, with up to 85% potentially taxable. Taiwan includes Social Security benefits in taxable income for residents, applying progressive rates. This creates true double taxation without treaty relief. Planning strategies include timing residency changes to minimize overlap, maintaining some U.S.-source income to utilize foreign tax credits, and considering whether to begin benefits before or after establishing Taiwan residence. The lack of treaty protection makes Social Security planning particularly important for Taiwan expats.

Q: Can I use Taiwan's healthcare system, and how does it affect my taxes?

Taiwan residents must enroll in National Health Insurance (NHI) after residing six months (immediate for employees). NHI costs approximately 5.17% of monthly income (split between employer, employee, and government) with monthly cap around NT$35,000. Premiums are not creditable against U.S. taxes but may be deductible as foreign taxes paid. Coverage is comprehensive with minimal copayments. U.S. expats satisfy ACA requirements through Taiwan coverage. Some maintain international insurance for U.S. visits or treatments not covered by NHI. Taiwan health insurance premiums are deductible for Taiwan tax purposes up to NT$24,000 per person annually.

Q: What triggers Taiwan tax audits, and how should I prepare?

Taiwan tax authorities employ risk-based audit selection. Common triggers include discrepancies between reported income and information from employers/banks, excessive deduction claims versus income level, foreign income reporting inconsistencies, late or amended returns, and unusual changes in reported income. U.S. expats face heightened scrutiny due to complex international finances. Preparation strategies include maintaining documentation in Chinese with English translations, working with local tax agents familiar with expat issues, keeping proof of foreign taxes paid, documenting exchange rates used, and responding promptly to tax bureau notices (typically 10-day deadlines). Audits may review up to five years, or seven years for suspected evasion.
