Your 2026 Compliance Checklist

Every form, threshold, and deadline a US expat in Taiwan needs to track this year. Bookmark this page and review it each January, and again as US-Taiwan tax treaty negotiations progress.

2026 tax checklist for US expats in Taiwan

1. Confirm Your Filing Requirement

File Form 1040 if worldwide gross income exceeds roughly $14,600 ($400 if self-employed), regardless of Taiwanese tax already paid.

2. Decide FEIE, FTC, or Both

Model your income against Taiwan's brackets, most moderate salaries do well on FEIE alone, higher earners should model adding the Foreign Tax Credit.

3. File FBAR If You Cross $10,000 (FinCEN Form 114)

Aggregate all Taiwanese bank and investment accounts. File by April 15 (automatic extension to October 15).

4. Check FATCA Reporting (Form 8938)

Applies at higher thresholds than FBAR, generally $200,000+ for single filers abroad ($400,000+ married filing jointly).

5. Confirm Self-Employment Tax Exposure

If you're a contractor or freelancer, budget for the full 15.3% self-employment tax since there's no Totalization Agreement to offset it.

6. Confirm Gold Card Tax Deduction Status (If Applicable)

If on a Gold Card, confirm your 50% deduction eligibility and years remaining, and model its effect on your Foreign Tax Credit.

Expert Guidance

When to Consult a Specialist

  • Multiple Items Overlap:Confirming which checklist items actually apply to your specific residency and income situation.
  • Property or Business Structuring:Reviewing reciprocity documentation and entity structures before committing to one.
  • State Domicile Questions:Determining whether you still owe a US state return while abroad.
  • National Taxation Bureau Classification:Confirming whether you've crossed the 183-day Taiwan residency threshold this year.
  • First Year Filing from Taiwan:Walking through the full checklist once with a specialist before going it alone in future years.

7. Monitor US-Taiwan Tax Treaty Developments

Check for updates on the pending tax agreement negotiations, a finalized treaty could change planning for higher earners.

8. Review State Domicile Status

Confirm whether your prior US state still considers you a resident for state tax purposes, particularly if you're from California, Virginia, New Mexico, or South Carolina.

9. Verify Any Property Ownership Structure

If you own property, confirm reciprocity eligibility documentation and size cap compliance, and track LVIT exposure on any future sale.

10. Confirm National Taxation Bureau Filing Status

Determine whether you meet the 183-day residency test, which affects whether progressive resident rates or flat 18% non-resident withholding applies.

11. Verify Beneficiary Designations on US Accounts

Confirm 401(k), IRA, and life insurance beneficiary designations are current. Cross-border estate planning gets materially more complex the longer you're abroad.

Annual Rhythm

A Quarter-by-Quarter View

Q1 (Jan–Mar)

Gather prior-year income records, Taiwanese bank statements, and passport stamps. Confirm your FEIE or FEIE/FTC combination for the prior US tax year.

Q2 (Apr–Jun)

File Form 1040 by the automatic June 15 expat deadline. File FBAR if the $10,000 threshold was crossed. Taiwanese income tax filing typically due in May.

Q3 (Jul–Sep)

If you filed an extension, this is your window before the October 15 deadline. Check on treaty negotiation updates.

Q4 (Oct–Dec)

Final extended deadline (Oct 15). Year-end is the last window for Roth conversions and reviewing Gold Card deduction timing before the tax year closes.

FAQ: 2026 Taiwan Expat Checklist

Do I need to redo this checklist every year?

Yes, thresholds are indexed annually and treaty negotiation status is genuinely worth monitoring given active recent movement.

What's the single most commonly missed item on this list?

Item 2, defaulting to the FEIE alone without checking whether the Foreign Tax Credit adds value given Taiwan's real progressive rates.
