FEIE Qualification in Thailand
Physical Presence Test
Thailand's visa rules often require border runs or visa renewals that may take you to neighboring countries. Days in Cambodia, Laos, or Malaysia still count as days outside the US for the 330-day test. Keep thorough records of all border crossings.
Bona Fide Residence Test
A Thai work permit, Non-Immigrant Visa (O, B, or ED), or Thailand Elite Visa support bona fide residence. Thai tax registration and a Thai Tax ID (TIN) provide additional evidence. Retirement visa holders should document local ties.
Common Visa Types:
Thailand Tax System

Tax Rates
Progressive rates from 0% (up to 150,000 THB) to 35% (above 5 million THB). Since January 2024, foreign income remitted to Thailand in the same year earned is taxable.

Banking & FBAR in Thailand
Major Banks (THB)
FBAR Reminder
All Thai bank accounts must be reported on FBAR if aggregate foreign balances exceed $10,000. This includes both Thai baht and foreign currency accounts. Thai fixed deposit accounts and investment accounts at Thai brokerages are also reportable.
FATCA Compliance
Thailand signed a Model 1 IGA with the US in 2016. Thai banks are increasingly requiring US citizens to provide W-9 forms and SSN/TIN. Some smaller Thai banks may be less aware of FATCA requirements, but major banks comply.

FAQ: US Taxes in Thailand
How did Thailand's 2024 tax change affect US expats?
Before 2024, Thailand used a territorial system where only Thai-source income was taxed. Starting January 2024, foreign income remitted to Thailand in the same calendar year it was earned is now taxable. This means US expats transferring income to Thai bank accounts may now owe Thai tax on that income, creating new Foreign Tax Credit opportunities but also new compliance obligations.
Can I use the FEIE while living in Thailand?
Yes. Thailand is a popular destination for FEIE qualification. The low cost of living means many expats' income falls below the FEIE exclusion amount ($130,000 for 2025). Both the Physical Presence Test and Bona Fide Residence Test can work, though the lack of a permanent visa option for many expats makes the physical presence test more common.
Is there a totalization agreement between the US and Thailand?
No. There is no totalization agreement between the US and Thailand. This means if you work in Thailand and contribute to Thailand's social security system, you may also owe US self-employment tax or Social Security tax, resulting in potential double taxation on social insurance contributions.
Do I report Thai bank accounts on FBAR?
Yes. All Thai bank accounts count toward the $10,000 aggregate threshold for FBAR filing (FinCEN 114). This includes savings accounts, fixed deposits, and any financial accounts at Thai institutions. The deadline is April 15 with automatic extension to October 15.
How does the Thailand Elite Visa affect my tax situation?
The Thailand Elite Visa (now Thailand Privilege) grants long-term residence but does not automatically make you a Thai tax resident. You become a Thai tax resident by spending 180+ days in Thailand in a calendar year. The visa itself supports a bona fide residence FEIE claim if you establish genuine ties to Thailand.
