Why the FEIE Fits Most Expats Here
Vietnam's top resident tax bracket (35%) applies at a lower absolute threshold than in the Philippines, but most teaching, remote-work, and mid-level corporate salaries in Vietnam still sit comfortably under the FEIE's $132,900 cap for 2026. The exclusion typically shields the entire salary of a working American here without needing to model the Foreign Tax Credit as a first resort.
Qualifying for the FEIE: Two Tests
Physical Presence Test: 330 full days outside the US in any 12-month period. Straightforward to track, though frequent visa-run travel (common before the 2026 overstay crackdown, less advisable now) complicates day counting.
Bona Fide Residence Test: An uninterrupted full tax year of Vietnamese residency. More achievable for those on a proper TRC and work permit than for tourist-visa remote workers cycling in and out every 90 days.
The First-Year Timing Trap: Form 2350
Arriving mid-year means you likely won't satisfy either FEIE test by the normal April 15 deadline. Form 2350 requests an extension specifically to wait until you qualify, avoiding a forced early filing that locks you into a worse outcome for that year.
Visa Stability Affects Your Qualifying Test More Than the Amount
Unlike most countries in our coverage, the practical challenge in Vietnam is less about the FEIE cap and more about visa stability supporting the Bona Fide Residence Test. Someone genuinely working remotely on a rolling tourist e-visa, rather than a proper work permit, faces both an immigration risk and a weaker case for Bona Fide Residence, the Physical Presence Test becomes the safer fallback in that scenario.
When the FEIE Isn't Enough
Senior corporate transferees and business owners earning well above the cap should model the Foreign Tax Credit against actual Vietnamese PIT paid (up to 35% for residents) as a supplement for income above the exclusion.
Worked Example: An ESL Teacher on a Work Permit
An American ESL teacher in Da Nang earns $42,000 on a proper work permit and TRC. Comfortably under the FEIE cap, her full salary is shielded from US tax once she satisfies the Bona Fide Residence Test after her first full tax year in Vietnam. Her stable TRC status, unlike a rolling tourist visa, gives her a clean, defensible Bona Fide Residence claim.
