Why US-Vietnam Tax Work Creates EA Demand
Last reviewed: July 20, 2026. This article reflects current IRS rules and EA exam requirements as of this date.
The first thing you learn about US-Vietnam tax work is that there's no treaty. The second thing you learn is that there are Americans everywhere.
Hanoi has international schools full of American teachers. Ho Chi Minh City has tech companies, manufacturing operations, and a startup scene that attracts American founders and engineers. Da Nang has become a digital nomad hub, with coworking spaces and expat communities that rival Chiang Mai. Nha Trang and Phu Quoc have American retirees.
Estimates put the American population in Vietnam somewhere between 20,000 and 50,000. Every single one of them has US filing obligations. Many also have Vietnamese filing obligations. The two systems do not coordinate.
That gap between obligation and help is a career opportunity for Enrolled Agents who understand cross-border tax.
The complexity stack is real
Americans in Vietnam face layers of tax complexity that increase with income, assets, and time in country.
A junior English teacher on a one-year contract at an international school in District 2 might have a straightforward return. FEIE. One W-2 equivalent from a Vietnamese employer. One Vietnamese bank account below the FBAR threshold. Maybe a US brokerage account. This is a one-hour return for someone who knows what they're doing.
A tech founder who moved from San Francisco to Ho Chi Minh City three years ago and set up a Vietnamese limited liability company is a different story. They have ownership in a foreign corporation. potentially a Controlled Foreign Corporation requiring Form 5471. GILTI (Global Intangible Low-Taxed Income) rules may apply. Their US brokerage account holds ETFs. Their Vietnamese investment portfolio includes funds that are almost certainly PFICs under US rules. They have three Vietnamese bank accounts, two in VND and one in USD. They're paying Vietnamese personal income tax at the 35% marginal rate and trying to figure out whether FTC or FEIE produces a better result this year.
This return might take 15 hours. It requires entity classification analysis, PFIC reporting on Form 8621, GILTI calculations, FBAR filings, and a cross-border tax equalization calculation. It is not a software product return. It is a professional services return.
The gap between the teacher and the founder is the market. Most Americans in Vietnam land somewhere in the middle. They have enough complexity that a software product won't handle it, and not quite enough that they're on a Big Four firm's radar. That middle is where an EA practice lives.
Who is doing this work right now
Not many people.
A handful of US expat tax firms have Vietnam pages on their websites. Greenback Expat Tax Services covers Vietnam. Taxes for Expats has a Vietnam guide. A few solo practitioners in the region handle cross-border returns for Americans in Southeast Asia.
The supply is thin. Many preparers who advertise expat expertise have never filed a return involving Vietnamese-sourced income. They don't know that Vietnam taxes non-residents at a flat 20% rate. They don't know that the Vietnamese tax year follows the calendar year. They've never looked at a Vietnamese tax payment receipt and tried to figure out which line on Form 1116 it maps to.
An EA who builds actual Vietnam competence. who understands the Vietnamese PIT system, who knows how to read a Vietnamese employment contract for US tax implications, who has filed streamlined compliance cases for clients who went years without filing. can command a premium and build a practice that competitors can't easily replicate.
The treaty horizon changes the math
Treasury named Vietnam as a treaty negotiation target in 2026. No one knows when a treaty will materialize. Treaty negotiations take years. But the direction is clear.
When a treaty arrives, the Vietnam tax market changes. US citizens in Vietnam will need preparers who understand what the treaty changes. and what it doesn't. Pre-treaty returns don't disappear. Clients who filed under the old rules will need amended returns, treaty-based return positions on Form 8833, and advice on whether to change their prior-year elections.
An EA who builds Vietnam expertise now is positioned to be the person clients call when the treaty drops. The competitor who shows up after the treaty is announced will be playing catch-up with a market that already has trusted preparers.
The EA is the right credential for this
The EA exam covers exactly what this market needs. Part 1 covers individual taxation. FEIE, FTC, filing status for expats, foreign housing exclusion. Part 2 covers business entities. the entity classification analysis you need for that Vietnamese LLC, basis calculations for cross-border business assets. Part 3 covers representation, ethics, and procedures. what happens when the IRS audits a Vietnam-based client, how to handle a streamlined compliance submission, how Circular 230 governs your practice.
Three exams. Federal credential. No degree required. Total direct costs under $800.
Vietnam cross-border tax work is not the easiest niche. It's the niche where the supply of competent preparers is lowest and the demand is real and growing. If you want to build a practice serving Americans in one of the most dynamic economies in Southeast Asia, the EA credential is how you start.
