Filing a US return from another country is not like filing one from Ohio. You’re dealing with foreign bank account reporting, foreign tax credits and sometimes a foreign corporation that the IRS wants to hear about every single year. Picking the wrong preparer can mean missed exclusions, wasted money, or an amended return down the road.
The six services below all work with US citizens living outside the country, but they’re built for different situations. Some are software-first and built for volume. Others are boutique CPA shops that specialize in the harder corners of the tax code. Here’s how they stack up.
Best for Complex Foreign Business Filings – Universal Tax Professionals
Universal Tax Professionals is a specialist firm built around US expat taxes, with flat rate pricing and what it describes as fast returns and personalized attention. The firm is led by Josh Katz, CPA, who has spent 16 years focused exclusively on expat and international tax, which is a narrower lane than most general preparers ever work in.
That narrow focus shows up most clearly around foreign corporations. Most preparers rarely see a Form 5471 in a given year, but this team prepares them routinely, which matters if you own a foreign corporation and need accurate Subpart F and GILTI reporting alongside it. Getting those filings wrong, or skipping them, is not a small clerical issue.
The firm also reviews and corrects prior-year mistakes before the IRS catches them, which matters because penalties on a missed Form 5471 start at $10,000 per form, per year. For an American who owns a business overseas, or who inherited a messy filing history after years of DIY software, that kind of cleanup work is the difference between a manageable fix and a growing liability.
Someone with a simple W-2 and a straightforward foreign tax credit probably doesn’t need this level of specialization. But for owners of foreign corporations, or anyone who suspects a past filing was done wrong, it’s the kind of depth that’s hard to find elsewhere.
Best for Software-Driven Simplicity – MyExpatTaxes
MyExpatTaxes is built as software first, not a traditional CPA engagement. The company was awarded Best Expat Tax Software Service by The Balance and sells itself on affordable packages used by thousands of US expats every year.
That software-driven model is a good fit for expats with relatively straightforward returns who want to self-file with guidance rather than hand everything to a preparer. The tradeoff is that a software platform, even a strong one, is a different experience than working directly with a CPA on a complicated foreign business or investment structure. If your filing involves a foreign corporation, trust, or multiple income streams across countries, this is less suited to that depth than a dedicated firm would be.
Best for CPA and Enrolled Agent Access – Greenback Expat Tax Services
Greenback Expat Tax Services pairs expats with CPAs and IRS Enrolled Agents rather than a general tax preparation pipeline. The company positions itself around hassle-free service for expats who want the filing handled without managing the process themselves.
Working with credentialed CPAs and Enrolled Agents is a real advantage if you want a licensed professional attached to your return, particularly for anyone who has had a bad experience with a non-specialist preparer in the past.
Best for Long-Tenured Expat Tax Experience – Taxes for Expats
Taxes for Expats has been doing CPA-led expatriate tax preparation for 25+ years, which is a longer track record than most firms in this space can point to. The firm markets itself as a trusted choice for American expat tax services broadly.
That tenure is reassuring if you value a firm that has been through multiple rounds of tax law changes affecting expats, from FATCA to changing foreign tax credit rules. It’s a generalist expat practice rather than one built around a specific niche like foreign business ownership, so the depth you get on a highly specific situation may vary compared to a firm built around that exact problem.
Best for In-Person or DIY Flexibility – H&R Block
H&R Block is the most recognizable name on this list, and it covers far more than expat returns. The company offers do-it-yourself online filing starting at $0, DIY with Tax Pro Review starting at $75 and full-service tax prep starting at $99, with options to file online, with a dedicated tax pro, or in person.
That range of formats is genuinely useful if you want to choose how much human help you pay for, and the MyBlock account keeps your documents and refund status in one place. H&R Block also offers a free Second Look review of your past 3 years of returns, which can catch errors before they become a problem, similar in spirit to how experts suggest building a recession-proof emergency fund before you need it rather than after. The tradeoff is that H&R Block serves the entire US tax-filing population, not just expats, so the expat-specific expertise may not run as deep as a firm that works exclusively with Americans abroad.
Best for Overseas Benefit Optimization – Expat Tax Online
Expat Tax Online focuses on helping Americans abroad maximize tax benefits overseas, pairing expert assistance with guidance on navigating US taxes while living outside the country. The company describes its approach as helping clients make the most of exclusions and credits available specifically to expats.
That benefit-focused approach is a good match for expats who are mainly trying to make sure they’re not leaving money on the table through missed exclusions or credits.
What to Compare Before You Pick a Preparer
Not every expat tax situation is the same, so the right service depends on what your return actually involves. A few questions are worth asking before you commit to anyone on this list.
First, do you own a foreign business? If you have any ownership stake in a foreign corporation, you need a preparer who files Form 5471 regularly, not occasionally. This form carries steep penalties starting at $10,000 per form, per year, so experience here isn’t optional.
Second, how complex is your income? A simple salary with foreign tax credits is a very different job than multiple income streams, foreign investments, or a mix of self-employment and corporate ownership across borders. Software-based services tend to work well for the former and struggle with the latter.
Third, do you need to fix past mistakes? If you suspect a prior return was filed incorrectly or incompletely, you want a firm with direct experience correcting past filings, since the IRS treats a self-corrected error differently than one it catches first. This same logic applies to personal finances generally, the way financial writers often point to patient, compounding habits as the foundation of long-term stability rather than short-term fixes.
Finally, check whether pricing is flat or variable. A flat rate means no surprise invoice after your return turns out more complicated than expected. A variable or hourly model can work fine too, but you should know which one you’re signing up for before the engagement starts.
For most expats with a straightforward W-2 and a foreign tax credit or two, several of the services above will do the job well and affordably. But if you own a foreign corporation, have unresolved prior year filings, or just want a team that treats Form 5471 and GILTI reporting as routine rather than rare, Universal Tax Professionals is the clearer fit among this group, built specifically around that kind of complexity rather than around tax filing in general.
