Does Your Foreign Country See Your US LLC the Way the IRS Does?

Making assumptions when it comes to taxes can be expensive. One of the most common assumptions for US citizens living abroad with a US LLC is that the country you live in treats the LLC in the same way as the US. More specifically that both the US and the foreign country will see it as a flow-through vehicle where you pay tax at the individual level and take a credit in the US for any taxes you pay in your local country.

That assumption could be wrong. And when it's wrong, it doesn't just create a paperwork headache - it can leave you paying tax twice on the same income, with no clean way to fix it after the fact.

The Problem: One LLC, Two Tax Systems

Here's the scenario that trips people up. You move abroad, keep running your US LLC, and assume that whatever the IRS taxes you on, your new home country will tax the same way - just with a foreign tax credit smoothing out the difference. If your new country has a higher tax rate than the US, which is true in a lot of popular expat destinations, this should mean you owe little or no income tax to the IRS, since you're already covering the bill locally.

That's how it's supposed to work. The catch is that "supposed to" depends entirely on whether the foreign country agrees with the US on what your LLC actually is for tax purposes. In a lot of cases, it doesn't.

Why the Mismatch Happens

To see why, it helps to know how the IRS treats an LLC in the first place. A single-member LLC is a disregarded entity - the business isn't a separate taxpayer at all. The income flows straight through to you, and you pay tax on the full net profit regardless of how much cash you actually pulled out of the business. Leave every dollar sitting in the business account, and you still owe tax on it as if you'd taken it home. A multi-member LLC works the same way, just taxed as a partnership instead.

Compare that to a US corporation, where the entity itself is the taxpayer. The corporation pays tax on its net income, and you, the owner, only get taxed personally when you take money out as a dividend or sell your shares.

The problem is that plenty of countries don't have a category that matches the US "disregarded entity" concept. Instead of looking through the LLC to the income earned, they treat it as an opaque corporation - a separate taxpayer in its own right. And an opaque entity is only taxed on what it distributes, not on what it earns.

What It Costs You If You Get It Wrong

Run the numbers and the mismatch becomes obvious. Say your LLC nets $100,000 in profit for the year, and you distribute $50,000 of it to yourself. The US taxes you on the full $100,000, because that's how flow-through income works. If your host country treats the LLC as opaque, it only taxes you on the $50,000 you actually took out. Now you've got two different income figures being taxed in two different countries, and the foreign tax credit - which is supposed to prevent double taxation - can't fully reconcile the gap. Do this for a few years running, distributing different amounts each year, and the mismatch compounds instead of correcting itself.

The UK is the clearest example of how messy this can get, mostly because it's the country with the most litigation and formal guidance on the issue. In 2015, a case called Aronson went to the UK Supreme Court - a UK citizen with a US LLC, arguing that HMRC should treat the LLC as a flow-through entity the same way the IRS does, so the foreign tax credit would apply cleanly. The Supreme Court agreed. For a while, expats and their advisors treated Aronson as settled law. Then HMRC issued a statement saying the case had been decided incorrectly and couldn't be relied on going forward.

Since then, several McGowin Tax clients have tried the UK equivalent of a private letter ruling, formally requesting that HMRC treat their LLC as a flow-through entity. Every one of those requests has failed. The conservative position right now is that if you're in the UK with a US LLC, HMRC is going to treat it as a corporation - full stop.

There's a reason to expect that to change. The UK government has put out a consultation proposing to reverse this treatment, explicitly citing the fact that some expats are ending up with effective tax rates north of 75% on their LLC profits because of this exact mismatch. That's a meaningfully different signal than the usual round of complaints from accountants and taxpayers - it's the government itself proposing the fix. It's not law yet, and there's no telling exactly how long the UK's consultation-to-legislation process will take, but the direction is at least encouraging.

How to Structure Around It

The good news is that once you know how a country is going to classify your LLC, you can plan around the mismatch instead of getting caught by it.

Take a McGowin Tax client based in France, where the tax authority often treats US LLCs as opaque corporations. Knowing that in advance, the fix is straightforward: distribute the full net profit - say, that same $100,000 - in the same year it's earned, through a combination of salary and dividend. That way, France is taxing the same $100,000 the US is taxing, in the same tax year, and the foreign tax credit does what it's supposed to do.

The part that matters most here is timing. This only works if you decide on the distribution before the tax year closes. If you leave the money in the business assuming you'll take the same flow-through approach you'd use domestically, and then find out afterward that the host country treated the LLC as a corporation, there's no clean way to go back and unwind that. The mismatch is already locked in, and catching up in a later year just creates a new version of the same problem.

Country-by-Country Considerations

The UK and France aren't unique - this issue shows up anywhere a country's tax code doesn't have a direct equivalent to the US disregarded entity or partnership structure. Some countries have detailed guidance on how they'll treat a US LLC. Others have essentially no written rule at all, which means you're working from general local law and precedent rather than a clear answer.

Tax treaties help coordinate the two systems when they're available, which is a big part of why this is manageable in a country like the UK or France. Latin America is the notable exception - most countries there don't have a US tax treaty, so there's no treaty mechanism to fall back on. That said, some Latin American countries use territorial tax systems, which change the calculus in a different way. Costa Rica and Panama, for instance, generally doesn't tax income earned outside the country at all, regardless of how it classifies a US LLC. In a case like that, the classification question matters less because the local tax bill on foreign-sourced income is minimal or nonexistent to begin with.

What to Do Before Your Next Tax Year Closes

The theme running through all of this is that international tax planning is fundamentally an exercise in coordination - knowing what the US requires, knowing what your host country requires, and using treaties where they exist to bring the two systems into alignment. The one thing you can't do is fix a classification mismatch retroactively. It has to be addressed before the tax year in question ends.

If you're a US citizen living abroad with a US LLC, or you're planning a move and want to structure things correctly from the start, it's worth getting ahead of this rather than discovering the mismatch on next year's return.
