I had four readiness calls in the last two weeks. Four out of five asked some version of the same thing. "I can't work in Costa Rica, but I can hire employees, right?" One was looking at buying a gym. Another wanted a booth at festivals. A third wanted to flip his US house equity into a small Costa Rica rental business. The fourth wanted to do online teaching.
They all had the rule half-right. The rule is real. You can't take a job in Costa Rica until you have permanent residency. But you can own a business. The piece nobody talks about is what that ownership actually triggers on the US side, and which entity you pick changes your tax life in a way most prospects don't see coming.
This post walks through the four pieces that actually matter: the work rule, the entity choice (S.R.L. vs S.A.), the IRS form people miss, and what happens to the money when it flows back to you.
The work rule, the way it actually reads
Costa Rica's immigration law is pretty plain on this. Until you hold permanent residency, you can't be paid a salary by a Costa Rican employer. That applies whether you're on a tourist stamp, temporary residency under pensionado, rentista, or inversionista, or no status at all.
What you CAN do, even on day one: own a Costa Rican corporation, sit on its board, be the sole shareholder, and earn income through ownership rather than employment. You can hire Costa Ricans. You can hire other expats who hold their own work rights. You can collect rent from a property you own. You can take distributions from a business you own. None of that is "work" in the legal sense.
Where people trip up: showing up to teach the classes yourself at the gym you just bought, or being the one selling at the booth you set up. That crosses from owner to worker. The fix is structural, not creative. If your business model requires YOU in the room generating the value, the cleanest path is to start the residency application now and build the timeline around when permanent status lands. Temporary residency requires three years of continuous status before you can apply for permanent in most categories, per the DGME.
The S.R.L. vs S.A. decision (this one matters more than you think)
Costa Rica gives you two practical entity choices for a small business:
S.A. (Sociedad Anónima), the equivalent of a US C-corp. Requires a board, a president, secretary, treasurer, and a fiscal agent. More formal, more compliance.
S.R.L. (Sociedad de Responsabilidad Limitada), closer to a US LLC. Simpler governance, just a manager and shareholders. Less paperwork year to year.
On the Costa Rica side, the choice is mostly a paperwork question. Most expat-owned small businesses end up as S.R.L. because the annual compliance is lighter.
On the US side, the choice is much bigger. The IRS classifies foreign entities under what's called the "check-the-box" rules. A Costa Rican S.A. is on the "per se" corporation list, which means it's automatically treated as a foreign corporation for US tax purposes, and you cannot elect to treat it any other way. A Costa Rican S.R.L. is NOT on the per se list, which means it defaults to a disregarded entity if you're the sole owner, or a foreign partnership if there are multiple owners, and you can elect to be taxed as a corporation if you want.
That difference changes which IRS form you file, whether the business income flows to your personal 1040 each year, and how distributions are treated. For most single-owner expat businesses, the S.R.L. as a default disregarded entity is the cleanest path. Income flows through to your Schedule C or Schedule E (depending on the activity), and you avoid the more complex corporate filings.
Important caveat: tax laws change, and the check-the-box treatment of specific foreign entities has been amended before. Verify the current per se list with your CPA before you file your formation documents, because changing entity classification after the fact is messy.
The IRS form most people miss (and the penalty for missing it)
If you end up owning a Costa Rican S.A., or you elect corporate treatment on an S.R.L., you almost certainly owe Form 5471. This is the IRS information return for US persons who own at least 10% of a foreign corporation. It's filed with your 1040 every year, even in years the corporation has no income.
The penalty for failing to file is $10,000 per form per year, per IRS Form 5471 instructions, and it can stack across multiple years if the failure was ongoing. The IRS has been more aggressive about this since 2022, when they started cross-referencing foreign property ownership with US tax filings.
The flip side: if your business is an S.R.L. structured as a disregarded entity, you don't file Form 5471. You report the activity directly on your Schedule C or Schedule E. If it's a multi-member S.R.L. taxed as a partnership, you file Form 8865 instead, which carries a similar $10,000 penalty.
There's a third form that catches a lot of people. Form 5472, for US-owned foreign corporations engaged in reportable transactions with their US owner, applies in some structures. Your CPA should know which combination of 5471, 5472, and 8865 your specific setup triggers. If they don't ask, that's a flag.
And separately from any of the above, if your Costa Rican business holds a bank account whose balance exceeds $10,000 at any point during the year, you also owe FBAR, the Report of Foreign Bank and Financial Accounts, due April 15 with an automatic extension to October 15. Penalties for non-willful FBAR violations are $16,536 per violation, per the 2026 inflation-adjusted figures from FinCEN. Willful violations are $165,353 or 50% of the account balance, whichever is greater.
I write these numbers down because most of the prospects I talk to assume "I'll figure out the tax stuff once I move." The reporting requirements start the day you sign the formation paperwork. They don't wait for you to land.
How the income actually flows back to you
This is the part where prospects relax once they see it. A small example, generalized from a pattern I see often: someone with a multi-six-figure portfolio, low four-figure monthly spending, buys a small operating business in Costa Rica for around $100,000.
Path one, the S.R.L. as disregarded entity. The business earns, say, $30,000 in profit for the year. That $30,000 flows directly to your Schedule C on your 1040. You pay US income tax on it at your ordinary rates. You also pay Costa Rican income tax on the same income at Costa Rica's corporate rates (10-30%, depending on the bracket, per Costa Rica's DGT). You then claim a foreign tax credit on Form 1116 for the Costa Rican tax paid, which reduces your US tax dollar-for-dollar up to the US tax that would have applied to that income. Net result: you pay the higher of the two rates, not both. Costa Rica being territorial generally doesn't tax your US-source income, only the income generated inside Costa Rica.
Path two, the S.A. or S.R.L. taxed as a corporation. The business earns the $30,000. The corporation pays Costa Rican corporate tax. The remaining profit stays inside the corporation until you take a distribution. When you take a distribution, that's a dividend for US tax purposes, and depending on whether the entity qualifies as a CFC (controlled foreign corporation) and whether it's hit Subpart F or GILTI thresholds, you may owe US tax on undistributed earnings each year regardless of whether you took anything out. This is the trap. Small expat-owned operating businesses can easily hit CFC status because the test is simple: more than 50% US ownership.
For most small expat businesses, the disregarded S.R.L. avoids these traps entirely. That's why the entity decision matters more than people think.
Who this works for, who it doesn't
This works for someone who has the cash to fund the business without selling appreciated US assets at a loss or pulling early from retirement accounts. Pulling $100,000 from a pre-tax 401k to fund a Costa Rica business adds that $100,000 to your US ordinary income for the year, and if you're under 59 and a half, there's an additional 10% early withdrawal penalty, per IRC Section 72(t). I've seen people take that hit, not realize until tax season, and end up with a five-figure surprise bill from the IRS.
This works for someone whose business model genuinely makes sense. "I'll buy a small business so I have something to do" is rarely a good reason to write a six-figure check. A business that was barely breaking even because the previous owner wasn't paying himself becomes unprofitable the moment you have to pay someone (yourself or an employee) to do the work.
This doesn't work for someone who needs to BE the worker. If the value proposition is your skill being applied to customers, and you can't legally apply it until you have permanent residency, you're looking at three years of paying others to deliver what you wanted to deliver. That math rarely works for solo-operator service businesses.
Common mistakes I see
- Forming an S.A. by default because the attorney's template uses S.A., without anyone asking the US tax question.
- Buying the business in your personal name and then trying to retroactively wrap it in a corporation. Costa Rica's transfer taxes apply each time the entity changes.
- Skipping FBAR because "it's just the business account, not a personal account." If you're an owner, you're a signatory, and the threshold applies.
- Underestimating the cash burn. A small Costa Rica business often takes 18-24 months to stabilize, and the previous owner's profit-and-loss reflects their habits, not yours.
- Not getting the seller's financials reviewed by someone neutral. The spreadsheet your realtor prints out is not an audit.
What to do next
If you're seriously considering this, the order of operations I'd suggest:
- Verify the business is actually profitable, not just "the owner doesn't pay himself."
- Decide what residency path you're on (pensionado at $1,000/month lifetime pension, rentista at $2,500/month documented income for two years or a $60,000 deposit, or inversionista at $150,000 invested, per current DGME requirements). Your business purchase can often satisfy inversionista.
- Pick the entity with your US CPA in the room, not after the fact. S.R.L. as default-disregarded is the right choice for most single-owner small businesses.
- Build the IRS reporting calendar into your first year. Form 5471 (or whatever applies), FBAR, Schedule C or E, Form 1116 for the foreign tax credit. Map every form to a date.
- Keep enough US cash on the side to cover 24 months of personal expenses without leaning on the business. The number one reason expat-owned businesses fail is the owner draining the buffer.
If you want a second set of eyes on whether your situation fits this path, I do this through the Costa Rica readiness review. We look at the entity decision, the tax flow, the reporting calendar, and whether the business actually pencils. It's two hours and a flat fee.
