US Tax Implications of Buying Property in Nosara, Costa Rica: What Every American Investor Must Know (2026)
FBAR, FATCA, capital gains, and IRS reporting requirements every American must know before buying real estate in Nosara, Costa Rica.
You've fallen in love with Nosara. Maybe you've stayed at a vacation rental in Playa Guiones, surfed the break at Playa Pelada, or watched the howler monkeys from a jungle-view villa in Garza. The decision to buy feels right.
But before you wire a down payment and sign a purchase agreement, there's a conversation you need to have — with a US-qualified CPA who understands international tax law.
The US taxes its citizens on worldwide income. That means your Nosara rental income, your capital gains when you sell, and potentially even the bank account you open to pay your property taxes all have reporting obligations back in the United States. Most buyers are surprised by this. Some unknowingly skip filings that carry steep penalties.
This guide covers every major US tax implication of buying, owning, and eventually selling property in Nosara, Costa Rica. It is not legal or tax advice — your specific situation requires a qualified professional — but it will ensure you ask the right questions before you close.
The Foundational Rule: The US Taxes Worldwide Income
Unlike most countries, the United States taxes its citizens and permanent residents (Green Card holders) on income earned anywhere in the world, regardless of where they live. If you are a US citizen or Green Card holder and you earn rental income from your Nosara villa, you owe US tax on that income — even if you never bring a dollar of it back to the United States.
This applies whether you:
- Own the property in your personal name
- Own it through a Costa Rican corporation (SA or SRL)
- Own it through a US LLC or trust
- Rent it out seasonally on Airbnb
- Use it personally and rent it only occasionally
The structure matters — a lot — but the obligation to report does not disappear.
Part 1: What You Must Report to the IRS
Rental Income: Schedule E
If you rent your Nosara property for more than 14 days per year, you must report the rental income on your US tax return using Schedule E (Supplemental Income and Loss).
The good news: you can deduct expenses against that income, including:
- Property management fees
- Maintenance and repairs
- Property insurance
- Costa Rica property taxes (Impuesto sobre Bienes Inmuebles)
- Depreciation of the structure (not the land)
- Mortgage interest (if applicable)
- HOA or community road fees
Costa Rica's property tax rate is just 0.25% of the registered value per year — one of the lowest in the hemisphere — so this deduction is modest, but it counts.
The 14-day / 10% personal use rule: If you use the property personally for more than 14 days per year or more than 10% of the days it was rented at fair market value (whichever is greater), the IRS classifies it as a "personal residence used for rental." This limits which expenses you can deduct. Many Nosara buyers who use the property themselves for several weeks a year fall into this category, so understand it before you file.
Passive Activity Rules
Foreign rental income is passive income under IRS rules. If your rental generates a loss (after expenses and depreciation), that loss can only offset other passive income — not your wages or business income — unless you qualify as a real estate professional under IRC Section 469, which has strict hour-based requirements.
For most Nosara buyers who have day jobs or businesses in the US, this means losses on paper may be "suspended" and carried forward until you sell.
Part 2: FBAR — The Foreign Bank Account Report
Virtually every Nosara property owner eventually opens a Costa Rican bank account. You'll need one to pay property taxes, utilities, HOA fees, and contractor invoices locally. That account creates a US reporting obligation.
You must file an FBAR (FinCEN Form 114) if:
- You are a US person (citizen, Green Card holder, or US-domiciled resident)
- You have a financial interest in or signature authority over at least one foreign bank or financial account
- The combined aggregate value of all foreign accounts exceeded $10,000 at any point during the calendar year
The FBAR is filed separately from your tax return — it goes to FinCEN (Financial Crimes Enforcement Network), not the IRS — through the BSA e-filing portal. The deadline is April 15, with an automatic extension to October 15.
Penalties for non-compliance are severe:
| Violation Type | Penalty |
|---|---|
| Non-willful failure to file | Up to $10,000 per year per account |
| Willful failure to file | Greater of $100,000 or 50% of account balance per year |
| Willful failure (criminal) | Up to $250,000 fine and/or 5 years imprisonment |
Many Nosara buyers open accounts at Banco Nacional, BAC San José, or Scotiabank Costa Rica without realizing the FBAR is required. If you have prior years where you failed to file, the IRS Voluntary Disclosure Program and the Streamlined Filing Compliance Procedures exist specifically for this situation — talk to a specialist before those years come up in an audit.
Part 3: FATCA — Form 8938
FATCA (the Foreign Account Tax Compliance Act) requires US taxpayers to report specified foreign financial assets on Form 8938, attached to your annual tax return.
Important distinction from FBAR: A foreign real estate property you own in your personal name is not a "specified foreign financial asset" under FATCA. The property itself does not need to be reported on Form 8938.
However, FATCA does apply to:
- Foreign bank and financial accounts (overlapping with FBAR)
- Ownership interests in foreign entities (like a Costa Rican SA or SRL that holds the property)
- Foreign investment accounts
Filing thresholds for Form 8938:
| Filing Status | Living in the US | Living Abroad |
|---|---|---|
| Single / MFS | $50,000 year-end OR $75,000 anytime | $200,000 year-end OR $300,000 anytime |
| Married filing jointly | $100,000 year-end OR $150,000 anytime | $400,000 year-end OR $600,000 anytime |
If you own your Nosara property through a Costa Rican corporation, the value of your interest in that corporation counts toward the FATCA threshold. For properties worth $500,000+, most buyers using a corporate structure will breach these thresholds.
Part 4: Owning Through a Corporation — Additional Reporting
The majority of properties in Nosara — particularly anything with beachfront access or ocean views — are sold through Costa Rican corporations (Sociedad Anónima or SRL) rather than direct title. This is normal and often legally sound practice, but it creates additional US reporting layers.
Form 5471: Information Return for Foreign Corporations
If you own 10% or more of a foreign corporation (including a Costa Rican SA or SRL that holds your property), you must file Form 5471 annually. This is an information return — not a tax payment — but it is one of the most complex forms in the US tax code. Failure to file carries a $10,000 penalty per year per form, with additional penalties if the IRS has to request the information.
PFIC Rules
If the Costa Rican corporation holds passive assets (real estate held for investment rather than active business), it may be classified as a Passive Foreign Investment Company (PFIC) under US tax law. PFIC treatment can result in punitive tax rates on gains. Most individual property-holding SAs fall into this category. A competent international tax advisor will structure the ownership to mitigate PFIC exposure where possible.
The US LLC Alternative
Some US buyers purchase Nosara property through a US LLC, which then holds the Costa Rican property directly or owns shares of the Costa Rican corporation. This structure can simplify US-side reporting (a single-member LLC is disregarded for US tax purposes) but does not eliminate Costa Rican legal requirements. This is an advanced structure that requires both US and Costa Rican legal counsel.
Part 5: Capital Gains When You Sell
This is where the tax picture gets most complex — and where the lack of a US-Costa Rica tax treaty matters most.
Costa Rica's Capital Gains Tax
Costa Rica introduced a capital gains tax on real estate in 2019. Here's how it works for foreign sellers:
| Situation | Tax Rate |
|---|---|
| Property purchased before July 1, 2019 | 2.25% of the sale price (simplified option) |
| Property purchased after July 1, 2019 | 15% of the net gain (sale price minus acquisition cost) |
| Commercial property | 30% of the net gain |
| Non-resident seller | 2.5% withheld by buyer at closing on the transfer value |
For most non-resident US buyers selling a Nosara villa, the buyer's attorney will withhold 2.5% of the gross sale price at closing and remit it to Costa Rica's tax authority (Hacienda). This is a withholding mechanism — you may owe more or receive a refund depending on your actual gain — and you'll need to file with Hacienda to reconcile.
US Capital Gains Tax on the Same Sale
The US will also tax your gain. If you held the property for more than one year, the gain qualifies for long-term capital gains rates — currently 0%, 15%, or 20% depending on your income, plus the 3.8% Net Investment Income Tax (NIIT) if your income exceeds $200,000 (single) or $250,000 (married).
How to calculate your US gain:
- Start with the sale price in USD (Nosara transactions are almost always denominated in USD)
- Subtract your adjusted basis: purchase price + closing costs paid at acquisition + capital improvements made during ownership
- The difference is your taxable gain
The Foreign Tax Credit: Avoiding Double Taxation
Since the US and Costa Rica do not have a tax treaty, the primary tool to avoid paying full tax to both countries is the Foreign Tax Credit (Form 1116). You can credit taxes actually paid to Costa Rica against your US tax liability on the same income — dollar for dollar, up to your US tax rate.
Example: You sell a Nosara villa for $800,000. Your gain is $300,000. Costa Rica taxes the gain at 15% = $45,000. Your US federal tax at 20% + 3.8% NIIT = $71,400. You apply the $45,000 Costa Rican tax as a credit against your US bill. Net US tax owed: approximately $26,400. Total worldwide tax: $71,400 — not $116,400.
The Foreign Tax Credit does not eliminate all tax — it prevents you from being taxed twice on the same dollar — but it significantly reduces double taxation.
Part 6: Currency and Exchange Rate Considerations
Nosara real estate transactions are almost universally priced and settled in US dollars, which simplifies currency reporting for most buyers. However, if you:
- Earn rental income in Costa Rican colones (₡)
- Pay expenses in colones
- Hold colones in a local account
...you must convert all amounts to USD using the exchange rate on the date of the transaction. Currency gains and losses on foreign-denominated transactions are reportable as ordinary income under IRC Section 988 in some circumstances. For most Nosara investors operating in USD throughout, this is not a significant complication — but it is worth confirming with your CPA.
Part 7: The Foreign Earned Income Exclusion — What It Does NOT Cover
If you relocate to Nosara full-time and establish bona fide residency, you may qualify for the Foreign Earned Income Exclusion (FEIE) via Form 2555, which allows you to exclude up to $130,000 (2025 indexed figure) of foreign-earned income from US tax.
Critical limitation: The FEIE covers earned income only — wages and self-employment income. It does not apply to:
- Rental income
- Capital gains on property sales
- Dividend or interest income
If your primary income from your Nosara property is rental income, the FEIE does nothing to reduce your US tax on it. Rental income is always passive income, taxed at ordinary rates, offset only by the Foreign Tax Credit.
Practical Checklist: Before You Close on a Nosara Property
Confirm each of these with your advisors before signing:
- Choose your ownership structure — personal name, Costa Rican SA/SRL, US LLC, or trust — and understand the US reporting implications of each
- Hire a US-qualified international CPA — not just a Costa Rican accountant
- Understand your FBAR obligation — will you open a local bank account? What will the balance be?
- Determine Form 5471 applicability — if buying through a Costa Rican corporation, this is likely required annually
- Model the rental income scenario — Schedule E, passive activity limits, depreciation
- Plan for the eventual sale — document your cost basis carefully, including all improvements
- Set up a system to track expenses in USD — critical for both Schedule E deductions and capital gains basis
Working With the Right Professionals
Most general US CPAs have never handled a foreign property transaction. You need someone who specifically handles international real estate tax. Look for credentials including a CPA with international tax experience, an Enrolled Agent with international background, or an attorney with both US and Costa Rican qualifications.
In Nosara and the broader Guanacaste region, several law firms have established relationships with US-qualified tax advisors who provide coordinated advice on both sides. Ask your Nosara real estate attorney for referrals — they work with these cross-border specialists regularly.
The Bottom Line: Nosara Is Worth It — With Eyes Open
None of this should scare you off. Thousands of Americans own property in Nosara, operate successful vacation rentals, and navigate the US tax requirements each year without drama. The Foreign Tax Credit system largely prevents true double taxation. The FBAR and Form 5471 filings, while tedious, are manageable with the right professional support.
What causes real problems is discovering these obligations after the fact — years of unfiled FBARs, incorrect Schedule E treatment, or a sale that triggers surprise capital gains calculations with no documented basis.
Go in with your eyes open. Get the right advisors in place before you close. Then enjoy everything Nosara has to offer — the surf, the wellness culture, the community — knowing your investment is structured correctly.
