Why Non-Resident Buyers Face a Different Tax Playbook

Ever wondered why your friend from Toronto paid almost nothing in taxes on her Florida condo sale, while your cousin from São Paulo got hit with a hefty withholding bill on his? The answer isn’t luck—it’s structure, timing, and knowledge of rules most buyers never hear about until it’s too late.

In 2026, foreign buyers continue to represent a meaningful slice of the US real estate market, with the National Association of Realtors reporting that international buyers purchased over $56 billion in US residential property during the most recent reporting period. Yet a surprising number of these buyers approach the transaction the same way a US citizen would—and that’s where the trouble starts.

Here’s the straight talk: the US tax code doesn’t treat non-resident aliens (NRAs) the same way it treats citizens or green card holders. From the moment you sign a purchase agreement to the day you eventually sell, different rules apply—and missing even one can cost you tens of thousands of dollars.

FIRPTA: The Withholding Tax That Catches Buyers Off Guard

The Foreign Investment in Real Property Tax Act (FIRPTA) is the single most misunderstood rule among non-resident sellers. It doesn’t apply when you buy—it applies when you sell, but you need to plan for it from day one.

How FIRPTA Withholding Actually Works

Under FIRPTA, when a foreign person sells US real property, the buyer (yes, the buyer) is required to withhold 15% of the gross sales price and send it to the IRS. This isn’t 15% of your profit—it’s 15% of the entire sale amount, regardless of whether you made money on the deal.

Example: Maria, a non-resident from Mexico, bought a condo in Miami for $400,000 in 2021 and sold it in early 2026 for $520,000. Even though her gain was $120,000, the closing agent withheld $78,000 (15% of $520,000) at closing. Maria later filed a US tax return to reclaim the excess withholding above her actual tax liability—but she had to wait nearly eight months for her refund.

Reducing or Avoiding FIRPTA Withholding

The good news: you can often reduce this withholding legally. If the buyer intends to use the property as a personal residence and the sales price is $300,000 or less, withholding can be eliminated entirely. Between $300,000 and $1,000,000, a reduced 10% rate may apply under the same personal-residence exemption. Sellers can also apply for a withholding certificate (Form 8288-B) before closing, which allows the IRS to approve a reduced withholding amount based on actual anticipated tax liability rather than the full 15%.

Income Tax on Rental Property: Two Paths, Two Outcomes

If you’re buying US property to rent out, you face a choice that dramatically affects your tax bill: how will your rental income be taxed?

The Default: 30% Flat Withholding Tax

Without any election, the IRS treats rental income earned by non-residents as “Fixed, Determinable, Annual, or Periodical” (FDAP) income, taxed at a flat 30% of gross rental income—no deductions for mortgage interest, property taxes, repairs, or depreciation allowed.

The Smarter Path: Net Income Election Under IRC Section 871(d)

Most experienced non-resident investors instead file an election to treat rental income as “effectively connected” with a US trade or business. This allows taxation on net income after deducting expenses, using the same graduated rates that apply to US taxpayers (10% to 37% in 2026, depending on income bracket). For a property generating $30,000 in gross rent with $22,000 in deductible expenses, this election could mean paying tax on just $8,000 instead of the full $30,000.

As one cross-border tax advisor put it: “The 30% withholding rule punishes investors who don’t plan ahead. The election isn’t automatic—you have to file it, and if you miss the deadline, you may lose the benefit for that tax year.”

Estate Tax Exposure: The $60,000 Trap

This is the rule that shocks even sophisticated foreign investors. US citizens enjoy an estate tax exemption of roughly $13.99 million in 2026. Non-resident aliens who own US-situs property—including real estate—get an exemption of just $60,000.

That means if a non-resident owns a $1.5 million California home directly in their own name and passes away, their estate could face federal estate tax of up to 40% on the value exceeding $60,000—a bill that could easily exceed $500,000, payable before heirs can even transfer the title.

Case in point: A UK national purchased a $2 million vacation home in Aspen and held it in her personal name. When she passed away unexpectedly in 2025, her estate owed nearly $770,000 in US federal estate tax alone, on top of probate costs and delays that kept her heirs locked out of the property for over a year.

Comparing Ownership Structures

Choosing the right ownership vehicle is arguably the single most important decision a non-resident buyer makes. Here’s how the main options stack up:

To put the estate tax exposure into perspective, here’s how a $2 million property held under different structures compares in potential estate tax liability:

Common Challenges and How to Overcome Them

Beyond the headline rules, three recurring problems trip up non-resident buyers year after year.

1. Missing the ITIN requirement. Non-residents need an Individual Taxpayer Identification Number to file returns, claim FIRPTA refunds, or make income elections. Applying at the last minute before closing often causes delays of six to ten weeks. Apply early, ideally as soon as you begin house hunting.

2. Assuming tax treaties automatically apply. Not every country has a tax treaty with the US, and even those that do don’t necessarily reduce FIRPTA or estate tax exposure. Always verify treaty benefits with a cross-border specialist rather than assuming they apply.

3. Ignoring state-level taxes. Federal rules get most of the attention, but states like California and New York impose their own withholding and income tax rules on property sales, sometimes adding another 3% to 13% withholding on top of FIRPTA.

Pro Tip: Build your tax strategy before you make an offer, not after you close. The structure you choose on day one shapes your tax bill on the way in, during ownership, and on the way out.

FAQs

Do I have to pay FIRPTA withholding when I buy US property?

No. FIRPTA withholding applies to the seller at the time of sale, not the buyer at the time of purchase. However, if you’re buying from another non-resident, you as the buyer may be responsible for withholding and remitting the tax on their behalf.

Can I avoid the $60,000 estate tax exemption problem entirely?

Yes, in many cases. Structuring ownership through a foreign corporation, a properly drafted trust, or a layered LLC arrangement can significantly reduce or eliminate US estate tax exposure. The right structure depends on your home country, treaty status, and long-term goals, so professional guidance is essential.

Is rental income from my US property automatically taxed at 30%?

Only if you don’t make an election. Filing the net income election under Section 871(d) lets you deduct expenses and pay tax at graduated rates instead, which is usually far more favorable for actively managed rental properties.

Your Roadmap Forward

Buying US property as a non-resident isn’t just a real estate transaction—it’s a cross-border financial decision with consequences that stretch decades into the future. As global capital continues flowing into US real estate through 2026 and beyond, tax authorities are only getting sharper about enforcement, making proactive planning more valuable than ever.

• Step 1: Decide on your ownership structure before signing any purchase agreement.
• Step 2: Apply for your ITIN early to avoid closing delays and refund bottlenecks.
• Step 3: File the net income election if you plan to rent the property out.
• Step 4: Review your estate tax exposure and consider a trust or corporate layer if your property value exceeds $500,000.
• Step 5: Work with a cross-border tax professional who understands both your home country’s rules and US requirements.

You wouldn’t build a house without a blueprint—so why buy one without a tax plan? The buyers who thrive in the US market aren’t the ones who avoid complexity; they’re the ones who plan for it before it becomes a costly surprise.
