US REITs: the real FIRPTA 21% trap — and why it almost never applies to you
A US REIT's capital gain distribution can be withheld at 21%, with no treaty reduction possible — except that almost every retail investor is protected by the 10% exception on publicly traded REITs. The verified mechanism, and who is genuinely affected.

"Stay away from US REITs, the withholding tax is a trap" — the claim circulates on investor forums, usually without separating two genuinely different mechanisms. One covers a REIT's ordinary dividends (Realty Income, Prologis, an ETF like VNQ...): they follow the exact same rule as any US stock, 30% cut to 15% with a valid W-8BEN. The other covers a much rarer slice of the distribution — the part tied to the fund's sale of a US property — and that's where the France-US tax treaty stops helping at all. Here's exactly where the real line sits, and why it almost never touches a retail investor buying shares directly through a broker.
Two very different withholdings hide under the same word "REIT"
A REIT (Real Estate Investment Trust) pays its shareholders two kinds of distributions, taxed differently on the US side:
- Ordinary dividends, sourced from rental income the fund collects. These are "FDAP" income (Fixed, Determinable, Annual or Periodical) — the exact same category as an Apple or Coca-Cola dividend: 30% at the full statutory rate, 15% with a valid W-8BEN on file with your broker, recoverable after the fact otherwise.
- Capital gain distributions, sourced from the fund's sale of an underlying US property. These aren't FDAP income at all: they're treated as a US real property gain realized directly by you — the FIRPTA (Foreign Investment in Real Property Tax Act) mechanism.
FIRPTA: why the tax treaty reduces nothing on this part
When a distribution is recharacterized as FIRPTA gain (Internal Revenue Code section 897), it leaves the dividend regime entirely: it's taxed as income effectively connected with a US trade or business ("ECI"), at the applicable US rate — not at the treaty-capped 15%. The REIT must withhold 21% on that portion at the time of payment — a rate set by US law itself (section 1445(e)(6)), which no W-8BEN can lower. The IRS's FIRPTA page covers this mechanism in detail. In theory, the recipient must then file a US tax return (Form 1040-NR) to settle their actual liability on that gain.
The exception that protects almost every retail investor: the 10% threshold
US law carries a broad exception, often missing from articles that raise the FIRPTA alarm without nuance: for a publicly traded REIT — regularly traded on an established securities market, which covers the vast majority of REITs accessible through a European broker — a capital gain distribution is not recharacterized as FIRPTA gain if the shareholder held no more than 10% of a class of the fund's stock at any time during the 12 months before the distribution. In that case, the distribution reverts to the ordinary treatment above: 30% cut to 15% by treaty, through the same W-8BEN as any other dividend. This threshold, raised from 5% to 10% by a 2015 law (the PATH Act), remains the rule in effect in 2026.
In practice: a retail investor holding a few dozen or hundred shares of Realty Income, Prologis, or an ETF like VNQ, through an ordinary brokerage account, sits orders of magnitude below the 10% threshold of a publicly traded REIT — often capitalized at tens of billions of dollars. The 21% FIRPTA regime simply doesn't apply to their situation, whatever share of the distribution came from a property sale.
Who is genuinely affected
- Non-traded REITs, sometimes marketed by wealth managers as closed-end funds or private real estate investment vehicles: the 10% exception requires a stock regularly traded on an established securities market, which these aren't — full-rate FIRPTA withholding applies from the very first capital gain distribution.
- An unusually concentrated position in a small-cap, publicly traded REIT, where holding more than 10% of a class of shares would remain materially possible for a retail investor — a rare but non-theoretical case outside the large index REITs.
- A company or structure (a holding vehicle, a civil real estate company) holding the shares rather than an individual holding them directly — the 10% threshold and FIRPTA analysis then work differently, and fall outside the scope of this article.
How to check what actually applies to you
A US broker's Form 1099-DIV includes a dedicated box ("Section 897 gain") that isolates the FIRPTA portion of a distribution precisely — a reliable marker if your account provides one. A European broker doesn't always break this out as clearly: if a US REIT line shows withholding noticeably above 15% despite a valid, current W-8BEN, the first hypothesis to check is still an ordinary rate error — the statement-reading walkthrough here applies the same way. The FIRPTA question only becomes relevant for a non-traded REIT, or a position whose size genuinely approaches the 10% threshold — two situations worth flagging explicitly to a tax professional rather than handling on your own.
Summary table
| Ordinary dividend (rental income) | FIRPTA gain (non-traded REIT or > 10%) | "10% exception" gain (publicly traded REIT, ordinary position) | |
|---|---|---|---|
| Nature of the income on the US side | FDAP (dividend income) | Effectively connected gain (§897) | FDAP (treated as an ordinary dividend) |
| Withholding rate | 30% without a W-8BEN, 15% with one | 21%, set by US law | 30% without a W-8BEN, 15% with one |
| Treaty-reducible? | Yes, via a W-8BEN | No | Yes, via a W-8BEN |
| Path if over-withheld | Over-withholding refund claim (a FiscalPlace case) | Form 1040-NR return — outside FiscalPlace's scope | Over-withholding refund claim (a FiscalPlace case) |
Your questions about US REITs
Should I avoid US REITs because of FIRPTA?
That's not what this mechanism says: for a publicly traded REIT held in an ordinary position, the 10% exception applies in the vast majority of cases, and you stay in the same regime as any US dividend. FiscalPlace neither recommends nor discourages an investment choice — only checking which mechanism actually applies to your situation before deciding.
Does my W-8BEN also protect the FIRPTA capital-gain portion?
No: a W-8BEN reduces the rate on FDAP income (ordinary dividends). It has no effect on a distribution recharacterized as FIRPTA gain, whose 21% rate is set by US law independently of any tax treaty. See our W-8BEN guide for what it actually covers.
How do I know if a given REIT is "publicly traded" for this exception?
A REIT bought like an ordinary stock through a broker — listed on the NYSE, Nasdaq, or traded via an index ETF — meets the criterion in practice. Genuine doubt only gets resolved case by case with a tax professional, particularly for a vehicle offered outside the listed market (a closed-end fund, a non-traded real estate vehicle, a wealth-planning structure).
Can FiscalPlace help if a distribution was withheld at 21% under FIRPTA?
No — that case calls for an actual US income tax return (Form 1040-NR), not a treaty over-withholding refund claim. We'd rather tell you plainly than let you assume we handle a case we don't.
The simulator covers the rate gap on ordinary dividends — not a distribution already recharacterized as FIRPTA gain, which calls for a separate US tax return.
