US FIRPTA Exceptions for Hong Kong Investors: Domestically Controlled REIT and Publicly Traded Exceptions

The US Internal Revenue Service’s enforcement focus on cross-border real estate transactions has sharpened considerably since the implementation of the Foreign Investment in Real Property Tax Act (FIRPTA) withholding regime. For Hong Kong-based investors—whether US citizens, Green Card holders, or Hong Kong tax residents with US real estate exposure—the default 15% withholding on the gross sale price of US real property interests (USRPIs) presents a liquidity challenge and a filing burden. However, two statutory exceptions under IRC § 1445 offer a path to reduced or eliminated withholding: the Domestically Controlled REIT (DC REIT) exception and the Publicly Traded exception. These provisions, codified at IRC § 897(h)(2) and IRC § 1445(b)(6) respectively, are particularly relevant in 2025 as the IRS intensifies its examination of non-US trusts holding US real estate and as Hong Kong family offices increasingly structure US property investments through US-domiciled REITs. Understanding the precise mechanics of these exceptions—including the 50% US ownership threshold for DC REIT status and the regular trading volume requirements for publicly traded entities—is essential for structuring US real estate exits without triggering unnecessary withholding or audit risk.

The Domestically Controlled REIT Exception: Mechanics and the 50% Ownership Threshold

The DC REIT exception under IRC § 897(h)(2) provides that a non-US person’s sale of stock in a domestically controlled REIT is not subject to FIRPTA withholding. A REIT is “domestically controlled” if less than 50% of its stock value is held directly or indirectly by foreign persons during the five-year period ending on the date of disposition. This test is applied on a look-through basis under Treasury Regulations § 1.897-9T.

Determining Foreign Ownership: The Five-Year Look-Back Period

The five-year look-back period is the critical compliance window. For a Hong Kong investor selling REIT shares in 2025, the IRS will examine the REIT’s ownership from 1 January 2020 through the date of sale. If at any point during this period foreign ownership exceeded 50%, the exception is lost and the 15% withholding applies to the gross proceeds. The IRS has provided limited guidance on how to measure “value” for this purpose, but the prevailing view under Notice 2007-55 is that market capitalization at the close of each quarter is the appropriate metric.

Practical Impact for Hong Kong Investors Holding US REITs

For Hong Kong-based investors, the DC REIT exception is most valuable for large-block positions in US-domiciled REITs such as Realty Income (O), Prologis (PLD), or Equity Residential (EQR). If the REIT can demonstrate that less than 50% of its shares are held by foreign persons—a fact typically certified by the REIT’s transfer agent or IRS Form W-9—the investor can sell without FIRPTA withholding. However, the burden of proof falls on the seller. The Hong Kong investor must obtain a written certification from the REIT confirming its DC REIT status, signed under penalties of perjury. Without this certification, the buyer’s escrow agent is required to withhold 15% of the gross sale price.

The “Publicly Traded” Exception under IRC § 1445(b)(6)

A separate and often overlapping exception applies to publicly traded USRPIs. Under IRC § 1445(b)(6), if the USRPI is a class of stock that is regularly traded on an established securities market, the seller is exempt from FIRPTA withholding provided the seller holds no more than 5% of the class of stock at any time during the five-year period ending on the date of sale. The “regularly traded” standard is defined in Treasury Regulations § 1.897-1(c)(2)(iii), which requires that the stock be traded on at least 60 days during the preceding 12-month period and that the aggregate trading volume be at least 10% of the total shares outstanding.

The Intersection of the Two Exceptions: Structuring for Maximum Protection

For Hong Kong investors, the strategic question is whether to rely on the DC REIT exception or the publicly traded exception—or both. The two exceptions are not mutually exclusive, but they operate under different legal frameworks and require different documentation.

When Both Exceptions Apply: The Safe Harbor

If a Hong Kong investor holds less than 5% of the stock of a publicly traded REIT that is also domestically controlled, both exceptions apply. In this scenario, the investor may rely on the publicly traded exception without needing to obtain a DC REIT certification. This is the most common structure for Hong Kong retail investors holding US REITs through brokerage accounts. The key requirement is that the investor must not have held more than 5% of the class at any time during the five-year look-back period.

When Only the DC REIT Exception Applies: Large Blockholders

For Hong Kong investors holding more than 5% of a US REIT—a scenario more common for family offices and institutional investors—the publicly traded exception is unavailable. The investor must rely solely on the DC REIT exception. This requires the REIT to provide a written certification that it is domestically controlled. If the REIT cannot provide this certification—for example, because foreign ownership has fluctuated above 50% during the look-back period—the investor faces full FIRPTA withholding on the sale.

The “Regularly Traded” Standard for Non-REIT USRPIs

The publicly traded exception under IRC § 1445(b)(6) is not limited to REITs. It applies to any class of stock that is regularly traded on an established securities market, including shares of US corporations that own US real estate. For Hong Kong investors holding shares of US real estate operating companies (REOCs) or US homebuilders, the same 5% threshold applies. The IRS has issued guidance in Revenue Procedure 2005-70 on what constitutes an “established securities market,” which includes the New York Stock Exchange, Nasdaq, and certain foreign exchanges.

Reporting Obligations and Penalties for Non-Compliance

Even when an exception applies, the Hong Kong investor is not relieved of all reporting obligations. The FIRPTA withholding exception is a procedural relief for the buyer’s escrow agent, not a substantive exemption from tax. The seller must still report the gain on the sale of the USRPI on a US non-resident tax return (Form 1040-NR) and pay any tax due.

Form 8288 and the Withholding Certificate Process

If the DC REIT or publicly traded exception applies, the buyer’s escrow agent must file Form 8288 (U.S. Withholding Tax Return for Dispositions by Foreign Persons of U.S. Real Property Interests) with a zero withholding amount. The IRS requires the escrow agent to attach a statement describing the basis for the exception. For the DC REIT exception, this statement must include the REIT’s certification. For the publicly traded exception, the statement must include the broker’s confirmation that the seller held no more than 5% of the class.

Penalties for Failure to Withhold

Under IRC § 1461, the buyer’s escrow agent is personally liable for any FIRPTA withholding that should have been made. If the agent fails to withhold and the IRS later determines that an exception did not apply, the agent is liable for the 15% withholding plus interest and penalties. This creates a strong incentive for escrow agents to demand strict compliance with the exception requirements. For Hong Kong investors, this means that even if the exception technically applies, the escrow agent may insist on withholding unless the investor provides the exact documentation specified in the regulations.

Statute of Limitations for FIRPTA Examinations

The IRS has six years from the date of sale to assess additional tax for FIRPTA violations under IRC § 6501(e)(1)(A), compared to the standard three-year statute of limitations. This extended period reflects the IRS’s view that FIRPTA compliance is a high-risk area for non-US persons. Hong Kong investors should retain all documentation related to the DC REIT or publicly traded exception for at least seven years after the sale.

Practical Considerations for Hong Kong Family Offices and HNW Investors

For Hong Kong family offices that hold US real estate through REIT structures, the choice between the DC REIT and publicly traded exceptions has direct implications for liquidity and compliance costs.

The “5% Look-Back” Trap for Family Offices

A common pitfall for Hong Kong family offices is the 5% look-back requirement under the publicly traded exception. If a family office holds a concentrated position in a single US REIT—say, 8% of the outstanding shares—the publicly traded exception is unavailable. The family office must then rely on the DC REIT exception, which requires the REIT to certify its domestic control. If the REIT cannot provide this certification, the family office must either sell the shares through a non-US broker-dealer (which may not be practical) or accept the 15% withholding and file for a refund on Form 1040-NR.

Structuring US Real Estate Investments Through US-Domiciled REITs

For Hong Kong investors who anticipate selling US REIT shares in the future, the optimal structure is to invest through US-domiciled REITs that are domestically controlled. This requires due diligence on the REIT’s ownership profile. The Hong Kong investor should request a copy of the REIT’s most recent IRS Form 8937 (Report of Organizational Actions Affecting Basis of Securities) or the REIT’s annual report, which typically discloses the percentage of shares held by foreign persons. If the foreign ownership percentage is consistently below 50%, the DC REIT exception is likely available.

The Role of the Hong Kong Broker

Hong Kong-based brokers that execute US securities trades are subject to the same FIRPTA withholding rules as US-based brokers. Under Treasury Regulations § 1.1445-1(c), a broker is considered a “transferee” for FIRPTA purposes and must withhold 15% of the gross proceeds if the seller is a foreign person. However, if the stock is regularly traded and the seller holds no more than 5%, the broker may rely on the publicly traded exception without additional documentation. The broker must obtain a certification from the seller on Form W-8ECI or Form W-8BEN, but this certification does not need to address the 5% threshold if the broker has actual knowledge of the seller’s holdings.

Actionable Takeaways for Hong Kong Investors

1. Before selling any US REIT shares, confirm whether the REIT is domestically controlled by requesting a written certification from the REIT’s transfer agent or reviewing the most recent IRS Form 8937.
2. If holding less than 5% of a publicly traded US REIT, rely on the publicly traded exception under IRC § 1445(b)(6) to avoid FIRPTA withholding, but ensure the broker confirms the 5% threshold is met.
3. For family offices holding more than 5% of a single US REIT, structure the sale through a US-domiciled REIT that can certify its DC REIT status to avoid the 15% withholding trap.
4. Retain all documentation—including the REIT’s certification, broker confirmations, and the sale agreement—for at least seven years after the sale to cover the extended six-year statute of limitations under IRC § 6501(e)(1)(A).
5. File Form 8288 with a zero withholding amount through the escrow agent, and attach a detailed statement describing the basis for the exception, to avoid an IRS examination.
