A real estate sponsor based in Miami is midway through raising a $20 million fund under Rule 506(b). Twelve domestic accredited investors have committed, and the offering has been cleanly structured and marketed to pre-existing contacts. Two prospective investors then emerge: a family office based in Toronto and an individual investor residing in Singapore. Both are interested in the same investment strategy, both can write meaningful checks, and neither has any prior relationship with the domestic U.S. securities law framework that would make them ineligible under Rule 506(b) on accreditation grounds alone.
The sponsor wants to admit them into the existing fund. The sponsor’s securities counsel identifies two problems. The first is the Regulation S question: are the offshore transaction requirements satisfied for investors who are non-U.S. persons and whose transactions are completed outside the United States? The second is the FIRPTA and partnership withholding question: what are the U.S. tax withholding obligations on these investors’ allocable share of the fund’s effectively connected taxable income and on eventual disposition distributions?
The sponsor had been treating these as a single admission question: can these investors join the existing fund? The correct framing is two parallel compliance questions: what exemption covers their admission, and what ongoing tax withholding obligations does their participation create? Getting the first question right without addressing the second is a structure that works as a securities matter but fails as a tax compliance matter when the fund’s first property sale triggers withholding obligations that the fund’s operating agreement and administrative infrastructure were not designed to handle.
This post addresses how parallel fund structures accommodate U.S. and non-U.S. investors in the same investment strategy, what Regulation S requires and where its most consequential compliance obligations arise, how FIRPTA and Section 1446 partnership withholding operate for foreign investors in real estate funds, how the combined Regulation D and Regulation S structure works within a single fund entity, and when a true parallel fund structure across separate vehicles is preferable to a combined offering in a single vehicle.
Why Non-U.S. Investors Require a Separate Legal Analysis
Domestic real estate fund structures are designed around U.S. investors whose tax and regulatory profiles are addressed by the Regulation D exemption framework, the accredited investor eligibility standard, and the domestic partnership tax rules. When non-U.S. investors join the same fund, they bring two distinct compliance frameworks that the domestic structure was not designed for: a securities law framework governing how their admission is exempt from U.S. registration, and a tax framework governing the withholding obligations their U.S. real estate investment creates.
Those two frameworks operate simultaneously and independently. Regulation S addresses the securities offering exemption mechanics for the non-U.S. investors’ admission. FIRPTA and the partnership withholding provisions of Section 1446 address the tax consequences of their participation. A sponsor who satisfies Regulation S but ignores FIRPTA has a compliant securities structure and an unmanaged tax obligation. A sponsor who addresses FIRPTA but conducts the offering improperly under Regulation S has solved the tax problem and created a securities violation. Both frameworks must be addressed together before a single non-U.S. investor is admitted.
The practical consequence is that admitting non-U.S. investors is not an administrative extension of the domestic investor onboarding process. It requires analysis by securities counsel (for the Regulation S exemption mechanics), tax counsel (for the FIRPTA and Section 1446 withholding analysis), and often offshore counsel (if the investor is in a jurisdiction where offshore counsel is required to confirm local transfer restrictions or regulatory status). As addressed in the prior post in this series on master-feeder structures in real estate funds, the offshore investor’s tax profile may also require a blocker entity or offshore feeder vehicle rather than direct admission to the domestic fund, depending on the investor’s UBTI and ECI exposure.
Regulation S: The Securities Framework for Non-U.S. Investor Admissions
Regulation S under the Securities Act of 1933 provides a safe harbor from U.S. registration requirements for offers and sales of securities that occur outside the United States to non-U.S. persons. Its foundational premise is geographic: the Securities Act’s registration provisions are designed primarily to protect U.S. investors, and transactions that are genuinely offshore between non-U.S. parties, conducted outside U.S. markets, without directed selling efforts in the United States present a different policy case for the registration requirement.
For a real estate fund sponsor, Regulation S functions almost exclusively as a complement to a domestic Regulation D offering rather than as a standalone exemption. The domestic tranche of the offering is conducted under Rule 506(b) or 506(c) for U.S. investors. The offshore tranche is conducted under Regulation S for non-U.S. investors. Both investor populations may hold interests in the same fund entity, but their admission is governed by different legal frameworks that must each be independently satisfied.
The Offshore Transaction Requirement
For an offering to qualify under Regulation S, the offer and sale must be made in an offshore transaction. An offer or sale is in an offshore transaction if the offer is not made to a person in the United States, and either the buyer is outside the United States at the time the buy order is originated or the transaction is executed on a physical trading floor outside the United States. For a private real estate fund admission, this means the non-U.S. investor must be outside the United States when they sign the subscription agreement and when the admission closes.
The offshore transaction requirement is not satisfied by a non-U.S. investor who is physically located in the United States at the time of subscription, even if that investor is a foreign national and even if the investor’s permanent residence is abroad. A Canadian family office representative who signs the subscription agreement while attending a conference in New York has not completed an offshore transaction. The timing of physical location matters, and the subscription documents should confirm each non-U.S. investor’s location at the time of purchase as part of the Regulation S compliance record.
The Directed Selling Efforts Prohibition
The directed selling efforts prohibition is the Regulation S compliance requirement that most frequently catches sponsors by surprise. No marketing activity may be conducted in the United States in connection with the Regulation S portion of the offering. This prohibition applies to communications that condition the market for the offering, arouse investor interest, or invite non-U.S. person investors, even if those communications simultaneously serve the domestic offering’s marketing purposes.
A sponsor’s publicly accessible website that describes the current offering is accessible to non-U.S. viewers. If that website content is also the vehicle through which non-U.S. investors learn about the offering and develop interest in it, the content may constitute directed selling efforts in the United States in connection with the Regulation S portion of the offering. The resolution requires maintaining clear separation between domestic marketing materials (directed at U.S. investors and processed through the domestic exemption tranche) and offshore-directed communications specifically designed for the non-U.S. investor population and not deployed through channels that reach U.S. audiences.
The Restricted Period and Transfer Restrictions
Securities sold under Regulation S are subject to a restricted period during which they may not be resold or transferred to U.S. persons without an independent registration exemption. For Category 3 equity securities of U.S. domestic issuers, which includes most private real estate fund interests, the restricted period is one year from the later of the date of the offering’s completion or the date of the investor’s acquisition. During the restricted period, the non-U.S. investor may transfer their interest only to another non-U.S. person in an offshore transaction or to a U.S. accredited investor through an independent Regulation D exemption.
The transfer restrictions must be documented in the operating agreement and reflected in the subscription agreement’s representations and covenants. The operating agreement should specify that interests held by non-U.S. persons are subject to the Regulation S restricted period, that transfers to U.S. persons during that period are prohibited without an independent exemption, and that the manager has the authority to refuse registration of any transfer that would violate the Regulation S restrictions.
| 📌 Combined Regulation D and Regulation S in a Single Fund Entity: The Two-Tranche Structure A real estate fund that admits both U.S. and non-U.S. investors in the same entity simultaneously must independently satisfy two exemptions, each with its own conditions. The domestic tranche, under Rule 506(b) or Rule 506(c), governs U.S. investor admissions. Under Rule 506(b), investors must be accredited (or sophisticated non-accredited), there can be no general solicitation, and the sponsor must have pre-existing substantive relationships with all investors. Under Rule 506(c), all investors must be accredited and verified, but general solicitation is permitted. The offshore tranche, under Regulation S, governs non-U.S. investor admissions. The transactions must be completed offshore, there can be no directed selling efforts in the United States in connection with the offshore tranche, and the interests are subject to a one-year restricted period from resale to U.S. persons. The two-tranche structure requires that the offering documents address both exemptions. The PPM must describe both the domestic and offshore exemption frameworks. The subscription agreement must include appropriate representations distinguishing U.S. investors (who make accreditation representations) from non-U.S. investors (who make offshore transaction and non-U.S. person representations, agree to transfer restrictions, and acknowledge the restricted period). The operating agreement must specify the transfer restrictions applicable to Regulation S interests and the enforcement mechanism for those restrictions. The most significant operational complication in the two-tranche structure is secondary transfers. A non-U.S. investor who wants to sell during the restricted period must find either another non-U.S. person in an offshore transaction or a U.S. accredited investor through an independent exemption. A U.S. investor who wants to sell must find an accredited investor transferee. Cross-category transfers, a U.S. investor selling to a non-U.S. person or vice versa, require specific legal analysis before closing. |
FIRPTA and Partnership Withholding: The Tax Compliance Framework
The Foreign Investment in Real Property Tax Act imposes U.S. income tax on gains from the disposition of U.S. real property interests by non-U.S. persons. For a foreign investor in a domestic real estate fund, FIRPTA operates through two distinct mechanisms: Section 1446(a) withholding on effectively connected taxable income allocated to the foreign partner, and Section 1446(f) withholding on secondary transfers of partnership interests by foreign partners.
Section 1446(a): Partnership-Level Withholding on ECTI
When a domestic real estate fund earns effectively connected taxable income, which includes income from U.S. real estate operations and gains from the disposition of U.S. real property interests, the fund is required to withhold U.S. tax on the foreign partner’s allocable share of that ECTI. The withholding rate under Section 1446(a) is the highest rate applicable to the foreign partner: 37% for non-corporate foreign partners or 21% for corporate foreign partners.
The fund administrator must calculate and remit the Section 1446(a) withholding using Form 8804 (Annual Return for Partnership Withholding Tax) and Form 8805 (Foreign Partner’s Information Statement of Section 1446 Withholding Tax). The withholding is remitted in quarterly installments based on the fund’s estimated ECTI allocations to each foreign partner. Form 8804 is filed annually with the IRS, and Form 8805 is provided to each foreign partner so they can claim credit for the withheld amounts on their U.S. tax return.
The Section 1446(a) withholding obligation is a fund-level obligation that requires the fund’s administrator to identify every foreign partner, calculate their ECTI allocation, and remit the appropriate withholding quarterly. That infrastructure does not exist in a domestic-only fund and must be built before the first foreign partner is admitted. The operating agreement must give the manager explicit authority to withhold from foreign partner distributions for ECTI tax purposes and to comply with all applicable tax withholding and reporting obligations.
Section 1446(f): Withholding on Secondary Transfers of Partnership Interests
Section 1446(f) of the Internal Revenue Code, added by the Tax Cuts and Jobs Act of 2017 for transfers after December 31, 2017, requires the transferee in a secondary purchase of a partnership interest from a foreign partner to withhold 10% of the amount realized by the foreign seller, when any portion of the gain on the transfer would be treated as effectively connected income. The withholding obligation falls on the buyer, not the seller, which requires any prospective buyer of a fund interest from a foreign partner to account for the withholding obligation before closing the transfer.
The fund’s operating agreement must address Section 1446(f) withholding in the transfer restriction framework. The manager should have the authority to require any buyer of a foreign partner’s interest to withhold and remit the required amount before the transfer is registered on the fund’s books. Certifications and treaty elections that may reduce or eliminate the 1446(f) withholding should also be addressed in the transfer process.
FIRPTA Exceptions and Withholding Certificates
Several exceptions and planning opportunities can reduce or eliminate FIRPTA withholding obligations for specific categories of foreign investors. The domestically controlled REIT exception eliminates FIRPTA on distributions from a REIT that is less than 50% foreign-owned during the testing period. The qualified foreign pension fund exception, significantly expanded by the PATH Act, exempts certain foreign pension funds and their wholly-owned subsidiaries from FIRPTA. And a foreign investor may apply to the IRS for a withholding certificate using Form 8288-B to reduce or eliminate withholding based on the actual expected tax liability, though the IRS typically requires at least 90 days to act, requiring advance planning relative to the transaction’s expected timing.
Tax counsel with specific FIRPTA and partnership withholding experience must be engaged before any non-U.S. investor is admitted. The withholding calculations at the fund level, the Form 8804 and 8805 filing obligations, treaty election procedures for eligible foreign investors from treaty countries, and the Section 1446(f) mechanics for secondary transfers are specific technical requirements that require dedicated tax expertise distinct from the general real estate and securities counsel the sponsor already has.
When to Use a Separate Offshore Parallel Vehicle Instead of a Combined Single-Entity Structure
The two-tranche structure within a single fund entity is efficient when the number of non-U.S. investors is small, when each non-U.S. investor’s tax profile is straightforward, and when the ECTI withholding and Regulation S compliance can be managed through additional provisions in the existing fund documents without materially complicating the domestic investors’ experience. It is the structure the handbook identifies as appropriate for the scenario in the opening of this post: two non-U.S. investors admitted to an existing fund through a Regulation S offshore tranche added to the domestic offering.
A separate offshore parallel vehicle becomes preferable when the volume of non-U.S. investors is large enough that their tax and regulatory requirements would impose meaningful operational complexity on the domestic fund’s administration. A fund that eventually has twenty non-U.S. investors from eight countries, each with different withholding rates, different treaty positions, and different reporting requirements, is a fund whose administration is substantially more complex than a domestic-only fund of the same size. Separating the non-U.S. investors into a dedicated offshore parallel vehicle, organized in the Cayman Islands or another standard offshore jurisdiction, concentrates that complexity in the offshore vehicle without affecting the domestic fund’s administration.
A separate offshore parallel vehicle is also appropriate when the non-U.S. investor population includes investors who require an offshore corporate structure for ECI blocking purposes, where a simple offshore tranche in a domestic LP is insufficient because the investors need a corporate-taxed entity rather than a transparent partnership to avoid ECI flowing through to them directly. In those cases, the offshore vehicle is typically an offshore C corporation or a Cayman exempted company that invests alongside the domestic fund in each acquisition.
Coordination Mechanics: How Parallel Vehicles Invest in the Same Assets
Whether the non-U.S. investor participation is structured as an offshore tranche within the domestic fund or as a separate offshore parallel vehicle, the coordination mechanics determine how the two investor populations participate in the same acquisitions proportionately and how economics are allocated between them.
In the single-entity two-tranche structure, coordination is straightforward: all investors hold interests in the same entity, which owns the same assets. The economics flow through a single waterfall structure to all investors, with the only distinction being the different securities exemptions governing each investor group’s original admission and the different tax withholding obligations applicable to non-U.S. partners.
In a true parallel vehicle structure, each acquisition involves two co-investing funds, each holding a proportionate undivided interest in the property-level SPV. The domestic fund and the offshore parallel fund invest side by side, each holding their pro rata share of the SPV’s equity, with the investment decisions made by the same management entity for both. The coordination documentation must specify that the two funds will participate in each acquisition on substantially similar economic terms, how capital is called from each fund’s investors proportionately, how expenses are shared between the two vehicles, and how distributions from the SPV flow back to each fund and then to each fund’s investors. As addressed in the prior post in this series on LLC or LP choosing the right legal structure for your real estate fund, the LP structure’s explicit framework for investor rights and management authority makes it well-suited for both the domestic and offshore parallel fund vehicles in this context.
The key coordination principle for both structures is that U.S. and non-U.S. investors must participate in the same underlying economic opportunity on substantially similar terms. A structure that provides non-U.S. investors with materially different economics, fewer rights, or different fee treatment than U.S. investors in the same acquisition is a structure that should be disclosed and analyzed for consistency with the fund’s governing documents and investor expectations.
| ⚠️ The Six Compliance Failures That Most Frequently Occur When Non-U.S. Investors Are Admitted to Domestic Real Estate Funds 1. Treating non-U.S. investor admission as an extension of the domestic investor onboarding process without a separate Regulation S analysis. Non-U.S. investors’ admissions require independent satisfaction of Regulation S’s offshore transaction, directed selling efforts, and transfer restriction conditions. A completed domestic questionnaire and accreditation verification does not substitute for the Regulation S compliance analysis. 2. Failing to confirm the non-U.S. investor’s physical location at the time of subscription to establish the offshore transaction requirement. A non-U.S. investor who signs the subscription agreement while physically in the United States has not completed an offshore transaction regardless of their domicile, nationality, or permanent residence. 3. Conducting domestic marketing through publicly accessible channels that reach non-U.S. viewers without analyzing whether that activity constitutes directed selling efforts in connection with the Regulation S tranche. A website, social media post, or webinar that is accessible to non-U.S. viewers and describes the offering in terms that would arouse their investment interest may constitute directed selling efforts that compromise the Regulation S exemption. 4. Failing to build Section 1446(a) withholding infrastructure before the first non-U.S. investor is admitted. The fund must identify each foreign partner, calculate their ECTI allocations, and remit quarterly withholding installments with annual filing of Form 8804 and provision of Form 8805 to each foreign partner. Those are administrative obligations that must be built into the fund’s administration infrastructure, not addressed reactively when the first property sale triggers the withholding obligation. 5. Not addressing Section 1446(f) withholding in the operating agreement’s transfer restrictions. A buyer of a fund interest from a non-U.S. partner must withhold 10% of the amount realized unless an exception applies. The operating agreement must give the manager authority to require and confirm compliance with this withholding before registering any secondary transfer from a foreign partner. 6. Adding a Regulation S offshore tranche to an existing domestic offering without updating the PPM, subscription agreement, operating agreement, and investor questionnaire to address the offshore compliance requirements. Each of those documents must address the Regulation S conditions, the restricted period transfer restrictions, and the tax withholding framework for non-U.S. investors before any offshore tranche investor is admitted. |
The Parallel Structure That Works Is Built Before the First Offshore Investor Subscribes
The scenario in the opening of this post describes a sponsor who was treating two distinct compliance questions as a single admission decision. Can these non-U.S. investors join the existing fund? The answer to that question requires addressing both the Regulation S exemption mechanics and the FIRPTA and Section 1446 withholding obligations simultaneously, before the subscription agreement is signed.
A sponsor who builds the Regulation S offshore tranche into the fund’s offering documents from the beginning, or who supplements the existing documents before any non-U.S. investor is approached, and who engages both securities counsel and tax counsel to confirm the compliance framework before admission, has a parallel structure that functions as designed when the first non-U.S. investor closes. A sponsor who admits non-U.S. investors informally and addresses the compliance questions after the fact has created both a securities exemption problem and a tax withholding problem that are significantly more expensive to remediate than they would have been to prevent.
If you are considering adding non-U.S. investors to an existing domestic offering, or designing a new fund that will accommodate international capital alongside U.S. investors, the review of both the Regulation S compliance framework and the FIRPTA and partnership withholding infrastructure with securities counsel and tax counsel is the appropriate starting point before any investor communication is sent.
Frequently Asked Questions
Can a non-U.S. investor invest directly in a domestic Rule 506(b) or 506(c) fund?
Yes, with conditions. Non-U.S. investors are not automatically excluded from Regulation D, but their admission requires independent satisfaction of Regulation S’s offshore transaction requirements: the transaction must be completed in an offshore transaction, the investor must be a non-U.S. person, and no directed selling efforts may be conducted in the United States in connection with their admission. Adding a Regulation S offshore tranche to the domestic offering addresses these requirements and provides a cleaner compliance structure than treating the non-U.S. admission solely under Regulation D.
What is the directed selling efforts prohibition under Regulation S and how does it affect fund marketing?
No marketing activity may be conducted in the United States in connection with the Regulation S portion of a fund offering. This includes publicly accessible websites, social media, webinars, and conference presentations that non-U.S. viewers could access and that describe the offering. Sponsors must maintain separation between domestic marketing content (directed at U.S. investors) and offshore-directed communications (designed for non-U.S. investors and not deployed through channels that reach U.S. audiences).
What is Section 1446(a) withholding and when does it apply?
Section 1446(a) requires a domestic partnership to withhold U.S. tax on each foreign partner’s allocable share of effectively connected taxable income, including income from U.S. real estate operations and gains from property dispositions. The withholding rate is 37% for non-corporate foreign partners or 21% for corporate foreign partners. Withholding is remitted in quarterly installments and reported annually on Form 8804 (Annual Return) and Form 8805 (Foreign Partner’s Information Statement). This obligation must be built into the fund’s administrative infrastructure before any non-U.S. investor is admitted.
What is Section 1446(f) withholding and who bears the obligation?
Section 1446(f), added by the Tax Cuts and Jobs Act for transfers after December 31, 2017, requires the buyer in a secondary purchase of a partnership interest from a foreign partner to withhold 10% of the amount realized by the foreign seller, when any portion of the gain would be effectively connected income. The obligation falls on the buyer, not the seller. The fund’s operating agreement must give the manager authority to require compliance with this withholding before registering any transfer from a non-U.S. partner.
When should a sponsor use a separate offshore parallel vehicle rather than adding a Regulation S tranche to the domestic fund?
A Regulation S offshore tranche within the domestic fund is efficient when the non-U.S. investor base is small and the tax profiles are straightforward. A separate offshore parallel vehicle becomes preferable when the volume of non-U.S. investors is large enough that their varying withholding rates, treaty positions, and reporting requirements would impose meaningful administrative complexity on the domestic fund, or when the non-U.S. investors require a corporate-taxed offshore entity for ECI blocking that a transparent domestic partnership cannot provide.
