FIRPTA Withholding in Cross-Border M&A: Rules for Foreign Sellers of US Real Property

The Foreign Investment in Real Property Tax Act of 1980 established a withholding regime that operates at the intersection of real property ownership, corporate structure, and cross-border M&A. FIRPTA's core rule is straightforward: when a foreign person disposes of a US real property interest, the buyer is required to withhold 15% of the amount realized and remit it to the IRS as a prepayment against the foreign seller's US tax liability on the gain. The complexity lies in determining what counts as a US real property interest, who counts as a foreign person, when withholding is reduced or eliminated, and how FIRPTA interacts with corporate transaction structures in M&A.

This sub-article is part of the Cross-Border M&A: A Legal Guide. It addresses the complete FIRPTA framework as applied to foreign sellers in cross-border M&A transactions: the statutory foundation under IRC Sections 897 and 1445, the USRPHC test and five-year look-back rule, stock vs. asset sale treatment, withholding rates and exemptions, the Form 8288 and 8288-B compliance process, non-recognition transactions, treaty elections, buyer indemnification obligations, seller planning with corporate blocker structures, the interaction with Section 338(h)(10) elections, IRS audit risk, and state withholding overlay regimes. For the CFIUS national security review framework applicable to foreign acquisitions of US businesses, see the companion article on CFIUS review in cross-border M&A.

Acquisition Stars represents buyers and sellers in cross-border M&A transactions involving US real property. The framework below describes FIRPTA as a general matter. Nothing in this article constitutes legal or tax advice for any specific transaction; each situation requires individualized analysis by qualified counsel.

The FIRPTA Statutory Framework: IRC Sections 897 and 1445

FIRPTA operates through two paired Code sections. IRC Section 897 is the substantive provision: it establishes that gain or loss of a nonresident alien individual or foreign corporation from the disposition of a US real property interest is treated as income effectively connected with the conduct of a trade or business in the United States and is therefore subject to US income taxation. Before FIRPTA, foreign persons who disposed of US real property could generally avoid US taxation on the gain because, absent effectively connected income status, only US-source income of foreign persons was taxable in the United States, and capital gain from property sales was not automatically US-source income for non-US-resident sellers. Section 897 eliminated this gap by deeming USRPI dispositions to produce effectively connected income subject to US tax at the applicable rates.

IRC Section 1445 is the withholding mechanism. It requires the buyer in any qualifying USRPI disposition to withhold and remit to the IRS an amount equal to 15% of the amount realized by the foreign seller on the disposition. The withholding is not the tax itself but rather an advance collection mechanism: the 15% withheld is a prepayment applied against the foreign seller's actual US tax liability when the seller files a US income tax return for the year of the disposition. If the foreign seller's actual tax liability is less than the amount withheld, the seller is entitled to a refund. If the actual liability exceeds the amount withheld, the seller must pay the balance when filing. The buyer who fails to withhold the required amount is liable to the IRS for that amount plus interest and penalties, regardless of whether the seller ultimately pays the underlying tax.

The amount realized for FIRPTA withholding purposes is the total consideration the foreign seller receives for the USRPI, including cash, the fair market value of any property received, and the amount of any liabilities assumed by the buyer or relieved from the seller. In an M&A context, this includes not only the stated purchase price but also any earnout or contingent consideration, any debt assumed or retired at closing, and any seller financing provided by the buyer. The broad definition of amount realized means that the 15% withholding base in a leveraged transaction can significantly exceed the cash the seller receives at close.

Defining US Real Property Interests: The USRPI Categories

The concept of a US real property interest (USRPI) encompasses several categories of property and property-related rights that are subject to FIRPTA. The most obvious category is direct ownership of US real property: land and improvements to land located in the United States, including buildings, permanent structures, and natural resources such as minerals, timber, and water rights that are part of the real property. Growing crops and timber are generally included; detached personal property is generally not.

The second and critically important category for M&A purposes is an interest in a domestic corporation that is a USRPHC. The stock of a USRPHC is itself a USRPI, meaning that a foreign seller who disposes of stock in a domestic corporation that qualifies as a USRPHC is subject to FIRPTA withholding on the full amount realized from the stock sale, even though the seller is disposing of corporate equity rather than real property directly. This extension of FIRPTA to corporate stock is the reason that FIRPTA analysis must be conducted in every M&A transaction involving a foreign seller and a domestic corporate target, not only in transactions where real estate is obviously the subject matter.

The third category includes direct or indirect rights to receive, extract, or use real property or natural resources in the United States, such as mineral royalty interests, timber rights, and water rights that are separately held rather than bundled with land ownership. The fourth category includes certain leasehold interests with characteristics that make them more analogous to ownership than to pure rental arrangements. For most M&A transactions involving operating businesses, the first two categories - direct real property and USRPHC stock - are the primary analytical concerns. The other categories are more relevant to transactions specifically targeting natural resource or land rights.

The USRPHC Test: 50% Asset Test and the Five-Year Look-Back Rule

A domestic corporation is a USRPHC if the fair market value of its US real property interests equals or exceeds 50% of the sum of (1) the fair market value of its US real property interests, (2) the fair market value of its interests in real property located outside the United States, and (3) the fair market value of any other assets used or held for use in a trade or business. The 50% test is applied on a fair market value basis using the aggregate value of the corporation's assets, not their book or tax basis. Assets used or held for use in a trade or business is a defined term that includes business assets but excludes passive investment assets not connected to the corporation's trade or business.

The look-back rule extends USRPHC status to any corporation that was a USRPHC at any point during the five-year period ending on the date of the stock disposition. This means that a corporation that sold all of its US real property three years before an M&A transaction and no longer holds any real property may still be a USRPHC for purposes of a foreign seller's stock sale if it met the 50% asset test within the five-year look-back window. The look-back rule creates a persistent FIRPTA issue for operating companies that have undergone significant asset restructuring, sold off real estate in recent years, or converted from real-estate-heavy to asset-light business models. M&A due diligence for cross-border transactions should include a historical USRPHC analysis covering the prior five fiscal years, not just the current year's balance sheet.

A corporation can establish that it is not a USRPHC through a USRPHC determination that is issued by the corporation itself by providing a certificate to buyers stating that interests in the corporation are not USRPIs. However, the corporation is liable for any FIRPTA tax that is not collected if the certificate is incorrect, and the buyer cannot rely on a false USRPHC certificate to avoid FIRPTA liability. Before the seller provides a USRPHC certificate in a cross-border M&A transaction, the corporation must actually perform the five-year look-back analysis and confirm its USRPHC status on each year's testing date with reference to documented asset valuations.

Stock Sale vs. Asset Sale: FIRPTA Treatment and Withholding Base Differences

The treatment of FIRPTA withholding differs materially between stock sales and asset sales, and the choice of transaction structure by the parties carries significant FIRPTA implications that must be considered alongside the other tax and legal factors that drive the stock vs. asset decision.

In a stock sale by a foreign seller of a domestic corporation that is a USRPHC, FIRPTA withholding applies to the full amount realized on the stock sale - the entire purchase price for the shares - because the stock of a USRPHC is a USRPI in its entirety. There is no allocation of the stock sale price between real property and non-real-property components: the stock is treated as a USRPI as a whole, and the 15% withholding is applied to the full consideration. This can produce a withholding obligation that significantly exceeds what would be withheld in an asset sale where real property represents only a fraction of total asset value, because in the asset sale the withholding base is limited to the consideration allocated to the real property assets. For a comprehensive review of how deal structure affects tax outcomes beyond FIRPTA, the deal structure guide addresses the full scope of buyer and seller tax considerations.

In an asset sale, FIRPTA withholding applies to each USRPI transferred as a separate item. The buyer must withhold 15% of the amount of the purchase price allocated to each USRPI as determined by the Section 1060 purchase price allocation. If the parties agree in the purchase agreement that $3 million of a $10 million asset purchase price is allocated to real property and the remainder to equipment, accounts receivable, goodwill, and other non-real-property assets, then FIRPTA withholding is 15% of $3 million ($450,000), not 15% of $10 million ($1.5 million). The purchase price allocation therefore has a direct impact on the FIRPTA withholding calculation, and both parties should be aware of this when negotiating the allocation schedule.

The foreign seller's overall US tax liability on the gain is determined separately from the withholding base. In a stock sale, the gain is the difference between the amount realized and the foreign seller's adjusted basis in the stock. In an asset sale, the seller recognizes gain or loss on each asset separately, and the FIRPTA-taxable portion is the gain on the real property assets. The withholding at close is an advance payment regardless of how the seller's actual tax liability ultimately calculates; the reconciliation occurs when the seller files a US tax return.

The 15% Default Withholding Rate and Available Exemptions

The default FIRPTA withholding rate is 15% of the amount realized by the foreign seller on the disposition of a USRPI. This rate was increased from 10% to 15% by the Protecting Americans from Tax Hikes Act of 2015 (PATH Act) for transactions closing after February 16, 2016. A reduced 10% rate continues to apply in limited circumstances, specifically when the property being transferred is acquired by the buyer for use as a residence and the amount realized does not exceed $1,000,000. For commercial real property and for stock sales of USRPHCs, the 15% rate applies without exception unless an exemption or certificate reduces the obligation.

The most significant exemptions and reductions from the 15% withholding obligation are: a non-foreign person certificate, in which the seller certifies under penalty of perjury that it is not a foreign person (this exemption eliminates withholding entirely when the seller is in fact a US person or domestic entity); a USRPHC non-recognition certificate, in which the domestic corporation certifies it is not and has not been a USRPHC during the relevant look-back period; a qualifying statement from the IRS establishing that no withholding or reduced withholding is required; a withholding certificate issued by the IRS in response to a Form 8288-B application establishing the maximum withholding based on the seller's actual US tax liability; publicly traded corporation stock (when the USRPHC's stock is regularly traded on an established securities market and the disposing foreign person held 5% or less of the class of stock during the five-year look-back period); non-recognition treatment for certain reorganizations, contributions, and liquidations; and a general exemption for the disposition of an interest in a domestic corporation that is furnishing a domestic corporation interest statement certifying the non-USRPHC status.

Each exemption requires specific documentation that must be in the buyer's possession at or before close. The buyer cannot withhold a reduced amount or zero based on verbal assurances from the seller. The documentation requirements are prescribed by IRS regulations and must be strictly followed. M&A counsel should identify which, if any, exemption applies and ensure that the required documentation is part of the closing deliverable checklist well before the closing date.

Non-Recognition Transactions: Reorganizations, 351 Contributions, and Liquidations

FIRPTA's withholding and taxation rules are modified for certain non-recognition transactions - transactions in which the seller's gain is not recognized for US federal income tax purposes by operation of a specific Code provision. When a non-recognition provision applies to the full gain, FIRPTA withholding is reduced to zero. When a non-recognition provision applies to only a portion of the gain (because boot or other recognized consideration is involved), withholding is reduced to the amount of tax attributable to the recognized portion.

Section 368 corporate reorganizations that involve USRPIs must be analyzed carefully for FIRPTA purposes. A Type A merger in which a foreign corporation holds a USRPHC and receives stock of the acquiring domestic corporation in a tax-free exchange under Section 368(a)(1)(A) may qualify for non-recognition treatment for the FIRPTA-taxable gain, provided that the stock received is itself a USRPI in the hands of the foreign corporation. The exchange of one USRPI for another USRPI is treated as not triggering FIRPTA recognition, because the foreign person continues to hold a USRPI after the exchange. However, to the extent the reorganization involves any boot (cash or non-USRPI consideration), the boot portion is recognized and FIRPTA withholding applies to the tax attributable to the recognized amount.

Section 351 contributions in which a foreign person contributes a USRPI to a domestic corporation in exchange for stock may qualify for FIRPTA non-recognition if the stock received is itself a USRPI (stock of a USRPHC). This non-recognition rule does not apply if the USRPI is contributed to a foreign corporation, which would remove the property from the FIRPTA system without substituting a new USRPI. Liquidations of USRPHCs - distributions of USRPI assets to foreign shareholders in complete liquidation of the corporation - are treated as dispositions subject to FIRPTA taxation at the shareholder level. The corporation distributing the property must withhold on the distribution at the applicable rate. The interaction between the corporate-level tax on the distribution and the shareholder-level FIRPTA tax on the deemed disposition requires careful analysis for cross-border liquidation transactions.

FIRPTA Compliance at Close: Forms 8288, 8288-A, and 8288-B

The mechanics of FIRPTA compliance at close center on three IRS forms that each serve a distinct function in the withholding and reporting system. Understanding the purpose, timing, and filing requirements of each form is a practical prerequisite to managing FIRPTA compliance in an M&A transaction.

Form 8288 (US Withholding Tax Return for Dispositions by Foreign Persons of US Real Property Interests) is the primary remittance form. The buyer completes Form 8288, attaches a copy of Form 8288-A for each disposition (see below), and submits the form together with the withheld funds to the IRS. The form and remittance must be filed within 20 calendar days of the closing date. The 20-day deadline is absolute: there is no grace period or extension available. Buyers who close a transaction without a FIRPTA withholding plan in place risk missing the 20-day deadline, triggering interest and penalties on the full withheld amount. Closing counsel should calendar the 20-day deadline immediately upon closing confirmation and ensure the closing agent or escrow has clear wire transfer instructions for the IRS remittance.

Form 8288-A (Statement of Withholding on Dispositions by Foreign Persons of US Real Property Interests) is the per-transaction information return that accompanies Form 8288. The buyer prepares two copies: one is filed with the IRS (attached to Form 8288), and the second is provided to the foreign seller to use as a credit document when filing the seller's US income tax return for the year. The IRS stamps the seller's copy after processing and returns it, which the seller must retain to support the credit claim on the annual return. The IRS's processing and return of the stamped copy can take several months, which creates a timing gap between the seller's need for the document and its availability.

Form 8288-B (Application for Withholding Certificate for Dispositions by Foreign Persons of US Real Property Interests) is the application through which the foreign seller or buyer requests that the IRS reduce the withholding obligation to reflect the seller's actual US tax liability rather than the full 15% of amount realized. The form is filed with the IRS before or simultaneously with the closing. When a Form 8288-B application is pending at the time of closing, the parties typically enter into a withholding certificate escrow arrangement: the buyer withholds the full 15% (or other applicable amount) and places those funds in an escrow account rather than remitting them to the IRS immediately, pending the IRS's response to the 8288-B application. When the IRS issues the withholding certificate specifying the approved reduced withholding amount, the escrow funds are split: the reduced withholding amount is remitted to the IRS and the remainder is released to the seller.

Buyer Liability for Under-Withholding and Indemnification Mechanics

The FIRPTA withholding obligation belongs to the buyer. If the buyer fails to withhold the correct amount from the consideration paid to the foreign seller, the IRS can collect the full amount of the under-withholding from the buyer directly, with interest and penalties from the date the withholding was due. This creates a direct financial liability for the buyer that is independent of any obligation the seller may have to pay the underlying FIRPTA tax. The buyer cannot shift this liability to the seller by pointing to the seller's obligation to file a US tax return; the IRS's enforcement path against the withholding agent is a separate legal track from its enforcement of the underlying tax against the seller.

Given this buyer liability, M&A purchase agreements in cross-border transactions should address the allocation of FIRPTA risk explicitly. Standard provisions include: a representation by the seller as to whether it is a foreign person for FIRPTA purposes; a covenant by the seller to provide, at or before close, all documentation required for any applicable withholding exemption; a buyer indemnity provision under which the seller indemnifies the buyer for any FIRPTA liability, penalties, and interest that result from the seller's failure to provide accurate FIRPTA documentation or from the seller's incorrect representation of its foreign person status; and an obligation on the seller to cooperate with the Form 8288-B process if the parties are applying for a reduced withholding certificate.

The indemnity structure is particularly important when the FIRPTA analysis involves USRPHC determinations, because the buyer is relying on the target company's representation that it is not a USRPHC (or is one) and the underlying analysis depends on asset valuations and historical records that the buyer cannot independently verify with certainty before close. If the seller provides a USRPHC certificate that turns out to be inaccurate, the IRS can impose withholding liability on the buyer. The buyer's contractual indemnity from the seller is its protection against this outcome, and the indemnity should survive closing for at least the period during which the IRS audit risk for the year of closing remains open (generally three years from the filing of the relevant US tax returns, or six years in cases of substantial understatement).

Treaty Elections and Tax Rate Reduction for Foreign Sellers

US income tax treaties with foreign countries generally do not override FIRPTA's withholding mechanism, but they may affect the foreign seller's ultimate US tax liability on the gain and in some cases support an application for a reduced withholding certificate under Form 8288-B.

FIRPTA contains a statutory override of treaty non-discrimination and treaty capital gains provisions to the extent those provisions would prevent imposition of FIRPTA taxation on USRPI dispositions. Congress included this override specifically to prevent foreign sellers from using treaty benefits to circumvent FIRPTA's reach. The practical effect is that most treaty capital gains exemptions or reduced rates that a foreign seller might rely on for other US-source income do not apply to USRPI dispositions.

However, where a treaty provides a specific reduced rate for capital gains from real property dispositions (as opposed to a general capital gains exemption), and the IRS has not explicitly overridden that specific provision in its treaty technical explanations or published guidance, a foreign seller may be able to argue for application of the reduced treaty rate to the FIRPTA-taxable gain. This argument must be presented through a Form 8288-B application, in which the seller proposes a reduced withholding amount based on the treaty rate applied to the net gain rather than 15% of the gross amount realized. The IRS will evaluate the treaty claim and either accept it (issuing a certificate for reduced withholding based on the treaty rate) or decline it (requiring withholding at the full statutory rate). Given the uncertainty in treaty analysis for FIRPTA purposes, foreign sellers from countries with real property gain provisions in their US treaty should raise this with their US tax counsel before assuming a treaty benefit is available.

Seller Tax Planning: Corporate Blocker Structures and Pre-Transaction Restructuring

Foreign sellers who anticipate a FIRPTA exposure may engage in pre-transaction planning to reduce or restructure the FIRPTA tax liability before the M&A transaction closes. Planning options range from relatively straightforward basis adjustment strategies to more complex structural approaches that change the form of the disposition.

A corporate blocker structure, sometimes called a treaty shopping structure in international tax parlance (though the legitimacy of such structures requires careful analysis under current anti-abuse rules), involves the interposition of a domestic C corporation between the foreign seller and the USRPI. If a foreign person contributes a USRPI to a new domestic corporation in a tax-free Section 351 exchange, the stock of that domestic corporation is itself a USRPI (assuming the corporation immediately becomes a USRPHC). However, the domestic corporation now holds the property at a cost basis equal to the contribution date fair market value, and subsequent appreciation of the property accrues inside the domestic corporation. If the domestic corporation is held long enough and the operating facts support it, the corporation may be able to generate deductions (depreciation, business expenses) that reduce its net gain exposure, and the foreign seller's gain on a future sale of the domestic corporation stock may be lower than the gain that would have been recognized on a direct real property disposition.

A more aggressive planning technique involves using the corporate blocker structure in combination with a treaty between the United States and the jurisdiction of incorporation of an intermediate holding company. Some older US tax treaties provided capital gains exemptions that, when combined with a domestic blocker corporation owned by a treaty-country holding company, could reduce the effective FIRPTA tax rate. The IRS has published significant guidance and regulations limiting these structures under FIRPTA's treaty override provisions and the limitation on benefits provisions included in modern US tax treaties. Any pre-transaction structure designed to reduce FIRPTA exposure should be reviewed by US international tax counsel for compliance with current regulations, treaty provisions, and the FIRPTA treaty override statute before implementation.

A straightforward basis increase strategy involves the foreign seller making additional capital contributions to the property entity before the sale, increasing the adjusted basis and thereby reducing the gain subject to FIRPTA tax. Depreciation deductions taken historically reduce the adjusted basis, so sellers who have maximized depreciation deductions will have lower basis and higher FIRPTA exposure. Cost segregation studies conducted before the sale cannot retroactively change past depreciation but can affect the current-year deduction calculation and the basis allocated to components of the property.

Section 338(h)(10) Elections and FIRPTA: Interaction in M&A Transactions

A Section 338(h)(10) election is a mechanism that allows the parties in a stock acquisition to treat the transaction as an asset purchase for US federal income tax purposes. The buyer acquires stock, but both buyer and seller agree to treat the acquisition as if the target company sold all of its assets to the buyer and then liquidated into the seller. This election allows the buyer to obtain a stepped-up tax basis in the target's assets (which the buyer values because it produces larger future depreciation deductions) while the seller reports the transaction as an asset sale rather than a stock sale.

The interaction between a Section 338(h)(10) election and FIRPTA in a cross-border transaction requires careful analysis. When a 338(h)(10) election is made in a transaction involving a foreign seller and a USRPHC target, the transaction is recharacterized as an asset sale, which means FIRPTA withholding applies to the consideration allocated to real property assets rather than to the full stock consideration. For a target company whose real property represents a fraction of total enterprise value, this recharacterization can materially reduce the FIRPTA withholding base. From the buyer's perspective, the 338(h)(10) election also produces a stepped-up basis in the real property, which generates future depreciation deductions that may offset future taxable income.

However, the 338(h)(10) election is only available in limited circumstances: the target must be an S corporation or a member of a consolidated group (i.e., an 80% or more owned subsidiary of a domestic parent), and the buyer must be a domestic corporation or an S corporation. A foreign buyer cannot make a 338(h)(10) election. For cross-border transactions where the buyer is a foreign acquirer and the seller is a US parent selling a domestic subsidiary, the target may qualify for 338(h)(10), but the buyer must be a domestic entity. The availability of the election thus depends on the specific ownership and acquisition structure. For guidance on how these structural elections interact with the broader deal structure analysis, see the deal structure guide.

IRS Audit Risk, State Withholding Overlays, and FIRPTA Closing Checklist

FIRPTA transactions carry meaningful IRS audit risk at the buyer level, because the IRS can identify cross-border real property transactions through deed recording and state transfer tax filings and then verify whether the corresponding Forms 8288 and 8288-A were filed and whether the withholding was correct. A buyer who fails to file Form 8288, who fails to withhold, or who withholds a reduced amount without an IRS-issued withholding certificate may receive an IRS notice or examination years after the transaction closed. The statute of limitations for IRS assessment of withholding deficiencies under FIRPTA is generally three years from the date the return was filed (or would have been due if not filed), with extended periods for substantial understatements or fraud.

State withholding regimes impose additional compliance obligations that are entirely separate from the federal FIRPTA process. California requires buyers to withhold 3.33% of the total sales price of California real property sold by a non-resident seller (whether the seller is a US resident from another state or a foreign person), remitting to the California Franchise Tax Board on its own schedule. California non-resident sellers can apply to the FTB for a reduced withholding certificate (analogous to the federal Form 8288-B process) using Form 593 and Form 593-C. Hawaii requires withholding of 7.25% for non-resident individuals and 4% for corporations and other entities on Hawaii real property dispositions, remitted to the Hawaii Department of Taxation. Maryland, Colorado, and several other states have their own real property transfer withholding requirements for non-resident sellers. Buyers and their closing counsel must research the applicable state withholding requirements for every state in which the target holds real property.

A practical FIRPTA closing checklist for M&A counsel includes: early-stage identification of whether the seller is a foreign person for FIRPTA purposes; USRPHC analysis covering the full five-year look-back period; assessment of which withholding exemption, if any, applies and what documentation is required; determination of whether the parties will pursue a Form 8288-B reduced withholding application and, if so, filing well before close; drafting of FIRPTA representations, covenants, and indemnification provisions in the purchase agreement; coordination of the FIRPTA analysis with the Section 1060 purchase price allocation to ensure the withholding base is correctly calculated; preparation of Forms 8288 and 8288-A for the closing agent or buyer; establishment of a 20-day post-close remittance calendar entry; identification and analysis of applicable state withholding obligations; and retention of all FIRPTA documentation in the deal file for the full statutory period. For cross-border transactions involving regulated industries or significant real estate assets, FIRPTA compliance is one component of a multi-regulatory framework that may include CFIUS review and sector-specific approvals. The M&A transaction services overview at Acquisition Stars addresses how these regulatory frameworks are managed in complex cross-border deals.
