Can a Foreign Seller Lose Their FIRPTA Withholding? Yes.

Foreign sellers can lose substantial FIRPTA withholding through missed filings, administrative errors, and failure to claim available refunds.

Many foreign sellers assume that once FIRPTA withholding has been remitted to the IRS, the transaction is complete. Unfortunately, that assumption is not always correct.

In many transactions, the process begins with a fundamental misconception. Rather than first determining whether the seller qualifies for a withholding exemption, a reduced withholding certificate, or another lawful strategy to reduce the required withholding, the parties simply proceed with full statutory withholding. While that may ultimately prove appropriate, it is often accepted as the default without fully evaluating the seller's available options.

FIRPTA withholding is generally not the seller's final U.S. tax liability. It is a withholding—a prepayment toward whatever U.S. tax is ultimately determined to be due. Depending upon the seller's actual tax liability, some or even all of the withholding may ultimately be refundable.

Unfortunately, for some foreign sellers, the problems are only beginning.

As we will see, when sellers are not properly educated throughout the FIRPTA process, one oversight often leads to another. Those compounded failures can ultimately result in the seller losing their FIRPTA withholding entirely.

How Problems Compound

In my experience, which runs decades, difficult FIRPTA cases rarely result from a single mistake. More often, they are the result of a series of seemingly small oversights that compound over time.

The transaction closes. Full withholding is remitted. Everyone moves on.

The seller may never have been informed that a withholding exemption or reduced withholding certificate should first have been evaluated. An ITIN may not have been obtained before closing. Forms may contain administrative errors or omissions. IRS correspondence may be mailed to an outdated address or never reach the seller overseas. The withholding may not be properly associated with the seller's taxpayer account. No qualified U.S. representative may be monitoring the matter. Finally, the seller may never file the U.S. tax return required to claim any refund that may be due.

Standing alone, each of these issues may be correctable.

Together, they often create the difficult FIRPTA cases that surface months or even years after closing.

The Number One Reason Sellers Lose Their FIRPTA Withholding

The single most common reason foreign sellers lose their FIRPTA withholding is that they never file the required U.S. income tax return claiming any refund that may be due.

Many sellers mistakenly believe the withholding paid at closing was their final U.S. tax. Believing the matter has been completed, they never file the return needed to determine whether all or part of the withholding should be refunded.

The Internal Revenue Code establishes statutes of limitation governing refund claims. Generally, a refund claim must be filed within three years after filing the return or two years after the tax was paid, whichever provides the later deadline. If those deadlines expire, recovering excess withholding may become impossible or substantially more difficult, subject to limited exceptions.

By the time many sellers seek professional assistance, valuable time has already been lost.

The Financial Stakes

The financial consequences can be significant.

Consider the sale of a $1.5 million property. In many high-end real estate markets that attract foreign investment, this may represent only a fraction of the value of the properties being sold, making the potential financial loss substantially greater.

At the standard 15% withholding rate, $225,000 is remitted to the IRS at closing. If the property sells for $3 million, the withholding becomes $450,000. At $5 million, it increases to $750,000. Luxury properties in high-value markets can involve significantly larger withholding amounts.

In many instances, foreign sellers purchased these properties with cash. Because they mistakenly believe the FIRPTA withholding is the actual tax—not merely a withholding against the ultimate tax liability—they often lose sight of the practical need to file the required U.S. tax return and pursue a full or partial refund. The larger the withholding, the greater the potential financial loss.

As time passes, the situation often becomes increasingly difficult. Files may have been archived or destroyed. Personnel change. Records become harder to locate. Memories fade. Reconstructing the transaction becomes more expensive and time-consuming than addressing the issues when they first arose.

If sellers are unable to locate a firm experienced in difficult FIRPTA case resolution, the problem often remains unresolved or becomes even more difficult to correct.

Prevention Is Better Than Resolution

Most of these problems are preventable.

Proper FIRPTA planning begins before the transaction closes—not afterward.

Buyers, sellers, Realtors®, buyer's closing agents, seller's representatives, attorneys, and other transaction participants all benefit from understanding how FIRPTA actually works and why each document and filing matters.

What many view as routine FIRPTA paperwork at closing frequently determines whether the seller's withholding will later be properly credited, documented, and ultimately recoverable.

This is a classic example of being penny wise and pound foolish. A modest investment in qualified FIRPTA guidance before closing can often avoid years of unnecessary expense, delay, and uncertainty later.

Why Everyone Should Care

These issues do not always affect only the foreign seller.

When substantial withholding remains unrecovered, sellers naturally begin asking questions. They seek closing files, IRS filings, correspondence, and supporting documentation. Buyers, closing agents, real estate brokerages, attorneys, and other participants may find themselves responding to inquiries years after believing the transaction had been completed.

In some situations, foreign sellers retain U.S. legal counsel to evaluate whether legal remedies may exist based upon the specific facts and applicable law.

Comprehensive documentation, accurate filings, and experienced FIRPTA guidance from the outset help reduce the likelihood of these situations developing.

Difficult FIRPTA Case Resolution

Fortunately, not every difficult FIRPTA matter is beyond resolution.

Over the years, I have successfully assisted in recovering millions of dollars involving complex FIRPTA withholding matters complicated by administrative errors, delayed filings, IRS account issues, missing documentation, and other challenging circumstances.

These are not routine FIRPTA transactions. They fall within the specialized field of difficult FIRPTA case resolution.

FPG-USA specializes in all aspects of FIRPTA advisory, compliance, and difficult case resolution. We work with foreign sellers, attorneys, closing professionals, Realtors®, and other advisors to analyze complex FIRPTA matters, reconstruct transactions when necessary, identify the underlying issues, and help move stalled cases toward resolution.

Just as importantly, we believe the best difficult FIRPTA case is the one that never develops. Through education, careful planning, and proactive guidance before closing, many of the problems discussed in this article can be avoided altogether.

Our objective is not simply to help complete a FIRPTA transaction. It is to help ensure the seller's withholding is properly evaluated, planned, documented, protected, and ultimately brought to a successful conclusion.
