FIRPTA Withholding: What Phoenix-Area Buyers Should Verify

What is FIRPTA withholding and who carries it?

FIRPTA is the federal law that makes the buyer, as transferee, the withholding agent when real property is sold by a foreign person. Withholding is not the final tax on the seller's gain; it is an advance remittance against the seller's U.S. tax obligation, and the seller's actual tax is settled separately with the IRS.

The critical fact for buyers: the buyer is personally liable if withholding is not done. That is why the documents, not the vibes, decide the process. A title company or closing agent can handle the mechanics, but the statutory obligation and its liability rest with the buyer unless the transaction is documented correctly.

What are the withholding rates and the exceptions?

The residence tests are real requirements: the buyer or a family member must have definite plans to reside at the property for at least 50% of the time it is used during each of the first two 12-month periods after the transfer. Meeting the price threshold alone is not enough for the exception.

How does the seller's status get documented?

Withholding is avoided when the seller provides a certification of non-foreign status: typically a W-9 or an affidavit stating the seller is a U.S. person, dated no more than 30 days before the transfer. If the seller is foreign, or cannot provide that certification, FIRPTA withholding applies unless the seller obtains an IRS withholding certificate.

One rule matters enormously in practice: do not infer a seller's status from nationality, ethnicity, language, or appearance. A foreign-sounding name tells you nothing about tax status, and a U.S. citizen can hold foreign residence or appear on foreign documents. The certification, not the impression, is what the law runs on.

What are the forms and deadlines?

• Form 8288 reports the disposition and remits the withheld tax; it must be filed and paid within 20 days of the transfer.
• Form 8288-A is the statement furnished to each foreign seller documenting the amount withheld.
• Form 8288-B is the foreign seller's application for a withholding certificate to reduce or eliminate withholding before closing.

A withholding certificate application includes the seller's estimated gain, basis, and tax computation, and the IRS normally acts on a complete application within roughly 90 days, so the application must start well before closing. If a certificate eliminates withholding, no Form 8288 is needed; if it reduces withholding, the buyer still files and remits the reduced amount, and if the IRS decision is pending at closing, the buyer withholds and files within the required window after the decision is mailed. The current IRS pages for FIRPTA withholding, exceptions, and Forms 8288 and 8288-B are the authoritative references.

Why doesn't an escrow holdback automatically fix this?

An escrow holdback is a practical arrangement for holding funds until an event or condition resolves. FIRPTA is a statutory withholding regime: the buyer must ensure the tax is withheld, reported on Form 8288, and remitted to the IRS within 20 days of the transfer. A holdback that simply parks money at closing without the required filing and payment does not satisfy the statute, and the buyer's personal liability remains.

If you are told a holdback covers FIRPTA, ask to see how the escrow instructions implement the statutory process: who files Form 8288, who remits the tax, and by what date. If the instructions only retain funds without the IRS filing, that is a gap to close with your title and tax professionals.

What should a Phoenix-area buyer verify before closing?

• Request the seller's certification of non-foreign status (W-9 or affidavit), dated within 30 days of transfer, early in the transaction.
• If the seller is foreign, confirm who files Forms 8288 and 8288-A, and that withholding is paid within 20 days of the transfer.
• Ask whether the property qualifies as a residence for the reduced or eliminated rates, and document the buyer's occupancy plans.
• Confirm with the title company or closing agent that escrow instructions implement the FIRPTA process, not just a holdback.
• If the seller plans to apply for a withholding certificate, verify the Form 8288-B timeline and who tracks the IRS decision and the related filing deadlines.
• Consult a qualified tax professional and legal counsel for the specific facts of your transaction; this guide is education, not tax or legal advice.
