Under IRC §1445, the BUYER — not the seller, not the closing agent, not the title company — is the statutory withholding agent for FIRPTA. If the seller turns out to have been a foreign person and the withholding wasn't handled correctly at closing, the IRS will pursue the buyer personally for the 15% withholding, penalties up to 25%, and daily interest. “I didn't know” is not a defense.
The setup: a U.S. buyer closes on a $900,000 property. The closing goes smoothly. Title company prepares the documents, funds wire, deed records, buyer takes possession. Nobody at the closing table flags FIRPTA — either because the closing file didn't surface that the seller was foreign, or because the non-foreign affidavit wasn't carefully checked, or because the seller represented through an LLC that looked domestic.
Eighteen months later, the buyer receives IRS Notice CP15 or CP504 from the Ogden Service Center: "You failed to file Form 8288 and remit FIRPTA withholding on the sale of [property]. Amount due: $135,000 plus penalties and interest."
The math:
The IRS pursues this against the buyer because IRC §1445(a) makes the buyer the legally designated Withholding Agent. The seller is back in their home country. The title company isn't a party. The closing attorney already collected their fee and moved on. The buyer is the one who answers the notice.
FIRPTA — the Foreign Investment in Real Property Tax Act of 1980, codified at IRC §1445 — was specifically designed to put the burden on the buyer for a practical reason: the foreign seller doesn't stick around after closing. Once the wire hits the seller's account, they leave the country with the proceeds. The IRS has no jurisdiction to pursue collection abroad, so Congress built the enforcement mechanism around the party that DOES stay in the U.S.: the buyer.
The statute is mechanical:
The closing agent's responsibility ends with handling the mechanics. The buyer's liability never ends until the IRS confirms the obligation was met — which means stamped Form 8288-A copies returned by the IRS as proof.
For closings under $300,000 where the buyer intends to occupy the property as a personal residence, an additional protection exists: the §1445(b)(5) personal-residence exception eliminates withholding if the BUYER signs an affidavit committing to occupy the property as a residence for at least 50% of the days it's used in each of the first two 12-month periods after closing. Critically, this requires the BUYER's signed affidavit, not just a price under $300K.
Three paths exist depending on how recently the closing happened and whether the IRS has already issued a notice:
If FIRPTA was missed but it's still within the 20-day window from closing, the buyer can still file Form 8288 + 8288-A and remit the withholding on time. Penalties for filing on the 19th day are zero. This is the cheapest fix. Engage a FIRPTA specialist immediately and get the package mailed to IRS Ogden via tracked overnight before day 20.
Voluntary compliance — file Form 8288 + 8288-A late, remit the withholding, and pay the failure-to-deposit penalty (typically capped at 10% if the filing is voluntary and within 30 days of the deadline). Coming forward voluntarily is dramatically better than waiting for an IRS notice, both for the penalty cap and for the avoidance of the willful-failure §7202 exposure.
