FIRPTA Withholding for Foreign Sellers of a Tampa Bay Luxury Home: The 15% Rule, Form 8288-B, and How to Reduce the Hold

How does FIRPTA withholding work when a foreign seller closes on a Tampa Bay luxury home?

When a foreign person sells a U.S. real property interest, federal law (26 U.S.C. 1445) requires the buyer to withhold 15% of the gross sale price and remit it to the IRS using Form 8288, generally within 20 days of closing. Two reduced rates apply when the buyer intends to use the home as a residence — 10% on sales between $300,000 and $1 million, and 0% under $300,000 — but most Tampa Bay luxury closings exceed both thresholds, so 15% is the working number. A foreign seller who expects an actual tax liability lower than that 15% can apply for a Form 8288-B Withholding Certificate to reduce the hold, but the IRS now takes roughly 90 to 120 days to act on a complete application.

 

If you're a non-U.S. citizen selling a Tampa Bay luxury home — or a U.S. buyer purchasing one — the title company will hand over a FIRPTA Affidavit somewhere between contract and closing, and a wrong answer can stall the closing or pull six figures out of the seller's net at the table. FIRPTA was passed in 1980, but the version that affects most Tampa Bay luxury sales today is the post-2016 framework with a 15% headline rate, three residence-use tiers, and a withholding-certificate process that has stretched into a 90-to-120-day window.

Here's the practical version, in the order it actually shows up in a Tampa Bay closing.

The 15% rule, and the two ways the rate drops

FIRPTA withholding is a percentage of the gross sale price — the “amount realized” — not a percentage of the seller's gain. That distinction surprises a lot of foreign sellers. On a $2.5 million Channel District condo, a 15% withholding equals $375,000 wired to the IRS at closing, even if the seller's actual long-term federal capital gain is closer to $400,000 and the eventual federal tax liability closer to $80,000.

There are two reduced rates, both tied to the buyer's stated use of the property:

• 0% withholding when the buyer signs a personal-residence affidavit and the amount realized is $300,000 or less.
• 10% withholding when the buyer signs a personal-residence affidavit and the amount realized is between $300,000 and $1 million.
• 15% withholding in every other case — including all non-resident-use purchases, and all sales above $1 million regardless of buyer use.

Tampa Bay luxury closings generally clear $1 million, so 15% is the working rate. The 10% rate occasionally applies to a primary-residence buyer at the lower end of the Downtown St. Pete or Hyde Park condo market, but it never applies to investment-use buyers — and a buyer who signs a residence affidavit must mean it. The IRS revisits the affidavit on audit if the property is rented or flipped within the first two years after closing.

The buyer is the withholding agent — even when the title company handles it

Under 26 U.S.C. 1445, the legal withholding agent is the buyer, not the seller and not the title company. The buyer is liable for the tax if it isn't withheld and remitted, plus interest and penalties. That's why every Florida title company runs the FIRPTA Affidavit on every closing — the affidavit protects the buyer.

In practice, the title company acts as a “qualified substitute” under the FIRPTA regulations. The qualified substitute can collect a non-foreign affidavit from a U.S.-person seller, satisfy the buyer's good-faith reliance defense, and remove the withholding obligation entirely when the seller is in fact a U.S. person. When the seller is a foreign person, the qualified substitute usually administers the withholding — preparing Form 8288 and Form 8288-A, transmitting the 15% to the IRS, and providing the seller with a stamped copy of Form 8288-A as the receipt for the seller's eventual nonresident tax return.

Two things follow from that structure:

1. The FIRPTA conversation is a buyer-side risk question first. A buyer purchasing from a foreign seller without proper withholding can end up paying the 15% out of their own pocket if the seller has left the country.
2. Both the listing agent and the buyer's agent have skin in the game. Under the regulations, an agent who knows or should have known the seller's affidavit was false can lose the agent's good-faith defense, though agent liability is capped at the compensation earned on the transaction.

Form 8288-B and the 90-to-120-day timeline that drives every other decision

A foreign seller whose actual federal tax liability is lower than 15% of the sale price can apply for a Withholding Certificate using Form 8288-B. The certificate, if granted, authorizes withholding at a reduced amount — sometimes zero. Most Tampa Bay luxury sellers who held the home for more than a year and have realistic basis records (purchase price, improvement receipts, capitalized closing costs) qualify for a meaningful reduction.

The constraint is timing. The IRS publishes a target processing window of roughly 90 days after a complete application is received, but practitioner experience through 2026 has certificates routinely running 90 to 120 days — sometimes longer. Faster outcomes happen, but a foreign seller cannot count on one.

That timing forces three early decisions in the listing process:

• Apply for an ITIN (Individual Taxpayer Identification Number) if the seller doesn't already have one. The ITIN is a prerequisite for Form 8288-B, and the W-7 application itself can take six to eight weeks.
• Engage a U.S. CPA who handles cross-border real estate before the listing goes live, not after a contract is signed. The 8288-B narrative needs basis support, capital improvement receipts, and a defensible projection of gain.
• Set expectations on the closing date early. The 8288-B can be filed at any point before closing, but the IRS does not have to issue the certificate before the closing date. If the certificate is still pending at closing, the title company will withhold and hold the 15% in escrow until the IRS rules — generally up to 20 days after the IRS response.

If the certificate is granted before closing, the reduced amount (or zero) is what gets withheld. If the certificate is granted after closing but during the escrow hold, the title company refunds the difference to the seller and remits the reduced amount to the IRS. If the certificate is denied or never issued, the full 15% goes to the IRS, and the seller files a U.S. nonresident return (Form 1040-NR) the following spring to claim a refund of any over-withholding.

Treaty math, ITINs, and what the affidavit cannot do

A common misconception: a tax treaty between the U.S. and the seller's home country switches FIRPTA off. It does not. Treaties can reduce or eliminate the underlying federal tax liability — the Canada-U.S. treaty, for example, allows Canadian residents to credit U.S. tax paid against Canadian tax — but FIRPTA is a withholding mechanism, not a tax. The withholding sits on top of whatever final liability the treaty produces, and the seller still has to file a nonresident return to reconcile.

The non-foreign affidavit signed at closing only works for U.S. persons. A green-card holder, or a foreign individual who passes the substantial presence test for the calendar year of sale, is a U.S. person for FIRPTA purposes and can sign the affidavit. A nonresident alien — including most snowbird owners on B-2 visas who never spent enough U.S. days to trigger substantial presence — cannot.

For LLCs, partnerships, and trusts, the analysis is more layered. A single-member LLC owned by a foreign person is treated as a disregarded entity, and FIRPTA looks through to the foreign owner. Multi-member LLCs and partnerships have their own withholding rules under IRC 1446(f). Trusts depend on the trust's tax classification.

I've seen this layer create needless worry. On a South Tampa condo sale, my seller held title through an LLC and the question of withholding came up early — but the LLC was formed in the United States, and once its status was documented, no FIRPTA withholding applied at all. FIRPTA turns on the seller's tax status, not on assumptions the other side of the table makes about it.

The 2025 electronic-payment rule

Effective September 30, 2025, the IRS no longer accepts paper checks for FIRPTA payments. All Form 8288 remittances now move through EFTPS, the federal electronic payment system. Tampa Bay title companies updated their FIRPTA procedures around that date, but it's worth confirming with the closing agent that the EFTPS pathway is already in place — particularly for closings handled by smaller offices that were still adapting in late 2025.

Where this matters most in Tampa Bay

Foreign ownership concentrates in the same Tampa Bay luxury corridors year after year — the Davis Islands waterfront, Bayshore Beautiful, Channel District, Westshore Marina District, Snell Isle, Clearwater Beach, and the branded-condo buildings on Bayshore and in Downtown St. Pete. Many of those owners bought between 2018 and 2022 and are reaching natural exit timelines now. A clean FIRPTA process — ITIN already in place, CPA engaged at listing, Form 8288-B filed at listing or shortly after — protects the closing date and preserves the seller's net.

For a U.S. buyer purchasing from a foreign seller, the same early-process discipline matters in reverse. The title company's qualified-substitute role does most of the heavy lifting, but the buyer should confirm the affidavit chain in writing and review the Form 8288-A copy before leaving the closing table. That's the receipt the seller will eventually use to claim a refund, and it's the document that protects the buyer if the IRS later questions the withholding.

Frequently Asked Questions

Does FIRPTA apply when a U.S. citizen sells a Tampa Bay luxury home?

No. FIRPTA only applies when the seller is a foreign person — a nonresident alien, a foreign corporation, a foreign partnership, or certain foreign trusts. A U.S. citizen, a green-card holder, or a foreign individual who meets the substantial presence test for the year of sale can sign a non-foreign affidavit at closing and remove the withholding obligation entirely.

How long does it take the IRS to issue a Form 8288-B Withholding Certificate?

The IRS targets about 90 days from receipt of a complete application, but real-world processing through 2026 has been running 90 to 120 days. Faster outcomes happen, but a foreign seller and listing agent should plan for the longer window and start the application before — or alongside — the listing going live.

Who is technically responsible for FIRPTA withholding — the buyer, the seller, or the title company?

The legal withholding agent is the buyer. The title company normally acts as a qualified substitute that administers the withholding on the buyer's behalf, but if the withholding is missed, the buyer is the party the IRS pursues for the unpaid 15%, plus interest and penalties. The listing and buyer's agents can also lose their good-faith defenses if they knew the affidavit was false, with agent liability capped at the agent's compensation on the transaction.

Can a tax treaty reduce or eliminate FIRPTA withholding?

Treaties can reduce the underlying federal tax liability, but they do not switch the FIRPTA withholding mechanism off. A foreign seller relying on a treaty to lower the eventual tax bill still has to apply for a Form 8288-B Withholding Certificate to reduce the cash hold at closing, and still has to file a nonresident U.S. return to reconcile.

What happens if the Withholding Certificate is still pending on the closing date?

The closing proceeds, and the title company holds the full 15% in escrow rather than transmitting it to the IRS. Once the IRS rules on the application, the title company has up to 20 days to remit the certified amount and refund any difference to the seller. If the application is denied, the full 15% is remitted, and the seller files Form 1040-NR the following spring to claim any refund.

 

If you're a foreign owner planning to sell a Tampa Bay home — or a U.S. buyer making an offer on one — the FIRPTA conversation needs to happen before the contract is signed, not at the closing table. A direct conversation usually clears more up than another search.
