If you are a foreign or nonresident seller of California real estate, expect your buyer to withhold 15% of the sales price at closing under FIRPTA unless a residence exception or an approved withholding certificate reduces that amount. Your first move should be confirming your foreign-person status with your escrow officer and starting an ITIN application immediately if you don’t have a Social Security number. California adds its own withholding through Form 593, so ask escrow early which filings they will handle on your behalf.
TL;DR:
- Sellers should start the FIRPTA process at least 30 to 90 days before closing by applying for an ITIN and submitting a withholding certificate to avoid excess withholding.
- Minimum federal withholding is 15% of the sales price, but exceptions for primary residences and sales under $300,000 can reduce or eliminate that amount.
- California’s state withholding via Form 593 stacks with FIRPTA, which escrow companies process simultaneously, adding potential withholding from both authorities.
- Failure to comply with FIRPTA can lead to buyer liability, penalties, and extended delays, especially if documentation or applications are submitted late.
- Selling via installment payments complicates withholding, requiring early planning and possibly IRS approval of adjusted withholding schedules to avoid cash flow issues.

What Is FIRPTA and Who Does It Apply To?
The Foreign Investment in Real Property Tax Act exists to make sure the IRS collects tax on real estate gains earned by sellers who might otherwise leave the country before filing a return. Congress built FIRPTA around a simple problem: once a nonresident closes escrow and leaves the country, chasing down capital gains tax becomes far harder. Withholding at the closing table solves that collection problem before it starts.
The law defines “foreign person” broadly. It covers nonresident aliens, foreign corporations, foreign partnerships, foreign trusts, and foreign estates. Resident aliens, despite the name, are generally treated as U.S. persons for FIRPTA purposes and fall outside the withholding requirement.
Ownership structure creates some of the trickiest edge cases:
- Mixed marriages: If a foreign national co-owns a Cupertino or Sunnyvale property with a U.S. citizen spouse, withholding typically applies only to the foreign spouse’s ownership share, not the entire sale.
- Trust-owned property: A foreign trust holding title triggers FIRPTA even if a U.S. person manages daily affairs.
- Corporate ownership: Foreign corporations selling U.S. real property face withholding rules, and Congressional Research Service guidance notes special provisions apply to REITs and entities meeting certain ownership thresholds.
The next sections cover exact rates, exceptions, and the forms your buyer must file.
What Are the FIRPTA Withholding Rates and Exceptions?
Standard FIRPTA withholding runs at 15% of the “amount realized”, which is essentially your gross sales price, not your profit. That distinction trips up a lot of sellers who assume withholding tracks their actual gain. It doesn’t. For example, a million-dollar sale triggers withholding calculated on the total sales price regardless of the original purchase price.
Residence Exception Thresholds: No withholding applies when the buyer intends to use the property as a primary residence and the sales price is $300,000 or less. A reduced 10% rate applies for owner-occupied purchases priced above $300,000 but not exceeding $1,000,000, provided the buyer signs an affidavit confirming residence intent.
Because withholding is calculated on gross proceeds rather than net gain, the amount held back frequently exceeds what you actually owe the IRS. Sellers who overpay through withholding recover the difference by filing a U.S. tax return the following year and claiming a refund. It’s an advance payment against tax liability, not a final bill.
How Does the Buyer Handle FIRPTA Withholding Paperwork?
Under FIRPTA, the buyer, not the seller, carries the legal burden of withholding and remitting funds to the IRS. Here’s how that process typically unfolds:
- The buyer withholds funds at closing. Escrow calculates the required percentage based on the amount realized and holds it back from proceeds otherwise due to you.
- The buyer files Form 8288 with the IRS within 20 days of closing. This form transmits the withheld tax along with Form 8288-A, which reports the transaction details.
- You receive a stamped copy of Form 8288-A from the IRS. This document proves the withholding occurred and becomes essential when you file your U.S. tax return to claim credit or a refund.
If a buyer fails to withhold when required, the IRS can hold that buyer personally liable for the tax, plus penalties and interest. That liability exposure is exactly why title and escrow companies in Santa Clara County treat FIRPTA compliance seriously. They will request a completed affidavit or certification from you confirming residency status before closing, and they build the 20-day filing deadline into their post-closing checklist automatically.
How Can Sellers Reduce or Avoid FIRPTA Withholding?
You have real options here, and starting early makes all the difference. The single most useful tool is Form 8288-B, an application for a withholding certificate that asks the IRS to approve reduced or eliminated withholding based on your actual expected tax liability rather than the flat gross-price formula.
- Form 8288-B (withholding certificate): Approval can drop withholding from 15% of gross price down to a figure matching your real tax exposure, sometimes close to zero if you have minimal gain or a loss.
- Form W-7 (ITIN application): Sellers without a Social Security number need an Individual Taxpayer Identification Number to file Form 8288-B or a later tax return. Filing W-7 alongside 8288-B in the same package can speed processing.
- Non-foreign affidavit: If you’re actually a U.S. person despite an ambiguous name or address, signing an affidavit certifying non-foreign status avoids withholding entirely, provided the buyer accepts it in good faith.
Pro Tip: Don’t wait until you’re in escrow to think about your ITIN. Processing a Form 8288-B application through the IRS commonly takes several weeks, so start the paperwork 30 to 90 days before your anticipated closing date. If timing doesn’t allow for approval before closing, withholding will occur and you simply recover any excess later by filing a U.S. tax return.
How Does California State Withholding Interact With FIRPTA?
California runs its own withholding system separate from the federal FIRPTA requirement, and the Franchise Tax Board’s real estate withholding rules apply through Form 593. Escrow companies across Santa Clara County handle both filings side by side on most transactions involving a foreign or out-of-state seller.
- Federal and state withholding often stack. A foreign seller in Milpitas or San Jose may see both the FIRPTA amount and a separate California withholding percentage deducted from proceeds at the same closing.
- Escrow typically manages both filings. Title companies experienced with international sellers will prepare Form 8288/8288-A for the IRS and Form 593 for the FTB without requiring you to coordinate two separate processes yourself.
- Confirm the division of labor early. Ask your escrow officer directly which forms they file, which ones require your signature, and what documentation they need from you before the closing date locks in.
What Penalties Apply for FIRPTA Non-Compliance?
Non-compliance carries real financial teeth, and the exposure lands differently depending on whether you’re the buyer or the seller. Buyers who fail to withhold when required become personally liable for the tax that should have been collected, along with penalties and interest that accrue from the original filing deadline. That liability structure is precisely why escrow and title companies push hard on FIRPTA documentation before releasing any funds.
For sellers, the risk looks different. Providing a false non-foreign affidavit to avoid withholding, or misrepresenting residency status to qualify for a lower rate, exposes you to accuracy-related penalties and potential fraud consequences well beyond the withholding amount itself. The IRS treats sworn certifications seriously, and a buyer relying in good faith on a false affidavit shifts significant risk back onto the seller who signed it.
Late filing of Form 8288 by the buyer also triggers standard IRS late-filing and late-payment penalties, calculated as a percentage of the unpaid amount per month, plus interest that compounds until the balance is resolved. Because the 20-day window after closing is tight, delays on the buyer’s side, often caused by incomplete seller documentation, can generate penalties that escrow may try to recoup from sale proceeds.
The practical lesson: whether you’re worried about your own compliance or your buyer’s, the cleanest path is complete, accurate paperwork submitted well before closing. Vague or missing seller certifications are the most common trigger for penalty exposure on either side of the transaction.
How Does FIRPTA Apply to Installment Sales or Seller Financing?
Installment sales complicate FIRPTA because withholding is normally calculated once, at closing, based on the full amount realized. When you offer seller financing and receive payments over time rather than a lump sum, the buyer as withholding agent still generally must withhold based on the total sales price up front, not a prorated amount tied to each installment payment received.
That structure creates a cash flow problem specific to owner financing: you may not have received the full purchase price yet, but the withholding obligation attaches at the time of the transfer of the property interest, not the payment schedule. Some sellers try to negotiate withholding certificates through Form 8288-B specifically to address this mismatch, since the IRS can sometimes approve an adjusted withholding schedule that better reflects the actual timing of gain recognition under installment sale rules.
If you’re considering seller financing on a Bay Area property and you’re a foreign seller, loop in a CPA or tax attorney before signing any financing terms. The interaction between installment sale tax reporting and FIRPTA withholding is one of the more technical corners of this law, and getting the withholding certificate application wrong at the outset can leave you with cash tied up for months while the IRS processes corrections. This is a case where the standard “wait and reclaim at tax time” fallback becomes far less attractive, given how much longer capital stays locked up under a financed structure.
How Does FIRPTA Affect Estate Tax and Inherited Property?
Inheriting U.S. real property as a foreign national introduces a separate layer of tax exposure that sits alongside, rather than instead of, FIRPTA. When a foreign person inherits property from a U.S. decedent, or when a foreign decedent’s U.S. real property passes to heirs, estate tax rules apply first, often at a significantly lower exemption threshold for nonresident, non-citizen decedents compared to U.S. citizens. That estate tax question gets resolved independently of FIRPTA.
FIRPTA enters the picture later, when the foreign heir eventually sells the inherited property. At that point, the sale is treated like any other disposition of a U.S. real property interest by a foreign person, meaning standard withholding rates apply to the sales price at that future closing. One meaningful advantage: your cost basis in inherited property typically steps up to fair market value as of the date of death, which can significantly reduce the taxable gain compared to the original purchase price the decedent paid decades earlier.
That basis step up matters enormously for withholding certificate applications. If you inherited a Los Altos property that has appreciated for 30 years but stepped up in basis at the date of death, your actual taxable gain on a later sale might be modest, making a Form 8288-B application for reduced withholding especially worthwhile. Foreign heirs selling inherited California property should treat the estate tax filing and the eventual FIRPTA withholding as two distinct events requiring separate professional guidance, ideally from the same coordinated legal and tax team.
How Do You Calculate FIRPTA Withholding on a California Home Sale?
Working through actual numbers makes the rules concrete. Consider three scenarios reflecting typical Santa Clara County transactions.
Scenario one: A Sunnyvale home, investment property with sales price exceeding the typical residence exception limit. No residence exception applies due to the high sales price regardless of buyer intent. Standard 15% withholding on the amount realized means a substantial sum held back at closing. If the seller’s actual taxable gain is much smaller, a Form 8288-B application filed well before closing could reduce that figure substantially.
Scenario three: A $2.2 million Saratoga home, foreign trust ownership, minimal gain. Standard withholding would total $330,000. This is precisely the situation where filing early pays off. Waiting until days before closing eliminates any chance of certificate approval before funds are due.
What’s Your Practical FIRPTA Timeline as a Foreign Seller?
A short checklist prevents most of the delays that catch sellers off guard.
- Confirm your FIRPTA status early. Talk to your listing agent and escrow officer as soon as you decide to sell, not after you accept an offer.
- Secure or confirm your ITIN. If you’ve never filed a U.S. tax return, start the Form W-7 process well before listing.
- Gather basis and improvement documentation. Purchase records, capital improvement receipts, and prior tax filings support a stronger withholding certificate application.
- Consult a CPA or tax attorney about Form 8288-B. Do this 30 to 90 days before your anticipated closing date, not after you’re already in contract.
- Keep a U.S. bank account open or arrange a trusted U.S.-based payments specialist, since banking rules under the U.S. PATRIOT Act can complicate wiring proceeds internationally after closing.
- Tell escrow about your FIRPTA situation on day one so they build the correct forms and timeline into your closing package from the start.
The most common pitfalls: sellers who apply for an ITIN too late, sellers who close without a pending withholding certificate and then wait months for a refund, and sellers who close their U.S. bank account before proceeds or refunds arrive, creating a repatriation headache that a little planning would have avoided.
Why Local Escrow Experience Changes the FIRPTA Timeline
Eight years and more than $650 million in closed Bay Area transactions have shown one pattern consistently: sellers who loop in an experienced listing agent early get through FIRPTA cleanly, while those who wait scramble. Santa Clara County escrow officers handle foreign-seller closings regularly, but the timing bottleneck is almost always the same, an ITIN or withholding certificate application started too late to influence the closing date.
An agent who has coordinated dozens of these transactions knows which title companies process foreign-seller documentation efficiently and can flag the 8288-B timeline before you’re locked into a closing date that doesn’t leave room for IRS processing, as detailed in Maine’s helpful real estate guidance blog. That’s the difference between a smooth escrow and months of waiting on a refund. For sellers researching California’s capital gains rules alongside FIRPTA, understanding how the two interact before listing avoids surprises at the closing table.

FIRPTA compliance is one more reason a listing strategy for foreign or nonresident sellers needs to start earlier than a typical Silicon Valley sale. An experienced Bay Area real estate agent brings years of transaction experience, including work with international and out-of-state owners navigating withholding questions, to every listing in Silicon Valley areas. Whether you need help timing a Form 8288-B application around your closing date or simply want an escrow team that has handled foreign-seller paperwork before, reach out to explore your Bay Area home sale and get a coordinated plan for withholding, timing, and net proceeds before you list.
If you’re considering a related move such as using a 1031 exchange to defer gain rather than triggering a taxable sale, that’s a conversation worth having before you sign a listing agreement, not after.
An Editorial Take on FIRPTA for Foreign Home Sellers
That approach fails California sellers specifically, because it ignores how state withholding through Form 593 stacks on top of federal withholding at the same closing table, often catching sellers by surprise on the exact day they expected full proceeds.
The conventional advice to “just file for a refund later” undersells how long capital sits frozen. If you’re withholding $200,000 or more of your own money for months while the IRS processes a return, that’s not a minor inconvenience. It’s a real cost, especially for sellers who need those proceeds to buy a new property or repatriate funds home.
What the research actually supports is this: the sellers who come out ahead are the ones who treat FIRPTA as a pre-listing task, not a closing-day surprise. Start the ITIN and withholding certificate conversation the moment you decide to sell, before you’ve even picked a listing price. That single shift in timing does more to protect your proceeds than any amount of paperwork filed after the fact.
