When selling U.S. real estate, foreign sellers face unique tax rules that can be confusing. One of the most important regulations to understand is the Foreign Investment in Real Property Tax Act (FIRPTA). FIRPTA withholding tax is a critical part of the process, designed to ensure the IRS collects taxes on gains from the sale of U.S. property by non-resident aliens. In this post, I will walk you through the essentials of FIRPTA withholding tax, explain how it works, and offer practical advice to help you navigate this complex area with confidence.
What is FIRPTA Withholding Tax?
FIRPTA is a U.S. tax law that requires buyers of real estate from foreign sellers to withhold a portion of the sale price and remit it to the IRS. This withholding acts as a prepayment of the foreign seller’s U.S. tax liability on the gain from the sale. The goal is to prevent foreign sellers from avoiding U.S. taxes by selling property and leaving the country without paying.
The withholding amount is generally 15% of the gross sales price. This means if you sell a property for $1,000,000, the buyer must withhold $150,000 and send it to the IRS. This amount is not the final tax due but a withholding to cover potential tax liability. The actual tax owed is calculated when the seller files a U.S. tax return.
Why is FIRPTA Important?
Understanding FIRPTA withholding tax is crucial because failure to comply can lead to penalties for both the buyer and seller. Buyers who do not withhold the required amount may become liable for the tax themselves. Sellers who do not plan for FIRPTA withholding may face unexpected cash flow issues at closing.

How FIRPTA Withholding Tax Works in Practice
The process starts when a foreign person sells U.S. real estate. The buyer is responsible for withholding the tax at closing. Here’s a step-by-step overview:
Identify the Seller’s Status: The buyer must determine if the seller is a foreign person. This usually involves the seller providing a certification of non-foreign status or a withholding certificate.
Calculate the Withholding Amount: Typically, 15% of the gross sales price is withheld.
Withhold and Remit: The buyer withholds the amount and sends it to the IRS within 20 days of the sale.
Seller Files Tax Return: The seller files a U.S. tax return to report the sale and calculate the actual tax due. If the withholding exceeds the tax owed, the seller can claim a refund.
Exceptions and Reduced Withholding
There are exceptions where withholding may be reduced or waived. For example:
If the property will be used as a residence and the sales price is $300,000 or less, withholding may not be required.
Sellers can apply for a withholding certificate from the IRS to reduce or eliminate withholding if they expect the tax liability to be less than the withholding amount.
These exceptions require careful planning and documentation.

How does FIRPTA affect the buyer?
Buyers play a critical role in FIRPTA compliance. They must withhold the correct amount and remit it to the IRS. Failure to do so can result in the buyer being held liable for the tax, plus penalties and interest.
Buyer Responsibilities
Verify Seller’s Status: Buyers should request a certification from the seller confirming their foreign or non-foreign status.
Withhold Correct Amount: If the seller is foreign, the buyer must withhold 15% of the gross sales price unless a reduced amount is approved.
File Form 8288 and 8288-A: These forms report the withholding and transfer the funds to the IRS.
Keep Records: Buyers should keep all documentation related to the transaction and withholding.
Practical Tips for Buyers
Work with a knowledgeable title company or attorney to ensure FIRPTA compliance.
Request the seller’s certification early in the process.
Consider the withholding amount when negotiating the purchase price and closing costs.
By understanding their obligations, buyers can avoid costly mistakes and delays.
Common Questions About FIRPTA Withholding Tax
What types of property are subject to FIRPTA?
FIRPTA applies to sales of U.S. real property interests, including:
Residential and commercial real estate
Land
Certain personal property associated with real estate (e.g., timber, minerals)
Can the withholding amount be adjusted?
Yes. Sellers can apply for a withholding certificate from the IRS to reduce or eliminate withholding if the expected tax liability is less than the standard 15%. This requires submitting Form 8288-B before closing.
What happens if the seller is a U.S. resident?
If the seller is a U.S. resident or a domestic entity, FIRPTA withholding does not apply. The buyer should obtain a certification of non-foreign status to avoid withholding.
How does FIRPTA withholding affect the seller’s tax return?
The withheld amount is credited against the seller’s U.S. tax liability. When the seller files Form 1040NR or the appropriate tax return, they report the sale and calculate the actual tax due. If the withholding exceeds the tax owed, the IRS will issue a refund.
