FIRPTA is often misunderstood as a 15% tax — it’s not.
In many cases, it is a withholding deposit, and foreign sellers may receive a refund depending on their situation after filing a U.S. tax return.
If you are selling U.S. real estate and are considered a “foreign person” for tax purposes, FIRPTA may require 10% or 15% of your gross sale price to be withheld at closing.
This guide explains how FIRPTA works in 2026, who it applies to, how withholding is calculated, how refunds work, and what foreign sellers should prepare before closing.

What Is FIRPTA?
FIRPTA stands for the Foreign Investment in Real Property Tax Act.
Under IRS rules, when a foreign person sells U.S. real estate, the buyer is generally required to withhold 15% of the gross sales price and send it to the IRS.
This withholding is not necessarily the final tax owed. It is a prepayment toward potential capital gains tax.
The purpose of FIRPTA is to ensure that foreign sellers pay any U.S. tax due on gains from the sale of U.S. property.
In most transactions involving foreign sellers, the buyer or closing agent is responsible for ensuring FIRPTA withholding is properly handled.
Who Is Considered a “Foreign Person” Under FIRPTA?
For FIRPTA purposes, a “foreign person” may include:
- A non-resident alien individual
- A foreign corporation
- A foreign partnership
- A foreign trust or estate
U.S. citizens are not subject to FIRPTA.
Green card holders are generally considered U.S. residents for tax purposes and are typically not treated as foreign persons, but residency rules can be complex. The IRS substantial presence test may also affect classification.
Before listing property, sellers should confirm their tax residency status.
How FIRPTA Applies to Jointly Owned Property
When property is jointly owned, FIRPTA withholding is generally applied proportionally based on each owner’s share.
If one owner is a U.S. person and the other is a foreign person:
• Withholding typically applies only to the foreign owner’s portion
• Proper allocation documentation is required
This distinction is important in mixed-status marriages and family ownership structures.
How the 15% FIRPTA Withholding Works
FIRPTA withholding is calculated on the total sale price, not on the profit.
Example 1: $800,000 Home Sale
Sale price: $800,000
Required withholding (15%): $120,000
Even if the seller only made a $100,000 gain, the withholding is still based on the full $800,000.
Example 2: $1,200,000 Property Sale
Sale price: $1,200,000
Required withholding (15%): $180,000
Again, the IRS receives $180,000 at closing — regardless of the actual profit.
This is why many foreign sellers are surprised at the amount withheld.
Example 3: Low Gain but High Withholding
Sale price: $600,000
Original purchase price: $550,000
Gain: $50,000
Estimated capital gains tax: ~$10,000
FIRPTA withholding (15% of $600,000): $90,000
Even though tax owed may only be $10,000, $90,000 is withheld at closing — requiring refund processing.

Is FIRPTA the Final Tax?
No.
The 15% withholding is a prepayment, not necessarily the final tax bill.
After the sale:
- The seller files a U.S. tax return.
- Actual capital gains tax is calculated.
- If withholding exceeds the actual tax owed, the seller receives a refund.
In many cases, the actual capital gains tax is lower than 15% of the sale price, meaning the seller may be entitled to a refund.

How to Estimate Net Proceeds Before Listing
Foreign sellers should estimate expected net proceeds before listing property.
Key factors include:
• Estimated sale price
• 15% FIRPTA withholding
• Capital gains tax liability
• Closing costs
• Realtor commissions
Planning early prevents liquidity surprises at closing.
FIRPTA Withholding vs Actual Capital Gains Tax
| Item | FIRPTA Withholding | Capital Gains Tax |
|---|---|---|
| Based On | Gross sale price | Net gain |
| Rate | Typically 15% | Varies (0–20%+) |
| Paid At | Closing | Tax filing |
| Refund Possible? | Yes | N/A |
FIRPTA withholding is often higher than the final tax owed because it is calculated on the full sale price rather than profit.
How FIRPTA Interacts With Capital Gains Tax Rates
FIRPTA withholding is 15% of the gross sale price, but actual capital gains tax is calculated differently.
Nonresident aliens are generally taxed on U.S. real property gains at capital gains rates, which may range from 0% to 20% depending on gain level and holding period.
Because withholding is based on the full sale price — not the gain — it often exceeds the final tax liability.
This difference is why many foreign sellers receive refunds after filing their U.S. tax return.
Realistic FIRPTA Planning Timeline (Before and After Sale)
Understanding FIRPTA early — ideally before listing your property — can prevent liquidity surprises.
A realistic planning timeline may look like this:
Before Listing:
• Confirm tax residency status
• Estimate potential capital gain
• Determine whether Form 8288-B is appropriate
During Contract Period:
• Coordinate with escrow regarding FIRPTA handling
• Prepare required documentation
• Confirm ITIN validity
At Closing:
• Verify withholding calculation
• Confirm proper completion of Forms 8288 and 8288-A
After Closing:
• Track stamped Form 8288-A
• Prepare tax return
• Monitor refund timeline
Proactive planning reduces financial uncertainty.
The $300,000 Primary Residence Exception
There is an important FIRPTA exception for certain sales under $300,000.
If:
- The sale price is $300,000 or less, and
- The buyer intends to use the property as a primary residence
Then FIRPTA withholding may not be required.
This exception does not apply to higher-value transactions and requires proper certification by the buyer.
(We cover this in detail in our separate guide on the $300,000 exception.)
How to Reduce FIRPTA Withholding Before Closing
Foreign sellers may apply for a Withholding Certificate (Form 8288-B) to reduce or eliminate withholding before closing.
This is typically done when:
- The expected capital gains tax will be significantly less than 15% of the sale price.
- The seller can document the lower estimated tax liability.
Timing is critical. The application should generally be submitted before closing.
If approved, the IRS may authorize a reduced withholding amount.
What Happens After Closing?
At closing:
- The buyer (or closing agent) files Form 8288 and Form 8288-A.
- The 15% withholding is sent to the IRS.
Afterward:
- The seller files a U.S. tax return for the year of sale.
- Actual capital gains tax is calculated.
- Any excess withholding is refunded.
Refund timelines can vary depending on IRS processing times. Many sellers want to know how long FIRPTA refunds actually take, which we explain in our detailed FIRPTA Refund Timeline (2026) guide.
FIRPTA vs State Real Estate Withholding
FIRPTA is a federal law.
Some states also impose separate real estate withholding requirements.
State-level withholding rules vary by jurisdiction and may apply regardless of federal FIRPTA status.
Sellers should confirm whether:
• Their state requires separate withholding
• Additional forms must be filed
• Refund claims must be submitted at state level
Federal and state rules operate independently.
Common FIRPTA Mistakes
Foreign sellers often make avoidable errors, including:
- Assuming green card status automatically exempts them.
- Not planning for liquidity at closing.
- Confusing state withholding rules with FIRPTA.
- Missing deadlines for applying for a withholding certificate.
- Assuming the 15% is the final tax amount.
- Assuming escrow automatically determines residency correctly
- Not understanding joint ownership allocation
- Forgetting state-level withholding obligations
Proper preparation before listing the property can prevent surprises.
What Happens If FIRPTA Is Not Withheld?
Failure to comply with FIRPTA withholding rules can create serious financial consequences — especially for buyers.
If required withholding is not made:
- The buyer may become personally liable for the tax that should have been withheld
- Interest may accrue from the date of transfer
- Additional penalties may apply
Even if the seller has already received full proceeds, the IRS may pursue the buyer for the required withholding amount.
