FIRPTA and ITIN Guide 2026: Foreign Real Estate Tax Withholding

FIRPTA (Foreign Investment in Real Property Tax Act) requires 15% withholding on the gross sales price when a foreign person sells US real estate. On a $500,000 property sale, $75,000 is withheld and sent to the IRS before you see any proceeds. Your ITIN is essential to file Form 1040-NR and reclaim any over-withheld amount. Many foreign sellers owe less than 15% in actual capital gains tax, making the FIRPTA refund process critical. This guide covers how FIRPTA works, how to reduce withholding, how to file for a refund, and the role your ITIN plays in every step.

What Is FIRPTA and How Does It Affect Foreign Property Owners?

FIRPTA is a US federal law enacted in 1980 under IRC Section 897. It ensures that foreign persons pay US capital gains tax when they sell US real property. Without FIRPTA, foreign sellers could sell US property, leave the country, and never pay tax on the gain.

FIRPTA works through mandatory withholding at the time of sale. The buyer (or the buyer's agent) withholds a percentage of the gross sales price and submits it to the IRS using Form 8288. This withholding is not a tax itself — it is a prepayment toward your actual tax liability, which you determine when you file Form 1040-NR.

Why Do You Need an ITIN for FIRPTA?

Your ITIN is required at 4 stages of the FIRPTA process:

  1. Form 8288-B (withholding certificate application). Your ITIN is entered on this form to request reduced withholding before closing. Without an ITIN, the IRS cannot process your application.
  2. Form 8288-A (withholding statement). The buyer files this with your ITIN to report the amount withheld. You need the copy with your ITIN to claim the withholding credit.
  3. Form 1040-NR (tax return). You enter your ITIN on your annual tax return to report the sale and claim a refund of any over-withheld amount.
  4. State tax returns. Many states impose their own withholding on foreign sellers. Your ITIN is required on state forms as well.

If you do not have an ITIN when selling US property, apply immediately. The ITIN application process takes 7 to 11 weeks. Plan ahead by applying months before your anticipated sale date.

How Do You Reduce FIRPTA Withholding with Form 8288-B?

If your actual capital gains tax is less than 15% of the sales price, you can apply for a withholding certificate to reduce the amount withheld at closing.

  1. Calculate your estimated tax liability. Determine your capital gain (sales price minus adjusted basis). Apply the applicable capital gains rate (15% or 20% for long-term gains).
  2. File Form 8288-B with the IRS. Submit the application with your ITIN, property details, sales price, adjusted basis, and estimated tax. File as early as possible — processing takes approximately 90 days.
  3. Receive the withholding certificate. The IRS issues a certificate specifying the reduced withholding amount. Provide this to the buyer and closing agent.
  4. Close with reduced withholding. The buyer withholds the IRS-approved amount instead of the full 15%.

Example savings:

You sell a property for $400,000. You purchased it for $350,000. Your capital gain is $50,000. At 15% capital gains rate, your tax is $7,500. Without Form 8288-B, $60,000 is withheld (15% of $400,000). With the withholding certificate, only $7,500 is withheld. You keep $52,500 more at closing.

How Do You Get a FIRPTA Refund?

If the 15% FIRPTA withholding exceeds your actual capital gains tax, file for a refund on Form 1040-NR. Follow these 5 steps.

  1. Obtain Form 8288-A from the buyer. This form shows the amount withheld and sent to the IRS. You need Copy B for your records.
  2. Calculate your actual capital gain. Sales price minus adjusted basis (purchase price + closing costs + improvements - depreciation). Long-term gains (held over 1 year) are taxed at 15% or 20%.
  3. File Form 1040-NR. Report the sale on Schedule D and Form 8949. Enter the FIRPTA withholding as tax paid.
  4. Attach Form 8288-A. Include your copy showing the withholding amount.
  5. Request direct deposit. Provide your US bank account routing and account numbers. Refunds take 8 to 16 weeks for paper-filed FIRPTA returns.

Do States Have Their Own FIRPTA Withholding?

Yes. Many states impose additional withholding on real estate sales by non-residents (both foreign and out-of-state sellers). State rates are separate from and in addition to the federal 15% FIRPTA withholding.

  • California: 3.33% of gross sales price
  • Hawaii: 7.25% of gross sales price
  • Maryland: 8% of gain
  • Oregon: 4% of gain or 2% of gross price
  • Georgia: 3% of gross sales price
  • New York: Varies by gain and residency

Combined federal and state withholding can exceed 20% of the gross sales price. Plan your sale timeline and cash flow accordingly. States with no income tax (Florida, Texas, Nevada, Wyoming) do not impose additional withholding.

What Is the FIRPTA Timeline for ITIN Holders?

The complete FIRPTA process spans several months. Plan these milestones carefully.
