What is FIRPTA and why does it matter for ITIN?

FIRPTA (Foreign Investment in Real Property Tax Act) requires US buyers to withhold 15% of the gross sale price when a foreign person sells US real estate. The seller files Form 8288-B with an ITIN to apply for a reduced withholding certificate based on actual gain. Without an ITIN the 15% sits with the IRS until a tax return is filed and accepted.

Can I buy US property without an ITIN?

Yes. Buying property does not require an ITIN at closing. But the moment the property generates rental income or is sold, the IRS requires the foreign investor to have an ITIN to file Form 1040-NR. Most investors apply for the ITIN as part of the closing process to avoid delays later.

Does owning property through an LLC change the ITIN need?

Partially. The LLC needs an EIN regardless. A single-member LLC owned by a foreign investor is disregarded for federal tax purposes, so the investor still files Form 1040-NR personally and needs an ITIN. A multi-member LLC issues Schedule K-1s requiring each foreign member to have an ITIN.

How long does the ITIN take for a real estate investor?

The IRS publishes a 7 to 11 week processing window. Real estate ITINs filed under Exception 4 (closing of a real estate sale by a foreign person) can be processed alongside Form 8288-B without waiting for a year-end tax return. A Certifying Acceptance Agent shortens the cycle and verifies the passport locally.

ITIN for Real Estate: Tax IDs for Foreign Property Investors

Why Does a Foreign Real Estate Investor Need an ITIN?

Three real-world events make the ITIN essential:

Renting out the property. Rental income is reportable on Form 1040-NR. The investor needs an ITIN to file.
Selling the property.FIRPTA withholds 15% of the gross sale price unless a Form 8288-B reduced withholding certificate is approved — which requires an ITIN.
Deducting expenses. Property taxes, mortgage interest, depreciation, and operating expenses can offset rental income only when filed under a valid ITIN on Form 1040-NR.

For the full investor breakdown see ITIN for real estate investors.

How Does FIRPTA Withholding Work With an ITIN?

FIRPTA requires the US buyer (or the closing agent) to withhold 15% of the gross sale price when a foreign person sells US real estate. With an ITIN, the seller files Form 8288-B before closing to request a reduced withholding certificate based on actual capital gain — often dropping the withheld amount to a small fraction of the original 15%.

Without an ITIN, the 15% sits with the IRS and is only refunded after the seller files a complete Form 1040-NR for the year of sale, typically the following spring.

What Reason Code Does a Real Estate Investor Use on Form W-7?

(b) Non-resident alien filing a US tax return. Most rental-income investors use this.
(a) Tax treaty benefit. When claiming a reduced rate on rental income under a US tax treaty.
(h) with Exception 4. When applying under the FIRPTA disposition path before a year-end return is due.

What Documents Does a Real Estate ITIN Application Require?

Form W-7 with reason code (b), (a), or (h) checked
Current passport (or two approved alternatives)
Tax return (Form 1040-NR) OR exception document (closing statement, sale contract, withholding certificate request)
For LLC-owned properties: EIN paperwork and operating agreement

When Should a Real Estate Investor Apply for the ITIN?

Apply at the same time the purchase contract is signed. The 7 to 11 week processing window means the ITIN is typically ready before the first rental period ends or the first sale closes. Investors who wait until tax season often miss FIRPTA reduction deadlines. For LLC-structured deals see also ITIN for LLC owners.

Frequently Asked Questions

Yes, in almost every case. Foreign investors who buy US property need an ITIN to file Form 1040-NR, claim deductions against rental income, apply for a FIRPTA withholding certificate when selling, and to report effectively connected income. Without an ITIN, FIRPTA withholding at 15% on the gross sale price cannot be reduced or refunded.
