ITIN for Foreign Real Estate Investors: FIRPTA, Rental Income & How to Apply (2025–2026)

The moment foreign sellers of U.S. real estate feel the FIRPTA problem most acutely is at the closing table. The buyer's escrow agent informs them that 15% of the sale proceeds — potentially hundreds of thousands of dollars — will be withheld and sent to the IRS.

The seller asks what they can do about it. The answer involves Form 8288-B, the ITIN, and a timeline that ideally begins well before closing day.

This guide explains what FIRPTA requires, how an ITIN fits into it, and what foreign real estate investors need to know for rental income as well.

What FIRPTA Is (and Why It Exists)

FIRPTA — the Foreign Investment in Real Property Tax Act — requires the buyer of U.S. real estate to withhold a portion of the sale proceeds when the seller is a foreign person. The withheld amount is a prepayment toward the seller's U.S. tax liability on the gain.

The IRS uses buyer-side withholding because foreign sellers can exit the U.S. jurisdiction without paying the tax. FIRPTA's withholding mechanism ensures the IRS gets something before the seller leaves.

The seller can recover any over-withheld amount by filing Form 1040-NR after the sale.

FIRPTA Withholding Rates: Three Tiers

The withholding rate depends on the sale price and how the buyer intends to use the property:

The most important tier for many transactions: if the property sells for $300,000 or less and the buyer is purchasing it as their primary residence, no FIRPTA withholding applies. The sale can close cleanly without any IRS withholding.

This exemption requires the buyer to sign a certification confirming their intent to use the property as a residence. If the buyer misrepresents this, they — not the seller — are responsible for the withholding tax.

Why Foreign Real Estate Investors Need an ITIN

1. Filing Form 1040-NR After a Sale

Whether 15% was withheld or 0%, foreign sellers who realize a capital gain from U.S. real estate are required to file Form 1040-NR to report the sale and calculate actual tax liability. If the tax due is less than the amount withheld, the difference is refunded.

Form 1040-NR requires a personal TIN — specifically an ITIN for foreign nationals.

2. Applying for a Withholding Certificate (Form 8288-B)

If the standard 15% withholding rate would significantly exceed your actual expected tax liability — which it often does, since capital gains are typically taxed at rates below 15% — you can apply to reduce the withholding.

File Form 8288-B (Withholding Certificate for Dispositions by Foreign Persons) with the IRS before or on the closing date. If approved, the IRS issues a withholding certificate specifying a reduced withholding amount.

Submitting Form 8288-B requires an ITIN. If you don't have one, you apply for both simultaneously — and the IRS processes the ITIN within approximately 10 business days when submitted with Form 8288-B, compared to the standard 7–11 weeks.

3. Reporting Rental Income from U.S. Property

Non-residents with U.S. rental property face a default of 30% withholding on gross rental income unless they make the ECI (Effectively Connected Income) election.

The ECI election changes the tax treatment to net income: you pay tax on profit after expenses (mortgage interest, repairs, depreciation, property management) rather than on gross rent. For almost every rental property owner with expenses, this is significantly more favorable.

Making the ECI election requires filing Form 1040-NR — which requires an ITIN.

4. Mortgage Interest Reporting (Exception 3)

If your U.S. property has a mortgage, the lender issues Form 1098 (Mortgage Interest Statement). If you need to use this for U.S. tax reporting, you need an ITIN.

This also qualifies for Exception 3 on Form W-7, which means you can apply for an ITIN without attaching a tax return.

The FIRPTA Timeline: What You Need to Know Before Closing

The withholding certificate process has hard timing requirements:

Before closing: Form 8288-B must be received by the IRS before or on the closing date to affect the withholding at closing. Submit it as early as possible — the IRS needs time to review it.

At closing: The title company or escrow agent withholds either the applicable statutory rate or the amount specified in the withholding certificate. If Form 8288-B is pending (filed but not yet approved), the statutory withholding is held in escrow pending the IRS decision.

After closing: File Form 1040-NR for the tax year of the sale. Report the gain, apply any applicable capital gains rates or treaty benefits, and claim a refund if over-withheld.

For the 10-day ITIN: Submit Form W-7 simultaneously with Form 8288-B. Include the sales contract and the completed Form 8288-B as supporting documentation. The IRS ITIN unit processes these together on an expedited basis.

Rental Income: The Two Options in Plain Terms

Default treatment (without election):

• Tenant or property manager withholds 30% of gross rent
• No deductions for any expenses
• Often results in overpayment of tax

ECI election (with Form 1040-NR):

• Tax applies to net rental income after all deductible expenses
• Deductions include: mortgage interest, property taxes, repairs and maintenance, property management fees, depreciation, insurance
• Almost always results in significantly lower tax

Example: $2,000/month gross rent. Expenses: $1,200/month. Under default treatment, you pay tax on $24,000/year. Under ECI election, you pay tax on roughly $9,600/year — the actual profit.

Apply for the ITIN, make the ECI election on your first 1040-NR, and notify your property manager. Once the election is in place, 30% gross withholding is no longer required.

ITIN vs. EIN for Real Estate Investors

Frequently Asked Questions

My property is under $300,000 and the buyer is using it as their residence. Do I still need an ITIN?

If no withholding applies, you may still need an ITIN to file Form 1040-NR to report the capital gain — unless the gain is exempt from U.S. tax under a treaty. Consult a U.S. tax professional about your specific situation. The ITIN application itself is straightforward if needed.

How quickly can I get an ITIN for a real estate closing?

If you submit Form W-7 simultaneously with Form 8288-B, the IRS processes the ITIN in approximately 10 business days. For standard applications, allow 7–11 weeks. Plan ahead.

I sold U.S. real estate two years ago, 15% was withheld, and I never filed a return. Can I still get a refund?

Yes. You can file Form 1040-NR for the applicable tax year. The statute of limitations for refund claims is generally 3 years from the original filing deadline. For the 2023 tax year, the window closes in April 2027. File and claim the refund before it closes.

Does holding property through a U.S. LLC avoid FIRPTA?

Not automatically. FIRPTA treatment depends on whether the LLC is treated as a domestic or foreign corporation for U.S. tax purposes, among other factors. A foreign-owned U.S. LLC may still be subject to FIRPTA on property sales. Get qualified U.S. tax advice before assuming an LLC structure eliminates FIRPTA.

I have rental property and my tenant just started withholding 30% from rent. What should I do?

Make the ECI election by filing Form 1040-NR for the current year, and instruct your property manager or tenant accordingly. Once the election is in place for the year, the 30% gross withholding requirement is replaced by the net-income approach. Apply for an ITIN now if you don't have one.
