An ITIN comes up constantly for international buyers. The short answer: you don't always need one to buy, but you will likely need one if you finance, rent, or owe U.S. tax. Here is when and why.
What an ITIN is
An Individual Taxpayer Identification Number (ITIN) is a U.S. tax ID issued by the IRS to people who need to file or be identified for U.S. tax but are not eligible for a Social Security number — including many foreign property owners.
When you need one
You will generally need an ITIN if you finance the purchase, rent the property (rental income is U.S.-taxable and reportable), or otherwise have to file a U.S. tax return — including FIRPTA reconciliation when you sell. A cash purchase you don't rent may not require one immediately.
How to get one
You apply with IRS Form W-7, usually alongside a tax filing or through an IRS-authorized Certifying Acceptance Agent, with proof of identity and foreign status (typically your passport). A cross-border CPA usually handles this efficiently.
We coordinate it for you
Because an ITIN ties into financing, taxes, and FIRPTA, our international process connects you with the right lender and CPA so the ID, the loan, and the closing all line up. See how we help international buyers →
