When the seller is a foreign person, FIRPTA usually makes the buyer the one who withholds. The IRS explains the rate, the duty and the ways it can change.

How FIRPTA works

The disposition of a U.S. real property interest by a foreign person is subject to FIRPTA income tax withholding. In most cases, the buyer is the withholding agent and must find out if the seller is a foreign person. If the seller is a foreign person and the buyer doesn’t withhold, the buyer may be held liable for the tax.

The rate

The rate of withholding generally is 15% of the total amount realized. The amount realized is the cash paid or to be paid, the fair market value of other property transferred, and the amount of any liability assumed by the buyer or to which the property is subject.

What can change it

The IRS says withholding is generally not required when the seller gives the buyer a certification, under penalties of perjury, that the seller is not a foreign person, containing name, U.S. taxpayer identification number and home address. It’s also generally not required when the buyer receives a withholding certificate from the IRS that excuses withholding. Notification requirements must still be met.

Who to ask

A closing attorney and a tax adviser can say how it applies to a specific sale.
