The U.S. real property interest section in Part II of Form 8288 is used to report withholding tax on payments related to the disposition of U.S. real property interests. This includes sales, exchanges, and certain other transactions. The section requires the reporting person to provide the name and TIN of the foreign person, the description of the property, the date of the transaction, and the amount of the payment. This information is necessary for the IRS to ensure proper reporting and withholding of taxes on income derived from U.S. real property.
