Applying for a U.S. TIN (Taxpayer ID Number)
Non-U.S. publishers resident in a country that maintains an income tax treaty with the U.S. and that issues tax identification numbers used for income tax reporting purposes may enter their foreign (non-U.S.) income tax identification number in KDP’s tax interview to claim treaty benefits (i.e., a reduced rate of U.S. tax withholding on their royalty income). For a list of countries that have an income tax treaty with the United States, check the IRS website.
If, however, you reside in a country that maintains an income tax treaty with the U.S. but the country does not issue a tax identification number used for income tax reporting purposes, you must provide a U.S. TIN to claim treaty benefits.
You can apply for a U.S. TIN by following the instructions below to obtain either an Individual Taxpayer Identification Number (ITIN) for individuals or an Employer Identification Number (EIN) for non-individuals. If you are in process of applying for a U.S. TIN, you may complete the Tax Interview without the TIN. Once you receive your TIN from the IRS, take the interview again.
