Form W-8BEN: what it means

W-8BEN is an IRS form in which a foreign individual confirms non-US status and claims a reduced treaty rate of US tax on dividends.

W-8BEN is a form of the US Internal Revenue Service (IRS) for individuals who are neither US citizens nor US tax residents. With it an investor confirms foreign status and claims a reduced tax rate under the double tax treaty between the US and their country.

Without the form, a broker withholds 30% from dividends of US companies. For residents of Ukraine the treaty rate is 15%: the form lists the RNOKPP as the foreign tax number and Ukraine on line 9. A US tax number is not needed for this.

The form goes to the broker, not the IRS. It is valid until the end of the third calendar year after signing, and if circumstances change a new one must be provided within 30 days. The reduced rate does not apply to dividends from real estate investment trusts (REITs) for Ukrainians.
