Which W-8 form do I need?

There are five W-8 forms, and payers rarely tell you which one they expect. Answer the questions below and get the right one — with a free generator for the common cases.

Are you a U.S. person? (a U.S. citizen or resident individual, or an entity organized in the United States)

The W-8 family, explained

Form W-9 — you're a U.S. person

W-8 forms are only for foreign persons. A U.S. citizen, a resident individual, or an entity organized in the United States certifies its taxpayer identification number on Form W-9 instead — even when the payer asking happens to be foreign.

Form W-8BEN — foreign individual, own income

A foreign individual who beneficially owns the income — a freelancer with U.S. clients, an investor receiving U.S. dividends — certifies foreign status on Form W-8BEN, and claims a reduced treaty withholding rate on it if their country has a tax treaty with the U.S.

Form W-8BEN-E — foreign entity, own income

A foreign company, partnership, or trust that beneficially owns the income uses Form W-8BEN-E. It adds an entity classification and a FATCA status — most operating companies are Active NFFEs — alongside any treaty claim.

Form W-8ECI — income effectively connected with a U.S. business

When the income is effectively connected with a trade or business the recipient conducts in the United States, Form W-8ECI applies. That income isn't handled by withholding at all — it's reported on a U.S. tax return and taxed on a net basis.

Form W-8IMY — intermediaries and flow-throughs

A recipient acting for others — an intermediary, nominee, or flow-through entity passing income to its partners or beneficiaries — certifies that role on Form W-8IMY, generally with withholding statements attached for the people behind it.

Form W-8EXP — governments and exempt organizations

Foreign governments, central banks of issue, international organizations, and certain foreign tax-exempt organizations certify their special status on Form W-8EXP to claim the exemptions those statuses carry.
