THE QUICK ANSWER
W-8BEN documents a foreign individual’s status as the beneficial owner of income and, where applicable, a claim to treaty benefits. Complete your identifying information, address the tax-ID requirements for your situation, make only supported treaty claims, and give the signed form to the requester.
First, make sure you need W-8BEN
W-8BEN is generally for a foreign individual, not a foreign company. A U.S. citizen or resident alien generally uses W-9, even when living abroad. A foreign entity may use W-8BEN-E, and other circumstances can call for a different form in the W-8 family.
The kind of income and where services are performed also matter. Income effectively connected with a U.S. trade or business generally involves W-8ECI. A nonresident individual claiming a withholding exemption for certain personal services performed in the United States may need Form 8233 or W-4 instead. Confirm the purpose of the request before filling boxes.
Get your information together
Have your legal name, citizenship, permanent residence address, relevant tax identification numbers, and any reference supplied by the payer ready. If you intend to claim a tax-treaty benefit, also gather the basis for that claim. Citizenship alone is not enough to establish treaty eligibility.
- Your identity and tax-residence details.
- Your foreign tax identifying number, where required.
- A U.S. SSN or ITIN if your circumstances require one.
- Any applicable treaty article, income category, rate, and qualifying conditions.
- The requester’s instructions for returning the form.
Part I: identify the beneficial owner
Enter the individual beneficial owner’s name and country of citizenship. Follow the instructions if you have more than one citizenship. Use your permanent residence address for the applicable tax-residence rules; it is not simply any address where you can receive mail. If your mailing address differs, enter it separately.
The tax-ID fields serve different purposes. Line 5 is for a U.S. SSN or ITIN when required. Line 6a is for the foreign tax identifying number where applicable. Line 6b is for an eligible claim that an FTIN is not legally required; it is not a way to skip a number you have misplaced.
Complete the reference number and date-of-birth fields as applicable under the instructions and the requester’s circumstances. Do not invent a tax number, substitute a company number for an individual number, or assume that every field is optional because the form lets you type past it.
Part II: claim treaty benefits only when applicable
A completed W-8BEN does not automatically grant a reduced withholding rate. A treaty claim depends on an applicable treaty and your eligibility for the relevant income. Treaty residence can differ from citizenship, and the existence of a treaty with a country does not mean every payment qualifies.
Where a claim requires line 10, supply the article and paragraph, requested rate, type of income, and explanation of the qualifying conditions. Do not enter a convenient-looking rate from another contractor’s form. If the payer requests clarification, resolve the claim with them before treating the paperwork as settled.
Part III: review, sign, and return it
Read the full certification and sign only if it is accurate. If someone signs for the beneficial owner, the authorization requirements matter. Return the completed W-8BEN to the withholding agent or payer that requested it, rather than sending it to the IRS.
Keep a dated copy and a renewal reminder. Under the general validity rule, a form remains valid through December 31 of the third calendar year following the year it was signed, unless a relevant change makes it incorrect earlier. Different validity rules can apply in particular circumstances.
Beside’s W-8 request flow supports a guided W-8BEN or an upload of a completed form. If you need W-8BEN-E or another W-8 variant, use the appropriate completed document. Review the final form before submitting; the collection tool does not determine treaty eligibility for you.
Common questions
It depends on the payment, claim, and applicable rules. W-8BEN has separate U.S. and foreign TIN fields. Check the instructions for your situation rather than assuming a U.S. TIN is always required or never required.
W-8BEN is generally for individuals. Foreign entities usually consider W-8BEN-E, with exceptions for disregarded entities, intermediaries, and other situations. Identify the beneficial owner first.
No. It documents status and any applicable claim. Withholding depends on the income and tax rules, including any valid treaty benefit.
