Which contractor tax form do you collect, W-9 or W-8BEN?

Last updated: 2026

Two questions, one answer. Find out whether to collect a W-9, a W-8BEN, or a W-8BEN-E from your contractor before you pay. Built for US founders and finance teams. Collecting the right form first matters: the IRS Instructions for Form W-8BEN warn that "failure to provide a Form W-8BEN when requested may lead to withholding at the foreign-person withholding rate of 30% or the backup withholding rate under section 3406" (IRS). For 2026, the Form 1099-NEC and 1099-MISC reporting threshold also rose from $600 to $2,000 for US payees under the OBBBA (RSM US).

Answer two questions

We map your answers to the exact IRS form to collect.

Two questions

Is the contractor a US person or a foreign person?

A US person is a US citizen, green-card holder, or resident alien meeting the IRS substantial presence test, or a US entity.

Is the contractor an individual or an entity?

An entity is a corporation, partnership, LLC, or other organisation. An individual is a single person.

This is general information, not tax or legal advice

This picker is a general guide for US payers and does not replace professional advice. Edge cases such as effectively connected income, intermediaries, and disregarded entities can change the answer. Confirm the specifics with a qualified tax professional before you pay.

One common edge case: effectively connected income

If a foreign contractor's income from you is effectively connected with a US trade or business, that contractor gives Form W-8ECI instead of Form W-8BEN or W-8BEN-E. This is the most common reason the picker's answer is not the final answer, so flag it with your tax adviser if the contractor has a US office, US staff, or otherwise operates a US business.

The three forms, explained

Form W-9, for US persons

A US person gives you Form W-9. A US person is a US citizen, a US lawful permanent resident (green-card holder), or a resident alien who meets the IRS substantial presence test, plus US entities such as US LLCs, corporations, and partnerships. The W-9 captures the payee's legal name and TIN so you can report payments correctly. Read the Form W-9 glossary entry for the field-by-field walk-through.

Form W-8BEN, for foreign individuals

A foreign individual who is the beneficial owner of the payment gives Form W-8BEN, the Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals). It certifies the contractor is not a US person and can be used to claim a tax treaty benefit. The IRS Instructions for Form W-8BEN are direct: "Do not send Form W-8BEN to the IRS. Instead, give it to the person who is requesting it from you." Read the Form W-8BEN glossary entry for the field detail.

Form W-8BEN-E, for foreign entities

A foreign entity such as a foreign corporation, partnership, or foreign LLC gives Form W-8BEN-E, the entity version of the W-8BEN. It is longer because it asks the entity to classify itself for both Chapter 3 and Chapter 4 (FATCA) purposes. Read the Form W-8BEN-E glossary entry for the detail.

Where the work is performed still matters

The picker tells you which form to collect. It does not on its own decide whether you withhold US tax. Per the IRS source-of-income rule: "The place, where the personal services are performed, generally determines the source of the personal service income, regardless of where the contract was made, or the place of payment, or the residence of the payer." So a foreign contractor working entirely outside the US generally has foreign-source income with no US withholding, regardless of which W-8 form is on file.

Common questions

Which tax form do I collect from a contractor?+

A US person, individual or entity, gives Form W-9. A foreign individual gives Form W-8BEN. A foreign entity gives Form W-8BEN-E.

What is a US person for tax form purposes?+

A US person is a US citizen, a US lawful permanent resident (green-card holder), or a resident alien who meets the IRS substantial presence test for the year, plus US entities such as US LLCs, corporations, and partnerships. US persons give Form W-9. Read more in the substantial presence test glossary entry.

W-8BEN or W-8BEN-E, which one?+

A foreign individual completes Form W-8BEN. A foreign entity such as a foreign corporation, partnership, or foreign LLC completes Form W-8BEN-E.

Does a US payer ever collect a W-8ECI instead?+

Yes, in one common edge case. If a foreign person's income from you is effectively connected with a US trade or business, that foreign person gives Form W-8ECI instead of a W-8BEN or W-8BEN-E. Confirm with a tax adviser.

Do I file the form with the IRS?+

No. The contractor gives the form to you, the payer, and you keep it on file. The IRS Instructions for Form W-8BEN say "Do not send Form W-8BEN to the IRS. Instead, give it to the person who is requesting it from you." Form W-9 works the same way, the requester keeps it. Keeping these forms on file is what backs up your reporting, and reporting moves the needle: contractors whose pay was reported on a Form 1099-MISC reported 77% of that compensation on their returns, versus just 29% when no 1099 was filed (Congressional Research Service).

Does collecting a W-8 form mean I have to withhold US tax?+

Not on its own. Source of personal service income generally follows where the work is performed, per the IRS source-of-income rule. Services performed entirely outside the US are generally foreign-source income, generally not subject to US withholding, regardless of which W-8 form is on file. The flip side matters too: most US-source income paid to a foreign person carries a default 30% withholding tax unless a tax treaty lowers it (IRS), so the form on file plus where the work happens together drive the outcome. Confirm the specifics with a tax professional. For the collection checklist itself, see the W-8BEN collection checklist.
