Foreign Contractors: W-8 vs W-9 — Which Form Do You Need?
Paying a foreign contractor? Learn whether to collect a W-8BEN or W-9, when withholding applies, and how to stay IRS-compliant — without costly mistakes.
1Why the W-9 Is Not Always the Right Form
Most small businesses default to requesting a W-9 from every contractor they pay — but that only applies to U.S. persons, including U.S. citizens and resident aliens. When a contractor is a foreign individual or a foreign business entity, the correct form is a W-8, not a W-9. Sending the wrong form wastes time and can create a false sense of compliance that exposes your business to IRS penalties.
2The W-8 Series: Which Version Applies to Your Contractor
The IRS issues several W-8 variants, and the right one depends on the contractor's situation. W-8BEN is for foreign individuals (sole proprietors and freelancers), while W-8BEN-E is for foreign business entities such as corporations or LLCs organized outside the U.S. W-8ECI applies when a foreign person has income effectively connected to a U.S. trade or business. In practice, most small businesses paying independent foreign freelancers will collect a W-8BEN.
3Withholding Rules That Catch Small Businesses Off Guard
When you pay a U.S. contractor without a valid W-9, you may be required to apply 24% backup withholding. Foreign contractors carry a different default: the standard withholding rate on payments to foreign persons for U.S.-source income is 30%, unless a tax treaty reduces it. The contractor's W-8BEN lets them claim a treaty benefit and a lower rate — but if you don't have a valid W-8 on file before you pay, you're responsible for withholding the full 30% and remitting it to the IRS using Form 1042-S at year-end.
4Do Foreign Contractors Get a 1099-NEC?
No — you do not file a 1099-NEC for payments made to foreign contractors. Instead, payments subject to withholding are reported on Form 1042-S, Foreign Person's U.S. Source Income Subject to Withholding, which is due to both the IRS and the contractor by March 15 of the following year. If the services were performed entirely outside the United States, the income may not be U.S.-source income at all, and neither 1042-S nor 1099-NEC would apply — but you should document that determination carefully.
5How to Confirm a Contractor's Foreign Status
You cannot always tell a contractor's tax status from their name, location, or payment method. A contractor with a U.S. mailing address or a U.S. bank account may still be a nonresident alien. The safest practice is to ask every new contractor to self-certify their status before the first payment — U.S. persons complete a W-9, and foreign persons complete the appropriate W-8. Tools like W-9 Nudge can automate the W-9 collection step for domestic contractors, giving you a clean workflow that flags anyone who indicates foreign status and needs a different form.
6W-8 Expiration and Re-Collection Requirements
Unlike W-9 forms, which generally remain valid until information changes, W-8 forms expire. A W-8BEN is valid for the calendar year it is signed plus three full calendar years after that — so a form signed in March of one year expires at the end of the third following year. If a foreign contractor's form lapses and you continue paying them, you must revert to 30% withholding until you collect a new, valid W-8. Build a renewal reminder into your vendor management process so expiration doesn't catch you mid-project.
7Practical Steps Before Paying Any New Contractor
Before issuing a first payment, ask the contractor directly: are you a U.S. person for tax purposes? If yes, collect a W-9 and retain it. If no, identify which W-8 variant applies, collect it, and determine whether a tax treaty reduces your withholding obligation — the IRS maintains a full list of current tax treaties on its website. Keep signed copies of all forms in your records for at least four years. Getting this right upfront is far less costly than unraveling incorrect withholding or missing 1042-S filings after year-end.
