W-8BEN vs W-8BEN-E comes down to one question: is the payee a person or a company? A foreign individual signs the W-8BEN. A foreign entity signs the W-8BEN-E, which the IRS says "is used by foreign entities to document their status." Neither one goes to the IRS. You keep it.
General information, not legal or tax advice. Talk to a CPA or attorney about your specific setup.
The question is usually simple. It gets confusing when a developer in Mexico or Colombia sends invoices from a small company they set up, or when someone hands you the wrong form because a previous client asked for it. I see both every few months.
Key Takeaways
- W-8BEN is for individuals. W-8BEN-E is for entities. Match the form to whoever is named on the invoice and receives the money.
- The payer keeps the form on file. The IRS instructions say "Do not send Form W-8BEN-E to the IRS."
- A signed form stays valid through December 31 of the third year after signing, unless circumstances change.
- On the Latin American mainland, only Mexico, Venezuela, and Chile have a US income tax treaty, and for work done entirely abroad the treaty section rarely changes anything.
W-8BEN vs W-8BEN-E Side by Side
| W-8BEN | W-8BEN-E | |
|---|---|---|
| Who signs | Foreign individual | Foreign entity (company, LLC formed abroad, etc.) |
| Current revision | October 2021 | October 2021 |
| Purpose | Foreign status of an individual | Status of an entity for chapter 3 and chapter 4 (FATCA) purposes |
| Who keeps it | You, the payer | You, the payer |
| Valid until | Dec 31 of the 3rd year after signing | Same rule |
| Treaty claim | Part II (lines 9-10) | Has its own treaty section |
Both current revisions are October 2021, and both IRS "about" pages showed no recent developments when I checked in October 2026.
The W-8BEN-E looks scary because it is built for every kind of foreign entity, from a two-person software shop to a bank, and it documents status for both the withholding rules (chapter 3) and FATCA (chapter 4). A small company only completes the parts that apply to it. The owner should read the instructions or ask their own accountant which parts those are. Do not fill it in for them; they are the one certifying it.
How Long the Form Lasts (and What Resets It)
Per the W-8BEN instructions, the form remains in effect from the date it is signed "ending on the last day of the third succeeding calendar year." The IRS example: a form signed September 30, 2015 stays valid through December 31, 2018. The W-8BEN-E follows the same rule.
People often say "it expires after three years." That is close but wrong in a way that matters for your calendar. A form signed in January 2026 and one signed in December 2026 both run through December 31, 2029.
A change in circumstances cuts that short. If something on the form becomes incorrect, for example your contractor moves to the US or changes the country they claim treaty benefits in, the instructions say they must tell you within 30 days and give you a new form. A new company is a different payee, so it needs its own form before you pay it. Put a renewal reminder in your finance calendar and ask every contractor once a year whether anything changed.
The Treaty Section: Usually Irrelevant for LATAM Developers
Part II of the W-8BEN (lines 9 and 10) is where an individual claims treaty benefits, and the W-8BEN-E has its own treaty section. The IRS treaty table lists Mexico, Venezuela, and Chile in Latin America. Chile's treaty is the newest; it entered into force on December 19, 2023. Brazil, Argentina, Colombia, Peru, Costa Rica, and Uruguay are not on the list.
For a developer working entirely from their home country, the treaty claim usually does nothing. Their pay is already foreign-source income with no US withholding, per the IRS. The treaty question matters when work is done inside the US, and in that case the right form is not a W-8BEN at all. The instructions say a nonresident claiming exemption on pay for services performed in the US should provide Form 8233 or a W-4 instead.
A Concrete Version
A 20-person Series A company pays four LATAM contractors directly. Here is how the paperwork lands:
1. Ana, an individual in Guadalajara who invoices in her own name: W-8BEN, signed March 2026, valid through December 31, 2029.
2. A two-person dev shop in Medellin, registered as a Colombian company: W-8BEN-E, signed by the owner.
3. Diego in Santiago, an individual who leaves Part II blank: W-8BEN. Chile has a treaty, but he works only from Chile, so there is nothing to claim.
4. A developer in Buenos Aires who is actually a US citizen: wrong form entirely. He gives you a W-9 and gets a 1099-NEC if you pay him $2,000 or more.
In mid-2027 Ana forms a company and switches her invoices to it. Before you pay the company, collect a form for it, usually a W-8BEN-E. Keep both on file: the old one covers payments to her personally, the new one covers payments to the company.
Total admin: four forms, one renewal reminder per form, about an hour per year. Cheap. The expensive mistake is paying for two years with no form on file and then trying to backfill it during due diligence.
The Honest Counterpoint
Getting the W-8BEN vs W-8BEN-E choice right is the easy part, and it protects you from less than founders think. The form documents that the payee is foreign. It does not prove the relationship is a real contractor relationship. If one "contractor" works 40 hours a week only for you, uses your laptop and Slack, and reports to your engineering manager, their home country may see an employee. In Mexico, Baker McKenzie notes that since 2022 disguising an employee as an independent professional is treated as tax fraud.
That is a classification problem, and no IRS form fixes it. Read contractor vs employer of record before you scale past two or three direct contractors.
Frequently Asked Questions
W-8BEN vs W-8BEN-E: what if my contractor has a single-member company?
Start with whoever is named on the invoice and receives the payment. If the invoice comes from the company and you pay the company's account, ask for a W-8BEN-E. If they invoice personally, a W-8BEN. One exception: if the company is a disregarded entity for US tax purposes, the W-8BEN-E instructions say the single owner provides the form, so an individual owner would sign a W-8BEN. Their accountant can confirm how the entity is treated.
Do I send the W-8BEN to the IRS?
No. The form header says "Give this form to the withholding agent or payer. Do not send to the IRS." Store it with your vendor records, where your CPA and any acquirer's diligence team can find it.
Do I need a W-8BEN if I pay a US staffing company?
No. You pay a US company, so you collect its W-9. If it is a corporation, or an LLC taxed as one, payments are generally not reportable on a 1099-NEC. The foreign paperwork for the engineers is the staffing company's job.
The Bottom Line
Person signs the W-8BEN, company signs the W-8BEN-E, you keep both, and you renew on the calendar-year rule. If you want the bigger picture, start with do you issue a 1099 to a foreign contractor and how to pay overseas developers.
If you would rather skip foreign forms entirely, a staff augmentation provider gives you one W-9 and one invoice. See vetted senior LATAM engineers and compare against the real cost of hiring full-time.
