The decision point

When you pay a person for services, the IRS cares about two things:

  1. Is the person a US person or not?
  2. If not, was the service performed in the US or outside?

US persons → 1099-NEC (for $600+)

Non-US persons, work performed outside US → Usually no US reporting

Non-US persons, work performed inside US → Withholding and 1042-S

W-8BEN is how the contractor certifies status #1 (non-US person).

What Form W-8BEN does

When you need a W-8BEN

Before paying any non-US person — ideally before the first payment. The form is:

You collect and keep the form. You don't send it to the IRS unless requested. The contractor signs and dates it.

When you do NOT need to file 1099-NEC for them

You don't issue a 1099-NEC if:

Most remote workers overseas fit this exactly. No 1099 required. The contractor reports income in their home country.

When you DO owe withholding

US-sourced income rule

If a non-US contractor performs services while physically in the US (visits, conferences, etc.), those payments are US-source income. You're supposed to withhold 30% (or less if treaty reduces it) and file Form 1042-S reporting the payment.

In practice, most solo businesses don't encounter this — their overseas contractors never set foot in the US. But if yours do, the rules are strict.

The 30% backup withholding trap

If you pay a foreign person for services and they haven't given you a W-8BEN, the default IRS position is:

  1. Withhold 30%
  2. File Form 1042-S
  3. Pay withheld amount to IRS

This happens whether or not the income is US-source under the strict letter of the rules. The W-8BEN is your safe harbor.

Practically: get every non-US contractor to fill out a W-8BEN before their first invoice. Don't let this slide.

Collecting the form

The W-8BEN is a 1-page form. You send them a copy (PDF or digital form), they complete and return. Keep the original signed version.

Tools that automate W-8BEN collection:

Treaty benefits

Some tax treaties reduce withholding on certain income types. Example: under the US-UK treaty, royalties might be withheld at 0% instead of 30%. The contractor claims the treaty benefit on W-8BEN Line 10.

For most service payments to non-US contractors performing work outside the US, treaty benefits are irrelevant — there's no US tax to begin with, so nothing to reduce.

What to do if you already paid without a W-8BEN

  1. Request W-8BEN retroactively
  2. If contractor signs and dates it, you have the safe harbor going forward
  3. For past payments: if services were performed outside US, documentation of that fact (invoices showing location, communication records) is your defense
  4. Don't file 1099-NEC for non-US contractors — the SSN/EIN field won't match IRS records and creates a worse problem

Solo LLC owner's workflow

  1. Contractor agreement specifies where work will be performed
  2. Before first payment: contractor fills out W-8BEN (if non-US) or W-9 (if US)
  3. You keep the form in your files
  4. Pay via Wise, PayPal, or bank transfer
  5. Track payments in your books as Line 11 (Contract labor) on Schedule C
  6. At year-end, issue 1099-NEC only to US contractors with W-9 on file
  7. Non-US contractors with W-8BEN and overseas work: no 1099, no 1042-S, nothing further

Does the contractor owe US tax?

Usually no. If the work was performed outside the US and they're a non-resident alien for US tax purposes, the income is not US-source and not subject to US tax. They report and pay tax in their home country.

Exception: if the contractor is in the US working on a visa with tax obligations, they may owe US tax. That's their problem, not yours (you just collect the W-8BEN and file 1042-S as required).
