Key takeaways
- Form W-8BEN is given by a non-US individual to the person paying them, not sent to the IRS.
- A form is generally valid until the last day of the third calendar year after the year it was signed, unless circumstances change.
- Without a valid form a payer may withhold at the 30 percent foreign-person rate.
- A treaty claim on line 9 can lower the rate. The payer should keep the form with the payment records.

What W-8BEN is
Form W-8BEN is a certificate of foreign status that a non-US individual gives to a payer of US-source income, so the payer knows whether to withhold tax and at what rate.
Procurement teams meet it when onboarding an overseas freelancer, consultant or royalty recipient. A US company that pays a person in Poland for design work asks the person for a W-8BEN, much as it asks a US contractor for a W-9. The form says who they are, where they live for tax and whether a treaty applies.
Entities such as companies fill in W-8BEN-E instead. US persons fill in a W-9.
A software firm in Texas pays a developer in Lisbon 6,000 for a project. Accounts payable has no W-8BEN on file. Under the instructions, failure to provide the form when requested may lead to withholding at the 30 percent foreign-person rate, which here would hold back 1,800.
The developer fills in the form, claims treaty benefits on line 9 if they apply, and the firm applies the correct rate and files the right returns.
Key parts of the form
| Field | What goes in it | Why it matters |
|---|---|---|
| Part I, name and country | The person's name and country of citizenship. | Must match the contract and the bank account. |
| Tax identification number | A US TIN if there is one, or a foreign TIN on line 6a. | Account holders at US institutions must give a foreign TIN. |
| Address | Permanent residence address, not a PO box or care-of address. | Shows tax residence. |
| Line 9 treaty claim | The country where the person claims residence for treaty purposes. | Only lines claiming a treaty benefit qualify for a reduced rate. |
| Line 10 special rates | Extra statements for certain treaty claims. | Required for some treaty claims. |
| Part III certification | Signature and date. | An unsigned form is not valid. |
