Last verified: 9 October 2026 against the IRS form and instructions (Rev. October 2021) · Not tax advice

Answer each line in plain English. The tool checks for the usual mistakes, then gives you your answers line by line so you can copy them into the official W-8BEN — or download the filled PDF where available.

Who this is for: individuals outside the US who've been asked for a W-8BEN. Companies need W-8BEN-E instead.

Private by design: everything runs in your browser. Nothing is saved or sent.

Part I — About you Line 1 · Full name (as the owner of the income) Line 2 · Country of citizenship Line 3 · Permanent residence address (street, apt — no PO box)

City, state, postal code

Country

My mailing address is different (line 4)

Line 5 · US SSN or ITIN (only if you have one and it's required) Line 6a · Foreign tax ID (FTIN) (from your country of residence)

Line 6b · My country doesn't legally require me to have a tax ID

Line 7 · Reference number (optional — e.g. your account number with the payer) Line 8 · Date of birth

We'll format it as MM-DD-YYYY, as the form requires.

Part II — Tax treaty (optional)

I want to claim tax treaty benefits

Part III — Signing Print name of signer (usually the same as line 1)

I'm signing as an agent under a power of attorney for the person on line 1

You sign and date the form yourself. We don't add a signature.

Next: open the official W-8BEN from irs.gov, enter these answers on each line, sign and date it, and give it to the payer who asked. Don't send it to the IRS.

Frequently asked questions

Is this W-8BEN tool free?

Yes. It's free, needs no account, and runs entirely in your browser.

Do you store my details?

No. Nothing you type is saved or sent to us. Close the tab and it's gone.

Does this tool submit my W-8BEN?

No. You give the completed form to the payer who asked for it. W-8BEN is never sent to the IRS.

Can I sign here?

You sign the form yourself. If your payer accepts electronic signatures, follow their process; typing your name alone isn't an electronic signature under the IRS instructions.

What does the tool check?

Common mistakes: PO box addresses, a US citizenship entry, date format, a tax ID entered with the 'not required' box ticked, and a treaty claim without any tax ID.
