Does AttachKit file or submit my W-8BEN?

No. AttachKit only helps you fill the PDF in your browser. Form W-8BEN is given to the US payer or withholding agent who requested it — the IRS instructions say not to send it to the IRS. AttachKit never submits anything for you.

Which fields does AttachKit fill automatically?

Only common profile fields it can map, such as your name and permanent-residence address. Form-specific entries — country of citizenship, US or foreign tax ID, date of birth, and any tax-treaty claim — are left for you to review and complete. This isn't tax advice.

How long does a W-8BEN stay valid?

Per the IRS instructions, a W-8BEN generally remains in effect from the date you sign it through the last day of the third succeeding calendar year, unless a change in circumstances makes the information incorrect. Check the official instructions for your situation.

Where do I get the official blank form?

Download the current Form W-8BEN (Rev. October 2021) directly from IRS.gov, then drop it into AttachKit to fill it. We link the official PDF so you always start from the genuine current edition.

Fill Form W-8BEN online — free, in your browser

Form W-8BEN is how a foreign individual certifies their non-US status to a US payer or withholding agent — a brokerage, bank, or company paying you US-source income. You give it to the requester, not to the IRS. Bring the official blank PDF from IRS.gov, drop it into AttachKit, and it auto-fills the common biographic fields from your saved profile, on your device. You then review and complete the W-8BEN-specific parts (citizenship, treaty claims, TIN) yourself.

Who needs it: Foreign (non-US) individuals who receive US-source income — such as nonresident aliens with a US brokerage or bank account, contractors paid by a US company, or those claiming a tax-treaty rate. Entities use Form W-8BEN-E instead.
