What is the difference between Form W-8BEN and W-8BEN-E?

Form W-8BEN is for foreign individuals; Form W-8BEN-E is for foreign entities (corporations, partnerships, trusts). Both certify foreign status and can claim reduced treaty withholding, but W-8BEN-E is far longer because entities must also certify their FATCA (chapter 4) status and, when claiming treaty benefits, their limitation-on-benefits qualification.

Do I file Form W-8BEN with the IRS?

No. You give the completed W-8BEN to the withholding agent — the US payer, broker, or financial institution — not to the IRS. The payer keeps it on file and uses it to apply the correct withholding rate. Do not mail it to the IRS.

How long is a Form W-8BEN valid?

Generally from the date signed through the end of the third succeeding calendar year — roughly three years — unless a change in circumstances makes any information incorrect. A permanent-address or status change requires a new form within 30 days.

Do I need a US taxpayer ID number to claim treaty benefits on a W-8BEN?

Often a foreign tax identifying number (foreign TIN) from your country of residence is sufficient to claim treaty benefits on the standard form. A US ITIN or SSN is required in certain situations, but many treaty claims can be supported with a foreign TIN plus a valid claim in the treaty-benefits section.
