W-8BEN

Form W-8BEN is the "Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals)". A foreign individual who is the beneficial owner of income subject to US withholding gives it to the withholding agent or payer, usually their broker, and does not send it to the IRS (IRS: About Form W-8BEN). Companies and other entities use a different form, W-8BEN-E.

What it does

• Certifies foreign status, so the broker treats the holder as a non-US person.
• Claims treaty benefits, where the holder's country has a tax treaty with the US. Without a valid form, the broker may apply the default 30% withholding rate (IRS: NRA withholding).

How long it lasts

According to the IRS instructions, a W-8BEN generally stays in effect from the date it is signed until the last day of the third succeeding calendar year, unless a change in circumstances makes any information incorrect. A form signed in 2026 would therefore generally run to 31 December 2029. If information becomes incorrect, the holder must tell the withholding agent within 30 days and provide a new form (IRS instructions for Form W-8BEN).

How it applies to digital credit

UK holders of US-issued preferreds such as STRC, STRF or SATA usually complete a W-8BEN when they open an account with a broker that offers US securities. Many brokers do this online. The form governs the withholding on every dividend payment. For daily-paying series such as SATA and SATS, that means every business day.

The W-8BEN only affects US withholding. It does not decide UK tax, or how a distribution that the issuer expects to be return of capital is finally classified.

What to check

• That the form is on file and not expired
• The treaty article and rate claimed
• Your country of tax residence as shown on the form
