Form W-8IMY must be signed and dated by a person authorized to sign a declaration under penalties of perjury on behalf of the person whose name is on the form. By signing Form W-8IMY the authorized representative, officer, or agent also agrees to provide a new form within 30 days following a change in circumstances (unless no future payments will be made to the intermediary or flow-through entity by the withholding agent and the requestor does not need an updated form for chapter 4 purposes).

A withholding agent may allow you to provide this form with an electronic signature. The electronic signature must indicate that the form was electronically signed by a person authorized to do so (for example, with a time and date stamp and a statement that the form has been electronically signed). Simply typing your name into the signature line is not an electronic signature. A withholding agent may also rely on an electronically signed withholding certificate if you provide any additional information or documentation requested by the withholding agent to support that the form was signed by you or other person authorized to do so. See Regulations section 1.1441-1(e)(4)(i)(B).
