How FillWise handles Form W-8BEN

FillWise fills this form the regular way: the AI reads each field's printed caption, its tooltip and its options, and answers from your notes.

The file also carries Adobe XFA data next to its regular form fields. FillWise fills the regular fields and leaves the XFA part out, so the result opens in Acrobat, Preview or Chrome alike.

The form has a digital signature field. FillWise leaves it empty: signing is yours.
