Upload your W-9 Form from iPhone 14 Pro
Alternatively, tap the upload icon to import your W-9 Form from Files, iCloud Drive, or any connected cloud storage. The Dynamic Island on iPhone 14 Pro can show TigerFax fax status updates while you're using other apps — you'll see when your fax is sent without switching back to the app.

Add a confidentiality cover page
Since W-9 Forms contain sensitive information protected under IRS, add a cover page with a confidentiality notice. TigerFax includes built-in cover page templates.
