How to Fax a W-9 Form from iPhone 16

Need to send a W-9 to a client or employer? Faxing is still the preferred method for many businesses, and TigerFax handles it in minutes.

What you'll need

  • iPhone 16 running iOS 18
  • TigerFax app (free on the App Store)
  • Your W-9 Form (physical copy to scan, or a PDF/image file)
  • The recipient's fax number
  • A cover page with confidentiality notice (recommended)

How to Fax a W-9 Form from iPhone 16: Step-by-Step

  1. 1

    Download TigerFax

    Install TigerFax from the App Store on your iPhone 16. It's free to start — no credit card required.

    💡 Tip: TigerFax is optimized for iOS 18 and works on all iPhones running iOS 15 or later.

  2. 2

    Scan your W-9 Form with iPhone 16

    Open TigerFax and tap the camera icon. Position your iPhone 16 about 12 inches above the W-9 Form and let the auto-capture detect the edges. The iPhone 16's 48MP main camera captures document text at exceptional resolution. Use the Camera Control button on the side to trigger a scan hands-free — perfect when you need both hands to hold a document flat.

  3. 3

    Upload your W-9 Form from iPhone 16

    Alternatively, tap the upload icon to import your W-9 Form from Files, iCloud Drive, or any connected cloud storage. iOS 18 on iPhone 16 supports enhanced Files app integration. You can import documents from iCloud Drive, Dropbox, Google Drive, or any connected storage directly into TigerFax.

    💡 Tip: PDF format preserves W-9 Form formatting best. If you have a digital copy, upload it instead of scanning for the clearest result.

  4. 4

    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.
