How to Fax a W-9 Form from iPhone 13

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.

Never fax a W-9 without a confidentiality cover page — it contains your Social Security Number or EIN

What you'll need

  • iPhone 13 running iOS 15+
  • 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 13: Step-by-Step

  1. 1

    Download TigerFax

    Install TigerFax from the App Store on your iPhone 13. It's free to start — no credit card required.

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

  2. 2

    Scan your W-9 Form with iPhone 13

    Open TigerFax and tap the camera icon. Position your iPhone 13 about 12 inches above the W-9 Form and let the auto-capture detect the edges. The iPhone 13's sensor-shift OIS on the wide camera reduces camera shake during document scanning. For best results, scan in a well-lit area and let the auto-capture trigger automatically.

  3. 3

    Upload your W-9 Form from iPhone 13

    Alternatively, tap the upload icon to import your W-9 Form from Files, iCloud Drive, or any connected cloud storage. iOS 15 on iPhone 13 supports Quick Note and improved Shortcuts integration, so you can create a shortcut to open TigerFax and start a fax directly from your home screen.

    💡 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.

    💡 Tip: Never fax a W-9 without a confidentiality cover page — it contains your Social Security Number or EIN

  6. 6

    Review and send

    Preview your W-9 Form to verify all pages are included and legible. Tap Send. You'll receive a delivery confirmation when the fax is received.
