Step-by-step: faxing the IRS from iPhone

Get the IRS fax number for your form

Use our IRS fax number reference or check IRS.gov for your specific form. Common: 855-641-6935 (SS-4 EIN), 855-214-7522 (2848 Western), 855-214-7519 (2848 Eastern).

Open Faxend on iPhone

Either tap the Faxend app icon or open Safari and go to faxend.com/send. Both work, no account required.

Add your IRS form

Tap "Add Document", choose "Scan with Camera" for paper or "Upload File" for digital PDFs.

If scanning: capture each page

Hold the iPhone parallel to the page. Faxend auto-detects edges and snaps. Tap "Add Page" for multi-page forms. Tap "Done" when finished.

Enter the IRS fax number

Country: United States (selected by default). Enter the fax number with no spaces or dashes (Faxend auto-formats).

Fill the cover sheet form

Name, business name, EIN/SSN, contact phone, form name. Faxend builds a clean IRS-compliant cover sheet from these fields.

Pay with Apple Pay

$2.99 for up to 5 pages. One-tap with Face ID or Touch ID via Apple Pay. Or use a credit card.

Send and save confirmation

Tap "Send Fax". Wait 30-90 seconds. When successful, screenshot the confirmation page or download as PDF for your records.

iPhone-specific tips

Use HEIC/JPEG photo, not Live Photo: Live Photos can confuse the scanner. Use standard photo mode.
Lighting matters: Scan in even daylight, avoid shadows or harsh overhead light. Camera scanner adjusts contrast but can't recover detail in dark areas.
Hold phone steady: Even slight motion can blur tax form numbers. Use a stable surface or both hands.
Verify before paying: Tap the "Preview" button to see the final fax (cover sheet + your form) before sending.
Save fax confirmation to Photos: Screenshot lands in Photos automatically, never relies on the cloud.

Troubleshooting common issues

"Camera permission denied": Open iOS Settings → Faxend → Camera → toggle on.

"File too large": Faxend supports up to 7MB raw upload. Compress PDFs in Files (long-press → Compress) or split multi-page documents.

"Transmission failed": The IRS line may be busy or the number may be wrong. Wait 15 minutes and retry. Verify the fax number on IRS.gov.

"Apple Pay not available": Add a card in Wallet first (Settings → Wallet & Apple Pay → Add Card). Or use a credit card directly.
