Client needs your W-9? Fax it securely in under 2 minutes — free, no account needed.
Why Fax a W-9?
The W-9 contains sensitive information — your name, address, and taxpayer identification number (SSN or EIN). Many businesses prefer receiving W-9s by fax rather than email because fax transmission is point-to-point and doesn't pass through third-party email servers. It's a secure, widely accepted method for transmitting tax documents.
How to Fax a W-9 with FaxTerra
Fill out your W-9, save it as a PDF or take a clear photo. Go to faxterra.com/send, upload the form, enter your client's fax number, and send. FaxTerra uses 256-bit encryption and sends your fax clean — no ads, no watermarks, no third-party branding. Your W-9 arrives exactly as you sent it.
Security Considerations
Since a W-9 contains your SSN or EIN, security matters. FaxTerra encrypts all transmissions with 256-bit TLS and encrypts documents at rest with AES-256. Your document is deleted from our servers after delivery confirmation. We never share your documents with third parties.
Frequently Asked Questions
Is faxing a W-9 more secure than email?
Generally yes. Fax is a point-to-point transmission, while email passes through multiple servers. The IRS and many security-conscious businesses recommend fax over email for documents containing SSNs.
Can I fax a W-9 for free?
Yes. FaxTerra offers 10 free pages per month. A W-9 is 1 page, well within the free limit.
Do I need to include a cover page?
It's recommended. FaxTerra's optional cover page lets you include the recipient's name and a message (e.g., "W-9 for [Your Name], as requested"). This helps the recipient identify your fax.
