Fax vs Mail
Is it better to fax or mail to the IRS? Fax or mail, pick one. If mailing, use certified mail, and never send originals. The only thing that makes faxing faster is the 2-3 days of mail time not incurred.
Fax Cover Letter
A fax cover letter is an important document used by a person sending a fax to inform the recipient of essential information that may not be included in the fax.
