How to Fax IRS Form 2848 Online (Power of Attorney) | SecurelyFax

Form 2848 is Power of Attorney and Declaration of Representative — the form that authorizes a tax professional to represent you in front of the IRS. The IRS lists fax as an accepted submission method in the form's current instructions, with destination fax numbers that depend on where the taxpayer lives. SecurelyFax sends the signed Form 2848 from email, browser upload, or a phone scan and returns a delivery confirmation you keep with your records.

What Form 2848 does

Form 2848 grants a named representative — typically a CPA, enrolled agent, or attorney — the authority to act for you on specific tax matters before the IRS. The form lists which tax years, which tax types, and what the representative is and is not allowed to do. Without a 2848 on file, the IRS will not discuss your account with that representative.

Why people fax 2848 instead of mailing it

Tax representation is often time-sensitive: a notice has a deadline, a transcript request is blocking a refund, an audit conversation is scheduled. Fax gets the authorization onto the IRS record faster than mail and produces a delivery receipt you can hand to the practitioner. Submitting Form 2848 through the IRS's Submit Forms 2848 and 8821 Online tool may also be available; pick whichever path the current instructions support for your situation.

Common 2848 mistakes that delay processing

Missing tax-period coverage, a representative line without a CAF or PTIN, an unchecked authorization box that the IRS treats as off, or a taxpayer signature outside the dated window — any of these can bounce the form. Tax representation pages aren't the place to learn the form for the first time; the instructions on IRS.gov walk through every box.
SecurelyFax is not affiliated with the IRS and is not a tax practitioner. It transmits the completed, signed form to the destination number you provide and returns a delivery confirmation. Your representative or the IRS instructions are the source of truth for which boxes to check and which number to send to.
