How to fax it
- Fill in Form 2848, one per taxpayer. Spouses on a joint return each file their own.
- Sign it by hand. Digital, electronic or typed signatures aren’t valid on a 2848 sent by fax or mail.
- Find the number for the taxpayer’s state above. If you checked line 4 (a specific use that isn’t recorded on the CAF), fax it to the IRS office handling that matter instead.
- Send it from dimefax.com/send and keep the delivered confirmation.
Tips
- The IRS processes faxed 2848s in about 3 business days and doesn’t tell you when it’s done.
- If you’ve faxed it, don’t also submit it online at IRS.gov/Submit2848: one way only.
- To revoke a power of attorney, fax a copy with “REVOKE” written across the top of page 1, signed and dated.
Dimefax costs 10¢ a page and you’re only charged if the fax goes through. On the web, page credits come in packs of 50 for $4.99, 100 for $9.99 or 200 for $19.99; the Dimefax iPhone app also sells 10 for $0.99. Credits you don’t use stay in your account and last as long as you fax once a year.
