How to fax it
- Fill in Form 8821. Naming more than two designees? Check line 2 and attach a list.
- Sign it by hand. Electronic signatures are only accepted when you submit online.
- Find the number for the taxpayer’s state above. If you checked line 4 (specific use), fax it to the IRS office handling that matter instead.
- Send it from dimefax.com/send and keep the delivered confirmation.
Tips
- A new 8821 revokes earlier ones unless you attach copies of the ones you want to keep in effect.
- The IRS processes faxed 8821s in about 3 business days.
- You can also submit it online at IRS.gov/Submit8821 instead. Use one way, not both.
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.
