Frequently asked questions
What IRS fax number should I use?
Use the fax number printed on the specific IRS notice or in the official form instructions you’re responding to — it varies by form and state. We don’t change or route the number; your fax goes exactly where you address it.
Can I fax Form 2848 or 8821 here?
Yes. Upload the completed PDF, enter the IRS fax number from the form instructions, and pay once to send.
Will I get confirmation the IRS received it?
You’ll see a delivery status for the transmission to the IRS fax line. The IRS does not send back an electronic receipt — keep your delivery confirmation for your records.
