Faxing does not increase the speed of processing by the IRS. If provided a fax number, it should be fine to use.
You can fax a completed Form SS-4 and receive a return fax in about one week. Without a return fax number, it will take two weeks. Visit www.taxpayeradvocate.irs.gov or call 877-777-4778 to complete the form, then mail or fax it within 30 days.
Mailing provides a paper trail to track submissions and ensure delivery. The IRS recommends sending returns by certified mail with return receipt. As of December 2022, the IRS is taking longer to process mailed documents. Consider other options for time-sensitive issues.
Sending Documents to the IRS
What is the best way to send documents to the IRS?
Always use a secure method, such as certified mail return receipt requested, when sending returns and documents to the IRS. This will confirm the IRS received your documents.
You can submit documents online through the IRS’s secure portal. This saves time and ensures prompt delivery.
To mail returns, use Certified Mail through USPS. This allows you to track the documents in transit to the IRS. Make sure to retain the mailing receipt.
For faster processing, e-file tax returns instead of mailing paper forms. As of April 2022, the IRS received 96 million e-filed returns.
For time-sensitive issues, avoid mailing returns near the tax deadline, as the IRS mail backlog can cause delays. Consider e-filing or faxing instead.
Always address returns correctly with sufficient postage. Make sure envelopes are postmarked by the filing deadline.
Faxing Security Concerns
Is it safe to send a fax to the IRS?
Sending sensitive or highly confidential documents is better sent through fax. As the transmission of the document only involves a phone network and the physical document, it is received directly by the recipient with less risk of interception.
