IRS Cautions Tax Pros About New EFIN Email Scam

The IRS warned that scammers are posing as tax software providers and requesting EFIN documents from tax professionals.

The IRS and the agency’s Security Summit partners alerted tax professionals on Thursday of a scam email impersonating various software companies in an attempt to steal electronic filing identification numbers (EFINs).

The IRS warned that scammers are posing as tax software providers and requesting EFIN documents from tax professionals under the guise of a required verification to transmit tax returns. The scam artists attempt to steal client data and tax preparers’ identities, creating the potential for them to file fraudulent tax returns for refunds.

To help protect tax professionals against this new scam, the IRS is hosting a special series of educational webinars for the tax community, beginning on Feb. 12 and running each day next week.

“With filing season underway, scammers use this time of year to target tax professionals as well as taxpayers in hopes of stealing information that can be used to try filing fraudulent tax returns,” IRS Commissioner Danny Werfel said in a statement. “The IRS and the Security Summit partners have noticed a new surge of an EFIN scam email that targets professionals. This scam serves as a powerful reminder that tax professionals should ensure strong security at their practices, including reminding employees to be careful with any emails coming in that could be posing as an official communication. A little extra caution can mean a world of difference for tax professionals during this busy period.”

The IRS said it has already received dozens of reports of the scam targeting tax professionals. They should be on alert for a scam email that includes a U.S.-based area code for faxing EFIN documents and also provides instructions on obtaining EFIN documentation from the IRS e-Services site if unavailable. Scam variations being seen use different fax numbers for software vendors. Other warning signs of the scam include inconsistencies in the email wording and a German footer in the email.

The IRS cautions tax professionals who receive these emails not to respond and not to proceed with any of the steps displayed in the email. The body of the fraudulent email states:

Dear [recipient_email_address],

Help us protect you.

Because many Electronic Filing Identification Numbers (EFINs) are stolen each year and used to file fraudulent tax returns, the IRS has asked software vendors, such as Software A, to verify who the EFIN owner is by getting a copy of the IRS issued EFIN document(s). Our records show that we do not have a document for one or more of the EFINs that you transmit with.

What this means for you: Until your EFIN is verified, you will be unable to transmit returns. Please provide a copy of your EFIN Account Summary from IRS e-Services, with a status of ‘Completed’, to Software B for verification.

To send us your EFIN Summary document:

1. Fax to Software B at 631-995-5984


If you do not have the above documentation you can get a copy of your IRS Application Summary from IRS e-Services by following the below steps or call the IRS e-Services helpline at 866-255-0654.
