Over the next 5 weeks, the IRS will send letters to certain e-Services product users who must either go online or call the e-Services e-Help Desk to validate their identities. These letters will go to those users who can access the Transcript Delivery Service and who have been active within the past year. Remember, you will NOT get an e-mail from the IRS, or a phone call. This will be an actual letter via US mail. If you receive one of those letters and are not sure if it’s legitimate or a scam, call your tax professional to double check.
