"In recent years, thousands of people have lost millions of dollars and their personal information to tax scams and fake IRS communication. Scammers use the regular mail, telephone, fax or email to set up their victims. This page looks at the different scams affecting individuals, businesses, and tax professionals and what do if you if you spot a tax scam.
REMEMBER: The IRS doesn't initiate contact with taxpayers by email, text messages or social media channels to request personal or financial information. In addition, IRS does not threaten taxpayers with lawsuits, imprisonment or other enforcement action. Recognizing these telltale signs of a phishing or tax scam could save you from becoming a victim." (IRS)
