As the April filing deadline approaches, the Internal Revenue Service warns taxpayers to be alert to tax time phone scams, where aggressive criminals pose as IRS agents in the hope of stealing money or personal information.

Phone scams or “vishing” (voice phishing) continue to pose a major threat. The scam has cost thousands of people millions of dollars in recent years, and the IRS continues to see variations on these aggressive calling schemes.

Phone scams again made the IRS’ Dirty Dozen list, an annual compilation of some of the schemes that threaten taxpayers not only during filing season but throughout the year.

The IRS is highlighting each of these scams on consecutive days to help raise awareness and protect taxpayers. The IRS also urges taxpayers to help protect themselves against phone scams and identity theft by reviewing safety tips prepared by the Security Summit, a collaborative effort between the IRS, states and the private-sector tax community.

“Taxpayers should be on the lookout for unexpected and aggressive phone calls purportedly coming from the IRS,” said IRS Commissioner Chuck Rettig. “These calls can feature scam artists aggressively ordering immediate payment and making threats against a person. Don’t fall for these.”

Beginning early in the filing season, the IRS generally sees an upswing in scam phone calls threatening arrest, deportation or license revocation, if the victim doesn’t pay a bogus tax bill. These calls most often take the form of a “robo-call” (a text-to-speech recorded voicemail with instructions to call back a specific telephone number), but in some cases may be made by a real person. These con artists may have some of the taxpayer’s information, including their address, the last four digits of their Social Security number or other personal details.

The Treasury Inspector General for Tax Administration, the federal agency that investigates tax-related phone scams, says these types of scams have cost 14,700 victims a total of more than $72 million since October 2013.

How do the scams work?

Criminals make unsolicited calls and leave voicemails with urgent callback requests claiming to be IRS officials. They demand that the victim pay a bogus tax bill by sending cash through a wire transfer, prepaid debit card or gift card.

Many phone scammers use threats to intimidate and bully a victim into paying. The phone scammers may alter or “spoof” their caller ID to make it look like the IRS or another agency is calling. The callers may use IRS employee titles and fake badge numbers to appear legitimate.

The IRS also reminds taxpayers that scammers often change tactics. Variations of the IRS impersonation scam continue year-round and tend to peak when scammers find prime opportunities to strike. Tax scams can be more believable during the tax filing season when people are thinking about their taxes.

Here are some things the scammers often do, but the IRS will not do. Taxpayers should remember that any one of these is a tell-tale sign of a scam.

The IRS will never do the following

• Call to demand immediate payment using a specific payment method such as a prepaid debit card, gift card or wire transfer. Generally, the IRS will first mail a bill to any taxpayer who owes taxes.

• Threaten to immediately bring in local police or other law-enforcement groups to have the taxpayer arrested for not paying.

• Demand that taxes be paid without giving taxpayers the opportunity to question or appeal the amount owed.

• Ask for credit or debit card numbers over the phone.

• Call about an unexpected refund.

Stay alert to scams that use the IRS or other legitimate companies and agencies as a lure. Tax scams can happen any time of year, not just at tax time. For more information visit Tax Scams and Consumer Alerts on www.IRS.gov.
