WALTHAM, Mass. (WJAR) — Tax season is synonymous with scams.

This year, there are two clever new scams to worry about.

“This is a particularly ingenious way that people are being tricked,” said Steve Weisman, who is the author of "Identity Theft Alert" and scamicide.com.

Weisman, who also works as a professor at Bentley University, said the first new scam is pretty savvy because scammers aren’t stealing your money -- at least not right away.

“The income tax identity thief used your social security number, filed an income tax return, but instead of getting the refund sent to them, they have the refund wired to you -- into your bank account,” said Weisman.

You know it's too much money, but you keep quiet.

Then comes the letter, or phone call, or email from someone pretending to work for the IRS, saying "We made a mistake -- we sent you too much money."

“And so people are then sending that money back,” said Weisman. “But they're sending that money back to the scammer, rather than the IRS.”

Weisman said that's not the only new scam we have to worry about.

Another tax scam is taking advantage of IRS attempts to stop tax identity theft.

“The scammers are always good at managing to manipulate whatever the cure is to make the disease worse,” warned Weisman.

Weisman said the IRS has set up new filters to detect red flags on tax returns. If your return doesn't pass their filters, the IRS will contact you with one of four letters.

Now, scammers are posing as IRS agents -- sending copycat letters or calling taxpayers -- saying, "There's a problem with your return. We need to confirm some information."

“And they're going to be asking, ‘What's your social security number? What's your bank account number?’ And all of this other information,” said Weisman. “You can't do it.”

The solution to both these scams is the same. If you get a mysterious refund or a letter saying you've been flagged for fraud, call the IRS at 1-800-829-1040.
