There are several variations of the scam: unexpected refund deposits to your bank account using compromised bank routing information, suspicious paper checks coming in the mail and, in one case reported in Maryland, a fraudulent refund check that appeared to have been deposited using a smartphone.

According to the IRS, the victim will then receive a call or recorded message saying they need to return the funds to a collection agency, which is actually the scam account.

If you pay the scammers, you will get a double-whammy hit to your bank account when the IRS or your bank realizes that the deposit was bogus and withdraws the funds.

The number of victims jumped from a few hundred to a few thousand in just days after more tax practitioner data breaches, according to the IRS.

The IRS has these recommendations to avoid getting scammed:

If you notice a suspicious deposit, contact your bank to have the money returned to the IRS and call the IRS at 800-829-1040.

If you receive a paper check, write “void” in the endorsement field on the back and return it to the location printed on the check.

If you mistakenly cashed the erroneous refund check, submit a check for the full amount to the IRS location near you.
