Be on alert for new tax scams. The IRS is warning about new ways thieves are stealing from taxpayers. In one scam, criminals pose as debt collection agency officials acting on behalf of the IRS. They contact taxpayers to say refunds were deposited in their accounts in error. They ask the taxpayers to send the money back. In another scam, taxpayers receive automated calls saying erroneous refunds were deposited and threatening criminal charges and “blacklisting” of Social Security numbers if the money isn’t returned. Hang up on these types of calls immediately.
