The IRS warned taxpayers again of continuing scams by criminals pretending to be agency personnel and using "aggressive and threatening phone calls" to get money from their targets.
There is a deluge of these phone scams, Commissioner John Koskinen said in a Feb. 2 news release, but people shouldn't be fooled. "We continue to say if you are surprised to be hearing from us, then you're not hearing from us," he said.
The IRS always will mail a bill before calling, the news release said, and it will never call to demand immediate payment, ask for credit or debit card numbers on the phone, bar an opportunity to question or appeal what it says is owed or threaten to bring in law enforcement.
The phone tactics remain among the IRS's annual "Dirty Dozen" list of scams, the agency said.
