In the last week, I have received two messages on my answering machine at home purporting to be from the IRS, advising me that I owe taxes and if I don’t call them back I may be arrested. I’ve also gotten calls from other people about similar calls.
99% of these are scams. If the IRS has a problem with you, they will mail you notices – they will not call you first. If you want to be sure, don’t call back the number given. Instead, call the IRS at 1.800.829.1040 and they can tell you what, if anything, is going on with your tax account, including whether you owe any money.
