Said from IRS and I owe money, they are suing me unless I paid right then. So I told them I worked at the IRS and he went into a rant cursing me out and hung up. I called back and told him we know where he is and coming to arrest him today.

There are numerous telephone and email scams in which individuals claim to be employees of the Treasury Department. These scammers often state that they are from the “Department of Legal Affairs,” offer grant money in exchange for you wiring a small payment, or threaten to arrest you within a short period of time unless payment is made. Do not provide personal information or payment to these individuals.  Their actions are crimes under Titles 18 and 31 of the United States Code, and the Treasury Office of Inspector General is working to stop them.

If they claim to be from Treasury, report  it to OIGCounsel@oig.treas.gov with a description.  If it was a phone contact, include:
the exact date and time that you received the call(s)
the phone number of the caller
the geographic location and time zone where you received the call
a description of the communication.

If they claim to be from the Internal Revenue Service (IRS) or it is about taxes, report it to the Treasury Inspector General for Tax Administration at:

Automated voice stumbling over script that they are the IRS and they have started legal action against us.
Total scam, ignore and report.

States they are calling for investigation and the IRS is suing me. Will not provide information without me giving out a lot of personal information

I owe money to the IRS and they're going to arrest me which is a bunch of baloney
