RS does not file lawsuits. Tax disputes are civil matters. 90% of all IRS tax disputes are settled administratively. IRS has absolutely no authority to call on local law enforcement for anything. Local law is never involved in IRS tax disputes. If LE is necessary, US Marshals do the job. IRS does not cold call anyone and all contacts are initiated by US mail.
This is the number I was told to call back. Saying the IRS is filing a lawsuit against me. First call I've ever received saying I owe money. I know I don't owe the IRS anything because I pay my taxes every year.
Just received a call from these yahoos with a recorded message stating it was the IRS, blah blah blah BS. The number that showed on my caller ID is 1-722-422-5687, the message told me to call 206-973-3241.
