CALLING PEOPLE WITH TAX LIENS. A few decades back, a couple of companies in Colorado started the bold practice of contacting people with tax liens...by phone!? This is now an established practice by the now numerous tax relief companies in that state (and elsewhere). There are questions about it's legality (if you aren't a licensed tax professional) HERE. If you are a business who has a tax lien for 941 taxes, you will almost assuredly have heard from these folks. The big bone to pick besides the legality is when they overstate urgency for people to act. No need to scare people into hiring you!
