I answered the call and a woman said, "Hi, this is Sara (I think) and I am calling you about your IRS tax debt." She then hung-up. I have no tax debts and she never bothered to ask who I was before asserting I did have such a debt, so I'm going to assume this was a cold call from scammer or telemarketer.

You need to contact the real IRS and file a complaint..

I don't have outstanding IRS payments!!!! Leave me alone! DNC list works like our goverment should......hey, let's let them run our HEALTH CARE!!!!!!!!

*OW* Hey, the DNC list is for telemarketers, but won't protect you from these kind of scammers sadly!  Yeah I agree it sucks, but thats the way it is. You need to file a complaint with the real IRS and not the DNC.. Which is down anyway from the government being shut down. You can file a complaint with your state Attorney general and the FBI also.. Otherwise tell the IRS, they want to know about these things, same as the DEA wants to know about the DEA scammers..

Do factor in the fact that some of these creeps are not even in the US pulling this garbage also, that opens up a whole new bottle of red tape..

didn't answer it. the time was 6:26.
