Saw I had a missed call sent 6:47am today - 1-12-16.  The caller ID said it is from Irs at 1 801-917-3485.  This person did not leave a message.  Must be a scam.

This is a legit IRS number. The lady discussed my refund claim with me and pointed out an error I made in filling out the return (It was not the standard 1040 income tax return). She helped me saved some bucks. Grateful.

The IRS NEVER cold-calls!

There is either a preexisting snailmail exchange, or the called person initiated a call to the IRS, and got a follow up

Surprise:
I too was once notified of an error, but it was IN WRITING.
NO COLD CALL!

Just why did you search for this number, if you knew who it was?
Are you practicing to be a shill for a NON-IRS phone call!

I claim your post is highly suspicious!

That's funny, when google searched it does not go to any IRS page at all! I agree with Slim!  If it was, it should and would have turned up the IRS page/website.

Looks like these are it, don't see this number listed and all three go to the same website! :

Hey Truth, unless you are a shill for this scam, you just been scammed out of providing your personal info to some scam artists!  IRS ALWAYS contacts you initially by mail to resolve problems, NOT telephone.
