Are you saying the IRS charged your credit card for back taxes? Without your knowledge?
I know that one can use their CC to pay but I’ve never heard of that move.
I know one thing - never ignore them. As long as you are in communication and making even the smallest effort they will not get into collection and liens.
Actually, it was a debit account. Maybe that makes a big difference. But yes, I learned not to ignore them.
That was a turning point for me, to increase the amounts my employer kept to pay taxes, and to respond to all the administrative nagging. My Artful Dodger days were over from then on. I began rebuilding my credit rating too.
Face the music.
