re: Income Tax Issue/Question

My argument is that I mailed a check for the originally owed income tax. I thought it went through and I was in good standing. I filed the last two years and received state and federal refunds with no notice of any issue.

I had changed my address so it's possible they were sending notices to my previous address, but why wouldn't my address have been updated after I filed for my past two refunds under my new address.

As I said earlier, If by some chance they did not receive the income tax payment I sent two years ago I'm ok with paying what I originally owed. I just don't want to be hit with penalties when I had no idea there was an issue.
