So, I got a notice in the mail that I missed a tax payment. I owe back taxes. Shame on me. However, the bank shows the check has cleared, stamped by the IRS. It was dismayed to see it cleared on February 17, two days after the due date but five days later than I expected they would receive it. My notice was issued March 2. I called to contest, and due to the volume of calls, they were unable to take mine. They then directed me to that ever so easily navigated IRS.gov, knowing full well time is money. Why care about interest and penalties? It’s just money. I plunge toilets and clean dog poo all week just for the joy of giving money to the IRS.
