Most likely.
If there's one thing I've learned, you don't have a fair fight against our "Representative Gov". I figure with the inflation today, I'll pay it off with lesser valued dollars.
"The Internal Revenue Service today announced that interest rates will increase for the calendar quarter beginning April 1, 2022. The rates will be: 4% for underpayments;"
"Under the Internal Revenue Code, the rate of interest is determined on a quarterly basis. For taxpayers other than corporations, the overpayment and underpayment rate is the federal short-term rate plus 3 percentage points."
So expect the next penalty rate to be 4.75% or higher.
