UPDATE: I've confirmed that the threshold of $25k over ten years below which the #IRS probably won't come after your money *** includes any interest and penalties that have accrued ***, so the math is a lot more complicated than just paying $2,500 less than you owe each year.
The interest rate the IRS charges on back taxes is variable, so if you want to get as close as possible to that $25k limit spread out over the ten years, you have to adjust how much you don't pay each year.
