There not making interest on it. Interest is about to go negative meaning it will cost us to save money in a financial institution, like it doesn't already.We do too and owe like $800 this year. We're just gonna roll it into what we already owe. And I told my husband to start having $25 withheld each check. He has the least amount of taxes that can be withheld because "screw them, they're not getting my money and making interest on it and then giving it back to me at the end of the year like they're doing me a favor." :sigh
