Those dreaded words

[truckin 79]

I have had to pay every year for several years now. Not a lot usually about 2k-3k but still hurts. I am going to start putting away more money in retirement fund and since it is taken out pre-tax that should help bring down end of the year payment. Last year the IRS wrote and said I missed calculated our gross income somehow they found an extra 6k. I still have no idea where that monies came from. Even with what they said I supposedly made did match what was in the tax table of the booklet. I still do ours on good old paper and mail in. I am wondering what is going to happen this year, owed federal 2k but state gave us back about 1k.
