Depending on my refund this year I'll make some changes to my withholdings. I'm planning on paying off some debt and then maybe saving up for the ultimate toy: a new car.
If your taxes are really simple why even bother with tax software? Use a 1040 EZ. If they're a little more complicated that a 1040EZ wouldn't capture everything then go ahead and get the software but don't waste your money if you don't need to. And remember, if you do itemize, the cost of the software should be tax deductible.
