Make sure you do your taxes on more than one tax program. Different programs will give you more or less of a refund.. I don't know why, but it's true. You can then add all of your deductions and watch your refund increase, until you add too many, then it will start to decrease. So, this is helpful to know and keep track of. Some people just write down ALL of their deductions and don't actually watch what it does to their refund.
