I always get money back every year. Married, multiple children, mortgage interest, ridiculous property taxes, all add up to a nice refund. I don't mind loaning the government tax free money through out the year. The way I see it, it's a nice bonus every February. If I calculated to not receive a refund and increase my take home pay, it would simply just fade away into other B.S. stuff like food, clothing, shoes. Like I said, it's like a nice bonus every February.
I will be purchasing a Stillen G2 CAI and Stillen CBE. Just in time for spring 2013.
