i just started studying for my CPA, so i'm not completely unread on the subject. but for the average person, they pay in too much, and then get the same amount back. instead of having it withheld from their check, they could have taken the money that would have been withheld, put it into an account, and saved all year. when it comes time to file, you pay exactly what you need to, and you scrape off the extra 2 or 3% on top of the money you would have gotten back instead of just receiving the straight refund. it may not seem like much, but if it happens every year for your entire life, and you keep adding into your savings anyway, that little bit extra goes a really long distance. just my two cents, agree or disagree, doesnt matter to me.
