The obamacare thread reminded me of this since my policy went up about $130 bucks a month.
Right now I only claim 1 exemption as does my wife. I was considering bouncing it up to 4 since we had a kid (the math on the worksheet seems to come out to 4 if you claim everything your supposed to - unless I'm reading it way wrong).
Anyone else move their exemptions around at all after having families and if so, how much more money a month did you pocket and did you end up having to pay more taxes at the end of the year instead of getting a refund?
