<prompt> Human: My wife and I both still claim single and 0 exemptions on our W4s. Were now married and have a child.Im thinking of having us both change to married with 2 exemptions, which should amount to around 600 more per month in net pay. In a perfect world, should this make our year end tax filing wash out? Weve always gotten a big return every year, but Im thinking now the money could be better spent or invested during the year instead of waiting for that payout. I just dont want to end up owing a ton at the end of the year.I know each situation is different, but we lead a pretty vanilla financial life. Nothing much going on outside of my 350month in student loans. So Im just looking for a generic answer that applies to the majority.Thanks.  <response>: Use the IRS withholding calculator.
