<prompt> Human: Im married with no kids currently. Last year my wife and I got 2200 back from our taxes, and this year we owe 4000. I have realized that we made a lot more money this year than last year and we werent withholding enough each month to cover our new incomes. So my question is how to avoid this in the future.In June we will be having our first child and she will stop working except for some part-time hourly work. I make 114,000year and that will be our only income. I do some freelance work on the side 1099 and Im sure to save at least 30 of it for taxes. What should I set my exemption status to when she stops working? I fear that 0 wont be enough and we will owe money again next year.  <response>: I find that completing the w-4 honestly and using that number of allowances usually gets me in the right ballpark.
