<prompt> Human: We are a family of 3 with 1 on the way. We both work but I am very part time as an independent contractor. Last year I had to pay about 1000 for SS taxwhich our return more than covered. My husband works a standard W2 job and we are trying to get as much of our money now to prepare for the new baby expenses. We dont want to owe money at the end of the year but we want as much back now as possible.  <response>: use the IRS Withholding Calculator to make any necessary adjustments to your husbands W4.
