<prompt> Human: My wife and I have been living paycheck to paycheck for a while now. This year I will be getting about 4500 back from federal and 500 back from state, so It looks like I should have had an extra 400 per month if I simply adjusted my w4. I noticed my taxes withheld from my checks this year has increased, and Im afraid im going to screw this up. Any advice?I made about 50,000 in 2015We have one childI marked 2 for federal and 1 for state for 2015 on my w4.I am contributing 5 to 401k iircEdit: any advice on what I should do with the 5000? I know we need an emergency fund, but we also need about 400 worth of dental work and a mattress, but there is nothing else we really need.  <response>: Run your facts and figures through the Withholding Calculator at IRS.gov. Have your 2015 tax return and you recent paystubs handy. Revisit the calculator in October-ish to review and update your withholding, if needed.
