<prompt> Human: Hi all,I got married last year, so I am filing for both myself and the wife. We both file 1 and always have since out of college.I find it weird that my refund last year is larger than this years refund with both my wife and I choosing 1... and me maintaining the same exact income.  <response>: Its called the marriage penalty. Tax brackets dont just double from the single filers to equate married filing jointly.Separately, refunds are more correlated with tax due versus tax withholding. You may have had less withholding this past year for the same income and that would cause less of a refund.If you think you need to withhold more for 2018 then you can adjust your w4 with your employer.
