<prompt> Human: Hey guys, quick question. Probably not a huge deal but I thought Id ask. I recently increased my 401k contribution by 1 and actually saw an increase in my paycheck. Im only putting another 30 per pay into it now, but my federal taxes went down by about 70, so now Im seeing another 40 in my paycheck per pay. Everything else stayed the same. What is happening here, did it push me into a lower tax bracket or something? I went from 12.05 of my taxable wages to 9.64. Im mainly worried about my withholdings because I dont want to have to write another check to the IRS next year.  <response>: Withholdings changed this month because of the recent new tax law, so many peoples net pay went up.
