<prompt> Human: Hey all!I recently got a promotion and a pay raise, to the tune of 9,300.00 dollars 56.7k66k Yay! Right?My gross bi-weekly pay went from 2180.77 to 2538.47. An increase of 357.70 per paycheck, and yet my net pay only went up 175.33. From 1405.23 to 1580.56. Now I get where some of that money is going, various taxes are increasing such as SSMedicare and my 401k which are based on fixed percentages. I also know that I still have my static monthly costs on insurance.However, the one area that doesnt seem right to me is the Federal WH. It went up from 208.68 to 286.73. I certainly expected an increase especially if the new pay pushes me into a higher tax bracket, but I didnt think it would be that much more. Ive read that the increased tax amount from a higher tax bracket will only effect the income over that amount? So as I understood it if you were taxed at 20 up to 50k, and then it went to 25 at 60k; you would only be taxed the 25 on the 10k from 50-60? Or am I understanding it wrong. It seems bizarre that the federal WH went from 11.1 of my taxable income Gross-Deductions, to 13.1. Ive even just checked, and it says the 2015 Tax Brackets are 25 for 37,450 to 90,750. So shouldnt this have stayed the same based on ?Its starting to seem like I need ELI5 on taxes Ha.Any help that you all can offer so that I can wrap my head around this would be great. Thanks!  <response>: Its starting to seem like I need ELI5 on taxes Ha.If a subreddit has a wiki sometimes it pays off to look there firstAs far as your withholdings, use the IRS Withholding Calculator to see if you need to make an adjustment.
