<prompt> Human: Last job I made exactly 50,000 salary. Paid bi-weekly. W-2 is filed S 02 for both Federal and State allowances 75 every paycheck bi-weekly for crappy medical benefits Basic deductions 1456-ish every paycheck.Starting Oct 30th, I started the new job at 53,232. Paid every 10th and 25th. 0 out of pocket for medicaldentalvision. I contribute to retirement this time aroundlast paycheck I paid 233 and they contributed 690!. 50 Union fee on 10th day paycheck. Basic deductions 10th day paycheck 1530.22 25th day paychecks are 1465.09Im 29 years old. Ive always filed my taxes as single and independent. And every year Ive gotten back about 900-2500 by putting 2 allowances for federal and state.This new salary increase put me in a new tax bracket, Im guessing. My first plan was to increase my allowances from 2 to maybe 3 or 4. I see on the W-4 form that I put 1 for no one else claiming me as a dependent and 1 for being single and only having one job but that would only count to 2 again. I dont quality for C-G, so I cant put a 1 in those. Theres a part in the form that asks Additional amount, if any, you want withheld from each paycheck but that asks for a monetary amount which I dont know what to put without messing things up.A few of my coworkers said to get a 403B from American Fidelity because itll contribute more money towards my retirement tax free while also putting me in a lower tax bracket, which would even out my paychecks. This is where things get uncomfortable for me because its so intimidating to read through the details and know if Im doing things the right or wrong way.Would it be a good idea to put more allowances on my W-4? Do I even qualify for more allowances? What would be the best route to keeping more during the year but not end up paying out of pocket when filing my taxes?  <response>: If youre accustomed to a 500-2500 refund every year a change in your income of 6 wont change anything wildly. Tax brackets are marginal and your witholding will automatically adjust. I wouldnt overthink it.
