<prompt> Human: Hi everyoneI max out my 403b contribution annually. Same for Roth and HSA, etc. In the first week of January each year, I put in the 5500 into the Roth. I just thought of a dumb idea-- Can I effectively do something similar for the 403b and would it be beneficial? For example, put 90 of each paycheck into 403b instead of 16 or whatever Im putting in now, and then when I get to 18,500 Ill stop and go back to zero until the year is over? The taxes will all even out at the end of the year, and I have cash to live on until then other cash that hasnt gone into my stocks or is waiting to go to Roth for 2019. Is this a thing? Or am I an idiot. Thanks  <response>: Some 401k providers match by pay period, not by overall contribution, so if you had eg a 3 match and contributed 25 in one pay period, youd get a 3 match for that pay period and then 0 for all the rest. Other providers have a true up period where they put in any missing match, but it usually happens at the end of the year.I presume 403bs are similar.
