<prompt> Human: So I messed up this year. I hit the max 401k contribution late last year, so I dropped my contribution to 0. I guess I forgot about it, and didnt notice until today, 13 of the way through the year. My living costs are substantially below my income, so I could easily increase my 401k contribution to 50 of my pretax paycheck to catch up. But the 401k administrator wont let me. They say your contribution exceeds your plan limit. The limit is 25. Does anyone know if this is a 401k rule? Or is it arbitrarily set by the administrator? Or is it arbitrarily set by the company? I suppose they might want to avoid an employee joining in December and contributing 100 to get as much matching as possible. Is there any way to make catch-up contributions for the year?  <response>: They are usually set up by the employer and administrator, I believe mine is 60. Probably not much you can do. Hopefully 25 for the rest of the year will get you there or at least close. Good luck.
