If you are under 59.5 years old and change your 72t monthly payment it will trigger penalties for all the years you used that rule. After 59.5 you can do the yearly change without penalty.
I am retiring this year at age 57 with 37 years service. I am choosing monthly payments until at least 59.5. Now, the 72t that you are referring to, is this what they mean by the equal monthly payment amounts? I see no mention of a 72t option in the withdraw choices given on the withdraw form. So, if I change the monthly amount after the first year when I am still 58, I will be hit with penalties for doing so? Probably wouldn't change anyway until 59.5 or 62 but I'd like to know if I would..
Thanks!
