Back in the day, I would reach my SS limit sometime around early March. Despite my normal aversion to taxes, I always thought it was unfair and never understood the rationale, but hey, an extra few bucks a week, so.....
I would not have minded paying the tax throughout the year. At the time it was small potatoes for me and if it helped, well....
I have 17 years where I hit the cap. I didn't want 1 extra penny to go from my income into this crazy savings plan. I get WEPed and I guess my wife with get the GPO. I quit at 50 because I couldn't stand giving then 39.6% + 1.45%*2 + 0.9% on the high end. Add 12.4% on top of that would be a no brainer for quitting. I'll be taxed at 85% if I got anything out and the returns are pathetic. If I had gotten into the second bend point things would look even more bleak.
This passed last night and goes to the president for signing.
