Money in the pocket today is better than than a future promise. I even took my pension early to have cash to invest over a longer period that waiting for a slightly bigger check 15 years from now. I can make more on it by investing it than I could by waiting for it to increase as part of their defined benefit plan.
When I am 62, I will file for SS and take it as soon as I can. Take the money and run. Waiting for a future payback that might not happen is not my plan. Who knows when your number is up and you won't be around to spend it?
I plan on taking my IRA distributions early too. If the numbers continue to climb too high too soon, I will be faced with much larger required distributions and having to pay income tax on the whole distribution instead of smaller ones I can take after 59.5 I pay enough taxes without adding to the pile. I already feel like I have been supporting several families in addition to mine.
