Congress will have to pass these proposals in order to take effect. Chances are this is a big request with only minor changes following, but the important thing that you uncovered is that you are responsible for filling your TSP coffer.

It is the success of business in the C, S, and I funds that will help keep up with inflation and the lack or limit of COLAS. Aren't you happy that your retirement program allows you to accomplish this without the Congress or President having to get involved with COLA approvals? I will take them when they come, but without successful business all else will fail...Don't cheer to destroy it, cheer to cherish it!

Your TSP is the MOST important part of your retirement!
