TSP = 401k IMHO. Tax deferral is the main benefit of the TSP/401k. I rolled my IRA into my TSP when I retired. It should be noted that CSRS employees did not get a government matching contribution to their TSP like the folk do with FERS. (I think I am right on that, that FERS still get a match even if they don't contribute.)
I recently got a statement of my career contributions to TSP along with catch up payments. I am not sure how I will be taxed on the money when I start to draw it out. Any sharp pencil folk out there know the answer to that one? I assume they will tax more on the earned interest than the initial principal but really haven't a clue.
I retired as a state employee. The 401 and 457 are taxed at the same rate when you draw it out because zero taxes have been taken out. The only way that you can get out of paying taxes while you are still working is to open a Roth IRA. The pre taxed principal will not be taxed nor will the interest it draws. If you have a large amount in a 401, it might be a good idea to fund a Roth IRA rather than continue funding a deferred tax plan like a 401 or 457..
There is also a penalty for drawing a 401 out if you are under 59 1/2 unless it is a harship case. It is not a good idea to draw out large amounts of a 401 cause that pumps you up into a higher tax bracket. Talk to a tax adviser cause the feds might have different or preferential rules than state or private employees.
From what I have read, bastard Democrats want to require pension funds to buy gov. bonds and send them your cash starting out at a around 5% of your contributions. The gov figures that you will get a 2% return on your money. However, the SS Trust fund is broke. So, who are these jackasses trying to fool with this theft. My retirement system invests in different things and has averaged around 8% for the past 10 years. The gov. could not manage a whore house. So, this money grab will be placed in the general fund and spend and the IOU's/Gov. securities will be worth as much as what is in the SS fund. Toliet tissue.
