<prompt> Human: I have a little over 20,000 well distributed in my TSP, military version of 401k and I cannot switch it over to the Roth TSP. A little background I am a married E5, Ive been in 6 years so 14 remaining until I get my pension and I contribute 20 of my base pay.I have no idea what my tax bracket will be after I leave the military let alone when im 65, so should I stop contributing to traditional TSP and start contributing to the Roth TSP and let the traditional TSP just continue growing?  <response>: Most people will tell you that you should be putting your money into the Roth. What is more important is that you have allocated your money on tsp.gov away from the G fund and into something else. Personally I like to follow a website called thefedtrader and allocate my money the way he does, but ymmv.When you go to pull money from your TSP at retirement you currently do not have the option to choose where the money comes from Roth vs traditional. That may have some tax implications down the road which may or may not be addressed before you retire.Source: prior military and current DoD employee.
