I am in the 25% bracket and I do think my income will go down a bit in retirement. The reason I am going Roth 100% and pay the taxes now is two fold. The most important reason is I have 20+ years until retirement and I am confidence income rates will increase drasticly. Look at our national deficit which has tripled in 12 years. Just a decade ago the 25% bracket was the 28% bracket. Eventually it will be the 30% or higher bracket. Otherwise Social Security might be income based, some how rates will go up and I want to lock in my taxes now. The second reason it I can put more in my retirement this way. Lets say next year I move the 17000 from the traditional to the Roth account. If I am in the 25% bracket and lets say I have 5% state taxes, then I would pay $5,100 more in taxes in 2013, but I still get to put the 17,000 in my retirement. Say that 17,000 compounds at 5% for 20 years, then the value would be 45,106. Thats all my money and I can spend as I see fit, if that same 17,000 was invested in the traditional I would pay 30% taxes on the 45,106 and I would get a net value of 31,574 assuming I am in the same tax bracket. The difference I can put more real money in the Roth, because 17,000 in the Roth is worth more in 20 years than 17,000 in the traditional because of taxes. 30% of what ever is sitting in the TSP now is the goverments money when you pull it out.
If my tax bracket is lower I will live with that but if its higher than its worth it. For full disclosure, right now I have about 50% of my wife's combined retirement savings in Roth IRA investments already, I converted all of my old 401K's to Roths between 2003 and 2006. My wife contributes to a traditional retirement. When I retire I plan to have about 50% Roth and 50% traditional between the two of us. Then I can determine what I want to pull out from each type based on my brackets. If I am not near the next bracket, then I would pull out as much as possible from traditional accounts until right before then next bracket hits. Then I will take what every else I need to live on from the ROTH. I think its great tax planning.
