Roth TSP vs. Traditional TSP: Which Should You Choose

The core difference is when you pay taxes, not whether you pay them.

Traditional TSP takes contributions before tax, lowering your taxable income now, and taxes the withdrawals in retirement. This tends to favor people who expect to be in a lower tax bracket later than they are now.

Roth TSP takes contributions after tax, so there's no deduction now, but qualified withdrawals in retirement are entirely tax-free, growth included. This tends to favor people who expect their tax bracket to be the same or higher later, which describes a lot of junior service members early in their careers.

I personally lean heavily toward the Roth option in my own TSP, on the bet that tax rates and my own income are both more likely to be higher later than they are right now. That's a personal bet based on my own situation, not a universal rule.

A middle path exists too: splitting contributions between both, hedging against uncertainty about future tax rates instead of betting everything on one direction.

Whichever you choose, prioritize contributing enough to get the full government match first. The Roth-versus-Traditional decision matters less than the decision to actually contribute in the first place.

Always do your research to ensure the platform aligns with your financial goals and investment style.
