Need more information. What tax bracket do you expect to be in? What is your taxable income?

The max contributions are the same for pretax or Roth for the TSP. If you want to switch to maxing out Roth TSP you can put $24500 + $8000 catchup for 2026 (annual) = $1250 per pay period.


I agree with the above (putting entire $32,500 in traditional). If you were to put $24,500 into traditional and $8,000 into Roth, you would be contributing over the max limit of $24,500. The payroll system is not going to view your $8k Roth contribution as a catchup.


The payroll system will absolutely view the $8k *Roth TSP* contribution (on top of a $24,500 contribution) as catchup as long as you are 50 or older in 2026. They stopped having a separate "catchup" designation in the payroll system as of last year. As noted above, for the 50+ PP that wants to direct it all to Roth TSP, all they need to do is put $1250 per pay period into Roth TSP. ($1373 for those who are 60 to 63). Note: all agency match funds will go to the traditional TSP fund.

Finally, talk to a financial advisor if you are thinking about doing any in-plan conversions of traditional to Roth TSP, as that incurs immediate tax consequences.

I just set mine up in the TSP and I wasn't allowed to put in more than 31K total between the 2. Where are you getting the 32,500?

It does not look like we can identify funds as catchup in employee express. But I assume we could adjust how new contributions are handled in TSP, so that a portion of the $1250 goes to Roth and a potion to traditional funds.

Yes, if you are looking to have a consistent net paycheck deposit from
Pay period then choose to split between regular TSP and Roth for each pay check. Otherwise you will be taking a tax haircut at the end of the year on net paycheck from your TSP contribution.

Of course those additional income taxes may be offset if you exceed the SS threshold, salary over 184,500.

i set it up for my roth contributions to happen per-paycheck; they just created the mid-year switch-over to keep people from shooting themselves in the foot.
