Solo 401K Super Catch-up contribution

BonnieMedicare — Fri, 20 Mar 2026 16:57:53 GMT

I am 63 so should be able to use the Super Catch-up Contribution for my Solo 401K plan and contribute $34,750 in total for 2025 (before profit sharing contributions). Per Turbo Tax (as I am walking thru this section), the maximum I can defer to all my 401K plans is $31,000 and is therefore, lowering my profit sharing contribution too. Why is it not including the Super Catch-up Contribution?

Thank you!

thank you for the info but it didn't work. My Turbo Tax is up to date (according to it when i try and manually update. Still calculating this incorrectly. It's sort of corrected in that it says my total contribution can be $34,750, but then on the next page it reverts back to $31,000 and also isn't calculating profit sharing correctly.
