2025 Solo 410k Maximum Incorrect

[timjuliani]

From the forums it seems like this is an annual challenge, but the Solo 401k section is using the 2024 maximum ($76,500 with catch up) rather than the 2025 maximum of $77,500. Even when I put in the actual amounts ($23,500+$7,500+$46,500), the software says that i've entered $76,500.  This is using the update from 1/14/2026.

It's possible that the error that you are seeing has been fixed.  I entered in the amount of $70,000 for the elective deferral and $7,500 for the catch up contribution and it calculated $77,500 for the total Individual 401(k) contribution.  I tested the program a little further and entered $71,000 for the elective deferral and $7,500 for the catch-up and the program correctly determined that this was an excess contribution - and had $78,500 for the correct total contribution.
