The Secret S-Corp Strategy to Max Out Your Solo 401k in 2025

In this German‑language presentation, financial advisor Mark Kohler explains how owners of an S‑Corporation can reach the 2025 Solo 401(k) contribution limit. He starts by emphasizing the need for a reasonable compensation amount that must be taken as W‑2 wages and subject to FICA. He then shows how to split total business income into a minimum salary (e.g., $X) and the remainder as shareholder distributions. After establishing the salary, he walks through the contribution hierarchy: first fund a Roth IRA (up to the annual limit), then establish a Health Savings Account (HSA) with the appropriate family or individual contribution limits, followed by the employee salary‑deferral portion of the Solo 401(k). Finally, he adds the employer contribution, calculated as 25 % of the employee deferral amount, to reach the overall Solo 401(k) cap. Throughout, he provides placeholder dollar figures to illustrate the step‑by‑step calculation and stresses that this ordered approach maximizes tax‑advantaged retirement savings for 2025.
