Pulse Analysis

Physicians face unique retirement planning challenges, balancing high incomes with demanding schedules. A Solo 401(k) provides the most aggressive contribution ceiling, letting high‑earning doctors defer up to $66,000 in 2026, including employee deferrals and employer profit‑sharing. This dual‑layer structure not only maximizes tax‑deferred growth but also enables intra‑plan loans, offering liquidity for practice expansions or unexpected expenses. However, the plan demands annual Form 5500 filing once assets exceed $250,000, adding compliance overhead that many solo practitioners find burdensome.

In contrast, the SEP‑IRA appeals to physicians seeking simplicity. Contributions are limited to the lesser of 25% of compensation or $66,000, which can be restrictive for those earning well above the $264,000 threshold. The SEP‑IRA’s administrative ease—no annual filing, straightforward setup—makes it attractive for early‑career doctors or those with fluctuating earnings. While it lacks loan features, its tax‑deductible contributions still reduce adjusted gross income, providing immediate fiscal relief.

The decision ultimately hinges on income level and tolerance for administrative complexity. High‑income physicians aiming to accelerate retirement savings and leverage loan options should prioritize a Solo 401(k), despite the extra paperwork. Mid‑range earners or those valuing ease of use may find the SEP‑IRA more suitable. Understanding these nuances enables physicians to align retirement strategy with practice goals, ensuring tax‑efficient wealth accumulation in a volatile economic environment.
