A Solo 401k is a retirement savings plan designed for self-employed individuals or business owners who do not have any full-time employees, other than themselves and their spouse. Also known as a one-participant 401k, it operates similarly to a traditional 401k plan, but with some distinct differences.
With a Solo 401k, you can make contributions as both the employer and the employee, allowing you to save more money for retirement compared to other self-employed retirement accounts like a SEP IRA or a SIMPLE IRA. As the employee, you can contribute up to $19,500 in 2021 and 2022, and if you are over 50 years old, you can make an additional catch-up contribution of $6,500. As the employer, you can contribute up to 25% of your net self-employment income up to a maximum of $58,000 in 2021 and 2022.
Solo 401k plans offer several benefits, including tax-deferred growth, flexible contribution options, and the ability to borrow against your retirement savings.
