How Does a Solo 401(k) Work?
Solo 401(k) plans, also called individual 401(k)s or one-participant 401(k)s, work similarly to a traditional 401(k) plan. The difference is that a solo 401(k) usually covers only one self-employed person, not multiple people working for the same company.
A solo 401(k) account is designed for self-employed business owners with no employees. You may also be eligible for a solo 401(k) for you and your spouse if you both are the only employees of the business you own.
With a solo 401(k), you as the business owner can make contributions as both an employee and an employer. As an employer, you can contribute up to 25% of your compensation as an employee. As an employee, you can contribute up to 100% of your compensation in elective deferrals up to the annual contribution limit.
Just like a regular 401(k), the IRS places contribution limits on solo 401(k)s. In 2023, participants can contribute up to $22,500 in elective deferrals as an employee. Total contributions to the participant’s account (employee and employer contributions together) cannot exceed $66,000.
Who Should Get a Solo 401(k)?
You might benefit from a solo 401(k) if you’re an independent contractor, sole proprietor or have an owner-only corporation. Self-employed people who choose individual 401(k)s often do so because they want a retirement plan similar to what they might get if they worked for a larger corporation.
Having a solo 401(k) can also give your business some advantages during tax time. If you own an incorporated business, you can deduct your 401(k) contributions as a business expense.
Those who own unincorporated businesses can deduct contributions from their personal income when they file their taxes.
