What is an Individual 401(k)?
An Individual 401(k)—also known as a solo 401(k)—is a retirement plan that can maximize your savings if you're self-employed or if you're a partner in a business whose only employees are the partners and their spouses.
Who can participate
Self-employed individuals and business owners with no common-law employees and their spouses who are employed by the business. The business owner can contribute both as an employer and employee. Also C corporations, S corporations, and limited liability companies (LLCs).
Employer contribution limits
- Up to 25% of compensation* not to exceed $55,000 for the 2018 tax year.
- Contributions are generally deductible as a business expense and aren't required every year. When contributions are made, however, all participants must receive the same percentage.
Employee contribution limits
- Employees may defer 100% of their compensation up to $18,500 for the 2018 tax year ($24,500 for employees age 50 or older).
- Employee contributions can be either pre-tax or after tax (Roth).
As a business owner, you can contribute both as an employer and employee. The combined amount of employer plus employee contributions can't exceed $55,000 for the 2018 tax year ($61,000 if you're age 50 or older).

Withdrawals & loans
- You can't take withdrawals until a specified event, such as reaching age 59½, termination of the plan, separation from service, or other event as identified in the plan.
- You may be allowed to take a hardship withdrawal, which may be subject to a 10% penalty if you're under age 59½.
