Solo 401k Contribution Limits
With a Solo 401k plan, the business owner is seen as the employee and employer of the business. Therefore, his or her Solo 401k contribution limits include both salary deferrals and profit sharing contribution.

Salary Deferral Contributions
In 2002, the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA) took effect and created a whole new incentive for owner-only businesses to set up Solo 401k plans. Previously, the Solo 401k was not much different from a profit-sharing plan or SEP IRA. Since the EGTRRA became effective, Solo 401k plans have been gaining popularity due to their generous contribution limits.
The Internal Revenue Code (IRC) sets the maximum amount you are allowed to contribute to your Solo 401k plan. Elective deferrals are 100% optional and are made by the business owner/employee. According to the IRS, to determine whether you have exceeded the IRC Section 402(g) limit, you must aggregate all elective deferrals contributed to all of your plans.

Profit Sharing Contributions
As an employer, the business owner can make profit sharing contributions of up to 25% of the owner’s compensation.
- If the business is a sole proprietorship or a single member LLC: The plan can receive up to 20% of the participant’s self-employment compensation.
- If the business is a multi-member LLC, partnership, corporation, or LLC with a corporation election: Solo 401k contribution limits allow profit sharing contributions of up to 25% of the total self-employment compensation.

SEP IRA vs. Solo 401k Contribution Limits
Consider the case of Tom, a 52-year-old owner of a corporation without any employees. Tom’s business pays him a salary of $100,000 a year.
With either a SEP IRA or a Solo 401k, Tom is allowed to make profit sharing contributions up to $25,000. With a Solo 401k, however, he is allowed to put an additional $30,000 into the Solo 401k as a salary deferral including catch up. A SEP IRA, on the other hand, does not allow any salary deferrals or catch up contributions.

| Profit Sharing (25% of compensation) |
$25,000 | $25,000 |
| Salary Deferral | n/a | $23,000 |
| Catch-Up Contribution | n/a | $7,500 |
