2. Solo 401k Contributions Limits and Deadlines for 2024 and 2023

Solo 401k Contribution Limits 2023-24

In Solo 401(k), the business owner is the employer and the employee. Thus, contributions to a Solo 401(k) can be made in both the capacities. Contributions to a Solo 401(k) consist of two types as follows:

1. Elective deferrals known as Employee Contributions.

 

2024 2023
Maximum elective deferral $23,000 $22,500
Catch-up contribution for age 50 or older $7,500 $7,500


2. Profit sharing also known as Employer Contribution.

 

2024 2023
Maximum employer contribution $46,000 $43,500
Catch-up contribution for age 50 or older $7,500 $7,500

 

Important note: For 2024, if the business owner decides to take the full $23,000 for the elective deferral, then he/she is limited to making only $46,500 in profit-sharing contributions, thus ensuring the contribution does not exceed $69,000.

For 2023, if the business owner decides to take the full $22,500 for the elective deferral, then he/she is limited to making only $43,500 in profit-sharing contributions, thus ensuring the contribution does not exceed $66,000.
