Is a Solo 401k Right for Me?

A Solo 401k has many names such as One-Participant 401, Solo-k, Uni-k, or One-Participant k. The IRS created this retirement account with small business owners in mind. Below are some frequently asked questions that will help you determine if this plan is right for you. 

What is a Solo 401k?

A Solo 401k plan is a Qualified Retirement Plan (QRP) designed for small business owners who traditionally do not have the benefits of an employer-sponsored 401k. Business structures include a sole proprietorship, LLC, C-Corps, and S-Corp.


Who is eligible?

Self-employed individuals. In addition, their spouse (if in the business) and/or their business partners. There cannot be any full-time W-2 employees.


What is the difference between a Solo 401k and a Self Directed SEP IRA?

A Solo 401k allows for larger contributions, just like a SEP IRA, but a couple of added benefits include taking out a loan. In other words, both plans allow for significant contributions and alternative investing.


How much can I contribute to a Solo 401k?

For 2022, the maximum contribution limit is $61,000 ($67,500 if 50 or older). For 2023, the maximum contribution limit is $66,000 ($73,500 if 50 or older).  Most importantly, please have your CPA determine your eligible contribution as it is also based on your net self-employment income.


What investments can I make with a Solo 401k?

You can invest in various alternative assets with the IRA Club. For instance, real estate, private lending, life settlements, and many more. Solo 401ks can make the same investments that a Self Directed IRA can make. Therefore, a Solo 401k is an excellent option for alternative investing. 


Will I have my own checking account?

The most common account is a custodial account, where IRA Club administers the account. We send any checks/wires for investments and expenses. In addition, IRA Club will do all the bookkeeping. We have a portal where you may view the transactions and statements. You can also establish a Checkbook Solo 401(k), which allows checkbook control. Keep in mind, a checkbook account comes with a lot of responsibility. 


What is the process?

  1. Complete the Solo 401k application. Please also include a copy of your ID for verification.
  2. Sign the adoption agreement once your new Solo 401k is ready. IRA Club will email you a copy.
  3. You can easily roll over funds from an existing 401k, 403b, or TSP. Funds from an IRA are considered a “reverse rollover.” You can complete that custodian’s distribution form, and then you will re-deposit the funds into your Solo 401k. You will have 60 days from the distribution to do this without any penalties. Please note that when done correctly, there will be no taxable amount.
  4. Congratulations, you are now ready to invest using your new Solo 401k. Please complete our investment directions and provide the necessary supporting documents. Feel free to contact our investment team if you have any questions or need any help along the way.
