Overview of Solo 401(k) and SEP IRA

The Solo 401(k), also known as an Individual 401(k), is designed for self-employed individuals with no employees other than a spouse. Key features include:

  • Higher contribution limits: Up to $69,000 (2024 limits) if you are under 50, combining employee deferral and profit-sharing contributions.
  • Roth deferral option: Contributions can be made on a pre-tax or Roth (after-tax) basis.
  • Loan options: Allows loans up to $50,000 or 50% of your account balance, whichever is lower.

 

A Simplified Employee Pension (SEP) IRA is another retirement plan option for self-employed individuals or small business owners. Key features include:

  • Simplified setup and administration: Easy to establish and maintain.
  • Contribution limits: Up to 25% of net earnings from self-employment, up to a maximum of $69,000 (2024 limits).
  • No Roth deferral option: Contributions are made on a pre-tax basis only.
 

 

Higher Contribution Limits

The Solo 401(k) offers higher contribution limits than the SEP IRA, making it an attractive option for those looking to maximize their retirement savings. Here’s how it works:

  • Employee contributions: You can contribute up to $23,000 (2024 limits) or $30,500 if you’re age 50 or older.
  • Employer contributions: Can contribute up to 25% of your net self-employment income. The total contribution limit for both employee and employer is $69,000, or $76,500 if you are 50 or older.
Advantages
  • Flexibility: You can adjust contributions annually based on your earnings and financial goals.
  • Catch-up contributions: Individuals over 50 can make additional contributions, boosting retirement savings as they approach retirement.
Example Scenario

Dr. Williams, a 45-year-old self-employed dentist, has a net self-employment income of $150,000. She can contribute $23,000 as an employee plus 25% of her income ($37,500) as an employer, totaling $60,500 in contributions in one year. Note the annual maximum is $69,000. If she increases her income, she can increase her total savings maximum in the Solo 401k.

 

The SEP IRA also has significant contribution potential but operates differently:

  • Contribution rate: You can contribute up to 25% of your net self-employment income, with a maximum of $69,000 (2024 limits).
  • Employer only: Only employer contributions are allowed; there are no employee deferrals.
Advantages
  • Simplicity: Easier to calculate and administer for those who prefer straightforward plans.
  • Cost-effectiveness: No additional filing requirements with the IRS, making it an economical choice for self-employed individuals.
Example Scenario

Dr. Brown, a 50-year-old self-employed physical therapist, earns a net self-employment income of $200,000. She can contribute 25% of her income, resulting in a $50,000 contribution to her SEP IRA. This straightforward approach simplifies her retirement planning strategy.

 

Roth Deferrals and Conversions

One of the appealing features of the Solo 401(k) is the option to make Roth deferrals. Contributions can be made on an after-tax basis, which allows for tax-free withdrawals in retirement.

Example Scenario

Dr. Carter, a 35-year-old psychologist, expects her income to increase significantly over the next decade. By contributing to a Roth Solo 401(k), she can take advantage of tax-free growth and withdrawals, which will be beneficial when she is in a higher tax bracket in retirement.

 

If your SEP IRA balance grows, you might consider converting it to a Roth IRA. This involves paying taxes on the converted amount now but allows for tax-free growth and withdrawals in the future. This can effectively be used to mimic the Roth option in a Solo 401(k).

 

When to Consider Roth Conversions
  • Lower tax bracket: When you’re in a lower tax bracket, converting to a Roth IRA can minimize tax liability.
  • Future tax planning: Allows for strategic tax planning, maximizing retirement income by potentially reducing future tax burdens.
Example Scenario

Dr. Taylor, a 40-year-old pharmacist, has accumulated a substantial balance in her SEP IRA. She plans to convert a portion to a Roth IRA in a year with lower earnings to minimize tax impact. This strategy will provide her with tax-free withdrawals in retirement, aligning with her long-term financial goals.

 

Loan Features

Solo 401(k) plans may allow for participant loans, up to $50,000 or 50% of your account balance, whichever is less. This feature can be beneficial for younger individuals who might need access to their retirement funds temporarily.

  • Accessibility: Provides a way to access funds without incurring the early withdrawal penalty.
  • Repayment to self: Loans are repaid to your account, so you are essentially paying yourself back with interest.
Risks and Considerations
  • Repayment obligation: Loans must be repaid according to plan terms. Failure to repay can result in penalties and taxes.
  • Opportunity cost: The borrowed amount could miss out on potential growth, affecting long-term savings.
Example Scenario

Dr. Green, a 32-year-old physical therapist, needs to access $30,000 for a down payment on a new home. A loan from his Solo 401(k) allows him to access these funds without the early withdrawal penalty, and he will repay the loan to his account, maintaining his retirement savings growth.

 

Practical Implications

Managing these retirement plans involves varying degrees of administrative effort. Understanding these implications can help in making an informed decision.

SEP IRA

  • Simplicity: SEP IRAs are easier to set up and have fewer administrative requirements.
