Summary of Deadlines by Business Structure

Important Considerations
- If you miss the December 31 deadline for employee contributions, those contributions cannot be counted for that tax year, limiting your potential tax savings.
- For employer contributions, missing the tax filing deadline (including extensions) means you cannot retroactively apply those contributions to the previous tax year.
- Consult with a tax professional or financial advisor to ensure compliance with these deadlines and to maximize your retirement savings strategy effectively.
2024 Solo 401(k) Contribution Limits
The Solo 401(k) offers exceptional benefits, and understanding the contribution limits is essential for maximizing your retirement savings.
- If you are under 50 years old: You can contribute up to $23,000 for the year. This includes both employee salary deferral contributions and employer profit-sharing contributions.
- If you are 50 years old or older: You have the opportunity for catch-up contributions, allowing you to contribute up to $30,500 for the year. This catch-up amount is in addition to the regular contribution limits.
These contribution limits apply per participant. So, if you have a Solo 401(k) and your spouse is also earning income from your small business, they can also contribute the same amount to their Solo 401(k). If both you and your spouse are 50 years old or older, this means you could potentially contribute up to $76,500 together, making it a fantastic opportunity for joint retirement savings.
Solo 401(k) vs SEP IRA: Which One is Better?
Deciding between a Solo 401(k) and a SEP IRA depends on your individual circumstances and preferences. Both options have unique advantages, so let’s explore each to help you make an informed decision.
Solo 401(k):
- Higher Contribution Rate: As an employee, you can contribute up to $23,000 (plus $7,500 catch-up if eligible), and as an employer, you can contribute up to 25% of compensation, totaling up to $69,000 or $76,500 if you’re 50 or older.
- Ideal for Self-Employed: Specifically designed for self-employed individuals or small business owners without employees, making it an excellent option for those in this category.
- Tax Flexibility: You can choose between Traditional (tax-deferred) or Roth (taxed now) contributions, providing more flexibility in tax planning.
SEP IRA:
- Easy to Set Up: Simple to establish and maintain, making it suitable for small business owners who want a straightforward retirement plan for themselves and their staff.
- Employer Contributions: The employer makes all contributions, which can provide significant tax benefits for the business owner.
In conclusion, the Solo 401(k) may be more advantageous for those who are self-employed or have a small business without employees, while the SEP IRA could be a better fit for businesses with employees who want to provide retirement benefits for themselves and their staff.

Frequently Asked Questions (FAQ)
What flexibility does the SECURE 2.0 legislation provide for self-employed individuals with Solo 401(k)?
The SECURE 2.0 legislation offers considerable flexibility for self-employed individuals managing Solo 401(k) plans. One of the key benefits is the ability to establish a Solo 401(k) plan up to the tax filing deadline for the previous year. This means self-employed individuals, including sole proprietors and members of single-member LLCs, can start their plans by April 15th.
For those operating as S-Corps or partnerships, this deadline is even sooner—March 15th. Regardless of your business structure, this extended window provides ample opportunity to strategize on retirement savings contributions.
In addition to starting your plan, you can also make contributions, including Roth 401(k) and catch-up contributions, until your tax deadline. This extended timeline allows for more strategic retirement planning and tax management, enhancing your financial flexibility throughout the year.
How can Solo 401(k) owners automate their contributions?
Solo 401(k) owners can streamline their contributions by setting up automatic systems. One efficient way to do this is through automated electronic transfers via your bank account.
Steps to Automate Your Contributions:
Setting Up ACH Transfers:
Initiate an Automated Clearing House (ACH) transfer with your bank. This allows you to make regular deposits without manual initiation.
Regular Employee Contributions:
Many Solo 401(k) owners choose to automate “employee” contributions by establishing recurring ACH transfers. This approach not only saves time but also leverages the benefits of dollar-cost averaging—investing a fixed amount at regular intervals, which can reduce the impact of market volatility over time.
Periodical Employer Contributions:
While automation is excellent for employee contributions, employer contributions can be tailored based on your business performance. At the end of each quarter or year, evaluate your business income and tax strategy. After this evaluation, you can make lump-sum contributions for “employer” contributions, such as profit-sharing.
Benefits of Automated Contributions:
- Consistency: Regular, automated deposits build discipline and ensure continuous growth.
- Flexibility: Adjust your automated contribution settings as your business needs change throughout the year.
- Tax Efficiency: Align your contributions with annual tax management strategies for optimal benefits.
By setting up an automatic contribution system, Solo 401(k) owners can save time, reduce stress, and focus more on growing their business.
What considerations should be made for setting up a Solo 401(k) plan based on a non-calendar fiscal year?
When establishing a Solo 401(k) plan for a business operating on a non-calendar fiscal year, several critical considerations come into play.
Provider-Specific Deadlines:
Each 401(k) provider may have different deadlines for plan establishment. It’s essential to communicate with your chosen provider early to understand their specific requirements and timelines.
Understanding Contribution Rules:
Annual contribution rules can change, and aligning your plan with these changes is vital. Regardless of your fiscal year, staying updated on any regulatory shifts will help in managing contributions effectively.
Ease of Administrative Management:
Many businesses prefer aligning their Solo 401(k) plan with the calendar year to simplify management and ensure consistency with annual reports. This alignment can help streamline administrative tasks and reduce potential confusion during tax season.
Consideration of Business Needs:
While aligning with the calendar year has its benefits, consider your unique business cycle. Some organizations may find non-calendar fiscal year plans advantageous if it aligns better with their financial reporting or business operations.
By keeping these factors in mind, you can better navigate the complexities involved in setting up a Solo 401(k) plan that suits your business’s timing and administrative needs.
How can I maximize my Solo 401(k) Contribution?
To maximize your Solo 401(k) contribution, consider the following tips:
- Aim to contribute the maximum employee salary deferral amount ($23,000 for 2024).
- If you are 50 years old or older, take advantage of the catch-up contribution ($7,500 for 2024).
- Optimize the employer profit-sharing portion based on your business structure and income, potentially contributing between 20-25% of your net business self-employment income or W-2.
Flexible Contribution Strategies
Solo 401(k) plans offer the flexibility to make one-time contributions on any business day, free from the constraints of payroll systems. This allows you to align contributions with your cash flow and business performance.
Automated Contributions for Consistency
Consider setting up automated contributions through an electronic transfer with your bank account (ACH). By establishing regular auto-ACH for ’employee’ contributions, you can benefit from dollar-cost averaging throughout the year. This strategy not only ensures consistent investing but also helps mitigate the impact of market fluctuations.
Strategic Timing for Optimal Benefits
At the end of each quarter or year, evaluate your business income and financial goals to make additional one-time contributions or 401(k) profit-sharing contributions as needed. This strategic timing allows you to optimize your tax planning and maximize your retirement savings based on your evolving business needs.
Can I contribute to a Solo 401(k) alongside other retirement plans?
Yes, you can contribute to a Solo 401(k) alongside other retirement plans. However, keep in mind that the total combined contributions from all retirement plans must still comply with the IRS contribution limits for each plan.
What happens to my Solo 401(k) contributions if I close my business or change my employment status?
If you close your business or change your employment status, you have several options for your Solo 401(k) contributions:
- Leave the account as is and continue managing it.
- Roll it over into another retirement account.
- Withdraw the funds, but be aware of potential tax implications and early withdrawal penalties, depending on your age and circumstances.
Understanding the Solo 401(k) contribution deadline, limits, and rules is crucial for maximizing your retirement savings and tax benefits. Be sure to consult with a financial advisor or tax professional to make the best decisions for your financial situation. Remember, planning for your retirement early can significantly impact your financial security in the long run.
