Understanding the Self-employed 401(k)


You can set up a Solo 401k plan if you do not have any full time employees. If your spouse works for the business, your spouse is also eligible to save.

How it Works

A Solo 401k allows you to contribute to your retirement savings in two ways: as an employee with salary deferrals from your business income (considered your compensation), and as the employer with profit-sharing contributions.

As the Solo 401(k) plan administrator, you find, buy, sell, and manage the assets and retirement funds. It's important to segregate your plan from personal finances and business expenses. Proper recordkeeping will help you maintain the tax benefits of your solo401k. 

Monitor Contributions and Tax Treatment

Our platform allows you to monitor your contributions, broken down by type. For example pre-tax contributions are tax-deductible, but withdrawals in retirement are taxed as income.

Roth Solo 401(k) contributions are made in after-tax dollars and are not tax deductible. However, withdrawals in retirement are completely tax-free. Proper recordkeeping is important to make sure you get the tax break at retirement.

Solo 401(k) Contribution Limits

2023 Employer Contribution Limits

Total contributions to a participant’s account, not counting catch-up contributions (50 or older), may not exceed the maximum allowed for the tax year. The maximum is the lesser of 25% of an employee's compensation up to the maximum limit of $66,000 in 2023 and $69,000 in 2024. Employees and employer contributions combined may not exceed this limit.

2023 Employee Elective Deferrals/Employee Contributions

The maximum an employee can contribute to a Solo 401k from employment income is $22,500 in 2023 and $23,000 in 2024 with an additional catch-up of $7,500 if over age 50 in 2023 and $7,500 in 2024. This is all tracked and calculated by our platform.

Expand Your Portfolio with Alternative Investment Options

Investments are fully self-directed which means you choose the investments you want in your plan. These can include alternative assets not usually available through most solo (k) providers or retirement account administrators. Like in any other retirement account, all assets have a tax advantaged status. 

Here are some of the many types of investment options allowed in our self-directed Solo 401k:

  • Real estate rentals
  • Private equity
  • Limited liability corporations (LLCs) 
  • C corporations 
  • Hedge funds 
  • Startups 
  • Small businesses 
  • REITs
  • Convertible notes 
  • Land trusts
  • Stocks, bonds, and mutual funds
  • Energy, oil, and gas 
  • Tax lien certificates 
  • Precious metals
  • Cryptocurrency

Solo 401(k) Frequently Asked Questions


Can you open a 401k without an employer?

No. Regular 401k plans are employer-sponsored retirement plans. However, if you have a small business with no employees, a Solo 401(k) lets you save for retirement. You can make contributions to the plan as both employer and employee and enjoy tax benefits. 

Can I open a Solo Roth 401 k on my own?

Yes. Anyone who has a business with no employees can open a Solo Roth 401k. You can do this on your own by completing an online application.

More Frequently Asked Questions

What is a Solo 401(k)? 

A Solo 401(k) is a retirement plan for self-employed individuals or business owners with no other employees. This employer sponsored plan allows the business owner's spouse to participate in the plan. This plan allows high contribution limits. Both employee and employer contributions are allowed, helping the business and the owner lower their taxable income. 

This plan is also known as Individual 401k, Self-employed 401k, Personal 401k, and One-Participant 401k.


How do I open a Solo 401(k)? 

To open a Solo 401(k) you must have earned income from a business with no employees. You will need an EIN for the Solo (k), an EIN for the business, a checking account, and a compliant recordkeeping platform. You do not need an LLC unless that is part of your investment strategy. 

What is the contribution deadline for a Solo 401(k)? 

The contribution deadline for a Solo 401(k) is usually the employer’s tax return due date plus extensions. For corporations, employee contributions must be deposited within 7 business days after each payroll period. Contributions can be made by both the employer and employee. Since this plan is considered an owner-only plan by the IRS, the employee is also the owner.

The District of Columbia's Emancipation Day holiday sometime falls around the same time, and the tax deadline is pushed out a few days for sole proprietors and C-Corporations.
