Solo 401(k)

Self-Directed Solo 401(k)

A solo 401(k), also called an individual 401(k) or solo-k, is specifically geared for the self-employed and/or small business owners who do not have full-time employees (except themselves, their partners, or their spouses). This plan allows both employer and employee contributions: you can defer a portion of your salary into the account and have the business make a matching contribution into your plan.

Many people use a self-directed solo 401(k) so they can control their funds and choose their own investments for the plan. When you self-direct, you can use alternative assets to save for retirement—and you choose exactly what assets you want to invest in with your plan. There is a large pool of options besides stocks, bonds, and mutual funds you can choose for this purpose.

What Makes the Self-Directed Solo 401(k) so Powerful?

Self-directed solo 401(k) plans offer all the benefits of a solo 401(k) plus the ability to:

Advantages of a Solo 401(k)

These retirement plans offer many benefits for account owners:

  • You can make contributions as an employer and as an employee
  • Pre-tax savings and higher contribution limits than traditional or Roth IRAs
  • Roth and mega Roth options that allow you to maximize your employee contributions
  • Employer contributions are tax-deferred and a deduction for the business.
  • Ability to borrow personally from the plan—up to 50 percent of the account balance (for a maximum of up to $50,000)
  • Trustees can be the business owner(s) and/or spouse(s) and can manage these accounts using checkbook control
  • “C” corporations can contribute cash, property, or corporate stock and take deductions on those contributions within the limits set forth by the IRS
  • Account owners may be able to lease property owned by these accounts

Features of the Roth 401(k) Option

  • The Roth 401(k) option provides tax-free income on earnings in the account.
  • You can make after-tax employee contributions.
  • Contributions are not subject to the income limitations of a Roth IRA.
  • Roth and non-Roth contributions can be commingled within the same account—no other account type allows this.
  • You can immediately convert employer contributions to a Roth designation within your plan.

Features of the Mega Roth Option

  • You can maximize your total annual contributions by making employer + employee + mega Roth contributions.
  • Mega Roth contributions are made after-tax and must be immediately converted to the Roth component within the plan to grow tax free.
  • If the sum of your employer and employee contributions is less than the annual limit set by the IRS, the mega Roth component allows you to make up the difference in contributions for that tax year.

Who Qualifies for an Individual 401(k)? 

  • Businesses that are corporations, partnerships, LLCs, or sole proprietorships (such as self-employed individuals) and who do not have any full-time employees other than partners or their spouse.
  • To qualify for employer contributions, as an employee you must have received taxable earned income during the year.
  • If the only employees (other than the owners) of the business are under the age of 21 or do not work more than 1,000 hours/year (or 500 hours/year for a consecutive three-year period), the business owner can still use this plan.

Do you have a side business?

If you have a side-business apart from your regular job, you can use an individual 401(k) even if you have a 401(k) through your employer. A solo-k sponsored by your side business can help you max out your overall 401(k) annual contributions if you and your employer are not contributing the full amount allowed to your employer-sponsored plan.

Deadline to Open a Solo 401(k)

You have until the last day of your business’s income tax reporting year, including extensions, to open a solo-k. Depending on how your business is set up, it may benefit you to establish your plan early in the year as you can to take advantage of employee salary deferrals.

Distributions from Solo-K Plans

  • Distributions made from the tax-deferred portion of the plan are considered annual income and are subject to income tax.
  • Withdrawals from the Roth portion are treated under the same distribution rules as a Roth IRA.

If you are under the age of 59 ½, there is a 10-percent early-withdrawal penalty as well as the income tax that may be due. However, if you inherited the IRA or are disabled, there are exceptions to the withdrawal penalty. For more information, including additional exceptions, please contact your tax professional.
