Solo 401(k) FAQs

What is a Solo 401(k) Plan?

A solo 401(k) plan is not a new type of retirement plan. It is a traditional 401(k) plan covering only one employee. In general, in order to be eligible to establish a solo 401(K) plan, one must be self-employed or have a small business with no full-time employees (over 1000 hours during the year) other than a spouse or other owner(s).

 

As the name implies, the Solo 401(k) plan is an IRS approved qualified 401(k) plan designed for a self-employed individual or the sole owner-employee of a corporation. It works best when there are no other employees or a very small number of employees. 

What is a 401(k) plan?

A 401(k) plan is a special type of profit sharing plan and is named after the subsection of the Internal Revenue Code that describes it. A traditional 401(k) plan allows you to direct some of your compensation into the plan and you do not have to pay income taxes on the portion of your salary you direct into the plan until the funds are withdrawn.

What is a Roth Solo 401(k) Plan?

Employers can also establish a special type of 401(k) plan called a Roth 401(k). This plan is similar to a traditional 401(k) plan in that it allows employees to defer salary in to the plan.A roth solo 401(k) oplan is not a separate 401(k) plan but simply a roth component built into the solo 401(k) plan. The difference relates to the tax treatment. Contributions to traditional 401(k) plans are tax deductible, contributions to Roth 401(k) plans are not tax deductible. Whereas, the tax benefits for Roth 401(k)s come when you take distributions, which will be tax free so long as certain requirements are satisfied (Roth account was opened up t least 5 years and the individual is over the gae of 59/12) . The IRA Financial Group’s Solo 401(k) Plan allows for Roth type contributions.

Are there any tax credits available to reduce the cost of the Solo 401(k) Plan?

Yes. The Secure Act 2.0, which was passed in December 2022 offers a $1,500 tax credit over three years for any Solo 401(k) plan that includes the auto enrollment option. IRA Financial will assist you in filing the proper IRS documentation to receive your $1,500 tax credit which will essentially allow you to open a Solo 401(k) plan for free!

This loan has to be repaid over an amortization schedule of 5 years or less with payment frequency no greater than quarterly. The interest rate must be set at a reasonable rate of interest – generally interpreted as the Prime Interest Rate as per the Wall Street Journal. As of 5/14/18 prime rate is 4.75%. The Interest rate is fixed based on the prime rate at the time of the loan application.

 

If my spouse and I both contribute to the Solo 401(k) Plan are we both permitted to use the loan feature?

Solo 401(k) participants can borrow up to $50,000 or 50% of their account value, whichever is less, to help finance or operate their business.

The Solo 401(k) Plan is a perfect structure for any self employed business owner seeking immediate funds for their business.

  • Invest in a transaction that would otherwise be a Prohibited Transaction under Internal Revenue Code Section 4975.
  • Quick, easy, and cheap access to a $50,000 loan to be used for any purpose
What type of administrative costs and maintenance is required to maintain a Solo 401(k) Plan?

The solo 401(k) plan is easy to operate. There is generally no annual filing requirement unless your Solo 401(k) Plan exceeds $250,000 in assets, in which case you will need to file a short information return with the IRS (Form 5500-EZ). Beyond this reporting requirement, basic reporting requirement ought to be maintained. This essentially means to keep all records, receipts, contracts relating to the Solo 401(k) and its investments on file.

As a beneficiary of a Solo 401(k) Plan, what are my options for inherited plans?

If you are a beneficiary (rather than the owner) of a qualified plan and receive a distribution as a result of the owner’s death, in general you have the following options:

  • Pay ordinary income tax: If plan assets are distributed to you, then you will have to report the distribution as income on your tax return. However, if you receive a distribution from a plan you inherited, you will not have to pay an early distribution tax, even if you are younger than 591/2. The penalty is waived for inherited plans.
  • Roll over the distribution: If you inherit a qualified plan and you were the spouse of the original owner, you can roll over the distribution into a traditional or Roth IRA. However, if you inherit a retirement plan, such as a 401(k) Plan, and you were not the spouse of the original owner, then you may roll over the plan assets into a traditional IRA only if you follow certain rules. For example, you may not roll over the assets into a plan or IRA that is in your own name (you must establish a new IRA that is titled in the name of the deceased with you as the designated beneficiary).
  • Convert to a Roth IRA: A spouse that inherits a retirement plan is provided virtually all of the distribution options offered to the deceased plan participant. A Roth IRA conversion is sub ject to tax, but not the 10% early distribution penalty.
  • Use ten-year averaging.
How do the withholding tax rules work for Solo 401(k) Plan distributions?

In 1993, Congress passed a mandatory withholding law. The law requires your plan administrator to keep 20% of all qualified plan distributions to pay federal income tax before distributing the remainder to you. There are, however, some exceptions to the mandatory withholding rule. For example, amounts that are transferred directly from the trustee of your retirement plan to a trustee of another plan, or a custodian of an IRA are not subject to withholding (direct rollover).

Note: Plan administrators are required to notify you of the direct rollover option at least 30 days before the distribution is to take place.

Can I make contributions to both a SEP and a Solo 401(k) Plan?

It is good practice to not have a SEP IRA and solo 401(k) plan opened at the same time.  In fact, as per IRS Form 5305 – any employer that established a SEP IRA using the form cannot have both a SEP IRA and Solo 401(k) Plan opened at the same time.  The main reason is that both plans have employer profit sharing options.  However, if the SEP IRA was established with a bank or IRA custodian by using an individually drafted document other than IRS Form 5305, which is quite uncommon,then an employer can have a SEP IRA and Solo 401(k) plan at the same time.

 

What commonly occurs is that an employer will have a SEP IRA and make contributions to it and then open a Solo 401(K) plan and roll the SEP IRA contributions tax-free into the plan.  The employer would then close the SEP IRA and only keep the Solo 401(k) plan.

Is a Solo 401(k) Plan subject to the same UBTI rules as a Self-Directed IRA LLC?

Yes and No.

The type of income that generally could subject a Solo 401(k) to UBTI or UBIT is income generated from the following sources:

  • Income from the operations of an active trade or business – i.e. a restaurant, gas station, store, etc
  • Business income generated via a passthrough entity, such as an LLC or partnership
  • Using margin on a stock purchase

 

Unlike a Self-Directed IRA LLC, in the case of a Solo 401(k) Plan, UBTI does not apply to unrelated debt-financed income (UDFI) when using nonrecourse leverage to purchase real estate. The UDFI rules apply when a 401(k) Plan uses leverage to acquire property such as real estate. Pursuant to Internal Revenue Code Section 514(c)(9), a 401(k) Qualified Plan is not subject to the UDFI rules and, thus, the UBTI tax if nonrecourse leverage is used to acquire property such as real estate. With the UBTI tax rates at approximately 37% for 2018, the Solo 401(k) Plan offers real estate investors looking to use nonrecourse leverage in a transaction with a tax efficient solution.

 

Am I subject to UBTI Tax on Unrelated Debt Financed Income in a Solo 401(k) Plan?

No. Unlike a Self Directed IRA LLC, when a Solo 401K Plan uses nonrecourse leverage to purchase real estate that is leveraged, it is exempt from paying any Unrelated Business Taxable Income (UBTI) tax on the income or gain generated.  Whereas, when an IRA buys real estate that is leveraged with mortgage financing, it creates Unrelated Debt Financed Income (a type of Unrelated Business Taxable Income) on which taxes must be paid. A Solo 401(k) plan is exempt from UDFI pursuant to Internal Revenue Code Section 514(c)(9).

Why does the UBTI Exemption for Using Leverage in a Solo 401(K) Apply to 401(k) Plans and Not IRAs?

When Internal Revenue Code Section 514(c)(9) was enacted in 1980, it applied only to qualified pension, profit sharing, and stock bonus plans, but its scope was broadened in 1984 to include schools, colleges, and universities. The provision brings the history of Internal Revenue Code Section 514 full circle by exempting some organizations, such as 401(k) Qualified Plan, from tax on income from the very sort of leveraged real estate deals that provoked the enactment of the predecessor of Internal Revenue Code Section 514 in 1950. As per the legislative history, the only reason given in the committee reports for the exemption is that some people wanted it: “Trustees of these plans are desirous of investing in real estate for diversification and to offset inflation. Debt-financing is common in real estate investments.”

Using a Solo 401(k) Plan, what type of transactions may trigger the UBTI tax?

In general, most passive investments that your Solo 401(k) Plan might invest in are exempt from UBTI. Some examples of exempt type of income include: interest from loans, dividends, annuities, royalties, most rentals from real estate, and gains/losses from the sale of real estate.

The type of income that generally could subject a Self Directed Solo 401(k) plan to UBTI or UBIT is income generated from the following sources:

  • Income from the operations of an active trade or business – i.e. a restaurant, gas station, store, etc
  • Business income generated via a passthrough entity, such as an LLC or partnership
  • Using margin on a stock purchase
What are some of the factors the IRS or the Courts may consider when determining whether a real estate transaction may be subject to UBTI?

In general, the determination of whether a transaction or series of transaction involving a solo 401(k) plan will trigger the unrelated business axable income (UBTI) tax is based off the facts and circumstances.  The maximum tax rate for UBTI is 37% so it is important to have a good handle on whether the tax could be triggered.

 

In general, the following the IRSand the courts will look at the following factors to determine whether the retirement account transaction triggeted the UBTI tax:

  • Frequency of transactions
  • Level of continuity
  • Level of improvement
  • Intent
  • The proximity of sale to purchase
  • Purpose for which the asset was acquired
  • Personal activities of taxpayer
What is the UBTI tax rate?

Internal Revenue Code Section 511 taxes “unrelated business taxable income” (UBTI) at the rates applicable to corporations or trusts, depending on the organization’s legal characteristics. Generally, UBTI is gross income from an organization’s unrelated trades or businesses, less deductions for business expenses, losses, depreciation, and similar items directly connected therewith. A Solo 401(k) Plan subject to UBTI is taxed at the trust tax rate because an IRA is considered a trust. For 2024, a Solo 401(k) Plan subject to UBTI is taxed at the following rates:

  • $0 – $2,900: 10%
  • $2,901 – $10,550: 24%
  • $10,551 – $14,450: 35%
  • $14,451+: 37%
Are Solo 401(k) Plans protected from creditors in a bankruptcy proceeding?

Yes. Corporate retirement plans have long been safe from creditors, thanks to the Employee Retirement Income Security Act of 1974, commonly known as ERISA.

Do I need to fund the Solo 401(k) with an existing IRA or 401(k)?

No. You are not required to fund a new Solo 401(k) Plan with an existing IRA or 401(k). You can begin contributing to your new Solo 401(k) Plan once it is established.

How long does it typically take to set-up a Solo 401(k) Plan?

It generally takes one or two days to set-up the Solo 401(k) Plan.

Does the IRA Financial Solo 401(k) Plan allow for Roth Contributions?

Yes. IRA Financial Group’s Solo 401(k) Plan allows participants to elect to treat contributions under the plan that would otherwise be elective deferrals as designated Roth contributions.

 

Are the contribution rules for a Roth 401(k) the same as a Roth IRA?

The Roth subaccount of the Solo 401K Plan is a bit of a hybrid. Although it is technically a type of 401(k) plan, it has some of the features of a Roth IRA. Only after-tax salary deferral contributions may be deposited in the Roth 401(k) subaccount. No employer contributions and no pretax employee contributions are permitted. Therefore the entire account will contain only after-tax contributions from your salary plus pretax earnings on those contributions. Because the Roth 401(k) is actually just part of a regular 401(k) plan, most of the rules that apply to a regular 401(k) plan also apply to a Roth 401(k) plan, including the contribution limits.

Can a Roth 401(k) Plan exist on its own?

No. A Roth 401(k) Plan is simply an option that can be added to a traditional 401(k) Plan. A Roth 401(k) Plan cannot exist on its own.

When are Roth 401(k) distributions taxable?

Generally, distributions from a designated Roth account are excluded from gross income if they are made after the plan participant reaches the age of 591/2 and has opened and funded the Roth 401(k) account for at least 5 years.  In addition, distributions made to the plan participant’s beneficiary or estate after the employee’s death is also not taxable.

Can I convert a 401(k) Plan to a Roth 401(k) Plan?

Yes. The Small Business Jobs Act of 2010, signed by President Obama contained a little-known provision, which went to affect on Sept. 27, 2010, allowing for the conversion of a traditional 401(k) or 403(b) account to a Roth in the same plan if the plan documents include this option. IRA Financial Group’s self-directed Solo 401(k) plan documents allows for after-tax contributions and Roth conversion options.  

Can I rollover the Roth 401(k) Plan to a Roth IRA?

Yes. You are permitted to roll over your Roth 401(k) plan assets into a Roth IRA without tax or penalty. However, you must have a plan triggering event to move funds out of a 401(k) plan. In general, you need a triggering event to roll funds out of a 401k plan, which typically consists of one of the following: (i) you are over the age of 591/2, (ii) you leave your job, or (iii) the company terminates the plan. If funds are rolled directly from a 401(Ik) plan to an IRA there is no tax or penalty. 

Can I rollover a Roth IRA to a Roth 401(k) Plan?

No. Although you are permitted to roll over the assets of a Roth 401(k) plan to a Roth IRA, you may not do the reverse.

How are distributions from Roth 401(k) Plan taxed?

All distributions from Roth 401(k) plans are either qualified distributions or nonqualified distributions. If the distribution is a qualified distribution, the early distribution tax does not apply. The early distribution tax applies only to those distributions that are subject to income tax. Because all qualified distributions from Roth 401(k) Plans are tax free, they are also exempt from the early distribution tax as well. A “qualified distribution” from a Roth IRA is excluded from gross income. To be qualified, a distribution must satisfy both of the following requirements: (1) It must not occur before the fifth taxable year following the year for which a Roth IRA contribution was first made by the taxpayer or the taxpayer’s spouse and (2)

It must be made after the account owner reaches age 59 1/2 or becomes disabled, be made to the owner’s beneficiary or estate after the owner’s death or be a “qualified special purpose distribution.”

Am I required to take Distributions from my Roth 401(k) during my lifetime?

The required distribution rules that force you to begin taking money out of your retirement plans and Traditional IRAs during your lifetime also apply to Roth 401(k) Plans. The required distribution rules also force your beneficiaries to take distributions from the account after your death. Note: the rules for a Roth 401(k) Plan are different from those for a Roth IRA. If you have a Roth 401(k) plan, you must begin taking distributions from the account when you reach age 70 and 1/2, or after you retire, if that is later.

How should a Solo 401(k) Plan trustee administer a 401(k) Plan with Roth contributions?

A trustee of a Solo 401(k) Plan with a qualified Roth contribution program should establish separate accounts including only designated Roth contributions and “earnings properly allocable to the contributions,” and the plan administrator must maintain separate records for these accounts.
