Key Takeaways

• Former employer 401(k) plans almost universally prohibit participant loans after employment ends, and IRAs are legally ineligible for loans under IRC § 4975.
• A Solo 401(k) participant loan allows a qualified solopreneur to borrow up to 50% of the Solo 401(k) balance, not to exceed $50,000, repaid over a 5-year term at prime plus 1% interest (or a CD rate plus 2%).
• To qualify for a Solo 401(k), a solopreneur must have self-employment income and no non-owner, non-spouse full-time W-2 employees working for any business owned by them or their spouse.
• Rolling over a former employer plan to a My Solo 401k Financial Solo 401(k) is a tax-free direct rollover reported to the IRS via a 1099-R as a non-taxable transfer.
• Once rollover funds clear the Solo 401(k) account, the loan can be taken immediately — no waiting period and no vesting period applies.

Why Former Employer 401(k) Plans Block Participant Loans

Former employer 401(k) plans create “stranded capital” — funds that waste away in a plan the account holder can no longer fully use. Once an employee leaves a company, the former employer plan almost always strictly prohibits new participant loans. The core reason is logistical: most corporate plans collect loan repayments through paycheck deductions, and a departed employee no longer receives a paycheck.

Beyond the loan prohibition, former employer plans create additional friction for departed employees. Fees that were subsidized during active employment often increase because the employer has no incentive to continue subsidizing costs for ex-employees. Investment options may also narrow, and no new contributions are permitted since the individual no longer works for the sponsoring employer.

Why Rolling to an IRA Doesn’t Solve the Loan Problem

Rolling a former employer 401(k) into a traditional IRA is a common default choice, but it eliminates the possibility of a participant loan entirely. IRAs cannot make loans to their owners. An IRA rollover offers no path to accessing the funds through a loan.

The Fix: Roll Over to a Solo 401(k) That Allows Participant Loans

A Solo 401(k) — also called a self-employed 401(k) or individual 401(k) — is a qualified retirement plan available exclusively to self-employed individuals and small business owners with no non-owner, non-spouse full-time W-2 employees. Unlike a standard brokerage Solo 401(k) offered by Fidelity or Schwab, a Solo 401(k) established with plan documents from My Solo 401k Financial explicitly permits participant loans.

Discount Brokerage Solo 401(k) Plans Don’t Allow Loans

Schwab and Fidelity each offer their own Solo 401(k) plans, but neither plan allows 401(k) participant loans. To access the loan feature, a solopreneur must use plan documents that explicitly authorize loans — and then open a brokerage or bank account using those documents. My Solo 401k Financial provides IRS-approved plan documents that authorize loans, and helps clients open accounts at the bank or brokerage of their choice, including Fidelity and Schwab (since they will open accounts for solopreneurs who bring their own solo 401k plan documents).

Who Qualifies for a Solo 401(k)?

Solo 401(k) eligibility rests on two requirements. Meeting both unlocks access to the plan, the rollover, and the loan.

Requirement 1: Self-Employment Income

The solopreneur must report earned self-employment income on their taxes. The specific reporting line depends on the business structure:

• Sole proprietorship: net profit on line 31 of Schedule C
• S-corp or C-corp: W-2 wages paid by the business to the owner
• Partnership: income on line 14 of Schedule K-1

A formal legal entity (LLC, S-corp, C-corp) is not required. Many clients of My Solo 401k Financial operate as sole proprietors with no separate business entity.

Critically, a day job does not disqualify a solopreneur. An individual with a W-2 employer who also earns side self-employment income can establish a Solo 401(k) based on that side income, provided they meet the second requirement.

Requirement 2: No Non-Owner, Non-Spouse Full-Time W-2 Employees

The plan cannot cover any non-owner, non-spouse full-time W-2 employee working for any business owned by the solopreneur or their spouse (i.e. w-2 employee age 21 or older who works 1000 hours per year with 1 year of service or 500 hours per year for 2 consecutive years). A spouse who actively works in the business and earns their own self-employment income can also participate in the Solo 401(k), effectively doubling the household’s contributions and savings.

Solo 401(k) vs. Former Employer Plan vs. Traditional IRA: Side-by-Side

Table summary: A Solo 401(k) established with My Solo 401k Financial plan documents is the only rollover destination that unlocks participant loans, high contribution limits, alternative investments, and SECURE Act tax credits simultaneously for a qualifying solopreneur.

How the Direct Rollover Works: Step by Step

The Solo 401(k) participant loan strategy requires completing a direct rollover before the loan can be taken. My Solo 401k Financial provides hands-on support throughout the process, including deep experience transferring funds from hundreds of different institutions.

1. Confirm Solo 401(k) eligibility (self-employment income + no non-owner/non-spouse full-time W-2 employees).
2. Sign up at mysolo401k.net; plan documents are prepared within the same business day.
3. My Solo 401k Financial obtains the EIN for the plan and assists in opening a bank or brokerage account (e.g., Fidelity, Schwab, local bank) in the plan’s name.
4. Request a direct rollover from the former employer plan administrator — funds transfer by check, made payable to the Solo 401(k) plan, not the individual.
5. Deposit the check(s) into the Solo 401(k) account. Pre-tax and Roth money typically arrive as two separate checks.
6. Wait for funds to clear.
7. Submit the loan questionnaire on the My Solo 401k Financial website; loan documents are prepared within one business day.
8. Transfer loan proceeds to a personal bank account; repay per the loan schedule.

Tax Reporting of the Rollover

The former employer plan administrator reports the rollover to the IRS via a 1099-R, coded as a non-taxable direct rollover. If the administrator makes a reporting error, documentation showing that the transfer was directed as a direct rollover can be used to correct the record. The rollover itself carries no taxes and no penalties when processed correctly.

Timeline: How Long Before the Loan Is Available?

The rollover timeline depends on the former employer plan administrator’s processing speed. The typical path runs approximately two to three weeks: the administrator issues a check, the check arrives by mail, and the check clears the Solo 401(k) account. My Solo 401k Financial works in parallel to open the bank or brokerage account during this period, so the solopreneur can deposit the check immediately upon arrival. Once funds clear, the loan can be taken right away.

Solo 401(k) Participant Loan Terms: What to Expect

A Solo 401(k) participant loan from My Solo 401k Financial follows IRS rules. The loan terms are not set by a bank or credit institution.

Table summary: A Solo 401(k) participant loan carries no bank qualification requirements. The solopreneur repays the loan — including interest — back into their own retirement account.

Interest payments flow back into the Solo 401(k) account, not to a lender. The solopreneur is effectively paying interest to their own retirement plan. To learn more about the Solo 401(k) plan structure and features, the My Solo 401k Financial website provides extensive documentation.

Additional Features Unlocked by the Solo 401(k) Rollover

Beyond loan access, rolling a stranded former employer plan into a Solo 401(k) with My Solo 401k Financial opens additional wealth-building tools that are unavailable in a former employer plan or standard IRA.

Mega Backdoor Roth Solo 401(k) Contributions

My Solo 401k Financial was the first Solo 401(k) provider to offer a plan supporting the Mega Backdoor Roth strategy. For 2026, a solopreneur can contribute up to $72,000 (or more if age 50 or older) with sufficient self-employment income, with contributions ultimately directed into a Roth account. A participant loan and Mega Backdoor Roth contributions are fully compatible — they are separate transactions that do not interfere with each other.

SECURE Act Tax Credits: $500/Year for Three Years

My Solo 401k Financial was also the first Solo 401(k) provider to offer a plan that enables solopreneurs to claim SECURE Act tax credits. The plan includes an automatic contribution (EACA) feature, which unlocks a $500-per-year tax credit for three consecutive years — $1,500 in total. The solopreneur retains the right to opt out of the default contribution amount and contribute on any schedule they prefer, while still claiming the credits.

Alternative Investments and Checkbook Control

Solo 401(k) plan documents from My Solo 401k Financial authorize a wide range of alternative investments including real estate, cryptocurrency, notes, precious metals, and private equity. The plan’s checkbook control structure allows the solopreneur to act quickly on investment opportunities without waiting for a custodian to process a request. Self-directed IRAs can offer similar investments, but typically carry higher fees and slower processing times.

Investing in Real Estate Through a Solo 401(k) — An Attendee Question

Webinar attendee Michael asked how to purchase real estate using a Solo 401(k). The key rules governing Solo 401(k) real estate investing include:

• The investment must be for a pure investment purpose, not personal use.
• Real estate must be purchased from an unrelated party — not from the solopreneur or a closely related person.
• The property must be titled in the name of the Solo 401(k) plan.
• All income and expenses related to the property must flow in and out of the Solo 401(k) account.
• The solopreneur cannot personally work on the property or use it for personal purposes.
• The property must be leased or sold to an unrelated person.

Form 5500-EZ and 1099-R Support

A Form 5500-EZ is required when the Solo 401(k) plan value — including any defined benefit plan sponsored by the solopreneur — exceeds $250,000. My Solo 401k Financial provides 5500-EZ preparation at no additional charge when timely notified. The firm prepares the form in an electronic filing system, assigns it to the solopreneur for signature, and submits it to the IRS upon receipt.

A Form 1099-R is required in certain transactions, such as a Mega Backdoor Roth conversion where after-tax contributions are transferred to a Roth account. My Solo 401k Financial prepares the 1099-R and files it when timely requested through the firm’s online forms.

Definitions

Solo 401(k)

A qualified defined contribution retirement plan available exclusively to self-employed individuals and small business owners with no non-owner, non-spouse full-time W-2 employees. Also called a self-employed 401(k) or individual 401(k).

Participant Loan

A loan made from a qualified retirement plan — such as a Solo 401(k) — to a plan participant. The IRS rules cap the loan at the lesser of 50% of the vested account balance or $50,000. IRAs are prohibited from making participant loans.

Direct Rollover

A tax-free transfer of funds from one qualified retirement plan directly to another, where the payment is made payable to the receiving plan rather than to the individual. A direct rollover avoids mandatory 20% federal income tax withholding and the 60-day rollover rule that applies to indirect rollovers.

Mega Backdoor Roth

A strategy in which a Solo 401(k) participant makes voluntary after-tax contributions to the plan and then converts those contributions to a Roth account. This allows contributions beyond the standard pre-tax and Roth elective deferral limits, up to the overall 415(c) limit ($72,000 for 2026).

EACA (Eligible Automatic Contribution Arrangement)

A plan design feature that sets a default contribution percentage for participants. Under the SECURE Act, a plan that includes an EACA enables the plan sponsor to claim a $500-per-year tax credit for up to three years. Participants retain the right to opt out of the default contribution amount.

Form 5500-EZ

An IRS annual return filed by one-participant retirement plans (including Solo 401(k) plans) when the plan’s total value (including the value of any defined benefit plan) exceeds $250,000 at the end of the plan year.
