If there is one financial trend that concerns me more than almost anything else today, it is the explosion of high-interest consumer debt. As a tax attorney, I spend my days helping entrepreneurs and investors legally reduce taxes and build long-term wealth. Yet I constantly meet successful business owners who are paying 20%, 25%, or even 30% interest on credit cards while simultaneously contributing to retirement accounts.

That simply does not make financial sense.

Far too many Americans are trapped in a cycle of debt. They make monthly credit card payments, but because interest rates are so high, very little of those payments actually reduce the principal balance. Others turn to payday loans or short-term cash advances that carry even higher effective interest rates, making it nearly impossible to get ahead.

Fortunately, if you are self-employed, there may be a much better solution that most financial advisors rarely discuss: the Solo 401(k) loan. Used responsibly, it can allow you to pay off expensive credit card debt, eliminate payday loans, improve your cash flow, and unlike borrowing from a bank, the interest you pay goes back into your own retirement account instead of enriching a credit card company.

America’s Credit Card Debt Problem

Americans owe nearly $1.25 trillion on their credit cards, while average credit card interest rates have climbed above 20%, with many consumers paying 24% or even 30%. Millions more rely on payday loans and other forms of emergency financing that can carry annualized rates approaching 400%. The result is staggering: Americans now pay well over $250 billion each year in credit card interest and fees, money that goes directly to banks and credit card companies instead of helping families build wealth.

The problem is not borrowing money itself. Businesses borrow every day to grow, and consumers occasionally need access to credit for unexpected expenses. The real problem is the cost of that debt. At rates of 20% to 30%, borrowers can spend years making payments while barely reducing the principal balance. A $30,000 credit card balance at 24% generates roughly $7,200 of interest every year if the balance remains outstanding. Instead of building wealth, you are effectively paying thousands of dollars annually to a credit card company simply for the privilege of borrowing money.

Every dollar paid in interest to a credit card company is a dollar that can never be invested, never earn compound returns, and never help fund your retirement. Over decades, that lost opportunity can amount to hundreds of thousands of dollars.

The Solo 401(k): One of the Most Powerful Retirement Plans Ever Created

The Solo 401(k) is available to almost anyone with self-employment income, whether you operate a full-time business, own an LLC, work as an independent contractor, earn consulting income, or have a profitable side hustle. To establish one, you must have self-employment income and generally cannot employ full-time employees other than yourself and, if applicable, your spouse.

For 2026, participants can generally contribute up to $72,000, with even higher limits available for those eligible for catch-up contributions. Contributions may be made on a pre-tax basis, reducing current taxable income, or as Roth contributions, allowing investments to grow completely tax-free if the distribution requirements are satisfied.

A properly designed Solo 401(k) also offers checkbook control, meaning you serve as trustee of your own plan and can write checks or initiate wires directly from the plan’s bank account without waiting for custodian approval on every transaction. That flexibility opens the door to far more than traditional stocks and mutual funds, including cryptocurrency, rental real estate, private equity, venture capital, private lending, precious metals, and many other alternative assets.

The plan also enjoys excellent creditor protection under both federal and state law, and when purchasing real estate with a nonrecourse loan, a Solo 401(k) is generally exempt from the Unrelated Debt-Financed Income tax that typically applies to leveraged real estate owned by an IRA.

Despite all of these benefits, there is one feature that receives far too little attention: the ability to borrow from your own retirement account.

How the Solo 401(k) Loan Works

Unlike an IRA, a Solo 401(k) can generally allow participants to borrow from their retirement savings without triggering taxes or penalties, provided the loan satisfies the requirements of the Internal Revenue Code and the terms of the plan document.

Generally, a Solo 401(k) participant may borrow the lesser of $50,000 or 50% of the vested account balance. If your balance is $60,000, you can borrow up to $30,000. If your balance is $100,000 or more, you can generally borrow the maximum $50,000.

There is no credit check. Your credit score does not matter, your debt-to-income ratio does not matter, and there is no lengthy underwriting process. As long as your plan permits participant loans and you satisfy the IRS requirements, you can generally access the funds quickly.

The proceeds can be used for virtually any purpose: paying off high-interest credit card balances, eliminating payday loans, covering unexpected medical expenses, making home repairs, funding college tuition, consolidating debt, covering temporary business expenses, or simply providing short-term liquidity during a difficult period.

Repayment is generally required over no more than five years through substantially level installments of principal and interest, unless the loan is used to purchase a primary residence, in which case a longer repayment period may be permitted.

Now here is the part that changes the economics entirely. When you borrow from a bank, every interest payment benefits the bank. When you borrow from a Solo 401(k), the interest you pay is credited back to your own retirement account. You are paying yourself instead of paying a lender.

Using the current Prime Rate as an example, if your plan carries a 6.75% interest rate and you borrow $10,000 to eliminate credit card debt charging 24%, you are paying approximately $675 in annual interest rather than $2,400, and every dollar of that interest flows back into your own retirement account.

One important tradeoff: while the money is out on loan, it is no longer invested in the market. If the market performs exceptionally well during that period, you may miss some investment gains. That is why I generally recommend using a Solo 401(k) loan only when it serves a meaningful financial purpose, such as eliminating high-interest debt, not for unnecessary spending.

Case Study 1: Eliminating $40,000 of Credit Card Debt

John is a 45-year-old self-employed marketing consultant who has accumulated $200,000 in his Solo 401(k). After several slow business months, he relied on credit cards and now carries $40,000 in debt at 24% interest.

He has two options.

If John continues making credit card payments, his $40,000 balance generates approximately $9,600 of interest every year at 24%. Over five years of disciplined repayment, his monthly payment would be approximately $1,150 and he would pay nearly $29,000 in total interest directly to the credit card company.

Instead, John borrows $40,000 from his Solo 401(k) at 6.75% and immediately pays off every credit card balance. Repaid over five years, his monthly payment drops to approximately $787 and he pays approximately $7,200 in total interest, every dollar of which goes back into his own retirement account.

By using the Solo 401(k) loan, John lowers his monthly payment by more than $350, saves roughly $22,000 in interest, and redirects approximately $7,200 back into his own retirement account instead of a bank’s pocket.

Case Study 2: Eliminating $13,000 of Credit Card Debt

Sarah is a self-employed consultant with $13,000 of credit card debt at 24% interest and more than $26,000 in her Solo 401(k), making her eligible to borrow up to $13,000.

Rather than continuing to pay 24% interest, Sarah borrows $13,000 from her Solo 401(k) at 6.75% and immediately pays off her balance. Repaid over five years, her monthly payment is approximately $256 and she pays approximately $2,340 in total interest back into her own account.

If Sarah had kept the credit card balance and committed to paying it off over the same five years, her monthly payment would have been approximately $374 and she would have paid roughly $9,450 in interest to the credit card company.

By using the Solo 401(k) loan, Sarah reduces her monthly payment by approximately $118, saves about $7,100 in borrowing costs, and redirects more than $2,300 of interest back into her own retirement account.

The Same Strategy Works for Payday Loans

The benefits become even more dramatic when payday loans are involved. Payday loans can carry annualized interest rates that exceed several hundred percent, and many borrowers repay one only to immediately take out another, creating a cycle that is extremely difficult to escape.

Consider a self-employed graphic designer who has built a Solo 401(k) worth $120,000 and finds herself with $15,000 in payday loans and high-interest cash advances after unexpected medical bills and several slow business months. Rather than continuing to refinance those loans at exorbitant rates, she borrows $15,000 from her Solo 401(k), immediately eliminates every payday loan, and begins repaying herself at a fraction of the cost. The payday loan cycle ends, her borrowing cost drops dramatically, her monthly payments become manageable, and every interest payment now rebuilds her retirement savings instead of going to a lender.

An Important Word of Caution

The Solo 401(k) loan is not a tool for financing vacations, luxury purchases, or unnecessary spending. The purpose of this strategy is to replace very expensive debt with far less expensive debt while allowing you to repay yourself rather than a financial institution.

Used responsibly, it can help business owners regain control of their finances, improve cash flow, reduce interest expense, and continue building long-term retirement wealth. But discipline is essential. If you eliminate your credit card balances only to run them up again, you have simply created a new financial problem. Used as a one-time tool to break free from high-interest debt with a commitment to responsible borrowing going forward, it can be one of the smartest financial decisions a self-employed individual ever makes.

Final Thoughts

The Solo 401(k) is one of the most powerful retirement plans available to self-employed Americans. It offers high contribution limits, valuable tax deductions, Roth contribution options, checkbook control, access to alternative investments, and the unique ability to borrow from your retirement savings without creating a taxable distribution when the loan is properly structured and repaid. No IRA offers that combination.

If you are self-employed and carrying high-interest credit card debt, do not assume your only choices are expensive personal loans, debt settlement companies, or payday lenders. The Solo 401(k) loan may be a far better alternative, one where you borrow from yourself at a fraction of the cost and repay the interest back into your own retirement account.

At IRA Financial, we have helped tens of thousands of entrepreneurs establish Solo 401(k) plans specifically designed to maximize the benefits Congress intended, including participant loans, Roth contributions, checkbook control, and the ability to invest in virtually any asset permitted under the Internal Revenue Code. If you want to understand whether a Solo 401(k) loan could work for your situation, our team of in-house tax specialists is available for a free consultation.

The smartest way to regain control of your finances may not be borrowing from someone else at all. It may be borrowing from yourself.
