Dave Ramsey and the IRS Agree This One 401(k) Misstep Could Haunt Your Retirement

Many Americans rely on their 401(k)s as their main retirement plan funding source, especially as Social Security isn't designed to cover all expenses. But both Dave Ramsey and the IRS have shared concerns about a specific trend that's putting these 401(k) funds at risk.

If not taken seriously, those dollars won't be there when seniors need them most. Learn what's causing them to sound the alarm and why near-retirees may be exposed without knowing it.

The common retirement misstep

More Americans are finding themselves in need of cash for debt, emergencies, or big purchases, and then turn to their 401(k)s to borrow against the balance. These loans are very simple, and it's easy to think, "I'm just paying myself back."

However, Dave Ramsey's stance is simple: He advises against these loans and considers them a big retirement mistake, since you can get behind on funding a proper nest egg. The IRS also treats these loans carefully and can reclassify them as taxable distributions if the rules are broken.

Why 401(k) loans look safer than they seem

Many plans do let you borrow up to a portion of your vested balance, usually with relatively low interest compared to credit cards or personal loans. It may be less hassle than dealing with a bank or credit card company, and the repayment is automatic.

So, what's the big deal about borrowing your own money — from yourself? It's so easy to borrow that it can encourage tapping into your long-term investments for things you may not really need, like home remodeling or everyday expenses. Even if you cover necessary bills, Ramsey argues that this borrowing raids your retirement fund and keeps it from growing when it needs it the most.

What really happens when you borrow

Rather than tapping into your investment to pay for things now, that money should be earning compound interest, one of the more powerful tools you have for building a nest egg. The interest plus your employer match are two ways to supercharge a retirement fund, even on a limited budget.

Ramsey recommends investing 15% of household income into tax-advantaged accounts and leaving that money alone until retirement. To risk that for today's expenses puts "future you" in jeopardy of not having enough to retire. This can happen either from you not paying back the funds entirely or by restricting growth from funds that aren't in the account to earn when they should.

The hidden cost of compounding

Let's look at a $10,000 loan from a 401(k) plan. If you borrow it at age 25 for a down payment on a home, you take decades of future growth out of the equation. Using Ramsey's preferred long‑term return assumptions, that $10,000 could have grown to several hundred thousand dollars or more by age 65.

Even with more modest returns and paying the money back sooner, there's a cost.

The double taxation problem

One other downside to borrowing from your 401(k) is how it's treated come tax time. Currently, contributions are made before taxes, growth is tax-deferred, and withdrawals are taxed in retirement as ordinary income.

When you take the money as a loan and repay it, the money used to repay is generally after-tax income from your own check. Those after-tax dollars go into the 401(k) and will be taxed again in retirement. So the repaid loan amount can effectively face two layers of taxation: once when you earn and use after‑tax dollars to repay the loan, and again when those funds are withdrawn in retirement.

How changing jobs can trigger tax trouble

If you ever leave your employer or the plan gets terminated, your 401(k) loans become payable soon after. Plans often require repayment by the due date of your tax return for that year, but some don't give you even that long.

Failure to pay by then will cause the remaining balance to be treated as a distribution, counted as taxable income, and subject to a 10% early withdrawal penalty if you're under 59 1/2. Unexpected job loss usually puts financial strain on a household, but this adds even more stress and expenses.

What the IRS says about 401(k) loans

If you don't listen to Ramsey's warnings, you still have the federal government to contend with. The IRS sets strict rules governing 401(k) loans, including borrowing limits, repayment schedules, and when a loan becomes a taxable distribution. Currently, the maximum loan is the lesser of $50,000 or 50% of your vested account balance (with some technical exceptions). Loans must be repaid at least quarterly over no more than five years, unless it's to buy a primary home.

If you fall behind on payments or borrow more than you should, the IRS treats the outstanding loan as if you took a withdrawal, and that 10% early penalty kicks in. The amount is also treated as taxable income, which can push you into a higher tax bracket and leave you with an unexpectedly higher tax bill next spring.

An IRS escape hatch (if things go wrong)

When a loan is treated as a distribution due to job loss, missed payments, or another reason, the IRS gives you one way out without penalties. You can roll over the outstanding loan balance to an IRA or other eligible retirement plan by the tax-filing deadline. This is similar to rolling over a regular 401(k) balance and keeps your tax-advantaged protections without counting it as income.

This strategy takes time and effort, though. Don't rely on it as a justification for taking an otherwise ill-advised 401(k) loan.

Bottom line

Ramsey has valid reasons for discouraging 401(k) loans, and the risks are often too large for some borrowers to bear. Between taxation, penalties, and lost growth opportunities, it's one of the more surprising financial mistakes for some. The IRS also sets strict limits on these loans; breaking any of the rules will cost you.

Building a dedicated emergency fund outside your 401(k) carries much less risk for covering unexpected expenses, and other types of loans or negotiating existing debt could offer lower‑cost relief. Whatever you choose, by treating your 401(k) with a "hands off" approach, you can protect yourself from painful tax bills and a less secure future retirement.
