Should You Roll Over Your 401(k) to an IRA? A Conflict-Free Guide to the Decision

When you leave a job or retire, one of the first questions you'll face is what to do with your old 401(k). The default suggestion you'll hear, from a call center, a brokerage ad, or an advisor you just met, is almost always the same: roll it into an IRA. It sounds tidy. One account, one statement, more investment choices.

What rarely gets said out loud is that the person recommending the rollover often gets paid only if you do it. That single fact explains why the rollover decision is one of the most conflicted moments in personal finance, and why getting genuinely neutral advice matters more here than almost anywhere else.

Here's how to think through the decision clearly, what the research says about the costs, and why a flat fee from an advice-only financial planner is often the cleanest way to get an answer you can trust.

You Have Four Options, Not One

When you leave an employer, FINRA notes that you generally have four choices for your old 401(k):

1. Leave it in your former employer's plan, if the plan allows it.
2. Roll it into your new employer's plan, if one is available and accepts rollovers.
3. Roll it into an IRA at a brokerage or with an advisor.
4. Cash it out, which usually triggers ordinary income tax plus a 10% penalty if you're under 59 and a half.

Cashing out is almost always the worst choice. But the other three are genuinely situational, and the right answer depends on your specific plan, your fees, the investment options available, and what kind of help you want going forward. The rollover-to-IRA option gets pushed hardest precisely because it's the one that tends to generate fees for the firm recommending it.

The Conflict of Interest Hiding in Plain Sight

The numbers behind 401(k) rollovers are enormous, and so is the incentive to capture them. The U.S. Government Accountability Office reported in 2024 that conflicts of interest in rollover advice remain inadequately overseen, in part because once money lands in an IRA, the oversight that protects workplace plan participants largely disappears.

FINRA's longstanding guidance on rollovers is blunt about why: a financial professional who earns a commission or an ongoing percentage fee on your IRA has "an inherent conflict of interest" when recommending that you move money out of your 401(k) and into an account they manage. The 401(k) generates nothing for them. The IRA can generate a fee every year for the rest of your life.

The Department of Labor has tried repeatedly to close this gap. Its most recent attempt, the Retirement Security Rule, would have treated one-time rollover recommendations as fiduciary advice. As CNBC reported, the rule was stayed by federal courts and its future remains tied up in litigation. The practical takeaway for you as a consumer: you cannot assume that the person recommending a rollover is legally required to put your interests first. You have to verify it.

The Hidden Fee Trap

The conflict would matter less if rollovers were costless. They aren't. A widely cited study from The Pew Charitable Trusts found that investors generally pay higher fees in IRAs than in workplace plans, with an average difference of about 0.19 percentage points per year.

That sounds trivial. It isn't. Pew estimated that workers who rolled money into IRAs in a single year would pay roughly $45.5 billion in extra fees over the following 25 years, in aggregate. For an individual, the study modeled a 65-year-old with $250,000 who paid 0.46% inside a 401(k) versus 0.65% in an IRA. Over 25 years, the higher-fee IRA left that person with about $20,000 less.

And that gap assumes you're only comparing fund expenses. If the rollover also lands you in a 1% AUM advisory relationship, the math gets dramatically worse. A 1% annual fee on a $250,000 balance is $2,500 every year, climbing as the balance grows, on top of fund costs. Large 401(k) plans frequently offer institutional-class index funds for less than 0.10% per year, pricing that's hard for a retail IRA to beat.

When Rolling Over to an IRA Actually Makes Sense

None of this means a rollover is wrong. There are good reasons to do it:

• Your old plan has high fees or poor investment options. Some small-employer plans carry recordkeeping fees and expensive funds. If your only choices are 1%+ funds, a low-cost IRA at a major brokerage can be a clear upgrade.
• You want to consolidate scattered accounts. If you have four old 401(k)s from four jobs, a single IRA can genuinely simplify your life and your rebalancing.
• You're planning Roth conversions. A traditional IRA gives you flexibility to convert on your own schedule, which a 401(k) often doesn't.
• You need specific investments your plan doesn't offer.

The key is that these are reasons grounded in your situation, not in someone else's compensation.

When You Should Think Twice

There are equally real reasons to leave the money where it is, or move it to your new employer's plan:

• Strong institutional pricing. If your 401(k) offers index funds at 0.05% to 0.10%, that's often cheaper than what you'd pay in an IRA, especially an advised one.
• The "Rule of 55." If you leave your job in or after the year you turn 55, you can take penalty-free withdrawals from that employer's 401(k), but not from an IRA. Rolling over can forfeit that flexibility.
• Stronger creditor protection. Federal law gives 401(k) assets broad protection from creditors. IRA protection varies by state.
• Net unrealized appreciation (NUA). If you hold highly appreciated employer stock in your 401(k), a rollover can blow up a valuable tax strategy. This one alone is worth a conversation with a professional before you touch anything.
• Backdoor Roth plans. A large pre-tax IRA balance can trigger the "pro-rata rule" and complicate backdoor Roth contributions. Keeping the money in a 401(k) sidesteps that.

This is exactly the kind of decision where the details determine the outcome, and where a one-size-fits-all "just roll it over" recommendation can quietly cost you.

Why Advice-Only Fits the Rollover Decision So Well

The rollover question is a near-perfect example of why the advice-only model exists. You need an expert to compare your specific plan's fees and features against your IRA alternatives, factor in the Rule of 55, NUA, creditor protection, and your broader tax picture, and then tell you the right answer for you. What you do not need is for that expert's paycheck to depend on which answer they give.

An advice-only planner doesn't manage your money or earn a commission on the rollover, so there's no financial reason to steer you toward an IRA over your 401(k) or vice versa. They charge a flat fee for the analysis, and the recommendation is the same regardless of what you decide. That's structurally different from a traditional advisor whose ongoing revenue depends on capturing your balance.

Based on data from 97 advice-only planners on the Advice-Only Network (March 2026): one-time plan median $3,000 (range $2,000 to $4,500), hourly median $300/hr (range $250 to $360), monthly ongoing median $250/mo (range $199 to $399).

A standalone rollover analysis often fits comfortably into a few hours of an hourly planner's time, making it one of the more affordable pieces of professional advice you can buy. Compare that to a 1% advisor charging $2,500 per year on a $250,000 rollover, indefinitely, and the flat fee can pay for itself in months.

If your situation is more involved, with multiple old accounts, a pending Roth conversion strategy, or retirement income decisions on the horizon, a monthly ongoing relationship can make sense so the planner revisits the picture as your circumstances change. The point is that you choose the level of help, and you pay for advice rather than for access to your assets.

Questions to Ask Before You Roll Anything Over

Whoever you talk to, these questions cut straight to the conflict:

• Do you earn any compensation, commission, or ongoing fee if I roll my 401(k) into an IRA? If so, how much?
• Are you a CFP® professional and a fiduciary in writing, at all times, including for this rollover recommendation?
• Have you compared the total fees in my current 401(k) against the IRA you're recommending? Can I see that comparison in writing?
• Does leaving the money in my plan, or moving it to my new employer's plan, preserve any benefits I'd lose in an IRA?
• Am I holding any employer stock, and have you checked whether NUA treatment applies?

If the person can't or won't answer the first question directly, that's your answer. For a fuller screening checklist, see our guide to financial advisor red flags and the questions to ask before you hire.

The Bottom Line

Rolling a 401(k) into an IRA is sometimes the right move and sometimes a costly one. The mechanics are easy. The judgment is not, and the research from Pew and the GAO both point to the same conclusion: the advice you get is frequently shaped by how the advisor gets paid.

Before you move a dollar, get a clear-eyed comparison of your options from someone who earns the same fee no matter what you decide. For a decision this consequential, conflict-free advice is worth far more than its modest flat fee.
