Retirement often comes with a flurry of financial decisions—when to claim Social Security, whether to downsize your home, how to structure your withdrawals. One question that tends to get rushed, however, is what to do with your 401(k) once you’ve left the workforce.
Conventional wisdom says you should roll your 401(k) into an IRA as soon as you retire. But that advice doesn’t always hold up under scrutiny. In fact, staying in your 401(k) post-retirement can offer unique advantages—especially when it comes to costs, creditor protection, and tax control. This article walks through the practical reasons to consider staying put, outlines the tradeoffs, and helps you decide whether your 401(k) still fits into your long-term retirement strategy.
When you retire, your 401(k) doesn't disappear. It stops accepting new contributions (because you're no longer earning income from the sponsoring employer), but your investments remain intact, and you retain control over how they’re allocated.
As long as your balance exceeds $5,000, most plan administrators allow you to leave your funds in the plan indefinitely. That means you're not forced to act right away. The money continues to grow tax-deferred, and you maintain access to your plan’s investment menu. The IRS requires you to begin taking Required Minimum Distributions (RMDs) from your 401(k) at age 73 (as of 2025). But until then, you can keep your assets where they are—and potentially benefit from doing so.
One of the most overlooked benefits of staying in your 401(k) is cost. Large employer plans typically offer institutional share classes—versions of mutual funds and index funds that charge lower fees than what’s available to individual investors in retail IRAs.
For example, the average expense ratio for a large-cap equity fund in a 401(k) plan might be 0.06%, compared to 0.20% or more for a similar fund in an IRA. Over time, those differences add up—especially for retirees who expect to draw down their assets slowly over 20–30 years. It’s worth checking your specific plan’s fund lineup and fee disclosures. If your plan includes low-cost index funds or target-date funds with institutional pricing, that alone may justify staying.
Another quiet advantage comes from asset protection laws. Under ERISA (Employee Retirement Income Security Act), 401(k) assets are shielded from most creditor claims—even in bankruptcy. IRAs, by contrast, have weaker protections that vary by state law. In some states, IRA balances are only partially protected—or not at all—depending on the type of debt or legal claim.
If you're concerned about future lawsuits, business liabilities, or even long-term care costs, keeping money in your 401(k) might give you more peace of mind. This is especially relevant for high-net-worth retirees or former business owners who want to shield some of their nest egg from risk.
Your 401(k) continues to grow tax-deferred after retirement. That means you don’t pay taxes on dividends, capital gains, or interest income until you start taking withdrawals. This gives you flexibility—particularly if you retire before your RMDs begin.
Some retirees use this period to execute Roth conversions, shifting a portion of their pre-tax 401(k) funds into a Roth IRA in years when their income is temporarily low. Doing this while the funds are still in a 401(k) might add complexity (since most 401(k) plans don’t offer in-plan Roth conversions), but staying put delays unnecessary income realization, keeping your tax bill lower in the short term.
And once RMDs kick in at age 73, your 401(k) can serve as a predictable, taxable income stream that helps balance your broader portfolio withdrawals.
It’s true that rolling your 401(k) into an IRA gives you more control. You’ll have access to a broader array of investments, and you may be able to consolidate multiple retirement accounts under one roof. But that simplicity can come at a cost.
Many retirees are surprised by the fees, commissions, or complexity that come with retail IRAs—especially those opened through brokerage firms or independent advisors. Some of these accounts carry wrap fees, fund sales charges, or even high annual advisory costs that weren't present in your workplace plan.
More control isn't inherently better. It only helps if you're using it to match your investments to your retirement goals. Otherwise, you may simply be trading low-cost automation for unnecessary complexity.
That said, there are legitimate reasons to move your money out of a 401(k). Here are a few:
- Your old employer’s plan has limited investment options. Some plans only offer a narrow selection of funds, or charge high administrative fees.
- You want to consolidate multiple accounts. If you’ve had several jobs and multiple 401(k)s, rolling them into one IRA can make management easier.
- You plan to do Qualified Charitable Distributions (QCDs). These must come from an IRA, not a 401(k).
- You’re hiring an advisor. Some advisors only manage IRAs and require custody over assets to build a personalized strategy.
Still, these decisions are best made with a full understanding of what you’re giving up—particularly lower fees and creditor protections.
Once you turn 73, you’re required to begin taking annual withdrawals from your 401(k). These RMDs are based on your account balance and your IRS life expectancy factor. Leaving your money in a 401(k) means you’ll need to plan for these mandatory withdrawals. But the same is true of traditional IRAs. The key difference is that if you're still working for the employer sponsoring your 401(k), you may be able to delay RMDs from that account—something you can’t do with an IRA. For most retirees, the difference is moot. But if you return to part-time work or consulting and rejoin a 401(k) plan, that nuance could be useful.
If part of your retirement balance is in a Roth 401(k), staying in the plan can trigger unnecessary RMDs—unlike a Roth IRA, which has no RMDs during your lifetime.
In that case, a rollover into a Roth IRA could eliminate future required withdrawals and give you more flexibility to let the funds grow tax-free. However, you must wait five years after the first Roth contribution (not rollover) to access tax-free growth. So if you’re unsure, it’s worth reviewing your plan’s rules and your own timeline.
The question isn’t just whether your 401(k) is a good place to park your money. The better question is: How does your 401(k) fit into your overall income, tax, and legacy plan? If you have other sources of retirement income—like pensions, rental income, annuities, or taxable investments—your 401(k) might serve as a long-term drawdown asset. In that case, it makes sense to preserve low-cost compounding and defer taxes as long as possible. But if you’ll need to rely on the 401(k) for most of your monthly expenses, you might prefer the flexibility and liquidity of an IRA or taxable brokerage account.
Use the following questions to guide your next move:
1. What are my plan’s fees and investment options?
If your 401(k) offers ultra-low-cost index funds, that’s a clear advantage. If not, an IRA may provide better value.
2. When will I need the money?
If you can leave it alone for 5–10 years, the compounding benefit of staying put is higher. If you need income now, consider your withdrawal strategy and tax profile.
3. Do I need more control or flexibility?
If you want to invest in individual stocks, ETFs, or have your advisor actively manage your portfolio, an IRA may give you more freedom.
4. How does this affect my tax plan?
Consider whether staying in a 401(k) delays taxable events, helps with Roth conversion timing, or supports a lower tax bracket early in retirement.
5. What does this mean for my beneficiaries?
Some 401(k) plans don’t allow non-spouse beneficiaries to stretch withdrawals. An IRA may offer better estate flexibility.
A common mistake is rushing the rollover. Many retirees automatically transfer funds out of their 401(k) thinking it’s the only responsible choice. In reality, that reflex can lead to:
- Higher fees
- Unnecessary advisor commissions
- Lost creditor protections
- Mismatched investment strategies
The better approach is to pause, understand the unique strengths of your plan, and make a deliberate choice based on your full financial picture.
If you have a combination of retirement and non-retirement accounts, your drawdown strategy matters. You might want to spend from your taxable brokerage account first to allow your 401(k) to grow longer. Or you might convert some 401(k) funds to a Roth IRA in low-income years before RMDs begin.
The key is coordination—each account has a different tax profile, liquidity feature, and role in your portfolio. A well-sequenced withdrawal plan can improve after-tax income by tens of thousands over a 20-year horizon.
Consider a retiree who stops working at 65 but doesn’t claim Social Security until 70. During this five-year window, their taxable income may be very low. Keeping money in a 401(k) lets them execute Roth conversions at low tax rates without triggering capital gains from selling taxable assets. Meanwhile, their investment costs remain low, and their exposure is protected under ERISA. For this retiree, staying in the 401(k) is not just safe—it’s strategic.
Convenience is important—but not at the expense of control or cost. Staying in your 401(k) after retirement isn’t a sign you’re avoiding financial planning. It may mean you’ve already done the work and determined that your existing plan still serves you well. The right choice depends on your income needs, investment approach, tax outlook, and estate goals. But the takeaway is clear: You don’t have to rush to move your money. In many cases, staying put is the smart, efficient, and quietly powerful move. Let your plan work a little longer—for you.
