Why Consider Rolling Over Your 401(k), And When to Consider Avoiding It

Leaving a job or retiring is a massive life transition. With the priorities of navigating a new career path or preparing for retirement, one important financial decision sometimes gets lost in the shuffle: What should you do with your old workplace 401(k)?

You have four choices. You can leave the money where it is, cash it out, move it to your new employer’s plan, or execute a Direct Rollover into an Individual Retirement Account (IRA). While cashing out your 401(k) could trigger taxes and penalties and leaving it behind can often lead to forgotten accounts, rolling the funds into an IRA is the standard for wealth building and preservation. However, it is not universally perfect. Here is an educational breakdown of why a rollover can be a massive financial upgrade, along with the hidden drawbacks you should consider.

Part 1: The Advantages of an IRA Rollover

For the majority of savers, moving a workplace plan such as a 401(k) into a retail brokerage IRA offers immediate retirement planning benefits.

Shielding Wealth from Taxes and Penalties: A direct rollover results in a $0 immediate tax liability, allowing your entire balance to continue compounding uninterrupted. If you cash out instead before age 59½, the IRS levies a mandatory 10% early withdrawal penalty on top of ordinary income taxes, instantly wiping out up to 40% of your balance, or more.
Breaking Free from Investment Limitations: Most workplace 401(k) plans are very restrictive, generally offering a list of only 15 to 20 mutual funds. An IRA unlocks just about everything. For example, at LPL Financial, there are over 8000 mutual funds at my disposal, spanning virtually all major fund companies including a massive lineup of Vanguard and Fidelity funds. This goes alongside ETFs, individual stocks, bonds, Treasuries, and alternative assets.
Consolidating Your Financial Footprint: The average American changes jobs 12.9 times throughout their career, frequently leaving a trail of abandoned 401(k) accounts. Statements or login information often end up going missing. Consolidating these into a single IRA dashboard can eliminate administrative chaos, help prevent you from losing track of assets, and simplify calculating Required Minimum Distributions (RMDs) later in life.

💡 Advisor Note: The highest number of workplace retirement accounts I have ever consolidated for a single individual was seven. There was so much paperwork involved that the client actually physically rolled a wheeled suitcase into my office - giving a whole new meaning to a "rollover". These were actually 403(b) accounts, which fall under a similar tax code to traditional 401(k) plans.

Escaping the Threat of the Blackout Period

The easiest thing to do is to simply leave your funds sitting in your old employer's 401(k). However, doing so can leave your retirement assets at the mercy of the company's future administrative choices. Under federal law, companies can implement what is known as a Blackout Period. This is a temporary administrative freeze where participants are completely locked out of their accounts. You cannot sell stocks, change investments, or take distributions. Blackout periods typically happen when a company changes recordkeepers, alters its fund lineup, or undergoes a corporate merger. While most blackouts are routine and only last a few days to a few weeks, on rare occasions they can last for months or longer. Rolling your funds out of the company plan and into a private IRA as soon as you are eligible provides a shield against this risk:

Complete Control: Once your wealth is in a private IRA, a corporate HR department can never freeze your assets. You maintain 100% control over your liquidity, 365 days a year.
Eliminating Market Lock-In: If a severe market downturn occurs while a 401(k) is in a blackout period, you will not have any ability to make adjustments. An IRA is fully in your control and ensures you can execute trades instantly if necessary.

Real Life Case Study: Early in my career, I was working on a 401(k) rollover for a client who had left a major real estate company. Upon submitting the paperwork, we found out that the company was in an indefinite blackout period, and the funds could not be moved. It took a staggering 18 months before the client finally received a letter indicating that the blackout period had ended, allowing us to complete the rollover. A year and a half can feel agonizing to go without access to the account, but fortunately, the market had remained relatively stable during that time.

🛑 Historical Warning: The Shadow of Enron
Are 401(k) blackout periods harmless? In 2001, thousands of Enron employees lost their entire life savings because the company instituted an administrative 401(k) lockdown just as its stock went into a fraud induced freefall. While many employees were legally barred from selling their collapsing shares due to the system freeze, top executives were dumping their own unrestricted private holdings outside the plan. Moving your wealth to an IRA takes the control away from corporate third party administrators and places that control back into your own hands. The Sarbanes-Oxley Act of 2002 later implemented strict notice requirements in hopes of preventing another "Enron scenario" from happening.

In-Service Rollovers

Most savers believe you must have a "separation from service" (that's just a fancy way of saying you're leaving your employer) or completely retire to execute a rollover. However, many modern workplace plans feature a powerful, overlooked capability called an In-Service Rollover (or In-Service Distribution). Typically once you reach age 59½, if your plan allows it, you can move a portion or all of your active 401(k) balance out of the company plan and into a Traditional or Roth IRA while remaining fully employed. Executing an In-Service Rollover gives you a couple strategic advantages:

Immediate Portfolio Control: You don’t have to leave your job or wait until retirement to get away from those restrictive 401(k) investment choices. You can siphon off a chunk of your wealth today to invest in individual stocks, mutual funds or ETFs inside a private IRA under your control, all while continuing to contribute to your workplace plan.
The Roth Conversion Runway: For advanced planning, an In-Service Rollover potentially gives you a much longer runway to execute strategic Roth conversions, spreading out your future tax liability rather than facing a shorter conversion window as you approach retirement.

⚠️ Keep In Mind: Always evaluate whether converting funds while working makes sense, as your current career tax bracket may be higher than your projected retirement bracket. Additionally, double check with your HR department before initiating an In-Service distribution, as some plans may temporarily pause your employer matching contributions.

Part 2: The Disadvantages of a Rollover

Despite the benefits, rolling your 401(k) into an IRA may not always be the best move. In certain scenarios, a rollover can potentially increase your taxes, leave exposure in lawsuits, or limit your liquidity.

Loss of "Rule of 55": If you leave, quit, or are fired from your job in or after the calendar year you turn 55, you can take penalty free withdrawals from that specific, most recent 401(k). The moment you roll that money into an IRA, this option disappears. IRAs do not recognize the Rule of 55, so most people will have to wait until age 59½.
Triggering the IRS Pro-Rata Rule: High earners who make too much to contribute directly to a Roth IRA may utilize a strategy known as the Backdoor Roth IRA. If you roll a large pre-tax 401(k) balance into a Traditional IRA, the IRS aggregates all your traditional IRAs together. This triggers the pro-rata rule, turning what should be a tax free Backdoor Roth conversion into what could become an unexpected tax bill. Be aware that even if you don't roll over any funds, having any other Traditional IRAs will also be subjected to the pro-rata rule.
Downgraded Lawsuit Protection: Workplace 401(k) plans are protected by federal ERISA law, providing a nationwide shield against creditors, lawsuits, and bankruptcy judgments (though they cannot protect you from IRS tax liens or divorce QDRO settlements). However, outside of federal bankruptcy protection, IRAs are governed by state laws. While the statistical risk of a devastating lawsuit is low for most people, state protection varies from virtually full immunity to very weak protections depending on where you live, potentially placing your IRA assets on the table for seizure.

⚖️ "Reasonably Necessary" and Why Total Segregation is a Must
In some states, IRAs are only exempt from a judgment "to the extent reasonably necessary for the support of the debtor". If a judge decides you have enough other assets to survive, they can order your IRA liquidated to pay a creditor. However, a landmark California appellate ruling, McMullen v. Haycock (2007), created an essential escape hatch. If an IRA is funded exclusively by rolling over money from a fully exempt employer plan like a 401(k), those funds retain 100% of their original corporate lawsuit immunity.
To keep this protection, savers must adhere to a strict rule of total segregation. Do not commingle your accounts. If you mix standard, annual personal contributions into the same account containing your 401(k) rollover, the paper trail becomes convoluted, and a judge can strip the protective shield entirely.
The Solution: Set up an account exclusively for your 401(k) rollover funds, and open a separate Contributory IRA for your ongoing annual contributions. By keeping your Rollover IRA separate, you align your assets with the Haycock ruling.

Forfeiting the Borrowing Feature: Most active 401(k) plans allow you to borrow up to 50% of your account value up to a maximum of $50,000. While this is considered inefficient and leads to a form of double taxation, it is still available during an emergency. On the other hand, the IRS prohibits the ability to borrow from an IRA. Technically, you can do it in the form of a 60 day rollover rule, where you can withdraw money out of the IRA and then put it back without taxes or penalties. It's not actually a loan, but it can function like a short term one. There are restrictions around this. While you can "borrow" up to 100% of the account, you can do this only once per 12 month period and you must put everything back within 60 days. Whatever amount doesn't go back will be treated as a taxable distribution, and if under age 59½, there will also be a 10% penalty. Once the funds are returned, you must ensure it is correctly reported as a tax free rollover on your tax return.

Planning and Execution

Deciding what to do with a workplace retirement plan is rarely a simple, one-size-fits-all choice. For many savers, rolling a 401(k) over into an IRA provides more investment freedom, control, and simplified consolidation. But moving your money without a clear strategy can create unintended missteps. Precise, individualized planning is the key. Contact our office today to evaluate your current workplace plan. We can help answer any questions you have as well as handle the heavy lifting of any transfers on your behalf.

Pump the Brakes If You Have Company Stock

While weighing these advantages and disadvantages is crucial for cash and traditional mutual funds, there is one big exception that could change all the rules. If your 401(k) contains highly appreciated shares of your employer's stock, executing a standard rollover could permanently strip you of an often overlooked, tax saving opportunity. Before you check the standard rollover box and liquidate your account, you should definitely evaluate whether you qualify for a specialized tax strategy known as Net Unrealized Appreciation (NUA).
