If you have more than $1 million in your 401(k), there is no single right answer. Rolling the money into an IRA can add investment flexibility and make your accounts easier to manage, while keeping it in your employer plan can preserve low-cost institutional funds and certain withdrawal and creditor protections. At this balance, the decision is worth reviewing carefully, side by side, before you move anything.
Key takeaways • Once a balance passes $1 million, small differences in fees, taxes, and investment quality compound into meaningful dollars over a long retirement. • An IRA generally offers broader investment choices and easier coordination across accounts. A 401(k) may offer lower-cost institutional funds and stronger creditor protection. • A direct rollover from a traditional 401(k) to a traditional IRA is generally not taxable, but future withdrawals are taxed as ordinary income. • Leaving your employer in or after the year you turn 55 can allow penalty-free 401(k) withdrawals that an IRA does not (IRS rule of 55). • The right answer is often a mix: roll over some assets, keep others, and plan withdrawals and any Roth conversions around your full tax picture. |
Why does the size of your 401(k) change the decision?
Reaching $1 million or more in retirement savings is a real accomplishment. It also raises the stakes on every related decision.
At this level, small differences in investment expenses, portfolio performance, and tax treatment can have a meaningful effect on your long-term security.
Consider fees. A difference of just 0.50% in annual investment and advisory costs on a $1 million portfolio is $5,000 a year. Over a 20-year retirement, that gap compounds into a far larger number.
Lower fees are not the whole story. The quality of the investment management, the financial planning, and the service you receive all factor into the value you get.
What are the advantages of rolling a 401(k) into an IRA?
The main appeal of an IRA is flexibility.
Most employer plans offer a limited menu of mutual funds. An IRA generally opens access to a far wider range of choices, including individual stocks, bonds, exchange-traded funds, and mutual funds. That range can support a more customized strategy shaped around your retirement goals, income needs, and tolerance for risk.
An IRA can also make it easier to coordinate investments across accounts. Many investors approaching retirement hold a 401(k), a taxable brokerage account, and other savings. Managing them together supports a more consistent approach to diversification, risk, and income. Thoughtful IRA planning lets a single strategy run across the whole portfolio rather than one account at a time.
A rollover can also let an advisor review your entire portfolio as a whole rather than one account on its own.
When might keeping your 401(k) be the better choice?
Rolling into an IRA is not always the right move.
Some employer plans include institutional funds with very low expenses that can be difficult or costly to replicate in an IRA.
401(k) plans can also carry stronger federal creditor protection than IRAs, where protection depends on federal and state law.
Withdrawals matter too. Under IRS rules, investors who leave an employer during or after the year they turn 55 may take penalty-free distributions from that employer’s 401(k). This "rule of 55" generally does not apply to IRAs. For anyone planning to retire before age 59½, that difference can be significant.
The point is that the features of the specific accounts should drive the decision, because the trade-offs involved in a 401(k) rollover are rarely one-size-fits-all.
How do taxes affect a large 401(k) rollover?
A properly executed direct rollover from a traditional 401(k) to a traditional IRA generally does not create an immediate federal income tax bill.
Future withdrawals are a different matter. Distributions from traditional retirement accounts are generally taxed as ordinary income.
With a large balance, it helps to look ahead. Required minimum distributions, Social Security, Medicare premiums, and other income can interact in ways that raise your future tax bill. Large required minimum distributions, for example, can push you into a higher bracket or increase income-related Medicare premiums. A rollover by itself does not solve this, which is why coordinated tax planning matters as balances grow.
It also matters what the 401(k) holds. Appreciated company stock, Roth contributions, and after-tax contributions each call for careful handling to avoid an unintended tax result.
Should you consider a Roth conversion?
For some investors, a Roth conversion is worth weighing as part of a broader plan.
Converting traditional assets to a Roth IRA generally creates taxable income in the year you convert. In exchange, qualified Roth withdrawals are tax-free, and Roth IRAs carry no required minimum distributions during the original owner’s lifetime.
Timing is often the key. Lower-income years, such as the window between retiring and the start of required minimum distributions, can create openings to convert portions of a traditional account at potentially favorable rates. Conversions also raise current-year taxes and can affect Medicare premiums, so they deserve a careful look with qualified tax and financial professionals. If this fits your situation, our work on Roth conversion strategies walks through how the timing and the math come together.
Why does professional advice matter more at this level?
As savings grow, decisions become more connected.
Investment management, retirement income, taxes, estate planning, and charitable giving all influence how retirement assets should be handled. A rollover might add real value after you weigh costs, services, investment choices, and account protections, or it might not.
The best path may be to roll over some assets, keep others in the plan, or leave the account where it is. The goal is not to move money simply because retirement has arrived. It is to make choices that support your long-term security.

Frequently asked questions
Will I owe taxes if I roll my 401(k) into an IRA?
A direct rollover from a traditional 401(k) to a traditional IRA is generally not a taxable event. Taxes apply later, when you take distributions, which are generally taxed as ordinary income.
Can I roll over part of my 401(k) and keep the rest?
In many cases, yes. A partial rollover can capture an IRA’s flexibility for some assets while keeping low-cost funds or early-withdrawal access in the employer plan. Plan rules vary, so confirm the specifics with your plan and your advisor.
Does having more than $1 million change the rollover rules?
The rules are the same at any balance. What changes is the impact: at higher balances, fees, taxes, and investment quality carry more weight, so the analysis deserves more care.
Is an IRA always less expensive than a 401(k)?
Not always. Some large employer plans offer institutional share classes with very low costs. Compare the all-in costs and services of each option rather than assuming one is cheaper.
