Rolling a 401(k) into an IRA means moving money from your employer's retirement plan into an account you control

A rollover transfers funds from a 401(k) plan — usually when you leave a job — into an Individual Retirement Account (IRA) that you open and manage yourself. The money moves directly from one institution to another, so you do not withdraw it and face taxes. The decision to roll over is not automatic; you can also leave the money in your old employer's plan, move it to a new employer's plan, or take a distribution. Each path has different costs, investment choices, and tax consequences.

The main reason people roll over is access to more investment options and lower fees. A 401(k) plan typically offers 10 to 30 mutual funds chosen by your employer. An IRA lets you invest in thousands of stocks, bonds, funds, and other securities through a brokerage firm. If your old plan charged high fees or had limited choices, a rollover can save money over time. But rolling over also means losing some protections, and the process itself has steps you must follow correctly to avoid unexpected taxes.

Key Takeaways

  • A direct rollover moves money straight from your 401(k) to an IRA without you touching it, avoiding taxes and penalties.
  • IRAs typically offer more investment choices and lower fees than 401(k) plans, but you lose creditor protection and employer matching contributions.
  • If you have a Roth 401(k), rolling into a Roth IRA keeps the tax-free growth, but rolling into a traditional IRA creates a taxable event.
  • You must complete the rollover within 60 days if you take the money yourself, or request a direct rollover to avoid a 20 percent withholding tax.
  • Before rolling over, compare your plan's fees, investment options, and any special features like loans or low-cost institutional funds.

Direct rollover versus taking the check yourself

The safest way to roll over is a direct rollover: you ask your old plan's administrator to send the money directly to the IRA custodian (the bank or brokerage holding your new IRA). You never see the check. The money moves institution to institution, and there is no tax withholding or 60-day important date to meet.

If you take the check yourself — called an indirect rollover — the plan administrator withholds 20 percent for federal taxes automatically. You then have 60 calendar days to deposit the full amount (including the withheld 20 percent) into an IRA, or the amount not deposited becomes taxable income and subject to a 10 percent early withdrawal penalty if you are under 59½. For example, if your balance is $100,000, the check arrives as $80,000 and you must deposit all $100,000 within 60 days. Most people cannot cover the $20,000 gap from their own pocket, so they end up paying taxes on it.

Request a direct rollover in writing from your plan administrator. Ask them to send the funds to the IRA custodian's address, and provide the custodian's name, your account number at that institution, and the routing information. Confirm in writing that the check will be made payable to the custodian "for the benefit of" you, not to you personally.

How fees and investment options compare

A 401(k) plan charges fees in three ways: administrative fees (record-keeping, customer service), investment fees (the expense ratios of the funds offered), and sometimes an individual service fee. Your employer may cover some of these costs. When you leave the company, you stop benefiting from any employer subsidy. An IRA at a major brokerage typically has no account maintenance fee, and you can choose from thousands of low-cost index funds with expense ratios as low as 0.03 percent per year.

However, some 401(k) plans offer institutional-class mutual funds or collective investment trusts available only to plan participants, with expense ratios lower than retail versions. If your old plan is one of these, rolling over to an IRA may actually increase your costs. Before deciding, request a fee disclosure from your plan administrator (required under Department of Labor rules) and compare the expense ratios of the funds you own to similar funds available in an IRA.

Investment choice matters most if your plan's fund lineup is narrow or misaligned with your strategy. If your plan offers only target-date funds and you want to build a custom portfolio of individual stocks or bond funds, an IRA gives you that freedom. If you are satisfied with your current investments and your plan's fees are competitive, rolling over may not be worth the effort.

Tax treatment of traditional and Roth rollovers

A traditional 401(k) can roll into a traditional IRA with no when ready tax consequence. The money was pre-tax when you contributed it, and it remains pre-tax in the IRA. You pay income tax when you withdraw it in retirement.

A Roth 401(k) can roll into a Roth IRA tax-free, preserving the tax-free growth. But if you roll a Roth 401(k) into a traditional IRA, you create a taxable event: the after-tax contributions stay after-tax, but the earnings become pre-tax, and you owe income tax on those earnings in the year of the rollover. This is rarely the right choice.

If you have both traditional and Roth money in your 401(k), you must roll each into the corresponding IRA type. You cannot combine them. Some plans allow in-service rollovers (moving money out while still employed), which can let you separate and convert Roth money before you leave the job. Check with your plan administrator about this option if you have both account types.

Creditor protection and loan access you lose

Money in a 401(k) plan is protected from creditors under federal law (ERISA). If you are sued or file for bankruptcy, creditors generally cannot touch your 401(k) balance. Money in an IRA has more limited protection: federal law protects up to $1,362,800 (as of 2023, adjusted yearly) in traditional and Roth IRAs combined, but state laws vary. Some states offer full protection; others offer none. If you work in a high-risk profession or face creditor risk, this difference matters.

A 401(k) also lets you borrow against your balance (up to 50 percent or $50,000, whichever is less) and repay it with interest. The interest goes back into your account. An IRA does not allow loans. If you think you might need to borrow from your retirement savings, keeping money in the 401(k) preserves that option. Once you roll over, you lose it.

If you leave your job at 55 or later, you can withdraw from your 401(k) penalty-free (called the "Rule of 55"). If you roll that money into an IRA, the Rule of 55 no longer applies, and withdrawals before 59½ trigger a 10 percent penalty. This is a significant reason to leave money in the old plan if you plan to retire before 59½.

When to keep money in your old 401(k) plan

Leaving your balance in your former employer's plan is a valid choice if the plan has low fees, good investment options, or special features you would lose in an IRA. Some plans offer stable value funds (similar to money market funds but with higher returns) that are not available outside the plan. If you have company stock in your plan, rolling it over may trigger capital gains tax on the appreciation; keeping it in the plan defers that tax.

You can also leave money in the old plan indefinitely (unless the balance is very small — some plans force out balances under $5,000). This gives you time to evaluate the rollover decision without rushing. If you later change jobs and want to consolidate accounts, you can roll over then.

The main downside of staying put is that you lose access to the plan's customer service once you are no longer an employee. If you have questions or need to make changes, you may face delays or be directed to an automated system. Over decades, small fee differences compound, so if the plan's costs are high, rolling over eventually makes financial sense.

Steps to complete a rollover correctly

First, open an IRA at a brokerage, bank, or mutual fund company. You will need to choose between a traditional IRA (for pre-tax money) and a Roth IRA (for after-tax money or conversions). The custodian will give you an account number and routing information.

Second, contact your old plan's administrator and request a direct rollover. Provide the new custodian's name, address, your new IRA account number, and the routing information. Ask the administrator to confirm in writing that the check will be made payable to the custodian "for the benefit of [your name]" — not to you. This language ensures the IRS treats it as a direct rollover, not a distribution.

Third, do not touch the money. If the check is mailed to you by mistake, do not deposit it into your personal account. Contact the plan administrator when ready and ask them to reissue it to the custodian. If you deposit it yourself, the IRS may treat it as a distribution, triggering withholding and penalties.

Fourth, keep copies of all correspondence. Save the rollover request, the custodian's confirmation that the funds were received, and any statements showing the transfer. You will need these for your tax records and to prove the rollover was completed within the required timeframe if the IRS ever questions it.

Frequently Asked Questions

Can I roll over a 401(k) while I am still working at the company?

Some plans allow in-service rollovers, but not all. You would need to ask your plan administrator. If allowed, you can roll over part or all of your balance to an IRA without leaving the job. This is useful if you want to separate Roth and traditional money or access more investment options while still employed.

What happens if I miss the 60-day important date for an indirect rollover?

Any amount not deposited into an IRA within 60 days is treated as a taxable distribution. You owe income tax on it, and if you are under 59½, you also owe a 10 percent early withdrawal penalty. The IRS can waive the important date in rare cases (serious illness, natural disaster, financial institution error), but you must request a waiver in writing.

Do I have to roll over my entire 401(k) balance?

No. You can roll over part of the balance and leave the rest in the old plan, or take a distribution of some money. However, if you take a distribution, it is subject to withholding and the early withdrawal penalty (if under 59½). A partial direct rollover is the cleanest way to move only what you want.

Will rolling over affect my Social Security benefits?

No. Rollovers do not count as income for Social Security purposes. However, if you take a distribution (not a rollover) and it pushes your total income above certain thresholds, it may affect how much of your Social Security is taxed. A direct rollover avoids this issue entirely.

What if my old employer went out of business or the plan was terminated?

The plan administrator is still required to distribute your balance. Contact the company's human resources or benefits department, or search the Department of Labor's plan database for contact information. If you cannot locate the plan, the Pension Benefit Guaranty Corporation (PBGC) may have records. You have the same 60-day window to roll over the distribution once you receive it.
