You can move old 401(k) balances into your current plan or into an IRA, but the process and rules differ by account type

When you leave a job, your 401(k) stays behind. If you've worked at multiple employers, you likely have multiple 401(k) accounts scattered across different plan administrators. Combining them into one account simplifies tracking, reduces fees, and makes it easier to manage your money as you get closer to retirement.

You have three main paths: roll your old 401(k) into your current employer's 401(k), roll it into a traditional IRA, or leave it where it is. Each path has different rules about timing, tax treatment, and what happens to loans or company stock. The choice depends on your current plan's features, the investments available to you, and whether you need to borrow against your retirement savings.

Key Takeaways

  • A 401(k) rollover moves money from an old plan to a new one without triggering when ready taxes, but you must complete the transfer within 60 days if you take the money yourself.
  • Rolling into your current employer's 401(k) keeps your money in a workplace plan and may offer lower fees, but not all plans accept rollovers.
  • Rolling into a traditional IRA gives you more investment choices and lower fees, but you lose access to the plan loan feature and certain creditor protections.
  • If you have company stock in your old 401(k), rolling it into an IRA converts it to cash, which may trigger unexpected taxes on the appreciation.
  • Leaving money in an old 401(k) is free and sometimes necessary, but you'll pay separate fees to that plan and can't add to it.

Rolling into your current employer's 401(k)

If your current employer's plan accepts rollovers—not all do—this is often the simplest path. You contact your current plan administrator and request a rollover form. You'll need the account number and contact information for your old plan. Your current plan then requests the funds directly from the old plan, and the money moves into your current account without you ever touching it.

This is called a direct rollover, and it's the safest method. No taxes are withheld, and you avoid the 60-day rule that applies if you take the money yourself. The entire balance moves over, and you can start investing it when ready in whatever funds your current plan offers.

The downside: your current plan may have higher fees than an IRA, fewer investment options, or restrictions on when you can access the money. Some plans also charge a rollover fee. Before you roll, ask your plan administrator for the fee schedule and a list of available investments. If your current plan is expensive or limited, an IRA may be the better choice.

Rolling into a traditional IRA instead

A traditional IRA accepts rollovers from any 401(k), and most people find IRAs cheaper and more flexible. You open an IRA at a brokerage—Vanguard, Fidelity, Schwab, or any other firm that offers them—and request a rollover from your old 401(k). The old plan sends the money directly to the IRA, and you can invest it in thousands of stocks, bonds, funds, and other securities.

IRAs typically charge lower annual fees than 401(k)s, and you have complete control over how your money is invested. You can also consolidate multiple old 401(k)s into a single IRA, which simplifies your financial life. The money grows tax-deferred, just as it did in the 401(k).

The trade-off is that you lose two features of a 401(k): the ability to borrow against your balance, and certain creditor protections that vary by state. If you think you might need to borrow from your retirement savings, a 401(k) rollover into your current plan keeps that option open. Also, if you have company stock in your old 401(k), rolling it into an IRA converts the shares to cash, which may trigger capital gains taxes on the appreciation—something to discuss with a tax professional before you roll.

The 60-day rule if you take the money yourself

If you ask your old plan to send the money to you directly instead of to your new account, you have 60 calendar days to deposit it into a rollover account. If you miss that important date, the IRS treats the money as a distribution, and you owe income tax on the full amount plus a 10 percent early withdrawal penalty if you're under 59½.

This rule applies only to indirect rollovers—when the check comes to you. Direct rollovers, where the money moves from plan to plan without passing through your hands, have no 60-day important date. For this reason, direct rollovers are almost always the safer choice. If you do receive a check, deposit it when ready and keep proof of the deposit date.

What happens to company stock and plan loans

If your old 401(k) holds company stock, rolling it into an IRA converts the shares to cash at the time of the rollover. This can trigger capital gains taxes on the appreciation, even though you didn't sell the stock yourself. Some people use a strategy called net unrealized appreciation (NUA) to avoid this, but it requires keeping the stock in a taxable brokerage account instead of rolling it. This is complex and worth discussing with a tax professional before you roll.

If you have an outstanding loan against your 401(k), you cannot roll the plan while the loan is active. You must either repay the loan in full or let it default. If you leave the job and don't repay the loan, the IRS treats the unpaid balance as a distribution, and you owe taxes and penalties on it. Check your plan documents for the loan repayment rules before you initiate a rollover.

Leaving money in your old 401(k)

You can leave your 401(k) with your former employer's plan indefinitely, as long as your balance is above any minimum (usually $5,000 or $10,000). You won't be able to add to it, but the money continues to grow tax-deferred. You'll pay annual fees to that plan, and you'll receive separate statements and tax forms each year.

This option makes sense if your old plan has low fees, excellent investment options, or if you have company stock you want to keep. It also makes sense temporarily, while you decide whether to roll into your current plan or an IRA. However, managing multiple accounts across different administrators is more work, and you may miss important notices about plan changes or fee increases.

Steps to complete a rollover

First, decide where the money will go: your current 401(k), a new IRA, or stay put. If you're rolling to your current plan, contact your plan administrator and ask for a rollover request form. If you're rolling to an IRA, open an account at a brokerage and ask them to initiate the rollover on your behalf—most brokerages handle this for you.

Next, gather information about your old plan: the account number, the plan administrator's name, and the current balance. You'll need this to complete the rollover request. Request a direct rollover whenever possible; this eliminates the 60-day important date and withholding taxes.

Once you submit the rollover request, the old plan typically processes it within 5 to 10 business days. The money may take another 5 to 10 days to arrive at the new account. During this time, the money is not invested—it sits in a holding account. As soon as it arrives, log into your new account and direct it into your chosen investments.

Frequently Asked Questions

Can I roll a 401(k) into an IRA if I'm still working?

Yes, if your current employer's plan allows it. Some plans permit "in-service rollovers," which let you move old 401(k) money into an IRA while you're still employed. Check with your plan administrator to see if your plan offers this feature. You cannot roll your current employer's 401(k) until you leave the job, but you can roll old 401(k)s from previous employers at any time.

What if my old 401(k) plan is being terminated?

The plan administrator will notify you and give you a important date to roll the money out or take a distribution. This important date is usually 30 to 60 days. If you don't act, the plan will distribute the money to you, and you'll owe taxes on it. Roll it out as soon as you receive notice to avoid this outcome.

Do I owe taxes when I roll a 401(k)?

No, not on the rollover itself. The money moves tax-deferred from one account to another. You only owe taxes when you withdraw the money in retirement. However, if you take a distribution and miss the 60-day important date, or if you have company stock with unrealized gains, taxes may explore. Consult a tax professional if either situation applies to you.

Can I combine multiple old 401(k)s into one IRA?

Yes. You can roll multiple 401(k)s from different employers into a single traditional IRA. Each rollover is a separate transaction, but they all go into the same account. This is one of the main advantages of rolling into an IRA—consolidation. Just make sure each rollover is a direct rollover to avoid the 60-day rule complications.

What if I have a Roth 401(k)?

Roll a Roth 401(k) into a Roth IRA, not a traditional IRA. The process is the same, but the account types must match to preserve the tax-free growth. If you roll a Roth 401(k) into a traditional IRA, you'll owe taxes on the conversion. Your old plan administrator can direct the rollover to a Roth IRA if you provide the account details.
