What to Do With Your Old 401(k): Five Options Explained

Changing jobs or preparing for retirement often leaves you with an important decision: what should you do with your old 401(k)? You may be able to keep the money where it is, move it to a new workplace plan, roll it into an IRA, or withdraw it. Each path has different implications for fees, investment choices, taxes, and access to your savings. There is no single answer that works for everyone. Before making a move, it helps to understand the five approaches described below and how they fit into your broader retirement plan.

1. Leave Your 401(k) With Your Former Employer

If your former employer’s plan permits it, you may be able to leave your existing retirement savings in the plan after you change jobs. Your money can remain invested without an immediate rollover or taxable distribution. This may be worth considering if the plan offers investments you like, reasonable fees, or features you would lose by transferring the account. Certain participants who separate from service during or after the calendar year they turn 55 may also qualify for an exception to the 10% additional tax on early withdrawals from that employer plan. That exception generally does not carry over to an IRA. The trade-off is that you may have another account to monitor, and your former employer controls the plan’s menu and rules. Some plans also require smaller balances to be moved out. Check the plan documents before assuming you can leave the account in place indefinitely.

2. Roll Your Old 401(k) Into a New Employer’s Plan

If you have started a new job, the new employer’s 401(k) may accept rollovers from a prior plan. Moving eligible funds into the new plan can make retirement accounts easier to track while preserving tax-deferred treatment when the rollover is handled correctly. However, not every employer plan accepts incoming rollovers. Compare investment options, account and investment fees, distribution provisions, and the services offered by both plans before deciding. A new plan is not automatically a better fit simply because it is more convenient.

3. Cash Out Your Old 401(k)

Taking a cash distribution gives you immediate access to the funds, but it can also reduce the money set aside for retirement. The taxable portion of a traditional 401(k) withdrawal generally becomes ordinary income in the year received. If you are younger than 59½, a 10% additional early-distribution tax may apply unless you qualify for an exception. An eligible rollover distribution paid directly to you is generally subject to mandatory 20% federal income tax withholding. Withholding is a prepayment of taxes, not necessarily your final tax liability. Because of these potential consequences, it is important to evaluate other sources of cash and the long-term impact before withdrawing retirement savings.

4. Complete an Indirect IRA Rollover

With an indirect rollover, the plan sends the eligible distribution to you, and you then deposit it into an eligible IRA or retirement plan. You generally have 60 days from receiving the funds to complete the rollover. If you miss the deadline, the amount not successfully rolled over may become taxable and could be subject to an additional early-distribution tax. The 20% mandatory withholding rule also matters here. For example, if you receive a $10,000 eligible distribution from a traditional 401(k), the plan generally withholds $2,000 and sends you $8,000. To roll over the entire $10,000, you would need to replace the withheld $2,000 from other funds within the deadline. Rolling over only $8,000 would generally leave the $2,000 withheld amount taxable. An indirect rollover can involve more steps, deadlines, and potential complications than a direct rollover. Review the rules carefully before requesting a check payable to yourself.

5. Roll Your 401(k) Directly Into an IRA

In a direct rollover, the old plan sends eligible retirement funds straight to the receiving IRA, or issues a check payable to the IRA custodian for your benefit. Because the distribution is not paid to you, the mandatory 20% withholding generally does not apply. Moving pre-tax 401(k) money into a traditional IRA through a properly completed direct rollover generally does not create current income tax. An IRA may offer a different range of investments and account-management choices. But it may also have different fees, creditor protections, early-withdrawal rules, and advice-related costs. A rollover is not necessarily preferable to retaining employer-plan assets. If your account includes Roth money, after-tax contributions, employer stock, or an outstanding loan, additional rules may affect your decision.

How to Compare Your Old 401(k) Options

Rather than focusing only on where your account will be held, consider how each choice supports your retirement goals. Review the total cost of the account, available investments, access to funds before retirement, creditor protections, required distributions, and whether combining accounts would make your finances easier to manage. Your decision should also reflect your tax situation and the type of money in the plan. For example, moving pre-tax savings into a Roth IRA generally creates taxable income, unlike a properly completed pre-tax-to-traditional IRA rollover. Your plan administrator and a qualified tax professional can help clarify the rules that apply to you.

Frequently Asked Questions About Old 401(k) Accounts

Can I leave my 401(k) with a former employer?

Often, yes, if the plan allows it. Rules may differ based on your account balance and the terms of the plan, so check with the plan administrator.

Is rolling over an old 401(k) taxable?

A properly completed rollover of eligible pre-tax 401(k) funds into a traditional IRA or another eligible pre-tax plan generally is not currently taxable. Roth conversions and amounts not rolled over can be treated differently.

What is the difference between a direct and indirect rollover?

A direct rollover moves funds to the receiving account without paying them to you. With an indirect rollover, you receive the distribution and generally must redeposit eligible funds within 60 days; mandatory withholding may apply.

Should I roll my 401(k) into an IRA or my new employer’s plan?

That depends on whether your new plan accepts rollovers and how the alternatives compare on costs, investment choices, distribution rules, and your broader financial needs.
