What happens to your 401(k) when you change jobs or retire

When you leave a job, your 401(k) stays with your former employer's plan unless you move it. You have four main choices: leave it where it is, roll it into your new employer's plan, roll it into an individual retirement account (IRA), or cash it out. Each path has different tax consequences and rules about when you can access the money. Most people who move their 401(k) choose a rollover — either to a new employer plan or to an IRA — because it avoids when ready taxes and penalties.

The specific steps and important date depend on which type of transfer you pick. Some transfers happen directly between institutions (called a direct rollover), which is the safest method. Others require you to receive a check and deposit it yourself within 60 days (called an indirect rollover), which carries more risk of tax problems if you miss the important date.

Key Takeaways

  • A direct rollover, where your old plan sends money straight to your new account, avoids taxes and the 60-day important date that applies to indirect rollovers.
  • Rolling into an IRA gives you more investment choices than most employer plans, but you lose access to certain employer plan protections and may face different withdrawal rules.
  • If you cash out your 401(k) before age 59½, you owe income tax plus a 10 percent early withdrawal penalty on the full amount, unless an exception applies.
  • Leaving your 401(k) with your former employer is allowed if your balance is above a certain amount (usually $5,000), but you lose the ability to borrow from it.

Direct rollover to an IRA: the most common path

A direct rollover into an IRA is the most straightforward transfer. You contact your current 401(k) plan administrator and ask for a direct rollover form. You fill it out with your new IRA account details (the bank or brokerage where you want the money to go), sign it, and send it back. The plan administrator then sends the money directly to your IRA custodian. No check arrives in your hands, and no tax is withheld.

This process typically takes one to three weeks, depending on how quickly your plan processes the request and how fast the receiving institution processes the deposit. You do not owe any taxes on the money in the year of the rollover, and the money continues to grow tax-deferred in your IRA. You can roll over as much as you want — there is no limit on the dollar amount.

Before you start, open an IRA at a bank, brokerage, or investment firm if you do not already have one. Common providers include Fidelity, Vanguard, Charles Schwab, and most major banks. Once the account is open and funded, you can invest the money however you choose within IRA rules.

Rolling into your new employer's 401(k) plan

If your new job offers a 401(k), you can roll your old 401(k) directly into it. Contact your new plan administrator and ask whether they accept rollovers and what form you need to complete. Then contact your old plan administrator with the new plan's details. The money transfers directly between the two plans with no tax consequence.

This option works well if you like your new plan's investment options and want to keep all your retirement savings in one employer account. However, employer plans typically offer fewer investment choices than IRAs, and they have stricter rules about borrowing and withdrawals. Some plans also charge higher fees than IRAs. Ask your new plan administrator for a summary of fees and investment options before you decide.

One advantage of rolling into an employer plan is that you keep access to the plan's loan feature — you can borrow against your balance if you need cash. IRAs do not allow loans. If you roll into an IRA instead, you lose this option permanently.

Indirect rollover: receiving a check and depositing it yourself

An indirect rollover happens when your plan administrator sends you a check instead of sending the money directly to your new account. This is riskier than a direct rollover because you have exactly 60 calendar days to deposit the check into an IRA or another 401(k). If you miss that important date, the IRS treats the money as a distribution, which means you owe income tax on the full amount plus a 10 percent early withdrawal penalty if you are under 59½.

Additionally, your plan administrator must withhold 20 percent of the amount for federal income tax. If you roll over $10,000, you receive a check for $8,000 and owe tax on the $2,000 that was withheld. To avoid owing taxes on that $2,000 when you file, you must deposit the full $10,000 into your new account within 60 days — meaning you need to cover the $2,000 from your own money.

Indirect rollovers happen by accident when you ask for a distribution instead of a rollover, or when your plan does not offer direct rollovers. If you receive a check, mark your calendar for day 60 and deposit it when ready. Do not spend the money or delay the deposit.

Cashing out your 401(k): the tax and penalty cost

If you withdraw your 401(k) as a lump sum instead of rolling it over, you owe federal income tax on the entire amount at your ordinary tax rate. You also owe a 10 percent early withdrawal penalty if you are younger than 59½, unless a specific exception applies. For someone in the 24 percent tax bracket who is under 59½, a $50,000 withdrawal costs $17,000 in taxes and penalties, leaving $33,000.

Some exceptions to the 10 percent penalty exist — for example, if you are disabled, if you are a public safety employee who separated from service at 50 or older, or if you are taking substantially equal periodic payments. These exceptions are narrow and have strict rules. Talk to a tax professional before you cash out if you think an exception might explore.

Cashing out makes sense only in rare situations, such as severe financial hardship or if your balance is very small. In most cases, rolling over preserves far more of your money.

Leaving your 401(k) with your former employer

You can leave your 401(k) with your old employer's plan after you leave the job, as long as your balance is at least $5,000 (some plans set a higher minimum). Your money continues to grow tax-deferred, and you can still access it at retirement age. However, you lose the ability to borrow from the plan, and you cannot make new contributions. You also have less control over the account — if the plan changes administrators or closes, you may be forced to move the money.

This option works if you are satisfied with the plan's investment options and fees, and you do not need to borrow. However, most people find it simpler to consolidate old 401(k)s into one IRA or roll them into their new employer plan so they have fewer accounts to track.

Steps to complete a direct rollover

The process is straightforward if you choose a direct rollover. First, decide where the money will go — either an IRA at a bank or brokerage, or your new employer's 401(k) plan. If you are rolling into an IRA, open the account first and get the account number and routing information from your new custodian.

Next, contact your current 401(k) plan administrator. You can usually find contact information on your plan statement or the employer's benefits website. Ask for a direct rollover form and explain where you want the money to go. Fill out the form with the receiving institution's details, sign it, and return it to your plan administrator. Some plans allow you to request a rollover online through their website.

Once your plan administrator receives the form, they will contact the receiving institution and arrange the transfer. This typically takes one to three weeks. You will receive confirmation from both your old plan and your new custodian when the transfer is complete. Keep these confirmations for your records.

Common mistakes to avoid

The biggest mistake is taking an indirect rollover and missing the 60-day important date. If you receive a check, deposit it when ready — do not wait. Mark your calendar and treat it as urgent.

Another common error is rolling money into an IRA and then later rolling it back into an employer plan without understanding the tax rules. Once money is in an IRA, rolling it back into an employer plan is allowed, but the rules are complex. Talk to a tax professional before you move money a second time.

A third mistake is cashing out a small balance without understanding the tax cost. Even a $5,000 withdrawal can cost $1,700 or more in taxes and penalties if you are under 59½. Rolling over is almost always better.

Finally, some people forget to update their beneficiary designation on the new account. Your old plan's beneficiary does not automatically transfer. Log into your new account and name your beneficiary within a few weeks of the rollover.

Frequently Asked Questions

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

No, you cannot roll over an active 401(k) while you are employed there. You can only roll over a 401(k) after you leave the job. Some plans allow in-service distributions or conversions while you are still employed, but these are different from rollovers and have their own rules. Ask your plan administrator what options are available to you.

What if my old employer went out of business?

If your employer closed or the plan was terminated, your plan administrator is required to distribute your balance to you or roll it over automatically. You should receive a letter explaining your options. If you cannot find your old plan, contact your state's unclaimed property office or the Department of Labor's Employee Benefits Security Administration.

Can I roll over a Roth 401(k) into a regular IRA?

You can roll a Roth 401(k) into a Roth IRA, but not into a regular (pre-tax) IRA. If you roll a Roth 401(k) into a regular IRA, you owe income tax on the earnings portion. Keep Roth money in Roth accounts to avoid this tax bill.

How long does a direct rollover take?

Most direct rollovers complete within one to three weeks. Some plans process faster, and some take longer depending on their procedures and the receiving institution's processing time. Contact your plan administrator for an estimate specific to your situation.

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

You can roll over part of your balance and leave the rest with your old plan, or take part as a distribution. However, if you take any amount as a distribution, that portion is subject to taxes and the 10 percent penalty if you are under 59½. Rolling over the full balance is usually the best choice.
