Your 401(k) stays in your name when you leave a job. The money you contributed is always yours, and you typically have several options for what to do with it: leave it where it is, roll it into a new account, or cash it out. What happens to your employer’s contributions depends on how long you worked there, and any outstanding loans come with strict repayment deadlines. Here’s how each piece works.
Your Contributions Stay Yours
Every dollar you contributed from your own paycheck, including any investment gains on those contributions, belongs to you no matter when you leave. The IRS rule is straightforward: employee elective deferrals are always 100% vested. Your employer cannot take back any portion of what you put in.
The same applies to Roth 401(k) contributions if your plan offered that option. Whether you worked at the company for six months or six years, your side of the account is fully yours on your last day.
Employer Matches May Not Be Fully Yours
The employer match is where things get more complicated. Companies use vesting schedules to determine how much of their contributions you actually own based on your years of service. If you’re not fully vested when you leave, you forfeit the unvested portion.
There are two common vesting structures. With cliff vesting, you own 0% of the employer match until you hit three years of service, at which point you jump to 100%. With graded vesting, your ownership increases gradually: 20% after two years, 40% after three, 60% after four, 80% after five, and 100% after six years. Some employers offer immediate vesting, meaning you own the match from day one.
Your plan’s specific schedule is spelled out in the plan document, which you can request from HR or your plan administrator. A “year of service” generally means working at least 1,000 hours over a 12-month period. If you leave before you’re fully vested, the unvested employer contributions are forfeited back to the plan. You keep the rest.
Four Options for Your Account
Once you’ve separated from your employer, you have four paths for the money.
- Leave it in the old plan. Many plans let former employees keep their money invested. This can make sense if the plan has low fees or investment options you like. You won’t be able to make new contributions, but the money continues to grow tax-deferred.
- Roll it into your new employer’s 401(k). If your next job offers a 401(k) that accepts rollovers, you can transfer the balance there. This keeps everything in one place and maintains the same tax-deferred status.
- Roll it into an IRA. Moving the money to a traditional IRA gives you more control over investment choices. The tax treatment stays the same as a traditional 401(k), and there’s no tax hit if the rollover is done correctly.
- Cash it out. You can withdraw the balance, but this is the most expensive option. More on that below.
If your balance is small (typically $5,000 or less), your former employer may require you to move the money out. Some plans automatically roll small balances into an IRA on your behalf if you don’t respond within a set timeframe.
How Rollovers Work
The safest way to move your 401(k) is a direct rollover, where the plan administrator sends the money straight to your new retirement account. No taxes are withheld, and you don’t have to worry about deadlines. You contact your old plan administrator and your new account provider to coordinate the transfer. The check may be made payable to your new account rather than to you personally.
The riskier route is an indirect rollover, where the plan sends the money to you first. This triggers mandatory 20% federal tax withholding on the distribution. If you want to complete the rollover and avoid taxes, you have 60 days to deposit the full original amount into a qualifying retirement account. That means you’d need to come up with the 20% that was withheld from other funds and deposit it along with the check you received. When you file your tax return, the withheld amount gets credited back to you. If you miss the 60-day window or deposit less than the full amount, the shortfall is treated as a taxable distribution.
A direct rollover avoids this entire headache. There’s rarely a good reason to choose the indirect route.
The Cost of Cashing Out
If you take the money as a cash distribution instead of rolling it over, you’ll owe federal and state income taxes on the entire amount. The distribution gets added to your taxable income for the year, which could push you into a higher tax bracket.
On top of that, if you’re under age 59½, you’ll pay an additional 10% early withdrawal penalty. So on a $50,000 cashout, someone in the 22% federal tax bracket could lose roughly $16,000 between income taxes and the penalty, before state taxes. The actual damage depends on your total income and tax situation, but the combination of regular income tax plus the 10% penalty makes cashing out one of the most expensive financial moves you can make.
There are limited exceptions to the 10% penalty. Leaving your job during or after the year you turn 55 is one (this applies to 401(k) plans specifically, not IRAs). Other exceptions include disability, certain medical expenses, and IRS levy situations.
Outstanding 401(k) Loans
If you borrowed from your 401(k) and still have an unpaid balance when you leave, you typically have 60 to 90 days to repay it in full. The exact deadline depends on your plan’s rules. Once you separate from the employer, you can no longer take new loans from that plan, even if you leave your balance there.
If you can’t repay the loan within the deadline, the remaining balance is treated as a taxable distribution. That means you’ll owe income taxes on it, plus the 10% early withdrawal penalty if you’re under 59½. A $10,000 unpaid loan balance could cost you $3,200 or more in taxes and penalties. Before you leave a job, check your loan balance and plan terms so you’re not caught off guard.
How Long You Have to Decide
There’s no hard federal deadline forcing you to move your 401(k) the moment you quit. If your balance is above the plan’s minimum threshold for keeping former-employee accounts, the money can sit in your old plan indefinitely. That said, it’s worth making a decision within a few months. Old accounts are easy to forget, and you lose the ability to adjust contributions or take loans. Former employers can also change plan providers, which occasionally creates administrative confusion for account holders who aren’t paying attention.
If you’re rolling to an IRA or a new 401(k), starting the process within a few weeks of your last day keeps things simple. Contact your former plan administrator to understand the specific steps, required forms, and any processing timelines. Most direct rollovers complete within one to three weeks once the paperwork is submitted.
