401(k) Rollover: What to Do With Your Old 401(k) When You Change Jobs

When you leave a job, your 401(k) follows you -- but you have choices. Leave it, roll it to your new 401(k), roll to an IRA, or cash out (don't do this). Here's how to choose the best option.

You have four options for an old 401(k) when you change jobs. Leave it in your former employer's plan (if your balance exceeds $5,000), roll it into your new employer's 401(k), roll it into a Traditional IRA, or cash out. Each has distinct trade-offs around fees, investment control, creditor protection, and loan access. The most common and flexible choice is rolling to a Traditional IRA, which gives you unlimited investment options, lower fees, and full control. Cashing out is almost always a mistake -- you lose 20% to mandatory withholding, pay a 10% early withdrawal penalty, and owe income tax on the full amount. Compare 401(k) vs IRA vs Roth IRA →

Real-world example: Job change, $80K in old 401(k). Options: leave in old plan (fees 0.5%, limited fund choices, no more contributions), roll to new plan (fees 0.3%, good Vanguard funds, loan available), roll to Traditional IRA (fees 0%, VTI/VXUS/BND, full control, easy Roth conversions). Best: roll to IRA. Open Vanguard IRA, roll $80K directly, invest in 60/40 VTI/BND. Lower fees, better options, consolidate accounts. Learn more about retirement planning →

Option 1: Leave It in Your Old Employer's 401(k)

If your balance exceeds $5,000, your former employer cannot force you out of the plan. You can leave the money invested in the plan's fund lineup indefinitely. Benefits include continued access to institutional-class funds (often lower expense ratios than retail share classes), creditor protection under ERISA (federal law protects 401(k) assets from bankruptcy and most lawsuits), and the ability to take loans if the plan allows them for separated participants. Drawbacks: you cannot make additional contributions, investment choices are limited to the plan's menu, the plan may charge administrative fees to former employees, and you now have another account to track.

Option 2: Roll to Your New Employer's 401(k)

Moving assets to your new company's 401(k) plan consolidates your retirement savings into one account. Benefits include simplified management, continued ERISA creditor protection, and eligibility for 401(k) loans (if your new plan allows them). Drawbacks: your new plan may have higher fees or worse fund options than your old plan or an IRA. Before rolling, compare the new plan's expense ratios, fund lineup, and administrative fees against what you currently have. Some new plans have excellent low-cost institutional funds; others charge high fees with limited options. If the new plan is inferior, roll to an IRA instead.

Option 3: Roll to a Traditional IRA

Rolling your 401(k) to a Traditional IRA is the most popular choice. Benefits include unlimited investment choices (individual stocks, ETFs, mutual funds, bonds, options, real estate through self-directed IRAs), lower fees (no plan administrative fees), full control over asset allocation, and easier Roth IRA conversions. Drawbacks: no 401(k)-style loan option, and less creditor protection (some states protect IRAs, but federal bankruptcy protection for IRAs is limited to approximately $1.5 million). To execute a direct rollover, have your 401(k) provider transfer funds directly to your IRA custodian. The transfer is tax-free and penalty-free. Explore Roth conversion strategies →

Option 4: Cash Out (Do Not Do This)

Cashing out your 401(k) when you leave a job triggers three tax events. First, the plan must withhold 20% for federal income tax (you may owe more at tax time). Second, you pay a 10% early withdrawal penalty if you are under 59.5. Third, the entire distribution counts as ordinary income for the year. On a $50,000 401(k), you lose $10,000 to mandatory withholding, $5,000 to the early withdrawal penalty, and approximately $8,000 to income tax (assuming 22% bracket). Your net proceeds: roughly $27,000 from a $50,000 balance. The only exception is if you have a qualified financial hardship or if the balance is less than $1,000 (the employer can force you out, but you should still roll it over rather than cash out).

Should I roll my 401(k) to an IRA?

For most people, yes. An IRA offers lower fees, unlimited investment choices, and full control over your retirement savings. The main situations where you might keep the 401(k) are if you need the stronger creditor protection that ERISA provides (relevant for high-liability professions like doctors or lawyers), if you want access to 401(k) loans, or if your current plan has exceptionally low-cost institutional funds that you cannot access in an IRA. For everyone else, rolling to a Traditional IRA is the best move. If you plan to do Roth conversions, an IRA is also significantly easier to manage because you can convert any dollar amount at any time. Compare 401(k) vs IRA vs Roth IRA →

What happens to my 401(k) when I quit my job?

When you quit your job, your 401(k) stays in the plan until you decide what to do with it. If your balance is over $5,000, the plan cannot force a distribution. You can leave it indefinitely. If your balance is between $1,000 and $5,000, the plan can force a distribution to a rollover IRA in your name. If your balance is under $1,000, the plan can cash you out (they will send you a check minus withholding). You have 60 days from the distribution date to roll the funds into another qualified account to avoid taxes and penalties. Always initiate a direct rollover to avoid the 60-day time limit and mandatory withholding.

Can I roll my 401(k) to a Roth IRA?

Yes, you can roll a 401(k) to a Roth IRA, but you will owe income tax on the pre-tax amount converted. If your 401(k) is entirely pre-tax contributions, the full rollover amount is taxable as ordinary income in the year you do the conversion. This can be a significant tax bill if you have a large balance. Consider spreading the conversion over multiple years to manage tax brackets. If you have a Roth 401(k), those funds can roll directly to a Roth IRA tax-free. If you have after-tax (non-Roth) contributions in your 401(k), those can roll to a Roth IRA tax-free as well, while the earnings on those after-tax contributions are taxable.

What is the 60-day rollover rule?

The 60-day rollover rule allows you to take a distribution from your 401(k) and roll it into another qualified retirement account within 60 days without triggering taxes or penalties. If you miss the 60-day deadline, the distribution is treated as a taxable withdrawal and you may owe the 10% early withdrawal penalty. The key risk: if you take an indirect rollover (check made out to you), the plan must withhold 20% for taxes. You need to come up with that 20% from your own pocket to roll over the full amount within 60 days. You get the 20% back as a tax refund when you file your return. Always choose a direct rollover (custodian-to-custodian transfer) to avoid these complications entirely.
