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

When you leave a job, your 401(k) stays with you — but you have choices about where it goes. You can leave it with your former employer's plan, move it to your new employer's plan, roll it into an Individual Retirement Account (IRA), or cash it out. Each path has different tax consequences, fees, and rules about when you can withdraw money. The wrong choice can cost you thousands in taxes and penalties.

The most common moves are a direct rollover (the plan trustee sends money straight to a new account with no tax hit) and an indirect rollover (you receive a check and have 60 days to deposit it yourself). A direct rollover is almost always simpler and safer because the money never touches your hands, so there is no withholding tax and no risk you will miss the 60-day deadline.

Key Takeaways

  • A direct rollover moves money from your old 401(k) to a new account without taxes or penalties, and the plan administrator handles the transfer.
  • An indirect rollover gives you a check, but your employer withholds 20 percent for taxes, and you must deposit the full amount (including the withheld portion from your own pocket) within 60 days or face a 10 percent early withdrawal penalty plus income tax.
  • Rolling into an IRA gives you more investment choices and lower fees than most 401(k) plans, but you lose access to employer loans and some creditor protections.
  • Cashing out before age 59½ triggers a 10 percent penalty plus income tax on the full amount, and you cannot undo the withdrawal.
  • If you roll money into a new employer's 401(k), confirm the plan accepts rollovers and has lower fees than your old plan before you move.

Direct rollover: the safest path

A direct rollover means the trustee of your old plan sends the money directly to the trustee of your new plan or IRA. You never see the money, no tax is withheld, and there is no 60-day clock. This is the method the IRS prefers and the one that causes the fewest problems.

To start a direct rollover, contact your new plan or IRA provider and ask for their rollover instructions. They will give you the account number and wire details to provide to your old plan. Then contact your old plan administrator (usually your former employer's HR department or the plan's customer service line) and request a direct rollover. Provide the new account details. The old plan will verify the receiving account is set up to accept rollovers, then initiate the transfer. This typically takes one to three weeks.

You will receive a notice from both the old and new plan confirming the transfer. Keep these notices for your tax records. You do not need to report anything special on your tax return for a direct rollover — it is not taxable income.

Indirect rollover: higher risk, but sometimes necessary

An indirect rollover happens when your old plan sends you a check instead of transferring the money directly. Your employer is required to withhold 20 percent of the balance for federal taxes. If your balance is $50,000, you receive a check for $40,000 and the plan sends $10,000 to the IRS.

You then have 60 calendar days from the date you receive the check to deposit the full original amount (the $50,000, not just the $40,000 you received) into an IRA or new 401(k). If you deposit only the $40,000 you received, the missing $10,000 is treated as a withdrawal. You will owe income tax on it, plus a 10 percent early withdrawal penalty if you are under 59½. You cannot undo this — there is no way to fix it after the 60 days pass.

The 20 percent withholding is just an advance on your taxes. When you file your return, if your actual tax liability is lower, you get the difference back as a refund. But you still have to come up with the $10,000 from your own pocket to complete the rollover and avoid the penalty.

Use an indirect rollover only if your old plan will not do a direct rollover. Mark your calendar for day 60 and do not wait until the last week.

Rolling into an IRA versus a new employer plan

An IRA (Individual Retirement Account) and a 401(k) are different containers with different rules. When you roll a 401(k) into an IRA, you gain flexibility but lose some protections.

An IRA typically offers more investment choices — you can hold individual stocks, bonds, mutual funds, and ETFs at most brokers. A 401(k) usually limits you to a menu of 10 to 50 funds chosen by the plan. IRAs also tend to have lower fees. A 401(k) charges administrative fees, investment fees, and sometimes advisor fees. An IRA at a major broker (Vanguard, Fidelity, Schwab) often costs nothing to hold if you are not paying for active management.

But an IRA has drawbacks. You lose access to 401(k) loans — if you need cash, you cannot borrow against an IRA without withdrawing it permanently. An IRA also has less creditor protection than a 401(k) in some states. If you are sued or face bankruptcy, a 401(k) is protected under federal law; an IRA protection varies by state.

Rolling into a new employer's 401(k) makes sense if the plan has low fees, good investment options, and you want to keep everything in one place. But if the new plan is expensive or limited, an IRA is usually the better choice.

Cashing out: the most expensive option

You can ask your old plan to send you the full balance as a check. This is a taxable withdrawal, not a rollover. If you are under 59½, you owe a 10 percent early withdrawal penalty on top of ordinary income tax. If your balance is $50,000 and you are in the 24 percent tax bracket, you owe roughly $17,000 in taxes and penalties, leaving you $33,000.

This is permanent. You cannot put the money back into a retirement account later and recover the tax. The money is gone from your retirement savings forever.

Cashing out makes sense only if you have a genuine financial emergency and no other options. Even then, consider a 401(k) loan (if your plan allows it) or an indirect rollover into an IRA, which at least keeps the money in a tax-deferred account.

What to do before you move your money

Before you initiate any rollover, gather information about both accounts. For your old plan, get the account balance, the current investment allocations, and the plan administrator's contact details. For your new account, confirm it is set up to receive rollovers and get the account number and wire instructions.

If you are rolling into a new employer's 401(k), ask HR for the plan's fee schedule and investment menu. Compare the fees to your old plan and to what an IRA would cost. A difference of 0.5 percent per year compounds significantly over decades.

If you are rolling into an IRA, choose the broker first (Vanguard, Fidelity, and Schwab are common choices with low or no fees), open the account, and then request the rollover from your old plan. Do not cash out the old plan first and then try to open an IRA — that creates an indirect rollover with the 20 percent withholding.

If you have company stock in your 401(k), ask your plan administrator about Net Unrealized Appreciation (NUA). In some cases, rolling company stock into an IRA triggers immediate taxes on the appreciation. A direct rollover of the stock to a taxable brokerage account (not an IRA) may be more tax-efficient. This is complex — consider consulting a tax professional if the stock represents a significant portion of your balance.

Timelines and what to expect

A direct rollover typically takes one to three weeks from the date you request it. The old plan administrator processes the request, verifies the receiving account, and initiates the transfer. You can call the old plan's customer service line to check status after one week.

An indirect rollover is faster on the old plan's end — you receive the check within one to two weeks — but you then have 60 days to deposit it. Do not assume you have time to think about it. Life happens: mail gets delayed, you forget the deadline, or you misplace the check. Treat the 60-day window as a hard deadline.

Once money lands in your new IRA or 401(k), it is invested according to your instructions. If you do not choose investments, some plans default to a money market fund (which earns very little) or a target-date fund (which adjusts risk as you approach retirement). Review your new account within a week of the transfer and confirm your money is invested the way you intended.

Frequently Asked Questions

Can I split my 401(k) between multiple accounts?

Yes. You can roll part of your balance into an IRA and part into a new employer's 401(k), or split it between multiple IRAs. Request separate direct rollovers to each destination. This is useful if you want to keep some money in a 401(k) for creditor protection and move the rest to an IRA for lower fees.

What if I have an old 401(k) from years ago that I forgot about?

Contact your former employer's HR or benefits department and ask for the plan administrator's contact information. They can tell you the current balance and help you initiate a rollover. If the balance is under $5,000, some plans will force you out and send you a check (an indirect rollover). Act quickly if you receive notice of a forced distribution.

Do I have to roll over my entire 401(k), or can I leave some behind?

You can leave money in your old employer's plan indefinitely (as long as your balance is above any minimum, usually $5,000). You can also roll over only part of it. However, if you leave money behind, you will have multiple accounts to track and may pay multiple sets of fees. Most people roll everything out for simplicity.

What happens if I miss the 60-day deadline on an indirect rollover?

Any money not deposited within 60 days is treated as a taxable withdrawal. You owe income tax on it, plus a 10 percent penalty if you are under 59½. The IRS can grant a waiver in rare cases (serious illness, natural disaster, financial institution error), but you must request it in writing. Do not rely on this — meet the deadline.

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

Yes, but it is a conversion, not a rollover. You owe income tax on the full amount converted in the year you do it. This makes sense only if you expect to be in a lower tax bracket that year or believe tax rates will be higher in retirement. Consult a tax professional before converting.
