What happens when you close a 401(k)
Closing a 401(k) means you stop contributing to it and take the money out. The account itself ends, but what happens to your balance depends on your age, whether you still work there, and which option you choose. You cannot straightforward withdraw the money and keep it in a regular bank account without consequences — the IRS has rules about how and when you can take 401(k) money out, and breaking those rules costs you in taxes and penalties.
The most common reason people close a 401(k) is leaving a job. When you leave, your employer's plan no longer accepts contributions from you, but your money stays in the account until you move it or withdraw it. You have several paths forward, and choosing the right one saves you thousands in taxes.
Key Takeaways
- You cannot close a 401(k) while still employed at the company that sponsors it, unless your plan allows in-service withdrawals.
- After you leave a job, you can roll your 401(k) into an IRA, roll it into a new employer's plan, take a lump-sum withdrawal, or leave it where it is.
- A rollover to an IRA or new employer plan avoids when ready taxes and penalties; a lump-sum withdrawal triggers income tax and a 10% penalty if you are under 59½.
- If you do not move the money within 60 days of withdrawal, the IRS treats it as taxable income and may assess penalties.
- The plan administrator must give you a written explanation of your options before you withdraw.
Whether you can close a 401(k) while still employed
If you still work for the company that sponsors your 401(k), you cannot close the account and take the money out in most cases. The plan rules do not allow it. You can stop contributing, but the balance stays locked in the account.
Some plans offer in-service withdrawals, which let you take money out while still employed. These are rare and usually limited to people age 59½ or older, or to hardship situations like medical bills or foreclosure. Your plan document or HR department can tell you whether yours allows them. If it does, you still owe income tax on the withdrawal, and you may owe the 10% early-withdrawal penalty if you are under 59½.
The only way to truly close a 401(k) while employed is to leave the job. Once you separate from the company, you control what happens next.
Rolling over to an IRA or new employer plan
A rollover moves your 401(k) balance directly to another retirement account without triggering taxes or penalties. This is the most common choice and usually the smartest one, because it keeps the money growing tax-deferred and avoids the 10% early-withdrawal penalty.
You have two main rollover targets. A traditional IRA rollover moves the money into an IRA you open at a bank, brokerage, or credit union. You control the investments, and you can keep the money there indefinitely. A direct rollover to a new employer's 401(k) moves the money into your new job's plan if it accepts rollovers. Not all plans do, so check with your new employer's benefits office first.
The key word is direct. The plan administrator sends the money straight to the new account — you never touch it. If the check comes to you instead, you have 60 days to deposit it into the new account yourself, or the IRS treats it as a withdrawal and taxes you on the full amount. Even one day late disqualifies you from the rollover protection.
Taking a lump-sum withdrawal
A lump-sum withdrawal means you take all the money out as a single payment. The plan sends you a check or deposits it into your bank account. This closes the account, but it comes with a steep tax bill.
The entire withdrawal counts as taxable income for that year. If you are under 59½, you also owe a 10% early-withdrawal penalty on top of the income tax. For example, if you withdraw $50,000 and you are in the 22% tax bracket, you owe $11,000 in federal income tax plus $5,000 in penalty — $16,000 total. Your state may tax it too.
The plan administrator withholds 20% of the withdrawal for federal taxes automatically, but that is usually not enough to cover your actual tax bill. You may owe more when you file your return. Take a lump-sum withdrawal only if you have a genuine need for the money now and understand the cost.
Leaving the money in your old plan
You do not have to do anything when ready after you leave a job. Your 401(k) balance can stay in your former employer's plan indefinitely, as long as the balance is above the plan's minimum (often $5,000). The money continues to grow tax-deferred, and you still cannot withdraw it penalty-free until age 59½ unless you may have access to for an exception.
This option makes sense if you like the plan's investment choices, the fees are low, or you are not ready to decide. The downside is that you lose the ability to contribute, and you may have less control over the account once you leave. Some employers eventually force out small balances by doing an involuntary distribution, which means they close the account and send you the money — triggering the tax and penalty rules above.
If you leave the money in the old plan, you still have to take required minimum distributions starting at age 73 (as of 2023). The IRS requires you to withdraw a certain amount each year, calculated by your age and account balance. Miss a withdrawal and you owe a 25% penalty on the amount you should have taken out.
The 60-day rollover window and what can go wrong
If you request a check from your 401(k) instead of a direct rollover, you have exactly 60 calendar days to deposit it into another retirement account. The clock starts the day you receive the check, not the day you request it. Weekends and holidays count.
Missing the important date means the IRS treats the entire amount as a taxable withdrawal. You owe income tax on it, plus the 10% penalty if you are under 59½. You cannot undo this by depositing the money later — the tax bill stands. Some plans and IRAs allow a one-time exception if you missed the important date due to circumstances beyond your control, but you have to request it in writing and the decision is up to the institution.
To avoid this trap, request a direct rollover whenever possible. If you must take a check, deposit it when ready and keep proof of the deposit date.
Taxes, penalties, and what the plan must tell you
Before you withdraw or roll over your 401(k), the plan administrator must send you a written notice explaining your options, the tax consequences, and the 60-day rollover important date. This is called a 402(f) notice. Read it carefully — it tells you exactly what will happen to your money and what you owe.
If you take a lump-sum withdrawal, the plan withholds 20% for federal income tax automatically. This is not your final tax bill — it is just a down payment. When you file your tax return, you may owe more or get a refund depending on your total income and tax bracket for the year.
The 10% early-withdrawal penalty applies only if you are under 59½ and do not may have access to for an exception. Exceptions include disability, medical expenses over 7.5% of your income, health insurance premiums while unemployed, and a few others. If you think you may have access to, talk to a tax professional before you withdraw — the penalty is steep and you want to be sure.
Frequently Asked Questions
Can I close my 401(k) and take the money if I am still working there?
No, not in most cases. Once you leave the job, you can move or withdraw the money. If your plan offers in-service withdrawals and you are 59½ or older, you may be able to withdraw while still employed, but you will owe income tax on it. Check with your HR department about your specific plan.
What is the difference between a rollover and a withdrawal?
A rollover moves your money to another retirement account with no when ready tax bill. A withdrawal takes the money out and counts as taxable income. If you are under 59½, a withdrawal also triggers a 10% penalty unless you may have access to for an exception.
Do I have to pay taxes if I roll over my 401(k) to an IRA?
No, not when ready. A direct rollover is tax-free because the money goes straight from the 401(k) to the IRA. You will owe taxes later when you withdraw the money in retirement. If you take a check and deposit it yourself, you have 60 days or the IRS treats it as a taxable withdrawal.
What happens if I miss the 60-day rollover important date?
The entire amount becomes taxable income for that year, and you owe a 10% penalty if you are under 59½. You cannot undo this by depositing the money later. Some institutions allow a one-time exception for circumstances beyond your control, but you must request it in writing.
Can I leave my 401(k) with my old employer after I quit?
Yes, as long as your balance is above the plan minimum, usually $5,000. The money stays there and grows tax-deferred, but you cannot contribute anymore. You must take required minimum distributions starting at age 73, or you face a 25% penalty on the amount you should have withdrawn.
