No, a 401(k) is not an IRA account

A 401(k) and an IRA are separate retirement accounts with different rules, different limits, and different ways they work. A 401(k) is a workplace retirement plan that your employer sets up and often contributes to. An IRA is an individual retirement account that you open and fund yourself. You can have both at the same time, but they are not the same thing, and the money in one does not count toward the limits in the other.

The confusion happens because both accounts let you save for retirement with tax advantages. But the source of the money, who controls the account, how much you can put in each year, and what happens when you leave a job are all different. Understanding which account you have matters because the rules that apply to one do not apply to the other.

Key Takeaways

  • A 401(k) is a workplace plan your employer offers; an IRA is an individual account you open on your own.
  • Your employer may match contributions to your 401(k), but IRAs have no employer match.
  • 401(k) contribution limits are higher than IRA limits, and the two limits are separate—maxing out one does not affect how much you can put in the other.
  • When you leave a job, your 401(k) stays with that employer's plan until you move it; an IRA moves with you automatically.
  • Withdrawals before age 59½ usually trigger penalties in both accounts, but the rules about when you must start withdrawing are different.

How a 401(k) comes from your employer

Your employer creates and administers a 401(k) plan. You enroll through your workplace, and money is deducted from your paycheck before taxes are calculated. Your employer chooses the investment options available in the plan—you cannot invest in anything outside that menu. Many employers also contribute money to your account as a match: if you put in 3 percent of your salary, they might put in 3 percent as well.

The employer is responsible for making sure the plan follows federal rules and for sending your contributions to the plan administrator. If your employer stops offering the plan or you leave the job, the money stays in the account, but you lose access to any future employer match. You can then move the money to an IRA or to a new employer's 401(k) plan through a process called a rollover.

How an IRA is opened and funded by you

An IRA is opened at a bank, brokerage, or investment company—you choose where. You fund it yourself with money from your paycheck, a bonus, self-employment income, or any other source. No employer is involved. You decide how much to contribute each year (up to the annual limit), and you choose the investments from whatever options that institution offers.

An IRA is yours to keep no matter where you work or whether you change jobs. There is no employer match because there is no employer involved. If you are self-employed or have no workplace retirement plan, an IRA may be your only option for tax-advantaged retirement saving. You can also open an IRA even if you have a 401(k) at work—the two accounts exist separately.

Contribution limits are separate for each account

The annual limit for 401(k) contributions is higher than the limit for IRAs. In 2024, you can contribute up to $23,500 to a 401(k) and up to $7,000 to an IRA. These limits are independent: putting $7,000 into an IRA does not reduce how much you can put into a 401(k). If you have both accounts, you can contribute the full amount to each one in the same year.

The limits change each year based on inflation. If you are age 50 or older, both accounts allow catch-up contributions—an additional $7,500 for a 401(k) and an additional $1,000 for an IRA. Check the current year's limits with your plan administrator or the IRS website, because the numbers shift annually.

Tax treatment differs between the two account types

Most 401(k) plans are traditional, meaning contributions reduce your taxable income in the year you make them, and you pay income tax on withdrawals in retirement. Some employers also offer a Roth 401(k) option, where contributions are made with after-tax money, but withdrawals in retirement are tax-free.

IRAs come in two main types: traditional and Roth. Traditional IRA contributions may be tax-deductible depending on your income and whether you have a workplace retirement plan. Roth IRA contributions are never deductible, but withdrawals in retirement are tax-free. The type of account you choose affects your taxes now and in retirement, so the choice depends on your current tax bracket and what you expect in retirement.

What happens to your money when you leave a job

When you leave an employer, your 401(k) stays with the plan administrator unless you move it. You have several options: leave it where it is (if the balance is large enough), roll it into your new employer's 401(k) plan, or roll it into an IRA. A rollover moves the money without triggering taxes or penalties, but you must complete it within 60 days or the IRS treats it as a withdrawal and taxes apply.

An IRA is not tied to any employer, so it goes with you automatically when you change jobs. You do not have to do anything—the account remains open and invested. This makes an IRA simpler if you change jobs frequently or are self-employed, because you have one account that accumulates over time rather than multiple 401(k)s scattered across past employers.

Required withdrawals start at different ages

With a traditional 401(k), you must start taking withdrawals by April 1 of the year after you turn 73 (this age changed from 72 in 2023 under the SECURE 2.0 Act). The amount is calculated based on your age and account balance. If you do not take the required amount, the IRS charges a penalty on the shortfall.

Traditional IRAs have the same required withdrawal age of 73, but the calculation method can differ slightly. Roth IRAs have no required withdrawals during your lifetime—you can leave the money invested as long as you want. Roth 401(k)s do require withdrawals at 73, even though contributions were made with after-tax money. If you want to avoid forced withdrawals, a Roth IRA is the only option.

Frequently Asked Questions

Can I have both a 401(k) and an IRA at the same time?

Yes. You can contribute to both accounts in the same year, and the contribution limits are separate. The only limit is your total income—you cannot contribute more than you earned. Having both lets you save more for retirement and use different tax strategies in each account.

What happens to my 401(k) if I do not roll it over when I leave my job?

The money stays in the plan with the previous employer's administrator. You can leave it there indefinitely if the balance is above the minimum (usually $5,000), but you lose access to any employer match and may have limited investment choices. Rolling it to an IRA or a new employer's plan usually gives you more control and lower fees.

Can I move money from a 401(k) to an IRA?

Yes, through a rollover. Contact your 401(k) plan administrator and request a direct rollover to an IRA. The money moves directly from the plan to the IRA without passing through your hands, so no taxes or penalties apply. You have 60 days if the check is sent to you instead, or the withdrawal is taxed as income.

Which account should I use if I am self-employed?

You cannot have a 401(k) unless you set up a solo 401(k) specifically for self-employed people. Most self-employed people use an IRA, a SEP-IRA, or a Solo 401(k). A SEP-IRA allows higher contributions than a regular IRA and is simpler to administer if you have no employees. Talk to a tax professional about which fits your situation.

Do I pay taxes on 401(k) and IRA contributions?

It depends on the account type. Traditional 401(k) and traditional IRA contributions reduce your taxable income in the year you make them—you pay taxes later on withdrawals. Roth contributions are made with after-tax money, so you do not get a tax deduction now, but withdrawals in retirement are tax-free. Choose based on whether you want to reduce taxes now or in retirement.
