Quick Answer
IRAs and 401(k)s are both tax-advantaged retirement accounts, but an IRA is for individual savers and 401(k)s are employer-based plans for employees. Different contribution limits and rules apply.
Two common ways to save for retirement are through individual retirement accounts (IRAs) and 401(k) plans. A 401(k) is an employer-based retirement account. An IRA is opened and funded individually. Both types of retirement accounts offer tax advantages; each has unique features and benefits worth considering.
Myth buster: Are you worried that you need to choose between a 401(k) and an IRA? Fortunately, that's not the case. Many people use both. Multiple accounts can diversify your holdings and maximize the amount you can contribute.
Here's more about when and how to contribute to a 401(k) and/or IRA, and how these two types of accounts stack up.

What Is a 401(k)?
Tax-advantaged 401(k) plans allow employees to save for retirement at work. Under a traditional 401(k) plan, you can arrange to have a portion of your paychecks automatically directed to retirement savings. These elective deferrals are excluded from your gross pay, which reduces your taxable income. You won't pay income taxes on earnings while your money grows in your account. However, you will pay income taxes on the money you withdraw when you retire.
You may also have the option of funding a designated Roth 401(k), which offers different tax benefits. Although you don't get a tax deduction for contributions with a Roth 401(k), your investments grow tax-free inside your account and qualified withdrawals from your Roth are tax-free.
What Is an IRA?
An IRA is an individual retirement account you can open, fund and invest yourself. Unlike 401(k)s, IRAs aren't linked to your employment. Anyone who has taxable compensation can contribute to their own IRA. Both traditional and Roth IRAs are widely available from banks, credit unions, brokerages and mutual fund companies.
Types of IRAs
Although all IRAs are geared toward tax-advantaged retirement savings, there are different types of IRAs.
- Traditional IRAs allow you to exclude your contributions from your taxable income. You won't pay taxes on your money as it grows, but you will pay taxes on it when you withdraw it in retirement.
- Roth IRAs are funded with after-tax dollars (no tax deduction), but money grows tax-free while it's in your account, and isn't taxed when you withdraw it in retirement.
- Spousal IRAs allow nonworking spouses to contribute to their retirement even if they don't have qualifying taxable income.
- Rollover IRAs are for funds rolled over from past 401(k)s and IRAs.
Some IRAs are intended for small businesses and business owners.
- Simplified employee pension (SEP) IRAs allow business owners to contribute to both their employees' and their own retirement savings. Only employers may contribute.
- Savings Incentive Match Plan for Employees (SIMPLE) IRAs allow elective contributions from employees, similar to a 401(k).
Tip: Sole proprietors can also choose solo 401(k)s, which are essentially 401(k) plans for business owners and self-employed people with no employees. Contribution limits are the same as for regular 401(k)s, but you may be able to contribute as both an employer and employee, raising your total contribution limit.
What Is the Difference Between an IRA and a 401(k)?
The primary difference between an IRA and a 401(k) is eligibility. IRAs are for individual investors and 401(k)s are for employees. Though these two types of accounts may have more similarities than differences, here are some of their key differentiators, along with a few common areas worth understanding.
Eligibility
IRA: IRAs are individual retirement accounts anyone can open, as long as they have taxable income.
401(k): A 401(k) is an employer-based retirement plan that may be offered as an employee benefit.
Contribution Limits
IRA: You can contribute up to $7,500 to an IRA in 2026. If you're age 50 or older, you can contribute an additional $1,100 for a total contribution of $8,600.
401(k): For the 2026 tax year, you can contribute up to $24,500 to a 401(k) plan. If you're age 50 or older, you can contribute an additional $8,000 for a total contribution of $32,500, or up to an additional $11,250 if you're ages 60 to 63. These contribution limits do not include employer matching dollars. Your total contributions, including employer matching, can't exceed 100% of your compensation, up to $72,000, for 2026.

Employer Matching
IRA: Since most IRAs are not employer-based, there is no employer matching. The exception is a SIMPLE IRA, designed for small business owners and their employees. A SIMPLE IRA allows employer matching, but IRAs geared toward individual savers do not.
401(k): Employers are allowed (but not required) to match employee contributions to a 401(k). Your employer may match your contribution 100% or partially.
Example: A common match is 5%. If you make $100,000 and contribute 10% of your pay to your 401(k) ($10,000), your employer will match 5% of your pay, or $5,000. Your total annual 401(k) contribution, with employer match, is $15,000.
Vesting
IRA: Because IRAs are funded with your money, the funds in an IRA are always yours: No vesting period required.
401(k): Some employers require a vesting (or waiting) period before employer contributions to a 401(k) vest, or become yours. If you leave your job before your employer contributions vest, you'll lose out on that money. Contributions you've made yourself always belong to you.
Loans
IRA: Loans against IRAs are not allowed.
401(k): Instead of withdrawing money, you may be able to borrow against your 401(k). Not all retirement plans allow loans, and individual plans will have their own parameters. In general, you may be able to borrow $50,000 or 50% of your account balance (whichever is less), and pay yourself back over five years.

Investments and Fees
IRA: IRAs are generally invested in stocks, bonds, CDs, index funds, exchange-traded funds (ETFs) or mutual funds. As an IRA owner, you choose the mix of investments. Fees vary, so you may want to check expense ratios, advisory fees and transaction fees before opening an IRA to get a clear understanding of potential costs.
401(k): Your 401(k) plan may invest in similar holdings, but your choices are generally limited to what the provider offers. A 401(k) may have higher expense ratios and administrative fees than a typical IRA, but check your individual plan. In some cases, employers cover part of these costs.
Roth Options
Roth options are available for both IRAs and 401(k)s. Roth IRAs and Roth 401(k)s are funded with after-tax dollars; you don't get a tax deduction for contributions. However, early withdrawal rules are more forgiving for Roth accounts.
You can withdraw your contributions (not earnings) tax- and penalty-free at any time, and can take qualified (tax-free) distributions after age 59½, as long as your account has been open for at least five years.

Early Withdrawals
Early withdrawal rules for IRAs and 401(k)s are similar: With a few exceptions, funds you withdraw from a traditional IRA or 401(k) before age 59½ are subject to a 10% penalty and regular income tax. The same early withdrawal penalty applies when you withdraw earnings from a Roth IRA or Roth 401(k), but with a Roth account you can withdraw your contributions at any time penalty-free.

Required Minimum Distributions
You're required to take minimum distributions from your traditional IRA or 401(k) when you reach age 73. Required minimum distributions (RMDs) don't apply to Roth IRAs and Roth 401(k)s, as long as the account owner is alive. However, RMDs do apply to most types of IRAs and 401(k)s, and to beneficiaries who inherit Roth accounts.
How to Choose Between an IRA and a 401(k)
Both 401(k) plans and IRAs are essential tools when you're saving for retirement. Both are widely available and offer tax advantages that can help you maximize your savings over time.
Where should you invest your hard-earned dollars if you have to choose between a 401(k) and an IRA? Here are a few perspectives to consider.
When to Choose an IRA
An IRA is a great alternative when a 401(k) plan isn't available to you, for instance because you're self-employed or a nonworking spouse. IRAs are easy to open: You can establish an IRA or Roth IRA at most banks, credit unions, mutual fund companies or investment brokerages. An IRA is also a simple option if you have a lump sum to contribute.
When to Choose a 401(k)
If your employer offers a 401(k) plan, it's probably worth considering. Elective deferrals taken out of your paycheck make it easy to invest regularly. Matching funds provide an immediate return on your investment, though you may have to wait to become fully vested before all of your funds are yours. Higher contribution limits mean it's possible to sock away money at a healthy clip.
Can You Have Both a 401(k) and an IRA?
If you have enough money to invest, you may want to contribute to both a 401(k) and an IRA. The IRS has income limits that may affect your ability to make a Roth IRA contribution or deduct a traditional IRA contribution when you or your spouse also contribute to a workplace retirement plan. But as long as you're eligible, you might consider contributing to both types of accounts if you've maxed out your 401(k) contributions (or employer match), or if you're interested in options that aren't available through your employer's 401(k)—for example, a Roth account.
Maintaining both a 401(k) and an IRA requires a bit more brain power: You'll have multiple accounts to track. But, if you have the funds, contributing to both an IRA and a 401(k) lets you maximize your tax-advantaged savings.
Frequently Asked Questions
The Bottom Line
Saving for retirement is a marathon, not a sprint. Using tax-advantaged accounts like 401(k)s and IRAs can help you maintain your pace as you build your nest egg over time. Participating in your employer's 401(k) plan can help you save consistently and take advantage of matching funds. Opening and funding a traditional or Roth IRA gives you an additional opportunity to save—and save money on taxes. Either type of account can help you meet your retirement goals. Over the long haul, if you're serious about saving for retirement, you may want both.
