IRAs and 401(k) plans both help individuals save for retirement, but have their differences

Explore the key differences between 401(k) plans and IRAs

A 401(k) is employer-sponsored, may include matching contributions, and allows higher annual contributions (up to $23,000). An IRA is self-managed, offers greater control over investments, and has lower contribution limits ($7,000). Both plans come in traditional and Roth options, but income caps may limit IRA choices, while 401(k)s have no such restrictions.

A basic guide to retirement savings account options, the IRA and the 401(k)

The two main types of accounts are 401(k) plans and individual retirement accounts (IRAs)—but what do those mean, exactly? There are differences between the two types, as well as the subtypes beneath them.

The IRS sets new contribution limits for IRAs and 401(k) plans each year

In 2024, individuals could contribute up to $7K across all their IRAs. People aged 50 and older could contribute up to $8K. For 2025, the IRS kept the same contribution limits.

401(k) plans and pensions differ in who has control over the investments

With pension plans, a company contributes to an investment fund from which it distributes regular payments to a retired worker until their death. A 401(k) gives the worker control over contributions in a tax-advantaged account.

Having two retirement accounts has its pros and cons

Contributing to both an IRA and a 401(k) lets you increase your retirement savings by about 30% every year. However, you’ll also spend more time actively investing that money and pay more in fees.

Some people roll their 401(k) into an IRA to have more control over their account

However, some argue that you could end up paying less money to invest in a 401(k) plan than you would to invest in an IRA. This article offers a list of pros and cons regarding rolling a 401(k) into an IRA.

Although anyone can contribute to a traditional IRA, not everyone can access its tax deductions

If you or your spouse contributes to a 401(k), you likely won’t be able to deduct your traditional IRA contributions from your taxes. On the flip side, if you don’t contribute to an employer-sponsored retirement account, you’re probably eligible for that tax deduction.

There are four main types of IRAs to choose from

Those types are traditional, Roth, SEP, and SIMPLE. While all IRAs can help you save for retirement, each type has its own tax advantages and eligibility requirements, such as employment type or income level.

The prevalence of 401(k) plans and IRAs over pensions shifted investment risk from employers to employees

The shift also reduced administrative costs for companies—and left millions without guaranteed retirement income. 401(k) plans were introduced in Section 401(k) of the 1978 Revenue Act, which was originally intended as a loophole for people like executives rather than the average employee.

Roth 401(k) plans vs regular 401(k) plans

A normal 401(k) defers tax payments to later, while a Roth requires no tax payments at withdrawal time. Financial experts often recommend investing in a Roth 401(k) plan or Roth IRA when someone first starts their career to lock in a relatively low tax rate.

A 401(k) plan allows workers to save for retirement without paying taxes until later

With a 401(k) plans you can invest more money now and let it grow with compound interest. Americans have more than $7T invested in these types of accounts.

An individual retirement account is a type of tax-advantaged investment account

An IRA lets individuals at most income levels invest either pre- or post-tax money for retirement. IRAs are often good solutions for people who don’t have the option to invest in a 401(k) plan—or for those who want to put even more money aside for retirement.

529s vs. Roth IRA

Roth IRAs and 529 plans both offer tax advantages, but they serve different goals. 529s are state-run accounts meant for education, offering tax-free growth and withdrawals for qualified expenses. Roth IRAs are built for retirement, but can also be tapped for education, with more investment flexibility and fewer contribution limits.

Learn about the differences between traditional and Roth IRAs

Traditional IRAs allow tax-deductible contributions, but withdrawals in retirement are taxed as income. Roth IRAs use after-tax dollars, offering tax-free withdrawals later, but income limits may restrict eligibility. Choosing between the two depends on your financial situation today and your future tax outlook.

Technically speaking, a 401(k) is a type of pension

The Employee Retirement Income Security Act of 1974 lumped both defined-contribution plans like 401(k) plans, and defined benefit plans (like what is colloquially known as a pension) under the term “pension” in order to protect workers and make retirement plan enforcement simpler.

Spousal IRAs give spouses who do not work a way to save for retirement

In most cases, only working individuals can open and contribute to an IRA. But the IRS has a special exception for married couples: the spousal IRA. It lets the working spouse open and contribute to an IRA on behalf of their nonworking spouse.

If your job doesn’t offer a 401(k), you still have retirement savings options

Do you know more than a third of working adults aren't offered a 401(k) through their jobs? If you're part of that group, you still have options for retirement savings, including IRAs, taxable investment accounts, and more.

Roughly 70 million Americans have 401(k) plans

Ted Benna, a rural benefits consultant, proposed a reinterpretation of a small tweak to the Internal Revenue Code in 1980. This led to a fundamental transformation of how American workers plan for retirement.

The 401(k) is limited in its ability to provide guaranteed retirement income

Part of the problem is the high, often hidden fees associated with the accounts and a lack of access. Plus, analysts say the annual cost in tax revenue to the government is more than $100B.

401(k) plans had an average of $112K as of 2023

The median, however, is much lower at around $27K. The average balance of a 401(k) in the US differs across different age groups and income levels.

You have to earn under a certain gross amount per year to be eligible for a Roth IRA

A Roth IRA might make the most sense for someone confident that they will have a higher income in retirement than they do now. For 2025, those allowed to contribute to a Roth IRA must have a modified adjusted gross income (MAGI) of less than $150K.

About 98% of companies offering employees a 401(k) plan match employee contributions

Broadly speaking, an employer 401(k) match means that if you invest money into your 401(k), your employer will put cash in, too. But these programs are often fairly nuanced.

While an annuity is also a contract between an individual and an insurance company, a life insurance policy differs in that it protects the beneficiaries in the event of the policyholder’s death.

Flexible spending accounts are operated by employers

Unlike health savings accounts, which can be opened at banks and credit unions, FSAs are employer-owned and operated—meaning you can only access an FSA through an employer benefit, and the account doesn't follow you if you move jobs. To use an FSA to pay for a medical service or product, purchases typically have to be uploaded, approved, and then employees can be reimbursed.
