IRA vs. 401(k)

Check the background of investment professionals associated with this site on FINRA's BrokerCheck.

In 2021, just 60 million Americans had a 401(k),¹ while around one-third of households owned an individual retirement account (IRA).² Yet for as commonplace as these retirement accounts can be, the nuances of contributions can be more complex.

401(k) vs. IRA: The Basics

There are several key differences between these two kinds of retirement accounts, and your unique circumstances often will dictate whether you contribute to a 401(k), an IRA or both.

Contribution limits

For 2025, those age 50 and older can contribute $31,000 to a 401(k) or $8,000 to an IRA; those age 49 and younger can contribute $23,500 to a 401(k) or $7,000 to an IRA.³

Under the SECURE 2.0 Act that was enacted starting in tax year 2023, a higher catch-up contribution limit applies for employees aged 60-63 who participate in these retirement plans. For 2025, the higher catch-contribution limit is $11,250 instead of $8,000.

Portability

Because the "I" in IRA stands for "individual," these retirement accounts are portable—you do not need to withdraw or transfer the funds when you change jobs, and you are free to choose any IRA custodian you wish. On the other hand, 401(k)s are generally tied to one's employer; when you leave that position, you may be required to roll over your 401(k) into an IRA or your new employer's 401(k) if they offer one.

Investment options

With a 401(k), retirement savers are limited to the investment funds and indices the plan provides. Sometimes, these options can be limited. With an IRA, account holders can choose their retirement custodian, which generally opens up access to a broader range of investment options.

Tax treatment

IRAs can be divided into two categories: a traditional IRA, where pre-tax contributions are tax-deductible, or a Roth IRA, where contributions are made post-tax. At retirement, someone who withdraws funds from a traditional IRA will need to pay taxes on their withdrawal; with Roth accounts, the taxes have already been paid and so the withdrawals are tax-free. Some 401(k)s also have a Roth option, allowing the account holder to contribute post-tax funds in exchange for tax-free retirement assets.³

Which Account Should You Contribute to First?

If you have a 401(k) available through your employer, you can contribute to both it and any IRA at the same time, for a maximum contribution of $30,000 per year. For those aged 50 or greater, however, the contribution limit is $39,000, and due to the SECURE 2.0 Act, those aged 60-63 can contribute up to $42,750.³

If you cannot afford to max out both accounts, you may want to consider the below framework to try and get the most bang for your buck.

First, determine whether your employer offers a match for 401(k) contributions. Any matching funds do not count against your own contributions and aren't taxed, essentially making them "free money."⁴ If your employer matches, it often makes sense to contribute to this account at least enough to get the full available match. Savers may then want to consider contributing to an IRA, then returning to 401(k) contributions once the IRA has been maxed.

If your employer does not offer a company match, it may make more sense to begin your retirement savings with either a traditional or Roth IRA, since these accounts tend to have lower fees and more investment options.⁵ And for those who are in a relatively low tax bracket, paying these taxes on IRA contributions now (and avoiding them in retirement) may minimize their overall tax burden.⁶

Because the decision whether to contribute to an IRA, a 401(k) or both is a highly individualized one, it is a good idea to talk it over with a financial advisor before taking the plunge.
