Key takeaways
- For 2026, employees can contribute up to $24,500 to a 401(k) and $7,500 to an IRA, with higher catch-up limits from age 50.
- A 401(k) exists only if your employer offers one; anyone with earned income can open an IRA.
- Employer matching contributions, where offered, can add money to a 401(k) that an IRA cannot match.
- IRAs generally let you pick from more investments, while a 401(k) restricts you to the menu your plan provides.
- You can contribute to both accounts in the same year, subject to the separate limits on each.
Most retirement saving happens through one of two accounts: the 401(k) offered at work and the individual retirement account, or IRA, you open yourself. They do a similar job, sheltering your money from tax while it grows, but they differ on limits, control, and who sets the rules. Here is a side-by-side look at where each one does its best work.
The Core Difference in One Paragraph
A 401(k) is an employer-sponsored plan. It exists only if your employer offers one, contributions come out of your paycheck before you see the money, and a written plan document governs the matching formula, the investment menu, and the withdrawal rules. An IRA is an account you open on your own at a bank, mutual fund company, or brokerage firm, as long as you have earned income. That single distinction drives most of the others: workplace plans tend to allow higher contributions and can include employer money, while IRAs tend to offer wider investment choice and more personal control.
Contribution Limits: How Much Each Account Accepts
The 401(k) accepts far more each year. For 2026, the employee contribution limit for 401(k) plans is $24,500, up from $23,500 for 2025. The IRA limit for 2026 is $7,500, up from $7,000.
Catch-up contributions widen the gap for older savers. Workers aged 50 and over can add $8,000 to a 401(k) in 2026, for a total of $32,500, while the IRA catch-up for the same age group is $1,100, for a total of $8,600. Under a change made by the SECURE 2.0 Act, employees aged 60, 61, 62, and 63 get a higher 401(k) catch-up of $11,250 for 2026.
One IRA detail to keep in mind: the $7,500 limit covers all the IRAs you own added together, rather than applying to each account separately. If you hold a traditional IRA and a Roth IRA, what you put into both over the year cannot top $7,500.
The Employer Match: Why It Changes the Math
Many 401(k) plans include employer matching contributions. A match is employer money paid into your account in proportion to what you put in, typically capped at some share of your salary. The IRS gives a simple example: 50 cents for each dollar the employee defers. Some matches are discretionary, meaning the company can skip them in some years, while safe harbor 401(k) plans require a minimum employer contribution. Employer contributions can also be subject to a vesting schedule, which means you gain a permanent right to that money only after a period of service.
An IRA has no equivalent. No outside party adds money based on what you contribute, so the account grows only from your own deposits and investment returns. For workers whose employers offer a match, that matched money is the strongest argument for using the workplace plan at least up to the match, because it is compensation already on offer.
Money tip: If your employer matches 401(k) contributions, check your plan document for the formula and the vesting schedule before deciding where your next retirement dollar goes.
Investment Options and Fees Compared
A 401(k) limits you to the investments your employer’s plan offers, typically a menu that can include stocks, bonds, mutual funds, money market funds, and savings accounts. An IRA can generally be opened at many financial institutions, and IRAs usually open up a broader set of investments than the typical workplace plan provides, along with more personal control over what you hold.
That flexibility has a trade-off: with an IRA, the choices and their costs are yours to research. In a 401(k), the menu is smaller but curated, and plan fiduciaries are responsible under federal law for managing the plan in participants’ interests. Fees and investment costs vary by plan and by provider in both cases, so compare what each account charges before deciding where to direct your savings.
Access and Flexibility: Withdrawals and Moving Money
The two accounts handle access differently. In a 401(k), withdrawal provisions, and any plan-specific features, are set by the plan document, so the details depend on your employer’s plan. When you leave a job, a 401(k) may allow you to take your benefits with you, often by rolling the balance into another retirement account.
With an IRA, the rules come from tax law and your account agreement rather than an employer. In both account types, pulling money out early can carry tax consequences, and Roth accounts only deliver their tax-free treatment on qualified distributions from accounts held at least five years. Whatever the account rules allow, retirement money is generally the wrong home for cash you might need on short notice; a separate emergency fund serves that purpose.
Tax Treatment: Both Come in Traditional and Roth Flavors
Both account types split into two tax treatments. Traditional versions take contributions before tax or make them tax-deductible, and withdrawals in retirement are taxed as income. Roth versions take contributions as after-tax money, and qualified withdrawals, including earnings, come out tax-free. If you are weighing the two versions inside a workplace plan, our comparison of the Roth 401(k) and the traditional 401(k) walks through the trade-offs.
The traditional IRA has one wrinkle the 401(k) does not: if you or your spouse is covered by a retirement plan at work, the deduction for traditional IRA contributions is reduced or eliminated as income rises. For 2026, the phase-out range is $81,000 to $91,000 for a single taxpayer covered by a workplace plan, and $129,000 to $149,000 for a married couple filing jointly when the contributing spouse is covered. If neither spouse is covered by a workplace plan, the phase-out does not apply. Direct Roth IRA contributions also have income limits, so check the current IRS figures for your filing status.
Using Both: How the Accounts Work Together
The two accounts are not rivals. You can contribute to both in the same year, and each account is subject to its own limit under IRS rules, so the amount you put in one does not reduce what you can put in the other. Some savers use a layered approach: contribute enough to the 401(k) to capture the full match, then put additional savings into an IRA for its wider investment choice.
Each option suits a different situation. The 401(k) suits workers whose employers offer one, especially with a match. The IRA suits anyone with earned income, including workers whose employers offer no plan, and savers who want more say over their investments. Using both suits those who have filled the match and want to save more in tax-advantaged accounts. For decisions about your own mix, the plan documents and the IRS explain the rules, and a qualified financial or tax professional can account for your full situation.
| Feature | 401(k) | IRA |
|---|---|---|
| Who can open one | Only through an employer that offers the plan | Anyone with earned income |
| 2026 employee contribution limit | $24,500 | $7,500 |
| 2026 catch-up, age 50 and over | $8,000 (total $32,500); $11,250 at ages 60 to 63 | $1,100 (total $8,600) |
| Employer match | Common, up to the plan’s formula and vesting rules | None |
| Investment choice | Limited to the plan’s menu | Generally wider, chosen by you |
| Tax versions | Traditional and Roth, if the plan offers both | Traditional and Roth |

Common questions
Q: Can I contribute to a 401(k) and an IRA in the same year?
A: Yes. The two accounts have separate contribution limits, so you can use both. If you are covered by a workplace plan, the deduction for traditional IRA contributions may be reduced or eliminated depending on your income and filing status.
Q: Which account has the higher contribution limit?
A: The 401(k). For 2026, the employee contribution limit is $24,500 for a 401(k) and $7,500 for an IRA. Catch-up contributions for savers 50 and older are also larger in the 401(k).
Q: Do I lose my employer match if I also fund an IRA?
A: No. Matching depends on your own 401(k) contributions, not on what you put in an IRA. If your plan offers a match, check the plan document for the formula and any vesting schedule.
Q: Which account is better for someone whose employer offers no plan?
A: An IRA is typically the only one of the two available, since a 401(k) can only be opened through an employer. Anyone with earned income can open an IRA at a bank, mutual fund company, or brokerage firm.
