Yes, you can have both an IRA and a 401(k) in the same year. The IRS confirms that participating in an employer-sponsored retirement plan does not prevent you from also funding an Individual Retirement Account.1Internal Revenue Service. Retirement Plans FAQs Regarding IRAs For 2026, that means up to $24,500 into a 401(k) and up to $7,500 into an IRA, for a combined personal savings total of $32,000 before catch-up contributions.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The real questions are how much of your IRA contribution you can deduct, whether you qualify for a Roth, and how the two accounts interact when you eventually take the money out.
How Much You Can Contribute in 2026
Each account has its own limit, and money in one does not reduce room in the other. The 2026 employee deferral cap for a 401(k) is $24,500. If you are 50 or older, a catch-up of $8,000 raises your possible deferral to $32,500. If you turn 60, 61, 62, or 63 during 2026, a “super catch-up” of $11,250 replaces the standard catch-up, bringing the 401(k) maximum to $35,750.3Internal Revenue Service. COLA Increases for Dollar Limitations on Benefits and Contributions
The 2026 IRA limit is $7,500, with a $1,100 catch-up for those 50 or older, for a maximum of $8,600.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The IRA catch-up is now indexed for inflation under SECURE 2.0, which is why it moved off the long-standing $1,000. The IRA limit applies across all your traditional and Roth IRAs combined, not per account.
Employer contributions to your 401(k) do not eat into your $24,500 employee cap, but they do count toward a separate overall ceiling. For 2026, deferrals plus employer matching and profit-sharing cannot exceed $72,000, or $80,000 and $83,250 with the standard and super catch-ups.4Internal Revenue Service.

Will Your Traditional IRA Contribution Be Deductible?
Having a 401(k) does not stop you from contributing to a traditional IRA. It can limit whether you get a deduction for it. The trigger is whether you count as an “active participant” in a workplace plan; your employer marks that on your W-2, and if the box is checked, income-based phase-outs apply.
The 2026 deduction phase-outs for someone covered by a 401(k):
- Single or head of household: full deduction with modified adjusted gross income (MAGI) of $81,000 or less, partial from $81,000 to $91,000, none above $91,000.
- Married filing jointly (you have the 401(k)): full deduction with joint MAGI of $129,000 or less, partial from $129,000 to $149,000, none above $149,000.
- Married filing separately: partial deduction below $10,000, none at $10,000 or more.
These figures come from the annual IRS cost-of-living adjustments.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
Above the upper threshold, you can still make a nondeductible contribution to a traditional IRA. You lose the upfront tax break but keep tax-deferred growth. Report the nondeductible portion on Form 8606; that form tracks your after-tax basis so the same dollars are not taxed again when distributed.5Internal Revenue Service. About Form 8606, Nondeductible IRAs
Roth IRA Eligibility
Roth IRAs use after-tax dollars, and qualified withdrawals (including growth) come out tax-free. Whether you can contribute directly depends on income, not on whether you have a 401(k).
Direct Roth contributions in 2026:4Internal Revenue Service. IRS Notice 2025-67 – 2026 Amounts Relating to Retirement Plans and IRAs
- Single or head of household: full contribution below $153,000, reduced from $153,000 to $168,000, none at $168,000 or above.
- Married filing jointly: full contribution below $242,000, reduced from $242,000 to $252,000, none at $252,000 or above.
- Married filing separately: reduced contribution below $10,000, none at $10,000 or more.
In the phase-out range, the IRS reduces your allowable contribution proportionally: your excess income above the lower threshold, divided by the width of the range, then subtracted from the full limit. Overshoot the allowed amount and you owe a 6% excise tax on the excess for every year it stays in the account.6Office of the Law Revision Counsel. 26 U.S.C. 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities
High earners who exceed these limits sometimes use a “backdoor Roth,” which means making a nondeductible traditional IRA contribution and then converting it to a Roth. There is no income cap on conversions. The complication is the pro-rata rule: the IRS treats all your traditional IRA balances as one pool and taxes the conversion based on the ratio of pre-tax to after-tax money across every traditional IRA you hold.7Internal Revenue Service. Transcript for the Basics of Roth Conversions If you have $100,000 of pre-tax IRA money and convert a $7,500 nondeductible contribution, roughly 93% of the conversion is taxable. Rolling existing pre-tax IRA balances into your 401(k) (if the plan accepts incoming rollovers) zeroes out that pool and keeps the conversion clean. The whole transaction is reported on Form 8606.8Internal Revenue Service. Instructions for Form 8606
Spousal IRA if Only One of You Works
A working spouse can fund an IRA for a nonworking partner as long as the couple files jointly. Combined contributions to both spouses’ IRAs cannot exceed the taxable compensation on the joint return.9Internal Revenue Service. Retirement Topics – IRA Contribution Limits That effectively doubles the household’s IRA capacity on a single income.
Deduction rules for the nonworking spouse are more generous. Because that spouse is not covered by a workplace plan, only the working spouse’s coverage matters. If the working spouse has a 401(k), the nonworking spouse’s traditional IRA deduction phases out between $242,000 and $252,000 of joint MAGI in 2026.4Internal Revenue Service. IRS Notice 2025-67 – 2026 Amounts Relating to Retirement Plans and IRAs If neither spouse has a workplace plan, there is no income limit on the deduction.
Why Holding Both Accounts Matters at Withdrawal
The two account types are not interchangeable when you take money out. That is part of the reason having both is useful.
Before age 59½, distributions from either type generally trigger a 10% penalty on top of income tax, but the exceptions differ. IRAs allow penalty-free early withdrawals for qualified higher education expenses, up to $10,000 (lifetime) for a first-time home purchase, and for health insurance premiums after receiving unemployment compensation for at least 12 weeks. None of those apply to 401(k) distributions.10Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
The 401(k) offers its own exception. If you leave your job in or after the year you turn 55 (50 for certain public safety employees), you can withdraw from that employer’s plan without the 10% penalty. That “separation from service” rule does not apply to IRAs.10Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Rolling a 401(k) balance to an IRA too early can cost you access to this exception, so the choice to roll or leave money in a plan is worth thinking through.
Required minimum distributions (RMDs) also work differently. RMDs begin at age 73 for people born between 1951 and 1959, and at age 75 for those born in 1960 or later.11Internal Revenue Service. 12Internal Revenue Service. RMD Comparison Chart (IRAs vs. Defined Contribution Plans) Roth IRAs have no RMDs during the owner’s lifetime, which makes them useful for anyone who does not need the income in retirement.
If You Contribute Too Much
The correction rules for excess contributions are strict, and they differ by account.
On the 401(k) side, excess deferrals above $24,500 (or the applicable catch-up) must be returned to you with earnings by April 15 of the following year. Meet that deadline and the returned amount is taxed only once, in the year of deferral, with no 10% penalty. Miss it and the excess is taxed twice: once in the contribution year and again when it eventually leaves the plan.13Internal Revenue Service. Consequences to a Participant Who Makes Excess Deferrals to a 401(k) Plan This trips up people who change jobs mid-year and contribute to two different employer plans.
Excess IRA contributions carry a 6% excise tax each year the excess remains in the account.14Internal Revenue Service. IRA Excess Contributions You can avoid the penalty by withdrawing the excess plus attributable earnings before your tax filing deadline, including extensions. After filing, you can apply the excess toward the next year’s limit, but the 6% still applies for the year it sat in the account.
