Can You Max Out Both 401(k) and IRA in the Same Year?

Yes. You can max out both a 401(k) and an IRA in the same year, because the IRS treats them as separate retirement vehicles and contributing to one does not disqualify you from the other.¹ For 2026, that adds up to $24,500 in 401(k) salary deferrals plus $7,500 across your IRAs, or $32,000 in personal contributions — more if you qualify for catch-ups.² Whether your IRA piece is tax-deductible or Roth-eligible is a separate question that turns on your income and your workplace plan status.

The 2026 401(k) Cap

The most you can defer from your paycheck into a 401(k) in 2026 is $24,500.² That cap belongs to you, not to the plan: if you work for two employers during the year, your combined deferrals across both plans still cannot exceed $24,500.³ The same cap covers your combined pre-tax and designated Roth 401(k) deferrals, so you cannot put $24,500 into each type.⁴

If you turn 50 by the end of the year, you can add $8,000 in catch-up contributions, for a personal cap of $32,500.⁵ A larger SECURE 2.0 catch-up applies if you are 60, 61, 62, or 63: $11,250 in 2026, which raises the personal cap to $35,750.²

Employer matching and profit-sharing dollars sit outside your deferral cap but count toward a broader annual ceiling. In 2026, everything going into your account, your deferrals plus employer money, cannot exceed $72,000 or 100 percent of your compensation, whichever is less.⁶

The 2026 IRA Cap

The most you can put into all of your IRAs combined, Traditional and Roth together, is $7,500 for 2026.² You can split that amount between the two types in any proportion, but the total is one shared limit, not one per account.⁷

At age 50, SECURE 2.0 now indexes the IRA catch-up for inflation. For 2026, the catch-up is $1,100, taking your IRA cap to $8,600.² Your contribution also cannot exceed your earned income for the year. If you earned $5,000, that is your ceiling regardless of the statutory number.⁸

Will Your Traditional IRA Contribution Be Deductible?

This is where maxing both accounts gets complicated. Anyone with earned income can contribute to a Traditional IRA, but if you (or your spouse) are covered by a workplace retirement plan, your ability to deduct that contribution phases out at higher incomes. Your W-2 shows a checkmark in the “Retirement plan” box when your employer treats you as an active participant, which almost anyone contributing to a 401(k) will be.

For 2026, the deduction phases out on these Modified Adjusted Gross Income ranges:²

Single filer covered by a workplace plan: full deduction below $81,000 MAGI, partial between $81,000 and $91,000, none above $91,000.
Married filing jointly, contributing spouse covered: full deduction below $129,000, partial between $129,000 and $149,000, none above $149,000.
Married filing jointly, contributing spouse not covered but the other spouse is: full deduction below $242,000, partial between $242,000 and $252,000, none above $252,000.

If neither spouse is covered by a workplace plan, you can deduct your full Traditional IRA contribution at any income level.

Even when you earn too much to deduct, you can still make a non-deductible Traditional IRA contribution. The money grows tax-deferred, but there is no upfront tax break, and you must file Form 8606 with your return to track the after-tax basis so you are not taxed on it again at withdrawal.⁹ Skipping the form triggers a $50 penalty.

Roth IRA Income Limits

Direct Roth IRA contributions phase out based on income no matter what your workplace plan looks like. For 2026:²

Single or head of household: full contribution below $153,000 MAGI, reduced between $153,000 and $168,000, none above $168,000.
Married filing jointly: full contribution below $242,000, reduced between $242,000 and $252,000, none above $252,000.

If you overcontribute because your income lands higher than expected, you can recharacterize the excess Roth contribution as a Traditional IRA contribution. Tell your custodian to move the amount plus any associated earnings before your tax-filing deadline (including extensions), and the IRS treats the money as if it had gone into the Traditional IRA from the start.¹

Backdoor Roth When Income Is Too High

If your income closes the door on direct Roth contributions, a two-step “backdoor” Roth may still get you there. You make a non-deductible contribution to a Traditional IRA (no income limit applies) and then convert that balance to a Roth. Because the contribution was already after-tax, the conversion itself generally produces little or no additional tax, as long as you move quickly before the money earns much.

The pitfall is the pro-rata rule. When you convert, the IRS looks at the combined balance of all your Traditional, SEP, and SIMPLE IRAs and calculates what percentage is pre-tax versus after-tax.¹⁰ If 80 percent of the total is pre-tax, then 80 percent of any conversion is taxable, even if the specific account you are converting holds only after-tax dollars. The strategy works cleanest when your pre-tax IRA balances are zero at conversion time. A common workaround is rolling existing pre-tax IRA money into your employer’s 401(k) first, if that plan accepts incoming rollovers. Both the non-deductible contribution and the conversion are reported on Form 8606.⁹

Doubling Up With a Spousal IRA

If one spouse earns income and the other does not, the working spouse can fund an IRA for the non-earning spouse, provided the couple files jointly. Total contributions for both spouses cannot exceed their combined earned income for the year.⁸ Each spouse holds their own IRA; the accounts cannot be held jointly.¹¹ Both can contribute up to the full $7,500 for 2026 (or $8,600 at 50 and older), taking household IRA savings to as much as $15,000 or $17,200.

The Two Deadlines Are Different

401(k) contributions come out of payroll, so they must be made by December 31 of the calendar year. There is no grace period. If you want to hit the full $24,500 for 2026, the money has to leave your pay during 2026.¹² Check your deferral percentage early enough that the target is reached before your final paycheck.

IRA contributions are more forgiving. You have until the tax-filing deadline, typically April 15 of the following year, to contribute for the prior tax year.¹³ A 2026 IRA contribution can be made anytime between January 1, 2026, and April 15, 2027. When you send the money, confirm your custodian codes it for the correct tax year.

If You Contribute Too Much

Excess IRA contributions carry a 6 percent excise tax on the extra amount for every year it stays in the account.¹⁴ The penalty repeats annually until you fix it. To avoid the tax, withdraw the excess plus any earnings on it before your tax-filing deadline, including extensions.¹³ The earnings portion of that withdrawal is taxable in the year the contribution was made.

On the 401(k) side, the main way to overshoot is working for two employers in the same year. Each plan’s payroll system operates independently and does not know what you deferred elsewhere. If your combined deferrals exceed $24,500 (or your catch-up amount), contact one plan administrator before April 15 of the following year and request a return of the excess.³ If the excess is not returned on time, it can end up taxed twice: once in the year deferred and again when eventually distributed.
