IRA vs 401(k): 2026 Limits, Taxes, and How They Differ

IRA vs 401(k): 2026 Limits, Taxes, and How They Differ

The short answer on income limits for traditional IRA contributions in 2026 is that no income limit applies to contributing at all: anyone with earned income can put up to $7,500 ($8,600 at age 50 or older) into a Traditional IRA. What phases out with income is the tax deduction, and only when you or a spouse is an active participant in a workplace retirement plan (Source: IRS Pub 590-A; IRS Notice 2025-67).

There is no income limit to contribute to a Traditional IRA in 2026. If you have earned income, you can contribute up to $7,500, or $8,600 at age 50 or older. Income limits only the deduction: when you are covered by a workplace plan, the deduction phases out from $81,000 to $91,000 of MAGI (single) and $129,000 to $149,000 (married filing jointly), per IRS Notice 2025-67.

Is there an income limit to contribute to a Traditional IRA in 2026?

No. There is no income limit for traditional IRA contributions in 2026, and the query itself rests on a common misconception. Any person with taxable compensation can contribute to a Traditional IRA no matter how high their income, up to the annual limit. Income affects only whether the contribution is tax deductible (Source: IRS Pub 590-A).

The rule people are usually thinking of is the deduction phase-out. When you or your spouse is an active participant in a workplace plan such as a 401(k), the amount you can deduct falls as your modified adjusted gross income (MAGI) rises. The contribution stays legal; only the deduction shrinks (Source: IRS Pub 590-A).

This differs from the Roth IRA, where income can bar the contribution entirely. Keeping the two straight is the single most common point of confusion, and a later section places them side by side.

2026 Traditional IRA contribution limits

For 2026 the Traditional IRA contribution limit is $7,500, or $8,600 if you are age 50 or older, and it is capped at your taxable compensation for the year if that figure is lower. These amounts apply regardless of income and come from IRS Notice 2025-67. The limit is combined across all your Traditional and Roth IRAs, not per account.

2026 IRA contribution limit Amount
Under age 50 $7,500
Age 50 or older (with $1,100 catch-up) $8,600
Income limit to contribute None (earned income required)

To contribute you need taxable compensation such as wages, salary, or self-employment income. A married person with little or no earnings may still contribute through a spousal IRA if the couple files jointly and total compensation covers both contributions (Source: IRS Pub 590-A).

2026 Traditional IRA deduction income limits by filing status

The 2026 Traditional IRA deduction income limits depend on your filing status and on whether you or your spouse is an active participant in a workplace plan. Inside each MAGI phase-out range the deduction is partial; below the range it is full, and at or above the top it is zero. These figures come from IRS Notice 2025-67.

Filing status and workplace-plan coverage 2026 MAGI phase-out range Deduction outcome
Single or head of household, you are covered $81,000 to $91,000 Full below $81,000; partial inside; none at $91,000 or more
Married filing jointly, you are covered $129,000 to $149,000 Full below $129,000; partial inside; none at $149,000 or more
Married filing jointly, spouse is covered but you are not $242,000 to $252,000 Full below $242,000; partial inside; none at $252,000 or more
Married filing separately, you are covered $0 to $10,000 Partial inside; none at $10,000 or more
Neither you nor your spouse is covered No limit Full deduction at any income

The key phrase is active participant, which the IRS uses for someone covered by an employer plan. A box on your Form W-2 (the Retirement plan box) is checked when you are covered. If neither spouse is an active participant, the Traditional IRA contribution is fully deductible at any income level (Source: IRS Pub 590-A).

How to calculate a partial Traditional IRA deduction

Inside a phase-out range the deduction is prorated, and IRS Pub 590-A gives the method. You take the top of your phase-out range, subtract your MAGI, divide by the width of the range ($10,000 for most statuses, $20,000 for married filing jointly when you are the covered spouse), then multiply by your contribution limit. Round up to the nearest $10.

  1. Subtract your MAGI from the top of your phase-out range.
  2. Divide that result by $10,000, or by $20,000 for a married-filing-jointly filer who is the covered spouse.
  3. Multiply the fraction by your $7,500 or $8,600 contribution limit.
  4. Round the answer up to the nearest $10. If it comes out above $0 but under $200, you may still deduct $200 (Source: IRS Pub 590-A).

Example: a single active participant, age 45, with $85,000 MAGI. The top of the range is $91,000, so $91,000 minus $85,000 is $6,000. Dividing $6,000 by $10,000 gives 0.60, and 0.60 times $7,500 is $4,500. The deductible amount is $4,500; the remaining $3,000 can still be contributed as a nondeductible contribution.

What to do when your Traditional IRA contribution is not deductible

When your income places you above the deduction phase-out, you can still contribute to a Traditional IRA; the contribution is simply nondeductible. You report it on IRS Form 8606, which tracks your basis (the after-tax money in your IRA) so that portion is not taxed again at withdrawal. Filing Form 8606 for the year of each nondeductible contribution is what preserves that basis.

A nondeductible contribution is also the first step in a backdoor Roth, where the after-tax Traditional IRA amount is converted to a Roth IRA. The pro-rata rule aggregates all your Traditional, SEP, and SIMPLE IRA balances when figuring the taxable share of any conversion, so pre-tax IRA money can create tax. This mechanics overlaps with a full Roth conversion, and deciding how much to convert to Roth depends on your whole IRA picture.

Because conversions add to taxable income, they can interact with other thresholds such as the net investment income tax and future required minimum distributions. Many savers coordinate the timing across years rather than acting in isolation.

Traditional IRA deduction limits vs Roth IRA contribution limits

Savers frequently confuse the Traditional IRA deduction limits with the separate Roth IRA contribution limits, and the two work differently. Above the Traditional range you lose the deduction but keep the ability to contribute. Above the Roth range you lose the ability to contribute at all. The 2026 figures below come from IRS Notice 2025-67.

Filing status Traditional IRA deduction phase-out (if covered) Roth IRA contribution phase-out
Single or head of household $81,000 to $91,000 $153,000 to $168,000
Married filing jointly $129,000 to $149,000 $242,000 to $252,000
Married filing separately $0 to $10,000 $0 to $10,000
What phases out The deduction (you can still contribute) The ability to contribute at all

A saver above the Roth range but who wants Roth exposure often uses the backdoor Roth path described above. A saver above the Traditional deduction range can contribute nondeductibly and track basis on Form 8606 (Source: IRS Pub 590-A).

Frequently asked questions

Is there an income limit to contribute to a Traditional IRA?

No. There is no income limit to contribute to a Traditional IRA in 2026. Anyone with taxable compensation can contribute up to $7,500, or $8,600 at age 50 or older, no matter how high their income. Income affects only whether the contribution is deductible, not whether you can make it (Source: IRS Pub 590-A; IRS Notice 2025-67).

Can I contribute to a Traditional IRA if I have a 401(k)?

Yes. Having a 401(k) does not stop you from contributing to a Traditional IRA in 2026. Being covered by that workplace plan (an active participant) can reduce or eliminate your deduction once your MAGI enters the phase-out range, but the $7,500 or $8,600 contribution itself is always allowed (Source: IRS Pub 590-A).

What is the Traditional IRA deduction income limit for 2026?

For 2026, if you are covered by a workplace plan, the deduction phases out from $81,000 to $91,000 of MAGI for single filers and $129,000 to $149,000 for married filing jointly. If your spouse is covered but you are not, the range is $242,000 to $252,000. Married filing separately phases out from $0 to $10,000 (Source: IRS Notice 2025-67).

Can I deduct my Traditional IRA contribution if I am covered by a retirement plan at work?

It depends on your MAGI. If you are an active participant in a workplace plan in 2026, a full deduction applies below your phase-out range, a partial deduction applies inside it, and no deduction applies at or above the top. A single filer covered at work loses the deduction at $91,000 of MAGI (Source: IRS Pub 590-A).

What happens if I contribute to a Traditional IRA but make too much to deduct it?

The contribution is still allowed; it is simply nondeductible. You report it on IRS Form 8606 to track your basis so that after-tax amount is not taxed again at withdrawal. Many savers in this position use the nondeductible contribution as the first step of a backdoor Roth, mindful of the pro-rata rule (Source: IRS Pub 590-A).

What is the income limit for a Traditional IRA if I am married filing jointly in 2026?

There is no income limit to contribute when married filing jointly. For the deduction in 2026, if you are the covered spouse the phase-out runs from $129,000 to $149,000 of MAGI. If your spouse is covered but you are not, it runs from $242,000 to $252,000. If neither spouse is covered, the deduction is full at any income (Source: IRS Notice 2025-67).

Do Traditional IRA income limits apply if my spouse has a 401(k) but I don’t?

Yes, but at a higher threshold. If you are not an active participant yet your spouse is covered by a workplace plan, your 2026 Traditional IRA deduction phases out from $242,000 to $252,000 of joint MAGI. Below $242,000 you can deduct the full contribution; at $252,000 or more the deduction is gone (Source: IRS Pub 590-A).

How much can I contribute to a Traditional IRA in 2026?

For 2026 you can contribute up to $7,500 to a Traditional IRA, or $8,600 if you are age 50 or older, limited to your taxable compensation if that is lower. This limit is shared across your Traditional and Roth IRAs combined and is set by IRS Notice 2025-67. It applies at any income level.
