IRA Tax Deduction Income Limits and Phase-Out Ranges

Whether your Traditional IRA contribution is deductible depends on three things: your filing status, whether you or your spouse is covered by a workplace retirement plan, and your modified adjusted gross income. The IRA tax deduction income limits for 2026 only bite when someone in the household has a plan at work. If neither spouse does, you can deduct the full contribution at any income level. If someone is covered, a phase-out range applies, and the range is very different depending on who is covered and how you file.¹

Which Situation Applies to You

Find yourself in one of these four buckets before looking at any numbers. The rules are wildly different across them, and the most common mistake is applying the wrong range.

You are covered by a workplace retirement plan.
You are not covered, but your spouse is.
Neither of you is covered.
You are married and filing separately.

“Covered” is a term of art. You count as covered if your employer made contributions on your behalf or allocated forfeitures to your account during the year, even if you personally contributed nothing. The reliable test is Box 13 on your Form W-2: if the “Retirement plan” box is checked, you’re covered for the year.²

If You Have a Workplace Retirement Plan

When you actively participate in an employer plan such as a 401(k), 403(b), or pension, the IRS narrows your deduction based on MAGI. The 2026 phase-out ranges:³

Single or head of household: full deduction at or below $81,000 MAGI, partial deduction between $81,000 and $91,000, no deduction at $91,000 or above.
Married filing jointly: full deduction at or below $129,000 MAGI, partial deduction between $129,000 and $149,000, no deduction at $149,000 or above.

If Only Your Spouse Has a Workplace Plan

When you don’t have your own workplace retirement plan but your spouse does, a much more generous joint limit applies. For 2026, joint filers in this situation get a full deduction with MAGI up to $242,000. The deduction phases out between $242,000 and $252,000 and disappears above $252,000.³

Plenty of dual-income couples land here without noticing, because only one employer offers a plan. Check both W-2s.

If Neither of You Has a Workplace Plan

Income limits don’t apply. You can earn any amount and still deduct the full Traditional IRA contribution.¹ Confirm it by checking Box 13 on both spouses’ W-2 forms. If neither shows a checkmark next to “Retirement plan,” you’re in the clear.²

This bucket is bigger than people expect. Self-employed individuals who haven’t set up a SEP-IRA or solo 401(k), employees at small companies without retirement benefits, and freelancers all typically qualify.

If You Are Married Filing Separately

Married couples who file separate returns face the harshest limits in the entire IRA deduction structure. If either spouse is covered by a workplace plan and you lived together at any point during the year, the phase-out range is $0 to $10,000. That range is not adjusted for inflation. At a MAGI of just $10,000, the deduction drops to zero.³

One narrow exception: if you filed separately and did not live with your spouse at any time during the year, you’re treated as a single filer for IRA deduction purposes, with the $81,000 to $91,000 phase-out range. If you shared a home even briefly, the $0 to $10,000 range applies.

Figuring Your MAGI

MAGI is the number that decides where you land in a phase-out range. Start with the adjusted gross income on line 11 of your Form 1040, then add back certain items. For IRA deduction purposes, the add-backs are the student loan interest deduction, the foreign earned income exclusion, the foreign housing deduction, excluded savings bond interest, and excluded employer-provided adoption benefits.⁴

If none of those apply to you, your MAGI equals your AGI. If any do apply, skipping the add-back can make your MAGI look lower than it really is and lead you to claim a larger deduction than you’re entitled to.

Calculating a Partial Deduction

Landing inside a phase-out range means you lose a proportional slice of the deduction, not the whole thing. Take the upper limit of your range, subtract your MAGI, and divide by the size of the range. Multiply that fraction by the annual contribution limit to get your deductible amount. IRS Publication 590-A includes Worksheet 1-2 for the exact calculation.⁴

A single filer covered by a workplace plan with a 2026 MAGI of $86,000 sits halfway through the $81,000–$91,000 range, so roughly half the maximum contribution would be deductible. The IRS rounds partial deduction amounts up to the nearest $10, and the minimum partial deduction is $200. If the formula produces anything between $1 and $199, you get $200.

What if You’re Above the Limit?

Being above the phase-out range doesn’t stop you from contributing. It just means you won’t get a deduction for the money you put in. The contribution still grows tax-deferred, which has value on its own, but you have to track those non-deductible contributions or you’ll end up paying tax on the same dollars twice.

That tracking happens on Form 8606, filed with your Form 1040 for any year you make non-deductible Traditional IRA contributions or take distributions from an IRA that contains non-deductible money. The form keeps a running total of your basis, the after-tax dollars you’ve put in, so that when you eventually take distributions the IRS can tell how much of each withdrawal is taxable. Missing a required Form 8606 filing carries a $50 penalty, and losing track of basis can cost you far more at withdrawal.⁵
