Traditional IRA deduction limits
Last updated August 2026
Short answer
The single most common misreading is treating these numbers as contribution limits. They are not. They decide the tax treatment of a contribution you are allowed to make either way.
The 2026 ranges
Single or head of household, covered by a workplace plan: the deduction phases out between $81,000 and $91,000 of modified AGI.
Married filing jointly, where the person contributing is covered: $129,000 to $149,000.
Married filing jointly, where the contributor is not covered but the spouse is: $242,000 to $252,000. Married filing separately while covered: $0 to $10,000, a range that does not move with inflation.
The coverage question comes first
If neither you nor your spouse participated in a workplace plan during the year, no phase-out applies at all and income is irrelevant.
Coverage means participation, not eligibility. For a defined contribution plan, it turns on whether contributions were actually made to your account during the year.
Your W-2 carries a retirement plan indicator, which is the quickest way to settle it before doing any arithmetic.
How the phase-out actually works
Income inside the range reduces the deduction proportionally rather than removing it. It is a slope, not a cliff.
At the midpoint, roughly half the contribution is deductible, and the result is rounded up to the nearest $10 with a $200 minimum where any deduction is available.
Publication 590-A carries the worksheet, and most tax software runs it without being asked.
Try it in Walnut
Walnut connects to your brokerage and shows your IRA next to everything else you own, which is the view that makes an asset location decision possible.
When you cannot deduct
The contribution is still allowed. It becomes basis, meaning money already taxed, and is reported on Form 8606 for the year it is made.
Keep those forms permanently. They are the evidence that stops the same dollars being taxed a second time on withdrawal, sometimes decades later.
Whether a non-deductible Traditional IRA contribution is worth making at all depends on the alternatives: a Roth contribution, if you are under those limits, is generally the better instrument.
The backdoor Roth connection
A non-deductible contribution followed by a conversion to Roth is the standard route for people above the Roth income limits.
The obstacle is the pro-rata rule: conversions are treated as coming proportionally from all your pre-tax and after-tax IRA balances combined.
Someone with a large rollover IRA will find most of the conversion taxable, which is why this manoeuvre is straightforward for some people and expensive for others.
Whether to contribute anyway
Above the phase-out, a Roth IRA contribution is generally better than a non-deductible traditional one, if income permits it.
Above the Roth limits too, the non-deductible contribution is mainly useful as the first step of a backdoor conversion.
Holding non-deductible money in a traditional IRA indefinitely gives you tax-deferred growth on the earnings and paperwork for the rest of your life, which is a modest benefit for a real cost.

FAQ
What are the 2026 Traditional IRA deduction limits?
+
If you are covered by a workplace plan, the deduction phases out between $81,000 and $91,000 of modified AGI for single filers, and between $129,000 and $149,000 for married filing jointly. If you are not covered but your spouse is, the range is $242,000 to $252,000.
What if neither of us has a workplace plan?
+
Then the deduction is fully available at any income. The phase-outs exist only because a workplace plan already provides tax-advantaged saving, so without one there is nothing to limit.
What counts as covered by a workplace plan?
+
Participating in an employer plan during the year, which for a defined contribution plan means money was actually added to your account, by you or the employer. Your W-2 has a retirement plan box that indicates it.
What is modified AGI here?
+
Adjusted gross income with certain items added back, including student loan interest and foreign earned income exclusions, and calculated before the IRA deduction itself. It is usually close to AGI for most filers.
What happens inside the phase-out range?
+
The deduction shrinks proportionally rather than disappearing at a cliff. Halfway through the range, roughly half the contribution is deductible, and the calculation is on the worksheet in Publication 590-A.
Can I still contribute if I cannot deduct?
+
Yes. The income limits govern the deduction only. A non-deductible contribution becomes basis in the account, reported on Form 8606, so it is not taxed again when withdrawn.
Why does married filing separately have such a low range?
+
The $0 to $10,000 range for a covered filer is not adjusted for inflation and has been fixed for decades. It is one of several provisions that make filing separately expensive for retirement savers.
If I cannot deduct, should I contribute anyway?
+
Usually a Roth IRA is the better home for that money if your income permits it. Above the Roth limits too, a non-deductible traditional contribution is mainly useful as the first step of a backdoor conversion rather than as a long-term holding.
