How the Traditional IRA Deduction Phaseout Works
If you (or your spouse) are covered by an employer-sponsored retirement plan, your Traditional IRA deduction phases out at higher income levels. If neither you nor your spouse participates in an employer plan, your contribution is fully deductible regardless of income.
The Formula
Full Limit = $7,000 (or $8,000 if age 50+)
Deductible = Full Limit × (Upper Phaseout − MAGI) / Phaseout Range
Rounded to nearest $10 (minimum $200 if between $0–$200)
Non-Deductible Basis = Actual Contribution − Deductible Amount
Report non-deductible contributions on Form 8606
Deductible = Full Limit × (Upper Phaseout − MAGI) / Phaseout Range
Rounded to nearest $10 (minimum $200 if between $0–$200)
Non-Deductible Basis = Actual Contribution − Deductible Amount
Report non-deductible contributions on Form 8606
Example
Single, age 40, MAGI $84,000, covered by 401k (2026):
Full limit: $7,000 | Phaseout: $79,000 – $89,000
MAGI over lower limit: $84,000 – $79,000 = $5,000
Reduction: $7,000 × ($5,000 / $10,000) = $3,500
Deductible: $7,000 – $3,500 = $3,500
Non-deductible basis: $7,000 – $3,500 = $3,500 (track on Form 8606)
Full limit: $7,000 | Phaseout: $79,000 – $89,000
MAGI over lower limit: $84,000 – $79,000 = $5,000
Reduction: $7,000 × ($5,000 / $10,000) = $3,500
Deductible: $7,000 – $3,500 = $3,500
Non-deductible basis: $7,000 – $3,500 = $3,500 (track on Form 8606)

Frequently Asked Questions
What are the 2026 Traditional IRA deduction phaseout ranges?
For 2026, if you (or your spouse) are covered by a workplace retirement plan: Single/Head of Household $79,000–$89,000; Married Filing Jointly (both covered) $126,000–$146,000; Married Filing Jointly (only spouse covered) $236,000–$246,000; Married Filing Separately (covered) $0–$10,000. If neither spouse is covered by a workplace plan, the contribution is fully deductible regardless of income.
What does "active participant" mean for the IRA deduction?
You are an active participant if you (or your employer on your behalf) made contributions to a defined contribution plan (401k, 403b, SIMPLE IRA, SEP-IRA) or if you were eligible to earn benefits under a defined benefit pension plan during the year. Even if you contributed $1 to a 401k, you are an active participant and subject to the phaseout rules.
Can I still contribute if my deduction is phased out?
Yes. Even if you cannot deduct your Traditional IRA contribution, you can still make a non-deductible contribution up to the $7,000/$8,000 limit. You must file Form 8606 to record your basis (non-deductible contributions). This basis is returned tax-free when you withdraw, and non-deductible IRAs can be converted to Roth via the backdoor Roth strategy.
How is the IRA deduction phaseout calculated?
The formula is: Deductible Amount = Full Limit × (Upper Phaseout − MAGI) / Phaseout Range, rounded to the nearest $10. If the result is between $0 and $200, the minimum deductible amount is $200. The full limit is $7,000 (or $8,000 if age 50+).
What is the difference between a deductible and non-deductible IRA contribution?
A deductible contribution reduces your taxable income today — you pay tax when you withdraw in retirement. A non-deductible contribution gives no current deduction — your basis grows tax-deferred but only the earnings are taxed at withdrawal. The contribution limit is the same for both; the difference is only in tax timing. Form 8606 tracks your non-deductible basis over time.
