Traditional IRA Deduction Calculator

The calculator starts with the 2026 IRA contribution limit of $7,500, plus the $1,100 age 50 catch-up amount when applicable. It then compares that annual limit with taxable compensation and subtracts other IRA or Roth IRA contributions already made for the same person.

Next, it selects the 2026 traditional IRA deduction phase-out range based on workplace retirement plan coverage. Covered single and head-of-household filers use the $81,000 to $91,000 range. Covered joint and qualifying surviving spouse filers use the $129,000 to $149,000 range. A contributor who is not covered but has a covered spouse on a joint return uses the $242,000 to $252,000 range.

Inside a phase-out range, the calculator follows the IRS worksheet concept by reducing the annual deduction limit proportionally, rounding the reduced amount up to the next $10, and applying the small-deduction minimum when the worksheet still allows a deduction. It then splits the entered traditional IRA contribution into deductible, nondeductible, and possible excess amounts.

A traditional IRA contribution and a traditional IRA deduction are different tests

The first question is whether the contribution itself fits inside the IRA limit and taxable compensation limit. The second question is whether the contribution is deductible on the return. High income does not automatically prevent a traditional IRA contribution, but it can turn the contribution into a nondeductible IRA amount that needs careful basis tracking.

2026 traditional IRA deduction phase-out ranges

The phase-out applies only when the taxpayer or spouse is covered by a workplace retirement plan. The 2026 ranges below come from IRS Publication 590-A update language and IRS Notice 2025-67. Married filing separately is harsh when spouses lived together, so the calculator treats that as a separate filing-status choice.

Workplace plan coverage is usually a W-2 and plan-record question

The deduction table changes when the contributor is an active participant in an employer retirement plan. For employees, Form W-2 box 13 often indicates retirement plan coverage. For business owners and self-employed taxpayers, SEP, SIMPLE, qualified plan, and similar coverage facts can matter. A contribution to a workplace plan is not always required for coverage to affect the IRA deduction table.

Nondeductible IRA basis needs Form 8606 discipline

If the calculator shows a nondeductible traditional IRA contribution, keep the custodian confirmation and prepare Form 8606 support. That basis can affect later IRA distributions and Roth conversions. For backdoor Roth planning, coordinate this result with all traditional, SEP, and SIMPLE IRA balances because pro-rata rules can change the tax cost of a conversion.

Coordinate IRA deductibility with Roth eligibility and credits

If the deduction is reduced or lost, compare the result with the Roth IRA Eligibility Calculator before choosing a contribution path. If the taxpayer has lower income, run the Saver's Credit Calculator because an IRA contribution can also interact with the retirement savings contributions credit. For whole-return modeling, use the Taxable Income Calculator.
