2026 Traditional IRA deduction calculator

A contribution limit and a deduction limit answer different questions

The 2026 regular contribution limit shared by one person’s Traditional and Roth IRAs is $7,500, or $8,600 when the person is age 50 or older by year-end. Compensation can create a lower contribution ceiling. A person may still have legal contribution room even when workplace-plan coverage and modified AGI reduce the Traditional IRA deduction to zero.

This calculator therefore reports three separate boundaries: shared IRA room, the maximum total Traditional IRA amount that could be deductible under the entered facts, and the maximum additional deductible Traditional contribution. It does not estimate tax savings because actual savings depend on the return, marginal tax rates, other deductions, credits, state rules, and later IRA transactions.

Workplace coverage determines which 2026 phase-out applies

For a single filer or head of household who is covered by a workplace retirement plan, the 2026 Traditional IRA deduction phases out from $81,000 through $91,000 of modified AGI. A married person filing separately who lived apart from the spouse for the entire year is treated under the single-filer range.

For a married couple filing jointly, or a qualifying surviving spouse, the phase-out for a contributor covered by a workplace retirement plan is $129,000 through $149,000. When a married-joint contributor is not covered but the spouse is covered, the range is $242,000 through $252,000. When the applicable married-filing-separately contributor lived with the spouse during the year, the range is $0 through $10,000.

If neither the contributor nor the spouse is covered by a workplace retirement plan, the workplace-plan income phase-out does not apply. The deduction can still be limited by compensation, the shared annual IRA limit, the actual Traditional IRA contribution, and special tax-return rules. The official ranges appear in the IRS announcement of 2026 retirement limits and IRS Notice 2025-67.

Coverage is about the person, not the account being opened

A workplace retirement plan can include a qualified pension, profit-sharing, stock bonus, 401(k), 403(b), governmental 457 plan, SEP, SIMPLE, or certain other arrangements. Form W-2, box 13 can help identify coverage, but contribution timing and plan rules matter. Confirm uncertain coverage with the employer or plan administrator before using an income range.

Being covered does not automatically eliminate the deduction. It selects an income phase-out. A spouse’s workplace coverage can also matter even when this contributor is not covered, but only under the applicable married filing profile.

The phase-out uses a special modified AGI calculation

Traditional IRA modified AGI is not necessarily the adjusted gross income shown on the front of a draft return. The current IRS Publication 590-A worksheet begins with tax-return figures and applies IRA-specific additions and adjustments. Social Security benefits can create a circular calculation that requires the publication’s special worksheet.

Inside an applicable range, this calculator follows the worksheet structure: it multiplies the annual IRA dollar limit by the unused share of the phase-out range, rounds the reduced amount up to the next $10, and applies the worksheet’s $200 minimum before the upper boundary. It then applies compensation, shared contribution room, and the amount contributed. Modified AGI at or below the lower boundary receives the full income-based allowance; modified AGI at or above the upper boundary receives no deduction under that phase-out.

Traditional and Roth contributions share one person-level limit

The $7,500 or $8,600 annual amount is not a separate bucket for every IRA and is not duplicated between Traditional and Roth accounts. Add regular contributions made to every Traditional and Roth IRA owned by the same person. Employer-plan contributions do not consume this IRA contribution limit.

A spouse’s IRA belongs to that spouse and uses a separate person-level limit. The special spousal IRA rule may allow a married couple filing jointly to rely on combined compensation, but that requires household allocation facts this one-person standard calculator does not collect.

A nondeductible contribution needs tax-basis records

If an allowed Traditional IRA contribution is not deductible, it may be reported as a nondeductible contribution on Form 8606. That reporting establishes basis that can matter when money later leaves any Traditional, SEP, or SIMPLE IRA. Do not assume the account custodian will track the taxpayer’s basis or that one IRA can be viewed in isolation for distribution tax treatment.

If the entered Traditional amount already exceeds the estimated deduction ceiling, the result flags the potential nondeductible portion. That is a review prompt—not a conclusion that an excess contribution exists. A nondeductible but otherwise permitted contribution and an excess contribution are different problems.

Stop for special compensation, transactions, or corrections

Choose the special path for a spousal IRA contribution, Social Security recipient who needs the special modified-AGI worksheet, qualified reservist repayment, repayment of certain birth or adoption distributions, difficulty-of-care payments, rollover, conversion, recharacterization, return of an excess contribution, prior-year carryover, inherited IRA, or any unresolved contribution type. These items can change which amounts use the regular limit or how the tax return is prepared.

Before contributing, compare custodian records with the return preparer’s calculation and the current Form 1040, Form 8606, and Publication 590-A instructions. Test the separate 50%, 20%, or 10% retirement-contribution credit with the 2026 Saver’s Credit Calculator; a supported Traditional IRA contribution can potentially qualify for both the deduction and credit, but each uses different income and adjustment rules. For the related eligibility question, use the 2026 Roth IRA contribution limit calculator; for workplace deferrals, use the 2026 401(k) contribution limit calculator; and for a separate health-savings opportunity, use the 2026 HSA contribution limit calculator.

This calculator provides general educational arithmetic for one standard 2026 Traditional IRA deduction scenario. It is not tax, legal, accounting, retirement-plan, investment, or financial advice. Filing facts, workplace coverage, IRA-eligible compensation, modified AGI, Social Security taxation, spousal compensation, special payments, contribution timing, corrections, and tax reporting can change the result.
