Traditional IRA Calculator: Maximize Your Tax Deduction

How a Traditional IRA Works

A traditional IRA (Individual Retirement Account) lets you contribute pre-tax or after-tax dollars, depending on your income and whether you have a workplace retirement plan. Your investments grow tax-deferred, meaning you pay no taxes on dividends, interest, or capital gains while the money stays in the account. When you withdraw in retirement, you pay ordinary income tax on the distributions.

For 2026, the contribution limit is $7,000 per year, or $8,000 if you are 50 or older. You can contribute to a traditional IRA even if you also have a 401(k), though the deductibility depends on your income and filing status.

Traditional IRA Deductibility Rules for 2026

Whether your traditional IRA contribution is tax-deductible depends on two factors: whether you (or your spouse) are covered by a workplace retirement plan, and your income.

Not covered by a workplace plan: Your full contribution is deductible regardless of income. This applies to self-employed individuals who have no SEP-IRA or SIMPLE IRA, and to employees whose employer does not offer a retirement plan.

Covered by a workplace plan, single: Full deduction if MAGI is under approximately $79,000. Partial deduction between $79,000 and $89,000. No deduction above $89,000.

Covered by a workplace plan, married filing jointly: Full deduction under approximately $126,000. Partial between $126,000 and $146,000. No deduction above $146,000.

Not covered but spouse is: Full deduction under approximately $236,000. Partial between $236,000 and $246,000. No deduction above $246,000.

Even if you cannot deduct your contribution, a non-deductible traditional IRA still provides tax-deferred growth, and can be converted to a Roth IRA later (the backdoor Roth strategy).

The Real Value of a Traditional IRA Deduction

A fully deductible $7,000 IRA contribution reduces your federal taxable income by $7,000. The actual tax savings depend on your marginal bracket:

12% bracket: $7,000 contribution saves $840 in federal taxes.

22% bracket: $7,000 contribution saves $1,540 in federal taxes.

24% bracket: $7,000 contribution saves $1,680 in federal taxes.

32% bracket: $7,000 contribution saves $2,240 in federal taxes.

Add state income tax savings on top of these federal numbers. In a high-tax state like California or New York, a 22% federal bracket taxpayer might save an additional $700 to $900 in state taxes, making the true effective cost of a $7,000 contribution as low as $4,760.

Required Minimum Distributions: What You Need to Know

Traditional IRAs require you to begin taking Required Minimum Distributions (RMDs) starting at age 73 (per the SECURE 2.0 Act). The RMD amount is calculated by dividing your account balance by an IRS life expectancy factor. Failing to take your RMD results in a 25% excise tax on the amount you should have withdrawn.

RMD planning is a critical part of retirement tax strategy. Large traditional IRA balances can push retirees into higher tax brackets, increase Medicare IRMAA surcharges, and make more of their Social Security benefit taxable. Strategies to manage RMDs include Roth conversions in lower-income years before age 73, qualified charitable distributions (QCDs) for those who are charitably inclined, and strategic withdrawal planning in the decade before RMDs begin.

Traditional IRA vs. 401(k): Key Differences

Investment flexibility: IRAs held at brokerages like Fidelity, Vanguard, or Schwab typically offer thousands of investment options. Most 401(k) plans offer a limited menu of 15 to 30 funds.

Contribution limits: 401(k) limits are much higher at $23,500 vs. $7,000 for an IRA. For high earners who want to defer more income, the 401(k) is essential.

Fees: IRAs at large brokerages can have near-zero costs. Some 401(k) plans have high administrative and fund expenses that erode returns.

The typical recommendation is to contribute to the 401(k) enough to capture the employer match, then fund the IRA to the limit, and then return to the 401(k) for any additional retirement saving.

Frequently Asked Questions About Traditional IRAs

Can I contribute to a traditional IRA at any age?

Yes. As of the SECURE Act, there is no age limit for traditional IRA contributions as long as you have earned income. Previously, contributions were prohibited after age 70.5. Now workers of any age can contribute if they have qualifying earned income.

What counts as earned income for IRA purposes?

Earned income includes wages, salaries, tips, self-employment income, and alimony received under pre-2019 divorce agreements. It does not include investment income, Social Security benefits, pension distributions, or rental income.

What if I contribute more than the limit?

Excess contributions are subject to a 6% excise tax each year the excess remains in the account. To avoid this penalty, you must withdraw the excess contribution plus any earnings on it before your tax filing deadline, including extensions.
