Find out how much of your Traditional IRA contribution is deductible in 2026, what tax savings that unlocks, and how your balance could grow โ whether or not you have a workplace plan.
This IRA calculator is built around the 2026 IRS rules for Traditional IRAs โ not Roth IRAs (those have their own contribution and income structure). Enter your gross income, filing status, and whether you or your spouse participate in an employer-sponsored plan. The tool checks your figures against the IRS deduction phase-out ranges โ single filers covered by a workplace plan phase out between $81,000 and $91,000; married filing jointly with the contributing spouse covered phase out between $129,000 and $149,000. You'll get a deductible amount, an estimated federal tax savings, and a 10-, 20-, and 30-year projection of your IRA balance at a 7% average annual return. Everything stays on your device โ nothing is stored or transmitted.
1. Select your tax filing status (Single, Married Filing Jointly, Married Filing Separately, Head of Household).
2. Enter your modified adjusted gross income (MAGI) for 2026.
3. Indicate whether you are covered by a workplace retirement plan (401(k), 403(b), pension, etc.).
4. If married, indicate whether your spouse is covered by a workplace plan even if you are not.
5. Enter your age โ this determines whether your contribution limit is $7,500 (under 50) or $8,600 (50+).
6. Click Calculate to see your maximum deductible contribution, estimated tax savings, and long-term growth projection.
The calculator applies a two-step formula. First, it determines your allowable contribution: the lesser of your earned income or the annual limit ($7,500 / $8,600). Second, it calculates your deductible portion using the IRS phase-out formula:
Deductible amount = Contribution limit ร (1 โ [(MAGI โ Phase-out floor) รท Phase-out range])
If your MAGI falls below the phase-out floor, 100% is deductible. If it exceeds the ceiling, no deduction applies but a non-deductible contribution may still be made. The tax savings estimate then multiplies the deductible amount by your marginal federal rate from the 2026 brackets.
Three numbers matter most from this calculator: your deductible amount (the actual current-year tax benefit), your non-deductible contribution room (still valuable โ it grows tax-deferred), and your projected balance (a 30-year horizon at 7% shows how even $7,500 per year compounds meaningfully). If your deduction phases out entirely, the calculator flags whether a Roth IRA or backdoor Roth conversion deserves consideration instead.
The deduction phase-out only applies when you (or your spouse) are an "active participant" in an employer-sponsored retirement plan during the year. Being eligible to participate isn't enough โ you actually have to be covered. If neither you nor your spouse has access to a workplace plan, your traditional IRA contribution is fully deductible at any income level.
For 2026, the phase-out ranges are (IRS):
A nuance many filers miss: if you contribute to a 401(k) but then leave your employer mid-year, you were still an "active participant" for that tax year, and the phase-out applies even if you don't contribute for the second half of the year. Self-employed individuals who set up a SEP-IRA or SIMPLE IRA are also active participants.
Once your income exceeds the phase-out ceiling, you lose the upfront deduction โ but you don't lose access to the account. A non-deductible traditional IRA still grows tax-deferred, meaning no annual taxes on dividends or capital gains inside the account. You'll owe ordinary income tax only on the earnings when you withdraw, not on the after-tax principal (tracked via IRS Form 8606).
This matters because high earners who can't do a direct Roth IRA (2026 phase-out: single $153,000โ$168,000; MFJ $242,000โ$252,000) often use a non-deductible traditional IRA as the first step in a backdoor Roth conversion. If you have no other pre-tax IRA balances, this strategy lets you move after-tax money into a Roth without any pro-rata tax complications.
The key takeaway: the deduction is the bonus, not the whole point. Even without it, a traditional IRA provides a tax-advantaged growth vehicle that taxable brokerage accounts can't match.
The 2026 IRA contribution deadline is April 15, 2027 โ but waiting until the deadline can cost you real money. A $7,500 contribution made on January 1, 2026, earns roughly one extra year of compounding over the same contribution made in April 2027. At a 7% return over 30 years, that single year difference adds about $1,460 to the ending balance.
Spousal IRAs deserve attention too. A non-working spouse can contribute up to $7,500 (or $8,600 if 50+) to their own traditional IRA, as long as the household has enough earned income to cover both contributions. A couple where only one spouse works can shelter up to $17,200 combined โ or $16,100 in a 10% bracket year after the standard deduction of $32,200 (IRS) โ purely through IRA contributions.
Several variables shape your IRA outcome beyond the base contribution limit. Your MAGI โ which adds back items like student loan interest and rental losses to adjusted gross income โ determines whether the deduction phases out. Your age gates the catch-up contribution: the standard limit is $7,500, and turning 50 by December 31, 2026, unlocks the extra $1,100 for a total of $8,600 (IRS). Your marginal tax rate determines the immediate dollar value of any deduction โ a $7,500 deduction saves $1,650 in the 22% bracket but $2,700 in the 36% bracket. Investment choices inside the IRA drive long-run growth; index funds with low expense ratios typically outperform actively managed alternatives over 20-plus-year horizons. Finally, your withdrawal timeline affects whether traditional or Roth makes more sense; those expecting higher income in retirement often do better with Roth now.
David's MAGI of $74,000 falls below the $81,000 phase-out floor. His full $7,500 contribution is deductible. At a 22% marginal rate, he saves $1,650 in federal taxes this year. Invested at 7% annually, that $7,500 grows to roughly $57,000 in 30 years.
Sandra is the contributing spouse and she's covered by a workplace plan. Their MAGI of $138,000 sits inside the $129,000โ$149,000 MFJ phase-out range. The calculator works out the phase-out: ($138,000 โ $129,000) รท $20,000 = 45% phased out. Sandra can deduct 55% of $8,600, or about $4,730. Tom, who has no workplace plan and is in a separate account, checks the spouse-not-covered phase-out: $138,000 is well below $242,000, so his full $8,600 is deductible. Together they bank roughly $13,330 in deductible contributions for 2026.
1. Contribute to your IRA before funding a taxable account. The tax-deferred (or tax-free for Roth) growth is nearly impossible to replicate outside a retirement account.
2. Calculate MAGI before December 31 to decide whether to make a deductible or non-deductible contribution โ or whether to pivot to a Roth instead.
3. Track non-deductible contributions with Form 8606 every year you make them. Missing this creates a double-taxation problem decades later at withdrawal.
4. Don't over-contribute. Excess contributions carry a 6% annual excise tax until corrected. The calculator flags any overage.
5. Pair the IRA with 401(k) contributions. Max the employer match first (free money), then fund the IRA, then go back and max the 401(k).
6. Consider a SEP-IRA if self-employed. The 2026 SEP-IRA limit is $72,000 โ orders of magnitude larger than the traditional IRA ceiling.
A: The 2026 IRA contribution limit is $7,500 for individuals under age 50, and $8,600 for those 50 and older (the $1,100 catch-up contribution). This limit is shared across all traditional and Roth IRAs you own โ you can't contribute $7,500 to each (IRS).
A: Yes โ having a 401(k) doesn't prevent you from contributing to a traditional IRA. It only affects whether your traditional IRA contribution is deductible. If your income falls inside or above the phase-out range, your contribution may be only partially or not at all deductible (IRS).
A: If the contributing spouse is covered by a workplace plan, the deduction phases out between $129,000 and $149,000 MAGI. If only the other spouse is covered, the range is $242,000โ$252,000 โ much more generous (IRS).
A: Excess contributions are subject to a 6% excise tax for each year the excess remains in the account. You can avoid the penalty by withdrawing the excess plus any net income attributable before your tax filing deadline (including extensions).
A: Often yes โ especially if your MAGI exceeds Roth IRA limits too. A non-deductible IRA still grows tax-deferred, and it can be converted to a Roth (the "backdoor Roth" strategy) if you have no other pre-tax IRA balances.
A: A traditional IRA offers a potential upfront tax deduction (taxed at withdrawal); a Roth IRA offers no upfront deduction but tax-free qualified withdrawals. Which is better depends on whether your tax rate is higher now or in retirement.
A: You can contribute to your 2026 IRA any time between January 1, 2026, and the tax filing deadline of April 15, 2027.
A: Yes โ a spousal IRA lets a non-working spouse contribute up to $7,500 (or $8,600 if 50+) as long as the couple files jointly and the working spouse has at least enough earned income to cover both contributions.
