Yes, IRA contributions can reduce your taxable income, but only traditional IRA contributions do so directly. A traditional IRA contribution is an above-the-line deduction that lowers your adjusted gross income for the year you contribute, up to $7,500 for 2026 ($8,600 if you’re 50 or older).1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Roth IRA contributions do not reduce taxable income because you fund them with money you have already paid tax on.
Traditional IRA: A Direct Deduction, With Conditions
When you put money into a traditional IRA, you subtract the contribution from your gross income on your federal return. It’s an above-the-line deduction, meaning it reduces your AGI before you take the standard deduction or itemize.2Office of the Law Revision Counsel. 26 U.S. Code 219 – Retirement Savings Less AGI means less of your income is taxed this year.
You aren’t erasing the tax, though. You’re deferring it. Withdrawals from a traditional IRA in retirement count as ordinary income. If your bracket in retirement is lower than the one you’re in now, the deferral saves you money on net.
How Much You Can Deduct in 2026
The 2026 contribution cap is $7,500 across all your traditional and Roth IRAs combined. Add $1,100 if you’ll be 50 or older by year-end, for a total of $8,600.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Your contribution also can’t exceed your earned income for the year. If you earned $5,000, $5,000 is your cap.2Office of the Law Revision Counsel. 26 U.S. Code 219 – Retirement Savings
Split contributions still share one cap. Put $4,000 into a traditional IRA and $3,500 into a Roth, and you’ve hit the ceiling. Only the traditional portion reduces your taxable income.
When a Workplace Retirement Plan Limits the Deduction
If neither you nor your spouse is covered by a retirement plan at work, you can deduct the full traditional IRA contribution no matter how much you earn.3Internal Revenue Service. IRA Deduction Limits Once you or your spouse has access to a 401(k), pension, or similar plan, the IRS applies income phase-outs based on modified adjusted gross income (MAGI).
For 2026:1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single or head of household, covered by a workplace plan: full deduction at MAGI of $81,000 or less; partial from $81,000 to $91,000; none above $91,000.
- Married filing jointly, contributing spouse covered: full deduction at MAGI of $129,000 or less; partial from $129,000 to $149,000; none above $149,000.
- Married filing jointly, only the other spouse covered: full deduction at MAGI of $242,000 or less; partial from $242,000 to $252,000; none above $252,000.
- Married filing separately, covered by a workplace plan: partial deduction under $10,000 MAGI; none at $10,000 or above.
Inside the phase-out band, the deduction shrinks proportionally. A single filer with workplace coverage earning $86,000 sits halfway through the $81,000 to $91,000 range and can deduct roughly half of the full contribution amount.
How MAGI Is Figured
MAGI for IRA purposes starts with your AGI and adds back the IRA deduction itself, the student loan interest deduction, the foreign earned income exclusion, and the savings bond interest exclusion.4Internal Revenue Service. Modified Adjusted Gross Income For most W-2 employees without those special items, MAGI equals AGI.
Roth IRA Contributions Don’t Lower This Year’s Tax
Roth contributions come from money you’ve already been taxed on. Your AGI is the same whether you contribute or not. The payoff is on the back end: qualified withdrawals, including all the growth, come out tax-free once the account is at least five years old and you’re 59½ or older.5Internal Revenue Service. Roth Comparison Chart
Roth eligibility also has its own income limits. For 2026, the ability to contribute directly phases out between $153,000 and $168,000 of MAGI for single filers and between $242,000 and $252,000 for married couples filing jointly; married filing separately phases out under $10,000.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
The Saver’s Credit: A Second Tax Break From Either Account
Lower- and moderate-income taxpayers who contribute to any IRA, traditional or Roth, may qualify for the Retirement Savings Contributions Credit. Unlike the traditional IRA deduction, this is a credit against tax owed, worth up to $1,000 per person or $2,000 for married couples filing jointly.6Internal Revenue Service. Retirement Savings Contributions Credit (Saver’s Credit) You must be at least 18, not a dependent on someone else’s return, and not a full-time student.
For 2026, the credit is 50%, 20%, or 10% of the first $2,000 contributed per person, depending on AGI and filing status:1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- 50% credit: AGI up to $48,500 (joint), $36,375 (head of household), or $24,250 (single).
- 20% credit: AGI of $48,501 to $52,500 (joint), $36,376 to $39,375 (head of household), or $24,251 to $26,250 (single).
- 10% credit: AGI of $52,501 to $80,500 (joint), $39,376 to $60,375 (head of household), or $26,251 to $40,250 (single).
The Saver’s Credit stacks on top of any traditional IRA deduction. A qualifying couple contributing $2,000 each at the 50% tier gets both the deduction (if the traditional IRA rules allow it) and a $2,000 credit against the tax they still owe.
If Your Income Is Too High to Deduct
Passing the phase-out doesn’t lock you out of a traditional IRA. You can still contribute; the contribution is simply nondeductible. It won’t lower this year’s taxable income, but the earnings grow tax-deferred, and only the growth portion of future withdrawals is taxed, since your basis is already after-tax.
Nondeductible contributions require Form 8606 with your return so the IRS can track your after-tax basis.7Internal Revenue Service. Instructions for Form 8606 Skipping the form when required carries a $50 penalty, and you’ll need those old 8606s decades later to prove which dollars have already been taxed. A nondeductible contribution can also be the first step of a backdoor Roth conversion, though a pro-rata rule treats all your traditional, SEP, and SIMPLE IRA balances as one pool when figuring how much of a conversion is taxable.
Claiming the Deduction on Your Return
You enter the deductible amount on Schedule 1 of Form 1040, and it flows through to reduce AGI on the main form.3Internal Revenue Service. IRA Deduction Limits If your income falls in the phase-out range, use the worksheet in the Form 1040 instructions or IRS Publication 590-A to figure the reduced deduction.
Your IRA custodian reports your contributions to you and the IRS on Form 5498, which may not arrive until May or June.8Internal Revenue Service. Form 5498, IRA Contribution Information You don’t have to wait for it to file. Verify the amounts when it shows up.
The contribution deadline is the tax filing deadline itself, not the extended one. Contributions for the 2025 tax year are due by April 15, 2026, and for the 2026 tax year by April 15, 2027.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Filing an extension on your return does not extend the time to fund the IRA.
Spousal Contributions on a Joint Return
A spouse with little or no earned income can still contribute up to the full limit based on the other spouse’s earnings, as long as the couple files jointly and the working spouse’s income covers both contributions.9Internal Revenue Service. Retirement Topics – IRA Contribution Limits A stay-at-home spouse can therefore claim their own traditional IRA deduction, subject to the same MAGI phase-out that applies to the household.
