Contributing to a Traditional IRA can reduce your taxes for the year, but contributing to a Roth IRA will not. The Traditional IRA deduction lowers your adjusted gross income by up to $7,500 for 2026, or $8,600 if you’re 50 or older, and someone in the 22% bracket claiming the full amount saves $1,650 in federal income tax.1Internal Revenue Service. Retirement Topics – IRA Contribution Limits Whether you get the full deduction, part of it, or none depends on your income and whether you or your spouse is covered by a retirement plan at work.
How the Traditional IRA Deduction Lowers Your Tax
The deduction is taken as an adjustment to income on Schedule 1 of Form 1040, so it works whether you itemize or take the standard deduction.2Internal Revenue Service. Individual Retirement Arrangements Every dollar of deductible contribution shrinks the income you’re taxed on by a dollar.
For the 2026 tax year, the contribution limit is $7,500 if you’re under 50 and $8,600 if you’re 50 or older. That ceiling is a combined cap across all your Traditional and Roth IRAs, not a per-account figure, and you can’t contribute more than your taxable compensation for the year.1Internal Revenue Service. Retirement Topics – IRA Contribution Limits
If neither you nor your spouse has a retirement plan at work, the full deduction is available no matter what you earn.3Internal Revenue Service. IRA Deduction Limits Workplace coverage is what brings the income limits into play.
When the Deduction Starts to Shrink
Once a workplace retirement plan is in the picture, the IRS applies income-based phase-outs measured against your Modified Adjusted Gross Income (MAGI). The 2026 thresholds break down by who has the workplace plan.
If You’re Covered by a Workplace Plan
When you personally participate in a 401(k), 403(b), pension, or similar plan, the 2026 phase-outs are:4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single or head of household: full deduction at MAGI of $81,000 or less, partial from $81,000 to $91,000, none above $91,000.
- Married filing jointly: full deduction at $129,000 or less, partial from $129,000 to $149,000, none above $149,000.
- Married filing separately: partial deduction below $10,000, none at $10,000 or above.
If Only Your Spouse Is Covered
When your spouse has workplace coverage but you don’t, the joint-filer phase-out is much higher: full deduction up to $242,000 in MAGI, partial from $242,000 to $252,000, and no deduction above $252,000.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
When Contributing Doesn’t Reduce Your Taxes
Two situations produce no current-year tax reduction from an IRA contribution.
The first is a Roth IRA. Roth contributions are made with money you’ve already been taxed on, so they don’t cut your current bill. The benefit shows up later: earnings grow tax-free, and qualified withdrawals in retirement are tax-free, provided you’re at least 59½ and the account has been open for at least five years. Roth eligibility itself phases out by income. For 2026, single filers can contribute the full amount at MAGI under $153,000, a reduced amount between $153,000 and $168,000, and nothing at $168,000 or above; for joint filers those bands are under $242,000, $242,000 to $252,000, and $252,000 or above.5Internal Revenue Service. Notice 2025-67, 2026 Amounts Relating to Retirement Plans and IRAs The same combined $7,500 (or $8,600) limit covers both types.
The second is a Traditional IRA contribution made when your income is above the deduction phase-out. You can still put the money in, but it becomes a nondeductible contribution. It creates “basis” in your IRA, meaning the amount you contributed won’t be taxed again when you eventually withdraw it. You track that basis by filing Form 8606 with your return for every year you make a nondeductible contribution.6Internal Revenue Service. About Form 8606, Nondeductible IRAs Skipping Form 8606 is a common and costly mistake; without the paper trail, you can end up paying tax on the same dollars twice.
The Saver’s Credit Can Add More on Top
Lower- and moderate-income taxpayers can claim the Retirement Savings Contributions Credit, known as the Saver’s Credit, in addition to any Traditional IRA deduction. Because it’s a credit rather than a deduction, it reduces your tax bill dollar for dollar. It applies to either Traditional or Roth IRA contributions.7Internal Revenue Service. Retirement Savings Contributions Credit (Saver’s Credit)
The credit is 50%, 20%, or 10% of up to $2,000 in contributions for single filers, or $4,000 for married couples filing jointly. Maximum credit: $1,000 single, $2,000 joint. The 2026 AGI tiers are:
- 50% credit: AGI up to $48,500 joint, $36,375 head of household, $24,250 single.
- 20% credit: $48,501–$52,500 joint, $36,376–$39,375 head of household, $24,251–$26,250 single.
- 10% credit: $52,501–$80,500 joint, $39,376–$60,375 head of household, $26,251–$40,250 single.
Above those AGI limits, the credit is zero. You must be 18 or older, not a full-time student, and not claimed as a dependent.7Internal Revenue Service. Retirement Savings Contributions Credit (Saver’s Credit) If you qualify for both, the deduction lowers your AGI first, and the credit is then calculated on the tax owed on that reduced income.
The Deadline to Claim It on This Year’s Return
You have until the tax filing deadline, typically April 15, to make an IRA contribution that counts toward the prior tax year.8Internal Revenue Service. IRA Year-End Reminders A 2026 contribution can be made any time from January 1, 2026 through April 15, 2027. Filing an extension does not extend this deadline; miss it, and the money counts toward the next year instead.
When you fund an IRA between January and April, your custodian will ask which tax year the contribution is for. Choose carefully. Applying it to the wrong year can push you over the annual limit and trigger a 6% excise tax on the excess for every year it remains in the account.9Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities
How to Actually Claim the Deduction
Your IRA custodian reports contributions to the IRS on Form 5498, which typically arrives by the end of May.10Internal Revenue Service. About Form 5498, IRA Contribution Information You don’t file it yourself, but you use its figures on your return.

Individual Retirement Arrangements File Form 8606 for any nondeductible Traditional IRA contributions or Roth conversions, so your basis is on record.6Internal Revenue Service.

State income tax is a separate question. Most states with an income tax follow the federal treatment of Traditional IRA deductions, but some limit or disallow it. If your state taxes income, check whether your contribution reduces your state taxable income too.
