About this calculator
Traditional IRA contributions may be tax-deductible, reducing your adjusted gross income dollar-for-dollar — but only if your Modified Adjusted Gross Income (MAGI) and workplace plan coverage fall within IRS limits. The 2023 contribution limit is $6,500 per year ($7,500 if age 50 or older). If you are covered by an employer plan, deductibility phases out for single filers with MAGI between $73,000–$83,000 and for married-filing-jointly filers between $116,000–$136,000. Married taxpayers who file separately and are covered by a plan face a much narrower phase-out of $0 to $10,000 — a range Congress fixed in statute and never indexes for inflation, so it is the same for every tax year — which means any meaningful income eliminates the deduction entirely; this calculator therefore shows $0 for a covered separate filer with MAGI above $0. The full deduction formula is: Deduction = contributionLimit × 1 if under the threshold, or 0 if over (simplified). Your actual tax savings equal the deductible amount multiplied by your marginal tax rate. Non-deductible contributions still grow tax-deferred, but withdrawals of principal are not taxed again at retirement.
How to use
Suppose you are 52 years old, have a MAGI of $60,000, file as single, and are not covered by an employer plan. Your contribution limit = $7,500 (age 50+ catch-up). Since you have no employer plan, the full contribution is deductible regardless of income. Deductible amount = $7,500 × 1 = $7,500, which grows tax-deferred until retirement (multiply by your marginal rate to estimate the tax saving).
Frequently asked questions
How does being covered by an employer retirement plan affect my IRA deduction?
If you or your spouse participates in a workplace plan such as a 401(k) or 403(b), the IRS phases out the traditional IRA deduction at certain income levels. For single filers covered by a plan in 2023, the deduction starts phasing out at $73,000 MAGI and disappears entirely above $83,000. For married filing jointly, the phase-out runs from $116,000 to $136,000. If neither you nor your spouse is covered by a workplace plan, there is no income limit on deductibility.
What is the IRA catch-up contribution and who qualifies for it?
Taxpayers aged 50 or older are allowed to contribute an additional $1,000 per year above the standard IRA limit, known as the catch-up contribution. For 2023, this brings the total allowable contribution to $7,500 instead of $6,500. The catch-up provision exists to help older workers accelerate retirement savings in the years closest to retirement. You must actually be 50 by December 31 of the tax year to qualify for the higher limit.
What happens if I make a non-deductible IRA contribution?
If your income exceeds the deduction phase-out range, you can still contribute to a traditional IRA, but the contribution will be non-deductible. You should file IRS Form 8606 to track these after-tax contributions so you are not taxed again on the principal when you withdraw. The investment growth inside the account remains tax-deferred until withdrawal. Many high earners use non-deductible IRA contributions as the first step in a 'backdoor Roth IRA' conversion strategy to gain tax-free growth.
Why does married filing separately have such a low IRA deduction limit?
If you are married, file a separate return, and are covered by a workplace retirement plan (or lived with a spouse who is covered) at any time during the year, the IRS phases out your traditional IRA deduction between $0 and $10,000 of Modified AGI. Unlike the single and joint thresholds, this $0–$10,000 range is written into the tax code and is not adjusted for inflation, so it is identical every year — the IRS confirms it 'remains between $0 and $10,000' for 2025 and 2026. In practice this means a covered separate filer with essentially any income gets little or no deduction. The one exception: if you file separately and did NOT live with your spouse at any point during the year, the IRS treats you as single for this test, so the higher single phase-out applies instead.
