Open the Traditional IRA Deduction Calculator →A traditional IRA contribution is deductible on your federal return, but how much you can deduct depends on workplace plan coverage. If neither you nor your spouse is covered by an employer plan, the full contribution (up to $7,500 for 2026, or $8,600 at age 50+) is deductible regardless of income. If you are covered, the deduction phases out under IRC §219(g): $81,000 to $91,000 of MAGI for single filers and $129,000 to $149,000 for married filing jointly in 2026. Any contribution you cannot deduct is a nondeductible contribution reported on Form 8606.
- The contribution is always allowed if you have compensation; only the deduction is income-limited.
- No plan coverage = full deduction at any income (IRC §219).
- 2026 limits: $7,500 base, $8,600 at 50+ (the $1,100 catch-up is now COLA-indexed). 2025: $7,000 / $8,000.
- 2026 covered phase-out: Single/HOH $81,000-$91,000; MFJ $129,000-$149,000; MFS $0-$10,000.
- Non-covered spouse of a covered worker: $242,000-$252,000 (2026), a much higher range.
- Nondeductible contributions go on Form 8606 to create basis and avoid double taxation.
- No upper age limit since the SECURE Act of 2019; you just need taxable compensation.
- Above-the-line: the deduction lowers AGI directly, even if you take the standard deduction.
- Deadline: the unextended return due date (April 15, 2026 for tax year 2025).
- Covered and over the limit? A Roth IRA or backdoor Roth usually beats a nondeductible traditional contribution.
What the Traditional IRA Deduction Is
A traditional IRA lets you set aside money for retirement and, in many cases, deduct the contribution from your taxable income in the year you make it. The account then grows tax-deferred, and you pay ordinary income tax on withdrawals in retirement. The deduction is the up-front tax benefit, and it is the part of the traditional IRA that most often confuses people, because whether you can take it depends on your income and on whether you are covered by a workplace retirement plan.
The governing statute is IRC §219, which allows the deduction, and IRC §219(g), which limits it for people who are active participants in an employer plan. The detailed mechanics live in IRS Publication 590-A. The crucial distinction to understand from the start is between contributing and deducting. Anyone with taxable compensation can contribute to a traditional IRA; the income rules only decide how much of that contribution you get to deduct.
Why the Deduction Matters
The deduction is above-the-line, meaning it reduces your adjusted gross income directly under IRC §62(a)(7). That makes it valuable even if you take the standard deduction, and lowering AGI can ripple into other benefits - a larger Saver's Credit, education credits, a lower threshold for the net investment income tax, and reduced Medicare premiums. A deductible $7,500 contribution at a 24 percent marginal rate is worth $1,800 in federal tax saved this year.
Contribution Limits and Deadlines (2026 and 2025)
The annual IRA contribution limit is the same dollar figure for traditional and Roth IRAs combined, and it is the ceiling on your deduction. For 2026 the base limit is $7,500, up from $7,000 in 2025. The age-50 catch-up is $1,100 for 2026 (up from $1,000), because the SECURE 2.0 Act made the catch-up subject to a cost-of-living adjustment for the first time. So the total at age 50 and over is $8,600 for 2026 and $8,000 for 2025.
| Limit | 2026 | 2025 |
|---|---|---|
| Base contribution (under 50) | $7,500 | $7,000 |
| Age-50 catch-up | $1,100 | $1,000 |
| Total at age 50 and over | $8,600 | $8,000 |
Two limits cap your contribution: the dollar figure above, and your taxable compensation. You cannot contribute more than you earned. Compensation means wages, salary, self-employment net earnings, and certain other earned income; it does not include investment income, Social Security, or pension distributions. The deadline to make a contribution for a tax year is the unextended due date of that year's return - April 15, 2026 for the 2025 tax year, and April 15, 2027 for 2026. Filing an extension does not push the IRA deadline.
No More Age Cap
Before 2020 you could not contribute to a traditional IRA after age 70 and a half. The SECURE Act of 2019 repealed that cap, so you can now contribute and deduct at any age, as long as you have compensation. One caveat: deductible IRA contributions made after 70 and a half reduce the amount of a qualified charitable distribution you can later exclude from income, under an anti-abuse rule that pairs the two provisions.
The Active-Participant Rule
The single fact that decides whether your deduction is income-limited is whether you are an "active participant" in an employer-sponsored retirement plan, defined in IRC §219(g)(5). If you are not an active participant - and neither is your spouse - the full contribution is deductible no matter how high your income. The phase-out only exists for people with workplace plan coverage.
You are an active participant if you are covered by any of these for any part of the year:
- A 401(k) or 403(b) where you or your employer contributed during the year.
- A SEP-IRA or SIMPLE IRA that received a contribution for you.
- A defined benefit pension where you are merely eligible to participate, even if you contribute nothing.
- Certain government and union plans.
The easiest way to check is box 13 on your Form W-2: the "Retirement plan" box is checked when your employer treats you as an active participant. Two traps catch people. First, being covered for even one day makes you an active participant for the entire year, so a new job with automatic 401(k) enrollment can retroactively trigger the phase-out. Second, for a pension, mere eligibility counts - you do not have to put anything in to be "covered."
The MAGI Phase-Out Ranges
When coverage applies, IRC §219(g) phases out the deduction over a modified AGI range that depends on your filing status and on which spouse is covered. Inside the range the deduction shrinks; above it, the deduction is zero. The ranges are adjusted for inflation each year (except the married-filing-separately range, which is fixed by statute at $0 to $10,000).
| Situation | 2026 | 2025 |
|---|---|---|
| Single / Head of Household, you covered | $81,000 - $91,000 | $79,000 - $89,000 |
| Married Filing Jointly, you covered | $129,000 - $149,000 | $126,000 - $146,000 |
| Married Filing Jointly, only spouse covered | $242,000 - $252,000 | $236,000 - $246,000 |
| Married Filing Separately, covered | $0 - $10,000 | $0 - $10,000 |
| Neither spouse covered | No income limit | No income limit |
The most generous treatment is for a person who is not covered but is married to someone who is: that household uses the high $242,000 to $252,000 range for 2026, so a non-working or non-covered spouse can usually deduct a full IRA at incomes that would eliminate the covered spouse's deduction. The harshest is married filing separately while covered, where the deduction begins phasing out at the very first dollar of MAGI.
What Counts as Modified AGI
Modified AGI for this purpose (IRC §219(g)(3)) is your AGI computed without the traditional IRA deduction itself, then with several items added back: the student loan interest deduction, the foreign earned income and housing exclusions and deductions, the excluded savings bond interest, and excluded employer adoption assistance. For most people without those specific items, MAGI is the same as AGI. The precise computation is in Publication 590-A Worksheet 1-1. Our MAGI guide walks through the seven different MAGI definitions in the tax code.
How the Deduction Is Calculated
If your MAGI is below the bottom of your range, you deduct the full contribution. If it is at or above the top, the deduction is zero. Inside the range, IRS Publication 590-A Worksheet 1-2 reduces the deduction in proportion to how far you are into the range.
- Step 1 - Distance from the top. Subtract your MAGI from the upper end of your phase-out range.
- Step 2 - Divide by the width. Divide that distance by the range width: $10,000 for single, head of household, and the spousal range; $20,000 for married filing jointly when you are the covered spouse.
- Step 3 - Multiply by the limit. Multiply by your contribution limit ($7,500, or $8,600 at 50+).
- Step 4 - Round and floor. Round the result up to the next $10. If it is more than zero but under $200, you may still deduct $200.
For example, a single filer covered by a 401(k) with $86,000 of MAGI in 2026 is $5,000 below the $91,000 top of the $81,000 to $91,000 range. That is 50 percent of the $10,000 width, so the deductible limit is 50 percent of $7,500, or $3,750. If they contribute the full $7,500, then $3,750 is deductible and the other $3,750 is nondeductible. The Traditional IRA Deduction Calculator runs this worksheet for any income, coverage, and filing status.
Deductible vs Nondeductible Contributions and Form 8606
When the phase-out reduces or eliminates your deduction, the part you cannot deduct does not have to be wasted. You can leave it in the IRA as a nondeductible contribution. The key compliance step is filing Form 8606 for the year you make a nondeductible contribution. Form 8606 records your "basis" - the running total of after-tax dollars you have put into your traditional IRAs.
Basis matters because of the pro-rata rule in IRC §408(d). When you later take a distribution or do a Roth conversion, a proportional slice comes out tax-free as a return of that basis. Without a filed Form 8606, the IRS has no record of the after-tax money, and you risk paying income tax a second time on dollars you already paid tax on. Form 8606 is also where the basis lives for the backdoor Roth strategy.
The $50 Penalty Trap
Failing to file Form 8606 when required carries a $50 penalty, and overstating basis carries a $100 penalty, but the real cost is the lost basis. Practitioners routinely see clients who made nondeductible contributions for years without filing the form and then cannot prove their basis at withdrawal. Keep every Form 8606 permanently; it is one of the few tax records you should never discard.
The Spousal IRA Rule
A spouse with little or no earned income can still fund an IRA through the Kay Bailey Hutchison Spousal IRA rule in IRC §219(c). On a joint return, the working spouse's compensation can support a contribution to the other spouse's IRA, up to the full limit for each spouse. The only ceiling is that the couple's combined contributions cannot exceed their joint taxable compensation.
Deductibility is then tested separately for each spouse under §219(g), based on each one's own coverage status. This is where the two different phase-out ranges come into play. Consider a household where one spouse has a 401(k) and earns $180,000, and the other spouse has no job and no plan:
- The covered spouse uses the $129,000 to $149,000 range for 2026. At $180,000 of joint MAGI, that spouse's deduction is fully phased out - any contribution is nondeductible.
- The non-covered spouse uses the higher $242,000 to $252,000 range. At $180,000 of MAGI, that is below the bottom of the range, so the non-covered spouse can deduct a full $7,500 (or $8,600 at 50+).
That asymmetry is a planning gift: a one-earner household can frequently capture a full deduction on the non-working spouse's IRA even when the earner is shut out.
Traditional vs Roth and the Backdoor Roth
The traditional and Roth IRAs share one contribution limit but reverse the timing of the tax break. A deductible traditional contribution saves tax now and is taxed on withdrawal; a Roth contribution saves nothing now but is tax-free later and skips lifetime required minimum distributions. The classic rule of thumb: traditional wins if you expect a lower tax rate in retirement, Roth wins if you expect the same or a higher rate.
The decision changes when you are covered by a workplace plan and earn too much to deduct. In that case the traditional contribution is nondeductible - you get no up-front break and the growth is still taxed on withdrawal. A Roth contribution, by contrast, gives tax-free growth. So for a covered high earner, the better question is usually "can I do a Roth?" rather than "can I deduct a traditional?"
The Backdoor Roth
If your income is also above the Roth contribution limit, the backdoor Roth strategy combines both ideas: make a nondeductible traditional IRA contribution (no income limit applies to contributing), then convert it to a Roth. Because the contribution was after-tax, the conversion is largely tax-free - unless you hold other pre-tax IRA money, in which case the pro-rata rule of IRC §408(d) taxes part of the conversion. Read our Roth Conversion Tax Guide and model the cost in the Roth IRA Contribution Calculator before executing.
Withdrawals, RMDs, and State Tax
Deductible contributions and their earnings are fully taxable as ordinary income when withdrawn. Withdrawals before age 59 and a half generally add a 10 percent early-distribution penalty under IRC §72(t), with exceptions for first-home purchase (up to $10,000), higher education, certain medical costs, and others. Any nondeductible basis tracked on Form 8606 comes out tax-free pro-rata.
Traditional IRAs are subject to required minimum distributions (RMDs) starting at age 73 (rising to 75 in 2033 under SECURE 2.0), because the government eventually wants its deferred tax. This is a major contrast with the Roth IRA, which has no lifetime RMDs. Our RMD guide covers the calculation and the timing.
State Treatment
Most states follow the federal IRA deduction, but not all. Pennsylvania, for instance, does not allow a state deduction for traditional IRA contributions, and several states have their own quirks for IRA income in retirement. The federal deduction estimated by the calculator does not model state tax, so check your state's rules separately. The federal tax saved is generally the larger and more uniform benefit.

The mistake we correct most often is a covered client deducting an IRA they were not entitled to deduct. Someone with a 401(k) and $130,000 of single-filer MAGI assumes the contribution is deductible because "I put money in an IRA." It is not - box 13 makes them an active participant well above the $91,000 ceiling, and the deduction is zero. We file Form 8606 to record the basis and amend the return if the deduction was already claimed.
For most of these covered high earners, we skip the deductible-traditional question entirely and recommend a backdoor Roth. The contribution is nondeductible either way, so converting it to Roth captures tax-free growth at no additional tax cost. The one thing we always check first is whether the client holds a pre-tax rollover IRA, because the pro-rata rule would tax the conversion. If they do, we look at rolling that balance into a current 401(k) to clear the way.
The spousal range is the planning win people miss. In a one-earner household where the earner has a 401(k), the non-working spouse can frequently deduct a full IRA because the non-covered-spouse phase-out does not start until $242,000 for 2026. We make sure both spouses' IRAs are funded in these households, not just the earner's.
Finally, we treat Form 8606 as a permanent record. Clients who made nondeductible contributions for a decade and never filed the form cannot prove their basis at withdrawal, and the IRS defaults to taxing it all. We reconstruct the basis from custodian statements where we can, but it is far cheaper to file the form every year a nondeductible contribution is made.
Real-World Scenarios
When the General Rules Do Not Apply
- Not enough compensation. You cannot contribute more than your taxable earned income. A retiree living on Social Security and pension income has no contributable compensation, even with a deductible-looking income.
- Both spouses covered. When both spouses are active participants and file jointly, each uses the lower $129,000-$149,000 range (2026); the higher spousal range never applies.
- Mid-year coverage. Coverage for even one day makes you an active participant for the whole year. A new job's automatic enrollment can retroactively trigger the phase-out.
- Pension eligibility. For a defined benefit pension, you are covered if you are eligible, even with zero contributions - a common surprise for long-tenured employees.
- Excess contributions. Contributing over the limit or over your compensation triggers a 6 percent excise tax under IRC §4973 each year until corrected.
- State nonconformity. A few states (such as Pennsylvania) do not allow the IRA deduction for state tax; the calculator estimates federal tax only.
- QCD offset after 70½. Deductible IRA contributions made after age 70 and a half reduce the amount you can later exclude as a qualified charitable distribution.
- Inherited IRAs. You cannot contribute to an inherited IRA; the deduction rules here apply only to your own traditional IRA.
