What is a Traditional IRA?
A Traditional IRA is a US Individual Retirement Account that you open and own outside any employer plan. Contributions may be tax-deductible against current income depending on workplace plan coverage and MAGI, investments grow tax-deferred, withdrawals after age 59 1/2 are taxed as ordinary income, and Required Minimum Distributions begin at age 73. The 2026 contribution limit is $7,000, plus a $1,000 catch-up at age 50 and older.
Detailed definition
The Traditional Individual Retirement Account was created by the Employee Retirement Income Security Act (ERISA) of 1974 as a workplace-plan substitute for the roughly half of US workers who had no employer pension. Senator Jacob Javits authored the IRA provisions in ERISA Title II, and the IRS issued the first Form 5498 contribution-reporting rules in 1975. Universal IRA eligibility (anyone with earned income, employer plan or not) arrived via the Economic Recovery Tax Act of 1981 and survived in modified form through every major tax law since.
An IRA is a tax wrapper, not an investment. You open the account at a custodian (Fidelity, Vanguard, Schwab, Wealthfront, and so on charge zero account fees on basic IRAs) and choose what to hold inside: index funds, individual stocks, bonds, CDs, ETFs, and at most custodians a brokerage option for options or other instruments. The wrapper provides tax-deferred growth, while contribution deductibility depends on whether you also have access to a workplace retirement plan and how high your Modified Adjusted Gross Income (MAGI) is.
Once retirement starts, the Traditional IRA operates on the deferred-tax bet: you took the deduction at your peak earning marginal rate and you pay tax now at your retirement marginal rate, which for most US retirees is lower because earned income has stopped. The RMD machinery enforces that the IRS eventually collects on those deferred taxes. Modern planning increasingly uses partial Roth conversions in the low-income years between retirement and the start of Social Security or RMDs to smooth lifetime tax exposure.
2026 deduction phase-outs
If covered by a workplace plan: Single / HoH $79,000 to $89,000 MAGI phase-out MFJ both covered $126,000 to $146,000 MAGI phase-out MFJ spouse covered $236,000 to $246,000 MAGI phase-out MFS $0 to $10,000 MAGI phase-out If not covered by a workplace plan: Full $7,000 deduction at any income (plus $1,000 catch-up at 50+)
- MAGI for IRA purposes: AGI plus student loan interest deduction, foreign earned income exclusion, and a few smaller add-backs.
- Active participant: anyone covered by a 401(k), 403(b), 457(b), SEP, SIMPLE, or defined-benefit pension where the employer or employee made a contribution or accrued a benefit in the year.
- Inside the phase-out range: deductible amount = $7,000 x (top of range minus MAGI) / range width, rounded to nearest $10.
- Above the range: zero deduction, but non-deductible contributions are still permitted up to $7,000 (file Form 8606 to track basis).
Worked example
Take a 45-year-old single filer earning $75,000 in 2026 who is an active 401(k) participant. She wants to know whether a $7,000 Traditional IRA contribution will be fully deductible.
- MAGI: $75,000 W-2 income, minus $4,000 of student-loan interest (added back for IRA MAGI), giving $75,000 + $4,000 = $79,000... right at the bottom of the phase-out floor.
- Phase-out window: $79,000 to $89,000 = $10,000 wide.
- Distance into the window: MAGI $79,000 minus floor $79,000 = $0 above the floor (full deduction available).
- Deductible amount: $7,000 (the full contribution).
- Tax saving: at her 22 percent federal marginal bracket, $7,000 x 22 percent = $1,540 less federal tax in 2026.
Traditional IRA vs Roth IRA
The Traditional and Roth IRA share the $7,000 combined contribution cap but invert the tax timing.
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| 2026 contribution limit | $7,000 combined ($8,000 at 50+) | |
| Contribution deductibility | Yes, subject to phase-outs | No |
| Income limit to contribute | None | Phase-out $150,000 to $165,000 single, $236,000 to $246,000 MFJ in 2026 |
| Growth | Tax-deferred | Tax-free |
| Qualified withdrawal tax | Ordinary income | Tax-free after 59 1/2 and 5-year clock |
| RMDs | Yes, age 73 | None during owner's lifetime |
| Early-withdrawal penalty | 10 percent on all amounts under 59 1/2 | 10 percent on earnings only; contributions are always penalty-free |

Frequently asked questions
What is the Traditional IRA contribution limit for 2026?
The 2026 Traditional IRA contribution limit is $7,000 per person, plus a $1,000 catch-up at age 50 and older for a total of $8,000. The limit applies to the combined Traditional plus Roth IRA contributions, not to each separately. Spouses each get their own $7,000 limit even if only one has earned income (spousal IRA rule).
Is a Traditional IRA contribution always tax-deductible?
No. If you are an active participant in a workplace retirement plan, the deduction phases out at higher Modified Adjusted Gross Income. The 2026 single-filer phase-out is $79,000 to $89,000 MAGI; married filing jointly with both spouses covered is $126,000 to $146,000. A non-active-participant spouse of a covered worker phases out from $236,000 to $246,000. Anyone with no workplace plan can deduct the full contribution at any income.
What is the difference between a Traditional IRA and a Roth IRA?
Traditional IRA contributions may be deductible now and grow tax-deferred; withdrawals are taxed as ordinary income and have Required Minimum Distributions at age 73. Roth IRA contributions are after-tax, grow tax-free, and qualified withdrawals are tax-free with no lifetime RMDs. Roth has income limits ($165,000 single MAGI phase-out start in 2026); Traditional has none for contributing but has phase-outs for the deduction.
When can I withdraw from a Traditional IRA?
You can withdraw at any time, but withdrawals before age 59 1/2 trigger a 10 percent IRS penalty plus ordinary income tax unless an exception applies. Exceptions include up to $10,000 for a first-home purchase, qualified higher-education expenses, unreimbursed medical expenses above 7.5 percent of AGI, health insurance after unemployment, total disability, and a one-per-lifetime $1,000 emergency distribution under SECURE Act 2.0.
At what age do Traditional IRA Required Minimum Distributions start?
RMDs start at age 73 for anyone turning 73 between 2023 and 2032, and rise to age 75 starting in 2033 under SECURE Act 2.0. The first RMD can be deferred to April 1 of the year after you turn 73, but every subsequent RMD is due by December 31. The amount is your prior-year-end balance divided by the IRS Uniform Lifetime Table factor (27.4 at age 73).
Can I convert a Traditional IRA to a Roth IRA?
Yes. A Roth conversion moves money from a Traditional IRA to a Roth IRA. The converted amount is fully taxable as ordinary income in the year of conversion, with no income limit on who can convert. Many savers run partial conversions in low-income years (between retirement and Social Security or RMDs) to fill up lower brackets at known rates. The pro-rata rule applies if you hold any non-deductible basis across all IRAs.
