Traditional vs. Roth IRA: How to Choose, and What the 2026 Limits Actually Mean

Educational guide — the two main IRA types, current contribution limits, and who actually qualifies

An IRA (Individual Retirement Arrangement) is one of the most common ways to save for retirement outside of a workplace plan — but the rules around who can contribute, how much, and whether it's deductible trip up a lot of people. Here's how the two main types actually work.

The Core Difference: When You Pay Tax

• Traditional IRA — contributions may be tax-deductible now; the money grows tax-deferred; you pay ordinary income tax when you withdraw it in retirement.
• Roth IRA — contributions are made with after-tax dollars (no upfront deduction); the money grows tax-free, and qualified withdrawals in retirement are completely tax-free — including all the investment growth.

In short: Traditional IRA defers the tax bill to retirement; Roth IRA pays the tax now and locks in tax-free growth. Which is better depends heavily on whether you expect your tax rate to be higher or lower in retirement than it is today.

2026 Contribution Limits

• Maximum contribution: $7,500 (up from $7,000 in 2025), combined across all your Traditional and Roth IRAs — you cannot contribute $7,500 to each.
• Catch-up contribution (age 50+): an additional $1,100, bringing the total to $8,600 for those 50 and older.
• You also can't contribute more than your actual earned income for the year — if you earned $5,000, your max contribution is $5,000, regardless of the general limit.

Traditional IRA: Deductibility Depends on Workplace Coverage

Anyone with earned income can contribute to a Traditional IRA — there's no income limit on contributing. But whether that contribution is tax-deductible depends on whether you (or your spouse) are covered by a retirement plan at work:

• If neither you nor your spouse is covered by a workplace plan: your full contribution is deductible, regardless of income.
• If you're covered by a workplace plan, 2026 deduction phases out between:
  • $81,000–$91,000 (single filers)
  • $129,000–$149,000 (married filing jointly, when the contributing spouse is the one covered)
• If you're not covered, but your spouse is: the phase-out range is much higher — $242,000–$252,000 (married filing jointly).
• Married filing separately, if covered: phase-out range is $0–$10,000 — this one is not adjusted for inflation and stays very tight.

Above the top of the applicable range, the contribution is still allowed — it simply isn't deductible. A non-deductible Traditional IRA contribution still grows tax-deferred, and you'll need to track your basis (using Form 8606) so you aren't taxed twice on the same money when you eventually withdraw it.

Roth IRA: Deductibility Isn't the Question — Eligibility Is

Roth IRA contributions are never tax-deductible (they're after-tax by design), but your ability to contribute at all depends on your income:

• 2026 phase-out range: $153,000–$168,000 (single or head of household)
• 2026 phase-out range: $242,000–$252,000 (married filing jointly)
• Married filing separately (living with spouse): $0–$10,000 — again, not inflation-adjusted

Below the bottom of the range, you can contribute the full amount. Above the top, you can't contribute directly at all — though a workaround exists (see below).

The Backdoor Roth: A Workaround for High Earners

If your income is too high to contribute to a Roth IRA directly, a common strategy — often called a "backdoor Roth" — involves making a non-deductible contribution to a Traditional IRA, then converting those funds to a Roth IRA. There's no income limit on Roth conversions, only on direct Roth contributions, which is what makes this workaround possible.

The catch: the pro-rata rule. If you have other pre-tax money sitting in any Traditional IRA (from old rollovers, deductible contributions in prior years, etc.), the conversion is taxed proportionally across all your Traditional IRA balances — not just the new non-deductible contribution. This can turn what was meant to be a tax-free conversion into a partially taxable one. This strategy works most cleanly for people who have no other pre-tax IRA balances at all.

Which One Should You Actually Choose?

A few rules of thumb:

• Expect to be in a lower tax bracket in retirement than you are now? Traditional IRA's upfront deduction is generally more valuable.
• Expect to be in the same or higher tax bracket in retirement, or want to lock in today's rates? Roth IRA's tax-free growth and withdrawals are generally more valuable.
• Early in your career, in a low tax bracket now? Roth is often favored — you're paying tax at a low rate now in exchange for tax-free growth for decades.
• Want flexibility to withdraw contributions penalty-free before retirement in an emergency? Roth IRA contributions (not earnings) can generally be withdrawn at any time without tax or penalty — Traditional IRA withdrawals before 59½ generally trigger both tax and a 10% penalty, with limited exceptions.

You don't have to choose exclusively — many people contribute to both, splitting the combined $7,500/$8,600 limit however makes sense for their situation.

If You're Self-Employed: IRAs Are Just the Starting Point

If you're self-employed or a small business owner, a standard IRA's $7,500 limit is often far smaller than what's available through self-employed retirement options. A SEP-IRA or a solo 401(k), for example, can allow total contributions up to roughly $72,000 for 2026 (limits depend on your compensation and plan type) — dramatically more retirement savings capacity than a standard IRA alone. If you've read this site's guide comparing S-corp, LLC, and C-corp structures, this is one more factor that interacts with entity choice: how you pay yourself (salary vs. distribution) affects how much you can contribute to certain self-employed retirement plans.
