If you are saving for retirement in the United States, the Roth IRA and the Traditional IRA are the two most common individual retirement accounts. They share the same 2026 contribution limit, but they tax you at opposite ends of the journey: the Traditional IRA can give you a tax break now and taxes your withdrawals later, while the Roth IRA taxes your contributions now and lets qualified withdrawals come out tax-free.
Neither account is better in every situation. The right choice depends mainly on your tax rate today compared with the tax rate you expect in retirement, plus your income, your age, and whether you have a workplace retirement plan. This guide walks through the 2026 IRS numbers, a side-by-side comparison, and two worked examples so you can see how the math actually plays out.
How Each Account Works
Traditional IRA. You contribute money that may be tax-deductible in the year you contribute, depending on your income and whether you (or your spouse) are covered by a workplace retirement plan. The money grows tax-deferred, and withdrawals in retirement are taxed as ordinary income. The IRS generally requires you to start taking required minimum distributions (RMDs) from a Traditional IRA at age 73.
Roth IRA. You contribute money you have already paid tax on, so there is no deduction. The money grows tax-free, and qualified withdrawals in retirement are tax-free. The original owner of a Roth IRA is not required to take withdrawals during their lifetime. A qualified distribution generally requires that you are at least 59½ years old and that the 5-year holding period has been met.
The 2026 Numbers (IRS)
The IRS raised IRA limits for 2026 in Notice 2025-67. The contribution limit applies to your total contributions across all Traditional and Roth IRAs you hold — it is not $7,500 per account.
| 2026 Rule | Amount |
|---|---|
| IRA contribution limit (under age 50) | $7,500 |
| Catch-up contribution (age 50+) | $1,100 |
| Total limit (age 50+) | $8,600 |
| 401(k) employee deferral limit (for context) | $24,500 |
Income Phase-Out Ranges for 2026
Income limits use modified adjusted gross income (MAGI). There are two different tests, and people often confuse them:
- Roth IRA contributions: your ability to contribute directly phases out with income. There is no income test for making a Traditional IRA contribution, but there is one for deducting it.
- Traditional IRA deduction: if you or your spouse are covered by a workplace retirement plan, your deduction phases out with income. If neither of you is covered by a workplace plan, the deduction phase-out does not apply.
| 2026 Phase-Out Range | Single / Head of Household | Married Filing Jointly |
|---|---|---|
| Roth IRA contribution | $153,000 – $168,000 | $242,000 – $252,000 |
| Traditional IRA deduction (contributing spouse covered by workplace plan) | $81,000 – $91,000 | $129,000 – $149,000 |
| Traditional IRA deduction (contributor not covered, spouse covered) | n/a | $242,000 – $252,000 |
| Married filing separately (either test) | $0 – $10,000 | $0 – $10,000 |
Roth IRA vs Traditional IRA: Side-by-Side Comparison
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Tax treatment of contributions | May be deductible (pre-tax if deductible) | After-tax, no deduction |
| Tax treatment of growth | Tax-deferred | Tax-free |
| Tax treatment of qualified withdrawals | Taxed as ordinary income | Tax-free (if 59½ and 5-year rule met) |
| 2026 contribution limit | $7,500 ($8,600 if age 50+) | $7,500 ($8,600 if age 50+) |
| Income limit on contributing | None | Phases out at $153,000–$168,000 single / $242,000–$252,000 MFJ |
| Income limit on deduction (if covered by workplace plan) | Phases out at $81,000–$91,000 single / $129,000–$149,000 MFJ | Not applicable |
| Required minimum distributions | Yes, generally starting at age 73 | None for the original owner |
| Early withdrawal (before 59½) | Taxable distributions may face an additional 10% tax, with exceptions | Contributions can be withdrawn anytime tax-free; earnings on nonqualified distributions are taxable and may face the additional 10% tax |
Worked Example 1: Early-Career Saver in a Moderate Bracket
Assumptions: Maya is 32, single, has a MAGI of $85,000, and is not covered by a workplace retirement plan. Her marginal federal tax rate is 22%. She contributes the full $7,500 to an IRA in 2026. For illustration, assume the investment quadruples to $30,000 by the time she withdraws it, and her marginal federal rate in retirement is 12%. State taxes, fees, and inflation are ignored for simplicity.
If she chooses a Traditional IRA: Because she is not covered by a workplace plan, her contribution is fully deductible. She saves $7,500 × 22% = $1,650 in federal tax this year. At withdrawal, the $30,000 is taxed as ordinary income at 12%, so she pays $3,600 and keeps $26,400. Counting the $1,650 tax saving as cash kept aside (not reinvested), her total value is $26,400 + $1,650 = $28,050.
If she chooses a Roth IRA: She gets no deduction, so the $7,500 costs her the full $7,500 after tax. At withdrawal, the $30,000 comes out tax-free, so she keeps the full $30,000.
Takeaway: In this example, the Roth IRA ends up about $1,950 ahead on these equal-nominal-contribution terms — and the Traditional IRA's tax bill lands on the grown balance, not just the original contribution. Note that this comparison puts the same nominal $7,500 into each account, but the Roth contribution is made with after-tax dollars — $7,500 after-tax is equivalent to about $9,615 pre-tax at a 22% rate — so the Roth side starts with more pre-tax money. The textbook comparison uses equal pre-tax amounts, and there the rule flips: the Traditional IRA wins when your retirement tax rate is lower than today's rate (you deduct at a high rate and withdraw at a low one), and the Roth IRA wins when your retirement rate is higher. If the two rates are equal, the outcomes are roughly the same. (If Maya had reinvested her $1,650 tax saving, the gap would narrow — the comparison above treats it as cash kept aside.)
Worked Example 2: High-Income Couple Near the Roth Limit
Assumptions: Daniel and Priya are both 45, married filing jointly, with a MAGI of $250,000. Daniel is covered by a workplace retirement plan; Priya is not. Both are under 50, so each has a $7,500 IRA limit. Their marginal federal rate is 24%. The exact reduced contribution is calculated using the IRS worksheet in Publication 590-A; the figures below are rounded illustrations.
Roth IRA eligibility: The 2026 Roth phase-out range for married couples filing jointly is $242,000–$252,000. Their MAGI of $250,000 sits $8,000 into a $10,000-wide range, so each spouse's direct Roth contribution is reduced to roughly 20% of the full limit: about $1,500 each ($7,500 × 20%). They cannot each contribute the full $7,500 directly to a Roth IRA.
Traditional IRA deduction: Daniel is covered by a workplace plan, and the deduction phase-out for a covered spouse filing jointly is $129,000–$149,000. At $250,000, Daniel is well above it, so his Traditional IRA contribution is not deductible. Priya is not covered, so her deduction phases out over $242,000–$252,000 — the same 20% figure applies, meaning only about $1,500 of her contribution would be deductible.
Takeaway: This couple is in the awkward middle: direct Roth contributions are sharply reduced, and Traditional deductions are mostly unavailable. Many people in this situation consider a "backdoor Roth" — making a non-deductible Traditional IRA contribution and then converting it to a Roth IRA — but conversions have their own rules, including the pro-rata rule if you hold other pre-tax IRA money. That is a situation where professional advice is worth paying for before acting.
A Simple Decision Framework
- Consider a Roth IRA first if: your current tax rate is low relative to what you expect in retirement (common early in a career), you want tax-free income in retirement, or you want to avoid lifetime RMDs.
- Consider a Traditional IRA first if: your current tax rate is high and you expect it to drop in retirement, and you can actually claim the deduction (check the phase-out ranges — a Traditional contribution you cannot deduct is usually the worst of both worlds).
- Consider splitting if: you are unsure about future tax rates, or you want some taxable and some tax-free money in retirement to manage your tax bracket year by year.
Common Mistakes to Avoid
- Assuming a Traditional IRA contribution is always deductible. If you or your spouse are covered by a workplace plan, check the phase-out ranges above. A non-deductible contribution is still allowed, but it does not give you the upfront tax break.
- Forgetting the limit is shared. The $7,500 limit covers all your Traditional and Roth IRAs combined. Contributing $7,500 to each would be an excess contribution.
- Ignoring the Roth 5-year rule. Even after 59½, earnings are only tax-free on qualified distributions, which generally require the 5-year holding period to be met.
- Missing the income test entirely. Contributing to a Roth IRA above the phase-out range creates an excess contribution that must be corrected. If your income is near the boundary, check your MAGI before contributing.
The Bottom Line
For 2026, the question is less "which account is better" and more "which tax timing fits your life." Pay tax now with a Roth IRA if you expect your rate to rise; take the deduction with a Traditional IRA if you expect it to fall and you are eligible to deduct. Either way, contributing up to the limit and investing it beats debating the perfect choice while your money sits in cash.

Frequently Asked Questions
What is the difference between a Roth IRA and a Traditional IRA?
A Traditional IRA may give you a tax deduction in the year you contribute, and withdrawals in retirement are taxed as ordinary income. A Roth IRA uses after-tax contributions, and qualified withdrawals in retirement are tax-free. The 2026 contribution limit is the same for both: $7,500 under age 50, $8,600 at 50 or older.
What is the IRA contribution limit for 2026?
$7,500 if you are under 50, $8,600 if you are 50 or older — and never more than your earned income for the year. The limit covers all your IRAs combined.
When does a Traditional IRA beat a Roth IRA?
On an equal pre-tax comparison, the Traditional IRA wins when your tax rate in retirement is lower than today's rate, because you deduct at a high rate and withdraw at a low one. The Roth IRA wins when your retirement rate is higher. If the two rates are equal, the outcomes are roughly the same.
What if my income is too high to contribute to a Roth IRA?
For 2026, direct Roth IRA contributions phase out at $153,000–$168,000 of MAGI for single filers and $242,000–$252,000 for married couples filing jointly. Many people in that situation consider a backdoor Roth, but conversions have their own rules, including the pro-rata rule if you hold other pre-tax IRA money.
