Roth IRA vs Traditional IRA: Which Should You Choose in 2026

A 25-year-old contributing $7,500 per year to a Roth IRA at 7% average annual returns will have $1.13 million by age 65. Every dollar of growth is tax-free. No capital gains tax, no ordinary income tax, no required minimum distributions. That is the power of a Roth IRA, and it is why 95% of Gen Z IRA contributions went into Roth accounts in Q3 2025, according to Fidelity.

But Roth is not always the right answer. If you are 50 years old earning $250,000 and in the 35% tax bracket, a traditional IRA deduction saves you $2,625 in taxes today. In retirement, you might withdraw that money in the 22% bracket, paying only $1,650. The traditional IRA wins by $975 in that scenario.

This guide breaks down how each account works, the 2026 contribution limits and income phase-outs, and a decision framework for choosing the right one.

How Each Account Works

Roth IRA

You contribute after-tax dollars. The money grows tax-free. Qualified withdrawals in retirement are tax-free. There are no required minimum distributions (RMDs) during your lifetime. You can withdraw your contributions (but not earnings) at any time without taxes or penalties.

The catch: there are income limits. In 2026, single filers with modified adjusted gross income (MAGI) above $168,000 cannot contribute directly to a Roth IRA. Married filing jointly couples above $252,000 are also locked out. See our Roth IRA glossary term for the full rules.

Traditional IRA

You contribute pre-tax dollars (if eligible for the deduction). The money grows tax-deferred. Withdrawals in retirement are taxed as ordinary income. RMDs begin at age 73 (or 75 if you were born in 1960 or later).

Anyone with earned income can contribute to a traditional IRA. There is no income limit to contribute. But the deductibility of your contribution phases out if you (or your spouse) are covered by a workplace retirement plan like a 401(k).

2026 Contribution Limits and Income Phase-Outs

The IRS sets the IRA contribution limit annually. For 2026:

• Under 50: $7,500 per person
• Age 50 or older: $8,600 per person (includes $1,100 catch-up)
• Deadline: April 15, 2027 for 2026 contributions

The $7,500 limit is shared across all your IRAs combined. You cannot put $7,500 in a Roth and another $7,500 in a traditional. You can split it any way you want, but the total cannot exceed $7,500.

Roth IRA Income Phase-Outs (2026)

If your income falls in the phase-out range, you can contribute a reduced amount. If you are above the range, you cannot contribute directly, but you can use the backdoor Roth strategy.

Traditional IRA Deduction Phase-Outs (2026)

If you are covered by a workplace retirement plan:

If neither you nor your spouse is covered by a workplace plan, you can deduct the full contribution at any income level.

Roth vs Traditional: The Decision Framework

The core question is simple: do you want to pay taxes now or later?

Choose Roth If:

• You are early in your career and expect your income (and tax rate) to rise
• Your marginal tax rate is 22% or lower
• You want tax-free withdrawals in retirement with no RMDs
• You value the flexibility of withdrawing contributions before retirement
• You believe tax rates will increase in the future
• Your MAGI is under $153,000 (single) or $242,000 (MFJ)

Choose Traditional If:

• You are in your peak earning years with a high marginal tax rate (32% or higher)
• You expect your tax rate to drop in retirement
• You are covered by a workplace plan and your income is low enough to deduct the contribution
• You want to reduce your taxable income this year
• You plan to do Roth conversions later when your income drops

Choose Both (Tax Diversification)

Nothing stops you from splitting your $7,500 across both accounts. In retirement, you can withdraw from the traditional IRA up to the top of a low tax bracket, then pull tax-free dollars from the Roth for anything above that. This gives you control over your effective tax rate in retirement.

Real-World Examples

Example 1: The 25-Year-Old Software Engineer

Priya, 25, earns $85,000 as a software developer. She is in the 22% marginal tax bracket. Her income will likely rise significantly over her career.

She chooses Roth. At 22%, the tax cost of contributing after-tax dollars is manageable. By retirement, she expects to be in the 24% or 32% bracket. Paying 22% now beats paying 32% later. She also values the ability to withdraw her contributions if she needs to buy a house or start a business.

If she contributes $7,500 per year for 40 years at 7% returns, she will have approximately $1.6 million, all tax-free. Use our Roth vs Traditional IRA calculator to model your own numbers.

Example 2: The 52-Year-Old Executive

Robert, 52, earns $310,000 as a VP of Sales. He is in the 35% bracket. His income is too high for a direct Roth contribution, and too high for a traditional IRA deduction (he is covered by his employer's 401(k)).

He uses the backdoor Roth strategy: he contributes $8,600 (catch-up included) to a non-deductible traditional IRA, then immediately converts it to a Roth IRA. Since the contribution was non-deductible, the conversion has no tax consequence (assuming he has no other traditional IRA balance with pre-tax money). He gets Roth tax-free growth despite being above the income limits.

Example 3: The 40-Year-Old Teacher

Maria, 40, earns $68,000 as a public school teacher. She is in the 12% bracket and is not covered by a workplace retirement plan (her state pension is separate).

She can deduct the full $7,500 traditional IRA contribution at any income because she has no workplace plan. But at 12%, the deduction saves her only $900 in taxes. The Roth is likely the better play: paying 12% now to lock in decades of tax-free growth is a strong trade. If she expects a pension in retirement that pushes her into the 22% bracket, the Roth becomes even more attractive.

The Backdoor Roth Strategy

If your income exceeds the Roth IRA phase-out, you can still get money into a Roth account through the backdoor method:

1. Contribute $7,500 to a non-deductible traditional IRA (no income limits on contributions, only on deductibility)
2. Immediately convert the traditional IRA to a Roth IRA
3. Since the contribution was after-tax (non-deductible), there is no tax on the conversion

The pro-rata rule applies if you have other pre-tax money in traditional IRAs. The IRS looks at all your traditional IRA balances combined. If you have $75,000 in pre-tax traditional IRA funds and contribute $7,500 non-deductible, only 9% of your conversion is tax-free. Most people using the backdoor Roth keep their traditional IRA balance at zero to avoid this issue.

Common Mistakes

Assuming You Cannot Contribute to an IRA

Many people assume they earn too much for any IRA. Anyone with earned income can contribute to a traditional IRA at any income level. The income limit only affects deductibility, not the ability to contribute. And the backdoor Roth makes the Roth income limit bypassable for most people.

Not Tracking Basis on Non-Deductible Contributions

If you make non-deductible traditional IRA contributions (for the backdoor Roth or because your income is too high for a deduction), you must file Form 8606 with your tax return. This tracks your after-tax basis. If you do not file it, the IRS has no record that you already paid taxes on that money, and you will pay taxes on it again when you withdraw or convert.

Splitting Contributions Without a Plan

Splitting $7,500 between Roth and traditional can make sense for tax diversification. But doing it randomly, without calculating your marginal rate and expected retirement rate, just creates complexity. Run the numbers first. Use our tax bracket calculator to find your current marginal rate.

Forgetting the Shared Limit

The $7,500 limit applies across all your IRAs combined. If you put $5,000 in a Roth and $4,000 in a traditional, you have over-contributed by $1,500. Excess contributions trigger a 6% penalty per year until corrected.

Conclusion

For most people in their 20s and 30s, the Roth IRA is the clear winner. You pay taxes while your rate is low, and you lock in decades of tax-free growth. For high earners in their 40s and 50s at peak income, the traditional IRA deduction (if eligible) or the backdoor Roth is the better play. The decision comes down to one comparison: your current marginal tax rate versus your expected retirement tax rate. Run that comparison using our Roth vs Traditional IRA calculator, then set up automatic contributions and let the account do its job.
