Compare Roth IRA vs Traditional IRA — contribution limits, tax benefits, withdrawal rules, and which account wins based on your income and age.
Before comparing the two accounts, here are the numbers you need for 2026:
| Detail | 2026 Amount |
|---|---|
| Annual contribution limit (under 50) | $7,000 |
| Catch-up contribution (50+) | $1,000 additional ($8,000 total) |
| Roth IRA income phase-out (single) | $150,000–$165,000 MAGI |
| Roth IRA income phase-out (married filing jointly) | $236,000–$246,000 MAGI |
| Traditional IRA deduction phase-out (single, covered by employer plan) | $79,000–$89,000 MAGI |
| Traditional IRA deduction phase-out (MFJ, covered by employer plan) | $126,000–$136,000 MAGI |
Both account types share the same $7,000 combined limit. You can split contributions between a Roth and Traditional IRA, but your total across both cannot exceed $7,000 (or $8,000 if you're 50+).
A Traditional IRA gives you a tax deduction now and taxes withdrawals in retirement. Here's the mechanics:
Sarah earns $65,000 in 2026 and contributes $7,000 to a Traditional IRA. She's single with no employer retirement plan, so the full amount is deductible. At the 22% federal tax bracket, she saves $1,540 on her 2026 tax bill. Her taxable income drops from $65,000 to $58,000. After the $15,000 standard deduction, she's taxed on $43,000 instead of $50,000.
A Roth IRA flips the tax treatment: you pay taxes now and withdraw tax-free later.
Marcus is 30 and contributes $7,000/year to a Roth IRA for 35 years. Assuming a 7% real (inflation-adjusted) return — consistent with the historical S&P 500 average — his account grows to approximately $1,065,000 in today's dollars. Every dollar of that is tax-free. If he'd used a Traditional IRA instead and faces a 22% tax rate in retirement, he'd owe roughly $234,000 in taxes on withdrawals, keeping about $831,000.
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Tax deduction now | No | Yes (if eligible) |
| Tax-free withdrawals | Yes | No — taxed as ordinary income |
| Income limits to contribute | Yes — $150K/$236K phase-out | No (but deduction has limits) |
| Required Minimum Distributions | None | Age 73 |
| Early access to contributions | Yes — penalty-free anytime | No — 10% penalty before 59½ |
| Best for | Lower current tax bracket, younger investors | Higher current tax bracket, near-retirement |
| 2026 contribution limit | $7,000 ($8,000 if 50+) | $7,000 ($8,000 if 50+) |
Forget the generic "it depends" advice. Answer these four questions and the right choice becomes clear:
This is the most important question. The 2026 federal tax brackets are: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
The younger you are, the more the Roth IRA wins. A 25-year-old has 40 years of tax-free compound growth ahead. That's decades of dividends, capital gains, and interest that will never be taxed. A 58-year-old has 7 years — the tax-deferred growth advantage is smaller, and the immediate deduction from a Traditional IRA has more impact.
If you're covered by a 401(k) at work and your income exceeds the deduction phase-out ($79,000–$89,000 single in 2026), your Traditional IRA contributions are not deductible. In that case, a non-deductible Traditional IRA is almost always worse than a Roth IRA. You'd be paying taxes on contributions and on withdrawals of the earnings.
Roth IRA contributions (not earnings) can be withdrawn at any time, tax- and penalty-free. This makes the Roth IRA a dual-purpose account — retirement savings with an emergency backstop. A Traditional IRA locks your money away until 59½ with a 10% penalty for early access.
If your income exceeds the Roth IRA limits ($165,000 single / $246,000 MFJ in 2026), you can still get money into a Roth through the "backdoor" method:
Warning: The pro-rata rule applies. If you have existing pre-tax Traditional IRA balances, the conversion is taxed proportionally across all your Traditional IRA money — not just the non-deductible contribution. If you have $93,000 in a pre-tax Traditional IRA and convert a $7,000 non-deductible contribution, 93% of the conversion is taxable. Roll existing pre-tax IRA balances into your employer 401(k) first to avoid this.
Yes. You can split your $7,000 between a Roth and Traditional IRA in any proportion. Some strategies:
The best approach for most people under 50: max your employer 401(k) match, then max a Roth IRA ($7,000), then go back and increase 401(k) contributions. This gives you both pre-tax and post-tax retirement money — essential tax diversification. For more on building a diversified portfolio, see our guide to the best ETFs for beginners.
Let's run the numbers for someone investing $7,000/year for 30 years at a 7% real return, using a dollar-cost averaging strategy:
| Scenario | Account Balance at 30 Years | After-Tax Value (22% bracket) |
|---|---|---|
| Roth IRA | $661,226 | $661,226 (all tax-free) |
| Traditional IRA | $661,226 | $515,756 (after 22% tax on withdrawals) |
| Traditional IRA (12% bracket in retirement) | $661,226 | $581,879 (after 12% tax) |
If your retirement tax rate is the same as your current rate, the Roth always wins because you avoid taxes on the growth. The Traditional IRA only wins when your retirement tax rate is meaningfully lower — a drop from 22% to 12%, for example, narrows the Roth advantage considerably.
Yes. You can contribute to both in the same year, but the combined total cannot exceed $7,000 ($8,000 if you're 50 or older). Many investors use both account types for tax diversification — pre-tax money in a Traditional IRA or 401(k), and after-tax money in a Roth IRA.
You'll owe a 6% excess contribution penalty for each year the money stays in the Roth. To fix it, you can either withdraw the excess contribution (and any earnings on it) before your tax filing deadline, or recharacterize it as a Traditional IRA contribution. Going forward, use the Backdoor Roth method if your income is above the phase-out.
You have until the tax filing deadline — April 15, 2027 — to make IRA contributions for the 2026 tax year. However, contributing earlier in the year gives your money more time to grow. A January contribution has nearly 15 extra months of growth compared to an April-of-next-year contribution.
Yes. A Roth conversion moves money from a Traditional IRA to a Roth IRA. You'll owe income taxes on the converted amount in the year of conversion, but all future growth is tax-free. This is especially powerful in years when your income is temporarily low (job change, sabbatical, early retirement before Social Security kicks in). There's no income limit or cap on conversion amounts.
If you believe federal tax rates will increase — which many financial planners expect given the national debt trajectory — the Roth IRA becomes more attractive. You're paying taxes at today's known rate and locking in tax-free treatment for all future growth and withdrawals, regardless of what Congress does to tax rates in 2040 or 2050.
