The Roth IRA and Traditional IRA are the two most important individual retirement accounts. The choice between them comes down to one question: do you want to pay taxes now or later?

2026 IRA Contribution Limits
| Category | Limit |
|---|---|
| Under age 50 | $7,000 |
| Age 50 and older | $8,000 |
| Combined limit (all IRAs) | $7,000/$8,000 |
| Must have earned income | Yes |
You can split contributions between Roth and Traditional IRAs, but your total cannot exceed the annual limit.
Roth IRA Income Limits (2026)
You must earn below these thresholds to contribute directly to a Roth IRA:
| Filing Status | Full Contribution | Reduced Contribution | No Contribution |
|---|---|---|---|
| Single/HoH | Under $150,000 | $150,000–$165,000 | Over $165,000 |
| Married Filing Jointly | Under $236,000 | $236,000–$246,000 | Over $246,000 |
| Married Filing Separately | — | $0–$10,000 | Over $10,000 |
Backdoor Roth IRA: If your income exceeds these limits, you can contribute to a nondeductible Traditional IRA and then convert to a Roth IRA. This “backdoor” strategy has no income limit.
Traditional IRA Deductibility
Whether your Traditional IRA contributions are tax-deductible depends on whether you (or your spouse) are covered by an employer retirement plan:
If You Have a 401(k) at Work
| Filing Status | Full Deduction | Partial Deduction | No Deduction |
|---|---|---|---|
| Single | Under $79,000 | $79,000–$89,000 | Over $89,000 |
| Married Filing Jointly | Under $126,000 | $126,000–$146,000 | Over $146,000 |
If You Don’t Have a 401(k) at Work
Your Traditional IRA contribution is fully deductible at any income level (unless your spouse has a plan, in which case different limits apply).
Which Is Better: A Detailed Comparison
Scenario 1: Young Worker, $55,000 Income (22% bracket)
| Traditional IRA | Roth IRA | |
|---|---|---|
| Contribute $7,000 | Tax savings: $1,540 | No tax savings |
| Grows to $75,000 over 30 years | Taxable at withdrawal | Tax-free at withdrawal |
| Withdraw $75,000 in retirement (12% bracket) | Tax: $9,000 | Tax: $0 |
| Net benefit | Roth wins by $7,460 |
When you expect to be in a lower bracket in retirement (unlikely for many young workers who will see income grow), Traditional wins. But if your bracket stays the same or increases, Roth wins.
Scenario 2: Peak Earner, $200,000 Income (32% bracket)
| Traditional IRA | Roth IRA | |
|---|---|---|
| Contribute $7,000 | Tax savings: $2,240 | No tax savings |
| Grows to $75,000 over 30 years | Taxable at withdrawal | Tax-free at withdrawal |
| Withdraw $75,000 in retirement (22% bracket) | Tax: $16,500 | Tax: $0 |
| Reinvest tax savings at Traditional | ~$24,000 growth | N/A |
| Net benefit | Traditional wins by ~$5,260 |
At high incomes where you’re confident your retirement bracket will be lower, Traditional provides more value.
Five Reasons to Choose a Roth IRA
- Tax-free growth forever — No taxes on decades of compound growth
- No RMDs — No required distributions; your money can grow tax-free for life
- Contribution access — Withdraw contributions (not earnings) anytime without penalty
- Tax diversification — Having both pre-tax and post-tax retirement accounts gives flexibility
- Best for young investors — Lower tax bracket now + decades of tax-free growth = maximum benefit
Five Reasons to Choose a Traditional IRA
- Immediate tax deduction — Reduces your tax bill today
- Higher current bracket — If you’re in the 32%+ bracket now and expect 22% in retirement, the deduction is worth more than the future tax savings
- Tax arbitrage — The spread between your current and retirement tax rates creates value
- State tax savings — If you live in a high-tax state now but plan to retire in a no-tax state
- Employer plan + high income — If a Roth IRA isn’t available due to income limits and you don’t want to do a backdoor conversion
The Backdoor Roth IRA Strategy
For high earners above the Roth income limits:
- Contribute $7,000 to a nondeductible Traditional IRA
- Convert the Traditional IRA to a Roth IRA shortly after
- Pay tax only on any gains between contribution and conversion (minimal if done quickly)
- Result: $7,000 in a Roth IRA regardless of income level
Caution: The pro-rata rule applies if you have existing pre-tax IRA balances. The conversion is taxed based on the ratio of pre-tax to post-tax money across all your IRAs.
Roth IRA: The Ultimate Retirement Account
The Roth IRA is often called the best retirement account in the tax code because:
- Contributions can be withdrawn anytime (great emergency fund backstop)
- No RMDs mean you can leave the full balance to heirs
- Inherited Roth IRAs are tax-free for beneficiaries
- Tax-free growth for potentially 60+ years (if started in your 20s)
If you can afford the tax hit now, the Roth IRA is almost always the better long-term choice for investors under 40.
