Traditional IRA vs Roth IRA: Decision Guide by Income
The traditional vs Roth question comes down to one thing: do you want a tax break now or in retirement? This guide gives you the answer based on your actual income, not generic advice.
The Core Difference
| Traditional IRA | Roth IRA | |
|---|---|---|
| Tax break | Deduct contributions now, pay tax on withdrawals later | No deduction now, withdrawals are completely tax-free |
| 2026 contribution limit | ||
| Required minimum distributions | Yes, starting at 73 | No RMDs ever (for original owner) |
| Early withdrawal | 10% penalty + taxes on earnings before 59½ | Contributions can be withdrawn anytime, tax/penalty-free. Earnings: 5-year rule + age 59½ |
| Income limits for contribution | None (but deduction phases out) |
Decision by Income Level (2026, Single Filer)
Under $50,000 AGI
Choose: Roth IRA
You’re in the 12% federal bracket. Paying 12% tax on contributions now is a bargain — in retirement, you’ll likely be in the same or higher bracket, especially if you build wealth over decades. Tax-free growth and zero RMDs make Roth the clear winner at low incomes.
$50,000 - $83,000 AGI (with employer plan)
Choose: Either works — lean Roth
Your traditional IRA deduction is still fully available (under $83K threshold with an employer plan). The 22% bracket makes the traditional deduction more valuable, but Roth’s lifetime benefits (no RMDs, tax-free growth) still win for most people under 40.
Split strategy: Contribute to traditional 401(k) at work (get the deduction at 22%) and Roth IRA (diversify your tax exposure).
$83,000 - $93,000 AGI (with employer plan)
Choose: Roth IRA
Your traditional IRA deduction phases out in this range. A partial deduction isn’t worth the complexity. Roth contributions are still fully available.
$93,000 - $150,000 AGI
Choose: Roth IRA
No traditional IRA deduction (if you have an employer plan), but you’re under the Roth income limit. Roth is the obvious choice.
$150,000 - $165,000 AGI
Choose: Backdoor Roth IRA
Roth contribution phases out. Use the backdoor strategy: contribute to a non-deductible traditional IRA, then convert to Roth. Legal, well-established, IRS-approved.
Warning: If you have existing pre-tax IRA balances, the pro-rata rule makes backdoor Roth partially taxable. Roll pre-tax IRA money into your 401(k) first to avoid this.
Over $165,000 AGI
Choose: Backdoor Roth IRA
Same strategy. You can’t contribute directly to either a deductible traditional or Roth. Backdoor Roth is the way.
Self-Employed at Any Income
Consider: SEP IRA or Solo 401(k) first
These allow much higher contributions ($69K for SEP, $69K+ for Solo 401k). Max these out, then use backdoor Roth for additional savings. See Best IRA Accounts Compared: Traditional vs Roth vs SEP for the full breakdown.
The Tax Diversification Strategy
The smartest approach isn’t either/or — it’s both.
Having money in traditional (tax-deferred) AND Roth (tax-free) accounts gives you flexibility in retirement:
- Low-income years: Withdraw from traditional (pay low or 0% tax via standard deduction)
- High-income years: Withdraw from Roth (avoids bumping into higher brackets)
- Medicare premium management: Roth withdrawals don’t count toward IRMAA thresholds
- Social Security taxation: Roth withdrawals don’t count toward the income that triggers Social Security tax
Practical implementation: Traditional 401(k) at work + Roth IRA personally. Or split your 401(k) 50/50 between traditional and Roth if your plan offers both.
Roth Conversion: The Power Move
Already have a large traditional IRA? Consider systematic Roth conversions:
- Convert a portion each year (stay within your current bracket)
- Pay income tax on the converted amount now
- All future growth is tax-free in the Roth
Best conversion years:
- Early retirement (before Social Security and RMDs start)
- Career transition or sabbatical
- Years with large deductions
- Before tax rates potentially increase
The 5-year rule: Each Roth conversion has its own 5-year waiting period for tax-free withdrawal of the converted amount (if under 59½). Contributions can always be withdrawn immediately.
Common Mistakes
- Not contributing because you can’t decide: Roth vs traditional is a 10-20% optimization. Not contributing at all is a 100% loss. If you’re paralyzed by the choice, just pick Roth.
- Forgetting the pro-rata rule: Backdoor Roth doesn’t work cleanly if you have pre-tax IRA balances. Roll them to a 401(k) first.
- Ignoring state taxes: If you’re in a high-tax state now but plan to retire in a no-tax state, traditional becomes more attractive (deduct at high rate now, withdraw at 0% state rate later).
- Converting too much at once: Large Roth conversions push you into higher brackets. Spread them across multiple years.
Key Takeaways
- Under $50K income: Roth IRA, almost always
- $50K-$93K with employer plan: Roth or split strategy
- Over $150K: Backdoor Roth
- Tax diversification (some traditional, some Roth) is the optimal long-term strategy
- When in doubt, choose Roth — tax-free growth is extremely valuable over decades
