Roth vs Traditional IRA
The two most common retirement accounts work in opposite directions on taxes. Pick the right one for your situation and you can save tens of thousands of dollars over a lifetime.
The Short Answer
If your current marginal tax rate is higher than you expect it to be in retirement, favor a Traditional IRA — you get the bigger deduction today.
If your current rate is lower than you expect in retirement (or if you're uncertain and want tax diversification), favor a Roth IRA.
For most young savers in the 12–22% brackets, Roth wins. For high earners in the 32–37% brackets planning to retire on modest expenses, Traditional often wins. The break-even depends heavily on your assumptions.
Side-by-Side Comparison
| Traditional IRA | Roth IRA | |
|---|---|---|
| Contribution taxes | Pre-tax (usually deductible) | After-tax |
| Withdrawal taxes | Taxed as ordinary income | Tax-free (qualified withdrawals) |
| 2026 contribution limit | $7,000 ($8,000 if 50+) | $7,000 ($8,000 if 50+) |
| Income limits for direct contribution | None (but deduction phases out with workplace plan) | Phases out above certain thresholds |
| Required minimum distributions | Start at age 73 (or 75 per SECURE 2.0) | None during owner's lifetime |
| Early withdrawal of contributions | 10% penalty + taxes before 59½ | Contributions (not earnings) can be withdrawn anytime, tax- and penalty-free |
| Estate planning | Heirs pay income tax on withdrawals | Heirs receive tax-free (subject to 10-year rule) |
| Best for | High earners in peak bracket expecting lower retirement bracket | Young/early-career savers, anyone wanting flexibility, estate-focused retirees |
How to Think About Tax Brackets
The decision hinges on comparing your current marginal rate to your expected retirement rate. Most people underestimate how easy it is to stay in a low bracket in retirement, especially if you're aiming for FIRE with a modest lifestyle. A couple withdrawing $80,000/year in retirement only pays a 12% federal marginal rate.
If you're a single filer in the 22% bracket today but plan to retire on $50,000/year (mostly in the 12% bracket), Traditional IRA contributions save you 22 cents on the dollar now and cost you 12 cents on the dollar later — a clear Traditional win.
But if you're in the 12% bracket early in your career and expect promotions (plus decades of compounding), Roth is often better: you pay 12% now and potentially avoid 22–24% taxes later on much larger balances.
Why Roth Has Hidden Advantages
Even if the math narrowly favors Traditional, Roth has benefits that don't show up in simple break-even calculations:
Tax diversification. Having both pre-tax and Roth balances lets you manage your taxable income in retirement — pulling from whichever bucket keeps you in the optimal bracket each year.
No RMDs. You're never forced to withdraw, which is huge for estate planning and for retirees who want flexibility.
Contribution access. You can pull your Roth contributions (not earnings) out anytime, tax- and penalty-free. This makes Roth a valuable emergency-fund backup.
Hedge against rising tax rates. Current tax rates are near historic lows. If rates rise, today's Roth contributions look even better in hindsight.
What About the Backdoor Roth?
High earners whose income exceeds direct Roth contribution limits often use the "Backdoor Roth" strategy: contribute to a nondeductible Traditional IRA, then immediately convert to Roth. This is a well-established strategy with no income limits — but watch out for the pro-rata rule if you have other pre-tax Traditional IRA balances.
What This Comparison Doesn't Cover
This page compares IRA accounts. A workplace 401(k) (Traditional or Roth) has much higher contribution limits ($23,500 in 2025 before catch-up) and often comes with employer matching — typically contribute enough for the match first, then max an IRA, then return to the 401(k). State taxes, Social Security taxation of pre-tax withdrawals, and Medicare IRMAA surcharges can also tilt the decision.
