Quick summary — main differences
- Traditional IRA: Contributions may be tax-deductible now (depending on income and employer plan participation). Withdrawals in retirement are taxed as ordinary income. Required Minimum Distributions (RMDs) apply (subject to current law).
- Roth IRA: Contributions are made with after-tax dollars (no tax deduction today). Qualified withdrawals in retirement are tax-free, and there are no RMDs during the original owner’s lifetime. However, direct Roth contributions are limited by income.
2025 contribution limits & basic rules
The annual combined contribution limit for Traditional and Roth IRAs for 2025 is $7,000 if you are under age 50, and $8,000 if you are age 50 or older (includes the $1,000 catch-up). Your total contributions to all IRAs (Roth + Traditional) cannot exceed these limits or your taxable compensation.
Roth IRA income eligibility (2025)
Whether you can contribute directly to a Roth IRA depends on your Modified Adjusted Gross Income (MAGI) and filing status. For 2025:
- Single / Head of Household: Full contribution if MAGI < $150,000; partial contribution if $150,000 ≤ MAGI < $165,000; no direct contribution at MAGI ≥ $165,000.
- Married Filing Jointly: Full contribution if MAGI < $236,000; partial if $236,000 ≤ MAGI < $246,000; no direct contribution at MAGI ≥ $246,000.
Traditional IRA deduction rules (2025)
Contributions to a Traditional IRA may be tax-deductible depending on whether you (or your spouse) are covered by a retirement plan at work and your MAGI. If neither spouse is covered by a workplace retirement plan, the deduction is usually fully allowed regardless of income. If covered, phase-outs apply — consult IRS charts or your tax advisor to see where you fall.
How taxation works — now vs later
The core trade-off is tax today vs tax later:
- Traditional IRA: You may reduce taxable income today via a deductible contribution, lowering current income tax. Taxes are paid on withdrawals in retirement at ordinary income tax rates.
- Roth IRA: You pay taxes on contributions now (no deduction), but qualified withdrawals in retirement are tax-free — both contributions and earnings (subject to rules). Roths also provide tax flexibility in retirement and no RMDs for the original owner.
Withdrawals, penalties & exceptions
Both account types have rules about early withdrawals (before age 59½) and special exceptions. Key points:
- Traditional IRA: Withdrawals are taxed; early withdrawals may incur a 10% penalty unless an exception applies (first home, certain medical expenses, etc.).
- Roth IRA: You can always withdraw your contributions tax- and penalty-free. To withdraw earnings tax-free, the Roth account must meet the 5-year rule and you must be age 59½ (or meet another qualifying exception). This makes Roths more flexible for certain emergencies.
Required Minimum Distributions (RMDs) & estate planning
Traditional IRAs generally require RMDs starting at a specified age set by law (rules changed in recent years — check the current RMD start age for your tax year). Roth IRAs do not require RMDs during the original owner's lifetime, which can be an advantage for estate planning and tax control in retirement.
Roth conversions & the backdoor Roth
If your income is too high for direct Roth contributions, a common strategy is the backdoor Roth: contribute to a Traditional IRA (non-deductible if necessary) and convert that balance to a Roth IRA. Conversions can create taxable income if pre-tax amounts are converted, and the pro-rata rule can complicate tax calculations when you hold other pre-tax IRA balances. Always run the numbers or consult a tax pro before converting.
Side-by-side comparison table
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Tax treatment of contributions | Pre-tax (possibly deductible now) | After-tax (no deduction) |
| Tax on withdrawals | Taxed as ordinary income | Tax-free (if qualified) |
| Income limits to contribute | No contribution limit (deductibility may be limited) | Yes — contributions phase out at higher MAGI levels in 2025. |
| RMDs | Yes (age threshold applies) | No for original owner |
| Early withdrawal flexibility | Less flexible; penalties apply | Contributions can be withdrawn anytime tax- & penalty-free |
| Best if you expect | Lower tax rates in retirement | Higher tax rates in retirement or need tax-free withdrawals |
Which IRA is better? A simple decision flow
Answer these questions in order to help choose:
- Do you expect your tax rate in retirement to be lower than today? — If yes, Traditional IRA might make sense. If no or unsure, Roth is often preferred.
- Do you need a tax deduction now? — If current tax relief is important, Traditional IRA may be attractive (if deductible).
- Are you a high-income earner blocked from direct Roth contributions? — Consider a backdoor Roth, but check the pro-rata rule and conversion tax consequences first.
- Do you value tax-free withdrawals and estate planning flexibility? — Roth IRAs usually provide those benefits.
Real-world examples (illustrative)
Example 1 — Young professional (age 30) expecting higher future income
Sam (age 30) is in a 22% tax bracket and expects to be in a higher bracket later. Sam contributes to a Roth IRA because paying tax now at a lower rate and enjoying tax-free withdrawals in decades is preferable.
Example 2 — Near-retiree (age 60) who wants current tax relief
Lisa (age 60) is in a 32% tax bracket and expects to have lower taxable income in retirement. A Traditional IRA (or maximizing deductible contributions) could reduce her current taxes; she may also consider partial Roth conversions in low-tax years.
Example 3 — High earner (MAGI > Roth limits)
Jordan earns too much for direct Roth contributions. He uses a backdoor Roth by contributing to a Traditional IRA (non-deductible) then converting to a Roth, but must account for other pre-tax IRA balances due to the pro-rata rule. Professional tax advice is recommended.
Tax tips & practical rules to follow
- Coordinate IRA contributions: The $7,000/$8,000 limit applies to all IRAs combined — you can't contribute $7,000 to a Roth and $7,000 to a Traditional separately.
- Check your MAGI before contributing to a Roth: If you’re near the phase-out range, your allowed contribution may be reduced — annual IRS tables show exact thresholds.
- Consider employer plans first: If you have access to a 401(k) with employer match, prioritize the match — it's usually the best immediate return.
- Be mindful of conversions timing: Converting large pre-tax balances to a Roth in a single year may create a large tax bill; stagger conversions to manage tax brackets.
Common mistakes to avoid
- Assuming Roth is always better — if you need current tax relief, Traditional may be preferable.
- Ignoring the pro-rata rule on conversions — it can make backdoor Roth conversions taxable if you have pre-tax IRA balances.
- Overlooking the combined contribution limit — you can’t double-dip into both accounts beyond the annual cap.
Checklist — what to do this year
- Check 2025 contribution limits and your eligibility (you can contribute for 2025 until the filing deadline in 2026 if applicable).
- Estimate your MAGI and see if you qualify for direct Roth contributions or full Traditional deduction.
- Max employer 401(k) match (if available) before investing in IRAs.
- If considering a backdoor Roth, plan conversions carefully and consult a tax advisor if you have other IRA pre-tax balances.
Frequently Asked Questions (FAQ)
Q: Can I contribute to both a Roth IRA and a Traditional IRA in the same year?
A: Yes — but the total combined contribution to all your IRAs cannot exceed the annual limit ($7,000 or $8,000 for those 50+ in 2025).
Q: Are Roth IRA withdrawals always tax-free?
A: Qualified withdrawals — typically after age 59½ and after the account has met the 5-year rule — are tax-free. Withdrawing earnings before meeting the rules may result in tax and penalties. Contributions (your basis) can generally be withdrawn tax- and penalty-free at any time.
Q: What is the pro-rata rule?
A: When you convert Traditional IRA funds to a Roth, the IRS considers the proportion of pre-tax vs after-tax money across all your IRAs — not just the account you convert. That means if you have other pre-tax IRA balances, part of a conversion may be taxable under the pro-rata rule.
Q: Can I change my mind and recharacterize a conversion?
A: Recharacterizations (undoing a conversion) were largely eliminated for conversions under rules enacted years ago — current rules generally don't allow recharacterizing a Roth conversion back to a Traditional IRA. Always check current IRS guidance or ask a tax pro.
