- Roth IRA = pay taxes now, withdraw tax-free in retirement. Best if you expect to be in a higher bracket later.
- Traditional IRA = deduct contributions now, pay taxes on withdrawals in retirement. Best if you're in a high bracket today.
- The 2026 contribution limit is $7,000 ($8,000 if age 50+) — shared across all your IRAs combined
- Roth IRA has income limits; high earners can use the backdoor Roth strategy
- When in doubt, choose Roth — most people under 40 benefit more from tax-free growth than a current deduction
The IRA debate is really a tax debate: do you want to pay taxes on your money now (Roth) or later (Traditional)? Neither answer is universally correct — it depends entirely on whether your tax rate will be higher today or in retirement.
This guide breaks down both accounts completely, including 2026 limits, income rules, and a clear framework for choosing.
The Core Difference: When You Pay Tax
Both IRAs invest the same assets in the same markets. The only difference is timing of taxation:
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Tax on contributions | After-tax (no deduction) | Pre-tax (deductible) |
| Tax on growth | Tax-free | Tax-deferred |
| Tax on withdrawals | Tax-free (qualified) | Taxed as income |
| Required minimum distributions | None (original owner) | Yes, starting at age 73 |
| Income limits | Yes ($165K single / $246K married) | No income limit to contribute (deductibility has limits) |
| Early withdrawal of contributions | Penalty-free anytime | 10% penalty + taxes before 59½ |
The Roth IRA: Tax-Free Growth Forever
With a Roth IRA, you contribute money you've already paid income tax on. In exchange, all future growth and qualified withdrawals are completely tax-free — including the gains, dividends, and interest earned over decades.
2026 Roth IRA income limits (MAGI):
- Single / Head of Household: Full contribution up to $150,000; phases out $150K–$165K; no contribution above $165K
- Married Filing Jointly: Full contribution up to $236,000; phases out $236K–$246K; no contribution above $246K
- You're early in your career (lower tax bracket now than you'll be in retirement)
- You want flexibility — Roth contributions (not earnings) can be withdrawn anytime without penalty
- You don't want to deal with Required Minimum Distributions in retirement
- You believe tax rates will be higher in the future
- You're under 40 and uncertain — Roth is the safer default for long time horizons
The Traditional IRA: Lower Taxes Today
A Traditional IRA lets you deduct contributions from your taxable income today (subject to income limits if you have a 401k at work). Your money grows tax-deferred, and you pay ordinary income tax on withdrawals in retirement.
- You're in a high tax bracket now (32%+) and expect a lower rate in retirement
- You need the current-year tax deduction to reduce your bill
- You're over 50 and have limited years for Roth tax-free compounding to work
- You expect your retirement income to be substantially lower than your current income
High Earners: The Backdoor Roth Strategy
If your income exceeds Roth IRA limits, you can still get money into a Roth through the backdoor Roth IRA:
- Contribute $7,000 to a Traditional IRA (no income limit on contributions, only on deductibility)
- Immediately convert it to a Roth IRA
- Pay taxes on any gains (minimal if converted quickly)
- Done — you now have Roth money, regardless of your income
This strategy is legal and widely used. Work with a tax professional or CPA if you have existing pre-tax IRA balances, as the "pro-rata rule" can complicate things.
2026 Contribution Limits
- Under age 50: $7,000/year across all IRAs combined
- Age 50 and older: $8,000/year (catch-up contribution of $1,000 extra)
- Contributions can be made until tax filing deadline (April 15, 2027 for 2026)
- You must have earned income equal to or greater than your contribution amount
