Key Takeaways
Option A
Traditional IRA
The tax break now, pay later approach.
Best for: Savers who expect to be in a lower tax bracket in retirement than they are today.
Option B
Roth IRA
The pay now, tax-free later approach.
Best for: Younger earners or those who expect their tax rate to rise over time.
If you're early in your career with a relatively low income
Roth IRA
Paying taxes now at a lower rate and locking in tax-free growth makes the Roth particularly powerful when you have decades of compounding ahead.
If you're in your peak earning years and want to reduce your taxable income today
Traditional IRA
A deductible Traditional IRA contribution lowers your adjusted gross income now, which can be especially valuable when you're in a higher tax bracket.
If you want maximum flexibility and no required distributions in retirement
Roth IRA
Roth IRAs impose no required minimum distributions during the owner's lifetime, giving you more control over when and how you access your funds.
If your income exceeds the Roth IRA eligibility threshold
Traditional IRA
High earners above the Roth income phase-out range may not contribute directly to a Roth IRA, making the Traditional IRA the straightforward option.
How Each Account Handles Taxes
The fundamental difference between a Traditional IRA and a Roth IRA comes down to when the IRS takes its cut. With a Traditional IRA, you contribute pre-tax (or deductible) dollars, reducing your taxable income in the year you contribute. Those funds grow tax-deferred, meaning you pay no taxes on gains until you make withdrawals — at which point distributions are taxed as ordinary income.
A Roth IRA works in reverse. Contributions are made with after-tax dollars, so there's no upfront deduction. However, your money grows tax-free, and qualified withdrawals in retirement are entirely tax-free — including all the gains accumulated over decades.
For anyone new to retirement accounts, this distinction is worth sitting with. It's not about which account earns more money inside — both can hold the same investments. It's purely about tax timing. See our overview of tax-advantaged accounts for broader context on how IRAs fit alongside 401(k)s and other vehicles.
| Criterion | Traditional IRA | Roth IRA |
|---|---|---|
| Tax treatment of contributions | Potentially tax-deductible | After-tax (no deduction) |
| Tax treatment of withdrawals | Taxed as ordinary income | Tax-free (if qualified) |
| Income limits to contribute | None (deductibility may phase out) | Yes — phases out at higher incomes |
| Required minimum distributions | Yes, starting at age 73 | No RMDs during owner's lifetime |
| Early withdrawal of contributions | Taxed + possible 10% penalty | Contributions withdrawable anytime |
| Best if you expect future tax rate to be... | Lower than today | Higher than today |
Eligibility Rules and Contribution Limits
Both account types share the same annual contribution limit — a figure the IRS adjusts periodically for inflation. However, eligibility rules differ in important ways.
Traditional IRA: Anyone with earned income can contribute, regardless of how much they earn. The catch is deductibility: if you or your spouse are covered by a workplace retirement plan, your ability to deduct contributions phases out above certain income thresholds.
Roth IRA: Contribution eligibility itself phases out at higher income levels. Above the IRS-set thresholds (which vary by filing status), you cannot contribute to a Roth IRA directly. Note that the so-called "backdoor Roth" strategy exists, but it involves specific steps and tax implications — consulting a qualified financial professional is advisable before pursuing it.

Age 73
Age Traditional IRA RMDs must begin
The SECURE 2.0 Act, signed into law in late 2022, raised the required minimum distribution starting age from 72 to 73 for most account holders.

Withdrawals, Required Distributions, and Flexibility
Both IRA types penalize early withdrawals — generally a 10% penalty plus applicable taxes if you pull money out before age 59½, with some exceptions. Beyond that baseline, the rules diverge.
Traditional IRAs require you to begin taking required minimum distributions (RMDs) starting at age 73, under current law. The IRS mandates these withdrawals to eventually collect deferred taxes. RMDs are calculated based on your account balance and life expectancy tables.
Roth IRAs have no RMDs during the account owner's lifetime. This makes the Roth particularly useful for estate planning — unused funds can continue growing and be passed to heirs (who will have their own distribution rules to follow).
One additional Roth advantage: because you already paid taxes on contributions, you can withdraw your contributions (not earnings) at any time without penalty. This gives Roth holders a degree of flexibility that Traditional IRA holders don't have in the same way.
