How Each Account Is Taxed — The Core Difference
The fundamental distinction between a Roth IRA and a Traditional IRA comes down to when your money is taxed. Understanding this single concept frames every other comparison.
With a Traditional IRA, you contribute pre-tax dollars (assuming you qualify for the deduction). That contribution reduces your taxable income in the year you make it. When you withdraw the money in retirement, those distributions are taxed as ordinary income — federal, and potentially state, depending on where you live.
With a Roth IRA, contributions are made with money you've already paid income tax on. In return, qualified withdrawals — including all investment growth — are completely tax-free in retirement, provided you're at least 59½ and the account has been open for at least five years.
This trade-off is the lens through which every other feature of these accounts should be evaluated. See our guide to saving versus investing for broader context on building a long-term financial strategy.
| Criterion | Roth IRA | Traditional IRA |
|---|---|---|
| Tax treatment of contributions | After-tax (no deduction) | Pre-tax (may be deductible) |
| Tax treatment of withdrawals | Tax-free (if qualified) | Taxed as ordinary income |
| 2024 contribution limit | $7,000 ($8,000 if 50+) | $7,000 ($8,000 if 50+) |
| Income limits to contribute | Yes — phases out at higher incomes | No — but deduction may be limited |
| Required minimum distributions | None during owner's lifetime | Required starting at age 73 |
| Early withdrawal of contributions | Permitted anytime, no penalty | 10% penalty + taxes before 59½ |
| Best tax scenario | Expect higher tax rate in retirement | Expect lower tax rate in retirement |
Contribution Limits, Income Rules, and Eligibility
For 2024, the IRS sets the combined annual contribution limit for IRAs at $7,000, or $8,000 if you're age 50 or older (the additional $1,000 is a catch-up contribution). This limit applies across all your IRAs combined — not per account.
$7,000
2024 IRA annual contribution limit
The IRS sets this combined limit across all traditional and Roth IRAs; those aged 50+ may contribute up to $8,000.
Age 73
Traditional IRA RMD start age
The SECURE 2.0 Act raised the required minimum distribution start age to 73 for those who turn 72 after December 31, 2022.
$161,000
2024 Roth IRA phase-out ceiling (single filers)
Single filers with MAGI above $161,000 are ineligible for direct Roth IRA contributions in 2024, per IRS guidelines.
Roth IRA income limits: Your ability to contribute directly to a Roth IRA phases out above certain modified adjusted gross income (MAGI) thresholds. For 2024, the phase-out range is $146,000–$161,000 for single filers and $230,000–$240,000 for married filing jointly. Above these ceilings, direct Roth contributions are not permitted.
Traditional IRA deductibility limits: Anyone with earned income can contribute to a Traditional IRA regardless of income. However, the ability to deduct that contribution phases out if you or your spouse participate in a workplace retirement plan and your income exceeds IRS thresholds. Non-deductible contributions to a Traditional IRA are still permitted but require tracking via IRS Form 8606 to avoid double taxation later.
Withdrawals, Penalties, and Required Minimum Distributions
Withdrawal rules differ meaningfully between the two account types and can affect long-term financial planning significantly.
Traditional IRA: Withdrawals before age 59½ are generally subject to a 10% early withdrawal penalty plus ordinary income taxes, with limited exceptions (first-time home purchase, certain medical expenses, and others defined by the IRS). Starting at age 73, account holders must take required minimum distributions (RMDs) — mandatory annual withdrawals calculated by the IRS — whether they need the money or not.
Roth IRA: Because contributions were already taxed, you can withdraw your contributions (not earnings) at any time, tax- and penalty-free. Earnings are subject to the 10% penalty if withdrawn early, but the same exceptions apply. Crucially, Roth IRAs have no RMDs during the owner's lifetime, allowing the account to continue growing tax-free for as long as you choose.
The Five-Year Rule for Roth Withdrawals
To take tax-free withdrawals of earnings from a Roth IRA, the account must have been open for at least five tax years, and you must be at least 59½. This clock starts on January 1 of the first year you make any Roth IRA contribution. Opening an account early — even with a small contribution — starts the clock running, which can be advantageous for younger savers.
