Traditional IRA vs. Roth IRA: Choosing the Right Account for Your Retirement Years

How each account works

A traditional IRA lets you contribute pre-tax or after-tax dollars, depending on your income and workplace plan status. When you contribute pre-tax dollars, the IRS allows a deduction on your federal return, lowering your taxable income for that year. The account grows tax-deferred, meaning no tax is owed on dividends, interest, or capital gains until you take money out. Withdrawals in retirement are taxed as ordinary income, and the IRS requires you to begin taking required minimum distributions (RMDs) starting at age 73 under current rules.

A Roth IRA works the opposite way. Contributions are made with after-tax dollars, so there is no upfront deduction. In exchange, qualified withdrawals, including all investment growth, are completely free of federal income tax. A qualified withdrawal generally requires the account to be at least five years old and the owner to be 59.5 or older. Roth IRAs have no RMDs during the original owner's lifetime, which gives more control over the timing and size of distributions.

For 2024, the IRS set the combined contribution limit for traditional and Roth IRAs at $7,000 per year, with a $1,000 catch-up contribution allowed for those age 50 and older. That limit applies across all IRAs you hold; you cannot contribute $7,000 to each if you have both types. Consult the IRS website for the most current figures, as limits are subject to periodic adjustment.

Tax rates: the central question

The decision between these two accounts ultimately comes down to one comparison: your tax rate now versus your expected tax rate when you withdraw the money. If your rate will be lower in retirement, a traditional IRA's upfront deduction gives you more after-tax value over time. If your rate will be higher, or even the same, a Roth IRA's tax-free withdrawals produce a better outcome.

Many middle-aged workers assume their tax rate will drop in retirement because their salary disappears. That is sometimes true, but not always. Social Security benefits can be partially taxable, RMDs from traditional IRAs and 401(k)s add taxable income, and future tax law changes are unpredictable. Holding both account types, sometimes called tax diversification, allows you to draw from whichever source is more favorable in a given year.

Income limits and deductibility rules

Roth IRA eligibility phases out at higher incomes. For 2024, the phase-out range for single filers begins at $146,000 and ends at $161,000. For married couples filing jointly, it runs from $230,000 to $240,000. Above those ceilings, direct Roth IRA contributions are not permitted, though a strategy known as a backdoor Roth conversion exists for higher-income earners. That strategy involves tax complexity, and a tax professional should evaluate whether it fits your situation.

Traditional IRA contributions are always allowed regardless of income, but the deductibility of those contributions depends on whether you or your spouse participates in a workplace retirement plan. If neither of you has access to a workplace plan, contributions are fully deductible at any income level. If a workplace plan is available, the deduction phases out across IRS-defined income ranges. Non-deductible traditional IRA contributions are still permitted, though the tax benefit is limited and record-keeping becomes more complex.

Withdrawal rules and early access

Traditional IRA withdrawals before age 59.5 generally trigger a 10% early withdrawal penalty on top of ordinary income tax, with narrow exceptions for disability, first-home purchases (up to $10,000 lifetime), substantially equal periodic payments, and a handful of other IRS-defined circumstances.

Roth IRAs treat contributions and earnings differently. Because contributions were already taxed, you can withdraw the amount you contributed at any time, at any age, without tax or penalty. Earnings, however, must satisfy the five-year rule and the age 59.5 requirement to be withdrawn tax-free. This structure gives the Roth IRA a liquidity edge for people who may need to access funds before full retirement age, though using retirement accounts as an emergency source is generally not advisable given the long-term compounding cost.
