The choice depends on whether you want a tax break now or in retirement

A traditional IRA lets you deduct contributions from your taxes this year, lowering what you owe. A Roth IRA takes after-tax money now but lets you withdraw it tax-free later. Neither is universally "better"—the right one depends on your current tax bracket, how much you expect to earn in retirement, and whether you want flexibility before you turn 59½.

If you are in a high tax bracket now and expect to be in a lower one in retirement, traditional usually wins. If you are in a low bracket now and expect to be higher later—or you simply want tax-assistance programs you can touch without penalty—Roth usually makes more sense. The catch is that income limits restrict who can contribute to a Roth, and traditional IRAs have required withdrawals starting at age 73, while Roths do not.

Key Takeaways

  • Traditional IRA contributions reduce your taxable income this year; Roth contributions do not, but withdrawals in retirement are tax-free.
  • You can only contribute to a Roth if your income is below a certain threshold, which changes yearly and depends on filing status.
  • Traditional IRAs require you to start taking withdrawals at age 73; Roths have no required withdrawals during your lifetime.
  • If you change your mind, you can convert a traditional IRA to a Roth, but you will owe taxes on the amount converted that year.
  • Roth withdrawals before age 59½ are penalty-free if the account has been open at least five years, but traditional withdrawals before that age usually trigger a 10% penalty plus income tax.

When a traditional IRA makes sense

Choose traditional if you want to lower your tax bill right now. When you contribute, that money comes off your adjusted gross income, which means you pay federal income tax on less money. If you are self-employed or in a high-income year, this deduction can be substantial.

Traditional also works well if you expect your tax bracket to drop in retirement. Many people earn less after they stop working, which means withdrawals are taxed at a lower rate than the contributions would have been. You are essentially deferring taxes to a time when the tax rate works in your favor.

One more scenario: if your income is too high for a Roth contribution, traditional is your only direct option. There is no income limit on traditional IRA contributions, though the deduction itself phases out if you or your spouse have a workplace retirement plan and earn above a certain amount.

When a Roth IRA makes sense

Choose Roth if you want tax-assistance programs in retirement and you are comfortable paying taxes now. Because contributions go in after-tax, you never pay federal income tax on withdrawals—not on the original money and not on the growth. Over decades, that tax-free compounding can be worth far more than a deduction today.

Roth is especially strong if you are young, early in your career, or in a low tax bracket. Your contributions are smaller relative to your future earnings, so the tax you pay now is likely less than the tax you would pay on a much larger withdrawal later. It is also the right choice if you expect your income to rise significantly or if you think tax rates will be higher in the future.

Roth also gives you flexibility. You can withdraw your contributions (not the earnings) at any time without penalty or tax, which makes it function partly as an emergency fund. And because there are no required withdrawals, you can let the money sit and grow as long as you want, or leave it to heirs tax-free.

Income limits and contribution rules

Roth contributions are limited by income. For 2024, if you file as single, you can contribute the full amount only if your modified adjusted gross income is below $146,000. The ability to contribute phases out between $146,000 and $161,000. If you are married filing jointly, the phase-out range is $230,000 to $240,000. These numbers change yearly.

If your income exceeds the Roth limit, you have two options: contribute to a traditional IRA instead, or use the "backdoor Roth" strategy. A backdoor Roth means you contribute to a traditional IRA with after-tax money, then immediately convert it to a Roth. You pay no tax on the conversion because the money was never deductible. This is legal but requires careful record-keeping, especially if you have other traditional IRAs.

Traditional IRAs have no income limit on contributions, but the deduction phases out if you have a workplace 401(k) or similar plan. For 2024, if you are single with a workplace plan, the deduction phases out between $77,000 and $87,000 of income. If married filing jointly and your spouse has a plan, it phases out between $123,000 and $133,000. Again, these thresholds shift yearly.

Taxes and withdrawals: the long-term picture

With a traditional IRA, every dollar you withdraw in retirement is taxed as ordinary income. If you withdraw $50,000 in a year when you are in the 22% tax bracket, you owe $11,000 in federal tax on that withdrawal alone. This matters because large withdrawals can push you into a higher bracket or trigger taxes on Social Security benefits.

With a Roth, withdrawals are never taxed. You can withdraw $50,000 and owe nothing federally. This also means Roth withdrawals do not affect the taxation of your Social Security or trigger the Medicare income-related premium surcharge, which is based on modified adjusted gross income. For people who want to control their tax situation in retirement, this is a major advantage.

The trade-off is timing. Traditional gives you a tax break immediately; Roth makes you wait. If you need the deduction now to lower your current tax bill, traditional wins. If you can afford to pay taxes now and want to lock in tax-free growth, Roth wins.

Required withdrawals and flexibility

Traditional IRAs require you to take withdrawals starting the year you turn 73. The IRS calculates a minimum amount based on your age and account balance, and you must withdraw at least that much or face a 25% penalty on the shortfall (10% if you miss the deadline by more than two years). These required minimum distributions, or RMDs, force you to take taxable income whether you need it or not.

Roth IRAs have no required withdrawals during your lifetime. You can let the money sit untouched for decades if you do not need it, and your heirs inherit it tax-free. This makes Roth better if you want maximum control over when and how much you withdraw, or if you plan to leave money to the next generation.

One exception: if you inherit a Roth IRA from someone other than a spouse, you must withdraw the entire balance within ten years under current rules. But those withdrawals are still tax-free, which is a significant advantage over inheriting a traditional IRA.

Early withdrawal rules and penalties

If you need money before age 59½, Roth is more forgiving. You can withdraw your contributions anytime, tax-free and penalty-free. If you contributed $5,000 a year for ten years, you can pull out $50,000 whenever you want. You can only withdraw earnings before 59½ if you meet an exception—disability, medical expenses above 7.5% of adjusted gross income, or a few others—or if the account has been open at least five years.

Traditional IRAs penalize early withdrawal. Any withdrawal before 59½ is subject to a 10% penalty plus income tax on the full amount. There are exceptions—substantially equal periodic payments, disability, medical expenses—but they are narrow and require careful calculation. If you withdraw $10,000 early from a traditional IRA and are in the 22% tax bracket, you owe $2,200 in tax plus $1,000 in penalty, leaving you $6,800.

This flexibility makes Roth attractive if you are not certain you will not need the money, or if you want a backup source of funds without the penalty cost.

Converting between account types

You can convert a traditional IRA to a Roth at any time, regardless of age or income. The conversion is treated as a withdrawal from the traditional IRA and a contribution to the Roth. You owe income tax on the amount converted that year, but once it is in the Roth, it grows tax-free forever.

Conversions make sense if you expect tax rates to rise, if you have a low-income year, or if you want to move money into a tax-free account before required withdrawals begin. The downside is the immediate tax bill. If you convert $100,000 and are in the 24% bracket, you owe $24,000 in federal tax that year. You must have money outside the IRA to pay this tax, or the amount owed reduces what actually moves to the Roth.

Some people do a series of small conversions over several years to spread the tax impact. Others wait for a year when income is unusually low—between jobs, for example—to convert a larger amount at a lower rate.

Frequently Asked Questions

Can I have both a traditional and Roth IRA at the same time?

Yes. Your total contribution across all IRAs cannot exceed the annual limit—$7,000 for 2024 if you are under 50, or $8,000 if you are 50 or older—but you can split that between accounts however you want. Some people keep both to hedge their tax bets or to use traditional for a deduction and Roth for flexibility.

What happens to my Roth IRA if I die?

Your heirs inherit it tax-free, but they must withdraw the balance within ten years under current rules. The withdrawals themselves are not taxed, which is a major advantage over inheriting a traditional IRA. A spouse can treat the inherited Roth as their own and avoid the ten-year rule.

Can I deduct traditional IRA contributions if I do not have a job?

Only if you have earned income—wages, self-employment income, or taxable alimony. You cannot contribute based on investment income or Social Security. The amount you can contribute is limited to your earned income that year or the annual limit, whichever is smaller.

Does contributing to a traditional IRA reduce my taxable income if I take the standard deduction?

Yes. The traditional IRA deduction is separate from the standard deduction. You can take both. However, if you have a workplace retirement plan and your income is above the phase-out range, the deduction may be reduced or eliminated.

What is the five-year rule for Roth IRAs?

To withdraw earnings tax-free, your Roth account must have been open for at least five tax years. Contributions can always come out tax-free regardless of age or how long the account has been open. The five-year clock resets if you convert a traditional IRA to a Roth, meaning you must wait five years from the conversion date to withdraw those converted funds penalty-free before age 59½.
