The answer depends on your income now versus what you expect in retirement

A traditional IRA lets you deduct contributions from your taxes this year, lowering what you owe. You pay taxes later when you withdraw the money in retirement. A Roth IRA takes money after taxes go out, but withdrawals in retirement are tax-free. Neither is universally "better"—the right choice depends on whether you think your tax rate will be higher or lower when you retire than it is today.

If you expect to be in a lower tax bracket in retirement, a traditional IRA usually makes more sense: you save taxes at a higher rate now and pay them at a lower rate later. If you expect to be in the same bracket or a higher one, a Roth typically wins because you lock in today's tax rate and pay nothing later. The catch is that nobody knows future tax rates with certainty, so the choice often comes down to your current situation and what feels safer to you.

Key Takeaways

  • Traditional IRAs reduce your taxable income this year but require you to pay income tax on withdrawals after age 59½, while Roth IRAs take after-tax money now and let you withdraw tax-free later.
  • Your current income and expected retirement income determine which saves you more money overall, but future tax rates are unknowable, so certainty matters too.
  • Income limits restrict who can contribute to a Roth IRA directly, but traditional IRA contributions are available to anyone with earned income, though deductibility phases out at higher incomes.
  • Roth IRAs have no required withdrawals during your lifetime, while traditional IRAs force withdrawals starting at age 73, which can push you into a higher tax bracket.
  • You can convert a traditional IRA to a Roth later, but you pay income tax on the converted amount in that year.

How taxes work differently in each account type

With a traditional IRA, you contribute money before taxes are taken out (or you deduct the contribution on your tax return). The account grows tax-free for decades. When you withdraw money after age 59½, that withdrawal counts as ordinary income and you pay your regular income tax rate on it. If you withdraw before 59½, you typically owe income tax plus a 10 percent penalty, with some exceptions for hardship.

With a Roth IRA, you contribute money that has already been taxed. The account grows tax-free, and when you withdraw after age 59½, you owe nothing—no income tax, no penalty, nothing. You can also withdraw your contributions (not the earnings) at any time without penalty, because you already paid tax on that money. This flexibility is one reason Roths appeal to people who might need access to their savings before retirement.

The long-term math depends on tax brackets. Suppose you earn $70,000 now and expect to earn $50,000 in retirement. You are in a 22 percent federal bracket now and will be in a 12 percent bracket later. A traditional IRA saves you 22 percent in taxes today but costs you only 12 percent in taxes later—a 10 percent gain. A Roth costs you 22 percent today with no tax later, so you lose that 10 percent advantage. Reverse the scenario (higher retirement income) and the Roth wins instead.

Income limits that restrict Roth contributions

You can only contribute to a Roth IRA if your income falls below a certain threshold. For 2024, the limit phases out between $146,000 and $161,000 for single filers and between $230,000 and $240,000 for married couples filing jointly. These numbers change each year. If your income exceeds the limit, you cannot contribute to a Roth directly.

Traditional IRA contributions have no income limit—anyone with earned income can contribute. However, if you have access to a workplace retirement plan (like a 401(k)) and your income exceeds a threshold, the tax deduction for traditional IRA contributions phases out. For 2024, this phase-out begins at $77,000 for single filers with a workplace plan. Again, these thresholds shift annually.

If you earn too much for a direct Roth contribution, you have an option called a backdoor Roth: contribute to a traditional IRA (which has no income limit) and then convert it to a Roth. You pay income tax on any earnings in the traditional account at conversion time, but the strategy works if you have little or no money already sitting in traditional IRAs. This is a real tactic people use, but it requires careful record-keeping and coordination with your tax return.

Required withdrawals and flexibility in retirement

Traditional IRAs force you to start taking withdrawals at age 73. The IRS calculates a minimum amount each year based on your age and account balance, and you must withdraw at least that much or face a 25 percent penalty on the shortfall (reduced to 10 percent if you correct it within two years). These required minimum distributions (RMDs) count as income, which can push you into a higher tax bracket, affect Medicare premiums, or trigger taxes on Social Security benefits.

Roth IRAs have no required withdrawals during your lifetime. You can leave the money untouched for as long as you want, letting it grow tax-free. Your heirs will inherit it tax-free too (though they face different rules for withdrawals). This makes Roths useful if you do not need the money in retirement or want to pass wealth to the next generation.

If you have both types of accounts, RMDs apply only to traditional IRAs and any SEP or SIMPLE IRAs you own. Roth IRAs are excluded. Some people use this to their advantage: they keep a Roth untouched and take RMDs from a traditional IRA, managing their tax bracket more precisely.

Contribution limits and catch-up rules

Both traditional and Roth IRAs share the same annual contribution limit. For 2024, you can contribute up to $7,000 per year if you are under age 50. If you are 50 or older, you can contribute an additional $1,000 as a catch-up contribution, for a total of $8,000. These limits apply across all your IRAs combined—if you have both a traditional and a Roth, your total contributions to both cannot exceed the annual limit.

You must have earned income to contribute. Earned income means wages, salary, self-employment income, or other compensation you received for work. Investment income, Social Security, pensions, and unemployment benefits do not count. If you are married and one spouse does not work, the working spouse can contribute to a spousal IRA in the non-working spouse's name, up to the same limit.

When a traditional IRA makes more sense

Choose a traditional IRA if you are in a high tax bracket now and expect to be in a lower one in retirement. This is common for high earners in their peak earning years who plan to retire and live on less. You also benefit from the immediate tax deduction, which reduces what you owe this year—useful if you want to lower your taxable income or get a larger refund.

A traditional IRA also works well if your income exceeds Roth limits and you cannot or do not want to do a backdoor conversion. You get the tax deduction now (if may be able to access) and defer the tax bill to retirement. If you expect to live a long time and withdraw slowly, you may pay less total tax because you spread withdrawals across many years at lower rates.

Traditional IRAs are also simpler if you have a workplace 401(k) and want to coordinate your retirement savings. Some people max out their 401(k) first (which has a much higher limit: $23,500 for 2024) and then contribute to a traditional IRA for additional tax-deferred growth.

When a Roth IRA makes more sense

Choose a Roth if you are in a lower tax bracket now and expect to be in the same bracket or higher in retirement. This is common for younger workers, people early in their careers, or those with modest current income. You lock in a lower tax rate today and pay nothing later, which is a may provide win if tax rates rise.

A Roth also makes sense if you want flexibility. You can withdraw contributions anytime without penalty, which gives you access to your money if an emergency arises. You also avoid required withdrawals in retirement, so you have full control over when and how much to withdraw. This matters if you do not need the money and want to let it grow for heirs or if you want to manage your tax bracket carefully.

Roths are particularly valuable if you expect to live a long time, because tax-free growth compounds over decades. They are also useful if you think tax rates will rise significantly—locking in today's rate protects you from future increases. And if you have a high income now but expect it to drop (due to job loss, retirement, or career change), a Roth conversion during the low-income year can be a smart move.

Converting between account types

You can convert money from a traditional IRA to a Roth IRA at any time. The conversion counts as a withdrawal from the traditional IRA, so you owe income tax on the amount converted in that tax year. You do not owe the 10 percent early withdrawal penalty, even if you are under 59½, but you do owe the income tax.

Conversions make sense when your income is temporarily low (a year you took unpaid leave, lost a job, or retired early) or when you expect tax rates to rise. You pay tax at a lower rate now and lock in tax-free withdrawals later. Some people do a series of small conversions over several years to spread the tax bill and stay in a lower bracket each year.

The downside is that conversions increase your taxable income in the year you do them, which can trigger higher Medicare premiums, taxes on Social Security, or the net investment income tax. Work with a tax professional if you are considering a conversion, because the timing and amount matter significantly.

Frequently Asked Questions

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

Yes. Your total contributions across all IRAs cannot exceed the annual limit ($7,000 for 2024 if you are under 50), but you can split that between a traditional and a Roth however you want. Many people use both: a traditional IRA for the immediate tax deduction and a Roth for tax-free growth later.

What happens to my IRA if I die before retirement?

Your heirs inherit the account and must take withdrawals based on their relationship to you and the account type. Spouses can roll it into their own IRA. Non-spouse heirs must withdraw the balance within ten years (as of 2023 rules). Roth IRAs are generally better for heirs because withdrawals are tax-free, while traditional IRA withdrawals are taxable income to them.

Can I withdraw from my IRA before age 59½ without a penalty?

Traditional IRAs charge a 10 percent penalty plus income tax on early withdrawals, with exceptions for disability, medical expenses over 7.5 percent of income, and a few other situations. Roth IRAs let you withdraw contributions anytime without penalty, but earnings withdrawals before 59½ face the same penalty and tax unless an exception applies.

Do I have to choose one type and stick with it forever?

No. You can convert a traditional IRA to a Roth, open a Roth after years of traditional contributions, or change your strategy as your situation changes. Your income, tax bracket, and retirement timeline may shift, and your account type can shift with them.

Which type is better if I am self-employed?

Self-employed people can use either a traditional or Roth IRA, but they often benefit more from a SEP IRA or Solo 401(k), which allow much higher contributions. If you do use a traditional or Roth IRA, the choice between them follows the same logic: lower tax bracket now points to Roth, higher bracket now points to traditional.
