The choice depends on your tax situation now versus later

Neither is objectively better—the right choice depends on whether you expect to pay more in taxes this year or in retirement. A traditional IRA lets you deduct contributions from your current income, lowering your taxes now. A Roth IRA takes contributions after tax, but then you pay no tax on withdrawals in retirement. The trade-off is simple: pay taxes on the money going in, or pay taxes on the money coming out.

If you are in a high tax bracket now and expect to be in a lower one in retirement, traditional makes sense. If you are in a low bracket now and expect to be higher later—or you simply want to lock in your current tax rate—Roth makes sense. If you are unsure, Roth is often the safer choice for younger workers, because you have decades for tax-free growth and you avoid the guesswork about future tax rates.

Key Takeaways

  • Traditional IRA contributions reduce your taxable income this year; Roth contributions do not, but withdrawals in retirement are tax-free.
  • You must have earned income to contribute to either type, and contribution limits are the same for both ($7,000 per year for 2024, or $8,000 if you are 50 or older).
  • Traditional IRAs require you to start taking withdrawals at age 73; Roth IRAs have no withdrawal requirement during your lifetime.
  • Roth contributions can be withdrawn anytime without penalty; traditional IRA withdrawals before 59½ usually trigger a 10% penalty plus income tax.
  • Income limits apply to Roth contributions but not traditional, though traditional contributions may not be tax-deductible if you have a workplace retirement plan.

How taxes work in each account

In a traditional IRA, you deduct your contribution on your tax return for that year. If you contribute $7,000, your taxable income drops by $7,000. That means you pay less federal income tax this year. The money grows tax-free inside the account. When you withdraw it in retirement, every dollar is taxed as ordinary income at whatever your tax rate is then.

In a Roth IRA, you contribute money you have already paid income tax on. You get no deduction this year. The money grows tax-free inside the account, just like a traditional IRA. When you withdraw it in retirement, you owe nothing—not on the contributions, not on the growth. This is the core difference: traditional taxes you on the way out, Roth taxes you on the way in.

The math works out the same if tax rates never change. But tax rates do change. If federal income tax rates are higher when you retire than they are now, Roth wins. If rates are lower, traditional wins. Most people cannot predict this accurately, which is why the choice often comes down to your gut feeling about the future.

Income limits and workplace plan rules

You can contribute to a traditional IRA no matter how much money you make. But if you have access to a workplace retirement plan—a 401(k), 403(b), or similar—and your income is above a certain threshold, you cannot deduct your traditional IRA contribution. For 2024, that threshold is $77,000 for single filers and $123,000 for married filing jointly (these numbers change yearly). Above those limits, your contribution still goes in, but you get no tax break.

Roth IRAs have income limits that phase out your ability to contribute at all. For 2024, single filers cannot contribute if their income exceeds $161,000; married filers cannot if income exceeds $240,000. If your income is above these limits, you cannot use a Roth IRA directly. Some people use a "backdoor Roth" strategy to work around this, but that involves more steps and tax complexity.

If you do not have a workplace plan, you can deduct traditional IRA contributions regardless of income. This is one reason traditional IRAs remain popular for self-employed people and those without employer-sponsored retirement savings.

Withdrawal rules and penalties

Traditional IRA withdrawals before age 59½ are subject to a 10% penalty plus income tax on the full amount withdrawn. There are narrow exceptions—disability, medical expenses above 7.5% of adjusted gross income, first-time home purchase (up to $10,000 lifetime)—but they are specific and hard to meet. Once you turn 73, you must begin taking withdrawals whether you need the money or not. These are called required minimum distributions, or RMDs, and the IRS calculates how much based on your age and account balance.

Roth IRAs are more flexible. You can withdraw your contributions (not the earnings) anytime, penalty-free and tax-free. You can also withdraw earnings penalty-free if you are 59½ and the account has been open at least five years. Roth IRAs have no RMD requirement during your lifetime, which means you can leave the money untouched and let it grow, or withdraw only what you need. This flexibility is valuable if you do not need the money immediately or if you want to pass the account to heirs.

The five-year rule matters: even if you are 59½, you cannot withdraw Roth earnings tax-free unless the account itself has existed for at least five years. This is a common trap for people who convert a traditional IRA to a Roth late in life.

Which choice makes sense for different situations

Choose traditional if you are in a high tax bracket now and expect to be in a lower one in retirement, or if you need the tax deduction this year to lower your current tax bill. This is common for high earners, self-employed people with lumpy income, or anyone who wants immediate tax relief. It is also the only option if your income exceeds Roth limits and you do not have access to a workplace plan.

Choose Roth if you are early in your career and in a low tax bracket, if you expect your income and tax bracket to rise over time, or if you want the certainty of knowing you will owe no tax in retirement. Roth is also better if you want maximum flexibility—the ability to withdraw contributions, no forced withdrawals, and the option to pass tax-assistance programs to heirs. Younger workers often benefit most from Roth because they have the longest time for tax-free compounding.

If you are unsure, Roth is often the safer default for people under 50, because tax rates are historically low and you lock in that rate for decades. For people closer to retirement, traditional may make more sense if you need the current-year tax deduction and you expect to be in a lower bracket once you stop working.

Contribution limits and catch-up rules

Both traditional and Roth IRAs have the same annual contribution limit: $7,000 for 2024 (this amount changes yearly based on inflation). If you are 50 or older, you can contribute an additional $1,000 per year as a "catch-up" contribution, for a total of $8,000. You can only contribute money you actually earned that year—you cannot contribute more than your total income.

You can split your contribution between traditional and Roth in the same year, but your combined contributions cannot exceed the annual limit. For example, you could contribute $3,500 to a traditional IRA and $3,500 to a Roth IRA in the same year, but not $7,000 to each. If you have a workplace retirement plan, that has its own separate limit and does not count against your IRA limit.

How to decide: a simple framework

Start with income limits. If your income exceeds Roth limits and you have no workplace plan, traditional is your only option. If you have a workplace plan and your income exceeds the traditional deduction threshold, Roth may be your only option (unless you use a backdoor strategy).

If both are available to you, ask yourself: Am I in a higher tax bracket now than I expect to be in retirement? If yes, traditional wins. If no, or if you are unsure, Roth usually wins. Then consider flexibility: Do I want the option to withdraw money before 59½ without penalty? Do I want to avoid forced withdrawals? Do I want to pass tax-assistance programs to heirs? If you answered yes to any of these, Roth has the advantage.

Finally, consider your timeline. If you are more than 20 years from retirement, Roth's tax-free growth has more time to compound, which often makes it the better choice. If you are within 10 years of retirement, the tax deduction from traditional may matter more to your current finances.

Frequently Asked Questions

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

Yes. You can own both accounts simultaneously, and you can contribute to both in the same year. Your combined contributions to both accounts cannot exceed the annual limit ($7,000 for 2024). Many people use both strategically—a traditional IRA for the current-year tax deduction and a Roth for tax-free future growth.

What happens if I change jobs and have a 401(k) from my old employer?

You can roll the 401(k) into a traditional IRA without tax consequences. This is called a direct rollover. If you roll it into a Roth IRA instead, you will owe income tax on the full amount in that year. Rolling into a traditional IRA is simpler; rolling into Roth makes sense only if you expect much higher tax rates later.

Can I convert a traditional IRA to a Roth?

Yes, but you pay income tax on the full amount converted in that year. This is called a Roth conversion. It makes sense if you expect tax rates to be higher in retirement, or if you have a low-income year and can convert at a lower tax cost. The five-year rule applies: you must wait five years before withdrawing the converted amount penalty-free.

What if I withdraw from my Roth before age 59½?

You can withdraw your contributions anytime without penalty or tax. You can withdraw earnings only if you meet an exception (disability, first-time home purchase up to $10,000, etc.) or if you are 59½ and the account is at least five years old. Otherwise, earnings withdrawals trigger a 10% penalty plus income tax.

Do I have to take money out of my Roth in retirement?

No. Roth IRAs have no required minimum distributions during your lifetime. You can leave the money untouched for as long as you want. This is one major advantage over traditional IRAs, where you must begin withdrawals at 73.
