A Roth IRA and a traditional IRA are two separate account types with opposite tax rules

No, a Roth is not a traditional IRA—they are two distinct retirement accounts with fundamentally different tax structures. The core difference comes down to when you pay taxes: with a traditional IRA, you may deduct contributions from your taxable income now and pay taxes when you withdraw money in retirement. With a Roth IRA, you contribute money that has already been taxed, and then your withdrawals in retirement are tax-free.

This distinction matters because it changes how much money you actually keep at every stage. A $7,000 contribution to a traditional IRA might reduce your taxes this year, while the same $7,000 to a Roth comes from money you've already paid taxes on. Neither is universally "better"—the right choice depends on whether you expect to be in a higher or lower tax bracket when you retire.

Key Takeaways

  • Traditional IRAs let you deduct contributions now and pay taxes on withdrawals later; Roth IRAs take after-tax money now and give you tax-free withdrawals later.
  • 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 required withdrawals during your lifetime.
  • Income limits restrict who can contribute directly to a Roth, but there are no income limits for traditional IRAs.
  • You can hold both a Roth and a traditional IRA at the same time, but your total contributions across both cannot exceed the annual limit.

How the tax deduction works in a traditional IRA

When you contribute to a traditional IRA, you may be able to deduct the full amount from your taxable income in the year you make the contribution. This deduction lowers your adjusted gross income (AGI), which can reduce the taxes you owe that year. The deduction is only available if you meet certain conditions: you must have earned income, and if you or your spouse are covered by a workplace retirement plan (like a 401(k)), your income must fall below certain thresholds to claim the full deduction.

The money inside the account grows tax-free while it sits there. You do not pay taxes on dividends, interest, or capital gains as they accumulate. But when you withdraw money in retirement, every dollar you take out is taxed as ordinary income at whatever your tax rate is that year. If you withdraw $50,000 from a traditional IRA and you are in the 22% tax bracket, you owe roughly $11,000 in federal income tax on that withdrawal.

How the Roth IRA avoids taxes on withdrawals

A Roth IRA works in reverse. You contribute money that you have already paid income tax on—there is no deduction. The account grows tax-free, just like a traditional IRA. But when you withdraw money in retirement, you owe no federal income tax on any of it, including the growth.

This tax-free withdrawal feature is the defining advantage of a Roth. If you contribute $7,000 and it grows to $25,000 over 30 years, you can withdraw the full $25,000 without owing taxes on the $18,000 in gains. For a traditional IRA, that same $18,000 in growth would be taxed as ordinary income when you withdraw it.

There is one catch: you must have held the Roth for at least five years and be age 59½ to withdraw earnings tax-free. If you withdraw earnings before that, you pay income tax on them plus a 10% penalty. You can always withdraw your own contributions penalty-free at any age, but the earnings are restricted.

Income limits and who can contribute to each type

Traditional IRAs have no income limits. Anyone with earned income can contribute, regardless of how much money they make. If you earn $200,000 or $2 million, you can still put money into a traditional IRA.

Roth IRAs have income phase-out ranges that change each year. For 2024, if you file as single, you can contribute the full amount if your modified adjusted gross income (MAGI) is below $146,000. The ability to contribute phases out between $146,000 and $161,000, and you cannot contribute at all above $161,000. If you are married filing jointly, the ranges are higher. These limits exist because Congress wanted Roth accounts to benefit middle-income savers, not high earners.

If your income exceeds the Roth limit, you have an alternative called a backdoor Roth. You contribute to a traditional IRA (which has no income limit) and then convert it to a Roth. This is legal but comes with tax complications if you already have other traditional IRAs, so consult a tax professional before attempting it.

Required withdrawals and account flexibility

Traditional IRAs require you to start taking withdrawals at age 73. The IRS calculates a minimum amount based on your age and account balance, and you must withdraw at least that much each year. These are called required minimum distributions (RMDs). If you do not take the full RMD, you face a 25% penalty on the amount you should have withdrawn (reduced to 10% if you correct it within two years).

Roth IRAs have no required minimum distributions during your lifetime. You can leave the money untouched for as long as you want, and your heirs inherit it tax-free. This makes a Roth more flexible if you do not need the money in retirement or want to pass wealth to the next generation.

Contribution limits apply across both account types

The IRS sets an annual contribution limit that covers both traditional and Roth IRAs combined. For 2024, you can contribute up to $7,000 total across both accounts if you are under 50, or $8,000 if you are 50 or older. You cannot contribute $7,000 to a traditional IRA and another $7,000 to a Roth in the same year—your total across both is capped at $7,000.

This means you can split contributions between the two types if you want. You might put $4,000 in a traditional IRA for the tax deduction and $3,000 in a Roth for tax-free growth. The flexibility is yours, but the total cannot exceed the annual limit.

Which one makes sense for your situation

Choose a traditional IRA if you want to reduce your taxable income this year and expect to be in a lower tax bracket in retirement. This is common for high earners who plan to retire and have less income, or for people who want to lower their income to stay below certain thresholds (like for Medicare premiums or Roth conversion limits).

Choose a Roth if you expect to be in the same or higher tax bracket in retirement, or if you want maximum flexibility and tax-free growth. Roth accounts are especially valuable for younger savers who have decades of tax-free compounding ahead and likely have many years of earning potential left.

Many people benefit from having both. You might use a traditional IRA to reduce taxes now while you are working, and a Roth to build tax-free wealth for later. The two accounts complement each other rather than compete.

Frequently Asked Questions

Can I convert a traditional IRA to a Roth?

Yes. You can convert all or part of a traditional IRA to a Roth at any time. The amount you convert is treated as taxable income in the year of conversion, so you will owe taxes on it. This strategy makes sense if you expect tax rates to rise or if you have a low-income year and can absorb the tax hit.

What happens to my IRA if I die?

Your beneficiary inherits the account. With a traditional IRA, they must pay income tax on withdrawals. With a Roth, withdrawals are tax-free. Either way, they have options for how quickly to withdraw the money, depending on their relationship to you and current IRS rules.

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

Yes, you can hold both simultaneously. Your combined contributions across both accounts cannot exceed the annual limit, but you can split your contributions however you want between them.

Do I pay taxes twice with a Roth—once when I earn the money and again when I withdraw it?

No. You pay income tax on the money once, when you earn it. The contribution itself comes from after-tax dollars, but the withdrawal is tax-free. You do not pay tax twice.

What if I need to withdraw money from my Roth before retirement?

You can withdraw your contributions anytime without penalty or taxes. If you withdraw earnings before age 59½ and before holding the account five years, you pay income tax on the earnings plus a 10% penalty. Some exceptions exist for first-time home purchases, disability, or medical expenses.
