Roth vs. Traditional IRA: Which One Fits Your Money Goals

The core difference: when you pay taxes

A traditional IRA lets you deduct contributions from your taxes right now, but you pay income tax on the money when you withdraw it in retirement. A Roth IRA takes the opposite path: you contribute after-tax dollars (no deduction today), and then withdrawals in retirement are tax-free.

That single difference ripples through everything else about how these accounts work. It changes how much you can contribute each year, when you have to start taking money out, who can open one, and what your tax bill looks like decades from now.

Neither is universally "better"—the right choice depends on whether you think your tax rate will be higher or lower in retirement than it is today, and on your income right now.

Key Takeaways

Traditional IRA contributions may reduce your taxable income this year, but withdrawals in retirement are taxed as ordinary income.
Roth IRA contributions use after-tax money, but may have access to withdrawals in retirement—including all growth—are completely tax-free.
You can contribute to a traditional IRA at any age, but you must have earned income and meet income limits to contribute to a Roth.
Traditional IRAs require you to start withdrawing money at age 73 (as of 2023); Roth IRAs have no withdrawal requirement during your lifetime.
If you expect to be in a higher tax bracket in retirement, a Roth may save you more money; if you expect a lower bracket, traditional may be better.

How contributions and deductions work

With a traditional IRA, you can deduct your contribution from your income on your tax return—but only if you meet certain conditions. If you have a workplace retirement plan (like a 401(k)) and your income exceeds a threshold, the deduction phases out or disappears entirely. For 2024, that threshold is $77,000 for single filers and $123,000 for married filing jointly, though these numbers change yearly. If you have no workplace plan, you can deduct the full amount regardless of income.

With a Roth IRA, there is no deduction. You contribute money you have already paid income tax on. However, you can only contribute if your income is below a limit—for 2024, that limit is $161,000 for single filers and $240,000 for married filing jointly. Above those numbers, you cannot contribute directly to a Roth, though some people use a "backdoor Roth" strategy to work around this (converting a traditional IRA to a Roth).

Both account types have the same annual contribution limit: $7,000 for people under 50, and $8,000 for people 50 and older (as of 2024). That limit applies across all IRAs you own—you cannot contribute $7,000 to a traditional IRA and another $7,000 to a Roth in the same year.

Taxes on growth and withdrawals

Money inside either account grows tax-free while it sits there. You do not pay capital gains tax on stock appreciation, dividend income, or interest earned inside the account. The difference shows up when you take the money out.

In a traditional IRA, every dollar you withdraw is taxed as ordinary income at your current tax rate. If you withdraw $50,000 in a year when you are in the 22% tax bracket, you owe roughly $11,000 in federal income tax on that withdrawal (plus state tax if your state has one). This applies to both your original contributions and all the growth.

In a Roth IRA, withdrawals are tax-free if you meet two conditions: the account has been open for at least five tax years, and you are at least 59½ years old (or meet another exception like disability or first-time home purchase). If both conditions are met, you withdraw your contributions and all growth without paying any tax.

Required withdrawals and account access

Traditional IRAs force you to start withdrawing money at age 73 (this changed from age 72 in 2023). The IRS calculates a minimum amount you must withdraw each year based on your age and account balance—these are called required minimum distributions (RMDs). If you do not take the full amount, you owe a penalty of 25% on the shortfall (reduced to 10% if you correct it within two years).

Roth IRAs have no RMD requirement during your lifetime. You can leave the money untouched for as long as you want, which makes them useful if you do not need the money in retirement or want to pass the account to heirs.

Both accounts let you withdraw your contributions (not the growth) at any time without penalty, though a traditional IRA withdrawal is still taxable. Roth IRAs let you withdraw contributions penalty-free and tax-free anytime. Withdrawing growth before 59½ typically triggers a 10% penalty plus income tax, though some exceptions exist—first-time home purchase (up to $10,000 lifetime), education expenses, and a few others.

Income limits and who can open each type

You can open a traditional IRA as long as you have earned income from work, no matter how old you are or how much money you make. There are no income limits. However, the tax deduction phases out if you have a workplace retirement plan and earn above the threshold mentioned earlier.

A Roth IRA requires earned income and has strict income limits. For 2024, single filers earning $161,000 or more cannot contribute directly. Married couples filing jointly cannot contribute if they earn $240,000 or more. These limits change yearly and are indexed to inflation.

If your income exceeds the Roth limit, you have options: contribute to a traditional IRA instead, or use a backdoor Roth (contribute to a traditional IRA, then convert it to a Roth). The backdoor strategy works regardless of income, but it has tax complications if you already own traditional IRAs with pre-tax money.

Which one makes sense for your situation

Choose a traditional IRA if you want to reduce your taxable income this year, expect to be in a lower tax bracket in retirement, or earn too much to contribute to a Roth. It is also simpler if you have a workplace retirement plan and want to keep things straightforward.

Choose a Roth IRA if you expect to be in a higher tax bracket in retirement, want tax-free withdrawals and no RMD requirement, or want maximum flexibility to access your contributions. Roth accounts are also better if you want to leave money to heirs, since they inherit the tax-free growth.

Many people benefit from having both types—contributing to a traditional IRA for the immediate tax break and a Roth for tax-free growth later. The math depends on your current tax rate, expected retirement tax rate, and how long the money will grow.

Conversions and switching between account types

You can convert money from a traditional IRA to a Roth IRA at any time. When you do, you pay income tax on the amount converted in that year. For example, if you convert $30,000 and you are in the 24% tax bracket, you owe roughly $7,200 in federal tax on the conversion.

People often convert when their income is temporarily low (a year they took unpaid leave, retired early, or had a business loss) or when they expect tax rates to rise in the future. There is no income limit on conversions, which is why the backdoor Roth strategy works for high earners.

Conversions are permanent—you cannot undo them. Plan the timing carefully and consider whether you have cash outside the IRA to pay the tax bill, since paying the tax from the IRA itself reduces the amount that gets converted and triggers an early withdrawal penalty if you are under 59½.

Frequently Asked Questions

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

Yes. You can own both types simultaneously, but your total contributions across all IRAs cannot exceed the annual limit ($7,000 or $8,000 depending on age). For example, you could contribute $4,000 to a traditional IRA and $3,000 to a Roth in the same year, but not $7,000 to each.

What happens to my Roth IRA if I die?

Your heirs inherit the account and can withdraw the money tax-free if the account was open for at least five tax years. They must take distributions over their own lifetime (or within ten years, depending on when you died and their relationship to you), but the tax-free growth remains intact. This makes Roths valuable for passing wealth to the next generation.

Can I withdraw from my IRA before retirement without a penalty?

With a Roth, you can withdraw contributions anytime penalty-free. With a traditional IRA, withdrawals before 59½ are taxable and usually subject to a 10% penalty, though exceptions exist for disability, medical expenses, education, and first-time home purchase (up to $10,000). Both accounts allow penalty-free withdrawals for these specific reasons.

What if my income changes and I no longer may have access to for a Roth?

You cannot contribute directly to a Roth if your income exceeds the limit, but you can use a backdoor Roth: contribute to a traditional IRA, then convert it to a Roth. This works at any income level, though it gets complicated if you already own traditional IRAs with pre-tax money. Consult a tax professional before attempting a backdoor conversion.

Which account grows faster, traditional or Roth?

Both grow at the same rate inside the account—the difference is tax treatment, not growth. A Roth may leave you with more money after taxes because withdrawals are tax-free, but that depends on your tax bracket in retirement. The account type itself does not affect how fast your investments grow.
