IRA vs. Roth IRA: How the Tax Treatment and Rules Differ

The core difference: when you pay taxes

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

The choice between them hinges on whether you think your tax rate will be higher or lower in retirement than it is now. If you expect to be in a lower tax bracket later, a traditional IRA saves you money. If you expect to be in a higher bracket—or simply want to lock in your current tax rate—a Roth IRA is the better bet.

Both accounts grow tax-free while the money sits inside them. The difference is only in when the tax bill arrives: now (Roth) or later (traditional).

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, so you get no deduction now, but all withdrawals and growth come out tax-free in retirement.
Income limits restrict who can contribute to a Roth IRA directly, while traditional IRA contributions are available to anyone with earned income, though the deduction phases out at higher incomes if you have a workplace retirement plan.
Traditional IRAs require you to start taking withdrawals at age 73, but Roth IRAs have no withdrawal requirement during your lifetime.
Roth IRAs allow you to withdraw your contributions (not earnings) at any time without penalty, while traditional IRAs charge a 10% penalty on early withdrawals before age 59½.

How income limits affect your choice

You can contribute to a traditional IRA regardless of how much you earn, but the tax deduction phases out if you have access to a workplace retirement plan like a 401(k) and your income exceeds a certain threshold. For 2024, that phase-out begins at $77,000 for single filers and $123,000 for married couples filing jointly (these numbers change each year).

Roth IRA contributions have stricter income limits. For 2024, the ability to contribute directly phases out between $146,000 and $161,000 for single filers, and between $230,000 and $240,000 for married couples filing jointly. If your income exceeds the upper limit, you cannot contribute to a Roth IRA directly—though you may be able to use a "backdoor Roth" strategy, which involves contributing to a traditional IRA and then converting it to a Roth.

Check your income against the current year's limits before deciding which account to open. The IRS publishes updated limits each January.

Required withdrawals and access to your money

Traditional IRAs force you to start taking withdrawals at age 73, whether you need the money or not. These are called required minimum distributions (RMDs), and the IRS calculates the amount based on your age and account balance. Missing an RMD triggers a 25% penalty on the amount you should have withdrawn (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 live, which makes them useful if you want to pass the account to heirs or simply do not need the income yet.

Both accounts penalize withdrawals before age 59½, but Roth IRAs offer a unique exception: you can withdraw your contributions (the money you put in) at any time without penalty or tax. You cannot touch the earnings without penalty until 59½, but the ability to access your contributions penalty-free makes a Roth IRA function partly as an emergency fund.

Contribution limits and catch-up contributions

Both traditional and Roth IRAs share the same annual contribution limit: $7,000 for 2024 (or $8,000 if you are age 50 or older, thanks to catch-up contributions). This limit applies to your combined contributions across all IRAs you own—you cannot put $7,000 in a traditional IRA and another $7,000 in a Roth in the same year.

The catch-up provision is valuable if you are behind on retirement savings. At age 50, you can add an extra $1,000 per year to either account type, and this extra amount does not count against the income limits for Roth contributions.

Tax implications for conversions and inherited accounts

You can convert money from a traditional IRA to a Roth IRA at any time, but the conversion is a taxable event. You owe income tax on the amount converted in the year you do it. This is why the backdoor Roth strategy works: you contribute to a traditional IRA (no tax deduction if your income is too high), then immediately convert it to a Roth (paying tax on a small amount), and end up with Roth money despite the income limit.

If you inherit an IRA from someone other than a spouse, the rules changed in 2023. You must now withdraw the entire inherited account within 10 years, though you do not have to take annual withdrawals. The tax treatment depends on whether the original account was traditional or Roth: inherited traditional IRA withdrawals are taxed as income, while inherited Roth withdrawals are tax-free (as long as the original owner had owned the account for at least five years).

Which account 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 have income too high to contribute to a Roth. It is also useful if you have a lot of pre-tax money already in retirement accounts and want to keep things simple.

Choose a Roth IRA if your income is within the limits, you expect tax rates to rise, you want tax-free withdrawals in retirement, or you value the flexibility of accessing contributions early. A Roth is also the better choice if you do not need the money in retirement and want to pass a tax-free account to heirs.

Many people benefit from having both: a traditional IRA for the immediate tax deduction and a Roth for tax-free growth and flexibility. There is no rule against owning both accounts simultaneously, as long as your combined contributions do not exceed the annual limit.

Frequently Asked Questions

Can I contribute to both a traditional IRA and a Roth IRA in the same year?

Yes, but your combined contributions to all IRAs cannot exceed $7,000 per year (or $8,000 if age 50 or older). If you put $4,000 in a traditional IRA, you can only contribute $3,000 to a Roth that year.

What happens if I withdraw money from a Roth IRA before age 59½?

You can withdraw your contributions anytime without penalty or tax. Withdrawals of earnings before 59½ are subject to income tax plus a 10% penalty, unless you meet an exception like disability, a first-time home purchase (up to $10,000 lifetime), or may have access to education expenses.

Do I have to pay taxes on a Roth conversion?

Yes. When you convert a traditional IRA to a Roth, you owe income tax on the amount converted in that tax year. The conversion itself is not penalized, but the tax bill can be substantial if you convert a large balance.

Which account should I open if I am self-employed?

You can open either a traditional or Roth IRA as a self-employed person, but you may benefit more from a SEP IRA or Solo 401(k), which allow much higher contributions. An IRA is still useful as a backup or supplemental account if you max out a SEP or Solo plan.

What is the five-year rule for Roth IRAs?

You must have owned a Roth IRA for at least five tax years before earnings withdrawals are tax-free. This applies even if you are over 59½. The five-year clock starts on January 1 of the year you open the account, not the date you fund it.
