The core difference: when you pay taxes

A Traditional IRA lets you deduct contributions from your income taxes now, 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.

This is the single decision that shapes everything else about which account makes sense for your situation. If you expect to be in a lower tax bracket in retirement than you are now, a Traditional IRA often saves you more money overall. If you expect to be in the same bracket or higher, a Roth usually wins.

Neither choice is locked in forever. You can own both types of accounts at the same time, and you can convert money from a Traditional IRA to a Roth IRA later (though that conversion is a taxable event in the year you do it).

Key Takeaways

  • Traditional IRA contributions reduce your taxable income this year; Roth contributions do not, but Roth withdrawals in retirement are tax-free.
  • Traditional IRAs require you to start taking withdrawals at age 73; Roth IRAs have no withdrawal requirement during your lifetime.
  • You can only contribute to a Roth IRA if your income is below a certain limit, which changes yearly; Traditional IRAs have no income limit.
  • Both accounts hold the same investment types (stocks, bonds, mutual funds) and have the same annual contribution limit, which is $7,000 for 2024 if you are under 50.
  • If you withdraw Roth money before age 59½, you may owe taxes and penalties on the earnings, though contributions can come out penalty-free.

Income limits and who can contribute

Anyone with earned income can open and contribute to a Traditional IRA, no matter how much money they make. The only limit is the annual contribution cap ($7,000 in 2024 if you are under 50; $8,000 if you are 50 or older).

Roth IRAs have income limits that phase out your ability to contribute. For 2024, if you file taxes as a single person, you cannot contribute to a Roth if your Modified Adjusted Gross Income (MAGI) is $146,000 or more. If you are married filing jointly, the limit is $230,000. These numbers change each year. If your income falls between the lower and upper phase-out range, you can contribute a reduced amount.

If your income exceeds the Roth limit, you still have options: you can contribute to a Traditional IRA instead, or you can use a "backdoor Roth" strategy (converting a Traditional IRA contribution to a Roth). This is a legal workaround, but it has tax consequences if you already own other Traditional IRAs with pre-tax money in them.

Required withdrawals and account access

Traditional IRAs require you to begin 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 amount or face a penalty. This is called a Required Minimum Distribution (RMD).

Roth IRAs have no RMD requirement during your lifetime. You can leave the money untouched as long as you live, which makes a Roth useful if you do not need the money in retirement or want to pass it to heirs. Your beneficiaries will eventually have to withdraw the money, but on a different schedule than Traditional IRA beneficiaries.

Before age 59½, both account types penalize you for withdrawals of earnings (the investment gains). With a Roth, you can withdraw your contributions penalty-free at any time, since you already paid taxes on that money. With a Traditional IRA, any withdrawal before 59½ is taxed as income plus a 10% penalty, with limited exceptions (first-time home purchase, medical expenses, disability).

If you have a Traditional IRA and you are also covered by a workplace retirement plan (like a 401k), your ability to deduct Traditional IRA contributions phases out above a certain income. For 2024, if you are single and covered by a workplace plan, the deduction phases out between $77,000 and $87,000 of income. This does not prevent you from contributing to the account—it just means the contribution would not reduce your taxes.

Investment options and account management

Both Traditional and Roth IRAs can hold the same types of investments: individual stocks, bonds, mutual funds, exchange-traded funds (ETFs), and some alternative investments. The account itself is just a container; the investments inside are what grow (or shrink) over time.

You open an IRA through a brokerage, bank, or investment firm. Popular providers include Fidelity, Vanguard, Charles Schwab, and others. The provider holds the account and executes your trades, but you decide what to buy and sell within it. Some providers offer robo-advisors that automatically build and rebalance a portfolio for you, usually for a small fee.

Both account types have the same annual contribution limit: $7,000 in 2024 if you are under 50, or $8,000 if you are 50 or older. This limit is shared across all IRAs you own—if you have both a Traditional and a Roth, your combined contributions cannot exceed the limit in any single year.

Conversions and rollovers between accounts

You can move money from a Traditional IRA to a Roth IRA through a conversion. The amount you convert is treated as taxable income in the year of the conversion, but once the money is in the Roth, future growth and withdrawals are tax-free. Conversions make sense if you expect tax rates to rise, or if you want to lock in a lower tax bracket in a particular year.

If you leave a job and have a 401k, you can roll it into either a Traditional IRA or a Roth IRA. A rollover to a Traditional IRA keeps the pre-tax status of the money. A rollover to a Roth is treated as a conversion and creates a tax bill in that year. You have 60 days from the time you receive the money to complete the rollover, or the IRS treats it as a withdrawal.

You cannot undo a conversion or rollover by simply moving the money back. If you convert to a Roth and change your mind, you can recharacterize the contribution (move it back to a Traditional IRA), but only within the tax-filing deadline for that year, including extensions.

Which account type might work better for you

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 your income is too high to contribute to a Roth. Traditional IRAs are also useful if you have a lot of pre-tax money already (like from a 401k) and want to keep that money in one account type.

Choose a Roth IRA if you are early in your career (likely to be in a higher tax bracket later), expect tax rates to rise, want tax-free withdrawals in retirement, or want the flexibility to withdraw contributions without penalty. A Roth is also valuable if you want to leave money to heirs tax-free, or if you do not want to be forced to take withdrawals at a certain age.

Many people benefit from owning both. You might max out a Roth while you are young and in a lower bracket, then switch to Traditional contributions later when your income rises and the tax deduction becomes more valuable. A tax professional can model your specific situation and help you decide.

Frequently Asked Questions

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

Yes, but your combined contributions to all IRAs cannot exceed the annual limit ($7,000 in 2024 if you are under 50). If you contribute $4,000 to a Traditional IRA, you can only contribute $3,000 to a Roth that same year.

What happens to my Roth IRA if I die?

Your beneficiaries inherit the account and can withdraw the money tax-free (since you already paid taxes on it). They must withdraw the balance within 10 years under current rules, though the withdrawal schedule depends on their relationship to you and when you died.

Can I deduct Traditional IRA contributions if I have a 401k at work?

It depends on your income. If you are covered by a workplace retirement plan, your Traditional IRA deduction phases out above a certain income threshold. For 2024, if you are single, the phase-out range is $77,000 to $87,000. You can still contribute to the IRA; the contribution just would not reduce your taxes.

What is a backdoor Roth, and do I need one?

A backdoor Roth is a strategy where you contribute to a Traditional IRA (no deduction) and then immediately convert it to a Roth. It works if your income is too high for a direct Roth contribution. However, if you already have other Traditional IRAs with pre-tax money, the conversion triggers taxes on a portion of that money, so consult a tax professional first.

Do I have to pay taxes on Roth withdrawals if I withdraw before age 59½?

You can withdraw your contributions penalty-free at any age. If you withdraw earnings (investment gains) before 59½, you owe income tax plus a 10% penalty on the earnings, unless you may have access to for an exception like disability or a first-time home purchase.
