The Core Difference: When You Pay Taxes

A Traditional IRA lets you deduct contributions from your 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 today), but your withdrawals in retirement are tax-free.

That single difference shapes everything else about how each account works. Which one makes sense for you depends on whether you think your tax rate will be higher now or later, how much you earn today, and when you plan to need the money.

Key Takeaways

  • Traditional IRA contributions may lower your taxable income this year, but withdrawals in retirement are taxed as ordinary income.
  • Roth IRA contributions do not reduce your taxes now, but may have access to withdrawals in retirement come out completely tax-free.
  • Income limits restrict who can contribute to a Roth IRA, but there are no income limits for Traditional IRA contributions.
  • Traditional IRAs require you to start taking withdrawals at age 73, while Roth IRAs have no mandatory withdrawal age during your lifetime.
  • You can convert a Traditional IRA to a Roth IRA at any time, though you will owe taxes on the converted amount in that year.

How Contributions and Tax Deductions Work

With a Traditional IRA, your contribution may be tax-deductible in the year you make it. If you earn $60,000 and contribute $7,000 to a Traditional IRA, you might report only $53,000 as taxable income. The IRS lets you deduct the full amount if you are not covered by an employer retirement plan, or if you are covered but your income falls below certain thresholds.

If your income is too high or you are already covered by a workplace 401(k) or pension, the deduction phases out or disappears entirely. Those income limits change each year and depend on your filing status.

A Roth IRA works differently. You contribute money that has already been taxed. There is no deduction, and your tax bill does not change. But the tradeoff is that the money grows tax-free inside the account, and you never pay tax on it again—including the growth.

Roth contributions are subject to income limits too. If you earn above a certain threshold (which varies by year and filing status), you cannot contribute directly to a Roth. Traditional IRAs have no income limit on contributions, though the deduction itself may be limited.

Withdrawals and Tax Treatment in Retirement

When you withdraw from a Traditional IRA, the entire amount is taxed as ordinary income in the year you take it out. If you withdraw $20,000, you add $20,000 to your taxable income for that year. This can push you into a higher tax bracket or affect other tax benefits you receive.

Roth withdrawals work the opposite way. Once you reach age 59½ and have held the account for at least five years, you can withdraw your contributions and earnings completely tax-free. The IRS does not care what your income is or what tax bracket you are in—the money comes out with no tax bill.

This difference matters most if you expect to be in a higher tax bracket in retirement than you are now, or if you simply want to avoid a large tax bill when you need the money. It also matters if you want to leave money to heirs; Roth beneficiaries inherit tax-free growth, while Traditional IRA beneficiaries owe income tax on distributions.

Required Withdrawals and Account Access

Traditional IRAs require 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 how much you must withdraw each year based on your age and account balance. If you do not take the full amount, you face a penalty of 25% on the shortfall (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, which makes them useful if you do not need the income or want to pass the account to heirs.

Both accounts penalize early withdrawals before age 59½, but Roth IRAs offer more flexibility. You can withdraw your contributions (not earnings) at any time without penalty, because you already paid tax on that money. Traditional IRAs charge a 10% penalty plus income tax on any withdrawal before 59½, with limited exceptions for hardship, disability, or medical expenses.

Income Limits and Who Can Contribute

Anyone with earned income can contribute to a Traditional IRA, regardless of how much they earn. However, if you or your spouse are covered by a workplace retirement plan, the tax deduction phases out above certain income levels. For 2024, single filers covered by a plan lose the deduction entirely above $77,000 of modified adjusted gross income; married couples filing jointly lose it above $123,000. These thresholds increase slightly each year.

Roth IRAs have direct income limits on who can contribute. For 2024, single filers can contribute the full amount up to $146,000 of modified adjusted gross income, then the contribution limit phases out and disappears at $161,000. Married couples filing jointly can contribute fully up to $230,000 and phase out completely at $240,000. These numbers change annually.

If your income exceeds the Roth limit, you cannot contribute directly. However, you can use a strategy called a backdoor Roth: contribute to a Traditional IRA (which has no income limit), then convert it to a Roth. This works if you have no other Traditional, SEP, or SIMPLE IRAs with pre-tax balances.

Converting Between Account Types

You can convert all or part of a Traditional IRA to a Roth IRA at any time. This is useful if you expect tax rates to rise, want to lock in current rates, or want to access the tax-free growth of a Roth.

The catch: you owe income tax on the converted amount in the year you convert it. If you convert $50,000 from a Traditional IRA to a Roth, you add $50,000 to your taxable income that year. This can trigger a large tax bill and push you into a higher bracket.

Some people do small conversions over several years to spread the tax impact. Others convert in years when their income is unusually low, such as after retirement or a job loss. There is no limit on how much you can convert, and no income limit on who can do it.

Which Account Makes Sense for You

Choose a Traditional IRA if you want to lower 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 useful if you have a high income now and want to save aggressively without hitting Roth income limits.

Choose a Roth IRA if you expect to be in a higher tax bracket later, want tax-free withdrawals in retirement, prefer flexibility on when to take money out, or want to leave tax-assistance programs to heirs. Roth accounts are also better if you are young and have decades of tax-free growth ahead.

Many people benefit from having both. You might contribute to a Traditional IRA to reduce taxes now, then do a backdoor Roth conversion in years when your income dips. Or you might split contributions between the two to hedge against future tax uncertainty.

Frequently Asked Questions

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

Yes. Your total contribution across all IRAs cannot exceed the annual limit (currently $7,000 for those under 50, $8,000 for those 50 and older), but you can split that between accounts however you want. Many people maintain both to get the tax benefits of each.

What happens to my IRA if I change jobs?

Your IRA stays with the financial institution where you opened it. You can roll a Traditional IRA from an old employer plan into your existing Traditional IRA, or roll a Roth 401(k) into a Roth IRA. Rolling money between account types of the same kind does not trigger taxes, but converting between Traditional and Roth does.

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

You can withdraw your contributions anytime without penalty. Earnings can be withdrawn penalty-free only if you are 59½ and have held the account for five years. Early withdrawal of earnings triggers a 10% penalty plus income tax, with limited exceptions for first-time home purchase, disability, or medical expenses.

Do I have to choose one account type and stick with it?

No. You can contribute to a Traditional IRA one year and a Roth the next. You can also convert between them. Your choice does not lock you in; you can adjust your strategy as your income, tax situation, and retirement timeline change.

What is the five-year rule for Roth IRAs?

To withdraw earnings tax-free from a Roth, you must be 59½ and have owned the account for at least five years. The five-year clock starts on January 1 of the year you make your first Roth contribution or conversion. If you convert a Traditional IRA to a Roth, a separate five-year clock starts for that conversion.
