The choice depends on your tax bracket now versus later, not on which account is objectively "better"

A Roth IRA and a traditional IRA are two different ways to save for retirement, and which one makes sense for you depends on whether you want to pay taxes now or in retirement. With a Roth, you contribute money you've already paid taxes on, and withdrawals in retirement are tax-free. With a traditional IRA, you may deduct contributions from your current income (lowering your taxes this year), but you pay income tax on withdrawals later. Neither is universally better — the right choice depends on your current income, how much you expect to earn in retirement, and your state's tax situation.

Key Takeaways

  • Roth contributions are made with after-tax money, but may have access to withdrawals in retirement are completely tax-free; traditional contributions may reduce your taxes now, but withdrawals are taxed as income later.
  • If you expect to be in a higher tax bracket in retirement, a Roth usually makes more sense; if you expect to be in a lower bracket, a traditional IRA often saves you more money overall.
  • Roth IRAs have no required minimum distributions during your lifetime, while traditional IRAs force you to start withdrawing at age 73, which can push you into a higher tax bracket.
  • Income limits restrict who can contribute directly to a Roth IRA, but there is no income limit for traditional IRA contributions; however, the tax deduction phases out for higher earners with workplace retirement plans.
  • You can withdraw Roth contributions (not earnings) at any time without penalty, but traditional IRA withdrawals before age 59½ typically trigger a 10% penalty plus income tax.

How taxes work in each account type

With a traditional IRA, you put money in before taxes are taken out. If you meet the income requirements, you deduct that contribution on your tax return for the year you make it — so a $7,000 contribution might lower your taxable income by $7,000. That means you pay less in federal income tax that year. But when you withdraw money in retirement, every dollar comes out as ordinary income and gets taxed at whatever your tax rate is then.

With a Roth IRA, you contribute money you've already paid taxes on. You do not get a tax deduction now. But when you withdraw money in retirement — whether it's the money you put in or the growth it earned — you owe no federal income tax on any of it. This is the core trade-off: pay taxes on the way in (Roth) or on the way out (traditional).

The math changes based on your tax bracket. If you are in the 22% tax bracket now and expect to be in the 22% bracket in retirement, both accounts end up costing you the same amount in total taxes over your lifetime. But if you are in the 22% bracket now and expect to be in the 32% bracket in retirement, the Roth saves you money because you locked in the lower rate. The reverse is true if you expect your retirement income to be lower than your working income.

Income limits and who can contribute

A traditional IRA has no income limit — anyone with earned income can open one and contribute. However, if you or your spouse have access to a workplace retirement plan (like a 401(k)), the tax deduction phases out at higher incomes. For 2024, if you are single and covered by a workplace plan, the deduction begins to phase out at $77,000 in income and disappears entirely at $87,000. If you are married filing jointly and your spouse has a workplace plan, the phase-out starts at $123,000 and ends at $143,000. These numbers change yearly.

A Roth IRA has strict income limits on who can contribute directly. For 2024, if you are single, you can contribute the full amount if your income is below $146,000; the contribution phases out between $146,000 and $161,000, and you cannot contribute at all above $161,000. If you are married filing jointly, the limits are $230,000 to $240,000. These limits also change each year. If your income exceeds the Roth limit, you cannot contribute directly, though you may be able to use a "backdoor Roth" strategy (converting a traditional IRA to a Roth) — that is a separate process with its own rules.

Withdrawal rules and flexibility

With a traditional IRA, you generally cannot withdraw money before age 59½ without paying a 10% penalty on top of income tax. There are narrow exceptions (first-time home purchase up to $10,000, certain medical expenses, disability), but they do not cover everyday needs. At age 73, you are required to start taking withdrawals — called required minimum distributions (RMDs) — whether you need the money or not. The amount is calculated based on your age and account balance. These forced withdrawals can push you into a higher tax bracket and affect other benefits like Medicare premiums or Social Security taxation.

With a Roth IRA, you can withdraw your contributions (the money you put in) at any time, tax-free and penalty-free. You cannot withdraw earnings before age 59½ without a penalty, but the contribution portion is always accessible. You are never required to take distributions during your lifetime — the money can sit and grow tax-free for as long as you live. This makes a Roth useful if you do not need the money in retirement or want to leave it to heirs.

Which account makes sense for different situations

A Roth IRA usually makes more sense if you are young, in a low tax bracket now, expect your income to rise significantly, or believe tax rates will be higher in the future. Young workers have decades for money to grow tax-free, and locking in today's tax rate (often lower when you are starting out) is usually a good deal. It also works well if you want flexibility — you can access contributions without penalty, and you are not forced to withdraw in retirement.

A traditional IRA usually makes more sense if you are in a high tax bracket now and expect to be in a lower one in retirement, or if you need the immediate tax deduction to lower your current tax bill. It can also be the only option if your income exceeds Roth limits. If you have a workplace retirement plan and earn too much to deduct traditional IRA contributions, a Roth becomes more attractive (assuming you are under the Roth income limit).

Some people use both. You can contribute to a traditional IRA and a Roth IRA in the same year, but your total contributions to both accounts cannot exceed the annual limit ($7,000 for 2024 if you are under 50; $8,000 if you are 50 or older). Splitting contributions between the two accounts lets you hedge your tax-rate bet.

Contribution limits and catch-up contributions

Both account types have the same annual contribution limit: $7,000 per year for 2024 if you are under age 50. If you are 50 or older, you can contribute an additional $1,000 per year as a "catch-up" contribution, for a total of $8,000. These limits apply to your combined contributions across all traditional IRAs and all Roth IRAs — you cannot contribute $7,000 to each. The limits are adjusted yearly for inflation.

Unlike a 401(k), neither IRA type allows you to contribute more just because you have high income. The limit is the same whether you earn $50,000 or $500,000 per year (though the Roth income cap may prevent you from contributing at all if you earn too much).

Frequently Asked Questions

Can I switch from a traditional IRA to a Roth IRA?

Yes, through a process called a conversion. You withdraw money from your traditional IRA and deposit it into a Roth IRA within 60 days. You will owe income tax on the amount converted in the year you do it, but the money then grows tax-free in the Roth. Conversions are useful if you expect tax rates to rise or if you want to access the money more flexibly in retirement.

What happens to my IRA when I die?

Your heirs inherit the account, but the tax treatment differs. Beneficiaries of a traditional IRA must pay income tax on withdrawals. Beneficiaries of a Roth IRA can withdraw contributions tax-free and earnings tax-free if the account has been open at least five years. This makes a Roth a better tool for leaving money to heirs.

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

Yes, but your total contributions to both accounts in a single year cannot exceed the annual limit. If you contribute $4,000 to a traditional IRA, you can only contribute $3,000 to a Roth that same year (assuming the $7,000 limit for 2024).

What if I have a 401(k) at work — should I still open an IRA?

Many people do both. A 401(k) and an IRA are separate accounts with separate contribution limits. You can contribute to both in the same year. However, if you have a workplace plan, the tax deduction for a traditional IRA phases out at higher incomes, which may make a Roth IRA more attractive if you are under the Roth income limit.

Do I have to report my IRA on my taxes?

You report contributions and withdrawals on your tax return. For a traditional IRA, you deduct contributions if you meet the income requirements. For a Roth, contributions are not deductible, but you report them so the IRS knows you have already paid tax on that money. Your IRA custodian sends you a form each year showing what you contributed and withdrew.
