A Roth IRA is not tax-deferred — it's tax-free

A Roth IRA works the opposite way from a tax-deferred account. With a tax-deferred account like a traditional IRA or 401(k), you reduce your taxable income in the year you contribute, then pay taxes on withdrawals in retirement. With a Roth IRA, you contribute money that has already been taxed, and then you pay no taxes on withdrawals — including the earnings — after age 59½.

The key difference: a traditional IRA defers taxes to later. A Roth IRA eliminates taxes on that money permanently. You do not get a tax break upfront, but you do not pay taxes on the growth or the withdrawals either.

Key Takeaways

  • Roth IRA contributions are made with after-tax dollars, so you do not reduce your taxable income in the year you contribute.
  • Withdrawals from a Roth IRA after age 59½ are tax-free, including all the money your account has earned over time.
  • A traditional IRA or 401(k) is tax-deferred: you get a tax deduction now and pay taxes on withdrawals later.
  • Choosing between a Roth and a tax-deferred account depends on whether you expect to be in a higher or lower tax bracket in retirement.

How tax-deferred accounts work

A tax-deferred account lets you put money in before taxes are taken out. When you contribute to a traditional IRA or a 401(k), that contribution amount reduces your taxable income for that year. If you earn $60,000 and contribute $7,000 to a traditional IRA, you report only $53,000 as taxable income.

The money grows inside the account without being taxed each year. But when you withdraw it in retirement, the full amount — your original contribution plus all the earnings — is taxed as ordinary income at whatever tax rate applies that year.

This approach makes sense if you expect to be in a lower tax bracket after you stop working. You save taxes at a high rate now and pay them at a lower rate later.

How a Roth IRA works instead

A Roth IRA takes the opposite path. You contribute money that you have already paid income tax on. That contribution does not reduce your taxable income, so there is no tax break in the year you contribute.

Inside the account, your money grows tax-free. When you withdraw it after age 59½, you owe no federal income tax on any of it — not on your contributions and not on the earnings. If your $7,000 contribution grows to $25,000 over 30 years, you withdraw all $25,000 with no tax bill.

This approach makes sense if you expect to be in a higher tax bracket in retirement, or if you straightforward want to lock in current tax rates and avoid uncertainty about future tax law.

The income limits that affect Roth contributions

You can only contribute to a Roth IRA if your income falls below a certain threshold. The limit changes each year and depends on your filing status. For 2024, single filers can contribute the full amount if their modified adjusted gross income is below $146,000. The ability to contribute phases out between $146,000 and $161,000. Married couples filing jointly can contribute fully up to $230,000, with the phase-out ending at $240,000.

If your income exceeds these limits, you cannot contribute directly to a Roth IRA. Some people use a strategy called a "backdoor Roth" to work around this limit, but that involves specific steps and tax reporting.

Traditional IRAs have no income limit for contributions, though the tax deduction phases out if you or your spouse have a workplace retirement plan and earn above a certain amount.

Withdrawal rules differ between the two

With a traditional IRA, you must start taking withdrawals at age 73 (as of 2023, under current law). These are called required minimum distributions, or RMDs. You cannot avoid them without penalty, even if you do not need the money.

A Roth IRA has no required minimum distributions during your lifetime. You can leave the money untouched as long as you want, which makes a Roth useful if you do not need the money in retirement or want to pass it to heirs.

You can withdraw your Roth contributions (not earnings) at any time without penalty or tax, even before age 59½. Withdrawing earnings before 59½ usually triggers a 10% penalty plus income tax, with some exceptions for hardship or first-time home purchase.

Tax brackets and which account makes sense for you

The choice between a Roth and a traditional account often comes down to tax brackets. If you are in a high tax bracket now and expect to be in a lower one in retirement, a traditional account saves you more money — you deduct at 32% and pay back at 22%, for example.

If you are in a lower bracket now and expect to be in a higher one later, or if you are uncertain about future tax rates, a Roth locks in your current rate. You pay tax at current rates and never pay it again, no matter how high rates climb.

Many people benefit from splitting contributions between both types. You might fund a traditional IRA to reduce your taxable income this year, then fund a Roth with other money to diversify your tax situation in retirement.

Employer plans and Roth options

Some employers offer a Roth 401(k) or Roth 403(b) alongside the traditional version. These work like a Roth IRA: you contribute after-tax dollars, the money grows tax-free, and withdrawals are tax-free after age 59½. The main difference is that Roth 401(k)s do have required minimum distributions, unlike Roth IRAs.

If your employer offers a Roth option, you can choose it, the traditional option, or split your contributions between both. This gives you the same tax-diversification benefit as splitting between a Roth IRA and a traditional IRA.

Frequently Asked Questions

Can I withdraw my Roth IRA contributions early without penalty?

Yes. You can withdraw the money you contributed (not the earnings) at any time without tax or penalty. Withdrawing earnings before age 59½ usually triggers a 10% penalty and income tax, though some exceptions exist for first-time home purchase or medical hardship.

Do I have to pay taxes on Roth IRA earnings when I withdraw them?

No, as long as you are at least 59½ and have held the account for at least five years. If you withdraw earnings before meeting both conditions, you owe income tax plus a 10% penalty on the earnings portion only.

What happens to a Roth IRA if I die?

Your heirs inherit the account and can withdraw the money. They do not pay income tax on withdrawals, though they must follow specific distribution rules depending on their relationship to you and when you opened the account.

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

Yes. You can own both types simultaneously. Your total contributions to all IRAs combined cannot exceed the annual limit ($7,000 for 2024 if you are under 50), but you can split that limit between them however you choose.

What if my income is too high for a Roth IRA?

You can still contribute to a traditional IRA with no income limit. Some people use a backdoor Roth strategy: contribute to a traditional IRA, then convert it to a Roth. This involves specific tax reporting and may trigger taxes depending on your other IRA balances.
