The core difference: when you pay taxes
A Roth IRA and a traditional IRA are not the same. The biggest difference is when you pay income tax on the money. With a traditional IRA, you may deduct your contributions from your taxable income in the year you make them, and you pay taxes later when you withdraw the money in retirement. With a Roth IRA, you contribute money that has already been taxed, and you pay no taxes on withdrawals in retirement — including the growth your money earned.
This one difference shapes almost everything else about how each account works. It affects how much you can contribute each year, when you must start taking money out, who can use each account, and how much you actually keep when you retire.
Key Takeaways
- Traditional IRAs let you deduct contributions now and pay taxes on withdrawals later; Roth IRAs use after-tax money now and have tax-free withdrawals in retirement.
- Traditional IRAs require you to start withdrawals at age 73; Roth IRAs have no required withdrawals during your lifetime.
- Roth IRAs have income limits that may prevent high earners from opening one; traditional IRAs have no income limits.
- Both accounts hold the same types of investments (stocks, bonds, mutual funds, CDs) and have the same annual contribution limits.
- Your choice depends on whether you expect to be in a higher or lower tax bracket in retirement than you are now.
How contributions and deductions work differently
With a traditional IRA, you contribute pre-tax dollars. If you earned $60,000 last year and contributed $7,000 to a traditional IRA, you can deduct that $7,000 from your taxable income, so you only owe taxes on $53,000. The money grows tax-free inside the account, but you pay income tax on every dollar you withdraw after age 59½.
With a Roth IRA, you contribute money you have already paid taxes on. That same $7,000 comes from your after-tax income. You get no deduction now. But the money grows tax-free, and when you withdraw it in retirement, you owe nothing — not on the original $7,000 and not on any growth it earned.
The 2024 contribution limit is $7,000 per year for both account types if you are under age 50, or $8,000 if you are 50 or older. These limits are the same whether you choose traditional or Roth.
Income limits and who can open each account
Anyone with earned income can open a traditional IRA, regardless of how much money they make. There are no income limits. This makes traditional IRAs accessible to high earners who want a tax-deductible retirement savings option.
Roth IRAs have income limits that change each year. For 2024, you cannot contribute directly to a Roth IRA if your modified adjusted gross income (MAGI) exceeds $161,000 as a single filer or $240,000 as a married couple filing jointly. The limit phases out gradually — you can contribute a reduced amount if your income falls in a certain range. High earners can use a "backdoor Roth" strategy to work around this limit, but that requires specific steps and tax planning.
When you must take money out
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). 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 owe a penalty on the shortfall.
Roth IRAs have no required minimum distributions during your lifetime. You can leave the money untouched for as long as you want, and it continues to grow tax-free. This makes a Roth useful if you do not need the income in retirement or if you want to leave money to heirs.
Withdrawal rules and penalties
Both accounts penalize you for withdrawing money before age 59½, with one major exception. In a traditional IRA, any withdrawal before 59½ is taxed as income and hit with a 10% penalty — unless you may have access to for a narrow list of exceptions like disability, medical expenses, or a first-time home purchase (up to $10,000 lifetime).
In a Roth IRA, you can withdraw your original contributions at any time, tax-free and penalty-free. You can only withdraw the earnings (the growth) before age 59½ if you meet specific conditions, such as using the money for a first-time home purchase (up to $10,000 lifetime) or having held the account for at least five years. This flexibility makes Roth accounts more accessible if you face an emergency.
Tax brackets and which account makes sense for you
The choice between traditional and Roth often comes down to whether you expect to be in a higher tax bracket now or in retirement. If you are in a high tax bracket today and expect to be in a lower one in retirement, a traditional IRA saves you more in taxes now. If you are in a low tax bracket now and expect to be in a higher one later, a Roth IRA saves you more in taxes over your lifetime.
If you are unsure about your future tax bracket, a Roth offers more flexibility because you have already paid the tax and owe nothing later. You also have more control over when and how much you withdraw. A traditional IRA offers an immediate tax break, which can free up cash flow now if you need it.
The investments inside each account are the same
Both traditional and Roth IRAs can hold the same types of investments: stocks, bonds, mutual funds, exchange-traded funds (ETFs), certificates of deposit (CDs), and some alternative investments. The account type does not limit what you can buy. The difference is purely about the tax treatment of contributions and withdrawals, not about what you invest in.
Your choice of account should not be driven by what you want to own. Instead, choose the account type based on your tax situation, then invest the money inside it according to your goals and timeline.
Frequently Asked Questions
Can I have both a traditional IRA and a Roth IRA at the same time?
Yes. Your combined contributions to all traditional and Roth IRAs cannot exceed the annual limit ($7,000 in 2024 if you are under 50), but you can split that money between accounts however you want. Many people use both to balance their tax situation.
Can I convert a traditional IRA to a Roth IRA?
Yes, through a process called a Roth conversion. You move money from a traditional IRA to a Roth IRA and pay income tax on the amount converted in that year. There are no income limits on conversions, which is why high earners use the backdoor Roth strategy. Consult a tax professional before converting, because the tax bill can be substantial.
Which account should I choose if I am self-employed?
Both traditional and Roth IRAs work for self-employed people, but you may also want to explore a SEP IRA or Solo 401(k), which allow much higher contributions. If you choose between traditional and Roth, the same tax-bracket logic applies: traditional if you want a deduction now, Roth if you expect higher taxes later.
What happens to a Roth IRA if I die?
Your heirs inherit the account and can withdraw the money. They owe no income tax on the original contributions or earnings if the account was open for at least five years. This makes a Roth a powerful tool for leaving tax-free wealth to family members.
Do I pay taxes on investment growth in either account?
No. Both traditional and Roth IRAs shield investment growth from annual taxes while the money is in the account. The difference is what happens when you withdraw: traditional IRA withdrawals are taxed as income, while Roth withdrawals are tax-free.
