<human>:  What are the differences between a traditional IRA and a Roth IRA?
<bot>: The main difference between a traditional IRA and a Roth IRA is the difference in taxation. With a traditional IRA, contributions are tax-deductible, but withdrawals are taxed as ordinary income in retirement. With a Roth IRA, contributions are not tax-deductible, but withdrawals are not taxed, as the money has already been taxed. Additionally, traditional IRAs may have higher contribution limits than Roth IRAs. Both traditional and Roth IRAs provide opportunities for tax-free growth when managed properly.
