Which of the following describes the characteristics of a Roth IRA?

The characteristic that aligns with a Roth IRA is that contributions are limited and not tax-deductible. This means that while you can contribute only up to a certain amount each year (which is set by the IRS and may vary based on your age and income), the contributions made to a Roth IRA do not reduce your taxable income for the year they are made. Instead, the advantage of a Roth IRA lies in the fact that any qualified withdrawals, including earnings, are tax-free in retirement.

In contrast, traditional IRAs allow for tax-deductible contributions but have different tax implications when distributions are taken during retirement. Options that suggest either all contributions are tax-exempt or there are no contribution limits do not accurately reflect the rules governing Roth IRAs. Therefore, the correct understanding is that contributions are capped at a certain limit and do not provide a tax deduction at the time of contribution.
