An important factor to consider when contributing to an IRA is eligibility. Both Traditional and Roth IRAs require an individual to have earned income in order to contribute. This includes various forms such as wages, salaries, bonuses, tips, commissions, and taxable alimony. These types of income are crucial for determining eligibility and maximizing contributions to these retirement accounts. It is essential to have a clear understanding of the eligibility requirements in order to make informed decisions about your financial future.
