Final answer:
A Roth IRA is a tax-free investment account where contributions are made after taxes and qualified withdrawals at retirement are tax-free.
Step-by-step explanation:
A Roth IRA is a type of Individual Retirement Account where contributions are made after taxes, and qualified withdrawals at retirement are tax-free. This means that any earnings on your contributions grow tax-free and you do not need to pay taxes on the withdrawals at retirement. The maximum annual contribution limit for a Roth IRA is the lesser of $6,000 or 100% of earned income. Additionally, there is a requirement of a five-year holding period to be satisfied for a distribution to be qualified.
