A Roth IRA is an individual retirement account (IRA) under United States law that is generally not taxed upon distribution, provided certain conditions are met. The principal difference between Roth IRAs and most other tax-advantaged retirement plans is that rather than granting a tax reduction for contributions to the retirement plan, qualified withdrawals from the Roth IRA plan are tax-free, and growth in the account is tax-free.[1][2]
The Roth IRA was introduced as part of the Taxpayer Relief Act of 1997 and is named for Senator William Roth.
