A Roth IRA is an individual retirement plan that is subject to the rules that apply to a traditional IRA, with some exceptions. For example, the account or annuity must be designated as a Roth IRA when it is opened.

Unlike a traditional IRA, you cannot deduct contributions to a Roth IRA. But, if you satisfy the requirements, qualified distributions are tax free.
