A Roth IRA is an individual retirement plan that, except as explained in this chapter, is subject to the rules that apply to a traditional IRA (defined below). It can be either an account or an annuity. Individual retirement accounts and annuities are described in chapter 1 under How Can a Traditional IRA Be Set Up.
To be a Roth IRA, the account or annuity must be designated as a Roth IRA when it is set up. A deemed IRA can be a Roth IRA, but neither a SEP IRA nor a SIMPLE IRA can be designated as a Roth IRA.
Unlike a traditional IRA, you cannot deduct contributions to a Roth IRA. But, if you satisfy the requirements, qualified distributions (discussed later) are tax free. Contributions can be made to your Roth IRA after you reach age 70╜ and you can leave amounts in your Roth IRA as long as you live.
A traditional IRA is any IRA that is not a Roth IRA or SIMPLE IRA.
