Once you have reached age 59½ and at least 5 years from the beginning of the year for which you first made a Roth IRA contribution, all regular distributions from your Roth IRAs are qualified distributions, tax and penalty free.
You do not get a tax deduction for a Roth IRA contribution. The benefit of the Roth IRA is that, once the requirements are met, all regular distributions from your Roth IRAs, including earnings in the Roth IRAs, will be tax and penalty free.
