You don’t get a tax deduction for making a Roth IRA contribution the way you would if it were a traditional IRA. But, that also means that the contributions will not be taxable when they’re withdrawn.
In addition, if you do not begin withdrawing funds until after you turn 59 ½ – and if you have had your Roth IRA for at least five years – there are also no income taxes levied on your investment earnings either.
