<prompt> Human: I just opened a Fidelity Roth IRA account and contributed 5500 in it, all in Fidelity Freedom Index Fund 2055 just want to make sure Im doing it right. I know your supposed to be taxed now in Roth, but whenhow do I pay it?  <response>: You pay taxes on it because its not going to be reducing your taxable income this year. So in effect you are probably paying for it via withholding from your paycheck now, and at tax time youll make sure that you pay your tax on your entire taxable income.In contrast, people who invest in a traditional IRA get to deduct the amount they contribute from their taxable income when they file their taxes. If theyve already withheld more tax than necessary, the lowered taxable income means lower actual tax and theyd get a refund.
