Roth IRAs were created for middle-income tax payers who are active participants in employee-sponsored retirement plans along iwth younger taxpayers in lower brackets that prefer tax-free withdrawals over current tax savings. Basically, contributions to Roth IRAs are not tax-deductible but earnings grow tax deferred and can be withdrawn tax-free in retirement or put towards certain other assets at an earlier age. One major limit of the Roth IRA is that it adds a maximum income level while joint filers may contibute the lesser of $2,000 or 100% of their compensation (earned income) as long as their combined annual income is below $150,000. Allowable contributions above that are phased-out completely at $160,000. And for individuals, the $2,000 maximum allowable contribution begins to be phased-out at $95,000 and reaches zero at $110,000.
