Lower taxes in retirement. While traditional IRAs provide tax benefits today, Roth IRAs let you keep more of your retirement savings. Because contributions to traditional IRAs are tax-deductible, the IRS taxes the withdrawals you make in retirement. By contrast, contributions to Roth IRAs are not tax-deductible, but withdrawals in retirement are tax-free. Keep in mind that if your income exceeds $137,000 (or $202,999 for a couple filing jointly), you may not be eligible to contribute to these plans. But if you are, then high yield IRA certificates of deposit and money market accounts may be worth considering.
