Retirement-conscious investors have long recognized the benefits of the traditional IRA. Another alternative is the Roth IRA. Roth IRAs permit you to avoid future taxation of your retirement funds by making nondeductible contributions now. Contributions are limited to the lesser of 100% of your earned income or $6,000 a year in 2020 ($12,000 for couples) and are made on an after-tax basis. Also, individuals aged 50 and older can make an additional catch-up contribution of $1,000 in 2020. Certain income eligibility limits apply. Note that an individuals total contributions to all IRAs -- Roth and traditional -- may not exceed $6,000 annually ($7,000 if age 50 or older).
