Congress has limited who can contribute to a Roth IRA based upon income. A taxpayer can contribute the maximum amount listed at the top of the page only if their Modified Adjusted Gross Income (MAGI) is below a certain level (the bottom of the range shown below). Otherwise, a phase-out of allowed contributions runs proportionally throughout the MAGI ranges shown below. Once MAGI hits the top of the range, no contribution is allowed at all; however, a minimum of $200 may be contributed as long as MAGI is below the top of the range (e.g., a single 40-year-old with MAGI $124,999 may still contribute $200 to a Roth IRA vs. $30). Excess Roth IRA contributions may be recharacterized into Traditional IRA contributions as long as the combined contributions do not exceed that tax year's limit. The Roth IRA MAGI phase out ranges for 2021 are:
