Retirement Savings Tax Credit
Taxpayers who make contributions to IRAs and/or salary deferrals under retirement plans may qualify for an income tax credit if their income is under certain amounts. Contributions of up to $2,000 may be eligible for credits that range from 10 to 50 percent of the amount contributed.
Eligibility is based on income and tax filing status as defined in the instructions for Form 8880, Credit for Qualified Retirement Savings Contributions, and these income limits are subject to cost-of-living adjustments. The maximum income thresholds in all categories for this credit will increase for 2018. For 2018, taxpayers with adjusted gross income that exceeds $63,000 for joint filers, $47,250 for head of household, and $31,500 for all other filers will not qualify for a tax credit.
