The Earned Income Tax Credit program offers a tax credit for federal taxes paid by low income tax payers at the end of the tax year. Qualified recipients must submit a tax return, even if they do not owe taxes, and have earned income during the year. In Maryland there is a state version of the program that recipients can also apply for when they complete the federal version.
