The Earned Income Tax Credit (EITC) provides substantial assistance to low-income working families with children. The credit encourages work for many, though may reduce work or wages for some. Counted in the poverty measure, the EITC would have been credited with lifting 6.5 million people out of poverty in 2012. The credit fails to provide substantial benefits to workers without children, is complicated, has a high erroneous payment rate, and creates substantial marriage penalties for some low- and moderate-income couples. Extending the credit to workers without children or replacing it with an individual worker credit could solve some or all of these criticisms.
