Build a checker for federal and state earned income and child tax credits

The IRS estimates about one in five eligible workers miss the Earned Income Tax Credit, and 31 states plus DC have their own EITC on top of it. Fifteen states also offer a child tax credit. Most people have no idea their state has one. Build a quick checker that shows which federal and state credits someone likely qualifies for and how to claim them.
