Earned Income Credit
The Earned Income Tax Credit is a refundable credit that helps low and moderate income workers keep more of what they earn. When the amount of the credit exceeds the amount of income tax you owe, it could result in a refund.
In order to qualify for the Earned Income Credit, you must have earned income from employment or self-employment. Other income, such as interest and dividends, retirement income, social security, unemployment benefits, alimony, and child support do not count as earned income.
Note also that you cannot take the credit if you’re married but filing separately.

$43,998 ($49,078 if married filing jointly) with three or more qualifying children
$40,964 ($46,044 if married filing jointly) with two qualifying children
$36,052 ($41,132 if married filing jointly) with one qualifying child
