Child tax credit
For each qualifying child under age 17 at the end of the year, you may qualify for the Child Tax Credit. The maximum credit is $2,000 per child. To receive the full tax credit, your modified adjusted gross income (MAGI) can't exceed $200,000, or $400,000 if you're married and filing a joint return. If your income exceeds these limits, you could receive a reduced amount.
Earned Income Tax Credit (EITC)
Claiming dependents could help you qualify for the earned income tax credit (EITC), available to working people with low- or mid-level incomes, or receive a larger tax credit.
Someone with no qualifying children and an adjusted gross income of as much as $17,640 (single and head of household filers) or $24,210 (married filing jointly) could receive a maximum credit of $600. But someone with three or more qualifying children could receive as much as $7,430 with an adjusted gross income of $56,838 (single and head of household filers) or $63,398 (married filing jointly).
