You can get up to $3,000 for children ages 6 to 17 and $3,600 for children ages 5 and under, up from $2,000 for kids of all ages. To receive the full tax credit, your adjusted gross income (AGI) must be under $75,000 (Single); $150,000 (Married Filing Jointly); or $112,500 (Head of Household). If your income is above the aforementioned thresholds, you can still receive $2,000 per child if your income is less than $200,000 (single, Head of Household); or $400,000 (Married filing Jointly).
