  • you must determine how many qualifying children you can claim based on the six tests mentioned above.
  • multiply the number of dependent children you can claim by $1,000 (maximum amount of the Child Tax Credit.
  • determine your modified adjusted gross income (MAGI). This amount can be found on Form 1040, line 38; Form 1040A, line 22; or Form 1040NR, line 37.
  • subtract your MAGI by the following amounts below depending on your filing status:
    • Married ling jointly: $110,000
    • Single, head of household, or qualifying widow(er): $75,000
    • Married filing separately: $55,000
  • for every $1,000 the MAGI exceeds the limitations above, the amount of tax credit allowed to be claimed is reduced by $50.


A single taxpayer with 2 qualifying children and modified adjusted gross income (MAGI) of $80,000 can claim a Child Tax Credit of $1,750.

Step 1: Number of Children x $1,000 Maximum Credit.

2 Children x $1,000 = $2,000

Step 2: Determine the modified adjusted gross income (MAGI) which is calculated on your Form 1040.

MAGI = $80,000

Step 3: Subtract the MAGI by the limitation mentioned above based on your filing status. If your MAGI is less than the limitation, you are eligible for the full credit of $1,000.

$80,000 – $75,000 (limitation for single filers) = $5,000.

Step 4: For every $1,000 the MAGI exceeds the limitations above, the amount of tax credit allowed to be claimed is reduced by $50.

5 x $50 = $250.

Step 5: $2,000 – $250 = $1,750. This is maximum amount of child tax credit that this individual can claim.

Additional Child Tax Credit

Generally, the Child Tax Credit is a non-refundable credit. This means that the tax credit can only offset tax liability to $0 but any excess will not be refunded to the individual. However, in certain cases, individuals can claim the additional child tax credit which is a refundable tax credit. A refundable tax credit can lower the tax liability to $0 and any excess will result in additional refund to the taxpayer.

The additional child tax credit is available to those who earned over $3,000 of income and did not claim the full child tax credit. The calculation for this credit can get more complex so it’s advised to use tax software or contact your tax advisor. Part 2 of Schedule 8812 will be used to claim the refundable Additional Tax Child Credit.

How to Claim the Child Tax Credit

The child tax credit must be claimed on Form 1040, line 52; Form 1040A, line 35; or Form 1040NR, line 49. You must identify each child with their name and social security number. If the child you are claiming has an Individual Taxpayer Identification Number (ITIN) instead of a social security number, Schedule 8812 will need to be prepared and attached with your tax return.


The Child Tax Credit is designed to help families with children and reduce the number of children living in poverty. This tax credit has helped millions of families with the high costs of child care.
