Who qualifies as an 'eligible child' for the Child Tax Credit?

There are 7 requirements each child must meet to qualify as an eligible child for purposes of the CTC:

  1. Must be under age 17 (still 16) at the end of the relevant tax year (age requirement);
  2. must be your child, a stepchild, or a legal foster child (relationship requirement);
  3. must not have provided more than half of his or her own financial support during the tax year (support requirement);
  4. must qualify and be claimed as a dependent on your tax return (dependent requirement);
  5. must be a US citizen, US national or US resident alien (citizenship requirement);
  6. must have lived with you for at least half of the relevant tax year (residence requirement); and
  7. must not have filed a joint return for the tax year (or only filed as a claim for a refund).

Make sure you file the right form to receive the Child Tax Credit

If you file your federal tax return using Form 1040EZ or Form 1040NR-EZ, you cannot claim the CTC. Make sure you use Form 1040, Form 1040A or Form 1040NR to retain your CTC eligibility.

You will need to complete your appropriate federal tax form before you can calculate the amount of your Child Tax Credit, if any. Once you have finished your forms, calculate your Child Tax Credit using IRS Publication 972.
