A child tax credit number is an identification number assigned to a taxpayer who claims the child tax credit. This number is used to track the taxpayer’s eligibility for the credit.
The child tax credit is a tax break that helps families offset the costs of raising children. The credit is available to taxpayers who have qualifying children under the age of 17. The amount of the credit varies depending on the taxpayer’s income. The child tax credit was first enacted in 1997 and has been expanded several times since then.
