The Child Tax Credit Improvement Act of 2014 (H.R. 4935) is a bill that would amend the Internal Revenue Code with respect to the child tax credit. The bill would require taxpayers claiming the child tax credit to provide their Social Security Numbers, a change that would prevent undocumented immigrants from claiming the credit. The bill would index the child credit to inflation. The bill was introduced into the United States House of Representatives during the 113th United States Congress.
