Child Tax Credit Increased

Under pre-Act law, a taxpayer could claim a child tax credit of up to $1,000 per qualifying child under the age of 17. The aggregate amount of the credit that could be claimed phased out by $50 for each $1,000 of AGI over $75,000 for single filers, $110,000 for married filers, and $55,000 for married individuals filing separately. To the extent that the credit exceeded a taxpayer's liability, a taxpayer was eligible for a refundable credit (i.e., the additional child tax credit) equal to 15% of earned income in excess of $3,000 (the “earned income threshold”). A taxpayer claiming the credit had to include a valid Taxpayer Identification Number (TIN) for each qualifying child on their return. In most cases, the TIN is the child's Social Security Number (SSN), although Individual Taxpayer Identification Numbers (ITINs) were also accepted.

New law. For tax years beginning after Dec. 31, 2017 and before Jan. 1, 2026, the child tax credit is increased to $2,000, and other changes are made to phase-outs and refundability during this same period, as outlined below

Phase-out. The income levels at which the credit phases out are increased to $400,000 for married taxpayers filing jointly ($200,000 for all other taxpayers)

Non-child dependents. In addition, a $500 nonrefundable credit is provided for certain non-child dependents.

Refundability. The amount of the credit that is refundable is increased to $1,400 per qualifying child, and this amount is indexed for inflation, up to the base $2,000 base credit amount. The earned income threshold for the refundable portion of the credit is decreased from $3,000 to $2,500.

SSN required. No credit will be allowed to a taxpayer with respect to any qualifying child unless the taxpayer provides the child's SSN.
