At what modified adjusted gross income level does the initial phase-out for the Child Tax Credit begin for single taxpayers?

The initial phase-out for the Child Tax Credit for single taxpayers begins at a modified adjusted gross income level of $200,000. When a single taxpayer's modified adjusted gross income exceeds this threshold, the amount of the credit starts to decrease. The credit is reduced by $50 for each $1,000 of modified adjusted gross income over this threshold.

This structure is designed to target the credit to middle and lower-income families, thus providing more support to those who may need it the most. Understanding the phase-out thresholds is critical for taxpayers to determine their eligibility for the full credit and any potential adjustments based on their income levels.
