For Child Tax Credit eligibility, what is the income threshold for married couples to receive the full credit?

For married couples to receive the full Child Tax Credit, the income threshold is set at $150,000. This means that if a married couple's modified adjusted gross income (MAGI) is at or below this amount, they are eligible to receive the full benefit of the credit for their qualifying children. As income exceeds this threshold, the credit begins to phase out. The Child Tax Credit is designed to assist families with the costs of raising children, and the income limits help to target the benefit towards those who need it most.

Other thresholds listed, such as $200,000 and $300,000, are not relevant to the full credit eligibility for married couples; these figures pertain to different tax considerations or may apply to individual filers. Thus, $150,000 is the correct income threshold for married couples to qualify for the full Child Tax Credit.
