We estimate income effects on earnings using the 2021 expanded Child Tax Credit. We find that employment as reported by third parties decreased by 2.0% in 2021 and 1.1% in 2022 in low-income families in response to $600 of non-labor income, with no effect on families with higher incomes. However, this decrease in wages was offset by an equivalent increase in self-employment income reported on tax returns, implying either increased misreporting or no overall change in real employment.
