Effective 2019, the Personal Exemption Allowance was eliminated. In the same year, the Child Tax Credit doubled from $1,000 to $2.000 per child. The Personal Exemption Allowance 2was $4.150 for each exemption. So, a family of 4 (2 adults and 2 children) could claim an exemption of $16,600. If the 2 children are under 17, the family loses the exemption (deduction) but recognizes an additional $2,000 in tax credits. Assume a Personal Exemption Allowance of $4,150 per individual. Assume a 22% marginal tax rate. Q: What is the net tax benefit for every child under 17? Q: How many children under the age of 17 will create a break-even tax responsibility? Q: Assume a family of 4, with 2 children under 17. What marginal tax rate creates a break-even result? What does this mean?
