Answer:
To determine Gabriel's tax liability, we need the specific tax brackets for 2019 as the U.S. income tax system is progressive and rates increase with income. Without these brackets, we can't accurately calculate his tax, but it's certain that his marginal rate is at the uppermost tier for a single taxpayer.
Step-by-step explanation:
To calculate Gabriel's tax liability, we need to understand that income tax in the United States for individuals is a progressive tax, which means as a person's income increases, the tax rates also increase. These rates depend on marital status, family size, and income. Based on the information provided and considering the marginal tax rates for a single taxpayer which range from 10% to 35%, calculating the precise tax without the specific tax brackets for 2019 is not feasible. However, given the progressive nature of the tax system, the tax liability would increase incrementally within the applicable range.
As an example, if a single taxpayer's income were $35,000: income up to $9,075 would be taxed at 10%, the income from $9,075 to $36,900 at 15%, and income above $36,900 at the next bracket. Since Gabriel's taxable income is $1,300,000, his marginal rate would likely be at the highest tax bracket for that year.
