Final answer:
Carson's tax liability would be 15% of $12,700, which is $1,905.
Step-by-step explanation:
Carson's tax liability can be determined by calculating the tax on his income using the marginal tax rates. The marginal tax rates for a single taxpayer range from 10% to 35% depending on income. Since Carson's parents claimed him as a dependent and his parents' marginal tax rate is 28%, Carson's tax liability would be 28% of his income.
To calculate Carson's tax liability, we need to find out which tax bracket his income falls into. For 2017, the tax bracket for income between $9,325 and $37,950 has a marginal tax rate of 15%. Since Carson earned $12,700, his income falls within this bracket. Therefore, his tax liability would be 15% of $12,700, which is $1,905.
It's important to note that this is just an estimate of Carson's tax liability, as there may be other factors that could affect his tax situation. It's always a good idea to consult a tax professional for a more accurate calculation.
