Final answer:
Marginal tax rate is the rate at which an additional dollar of income is taxed. To calculate the tax liability, we need to determine the tax bracket and use the formula provided in the table.
Step-by-step explanation:
Marginal tax rate is the rate at which an additional dollar of income is taxed. It is important to understand how marginal tax rate works in order to calculate the taxes owed at different income levels. Let's take the example of Travis who estimates his taxable income for the year to be $46,000. To determine Travis' marginal tax rate, we need to look at the tax rate brackets provided in the table.
- Travis falls in the second tax bracket which is taxed at a rate of 12%.
- Travis' taxable income falls in the range of $9,526 to $38,700.
- So, Travis' marginal tax rate is 12%.
To calculate Travis' tax liability, we can use the formula provided in the table. For Travis, the tax amount would be $952.50 plus 12% of income over $9,525.
To summarize, Travis' marginal tax rate is 12% because his taxable income falls in the corresponding tax bracket. Using the table, we can calculate his tax liability based on his taxable income using the provided formula.
