Final answer:
To calculate Stephanie's taxes, we need to determine which tax bracket her income falls into and apply the corresponding tax rates. Her taxable income is $16,050, $49,050, and $10,210 within each bracket respectively. Her total taxes for the year amount to $11,515.
Step-by-step explanation:
The marginal tax rate is the tax rate applied to an additional dollar of income. In this case, Stephanie's income of $75,310 falls within the highest tax bracket. Using the schedule provided, we can determine her taxes step by step:
- For the first $0 to $16,050, the tax rate is 10%. The taxable income within this bracket is $16,050.
- For the next $16,050 to $65,100, the tax rate is 15%. Since Stephanie's income falls within this bracket, the taxable income within this bracket is $65,100 - $16,050 = $49,050.
- Finally, for the amount over $65,100, the tax rate is 25%. Since Stephanie's income falls within this bracket, the taxable income within this bracket is $75,310 - $65,100 = $10,210.
To calculate her taxes:
- Taxes for the first bracket: $16,050 * 10% = $1,605
- Taxes for the second bracket: $49,050 * 15% = $7,357.50
- Taxes for the third bracket: $10,210 * 25% = $2,552.50
Therefore, Stephanie's total taxes for the year would be $1,605 + $7,357.50 + $2,552.50 = $11,515.
