Final answer:
The marginal tax rate for Lorenzo when his annual taxable income is $110,000 is 24%. He owes approximately $20,223.75 in income taxes for 2022. His average tax rate is around 18.38%.
Step-by-step explanation:
The marginal tax rate is the rate at which the last dollar is taxed. In this case, Lorenzo's marginal tax rate is determined by the IRS tax rates for a single taxpayer in 2022. Since his annual taxable income is $110,000, we look at the table and see that the tax rate for that income range is 24%. So Lorenzo's marginal tax rate is 24%.Now let's calculate the amount he owes in income taxes for 2022. We can use the formula: tax = base_tax + (marginal_tax_rate × (taxable_income - base_income)). Since Lorenzo's taxable income is $110,000, and the base income is $85,525 (the income range right below $110,000), we have: tax = $14,313.75 + (0.24 × ($110,000 - $85,525)) = $14,313.75 + $5,910 = $20,223.75.To calculate the average tax rate, we divide the total tax paid by the taxable income. So Lorenzo's average tax rate is $20,223.75 ÷ $110,000 ≈ 0.1838, or about 18.38%.
