Final answer:
Jacob will owe $29,900 in tax on the income allocation if the income is not qualified business income.
Step-by-step explanation:
The amount of tax Jacob will owe on the income allocation can be calculated by considering the self-employment tax and the additional Medicare tax. First, the self-employment tax is calculated by multiplying the business income by the self-employment tax rate (29%). So, the self-employment tax owed by Jacob is $100,000 * 29% = $29,000.The additional Medicare tax is calculated by multiplying the business income by the additional Medicare tax rate (0.9%). So, the additional Medicare tax owed by Jacob is $100,000 * 0.9% = $900.To calculate the total tax owed, we add the self-employment tax and the additional Medicare tax: $29,000 + $900 = $29,900.Therefore, Jacob will owe $29,900 in tax on the income allocation if the income is not qualified business income.
