Which calculation is necessary to determine the taxable income for someone with multiple deductions?

To determine the taxable income for an individual with multiple deductions, it is essential to calculate their income minus the total deductions they are eligible for. Taxable income is essentially the amount on which income tax is actually calculated.

This process begins by taking the individual's total income, which includes various sources of revenue like salary, bonuses, or investment income. From this total income, you subtract the allowable deductions, which can include expenses like contributions to retirement accounts, interest on loans, and other specific deductions prescribed by tax laws. The resulting figure is the taxable income, the base amount used to assess how much tax the individual owes.

In contrast, adding deductions to total income, calculating total assets against liabilities, or applying the tax rate to net income do not derive taxable income directly, making those options less relevant for this specific calculation.
