Taxable income is defined as the amount of income that is subject to taxation after accounting for various deductions and exemptions. This means that taxable income reflects the portion of total income that is actually liable for income tax after you subtract allowable deductions—such as standard deductions, itemized deductions, and any applicable exemptions.

Understanding this definition is crucial for taxpayers because it helps in determining how much tax they owe. For instance, someone may have a large total income, but after considering deductions like mortgage interest, student loan interest, and other qualifying expenses, the taxable income might be significantly lower. This ultimately affects the tax bracket the taxpayer falls into and, therefore, the overall tax liability.

In contrast, the other options do not accurately reflect the definition of taxable income. The total yearly income before deductions fails to recognize the adjustments that reduce the income subjected to tax. Limiting the definition to income from employment ignores other sources of income such as investment earnings and rental income. Finally, stating that taxable income is the adjusted gross income minus taxes owed is misleading, as taxes owed are not subtracted from taxable income; they are calculated based on the taxable income itself.
