Taxable Income

Definition

Taxable income is the portion of an individual or business’s income that is subject to federal, state, or local taxes after accounting for deductions and exemptions.


Detailed Explanation

Taxable income is a critical component in calculating the amount of tax owed to the government. It represents the income remaining after you subtract all allowable adjustments, deductions, and exemptions from total income. For individuals, taxable income starts with gross income, which includes wages, salaries, interest, dividends, rental income, and other earnings.

Adjusted gross income (AGI) is calculated by subtracting specific adjustments such as retirement contributions, student loan interest, and educator expenses. From AGI, taxpayers can deduct either the standard deduction or itemized deductions, along with any personal exemptions (if applicable), to arrive at taxable income.

Businesses calculate taxable income by subtracting operating expenses, depreciation, and other deductible costs from their gross revenue. Both individuals and businesses are subject to tax rates applied to their taxable income, which can vary depending on their filing status or the type of entity. Taxable income is used to determine liability for federal income tax, state income tax (if applicable), and other taxes, such as self-employment tax.

Taxable income does not include non-taxable income, such as some Social Security benefits, municipal bond interest, or qualified distributions from certain accounts like Roth IRAs.

Example

An individual earns $80,000 in gross income, subtracts $10,000 in adjustments, and claims a $12,950 standard deduction. Their taxable income is $57,050.
