What Is the Standard Deduction?

The standard deduction is a fixed amount that US taxpayers can subtract from their income before federal income tax is calculated, without listing individual expenses. The amount depends on filing status and is adjusted for inflation each year. Taxpayers can instead itemize deductions if their eligible expenses are larger.

How It Works

Taxable income = adjusted gross income − standard deduction (or itemized deductions). A higher deduction means lower taxable income and therefore lower tax.

Standard vs. Itemized Deduction

Itemizing means listing specific deductible expenses, such as certain mortgage interest, state and local taxes (subject to limits), and charitable gifts. A taxpayer generally uses whichever total is higher.
