Standard deduction

Under United States tax law, the standard deduction is a dollar amount that non-itemizers may subtract from their income before income tax is applied. Taxpayers may choose either itemized deductions or the standard deduction, but usually choose whichever results in the lesser amount of tax payable. The standard deduction is available to individuals who are US citizens or resident aliens. The standard deduction is based on filing status and typically increases each year, based on inflation measurements from the previous year. It is not available to nonresident aliens residing in the United States. Additional amounts are available for persons who are blind and/or are at least 65 years of age.
