Forms for reporting and paying individual federal income tax. Includes the main Form 1040, amended returns (1040-X), estimated tax payments (1040-ES), non-resident returns (1040-NR), and senior returns (1040-SR).
The 1040 series is the backbone of individual income tax filing in the United States. Form 1040 is the standard individual tax return used by nearly every American taxpayer. The series includes specialized variants: 1040-SR for seniors with larger print and enhanced deductions, 1040-NR for non-resident aliens with U.S. income, 1040-X for amending previously filed returns, and 1040-ES for quarterly estimated tax payments. Supporting schedules (Schedule A for itemized deductions, Schedule C for business profit/loss, Schedule D for capital gains, Schedule SE for self-employment tax, and others) are used alongside these forms to report specific types of income, deductions, and credits. Most forms in this series are filed annually by April 15.
