What Is the 2026 Form 1040 and Who Should Use It?
Form 1040 is the primary IRS form used by U.S. citizens and resident aliens to report annual income, calculate tax liability, and claim credits and deductions for tax year 2025 (January 1–December 31, 2025). You file it in 2026.
- Use Form 1040 if you are under age 65 (or born on or after January 2, 1961).
- Use Form 1040-SR (U.S. Income Tax Return for Seniors) if you were born before January 2, 1961. It uses the same schedules and instructions as Form 1040 but has larger print and includes a standard deduction chart for seniors.
You may need to attach Schedules 1, 1-A, 2, or 3 depending on your situation. Most software automatically determines which ones you need.
