IRS tax forms used in 2026 do not all belong to the same tax year. Most individuals filing during the 2026 tax season use a 2025 Form 1040 because the return reports income earned in 2025. Meanwhile, forms such as the 2026 Form W-4, Form 941, and Form 1040-ES apply to payroll withholding, employer reporting, or estimated payments during calendar year 2026.
This directory explains that distinction and connects users to government-hosted forms. Always confirm the revision or tax year printed on the PDF before filing.

Individual Income Tax Forms Filed in 2026
Form 1040 — U.S. Individual Income Tax Return
Most U.S. citizens and residents use Form 1040. For the return normally due in 2026, use the 2025 revision because it reports 2025 income. Common schedules include Schedule 1 for additional income and adjustments, Schedule 2 for additional taxes, and Schedule 3 for additional credits and payments.
Form 1040-SR — U.S. Tax Return for Seniors
Form 1040-SR is an optional Form 1040 alternative for taxpayers age 65 or older. It uses larger print and follows the same basic tax rules as Form 1040.
Form 1040-NR — U.S. Nonresident Alien Income Tax Return
Form 1040-NR is for nonresident alien individuals and certain estates and trusts. Residency classification can be complex; review the official instructions rather than choosing a form solely from immigration status.
Form 1040-X — Amended U.S. Individual Income Tax Return
Use Form 1040-X to correct an eligible previously filed individual return. The IRS permits electronic filing for certain current and prior-year amended returns, while paper filing remains available.
2026 Withholding and Estimated-Tax Forms
2026 Form W-4
Employees give Form W-4 to employers to establish federal income tax withholding. It is not an annual income tax return. See our 2026 Form W-4 guide or download the official IRS PDF.
2026 Form 1040-ES
Individuals use Form 1040-ES to calculate and pay estimated tax on income not sufficiently covered by withholding. The official 2026 package includes four payment vouchers and state-specific mailing addresses. See our 2026 Form 1040-ES guide.
Forms W-4P, W-4R, and W-4V
- W-4P: withholding from periodic pension or annuity payments.
- W-4R: withholding from nonperiodic payments and eligible rollover distributions.
- W-4V: voluntary withholding from certain government payments.
Employer and Business Forms Used in 2026
Form 941 — Employer’s Quarterly Federal Tax Return
Employers generally use Form 941 to report federal income tax withheld and employer and employee shares of Social Security and Medicare taxes. It is filed quarterly unless the employer falls under an exception or has been instructed to use another return.
Form 941-X
Use the version of Form 941-X and its instructions applicable to correcting a previously filed Form 941. Do not use Form 843 as a general substitute for amending employment tax returns.
Form 940
Form 940 reports annual Federal Unemployment Tax Act tax. FUTA is separate from the quarterly income-tax-withholding and FICA reporting on Form 941.
Forms W-2 and W-3
Employers furnish Form W-2 to employees and file wage information with the Social Security Administration. Form W-3 transmits paper Forms W-2. Scannable Copy A should not be printed from an ordinary online PDF when the IRS or SSA instructions prohibit that use.
Forms 1099 and Form 1096
The 1099 series reports different payment types, such as nonemployee compensation, interest, dividends, and retirement distributions. Form 1096 is generally a paper transmittal and is not used to transmit returns filed electronically.

Should I use a 2025 or 2026 Form 1040 when filing in 2026?
