US 2025 Tax Schedule 2-21-26

For most individuals, 2025 federal income taxes are due by April 15, 2026. This deadline applies to filing Form 1040 and paying any taxes owed for the 2025 calendar year. Filing an extension allows until October 15, 2026, to file paperwork, but tax payments must still be made by April 15.  

Key 2025 Tax Deadlines (Tax Year 2025, filed in 2026):

Tax Season Opens: January 26, 2026 (IRS begins processing).

Filing Deadline: April 15, 2026.

Key Deadlines for 2025 Tax Year

Important Notes on Extensions and Payments

Extension to File ≠ Extension to Pay: Filing for an extension gives you until October 15, 2026, to submit your paperwork, but it does not grant extra time to pay. You must still estimate and pay any taxes owed by the April 15 deadline to avoid late-payment penalties.

Disaster Relief: Taxpayers in FEMA-designated disaster areas may be granted additional time beyond the standard April deadline.

State Taxes: While most states align with the federal April 15 deadline, some differ. For example, 2025 state returns are due April 20 in Oklahoma, April 30 in Delaware, and May 1 in Virginia.
