Tax season can feel overwhelming, but knowing the key dates ahead of time makes the process much easier. In 2026, taxpayers will file returns for income earned in 2025. Below is a straightforward guide to important federal tax deadlines for individuals, freelancers, and business owners.
Note: These dates apply to federal taxes only. State tax deadlines may be different.
When Does Tax Filing Start in 2026?
The Internal Revenue Service (IRS) will begin accepting and processing 2025 tax returns on January 26, 2026.
Filing early can help you:
- Receive your refund faster
- Avoid last-minute stress
- Fix any issues in time
E-filing is the quickest and safest way to submit your return.
Main Tax Filing Deadlines
Different taxpayers have different deadlines:
Multi-Member LLCs and Partnerships
March 15, 2026
Single-Member LLCs and Individual Taxpayers
April 15, 2026
By your deadline, you must:
- File your tax return
- Pay any taxes owed
- Submit your first estimated tax payment for 2026 (if required)
Requesting a Tax Extension
If you cannot file on time, you can request a free extension by April 15, 2026.
If approved, your new filing deadline will be October 15, 2026.
⚠️ Important: An extension gives you more time to file, not more time to pay. To avoid penalties and interest, you must still pay any taxes owed by April 15.
