when does tax season end
Tax season in the U.S. generally ends on Tax Day, which for the current filing season is April 15, 2026, for most individual federal returns.
Key dates for this tax season
- Start of tax season (IRS begins processing returns): January 26, 2026.
- Regular federal filing deadline (Tax Day): April 15, 2026.
- Extended deadline if you file Form 4868: October 15, 2026.
So in everyday terms, “tax season” is the window from late January (when the IRS opens e‑filing) until April 15, with an optional extension to October 15 if you formally request more time to file (but you still must pay what you owe by April 15).
| Phase | What it means | 2026 date (U.S. federal) |
|---|---|---|
| Season opens | IRS starts accepting 2025 returns | Jan 26, 2026 | [9][1][3]
| Normal end of tax season | Last day to file and pay without extension | Apr 15, 2026 | [1][3][5][7]
| Extended deadline | Last day to file if you requested an extension | Oct 15, 2026 | [3][4][7][1]
If you’re reading forum discussions or “latest news” on this, people will usually mean “tax season ends” = “Tax Day,” unless they’re specifically talking about having filed an extension.
TL;DR: For most people, tax season ends April 15, 2026, but with an approved extension you can file as late as October 15, 2026 (though any tax owed is still due by April 15).
