Tax season 2026 does not have an official IRS start date yet, but most signs point to a late January or possibly mid‑February 2026 start, with final confirmation expected in early January 2026.

What “tax season 2026” means

  • “Tax season 2026” is when the IRS starts accepting and processing 2025 federal income tax returns and runs through the April 15, 2026 deadline for most filers.
  • In recent years, the IRS has opened in late January (for example, January 27 in 2025), which is why most guidance still describes tax season as starting in late January.

What we know so far for 2026

  • A new IRS commissioner publicly suggested that 2026 filing could begin around Presidents Day (February 16, 2026) , which would be roughly a three‑week delay versus a typical late‑January opening.
  • After that comment, the IRS emphasized that no official date has been set and that the timing will be formally announced closer to January 2026.

Practical timeline to expect

  • Probable window: somewhere between late January 2026 and mid‑February 2026 , depending on whether the IRS follows its usual pattern or opts for a delayed opening.
  • The IRS typically issues a press release in early January with the exact opening date (for 2025, the announcement came January 10 and the opening was January 27).

Key 2026 dates that are already set

Even though the opening date is still TBD, some core 2026 tax dates are already on the calendar:

  • April 15, 2026 – Regular deadline for individual 2025 federal income tax returns and first 2026 estimated payment.
  • Jan. 31, 2026 – General deadline for employers to send W‑2s ; many 1099s are due around the same time.
  • Oct. 15, 2026 – Extended filing deadline if you request an extension for your 2025 return.

Quick Scoop (forum / trending angle)

On tax forums and in professional circles, the big trending topic is whether tax season 2026 will really slip to mid‑February , which would:

  • Delay early filers’ refunds by a few weeks.
  • Compress the busy season for tax pros into a shorter, more intense window.

Some tax pros are already advising clients to:

  1. Gather income forms (W‑2s, 1099s, etc.) as soon as they arrive.
  2. Let their preparer pre‑load information so the return can be e‑filed quickly once the IRS opens.
  3. Expect that if the IRS does shift to a mid‑February start, early February refunds will likely move into late February or March.

Bottom line: until the official IRS announcement in early January 2026, “tax season 2026 when will it start” has a tentative answer—late January or mid‑February 2026, with mid‑February being heavily rumored but not guaranteed.
