The extended due date for a 2023 Form 1041 (calendar‑year estate or trust that properly filed an extension) was October 15, 2024.

Quick Scoop

  • Form 1041 for a calendar‑year estate or trust is normally due April 15 of the following year, so 2023 returns were due April 15, 2024.
  • By filing Form 7004, estates and trusts can get an automatic extension of time to file, which pushes the deadline out several months.
  • For 2023 estate/trust returns on extension, the final federal filing deadline aligned with other extended 2023 returns: October 15, 2024.

How the dates line up

  1. Original due date (2023 Form 1041)
    • Calendar‑year trusts/estates: April 15, 2024.
  1. Extension mechanics
    • Extension requested via Form 7004 (Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns).
 * This provides additional time beyond the original April 15 due date to **file** (but not to pay) the tax.
  1. Final extended deadline for 2023 Form 1041
    • Guidance for 2023 extended returns indicates that the final deadline for estate/trust (Form 1041) filings on extension fell on October 15, 2024, along with extended individual and C‑corporation returns.

Always remember: an extension to file is not an extension to pay. Any 2023 Form 1041 tax owed was still due by April 15, 2024, to avoid interest and late‑payment penalties.
