IRS Form 1065 (2025): Instructions, PDF Download & Schedule K-1 Guide

IRS Form 1065 (2025) – Filing IRS Form 1065 for tax year 2025 is required for most partnerships to report income, deductions, credits, and other items that pass through to partners. The partnership itself pays no income tax — partners report their shares on their individual returns via Schedule K-1 (Form 1065).

This 2026 guide covers everything you need: official PDF downloads, who must file, exact due dates, e-filing rules, step-by-step instructions, Schedule K-1 reporting details, what’s new for 2025, and common pitfalls. All information comes directly from current IRS sources as of March 2026.

What Is IRS Form 1065?

Form 1065, U.S. Return of Partnership Income, is an information return (not a tax return). Partnerships report:

  • Ordinary business income/loss
  • Rental/real estate income
  • Interest, dividends, capital gains
  • Deductions (salaries, depreciation, section 179)
  • Credits, self-employment earnings, foreign items, and more

Partners receive Schedule K-1 showing their distributive share. The current version is Form 1065 for tax year 2025 (calendar year 2025 or fiscal years beginning in 2025).

Who Must File Form 1065 in 2026?

Every domestic partnership must file unless it has no income and no deductible expenditures. This includes:

  • General partnerships
  • Limited partnerships
  • LLCs taxed as partnerships
  • LLPs

Exceptions (no Form 1065 required):

  • Qualified joint ventures (spouses elect out)
  • Certain syndicates electing under §761(a)
  • REMICs (file Form 1066)
  • Publicly traded partnerships taxed as corporations (file Form 1120)

Foreign partnerships file only if they have U.S. effectively connected income or meet other U.S.-source thresholds. Qualified Opportunity Funds must file and attach Form 8996 even with no activity.
