OZ K-1 Guide

Change note: Corrected pass-through timing, basis, and loss limitations.

Key Takeaways

  • An OZ K-1 differs from a standard real estate K-1 because the investor's initial tax basis is $0 (not the amount invested), with basis provided through qualified non-recourse debt allocation.
  • Well-prepared OZ K-1s include 5-8 pages of notes explaining the zero basis, debt allocations, and step-up tracking. A short K-1 from an OZ fund is a warning sign.
  • Generalist CPAs commonly panic over the $0 basis, give wrong advice on the 25% depreciation recapture rate (which is eliminated in a qualifying 10-year OZ exit), and miss K-1 timing elections (e.g., March 15 start date) that could qualify the investor for OZ 2.0.

How Is an OZ K-1 Different?

A Schedule K-1 can report partnership items, debt allocations, basis information, and other facts relevant to a QOF investor. Receipt of the K-1 is not the start of an Opportunity Zone investment period. The relevant date depends on recognition, the entity's action, and any election available to the owner.

Establish the gain period first

If a partnership or S corporation has not deferred eligible gain, Treas. Reg. section 1.1400Z2(a)-1(c)(8)(iii) generally allows an owner to use the entity's tax-year end, or elect the entity gain-period start or actual unextended return due date. Use the actual fiscal year and return due date. Do not assume March 15 for every entity.

A calendar-year entity year-end of December 31, 2026 has a raw calendar 180th day of June 28, 2027. If March 15, 2027 is the entity's actual unextended due date and that election is available, its raw calendar 180th day is September 10, 2027. The selected start date is day one.

Basis, debt, and losses

An investor's outside basis is not always equal to contributed cash or equity value. Allocated partnership liabilities can increase outside basis. Depreciation and allocated losses can reduce it while debt remains allocated.

A loss shown on a K-1 is not automatically deductible and does not automatically offset wages or stock gains. Basis limitations, at-risk rules, passive-activity rules, and other taxpayer-specific limits may apply. IRS Publications 541 and 925 provide general federal guidance, but the investor's records and return control the actual result.
