The phrase "December 31, 2026 deadline" gets used loosely in Opportunity Zone marketing, but it means different things depending on whether you are a current OZ investor or a new one. Getting this wrong has real tax consequences. This page explains exactly what the deadline means, who it affects, and what practical steps accredited investors need to take before the window closes.

## Why December 31, 2026 Matters

December 31, 2026 is the capital gains inclusion date for all OZ 1.0 investments. Under the original 2017 Tax Cuts and Jobs Act, any gains deferred into a Qualified Opportunity Fund (QOF) are included in taxable income — and therefore become federally taxable — on December 31, 2026. This is not the day the OZ program ends. OZ 2.0, effective January 1, 2027, continues the program permanently. December 31, 2026 is specifically the day the original deferral clock runs out.

For current OZ investors who deferred gains in 2018–2021 and held for at least 5 years, a 10% step-up in basis applies — meaning you pay tax on 90% of the original deferred gain, not 100%. Either way, a real tax liability comes due on your 2026 return.

For prospective investors, December 31, 2026 marks the last date to invest under OZ 1.0 rules, and doing so positions you for the OZ 2.0 transition with a clear path to the 10-year capital gains exclusion on appreciation.

## What Happens If You Miss the December 31, 2026 Deadline

If you have recognized capital gains and do not invest in a QOF by December 31, 2026, you do not lose access to the OZ program — OZ 2.0 continues from January 1, 2027 onward. What you lose is the ability to invest under OZ 1.0 rules, which for investors with 2025 or 2026 gains primarily affects the deferral structure.

Under OZ 2.0, gains invested in a QOF after December 31, 2026 are deferred for 5 years from the investment date — a rolling window rather than a fixed December 31, 2026 endpoint. The 10-year capital gains exclusion on QOF appreciation remains available under OZ 2.0. The core economics are largely preserved; the timing mechanics shift.

That said, investing before December 31, 2026 carries a specific structural advantage: you are entering a program whose benefits have been litigated, tested, and clarified over nearly a decade, with a well-established IRS guidance framework. OZ 2.0 is permanent but still new — Treasury guidance, zone re-designations, and reporting requirements are still being developed.

## The Transition from OZ 1.0 to OZ 2.0

The transition is not a hard break — it is a handoff:

- **OZ 1.0 positions held as of January 1, 2027** retain all OZ 1.0 rules for the duration of the investment.

- **New QOF investments made after January 1, 2027** are governed by OZ 2.0 rules.

- **QOF investments made in 2026 under OZ 1.0 rules** are governed entirely by OZ 1.0. The deferred gain is included on December 31, 2026, and the 10-year appreciation exclusion is available under OZ 1.0 rules.

For sponsors managing existing OZ portfolios, the transition requires attention to zone re-designation (approximately 2,264 of the original 8,764 zones may not qualify under OZ 2.0's tighter criteria) and enhanced annual reporting requirements that kick in with the new program.

## How to Calculate Your 180-Day Window

The 180-day window begins on the date of the gain-triggering event:

**Direct asset sales (individual):**

- Sell appreciated stock on April 15, 2026 → 180-day window closes October 12, 2026

- Sell real estate on August 1, 2026 → 180-day window closes January 28, 2027 (into OZ 2.0 territory)

**Pass-through entities (K-1 holders):**

K-1 holders (partners, S-corp shareholders) have three possible start dates for the 180-day window:

1. **Date of the underlying sale** — the actual transaction date when the entity sold the asset

2. **Last day of the entity's tax year** — for calendar-year partnerships, this is December 31 of the year the gain was recognized

3. **Date the K-1 is issued** — if the K-1 is filed late, some practitioners argue the 180-day window begins when the partner receives or could reasonably have received the K-1

For calendar-year partnerships that recognized gains in 2025, electing the year-end start date gives a 180-day window closing June 28, 2026. For gains recognized in 2026, the window starts December 31, 2026 and closes June 28, 2027.

**Critical date for K-1 holders with 2025 gains:** If you elect to start the 180-day window from the date the K-1 is issued (typically March 15 for calendar-year partnerships), and your K-1 was issued on or around March 15, 2026, your 180-day window closes approximately September 11, 2026 — well before December 31, 2026.

**Straddling strategy:**

Investors with gains recognized in late 2026 (September or later) have a 180-day window that extends past December 31, 2026 into OZ 2.0 territory. This creates a structural choice: invest before December 31, 2026 under OZ 1.0 rules (accepting the immediate deferral inclusion), or wait until after January 1, 2027 and invest under OZ 2.0's rolling 5-year deferral. The right answer depends on the investor's tax position, the fund's timeline, and whether the target zone retains its OZ 2.0 designation.

**Tax character preservation:**

The character of the original gain — short-term or long-term — is preserved through the deferral. A short-term capital gain deferred into a QOF is still taxed at ordinary income rates when included on December 31, 2026. This matters because short-term gains deferred into a QOF do not convert to long-term treatment by virtue of the holding period.

## Timeline for Getting Capital Deployed

OZ investing is not a quick transaction. Institutional QOFs require subscription documents, accredited investor verification, wire instructions, and fund admission. Most sponsors need a minimum of 2–4 weeks from initial contact to funded investment. Here is a realistic timeline for an investor acting in 2026:

| Date | Action Required |

|---|---|

| Now (March 2026) | Identify and evaluate fund sponsors |

| April–June 2026 | Complete diligence, request subscription documents |

| June–September 2026 | Submit executed subscription agreement, satisfy accredited investor verification |

| October–November 2026 | Fund wire transfer, confirm QOF admission |

| December 31, 2026 | Hard deadline for OZ 1.0 investment |

**Do not wait until Q4.** Sponsors managing a December 31 deadline may impose earlier internal cutoffs to ensure proper fund documentation and IRS compliance. Savoy's 2026 QOF — targeting $15–25M with a December 31, 2026 close — is one such fund operating on this calendar. Investors who contact the fund in November may encounter a closed or fully-subscribed vehicle.

## What to Look for in a Sponsor at This Stage

In March 2026, you have approximately 10 months to identify a sponsor, complete diligence, and fund. At this stage in the program lifecycle, the field of credible OZ sponsors has narrowed considerably. Many funds that launched in 2019–2020 have wound down or are deep in the hold period. New entrants who spun up an "OZ fund" without genuine development or tax expertise are either gone or avoiding scrutiny.

What to prioritize now:

**Realized track record, not projected.** Any sponsor pitching a 2026 OZ fund should have exits from prior funds — not just a portfolio of unrealized assets. Ask for audited returns on completed projects.

**OZ-specific operational experience.** The 90% asset test, QOZB compliance, substantial improvement documentation, and QOZB-level cost segregation require hands-on experience. Ask how many tax returns the sponsor's team has prepared for QOZBs.

**Construction control.** A 10-year hold on multifamily real estate means renovation cycles, capital expenditure decisions, and operational changes will occur during the hold period. Sponsors who own their construction capability — rather than relying on third-party GCs — have more direct control over timeline, cost, and quality.

**Geographic focus with genuine market knowledge.** National OZ platforms often lack the submarket-level underwriting precision needed to buy and improve real estate in distressed census tracts. Sponsors with deep local relationships and submarket data have better acquisition discipline.

**Investor alignment.** Review the fee structure: acquisition fees, asset management fees, disposition fees, and the carried interest waterfall. High fee loads compress investor returns, especially on a 10-year hold.

## The Savoy 2026 QOF

Savoy Equity Partners is currently raising the Savoy 2026 QOF — a 506(c), accredited-investor-only fund targeting $15–25M with a December 31, 2026 close. The fund focuses on Texas multifamily in Opportunity Zones, consistent with Savoy's $92M+ of prior OZ equity deployed since the program's inception. Savoy has 58 projects, 27+ exits, and a 40.58% realized IRR across its portfolio — with zero losses.

Investors interested in the Savoy 2026 QOF should initiate contact now to ensure sufficient time for diligence and fund admission before the December 31 deadline.
