| Opportunity Zone fund | 1031 exchange | |
|---|---|---|
| What it defers | The capital gain or Section 1231 gain you invest; ordinary recapture does not qualify | All gain, including recapture, if value and debt are fully replaced |
| What you must reinvest | Only the gain; your basis is yours to keep | All net proceeds, plus replacement of any debt paid off |
| Which gains qualify | Gain from selling almost any capital asset to an unrelated buyer: stock, a business, real estate | Gain on real property held for business or investment only |
| Deadline | Invest within 180 days of the sale (installment gain: of each payment, or of year end) | Identify in 45 days, close by 180 days, through a qualified intermediary |
| How long it defers | Investments after 2026: until the earlier of selling the fund interest or five years | Open-ended, until a taxable sale of the replacement, or never if held until death |
| Reduction of the deferred gain | 10% basis step-up at five years (30% in a qualified rural opportunity fund) | None; the full gain rides in a lower basis |
| Growth on the new investment | Excluded from federal tax if held 10 years and you elect; value fixed at year 30 at the latest | Taxable later, unless held until death |
| Who holds the money | A qualified opportunity fund that invests in zone property or businesses | You own the replacement property, directly or through a Delaware statutory trust |
| Investment control | None; you pick the fund, the sponsor runs it | Full for direct property; none in a Delaware statutory trust |
| Liquidity | Low for about ten years; tax due at year five with no distribution assumed | Low; equity stays in real estate |
| Costs and fees | Fund management, acquisition and disposition fees, promote, and any selling load | Intermediary fee, closing costs, ongoing management |
| IRS guidance status | Statute and final regulations; Notice 2026-40 bridges to the new rules; more regulations pending | Settled statute and regulations |
| State tax | California does not conform: gain is taxed at sale | Most states follow; some track out-of-state replacements |
| Estate result | Death is not an inclusion event, but the deferred gain passes to heirs with no step-up | Replacement property gets a basis step-up at death |
| Can it combine with the other? | Yes: invest boot gain from a partial 1031 within 180 days | Yes: exchange most of the value, put the boot gain in a fund |
The core difference: gain only, or everything
A 1031 exchange asks for everything. To defer all of the gain you reinvest every dollar of net proceeds and replace any debt you paid off, in more real estate, through an intermediary, on a 45-day and 180-day clock.
An Opportunity Zone investment asks only for the gain. Sell a $2,000,000 building with an $800,000 basis and you can keep the $800,000 and put just the $1,200,000 gain into a qualified opportunity fund within 180 days. The gain can come from almost any sale to an unrelated buyer: stock, a business, a building, land. Nothing has to be like-kind.
The 1031 defers longer and covers recapture. The Opportunity Zone frees your basis, accepts any capital gain, and can exclude a decade of growth from federal tax. They solve different problems.
Opportunity Zones after the One Big Beautiful Bill Act
The original program ended all deferral on December 31, 2026. The One Big Beautiful Bill Act (P.L. 119-21, Sec. 70421) made the program permanent and rewrote the rules for amounts invested after December 31, 2026:
- Five-year deferral, per investment. The gain is included in the tax year that contains the earlier of selling the fund interest or the fifth anniversary of the investment.
- 10% step-up. After five years, basis rises by 10% of the deferred gain, so 90% is taxed. In a qualified rural opportunity fund the step-up is 30%.
- A falling fund shrinks the bill. The amount included is the lesser of the deferred gain or the investment's fair market value, minus basis.
- Ten-year exclusion. Hold at least ten years and elect, and basis equals fair market value when sold, so the fund's growth escapes federal tax. For sales after year 30, value is fixed at the 30th anniversary.
- New zone map. New zones take effect January 1, 2027, for ten-year periods.
The 2026 bridge. Gain invested on or before December 31, 2026 stays under the old rules and is taxed on the 2026 return. Notice 2026-40 confirms that gain realized on, before or after December 31, 2026 and invested in 2027 or later, within its 180 days, gets the new rules. A sale late in 2026 can therefore reach the new rules by investing in early 2027.
How a 1031 exchange compares on the same sale
The exchange defers the whole gain, including depreciation recapture, with no five-year clock. Basis carries over, so the gain waits inside the replacement property until a taxable sale. If you hold until death, your heirs take a stepped-up basis and the deferred gain can disappear (Section 1014). You can also exchange again and again.
The costs are the constraints: only real property, all proceeds and debt replaced, strict deadlines, and you remain a real estate owner. If you buy a Delaware statutory trust interest to avoid management, you trade control for a passive, illiquid position with sponsor fees.
Worked example: $2,000,000 rental, two paths
Assumptions (illustrative, engine output): married couple filing jointly, $150,000 of other income, Texas, federal tax at 2026 rates in every year. Rental sold late in 2026 for $2,000,000; basis $800,000; gain $1,200,000 ($400,000 unrecaptured Section 1250 gain, no ordinary recapture). No mortgage. For comparison, a cash sale owes $314,953 of federal tax on the gain in 2026.
| Opportunity Zone fund | Full 1031 exchange | |
|---|---|---|
| Reinvested | $1,200,000 (the gain), early 2027 | $2,000,000 (all proceeds), within 180 days |
| Cash kept at closing | $800,000 | $0 |
| Tax at closing | $0 on the invested gain | $0 |
| Tax later on the original gain | About $277,841 in 2032 on $1,080,000 (90%), if the fund is worth at least the gain | Deferred until the replacement is sold; $0 if held until death |
| Growth | Excluded from federal tax after 10 years, with the election | Taxable on a later sale |
In a qualified rural opportunity fund, 70% ($840,000) would be included at year five instead of 90%. The year-five tax usually has to come from your own cash, because most funds do not distribute at that point. The $800,000 kept at closing, invested elsewhere, is one way to plan for it.
The Opportunity Zone result depends on the fund. In our engine modeling across rentals, business sales and farmland, the fund needed to earn roughly 3.6% to 4% a year after all fees, over 20 years, before it beat paying the tax and investing in an ordinary taxable portfolio. The tax benefit does not rescue a weak fund.
Using both on one sale
A partial 1031 and an Opportunity Zone fit together. Exchange most of the value into replacement property and take some cash as boot. The boot gain is recognized, and gain recognized on the sale is eligible gain, so investing that gain in a fund within 180 days can defer it again. The same works with an installment sale: each principal payment's gain can start its own 180-day window (or the window can start at year end), so a note paid over ten years can feed ten separate fund investments, each with its own five-year and ten-year clocks.
Only the gain moves into the fund. Interest on a note and ordinary depreciation recapture are not eligible.
California and other states
California does not conform to the Opportunity Zone rules, old or new: it taxes the gain when realized, does not tax it again at the federal inclusion date, and taxes the fund's growth when you sell. A California seller who invests the whole gain still owes the state tax in the sale year from other money. California follows Section 1031, and requires annual reporting when a California property is exchanged for property in another state. Other states vary; confirm your state with your CPA before relying on either deferral.
What qualifies, and what does not
For an Opportunity Zone deferral:
- The gain must be capital gain or qualified Section 1231 gain from a sale to an unrelated person. The related-party test uses a 20% ownership threshold and covers family members, so a sale to your children or your own company does not qualify.
- The investment must be equity in a qualified opportunity fund. A loan to the fund does not count.
- Only an amount equal to the gain counts; dollars invested above the gain are a separate, ordinary investment.
- You elect on Form 8949 for the year the gain would have been taxed and file Form 8997 every year after.
For a 1031 exchange:
- Both properties must be real property held for business or investment. Your home and property held mainly for resale (a flip or a developer's lots) do not qualify.
- Swaps with related parties are allowed, but if either side disposes of its property within two years, the deferral unwinds (Section 1031(f)).
- You cannot receive or control the proceeds; a qualified intermediary holds them under a written agreement.
Costs, fees and IRS footing
Opportunity Zone funds charge what private real estate charges: annual management fees, acquisition and disposition fees, a share of profits above a preferred return, and in broker-sold funds an upfront selling load. Low-cost listed vehicles exist alongside private funds with much higher layers. Ask for the all-in annual fee, the load and the promote in writing. Each fund must hold at least 90% of its assets in qualified zone property, and you file Form 8997 every year you hold the investment.
1031 exchanges cost an intermediary fee, closing costs and ongoing management, or sponsor fees in a Delaware statutory trust.
Both rest on statute and final regulations. The Opportunity Zone side is still moving: Treasury has promised investor-side regulations for the new rules, and the regulation text still recites the old 2026 cutoff, so your CPA will rely on the statute and Notice 2026-40 for investments after 2026.
Which fits which seller
Lean toward the 1031 if you want to keep owning real estate, have recapture you want deferred, and plan to hold until death for the basis step-up.
Lean toward an Opportunity Zone fund if you are selling stock, a business or anything not like-kind, you want your basis back in cash, you can leave the gain invested for ten years or more, you have cash for the year-five tax, and you have found a fund whose fees and track record you and a licensed adviser are comfortable with.
Use both when you want some real estate, some cash, and a long-term growth position. The Big Sale Tax Analysis models each combination for your numbers.
What to know
A 1031 keeps you in real estate on strict deadlines and requires replacing all proceeds and debt, but defers everything open-ended and pairs with a step-up at death. An Opportunity Zone fund defers only five years, taxes 90% (or 70% rural) of the gain at year five, usually while the fund interest is still illiquid, locks money up for about ten years to earn the growth exclusion, depends heavily on fund quality and fees, gives no step-up on the deferred gain at death, and gets no California deferral. Interest and ordinary recapture never qualify.
