1031 Exchange vs DST vs Opportunity Zone Fund: Which Fits Your Sale?

When you sell an investment property at a gain, there are three common ways to put off the tax: a 1031 exchange into another property, a Delaware statutory trust (DST) interest bought through a 1031, or an investment in a Qualified Opportunity Fund. They work differently, and the right choice depends on your numbers.

The free 1031 vs DST vs Opportunity Zone calculator puts all three side by side on the same gain, alongside a fourth path: pay the tax now and invest the rest.

What you enter

Your capital gain, your state, how many years you plan to hold, an annual return, and whether you would use a rural fund (30% step-up instead of 10%).

What it compares

Pay the tax now

Tax on the gain today, the after-tax amount grows, and appreciation is taxed at sale.

1031 exchange

Full deferral, with the deferred gain and appreciation taxed when you sell.

DST through a 1031

The tax result matches the 1031 row, because a DST interest can be like-kind replacement property. The page notes that sponsor fees and loads, which lower returns, are not modeled.

OZ 2.0 investment

The deferred gain is taxed in year 5 after the step-up, and the fund's appreciation is excluded after 10 years. The OZ math matches the site's main tax calculator.

Read the assumptions

The page is clear about its limits. It models only the gain on every path so the results are comparable. A real 1031 requires reinvesting the full sale proceeds into like-kind real property; a QOF needs only the gain. State conformity to OZ rules varies. The tool also includes a 1031 boot check. For background, read the 1031 exchange vs Opportunity Zone guide.

Can you 1031 into an Opportunity Zone?

Not directly. The OZI 1031 guide explains that a QOF interest is stock or a partnership interest, not like-kind real property, so it cannot be 1031 replacement property. What you can do is invest recognized gain, such as 1031 boot or gain from a failed exchange, in a Qualified Opportunity Fund within 180 days. That is why the tool includes a boot check.

Step by step: running the comparison

1. Open the 1031 exchange vs Opportunity Zone vs DST tool.
2. Enter your capital gain and pick your state.
3. Choose a hold period and an assumed annual return.
4. Tick the rural fund box only for a qualified rural fund.
5. Read the four rows, then read the assumptions underneath. They matter.
6. If you expect boot from an exchange, run the boot check.

Hypothetical example: splitting a sale

Hypothetical example, for illustration only. An owner sells a luxury rental and buys a replacement property for less than the sale price, leaving some cash out of the exchange. That cash is boot and is taxable. Rather than pay tax on it, the owner could invest the recognized gain in a QOF within 180 days, while the rest of the proceeds stay in the 1031. The OZI guide calls this "using both."

Quick rules of thumb from the OZI guide

• Lean 1031 if you are selling investment real estate, want to keep owning real estate, and want indefinite deferral.
• Lean Opportunity Zone if your gain is not from real estate, you want a defined exit with the 10-year benefit, or you want to move out of direct ownership into a fund.
• Use both for a large gain, or to absorb boot.

Who uses it

Owners of investment property, family offices with real estate portfolios, and agents whose clients ask "should I just do a 1031?"

Common mistakes

• Comparing the wrong amounts. A 1031 needs the full proceeds reinvested; a QOF needs only the gain. The tool models gain only so the rows compare fairly.
• Ignoring DST fees. Sponsor fees and loads are not modeled.
• Assuming a primary residence qualifies for a 1031. It is for property held for investment or business use.

Questions to bring to your CPA or adviser

The tool gives you a starting point. Before you act, these are worth asking:

• Is my property held for investment or business use, so that a 1031 is available at all?
• Do I want to keep owning real estate directly, or move into a fund?
• If I do a 1031, how much boot do I expect, and could that gain go into a QOF?
• What fees would a DST sponsor charge, and how do they change the comparison?
• Does my state tax the deferred gain differently under each path?
• Which path fits my estate plan?

Where this fits for luxury sellers and buyers

Owners of luxury rentals and small portfolios often default to a 1031 because it is familiar. But a 1031 locks your full proceeds into more real estate, and the replacement deadlines are tight. An Opportunity Zone fund only needs the gain, which can free up the rest of the cash. Running all three paths gives you a better conversation with your CPA and your agent.
