Construction 1031 Exchange
Most people who ask about a construction 1031 exchange are describing a project that will not fit inside the deadline, and nobody tells them until the money is already committed.
This page is going to lead with that, because the decision you are actually making is not which exchange structure to use. It is whether your build can reach enough completed value inside 180 days to be worth doing at all.
What Is a Construction 1031 Exchange?
A construction 1031 exchange lets you use your sale proceeds to build a new property on land you are acquiring, and to count the completed construction toward the value you are required to reinvest. A third party holds title while the building goes up, and you receive the property once the work is done.
It is also called a build-to-suit exchange. Both names describe the same mechanism: an Exchange Accommodation Titleholder parks the property, construction happens, and the finished real estate transfers to you to complete your exchange.
In a standard delayed exchange, your Qualified Intermediary holds your proceeds and releases them to buy a property that already exists. Here, the proceeds buy land and pay for a building, and only the part of the building that is physically finished counts.
If you are renovating or expanding a structure that already stands rather than building from the ground up, you want the improvement 1031 exchange instead. Same legal structure, very different odds of success, for reasons the next section explains.
The Hard Part: 180 Days Is the Entire Build
Your construction window is not 180 days of construction. It is 180 days total, starting the day your relinquished property closes, and it has to absorb everything: finding and closing on land, permits, site work, foundation, vertical construction, and the transfer back to you.
On a renovation, that is usually survivable, because most of the property’s value is already standing on day one. On a ground-up build it is brutal. A project that breaks ground on day 75 and takes fourteen months to finish will be perhaps 20% complete when the clock runs out, and you will receive a partially built building valued accordingly.
The IRS does not extend this deadline. Not for permitting, not for weather, not for a supply delay, not for a contractor who walks.
What “Completed” Means on Day 180
Only work that is physically in place when you take title counts toward your exchange value. Not paid for, not ordered, not delivered. In place, incorporated into the real property, and part of the building.
That excludes several things investors assume will count:
- Funds escrowed for work scheduled after closing.
- Deposits to contractors for work not yet performed.
- Materials sitting on site but not yet installed.
- Prepaid design, engineering, or permitting fees for work still to come.
- Equipment and furnishings that stay personal property instead of becoming part of the real estate.
Whatever value is missing on day 180 is a shortfall against your reinvestment target, and the shortfall is taxable boot. On a ground-up project that number is usually large.
Why You Cannot Build on Land You Already Own
Exchange funds cannot be spent improving property you hold title to. The moment you own it, the exchange is complete as to that property, and every dollar spent after that is your own money on your own land. It increases your basis. It adds nothing to your exchange value.
So if you already own the lot you want to build on, a construction exchange is not available to you for that lot. This is the single most common disappointment on this topic, and it comes up constantly, because owning the land first feels like it should be an advantage.
What an Exchange Accommodation Titleholder Does
An Exchange Accommodation Titleholder, or EAT, is a separate legal entity that takes and holds title to the property while construction happens, then transfers the finished property to you. It exists for no other reason.
Revenue Procedure 2000-37 created the safe harbor that permits this. In practice the EAT is a single-member LLC formed for your transaction. That LLC is the entity on the deed, the borrower on any construction loan, the party to the contract with your general contractor, and the named insured. The written agreement establishing it must be signed no later than five business days after title transfers to it.
The EAT cannot be you, your agent, your attorney, your accountant, or any other disqualified person under the regulations. It has to be genuinely independent, which is why this is not a structure you can improvise with an LLC of your own.
The Reverse Construction Exchange, and What It Actually Buys You
It does not give you more than 180 days. Anyone who tells you otherwise is wrong, and this is worth being blunt about because the claim circulates widely. Revenue Procedure 2000-37 caps the combined time that the relinquished and replacement properties can sit in a parking arrangement at 180 days. Reversing the order does not reset that.
What it does buy you is where those 180 days go.
In a forward construction exchange, your clock starts when your relinquished property sells, and you then have to find land, close on it, and mobilize. Thirty to sixty days can disappear before anyone pours concrete. In a reverse construction exchange, the EAT acquires and parks the land first, construction begins immediately, and you sell the relinquished property afterward. Every one of your 180 days is a construction day, and you control the timing of the sale instead of racing a date somebody else set.
On a ground-up project that difference is frequently the difference between a workable deal and a large tax bill. It is not a loophole, and it is not more time. It is the same time, spent building instead of shopping.
How a Construction 1031 Exchange Works, Step by Step
- Engage your intermediary before your sale closes. Once proceeds reach you, nothing can be structured. This is not a preference, it is the whole game.
- Have the land, the plans, the permits and the lender lined up first. Every day spent arranging these after your sale closes is a day taken out of your build.
- Sell the relinquished property. Proceeds go to the Qualified Intermediary.
- The EAT acquires the land, funded by exchange proceeds and any construction loan made to the EAT entity.
- Identify in writing within 45 days, naming the property and describing the improvements you intend to make in as much detail as is practicable. Plans and specifications belong in that identification.
- Construction runs while the EAT holds title. Exchange funds are released against work actually performed, not held for future work.
- The property transfers to you on completion or on day 180, whichever comes first.
- The exchange is reported on Form 8824 at the value of the real property actually received.
Construction Exchange vs. Improvement Exchange
| Construction exchange | Improvement exchange | |
|---|---|---|
| Starting point | Land you are acquiring | An existing building you are acquiring |
| Typical work | Ground-up vertical construction | Renovation, system replacement, tenant improvements, expansion |
| Value in place on day one | Land only | Substantial |
| Odds of full deferral in 180 days | Low unless permits are already in hand and the build is fast | Good |
| Where the risk sits | Completion. Most of your value has to be created inside the window | Scope. The gap you are closing is usually modest |
Same legal structure, opposite risk profile. If the building already stands, you want the improvement 1031 exchange.
When a Construction Exchange Is the Wrong Tool
Marcus’s deal works because storage is fast to build and he had land, plans and a lender ready before he sold. Change any one of those and the math collapses.
A construction exchange is usually the wrong tool when:
- You do not yet have entitlements or permits. Anything discretionary can consume your entire window on its own.
- The build is long. Multifamily, hospitality, and anything with significant sitework rarely gets far enough inside 180 days to justify the added cost and risk.
- You already own the land. Not a timing problem, a structural one. See above.
- Your lender will not lend to the EAT entity. Many will not, and discovering this in week six can end the deal.
- The tax at stake is modest. A construction exchange carries real cost. On a small gain it is not worth it.
When it is the wrong tool, the alternatives are ordinary and often better. Buy a property that already exists and meets your number. Run a deliberate partial exchange with the boot planned for rather than discovered. Use a Delaware Statutory Trust to absorb proceeds you cannot otherwise place inside the window. Or read what happens when an exchange fails and decide whether the deferral was ever the point.
We would rather tell you this before you sell than after.
A Worked Example
Marcus sells an industrial building for $3,000,000. His adjusted basis is $1,100,000 and selling costs are $180,000, so $2,820,000 goes to the Qualified Intermediary and his realized gain is $1,720,000. To defer all of it he needs to acquire replacement real property worth at least $2,820,000.
He wants to build self storage. Land is $800,000, the building is $2,400,000, and his contractor says fourteen months.
As a forward construction exchange. He sells, then spends five weeks finding and closing on the land. Site work and foundation take until day 75. By day 180 roughly $640,000 of construction is physically in place. He receives land plus completed work worth $1,440,000 against a $2,820,000 target, leaving $1,380,000 of boot. At a combined 28.35% federal and Utah rate that is roughly $391,000 in tax, before any depreciation recapture.
As a reverse construction exchange. The EAT acquires and parks the land before he sells. Construction starts on day one instead of day 75. He times the sale of the industrial building so the 180 days are spent building. By transfer, roughly $1,600,000 of work is in place. He receives $2,400,000 of real property, leaving $420,000 of boot and about $119,000 in tax.
The reverse structure did not buy Marcus a single extra day. It moved roughly $960,000 from the taxable column to the deferred column, worth about $272,000, purely by spending his 180 days on construction rather than on land shopping.
And he still owes tax on $420,000. That is the honest outcome on a fourteen-month build, and it is why the next section exists.
What a Construction Exchange Costs
Budget for more than the exchange fee.
- Accommodation fees for forming the EAT and administering the parking arrangement.
- Two closings. Title, escrow and recording when the EAT acquires, and again when it transfers to you.
- Transfer taxes, potentially twice, depending on jurisdiction. On a multimillion dollar parcel this is a real number and should be confirmed before you commit.
- Carrying costs during the parking period. Property taxes, insurance, builder’s risk coverage, and liability on a property the EAT holds.
- Construction financing to the EAT entity rather than to you. Expect the lender to want a personal guarantee, and expect the conversation to take longer than you think.
Frequently Asked Questions
Can I use a 1031 exchange to build on land I already own?
No. Exchange funds cannot improve property you already hold title to. The land has to be acquired as part of the exchange and held by an Exchange Accommodation Titleholder while construction happens. Owning the lot beforehand disqualifies it, which surprises most investors.
How long do I have to finish construction?
The building must be physically in place by the time you take title, and no later than 180 days after your relinquished property closes. The deadline is statutory. The IRS does not extend it for permitting, weather, supply delays, or contractor default.
Does a reverse construction exchange give me more than 180 days?
No. Revenue Procedure 2000-37 caps the combined parking period at 180 days regardless of which property is parked first. What the reverse structure changes is how those days are spent: construction can begin before your sale closes, rather than after you find and close on land.
What happens if the building is not finished on day 180?
You take title to whatever exists. Only completed, installed work counts toward your reinvestment requirement, and the shortfall becomes taxable boot. On a ground-up project the shortfall is often large, which is why the build timeline should drive the decision.
Is a construction exchange the same as a build-to-suit exchange?
Yes. Construction exchange and build-to-suit exchange describe the same structure under the same IRS guidance. An improvement exchange uses that structure too, on a building that already stands rather than on raw land.
Can I do a construction exchange on leased land?
Sometimes. A leasehold with 30 years or more remaining is treated as like-kind to a fee interest in real property, which opens a narrow path for building on ground-leased land. The details matter and related-party leases invite scrutiny. Our article on leasehold interests in 1031 exchanges covers the 30-year rule in full.
