The short answer
The real estate qualifies and almost nothing else in the deal does. Section 1031(a)(1) covers real property held for productive use in a trade or business, so the building your own company occupied is exchangeable even though you never had a tenant in it. Goodwill, the covenant not to compete and the machines on the floor are separate assets under the section 1060 residual method, and the tax on those is due with the return for the year you close. Settle the allocation schedule and the exchange at the same time, because the number written next to the real estate is the only number that can be rolled forward.
At a glance
| Qualifying use | §1031(a)(1): real property held for productive use in a trade or business |
|---|---|
| Allocation method | §1060 residual method, seven asset classes, reported on Form 8594 |
| Form 8594 exception | Not filed for assets covered by §1031; still filed for the rest |
| Equipment | §1245 gain is ordinary; §1245(b)(4) caps it at recognized gain plus non-1245 FMV |
| Covenant not to compete | A §197 intangible: ordinary income to you, amortized by the buyer over 15 years |
| Incidental personal property | Reg. §1.1031(k)-1(g)(7)(iii): under 15% of replacement value, still taxable boot |
| Leaseback ceiling | Reg. §1.1031(a)-1(c)(2): a leasehold with 30 or more years to run is like-kind to a fee |
Draw the allocation schedule before you agree a price, because one line of it is exchangeable
A business sale that carries real estate is an applicable asset acquisition, and both sides must spread the consideration across seven classes by the residual method set out in the Form 8594 instructions. Land, the building, furniture and equipment all land in Class V; the covenant not to compete and other section 197 intangibles land in Class VI; goodwill and going-concern value take whatever is left in Class VII.
Inside Class V, only the land and the building are real property under Reg. §1.1031(a)-3, which defines real property as land, improvements to land, unsevered natural products and the air and water space above. That definition, not your appraiser's opinion of the going concern, sets the ceiling on what the qualified intermediary can hold.
The instructions waive Form 8594 for the assets that pass through a section 1031 exchange while still requiring the form for everything else. Two reporting tracks out of one closing is normal here, and it is the clearest signal that the IRS expects the halves to be priced separately.
- Class V: land, building, site improvements, furniture, fixtures, vehicles and equipment.
- Class VI: covenants not to compete, customer lists, trade names and other section 197 intangibles.
- Class VII: goodwill and going-concern value, which absorb the residual and cannot be exchanged.
- A consulting or employment agreement signed at closing is compensation, not sale proceeds.
Worked example: a $3,000,000 practice sale where $2,000,000 rolls forward and $1,000,000 does not
Take a hypothetical clinic sold for $3,000,000 with round numbers. The parties agree on $2,000,000 for the land and building, $400,000 for equipment, $150,000 for a five-year covenant not to compete and $450,000 of residual goodwill.
The building cost $1,200,000 twenty years ago and $500,000 of depreciation has been claimed, leaving an adjusted basis of $700,000. Exchanging the whole $2,000,000 of real estate defers $1,300,000 of gain and carries the $700,000 basis into the replacement.
The other $1,000,000 is settled this year. Fully depreciated equipment produces $400,000 of ordinary income under section 1245, the covenant produces $150,000 of ordinary income while the buyer amortizes it over fifteen years under §197(a), and the $450,000 of goodwill is capital gain with no exchange available. Confirm every figure with your own CPA or attorney before you sign; these are illustrations, not advice.
A cost segregation study makes the building cheaper to own and more expensive to trade
If an engineer carved your building into five- and fifteen-year components, some of what you are selling is section 1245 property even though all of it is real property for exchange purposes. Reg. §1.1031(a)-3(a)(7) says so directly: a structure or a portion of a structure may be section 1245 property for depreciation and for determining gain under section 1245 even while it is real property under the exchange rules.
The cost shows up through §1245(b)(4), which caps the ordinary income at the gain you recognize plus the fair market value of any acquired property that is not itself section 1245 property. Swap a cost-segregated clinic for a bare parcel of ground and the accelerated deductions come back as ordinary income even though the exchange itself is clean.
The practical fix is to look for replacement property that carries its own depreciable components, and to ask the study's preparer for the section 1245 balance before you market the building rather than after the closing statement is drafted.
The chairs and the phone system are incidental for the safe harbor and taxable anyway
Buyers of small commercial buildings usually take the furniture with the walls. Reg. §1.1031(k)-1(g)(7)(iii) treats personal property as incidental, and so ignores it for the restriction on your access to funds, when it is typically transferred with the real estate and is worth no more than 15 percent of the replacement real estate.
Incidental does not mean tax free. Example 6 in that regulation has a taxpayer receive a $1,000,000 office building plus $100,000 of office furniture and recognize $100,000 of gain under section 1031(b), because the furniture is not like-kind property.
So the 15 percent test protects the structure of the exchange, not the tax result. If you want the replacement's contents without a bill, negotiate them into a separate purchase paid with cash that never enters the exchange account.
Staying in the building for a few more years means watching the thirty-year line on the leaseback
Many owners sell the real estate, keep operating and rent the space back from the new landlord. That works with an exchange, but the lease term matters: Reg. §1.1031(a)-1(c)(2) treats a leasehold of a fee with 30 years or more to run as like-kind to real estate.
A leaseback long enough to cross that line is itself a real property interest coming back to you, which invites the argument that you exchanged rather than sold. Keeping the initial term plus all renewal options under thirty years is the ordinary way transaction counsel avoids the question.
If the buyer is a family member or an entity you control, §1031(f) adds a second problem: a disposition by either side within two years of the exchange unwinds the nonrecognition. When the building sits inside your operating corporation rather than beside it, start with 1031 exchange strategies for properties owned in S-corps and C-corps.
Where the $2,000,000 goes, and what we do once the letter of intent exists
Replacement options for an exiting operator fall into three shapes: a net-leased building you own outright, fractional interests through a traditional DST or a direct title security, or a mix that spreads the equity across tenants and regions. The 1031 eligibility requirements apply the same way to all three.
Breakwater Exchange places 1031 replacement property: more than twenty years in the work, over a billion dollars of DST transactions, licensed in all 50 states inside a regulated broker-dealer framework, and working only with vetted national DST sponsors. We are not your qualified intermediary and not your accountant.
What we can do is size the replacement to the real estate line of the allocation schedule while your attorney is still negotiating the covenant and the goodwill, so the 45-day clock opens with a shortlist already underwritten. The website form is the only way to reach us.
Related questions
I never rented the building to anyone. Does that disqualify it?
No. Section 1031(a)(1) reaches real property held for productive use in a trade or business as well as property held for investment, and a building your own company operated in is the classic example of the first category.
Can I put the goodwill into the exchange if the buyer agrees to call it real estate?
No. The allocation must reflect fair market value under the residual method, both sides file consistent statements, and mispricing the real estate to shelter goodwill invites a deficiency on the very gain you were trying to defer.
The buyer wants to pay me over five years. Does that break the exchange?
Not necessarily, but the note is not like-kind property. The pieces you carry become installment gain while the cash portion can still be exchanged, so decide the split before the purchase agreement is signed.
What if the building is worth more than I need to reinvest?
You can take some proceeds as intentional boot and exchange the rest; the cash is taxable and the remainder stays deferred. Intentional boot in a 1031 walks through sizing the cash.
Does the exchange have to close before the business sale?
No, but the relinquished real estate must be transferred through the qualified intermediary, which means the intermediary's documents have to exist before that closing rather than after it.
