Selling Your Machine Shop Without Giving 37% to the IRS

Good. You spent thirty years building tolerances and a customer list they can't replicate. Now they want to buy it.

Here's the trap: a lump-sum cash close hands 34-40% of your proceeds to the IRS the year you sell. It stacks — capital gain on the land and building, plus depreciation recapture across every machine you've bought since Reagan.

IRC §453 spreads that gain across years instead of eating it all at once. Less tax. More compounding. On your timeline.

> ### What you CAN defer vs what you CAN'T > > CAN defer (spread over years): > - The land + shop building gain — §1250 real property > - Business goodwill, customer contracts, AS9100/ITAR certification value > > CAN'T defer (taxed year one — I won't pretend otherwise): > - The equipment: CNC machining centers, lathes, mills, EDM, grinders, CMM/inspection gear, tooling. That's §1245 personal property. Ordinary-income recapture, due in full the year you close. > > The move: allocate the purchase price so as little as possible lands on §1245. In an equipment-heavy shop that line item is huge — and it's the difference between a clean deferral and a seven-figure surprise.

The math — $2.5M machine shop sale, 22-year hold

Assumptions: $2.5M combined sale (real estate + business), ~$400K basis after 22 years of accumulated depreciation. §1250 gain spreads under §453; §1245 equipment recapture is taxed year one either way.

Seller financing — without the risk

A normal installment sale means you finance the buyer. They miss payments, your money's gone — on a shop you no longer run and can't fix.

§453 flips it.

A Fortune 500-rated life carrier — Pacific Life, MetLife — holds the note and cuts your payments. Not the buyer. The carrier.

• You get the tax-spreading of seller financing.
• You carry zero buyer default risk.
• The PE roll-up over-levers and blows up in year three? Doesn't touch you. Your money already left with the carrier at closing.

Tax-smart payments, backed by an insurance giant — not the acquirer who just loaded your shop with debt.

Machine-shop-specific wrinkles

1. §1245 equipment is your biggest exposure — allocate carefully. A working shop is millions in CNC centers, multi-axis mills, Swiss lathes, wire and sinker EDM, surface and cylindrical grinders, CMMs and inspection gear, plus tooling and fixtures. All §1245, all ordinary-income recapture, none deferrable. The purchase agreement's allocation between equipment, real estate, and goodwill is the whole ballgame — negotiate it before you sign, not after.
2. Certifications are goodwill — and they're valuable. AS9100, ISO 9001, Nadcap, and active ITAR registration are why a strategic buyer pays a premium. That value lands in goodwill, which is deferrable under §453. Get it carved out and priced instead of leaving it buried in equipment.
3. Customer concentration cuts both ways. If two aerospace primes are 70% of revenue, that concentration drags your multiple down — but long-term contracts and sole-source part numbers push goodwill up. The mix drives both your price and your allocation. Get it right first.
4. You almost certainly own the building AND the business. Most long-tenured shop owners hold the real estate in one entity and the operating company in another. That's two taxable events — going-concern gain and real-property gain. Both are structurable under §453, but each needs its own allocation and its own paperwork.
5. Boomer owner-operators retiring is the whole market right now. Consolidators know the average precision-shop owner is in his 60s with no succession plan. That's leverage for you on price — and a reason to have the tax structure built before the LOI, not scrambled together at closing.
6. Work-in-process and raw stock is ordinary income. Bar stock, castings, and jobs on the floor sell as inventory — ordinary income, not capital gain, not deferrable. Price it separately so it doesn't muddy the capital-gain allocation §453 depends on.
7. Section 179 and bonus depreciation come back to bite. If you expensed machines under §179 or bonus depreciation to zero out taxes in good years, your basis in that equipment is near nothing — so nearly the entire sale price on it recaptures as ordinary income. That's not a reason to panic; it's a reason to know the number before you negotiate the allocation, so you're not surprised at closing by how much of the deal is §1245.
8. The deferral runs on your retirement timeline, not the buyer's calendar. A shop owner who takes $2.5M in one check gets pushed into the top bracket for a single year, then watches the after-tax remainder sit in a brokerage account. Spreading the §1250 and goodwill gain across 5, 10, or more years can keep you in lower brackets and let the untaxed principal keep compounding inside the carrier's note. For an owner-operator funding a 25-year retirement, that structure is often worth more than squeezing the last few points out of the sale price.

When this fits

• $1.5M+ combined sale (carrier minimums)
• 10+ year hold (real recapture exposure on aging equipment)
• Cashing out of the shop entirely (no §1031)
• Strategic or PE buyer (aerospace-defense supplier, precision roll-up, contract-manufacturing consolidator)

When it doesn't

• 1031 into another industrial building
• Sale under $1.5M
• Deal that's almost entirely equipment with little land, building, or goodwill to defer

Frequently asked

Q: Most of my value is in the machines. Can §453 defer the equipment gain? A: No. CNC centers, lathes, mills, EDM, grinders, CMMs, and tooling are §1245 personal property — recaptured as ordinary income in the year of sale and not deferrable. §453 defers the §1250 building gain and the capital gain on the land and goodwill. That's exactly why the price allocation matters so much in an equipment-heavy shop: every dollar you can defensibly move off §1245 and onto real estate or goodwill is a dollar you can spread.

Q: My AS9100 and ITAR registration are a big part of why the buyer wants us. Where does that value land? A: In goodwill — and goodwill is deferrable under §453. Certifications, qualified processes, sole-source part numbers, and long-term supplier agreements are intangible going-concern value, not equipment. Carve them out and price them explicitly in the purchase agreement so they aren't swept into the §1245 equipment bucket, where they'd be taxed year one.

Q: I own the building in an LLC and the shop in an S-corp. Do I need two structures? A: Effectively yes. Selling both triggers two taxable events — the real property and the going concern. Each can be structured under §453, but each needs its own allocation and paperwork. I handle both together so the timing and the payment streams line up instead of fighting each other.

Q: Two aerospace primes are most of my revenue. Does that kill the deal or the deferral? A: Neither, but it shapes both. Heavy customer concentration usually trims the multiple a buyer will pay, while long-term contracts and sole-source status add goodwill. §453 doesn't care about concentration — it cares about how much of the sale is deferrable capital gain versus year-one equipment recapture. We size the structure to the real allocation once the buyer's numbers are on the table.

Q: What about the bar stock, castings, and jobs on the floor? A: Work-in-process and raw inventory sell as ordinary income — not capital gain, and not deferrable under §453. Price inventory separately in the deal so it doesn't contaminate the capital-gain allocation the deferral runs on. It's a small piece for most shops, but getting it in its own line keeps the §453 portion clean.
