When you sell a piece of business equipment, like a CNC machine, for more than its depreciated tax basis, the depreciation you previously deducted can be "recaptured" and taxed back, often as ordinary income rather than at the lower long-term capital-gains rate. That is the whole concept in one sentence. You took deductions over the years you owned the machine, and selling above what is left on the books can hand part of that benefit back to the IRS.
This is general information, not tax advice, and you should confirm the specifics with your own CPA or tax professional. Jason Puuri runs acquisition at MTE and has bought machines from many sellers who almost always check the tax side with their own accountant once they have a real sale number in hand.
That is the practical point. The first thing you need before any tax conversation is a real market number for the machine, and MTE gives that for free. If you want the bigger picture on the sale itself, here is how to sell a used CNC machine start to finish. Call 800-822-9524 or get a free quote.
What Depreciation Recapture Actually Is
Depreciation recapture is a tax rule that applies when you sell business equipment for more than its adjusted tax basis, taxing the portion of the gain that matches the depreciation you previously deducted as ordinary income instead of at the lower capital-gains rate.
Here is the plain-English version. Over the years you owned the machine, you deducted its cost a piece at a time. That is depreciation, and it lowered your taxable income in those years, which is the whole reason the deduction is valuable. When you go to sell, the IRS looks at what accountants call your "adjusted basis," which is roughly what you originally paid minus the depreciation you already took.
If you sell for more than that adjusted basis, you have a gain. The portion of that gain up to the depreciation you deducted is "recaptured." Instead of being taxed at the lower capital-gains rate, that recaptured piece is generally taxed as ordinary income. In plain terms, the deduction that helped you in earlier years gets partly handed back when you sell.
Equipment like a CNC machine falls under what the tax code calls "Section 1245 property," which is the category for machinery and equipment rather than real estate. That is the term your accountant may use. The mechanism is what matters here, not the code. This page explains the concept so you can have an informed conversation with your CPA, who runs the actual numbers for your situation.
Why This Is NOT the Same as Your Machine Losing Value
Depreciation recapture is a tax event about the deduction you took, while a machine losing value over time is a separate economic thing, how much it is worth on the used market as it ages, and the two share only the word "depreciation."
This is the part almost everyone mixes up, and getting it straight is the most useful thing on this page. There are two different "depreciations" in play, and they are not the same idea.
The first is market depreciation. That is your machine losing resale value as it ages, an economic concept. It is about what the used market will pay for the machine today versus what it would have paid years ago. For the full read on that side, here is how a CNC machine loses and holds value over time.
The second is depreciation recapture. That is a tax treatment of the deduction you already took, triggered only when you sell above your adjusted basis. It has nothing to do with the used market and everything to do with your tax return.
Here is where the two collide. A machine can be worth far more on the used market than its book value, because accounting depreciation drives the book number toward zero on a schedule that has nothing to do with what a buyer will actually pay. That gap, between the low book value and the real market price, is exactly what can create a recapture event when you sell. The machine is worth real money, and selling it for that money is good, but the tax math runs off the gap. Knowing what your machine is worth on the market is the starting point for understanding both sides.
When Selling Can Trigger It (and Why Fully Depreciated Machines Surprise People)
Selling can trigger depreciation recapture whenever the sale price is above the adjusted basis, and the surprise is biggest on a machine written down to near zero on the books, because almost the entire sale price can then be a recaptured gain.
The biggest surprise hits sellers with fully depreciated machines. A machine that has been written down to nearly zero on the books still sells for real money on the used market. When the basis is near zero and the sale price is real, almost the entire sale price is a gain over that basis. A large share of that gain can be recaptured and taxed as ordinary income, and the seller never saw it coming because the machine "was worth nothing on the books."
That is the trap. The book value said zero, the market said otherwise, and the tax follows the market price, not the book number. It catches shop owners who assumed a written-off machine had no tax consequence at all.
Here is the honest framing, and it matters. This is not a reason to keep a machine you do not use, and it is not a reason not to sell. A machine sitting idle is still costing you floor space and tying up value. The point is to know your real sale number and loop in your CPA before you sell, not after, so there are no surprises at tax time. The reason a written-off machine still commands a real price is the same reason it is worth selling rather than scrapping, and how a CNC machine loses and holds value over time lays out why book value and market value drift so far apart.
How to Think About It Before You Sell
Before you sell, the general way to think about depreciation recapture is to gather four things for your CPA, your original cost, the depreciation you have taken, a realistic current sale price, and your timing, and let them run the actual numbers.
This is general guidance, not advice, so treat it as a way to prepare for the conversation, not a substitute for it. Your CPA runs the real numbers. What you can do is walk in with the right inputs ready. There are four:
- What you originally paid. The purchase price of the machine when you bought it.
- The depreciation you have taken. Your accountant has this, including any Section 179 or bonus first-year expensing that let you deduct a large chunk up front. That first-year expensing is part of why a machine can show a very low basis quickly.
- A realistic market sale price for the machine today. This is the one input you do not have yet, and the one MTE supplies for free.
- The timing. Whether you sell this tax year or next, and whether you are selling outright or trading toward a replacement, can change the picture. That is a question for your CPA, not a do-it-yourself calculation.
Notice that three of the four already live in your records or your accountant's files. The missing piece, almost every time, is a realistic current sale price, because book value is not market price and a guess is not good enough to plan around. That is the gap MTE fills. Two of the adjacent tax questions, how a Section 179 deduction specifically gets recaptured and how the part of a gain above your original cost is treated as a capital gain rather than recapture, are their own topics your CPA can walk you through. For the documentation side of an actual sale, here is the paperwork a sale needs.
The First Step Before the Tax Conversation: Get a Real Number
Before you can estimate any tax on a machine sale, you need the sale price, and MTE gives that number for free: MTE buys used CNC machines directly nationwide across all 50 states, gives a fair market-based quote, typically within 24 to 48 hours, which is typical market context and not a guarantee, handles the rigging and freight, and pays at pickup.
Having walked through the concept honestly, here is the one piece MTE is actually the authority on: the market number, not the tax. MTE is the buyer, not a tax advisor. The number we give you is yours to take to your CPA. We are not a broker, not a marketplace, not an auction, not a consignment shop, and not a tax firm. No commissions, no listing fees.
Getting that number is three steps.
Step 1: Tell Us What You Have
Call 800-822-9524 or tell us what you have through the online form. Give us the make and model, serial number, year, hours if known, control type, and condition. Photos of the control, the table or spindle, and the data tag speed up the quote. We buy nationwide, single machines or a full shop, running or not.
Step 2: Get a Market-Based Number
MTE values the machine against current secondary-market data and the specs you send. The offer is transparent, with no lowball formulas and no obligation. It typically comes back within 24 to 48 hours, which is typical market context, not a guaranteed turnaround.
Step 3: Take That Number to Your CPA, or Accept the Offer
The market number is the input your accountant needs to run the tax side, including any depreciation recapture. Take it to them, or, if you accept, MTE arranges and pays the rigging and freight nationwide, works around your schedule, and pays at pickup. No listing, no auction wait, no commission.

Frequently Asked Questions
What is depreciation recapture when you sell equipment?
Depreciation recapture is a tax rule that applies when you sell business equipment, like a CNC machine, for more than its depreciated tax basis. Over the years you owned it, you likely deducted depreciation, which lowered your taxable income. When you sell above what is left on the books, the IRS can "recapture" that benefit by taxing part of the gain as ordinary income instead of at the lower capital-gains rate. This is general information, not tax advice, so confirm the specifics with your CPA. MTE can give you the market sale number you will need at 800-822-9524.
Is depreciation recapture the same as a machine losing value over time?
No, and this is the part people mix up. A machine losing value over time is an economic thing, how much it is worth on the used market as it ages. Depreciation recapture is a tax thing, the treatment of the depreciation deduction you already took, triggered when you sell above your adjusted basis. They share the word depreciation and nothing else. A machine can be worth far more on the used market than its book value, and that gap is exactly what can create a recapture event when you sell.
Do I owe tax if I sell a fully depreciated CNC machine?
Possibly, and it surprises a lot of sellers. A machine written down to nearly zero on your books can still sell for real money on the used market, and that sale can be a gain over the near-zero basis, so a large share of it can be recaptured and taxed as ordinary income. That is a reason to know your real sale number and talk to your CPA before you sell, not a reason to keep a machine you do not use. This is general information, not tax advice.
How do I figure out the recapture on a machine I am selling?
Your CPA or tax professional figures the actual number, because it depends on your original cost, the depreciation you took including any Section 179 or bonus expensing, your sale price, and your tax situation. What you can gather before that conversation is the one input they do not have: a realistic market sale price for the machine today. MTE gives you that number for free, fast, with no obligation, so you and your accountant can run the tax side accurately.
Does MTE handle the tax side when I sell?
No. MTE is the buyer, not a tax advisor. We give you a fair, market-based number for your machine, typically within 24 to 48 hours, and we handle the rigging, freight, and payment at pickup. The tax side, including any depreciation recapture, is for you and your CPA, and our number is the first input they need. This page is general information, not tax advice.
