You are about to sell a used CNC machine and you want to know the tax angle before you call your accountant. Here is the plain version. Selling business equipment can be a taxable event, which means the sale may have income-tax consequences, and how much tax you owe, if any, depends on what you originally paid for the machine, how much depreciation you already took, and what you sell it for.
This guide explains those concepts in plain English so the conversation with your accountant goes faster and smarter. One thing to be clear about up front: this is general information, not tax or legal advice, and the specifics for your situation come from your own CPA or tax advisor. Jason Puuri runs acquisition at MTE, where he values and buys used CNC machines direct, and the one number a CPA needs from a sale, the sale price, is exactly what MTE provides. If you want the bigger picture on the sale itself, here is how to sell a used CNC machine start to finish.
The honest split is simple. For the tax answer, your CPA. For the market-based sale-price number your CPA will need, MTE. Call 800-822-9524 or get a free market-based quote.
Selling Equipment Can Be a Taxable Event
Selling a business asset like a used CNC machine can be a taxable event, which means the sale may have income-tax consequences, separate from any sales tax on the transaction.
The tax code generally treats business equipment differently from personal property. When you sell a machine that you used in your business, the gain or loss on that sale can affect your income taxes for the year. That is what "taxable event" means here. It does not automatically mean you owe a large bill, and it does not mean the sale is taxed the same way for every seller. It means the sale is something the tax code looks at, and the result depends on your numbers.
There are really two separate tax topics around a machine sale, and it helps to keep them apart. The first is the income-tax consequence to you, the seller, which is what this page is about. The second is sales tax, which may apply to the transaction itself depending on your state and how the sale is structured. Those are different questions handled in different places. The document side of the sale, including the bill of sale and the sales-tax question, lives with the paperwork a sale needs.
For the income-tax side, the amount and the treatment depend entirely on your specific situation: your records, your prior depreciation, and the sale price. Your CPA computes the actual number. The job of this page is to name the parts so that conversation is short.
Depreciation Recapture: Why Your Prior Write-Offs Matter
Depreciation recapture is the idea that if you wrote off the cost of a machine over time, including through Section 179 or bonus depreciation, some of the proceeds when you sell can be taxed back, often as ordinary income rather than at capital-gain treatment.
This is the concept that surprises sellers most, so it is worth slowing down on. While you owned the machine, you very likely deducted its cost against your taxable income. You may have done that gradually over several years, or all at once in the year you bought it through Section 179 or bonus depreciation, which are the common ways shops write off CNC equipment. Either way, those deductions lowered your taxable income at the time.
Depreciation recapture is the tax code's way of looking back at that. When you sell the machine, part of the money you receive can be treated as recovering the benefit you already took, and that recaptured portion is often taxed as ordinary income rather than getting capital-gain treatment. In plain terms, you got a tax break while you owned it, and some of that break can come back into the picture when you sell.
Whether recapture applies to you, and how much, depends on your records and your situation. There is no single rule that fits every seller, which is exactly why your CPA is the one to work it out. This is general information, not tax advice. One related point that trips people up: a machine you have fully written off on your books still has real market value, which is a separate question from the tax question. If you are tracking how value moves over time, here is how CNC machines lose value over time, and the short version is that book value and market value are not the same number.
Capital Gain vs Ordinary Income
When you sell a CNC machine, the profit can be treated as ordinary income or as a capital gain depending on the machine, how long you held it, and how much depreciation you took, and the two are generally taxed differently.
These two labels matter because they are generally taxed in different ways. Ordinary income is the same bucket your regular business income falls into. A capital gain is the gain on the sale of a capital asset, and it can be treated differently. On the sale of a used CNC machine, the profit is not always one or the other. It can be a mix, with part treated as recaptured ordinary income, as described above, and part potentially treated as a capital gain.
How the profit splits between the two comes down to the details: the kind of property the machine is, how long you owned it, and how much depreciation you claimed along the way. That split is exactly the kind of calculation a CPA does, using your basis and your depreciation history. The point here is to understand that the question exists and that the answer is not a flat one-size figure.
So when someone asks whether the money from selling a machine is taxed as a gain or as income, the honest answer is "it depends, and often it is both." That is not a dodge. It is the real mechanism. Your CPA or tax advisor sorts the split for your situation. This page is general information, not tax advice.
Your Basis and Prior Depreciation Drive the Number
Your tax basis is generally what you originally paid for the machine, reduced by the depreciation you have already taken, and that adjusted basis compared to your sale price is what determines the gain or loss.
Basis is the anchor concept that ties the others together, and it is simpler than it sounds. Your basis usually starts as what you originally paid for the machine. As you take depreciation over the years, that basis goes down. What is left is your adjusted basis. When you sell, the tax outcome turns on the relationship between that adjusted basis and your sale price. Sell for more than your adjusted basis and there is generally a gain. Sell for less and there can be a loss.
The reassuring part is that you do not have to compute any of this yourself. You need to provide the inputs, not the math. There are three inputs that matter: what you originally paid, the depreciation you have already taken, and a real sale price. The first two come from your own books and your accountant. The third is the sale-price number, and that is the one piece an outside buyer can hand you quickly. If you are still researching what the machine is worth on the market, here is what your machine is worth, and a deeper look at what drives resale value.
That is the whole arc. Original cost, minus prior depreciation, gives adjusted basis. Adjusted basis against the sale price drives the gain or loss. Recapture and the gain-versus-income split sit on top. Your CPA runs it. You gather the inputs. This is general information, not tax advice.
Records: What Your CPA Will Want
To figure the tax on a CNC machine sale, your accountant generally needs your original purchase records, the depreciation you have already claimed, and the final sale price or bill of sale.
Good records turn a tax question that feels scary into a short conversation. Here is a generally useful list of what to pull together before you call your accountant:
- The original invoice or purchase records, showing what you paid for the machine.
- The depreciation schedule, from your own books or from your accountant, showing what you have already claimed.
- The bill of sale or the agreed sale price for the machine.
- Any records of major improvements or significant repairs, since those can affect the picture.
Having those in hand makes the CPA's job, and yours, faster and harder to get wrong. This is general guidance, not advice, and your CPA confirms what applies to you. One more note on records: in some situations a formal valuation matters more than usual. An estate being divided among heirs, or a value needed for tax purposes, can call for a formal appraisal rather than a quick market number. If your situation is one of those, you can get a formal appraisal. For a straightforward sale, the purchase records, the depreciation schedule, and a real sale price are usually what the conversation needs. The document side of the transaction itself is covered in the paperwork a sale needs. For the sale-price input, MTE can hand you a fair market-based number, with no obligation, at 800-822-9524.

Frequently Asked Questions
Do I have to pay tax when I sell a used CNC machine?
Possibly. Selling business equipment can be a taxable event, which means the sale may have income-tax consequences separate from any sales tax. Whether you owe tax, and how much, depends on what you originally paid, how much depreciation you have already taken, and what you sell it for. This is general information, not tax advice, so your own CPA or tax advisor is the right person to tell you what applies to your situation. MTE can give you a fair market-based number for the sale price your accountant will need, at 800-822-9524.
What is depreciation recapture on equipment?
Depreciation recapture is the idea that if you wrote off the cost of a machine over time, including through Section 179 or bonus depreciation, some of the money you get when you sell it can be taxed back, often as ordinary income rather than at capital-gain treatment. In plain terms, you lowered your taxable income while you owned the machine, and the tax code can recapture part of that benefit when you sell. Whether it applies to you and how much depends on your records, so confirm the specifics with your CPA. This is general information, not tax advice.
Is the money from selling a CNC machine capital gain or ordinary income?
It can be either, and often a mix, depending on the machine, how long you held it, and how much depreciation you took. Ordinary income and capital gains are generally taxed differently, and the split on an equipment sale is exactly the kind of thing your accountant sorts out using your basis and your depreciation history. This page is general information, not tax advice, so talk to your CPA or tax advisor for how it works in your case.
Do I owe tax if my CNC machine is fully depreciated?
Often there can still be a tax consequence. A machine that is fully written off on your books usually has a low or zero tax basis, so selling it can produce a gain, and depreciation recapture can apply even when the machine is fully depreciated. A fully depreciated machine almost always still has real market value too, which is a separate point. For what you would actually owe, consult your CPA or tax advisor. This is general information, not tax advice.
What records do I need to figure the tax on selling my machine?
Generally your accountant will want your original purchase records or what you paid, the depreciation you have already claimed, and the final sale price or bill of sale. Good records make the tax simpler to figure and harder to get wrong. The document side of the sale itself, like the bill of sale and proof of ownership, is covered separately. This is general guidance, not tax or legal advice, so your CPA or tax advisor should confirm what you need.
