You expensed a machine under Section 179 a few years back, or maybe you took bonus depreciation, and now you are thinking about selling it. Then someone mentioned you might owe tax on the sale, and that did not sound right, because you already wrote the thing off. Here is the plain reality, said calmly: that machine probably has a low or even zero tax basis now, so selling it can create a taxable gain, often taxed as ordinary income. This is one of the most common surprises in an equipment sale, and it does not mean Section 179 was the wrong call.
Before we go further, the guardrail, said straight: this is general information, not tax advice, and your CPA runs your actual number. This guide explains the concept in plain English so you are not blindsided, names the words your CPA will use, and points you to current IRS guidance for the rules that change year to year. Jason Puuri runs acquisition at MTE and has bought equipment from many owners who were surprised by the tax side of a sale, so the picture below is the one we walk sellers through all the time.
When you decide to sell, the clean route also makes the tax side easier, because a direct sale gives your CPA one clear price to work from. Call 800-822-9524 or get a free quote.
What Section 179 Did to Your Tax Basis
When you expensed a machine under Section 179, you deducted its cost up front, which lowered its tax basis, often all the way to zero.
Tax basis is a plain idea wearing an accounting word. It is roughly what the equipment is "worth" to the IRS on your books after you have taken your deductions. You start with what you paid, and every deduction you take against that machine pulls the number down. Expensing the whole cost in one year, or depreciating the machine fully over time, drives that basis toward zero by design. That is the point of the deduction.
So a zero-basis machine is normal for an asset you expensed. It is not a red flag, and it does not mean the books are wrong. It means you already took the tax benefit of owning it.
Section 179 and bonus depreciation are simply the two up-front-expensing mechanisms. Instead of spreading a machine's cost across many years, they let a business deduct a large share, sometimes all of it, in the year of purchase. The exact limits and percentages change with the law, so this guide does not state them. For the related question of how a machine's book value falls while its real market value holds, see how depreciation and book value work, which covers that curve in full. This is general information, not tax advice, and your CPA or your depreciation schedule has your actual basis.
What Depreciation Recapture Is
Depreciation recapture is the rule that when you sell equipment for more than its now low or zero tax basis, the part of the gain that came from your earlier deductions gets recaptured and taxed.
Think of it as a two-part deal. Part one happened years ago: you bought the machine and deducted its cost, which lowered your taxable income then. Part two happens when you sell: the IRS effectively reclaims the tax benefit on the portion of the sale price that exceeds your remaining basis. That reclaimed portion is the recapture.
In practical terms, the recaptured amount is generally reported on Form 4797 and generally taxed as ordinary income rather than at capital-gains rates. This guide names the form and the treatment but states no rate, because rates and rules change, and the right source for the current number is your CPA and current IRS guidance.
Here is the honest reassurance, because the worry is the part that keeps people from selling: recapture is one of the most common surprises in an equipment sale, and it does not mean Section 179 was a mistake. You got real value from the deduction when you took it. The sale just settles the back end of that same deal. Your CPA computes what is owed; current IRS guidance sets the rules.
Why a Used Machine Sale Can Still Be Taxable
A fully expensed machine can produce a taxable gain on sale because the gain is measured against your tax basis, not against what you originally paid, so even a used machine sold for less than its purchase price can create taxable income.
This is the part that catches owners off guard, and it is worth slowing down on. The natural reaction is, "I am selling it for less than I paid, so how can there be a gain?" The answer is that purchase price is not the yardstick. Basis is.
If you paid a sum for the machine and then expensed it under Section 179 or depreciated it fully, your basis may be at or near zero. The taxable gain is roughly the sale price minus that remaining basis. So a machine you sell for well under what you paid can still produce a gain, because the comparison is sale price against basis, and basis is the low or zero number your deductions created. Selling below your purchase price does not, on its own, mean there is no gain to report.
That makes the sale price one of the two numbers in the math, which is exactly why knowing what the machine is worth matters before you sell. If you want a real sense of that figure, here is what your machine is worth today, driven by the model, age, hours, control generation, condition, and current demand. This is general information, not tax advice. Your CPA takes your basis and your sale price and computes the actual number.
What This Means When You Decide to Sell
If you are planning to sell equipment you expensed, the practical move is to expect a possible tax effect, get a real sense of the sale price, keep clean records, and talk to your CPA before you close, not after.
None of this should stop a sale that makes sense. It just means you go in with eyes open. Here is what to line up before you sell. Read this as a list of things to have ready, not as tax strategy.
- Know your approximate basis. Your CPA or your depreciation schedule has it, and it is the starting point for the whole calculation.
- Get a real market value for the machine. That is the sale-price side of the math, and a fair, current number beats a guess.
- Keep the bill of sale and the sale documentation. A clean paper trail is what makes the tax side simple later, and the paperwork a clean sale produces walks through exactly what that looks like.
- Time the sale with your tax year in mind. Whether to close in one year or the next is your CPA's call, not a rule of thumb.
- Ask your CPA to estimate the effect before you commit. A quick conversation up front prevents an ugly surprise at filing time.
The single most useful habit here is to bring your CPA in early, before you close, while there is still room to plan the timing. That is general information, not tax advice, but it is the move that turns a surprise into a known number.
General Information, Not Tax Advice
This page is general information about how Section 179 and depreciation recapture commonly work, not tax or legal advice, and your specific situation depends on facts only your CPA and current IRS rules can settle.
Let us draw the boundary clearly, because it matters. The rules, the limits, and the rates change year to year. The dollar figures are deliberately not stated on this page, because the moment a page prints this year's Section 179 limit or bonus-depreciation percentage, it starts going stale. Your actual outcome depends on your basis, your sale price, your business entity, and your overall tax picture, and no general article can know those.
So the right move is to take the concept here to the people whose job it is. Your CPA runs your number. Current IRS guidance sets the rules, including Form 4797 for reporting the sale and the IRS depreciation publications for the mechanics. MTE is an equipment buyer, not a tax advisor and not a CPA firm. We can tell you what a machine is worth and give you clean sale documentation. We cannot, and do not, tell you what you owe. That line is the honest one, and keeping to it is part of how this stays useful instead of becoming a stale figure dump.
When You Decide to Sell: the Clean-Transaction Route
If you want a clean transaction your CPA can work from, MTE buys used CNC machines directly nationwide, gives one clear sale price with a real bill of sale, handles the rigging and freight, and pays at pickup.
Having walked through the concept honestly, here is the practical wedge. When you decide to sell, a direct outright sale gives your CPA the cleanest possible input: one clear sale price and a real bill of sale, with no commissions, listing fees, or auction premiums to net out. Marketplaces, brokers, auctions, and consignment all muddy that number with deductions and timing, which means more for the CPA to untangle. A direct sale to MTE is one price, documented once.
Machine Tool Exchange buys used CNC machines directly in all 50 states. We pay at pickup and we handle the rigging and freight, so the transaction is simple to document and simple to close. We are not a broker, not a marketplace, not an auction, and not a consignment shop, and we are not a tax advisor, so your CPA still runs the actual number. What we do is make the sale itself clean.
Step 1: Tell Us What You Have
Give us the make and model, serial, year, hours if known, control type, and condition. Photos of the control, the table or spindle, and the data tag speed up the quote. Call 800-822-9524 or tell us what you have through the online form in a few minutes. We buy nationwide, a single machine or a full shop, running or not.
Step 2: Get a Market-Based Quote
MTE values the machine against current secondary-market data and the specs you send. The offer is transparent, with no obligation, and it typically comes back within 24 to 48 hours. That timeline is typical market context, not a guarantee or a fixed quote, and the number is a market-based offer, not a formula.
Step 3: We Rig It, Haul It, and Pay at Pickup
Accept the quote and MTE arranges and pays for the rigging and freight nationwide, works around your schedule, and pays at pickup. You get clean sale documentation, a real bill of sale and one clear price, which is exactly what your CPA needs to compute the gain. Jason Puuri runs acquisition at MTE and decides the number and writes the check directly, so you are dealing with the buyer and you get clean paperwork, not a third-party sale to untangle at tax time.

Frequently Asked Questions
Do I have to pay tax if I sell a machine I expensed under Section 179?
Possibly, yes. When you expensed the machine under Section 179, you lowered its tax basis, often to zero. When you sell it for more than that basis, the part of the gain that came from your earlier deduction can be recaptured and taxed, generally as ordinary income. This is one of the most common surprises in an equipment sale, and it does not mean Section 179 was the wrong choice. The actual number depends on your basis, your sale price, and your tax situation, so talk to your CPA. This is general information, not tax advice.
Why would I owe tax on a used machine I sold for less than I paid?
Because the taxable gain is measured against your tax basis, not against what you originally paid. If you expensed the machine under Section 179 or fully depreciated it, your basis may be zero, so almost the entire sale price can be a taxable gain even though you sold it for less than the purchase price. Selling below what you paid does not mean there is no gain. Your CPA computes the exact figure from your basis and the sale price.
What is depreciation recapture in plain terms?
Depreciation recapture is the rule that when you sell equipment you previously deducted, the IRS reclaims the tax benefit of those earlier deductions on the gain. You got the deduction up front through Section 179, bonus depreciation, or regular depreciation, so when you sell for more than your remaining basis, that recaptured portion is generally taxed as ordinary income and reported on Form 4797. The current rules and rates change, so check current IRS guidance and your CPA for your specific situation.
Does a clean sale make the tax side easier?
It helps. A direct outright sale gives you one clear sale price and a real bill of sale, with no commissions, listing fees, or auction premiums to net out, which is the cleanest input your CPA needs to compute the gain. MTE buys direct, provides clear sale documentation, handles the rigging and freight, and pays at pickup, so the transaction is simple to document. We are an equipment buyer, not a tax advisor, so your CPA still runs the actual number, but a clean transaction makes their job easier.
Should I figure out the tax before or after I sell the machine?
Before. Talk to your CPA before you close the sale, not after, so there are no surprises at tax time and so you can plan the timing with your tax year in mind. To make that conversation useful, have an approximate basis (your CPA or depreciation schedule has it) and a real market value for the machine. MTE can give you a fair market-based number on the machine so your CPA has the sale-price side to work from. Call 800-822-9524 when you are ready for that number.
Know the Tax Picture, Then Get a Number
You do not have to be an accountant to sell a machine you expensed.
