HVAC Asset Sale vs. Stock Sale: Taxes (2026)

Nearly every HVAC sale is an asset sale, where the buyer takes your trucks, customers, and name but not your company. You would do better selling the company. Buyers almost always win this.

• On a $5M deal, the structure moves $130K to $700K between you and the buyer, depending on your state.
• Your written-off trucks are the reason. They get taxed at your regular rate on the way out.
• Decide before you sign the offer. After that, the structure is set and you are arguing about scraps.

What You Are Actually Selling

In an asset sale the buyer picks up the pieces of your business and leaves the company behind.

• The physical stuff: trucks, tools, equipment, and parts inventory.
• The valuable stuff: your customer list, service agreements, phone number, website, and name.
• Your crew, who get offered jobs by the new owner rather than transferring automatically.
• Not your company. The corporation or LLC stays with you, along with everything in its past.

In a stock sale, you sell the company itself. Everything inside it comes along, good and bad, and only the ownership changes.

Why Buyers Insist on Asset Sales

Two reasons, and both are worth a lot of money to them.

• They get to write off what they paid you. The price becomes their new cost basis, which they deduct over the following years.
• They leave your history behind. An old lawsuit, an unpaid tax bill, a refrigerant violation: all of it stays with your company, not theirs.
• They can pick and choose. Tired trucks, bad contracts, a customer who never pays. They just decline those.

Why It Costs You

The price gets split across what you sold, and each piece is taxed differently.

• Your customer base and name get the long-term rate of 15% or 20%, plus a 3.8% investment income tax if you earn enough.
• Your trucks and equipment are different. Anything you already deducted gets taxed again at your regular rate, up to 37%.
• That hits HVAC harder than most trades. A fleet of written-off vans is a big number in the wrong column.
• If you are a C corporation, it is worse. The company pays tax on the sale, then you pay again when you take the money out.

You and the buyer also fight over the split. They want more against equipment, which they write off fast. You want more against your customer base, which is taxed lower.

The Math on a $5M Sale

Take a $5M sale where you originally put in $500K, you run an S corporation, and you are in the 20% federal bracket.

Selling the Company, No State Tax

• Your gain is $4.5M, all of it at the lower rate.
• Federal tax: $900K. Investment income tax: $171K.
• You keep about $3.93M.

Selling the Assets, No State Tax

• Say $1M lands against equipment and $4M against your customer base.
• The equipment piece is taxed like wages: $370K.
• The rest gets the lower rate: $700K, plus $133K of investment income tax.
• You keep about $3.8M.

That is $130K, on a deal with no state tax at all. Add a high-tax state and the gap widens toward $700K.

Side by Side

When You Can Actually Sell the Company

It happens, just not often. These are the situations where a buyer agrees.

• Contracts that will not move. Commercial maintenance agreements, municipal work, or manufacturer authorizations that would have to be renegotiated one by one.
• Licensing that is a nuisance to rebuild, especially commercial mechanical work in cities with their own rules.
• Big deals. Platforms buying above $10M sometimes have the legal machinery to take the company whole. Smaller roll-ups almost never do.

The Middle Ground for S Corporations

There is an election that lets a company sale be treated like an asset sale for tax purposes. Your accountant will call it a 338(h)(10).

The buyer gets the write-off they wanted. You get a shot at a higher price for handing it to them.

• You have to be an S corporation, and your buyer has to be a corporation taking at least 80%.
• Both sides elect it together, on IRS Form 8023, with a filing deadline after closing.
• You take more tax now, but the price bump often more than covers it. Model it before you agree.

Where You Live Changes the Answer

The federal math is the same everywhere. The state math is not, and it is often the bigger number.

• No state income tax at all: Florida, Texas, Tennessee, Nevada, Washington, Wyoming, and South Dakota.
• Gentle: Pennsylvania takes a flat 3.07%, one of the lowest anywhere.
• Harsh: New Jersey taxes the gain like income, up to 10.75%. California and New York are in the same territory.
• Watch the states you work in, not just where you live. An asset sale can owe tax in every state where you have real operations.

Settle This Before You Sign

The offer usually names the structure. Once you sign it, you are negotiating from behind.

1. Have your accountant run both structures against your actual entity type.
2. Estimate how much of the price will land against equipment you already wrote off.
3. List every state where you do enough work to owe tax there.
4. If you are an S corporation selling to a corporate buyer, price out the election above.

The question is never really asset or company. It is what you keep under each one, and how hard you can push.
