How Does Capital Gains Tax Work When Selling a Business?
Selling your business should be a win-win for you, but many owners face a rude awakening when taxes claim 30-50% of their proceeds. In 2025, while long-term capital gains rates range from 0-20%, the real cost is often higher.
A $5 million sale could trigger a 20% federal government tax, plus 13.3% in states like California, with depreciation recapture adding another 5-25% on equipment and property. This means your exit strategy determines whether you keep the maximum from your life’s work.
In this article, we break down how capital gains tax works and how it affects your business valuation. We also discuss when it becomes due and strategies for minimizing capital gains tax in a business sale.
Key Takeaways
- Without proper tax planning, 40-60% of your business sale proceeds can be lost to capital gains, depreciation recapture, and state taxes.
- The sale structure impacts your tax burden. Asset sales cost sellers more in taxes, while stock sales favor sellers through lower capital gains rates.
- NEO Business Advisors collaborates with your financial team to optimize deal structures and maximize your after-tax proceeds from the sale.
What Is Capital Gains Tax?
Capital gains are the money you make when you sell an asset (it’s the opposite of capital losses). Capital gains tax is the duty you pay when you sell assets for more than you paid for them. Examples include your business, stocks, personal property, rental property, and valuable collectibles like precious metals.
The tax rate on capital gains also depends on how long you’ve held the asset:
- Short-term gains. If you sell an asset you’ve owned for one year or less, the profit is considered a short-term capital gain. These gains are taxed at your ordinary income tax rate, which can range from 10% to 37% depending on your total taxable income.
- Long-term capital gains. If you sell an asset after holding it for more than one year, the profit is a long-term capital gain. These gains benefit from lower tax rates like 0%, 15%, or 20%, usually based on your taxable income and filing status.
To put this into perspective, let’s say you started a business with an investment of $100,000, then sold it for $300,000 down the line. Your capital gain is $200,000. If you have owned the business for more than one year, the $200,000 will be taxed at the applicable long-term rate based on your income.
But if you owned your business for one year or less, your capital gain will be taxed at your ordinary income tax rate. There are many online tax calculators that can help you figure out your taxes for a calendar year.
When Does Capital Gains Tax Apply in a Business Sale?
Capital gains tax liability kicks in when you sell your business or its assets for more than you paid. But how it applies depends on the sale structure:
- Asset sale. In this sale, the buyer purchases individual pieces (equipment, inventory, goodwill, etc.). Taxes vary by asset type. Profits on long-held assets (like real estate or intellectual property) qualify for lower capital gains rates, while inventory or recently depreciated equipment may be taxed as ordinary income.
- Stock sale. In a stock sale, the buyer acquires ownership shares (common for corporations). If you’ve held the stock for over a year, profits typically qualify for long-term capital gains rates (0%, 15%, or 20%).
Tax rates also depend on federal and state rules for a given year. For the 2025 tax year, federal long-term capital gains rates max out at 20% for high earners. Here’s what you can expect to pay according to the different rates:
| Tax filing status | 0% rate amount | 15% rate amount | 20% rate amount |
|---|---|---|---|
| Single | $0 to $48,350 | $48,351 to $533,400 | $533,401 and above |
| Head of household | $0 to $64,750 | $64,751 to $566,700 | $566,701 and above |
| Married couple filing jointly | $0 to $96,700 | $96,701 to $600,050 | $600,051 and above |
| Married but filing separately | $0 to $48,350 | $48,351 to $300,000 | $300,001 and above |
Some states also add their own taxes. For example, Ohio taxes capital gains as ordinary income but at relatively low rates ranging from 0% to 3.5%, depending on your income level.
Here’s an example of how this plays out.
If you sell your manufacturing business for $10 million after a $100,000 investment, your capital gain is $9.9 million.
In Ohio, you would pay an additional 3.5% on income over $100,000, amounting to approximately $344,650 in state taxes (the first $26,050 is taxed at 0%, the next $73,950 at 2.75%, and the remaining $9.8 million at 3.5%). This is in addition to the federal capital gains tax.
Why It Matters: The Financial Impact of Capital Gains Tax
Selling a business for a million (or more) might feel like a windfall until taxes take their cut. The reality is that your actual proceeds could be 25-40% less than the sale price, depending on how the deal is structured and where you live.
Let’s say you’ve owned a clothing brand for five years (without any partners) and want to sell. You have two options:
1. Stock Sale
You want to sell all of your business’s stock for $1 million. Since you have owned your business for over a year, it qualifies for long-term capital gains rates. This means you’ll have to pay:
- 20% federal income tax
- 5% average state capital gains tax
Your total taxes will be $250,000, and you keep $750,000.
2. Asset Sale
Different tax rates apply for most assets. Here are a few examples:
- Equipment/inventory will be taxed as ordinary income (up to 37%)
- Real property may be taxed at 25%, especially if you claimed depreciation deductions on buildings/equipment
- Goodwill will get capital gains rates (15-20%)
This means in asset sales, you’re forced to categorize every dollar of the sale price. This is good for the buyer since they get a step up in basis for assets you have fully depreciated or taken accelerated depreciation on that still have useful life and value in the sale.
However, for the seller, more of the sale price gets pushed into higher-tax categories. The result is a less predictable actual take-home.
Asset Sale vs. Stock Sale: Tax Implications Explained
As we’ve explained, the structure of your sale (asset or stock) will affect how much capital gains taxes you will pay. Here’s a quick breakdown:
| Parameter | Asset sale | Stock sale |
|---|---|---|
| What’s sold | Individual assets (equipment, inventory, real estate, goodwill, etc.) | Company ownership shares (stock or LLC membership interests) |
| Tax treatment | Mixed:Inventory is classified as ordinary income (up to 37%)Equipment can get potential depreciation recapture (up to 25%)Goodwill/intangibles incur capital gains tax (0%/ 15%/ 20%) | Entire gain taxed as capital gains (short-term capital gains tax rate if held less than one year; long-term if held for more than one year) |
| Seller’s tax burden | Typically higher (due to ordinary income on some assets) | Typically lower (long-term capital gains rates apply) |
| Buyer’s tax benefit | Step-up in basis (higher depreciation/amortization deductions post-sale) | No step-up (inherits seller’s existing tax basis, which limits future deductions) |
| Complexity | High (requires asset-by-asset allocation and separate tax treatments) | Low (single capital gain calculation) |
Let’s go into more detail below:
When You Sell Assets
In the sale of a capital asset, you sell the individual pieces of your business separately. This creates a tax challenge because different types of assets are taxed differently:
- Things you sell from inventory get taxed at your regular income tax rate (up to 37%)
- Your business reputation and customer relationships (goodwill) get the lower capital gains rate (0-20%)
- For equipment you’ve written off over the years, the Internal Revenue Service wants some of those deductions back through “depreciation recapture,” taxed up to 25%
As a result, your money gets split into different tax buckets, leaving you with a higher overall tax bill.
Buyers love asset deals because they can restart the depreciation clock on everything they buy, giving them fresh tax deductions for years to come.
When You Sell Stock
When you sell your business as stock (your ownership papers), the entire profit qualifies for the lower long-term capital gains tax rate (0-20%) if you’ve owned it for over a year. This single tax rate is usually much more favorable than the mixed rates in an asset sale.
However, buyers generally dislike stock purchases because they inherit your original tax values for all assets. This means fewer tax deductions for them going forward, so they might offer less money for a stock deal.
Strategies for Minimizing Capital Gains Tax in a Business Sale
While every business sale is unique, these general strategies can help reduce your tax burden.
The following information is provided for general guidance on managing capital gains tax and should not be considered legal or tax advice. Consult with financial professionals for in-depth legal advice for your specific situation.
1. Plan Ahead and Start Tax Planning Early
Tax laws are complex, and many strategies require time to implement. This means last-minute planning can often leave money on the table. For example, converting from a C-corporation to an S-corporation or LLC has to be done well in advance to avoid IRS scrutiny and to meet the necessary holding periods.
This means the key is to get your exit strategy tax planning started 1-3 years ahead, when you still have options to optimize your tax position before buyers come to the table.
Early planning also helps you time the sale to qualify for long-term capital gains rates (0-20%) instead of higher ordinary income rates (up to 37%).
You also have enough time to clean up your financial records, maximize available deductions, and potentially restructure the business to be more tax-efficient.
2. Consider an Installment Sale
Instead of receiving all your money at once (and owing all taxes immediately), an installment sale lets you receive payments over several years.
This is important because when you get all your money in one year, you could end up in a much higher income tax bracket. But when you spread payments out, you’ll likely pay taxes at lower rates each year.
For instance, a $3 million gain taxed all at once might push you into the highest bracket (37%), while spreading it over three years could keep you at 20-24%.
However, there are risks. If the buyer defaults, you could lose future payments, so you need to make sure proper legal protections like escrow accounts or collateral are in place.
3. Maximize Long-Term Gains
The difference between short-term (ordinary income) and long-term capital gains rates can mean hundreds of thousands in tax savings.
Any assets held for more than one year qualify for preferential rates (0%, 15%, or 20%, depending on your income). If you’re close to the one-year mark, it may be worth delaying the sale to get these lower rates and increase the value of your business before exiting.
And if you’re a C-corporation owner, the qualified small business stock (QSBS) exemption can help you exclude up to $10 million or more in gains if you’ve held the stock for over five years.
4. Allocate Purchase Price Strategically
In an asset sale, how the purchase price is allocated among different asset categories will massively impact your tax bill.
Buyers typically want more allocated to depreciable assets like equipment (which they can write off quickly), while sellers prefer allocations to goodwill (taxed at lower capital gains rates). This means you need to drive a hard bargain at the negotiation table.
A skilled tax advisor can help you structure the negotiation to minimize your liability while still making the deal attractive to buyers. In some cases, buyers may agree to a higher total purchase price if the allocation favors them.
5. Use Retirement Accounts or Reinvestment Strategies
Creative reinvestment strategies can defer or even do away with capital gains taxes. For example, qualified opportunity zone (QOZ) investments help you defer gains until 2026, and if held for ten years, all appreciation becomes tax-free. These zones are federally designated economically distressed communities that offer tax benefits to investors.
If you have a self-directed Roth IRA or 401(k), you can use QOZ funds to purchase business interests that can give you tax advantages, though the rules are very complex.
Another option is a 1031 exchange for certain business real estate holdings. This tax provision allows you to defer paying capital gains taxes when you sell business property by reinvesting the proceeds into a similar property. In other words, the government lets you postpone your tax bill as long as you keep your money invested in real estate.
Each of these strategies (and others like tax-loss harvesting) has specific requirements and timeframes, so you need to have advisors on board at all times.
6. Explore Trusts or Charitable Remainder Trusts (Advanced)
If your business has sales above $5 million per year and you are planning a high-value exit, you may benefit from charitable remainder trusts (CRTs). With a CRT, you transfer business assets into a trust, which then sells them tax-free. You receive annual payments for life (partially tax-free), with the remainder going to charity. Think of it as an investment strategy.
This means you can do away with capital gains taxes entirely while getting lifetime income. Other trust structures, like intentionally defective grantor trusts (IDGTs), may also be worth it if you have a high net worth. But these strategies work only for high-value exits, so you should focus on your business’s valuation.
Common Mistakes Business Owners Make
Here are four common mistakes that can cost you hundreds of thousands of dollars in unnecessary tax payments and lost opportunities:
- Waiting too long to plan. The most expensive mistake is delaying tax planning until the sale is imminent. Effective tax strategies often require 12-24 months to implement properly. Take financial control of your future years now.
- Assuming all proceeds are after-tax. Many sellers make the dangerous assumption that a five-million-dollar sale price means five million in their pocket. In reality, between federal capital gains, state taxes, and potential depreciation recapture, sellers might net as little as 60% of the sale price.
- Not consulting a qualified tax advisor or tax professional. Not every CPA or broker is the same. During your sale of assets, make sure your financial advisor understands your industry and any associated special rules. You want someone with specialized knowledge about tax-advantaged accounts, tax breaks or tax cuts, and price allocation strategies.
- Overlooking state-specific rules. State taxes can be just as punishing as federal ones, and the rules vary wildly. For instance, California taxes capital gains as ordinary income, while states like Texas and Florida impose no income tax at all.
