You spent years building this business. When a buyer finally makes an offer, a significant portion of that number goes somewhere you may not have fully planned for: the IRS.
Capital gains tax on selling a business is one of the most misunderstood parts of the exit process. Sellers focus on the asking price and forget that the structure of the deal, the holding period, and the allocation of the purchase price all determine how much they actually keep.
Here is an honest breakdown of how it works so you can walk into negotiations knowing what the numbers actually mean.
How Capital Gains Tax on a Business Sale Actually Works
Capital gains tax on selling a business is a tax on the profit from selling a capital asset. The IRS taxes the difference between what you receive at closing and your adjusted basis in the business.
Your adjusted basis is roughly what you originally paid plus improvements, minus depreciation you have already claimed. If you built the business from scratch, your basis is likely very low. That means a large portion of the sale proceeds will be taxable.
The rate depends on how long you have owned the business:
- Short-term capital gains apply if you owned the business for one year or less. These are taxed at your ordinary income rate, which can reach 37% depending on your bracket.
- Long-term capital gains apply if you held the business for more than one year. Federal rates are 0%, 15%, or 20% depending on your income. Most sellers landing a deal in the $1M to $5M range will pay 20% at the federal level.
On top of the federal rate, most sellers also owe a 3.8% Net Investment Income Tax if their income exceeds $200K (single) or $250K (married filing jointly). That pushes the effective federal rate for many business sellers to 23.8%.
State capital gains taxes vary widely. California taxes capital gains as ordinary income, which means sellers there can face a combined effective rate north of 40%. Other states have no capital gains tax at all. Work with your CPA on the state-level calculation before you set your price expectations.
The Deal Structure Changes Everything
This is where most sellers get surprised.
In an asset sale, which is how most small business acquisitions close under $5M, different pieces of the deal are taxed differently. Not all of the purchase price is a capital gain.
When a buyer acquires your business assets, the purchase price gets allocated across categories: equipment, inventory, furniture, customer lists, non-compete agreements, and goodwill. The IRS has specific rules for this allocation under Section 1060, and both parties have to report it consistently.
Here is why that matters:
- Goodwill is typically taxed at long-term capital gains rates. Good for you.
- Equipment and other depreciable assets may trigger depreciation recapture, taxed as ordinary income. Bad for you.
- Non-compete agreements are taxed as ordinary income on your side. Also bad.
- Inventory is taxed as ordinary income. Same story.
A buyer who pushes heavy allocation into non-competes and equipment is, effectively, shifting your tax burden upward. This is a real negotiation point, not just paperwork.
The buyer wants the opposite. High allocation to depreciable assets means they can write those amounts off faster. Their interests and yours diverge directly here.

When we work with buyers at Regalis Capital, the purchase price allocation is part of the deal structure conversation, not an afterthought. As a seller, understanding this before you sign the letter of intent is critical. Once the LOI is signed, changing the allocation is difficult.
How SBA Deal Structure Affects Your Tax Picture
Most qualified buyers pursuing businesses in the $500K to $5M range are using SBA 7(a) financing. Sellers sometimes wonder if this changes their tax situation. In terms of capital gains, the financing method does not change your federal tax liability on the gain itself.
What does matter is how the total consideration is structured.
A typical SBA deal might look like this: 70% to 80% SBA loan, 10% buyer equity, and 10% to 15% seller note. That seller note means you do not receive all of your proceeds at closing. You receive a portion over time as the note is paid off.
The good news: this creates an opportunity for installment sale treatment under IRS rules. Rather than recognizing the entire gain in the year of sale, you can spread the gain across the years in which you receive payments. For sellers in high-income years, this can meaningfully reduce the tax hit.
But here is the thing most sellers miss about installment sales. The IRS requires that depreciation recapture is taxed in full in the year of sale, regardless of how payments are structured. Your CPA needs to run the installment sale analysis before you agree to the seller note terms.
One more thing about SBA deals (and this is specific to how we structure them at Regalis Capital): the seller note on most of our deals is structured on a 10-year full standby at 0% interest. Zero payments for up to a decade while the buyer services the SBA debt. That standby period affects the timing of your installment sale income recognition. Plan for it.
Stock Sale vs. Asset Sale: The Tax Difference
If you operate as a C-corporation, pay close attention here.
In a stock sale, you sell your shares in the company. The gain is typically treated as a long-term capital gain taxed at the rates described above. For sellers, this is usually the better tax outcome.
In an asset sale, the company sells its assets and you receive the proceeds through the corporation. If it is a C-corp, the company pays corporate tax on the gain first. Then when you distribute those proceeds to yourself as a shareholder, you pay personal capital gains tax again.
Double taxation. That is the real issue for C-corp sellers in asset sales.

Most buyers prefer asset sales. They get a stepped-up basis in the assets and avoid inheriting unknown liabilities. Most sellers, especially C-corp owners, prefer stock sales.
This tension is one of the most common sticking points in small business acquisitions. Some buyers will accept a stock sale if the seller adjusts the price to compensate for the buyer’s added risk. Others will not budge.
If you operate as an S-corp, LLC, or sole proprietorship, this issue is largely moot. Most of these deals close as asset sales without the double-taxation problem because the business income flows through to your personal return.
All of That Covers the Mechanics. Now Here Is What You Can Actually Do About It.
You have some legitimate tools available. Worth knowing before you sign anything.
Qualified Small Business Stock (QSBS) Exclusion: If your business is a C-corporation and meets certain criteria under Section 1202, you may be able to exclude up to $10M in capital gains. The rules are strict, including a five-year holding requirement. Ask your attorney and CPA if you qualify.
Opportunity Zone Reinvestment: Reinvest your capital gains into a Qualified Opportunity Zone fund within 180 days of the sale, and you can defer and potentially reduce your federal capital gains tax. This works best for sellers who plan to redeploy capital rather than take it off the table.
Charitable Remainder Trust (CRT): Sellers who want to benefit charity can contribute business interests to a CRT before the sale. The trust sells the business tax-free and pays you income over time. The charitable deduction and deferred income can significantly reduce your bill.
Installment Sale: As mentioned, structuring part of your proceeds as a seller note can spread the gain over multiple years. This strategy works best when the installment payments keep you in a lower bracket year over year.
None of these are simple. All of them require professional guidance. The point is that capital gains tax on selling a business is not a fixed number. It is a variable that depends on structure, timing, and planning.
What Buyers See When They Look at Your Numbers
This section matters because what a buyer pays, and how they structure the offer, directly affects your after-tax proceeds.
When we underwrite a deal at Regalis Capital, we are looking at seller discretionary earnings (SDE) or EBITDA depending on the size of the business. For most businesses in the $1M to $5M acquisition range, we work off SDE. The multiple we apply typically lands between 2.0x and 3.5x SDE. For EBITDA-based deals, the range is roughly 2.5x to 5.0x EBITDA, with most deals closing below 4.0x.

The point for sellers: the purchase price allocation and deal structure are not separate from the valuation conversation. A seller who understands how buyers build their offers can negotiate more effectively around the allocation, the seller note terms, and the non-compete structure. All of which affect after-tax proceeds.
A $1.5M purchase price structured one way might net you $900K after tax. Structured differently, it might net you $1.05M.
That $150K difference comes from the allocation, the installment sale treatment, and the non-compete carveout. Not from the headline number.
Sellers who work with brokers focused purely on maximizing the listing price sometimes miss this. The listing price and the after-tax proceeds are not the same thing. And honestly, from what we have seen across hundreds of deals, the sellers who focus too heavily on the top-line number often end up worse off after taxes than sellers who accepted a slightly lower price with better structure.
Frequently Asked Questions
What is the capital gains tax rate when selling a business?
For businesses held more than one year, the federal long-term capital gains rate is 0%, 15%, or 20% depending on your income. Most business sellers in the $1M to $5M transaction range pay 20% at the federal level plus a 3.8% Net Investment Income Tax, for an effective federal rate around 23.8%. State taxes vary and can add significantly to that total.
Does the way a buyer finances the deal affect capital gains tax on selling a business?
The financing method itself does not change your capital gains rate. However, if the deal includes a seller note, as most SBA-financed acquisitions do, you may qualify for installment sale treatment under IRS rules. This lets you spread the recognized gain across multiple years as payments come in, which can reduce your overall tax burden depending on your income in each year.
Is it better to do a stock sale or an asset sale for tax purposes?
From a tax standpoint, sellers generally prefer stock sales because the gain is treated as long-term capital gains taxed at lower rates. Asset sales can trigger depreciation recapture taxed at ordinary income rates and, for C-corporations, potential double taxation. Buyers typically prefer asset sales. This difference is a real negotiation point and often affects the final purchase price.
How does purchase price allocation affect taxes when selling a business?
The allocation of purchase price across assets determines how each portion is taxed. Goodwill is typically taxed at capital gains rates, which is favorable for sellers. Amounts allocated to non-compete agreements and depreciable equipment are often taxed as ordinary income, which is less favorable. Sellers should negotiate allocation terms carefully, as this directly impacts after-tax proceeds.
Can I avoid capital gains tax when selling my business?
You likely cannot avoid it entirely, but you can reduce it. Strategies include installment sale treatment through a seller note, Qualified Small Business Stock exclusion for eligible C-corp shareholders, Opportunity Zone reinvestment, and Charitable Remainder Trusts. Each strategy has specific eligibility rules and trade-offs. Work with a CPA who specializes in business transactions before signing any purchase agreement.
