Introduction
The number on your purchase agreement is not what lands in your bank account. Between transaction costs, debt payoff, escrow holdbacks, and taxes, many owners find their take-home well below the headline sale price.
What you actually owe depends on several variables:
- Your business entity type
- Asset sale vs. stock sale structure
- Adjusted tax basis in the business
- How the purchase price is allocated across asset categories
- Timing of payment and your federal and state tax situation
This article shows how to estimate taxable gain, compare deal structures, spot planning opportunities, and know what to review before you sign a letter of intent or purchase agreement.
Key Takeaways
- You owe tax on taxable gain, not the headline sale price—and deal parts can be taxed differently.
- Asset sales often produce a blend of capital gain, ordinary income, and depreciation recapture.
- Purchase-price allocation, seller notes, earnouts, and state taxes all affect timing and amount owed.
- Model after-tax proceeds with a qualified tax professional before signing anything binding.
What Taxes Apply When Selling a Business?
Start with the formula that determines your tax bill: consideration received, minus adjusted basis, minus eligible transaction costs, equals taxable gain. That gain, not your gross sale price, is what gets taxed.
Not every dollar of gain is treated the same way. These items generally produce ordinary income, not capital gain:
- Inventory and accounts receivable
- Consulting or non-compete agreement payments
Depreciation recapture is also taxed as ordinary income, regardless of how long you held the asset.
Federal Rate Brackets to Know
For the 2026 tax year, long-term capital gain is taxed at 0%, 15%, or 20%, depending on your taxable income and filing status, according to IRS guidance on 2026 inflation adjustments.
| Rate | Single filers | Married filing jointly |
|---|---|---|
| 0% | Up to $49,450 | Up to $98,900 |
| 15% | $49,450–$545,500 | $98,900–$613,700 |
| 20% | Above $545,500 | Above $613,700 |
Ordinary-income brackets run from 10% to 37% for 2026. The portion of your gain characterized as ordinary income (inventory, recapture, consulting pay) could land in the 24% or even 37% bracket depending on your total income.
The Net Investment Income Tax (NIIT) adds a 3.8% tax on investment income once your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly), per the IRS's NIIT guidance. Whether it applies to your sale depends on your entity type and level of participation in the business.
State taxes add another layer. States like Virginia tax capital gain as ordinary income under their own schedules, so your true liability combines federal and state exposure.
Asset Sale vs. Stock Sale: Why Structure Matters
This single decision shapes almost everything else about your tax outcome.
Asset sale: The buyer purchases specific assets, including equipment, inventory, contracts, customer relationships, intellectual property, and goodwill. Each category gets its own tax treatment:
- Inventory produces ordinary income
- Equipment may trigger depreciation recapture
- Goodwill often qualifies for capital gain treatment, depending on personal vs. corporate goodwill
Stock or equity sale: The buyer acquires ownership interests directly. You calculate gain at the owner level, based on your equity's adjusted basis and how long you've held it. This tends to produce a cleaner, single capital-gain calculation rather than a mix of income characters.
Buyer and Seller Pull in Different Directions
- Buyers often prefer asset purchases because they get a stepped-up basis in acquired assets, unlocking future depreciation or amortization deductions.
- Sellers often prefer stock sales for simpler, owner-level tax treatment and to sidestep certain corporate-level consequences.
This tension is exactly why structure gets negotiated, not assumed.
Why C Corporations Need Extra Scrutiny
C corporation owners face a distinct risk in asset sales: the corporation itself can owe tax on the sale, and then shareholders can owe tax again when proceeds get distributed. A direct stock sale avoids this double layer. Given the federal corporate rate sits at 21%, this compounding effect can erode proceeds substantially. A tax adviser should model both paths before you commit.
LLCs, Partnerships, and S Corps Aren't One-Size-Fits-All
LLC, partnership, and S corporation transactions can involve pass-through reporting, deemed asset treatment, or other entity-specific quirks. Partnership interests, for example, are typically capital gain at the owner level, except for the portion tied to "hot assets" like unrealized receivables and inventory, which stays ordinary income.
There's no universal answer here; the right structure depends on your specific entity history.
At Mid Atlantic Business Brokers, we help sellers work through confidential valuation, buyer negotiations, and deal-structure discussions as these decisions take shape. Your CPA and attorney ultimately confirm the tax and legal consequences of any given structure.
How to Calculate Capital Gains on the Sale of a Business
Here's a simplified, illustrative example, not a prediction of your actual tax bill.
| Item | Amount |
|---|---|
| Consideration received | $2,000,000 |
| Less: adjusted basis | $600,000 |
| Less: eligible transaction costs | $100,000 |
| Taxable gain | $1,300,000 |
That $1,300,000 then gets split by character: roughly $900,000 in long-term capital gain, $250,000 in depreciation recapture, and $150,000 in ordinary income from inventory and a consulting payment. Each piece faces a different rate.
Building Your Adjusted Basis
Your adjusted basis starts with your original investment and changes over time. It typically reflects:
- Original capital contributions
- Later capital contributions or additional paid-in capital
- Prior depreciation deductions (which reduce basis)
- Distributions taken over the years
- Entity-level adjustments your CPA reconstructs from historical records
Older businesses often need extra work to rebuild that basis trail before you model the gain.
Purchase-Price Allocation and Form 8594
When a transaction involves a mix of assets, buyer and seller generally report an agreed allocation on IRS Form 8594.
The form groups assets into classes:
- Cash and securities
- Receivables and inventory
- Other tangible assets
- Intangibles
- Goodwill and going-concern value (the residual)
Where the dollars land in this allocation directly changes your blended tax result.
Goodwill and going-concern value represent whatever business worth is left over after everything else is accounted for. Whether that goodwill is treated as self-created, acquired, or personal to you as an individual can change its tax treatment substantially. That treatment is fact-specific, so your CPA should verify it for your deal.
Other Considerations That Change the Math
The form of payment matters as much as the amount:
- Seller notes spread out payment, and potentially tax recognition, over time
- Earnouts tie part of your proceeds to future performance, adding uncertainty
- Rollover equity defers some gain but keeps you exposed to the buyer's future success
- Assumed liabilities, escrow, and working-capital adjustments can raise or lower net proceeds after the headline price
Model each one before you accept an offer. A seller note that looks generous on paper can carry real credit risk if the buyer's business underperforms.
Planning Strategies to Review Before Signing
Tax planning works best before you sign a letter of intent (LOI). Once terms are set, allocation principles, payment structure, and buyer economics become difficult or expensive to unwind.
Negotiate the Allocation, Don't Default to It
Push for a purchase-price allocation backed by supportable fair market values, ideally with a professional valuation behind it. Buyer and seller reporting should be consistent. Simply assigning value to whatever category is most tax-favorable for you invites IRS scrutiny and buyer pushback.
Installment Sales Can Spread Recognition
Under Section 453, eligible gain can be recognized as payments arrive rather than all at once, using a gross-profit percentage. But there are limits:
- Inventory gain can't be deferred this way
- Depreciation recapture is reported in the year of sale, regardless of when cash arrives
- Sales to related parties face acceleration rules if the buyer resells too soon
QSBS: A Narrow but Powerful Option
If your business is a qualifying C corporation and your stock was originally issued directly to you, Section 1202's qualified small business stock exclusion may apply.
Under the 2025 law changes, stock acquired after July 4, 2025, can qualify for a 50%, 75%, or 100% exclusion depending on a 3-, 4-, or 5-year hold, with a fixed-dollar exclusion component raised to $15 million, according to the 2025 tax legislation text.
Eligibility is highly fact-specific. Original issuance, business activity, and asset limits all matter, and your state may not conform to this federal exclusion.
State Tax Planning Needs Early Attention
State sourcing and residency rules can diverge sharply from federal treatment. Relocating before a sale isn't a simple or guaranteed strategy, and the timing matters enormously. Get state-specific advice early, not after the deal closes.
A Practical Planning Timeline
- Well before going to market: Reconstruct basis and entity history
- Before signing an LOI: Model alternative structures and their tax outcomes
- During diligence: Review allocation language and payment terms closely
- After closing: Coordinate reporting and any estimated tax payments
Mistakes, Preparation, and Professional Help
Common Mistakes Sellers Make
- Applying one flat tax percentage to the entire sale price
- Assuming every dollar of proceeds is capital gain
- Overlooking depreciation recapture until it's too late to plan around
- Ignoring state tax exposure entirely
- Accepting the buyer's proposed allocation without modeling it themselves
- Waiting until closing week to bring in tax advice
A Seller Preparation Checklist
Before you go to market, gather:
- Prior tax returns, typically the last three years
- Depreciation schedules for all business assets
- Ownership and capital-contribution records
- Debt and lien documentation
- Entity formation documents
- Current financial statements
- Any draft LOI or purchase agreement already in hand
Addressing tax issues late in the process can limit which options remain available. This groundwork matters as much as the eventual negotiation.
A confidential valuation and sell-side process helps you understand what your business is actually worth, evaluate competing buyer proposals, and estimate after-tax proceeds before you're locked into terms.
At Mid Atlantic Business Brokers, our valuation work follows USPAP standards and draws on over 40 years of data-driven analysis across retail, healthcare, manufacturing, and technology. That context helps you read the deal clearly, but it does not replace tax advice specific to your situation.

Frequently Asked Questions
How much capital gains tax will I pay when I sell my business?
It depends on your taxable gain, adjusted basis, entity type, sale structure, asset allocation, ordinary-income items, and both federal and state taxes. Get a transaction-specific calculation from a tax professional rather than estimating with a flat percentage.
How do I calculate capital gains on the sale of my business?
Start with consideration received minus adjusted basis and eligible transaction costs. For an asset sale, each asset category needs separate analysis; for a stock sale, you'll need your equity basis and holding period.
Is capital gains tax 20% or 24%?
Neither number applies universally. Long-term capital gains top out at 20% federally, while 24% is an ordinary-income bracket — your actual rate depends on gain character, recapture, NIIT exposure, and state taxes.
