Can You Sell Your Business If You're a Corporation?
Yes, you can sell your corporation through either a stock sale or an asset sale. The entity type — C-corp versus S-corp — determines whether you face double taxation at a combined 39.8% rate or single taxation at 23.8%. Two powerful tax elections change the equation: a § 338(h)(10) election lets S-corp sellers achieve asset sale tax treatment in a stock sale, and § 1202 QSBS exclusion can eliminate federal capital gains tax entirely for qualifying C-corp shareholders.
Key Takeaways
- C-corp asset sales trigger double taxation at a combined 39.8% effective federal rate, costing significantly more than S-corp structures. 1
- The § 338(h)(10) election lets S-corp stock sales be treated as asset sales for tax, giving buyers a stepped-up basis. 3
- QSBS under § 1202 can exclude up to $10M in capital gains for qualifying C-corp shareholders who held stock five-plus years. 2
- Buyers prefer asset sales for the stepped-up basis, while sellers prefer stock sales for capital gains treatment. 4
- Lower middle market corporations typically sell at 4.0–6.0x EBITDA, with S-corps commanding a structural premium due to tax efficiency. 5
How Does Corporate Structure Affect Selling Your Business?
This condition doesn't make your business unsellable — but it does change the math. Here are the primary ways it impacts your transaction.
Double Taxation Risk for C-Corps
C-corp asset sales generate tax at two levels: 21% corporate tax on gains, then 23.8% shareholder tax on distributions. On a $3M gain, the combined federal tax is approximately $1.19M — a 39.8% effective rate that can eliminate a third of your proceeds. 1Stock Sale vs. Asset Sale Tension
Sellers want stock sales for capital gains treatment. Buyers want asset sales for the stepped-up basis that enables future depreciation deductions. This fundamental conflict shapes every corporate sale negotiation and often results in purchase price adjustments of 10–15%. 4Section 338(h)(10) Bridge Election
For S-corps, the § 338(h)(10) election resolves the buyer-seller conflict by treating a stock purchase as a deemed asset sale for tax purposes. The buyer gets stepped-up basis, the seller gets pass-through treatment at 23.8%. Both parties file Form 8023 within nine months. 3QSBS Exclusion Potential
C-corp shareholders who acquired stock at original issuance, held it five-plus years, and meet the $50M gross asset test can exclude up to $10M in gains under § 1202. Post-July 2025, the OBBBA raised the cap to $15M and the asset threshold to $75M. 2Asset Sale vs. Stock Sale: How Corporate Structure Changes the Equation
| Factor | Asset Sale | Stock Sale |
|---|---|---|
| Tax treatment (C-Corp) | Double taxation: 21% corporate + 23.8% shareholder = 39.8% combined 1 | Single layer: 23.8% capital gains on shareholder gain 1 |
| Tax treatment (S-Corp) | Pass-through: mixed ordinary and capital gains at shareholder level | Pass-through: 23.8% capital gains on entire gain |
| Buyer basis step-up | Yes — buyer depreciates and amortizes at purchase price 8 | No — buyer inherits historical basis (unless § 338 election) |
| Liability transfer | Buyer generally does not inherit liabilities 7 | Buyer inherits all liabilities, known and unknown |
| § 338(h)(10) availability | Not applicable — already an asset sale | S-corp and consolidated group only — deemed asset sale for tax 3 |
| QSBS eligibility (§ 1202) | Not applicable — QSBS requires stock sale 2 | C-corp only — up to $10M exclusion with five-year hold 2 |
| Frequency in market | 70–80% of lower middle market deals 4 | 20–30% of deals; more common in larger transactions |
| Best when | Buyer wants clean assets and step-up; seller is S-corp | QSBS applies, or seller wants maximum capital gains treatment |
What Are the Tax Differences Between C-Corp and S-Corp Sales?
Not every situation is treated the same. Each type has different transfer rules, timelines, and risks that affect your sale.
C-Corp Asset Sale
Transfer Rule
Corporation sells assets, pays corporate tax, then distributes remaining proceeds to shareholders who pay a second tax
Typical Handling
Most common buyer preference due to basis step-up; worst outcome for C-corp sellers
Timeline
45–90 days from LOI to close
Watch Out
Combined 39.8% effective rate destroys nearly $4 of every $10 in gain — model this before agreeing to structure. 1C-Corp Stock Sale
Transfer Rule
Shareholders sell shares directly to buyer; single capital gains tax at 23.8%
Typical Handling
Sellers strongly prefer; buyers resist due to inherited liabilities and no basis step-up
Timeline
60–120 days due to extended due diligence on liabilities
Watch Out
Buyers typically demand a 10–15% price discount to compensate for lost basis step-up and inherited liability risk. 4S-Corp with § 338(h)(10)
Transfer Rule
Stock sale legally, but deemed asset sale for tax — buyer gets step-up, seller gets pass-through at 23.8%
Typical Handling
Gold standard for S-corp sales; requires 80% stock acquisition and all shareholders to consent
Timeline
45–90 days; Form 8023 filed within 9 months post-close
Watch Out
PE buyers using LLC acquisition vehicles do not qualify as the purchasing corporation — consider F-Reorganization as alternative. 3C-Corp with QSBS (§ 1202)
Transfer Rule
Stock sale with 100% federal capital gains exclusion on qualifying shares up to $10M (or $15M post-OBBBA)
Typical Handling
Best possible outcome for qualifying C-corp shareholders; requires original issuance, five-year hold, and sub-$50M assets at issuance
Timeline
60–90 days; QSBS qualification confirmed pre-close
Watch Out
Qualification is binary — if gross assets exceeded $50M at any point during issuance period, the exclusion is completely lost. 2C-to-S Conversion Sale
Transfer Rule
Convert to S-corp, wait five years for BIG tax period to expire, then sell with pass-through treatment
Typical Handling
Long-term planning strategy only; requires five-year patience for full benefit under § 1374
Timeline
Five-year minimum from conversion to avoid BIG tax
Watch Out
Assets appreciated at conversion date face 21% BIG tax if sold within the recognition period — partial benefit may still be worthwhile. 1How to Sell Your Corporation: Step-by-Step
Determine Your Corporate Tax Classification and History
Confirm whether your entity is a C-corp or S-corp and review your election history. If you converted from C to S, the five-year built-in gains recognition period under § 1374 must have expired, or gains on appreciated assets will face the 21% BIG tax. This single determination drives every subsequent decision.
Pro tip: Request a tax status letter from your CPA confirming S-election date and BIG tax exposure before engaging any buyer. 1
Evaluate QSBS Eligibility for C-Corp Shareholders
If you are a C-corp, assess whether your stock qualifies under § 1202. Requirements include original issuance acquisition, five-year holding period, active qualified business, and gross assets under $50M at issuance. A qualifying QSBS exclusion can save millions in federal tax and fundamentally changes whether a stock sale or asset sale is preferable.
Pro tip: QSBS qualification is determined at issuance date, not sale date — gather founding-era corporate records to confirm gross asset threshold. 2
Model the Tax Outcomes for Each Deal Structure
Run detailed tax projections for every viable scenario: C-corp asset sale, C-corp stock sale, C-corp stock with QSBS, S-corp stock sale, and S-corp with § 338(h)(10). Include state taxes, depreciation recapture, and the § 1060 allocation. The spread between worst and best case on a $20M deal can exceed $7M in tax savings.
Pro tip: The § 1060 residual allocation method assigns purchase price across seven asset classes — negotiate Class VII goodwill allocation to maximize capital gains treatment. 8
Prepare Corporate Governance and Compliance Documentation
Assemble articles of incorporation, bylaws, board resolutions authorizing the sale, shareholder consents, certificate of good standing, and all stock transfer ledgers. Buyers performing due diligence on a corporation scrutinize governance documents intensely because gaps suggest hidden liabilities or ownership disputes.
Pro tip: File for a certificate of good standing from your Secretary of State at least 30 days before marketing — lapses delay closing. 6
Negotiate Structure, Price, and the Section 338 Election
Use your tax modeling to drive negotiations. S-corp sellers should propose § 338(h)(10) as a win-win: buyers get stepped-up basis, sellers get pass-through treatment. C-corp sellers with QSBS should insist on stock sales. Build the tax savings into the purchase price negotiation rather than leaving them on the table.
Pro tip: Form 8023 for the § 338(h)(10) election must be filed by the 15th day of the 9th month after the acquisition date — calendar this immediately at closing. 3
What Are the Biggest Risks of Selling a Corporation?
C-Corp Double Taxation Trap
The 39.8% combined federal rate on C-corp asset sales is the single largest value destroyer in corporate transactions. On a $20M deal, this means $7.96M in total federal tax versus $4.76M for an S-corp — a $3.2M difference driven entirely by entity classification. [1]
Built-In Gains Tax Window
Owners who converted from C-corp to S-corp face the § 1374 built-in gains tax at 21% on appreciated assets if sold within five years of conversion. This trap catches sellers who convert hoping for S-corp treatment and then sell too quickly, resulting in an unexpected tax layer.
Buyer Due Diligence Complexity
Corporate sales require extensive governance review: stock ledgers, board minutes, shareholder agreements, and state filings must all be current and consistent. Missing or incomplete corporate records raise red flags about unknown liabilities and can delay closing by 30–60 days. [6]
Shareholder Alignment Requirement
All shareholders must consent to a § 338(h)(10) election, and board approval is required for the sale itself. Minority shareholders who disagree on deal structure or price can trigger appraisal rights, delaying or derailing the transaction entirely. [3]
What Corporate Sale Red Flags Make Buyers Walk Away?
Knowing what buyers scrutinize helps you prepare. Address these before going to market.
Missing or incomplete stock transfer ledger
An incomplete stock ledger suggests unknown shareholders or unrecorded transfers. Buyers cannot close without confirming who owns 100% of the equity, and gaps here can indicate unresolved ownership disputes that could void the transaction.
C-corp insisting on asset sale without tax modeling
A C-corp seller pushing for an asset sale suggests a lack of sophisticated tax advice. Buyers worry about encountering other financial planning gaps and question whether the seller understands the 39.8% effective rate they are accepting.
Recent C-to-S conversion within five years
If the S-election is less than five years old, the § 1374 built-in gains tax applies to appreciated assets at 21%. This hidden tax layer reduces net proceeds and complicates the deal structure for both parties.
Shareholder disputes or minority holdouts
Minority shareholders who oppose the sale or the chosen deal structure can exercise appraisal rights, refuse § 338 consent, or file litigation. These disputes delay closing and create uncertainty buyers actively avoid.
Expired corporate good standing or missing annual filings
Lapsed state filings suggest operational disorganization and can create successor liability risks. Reinstatement requires time and fees, and some states impose back taxes and penalties that reduce net proceeds.
No formal board minutes authorizing major decisions
Absent corporate governance records suggest the corporation has been run as a sole proprietorship in corporate clothing. Buyers worry about personal liability bleed-through and challenge whether the corporate veil provides any real protection.
How Is a Corporation Valued for Sale?
Corporate valuation depends on entity type, which directly determines the after-tax proceeds to shareholders.
EBITDA

Lower middle market manufacturing

Pre-tax deal value
− C-Corp Double Tax (39.8%)
21% corporate + 23.8% shareholder
= C-Corp Net to Seller
Worst case: C-corp asset sale
vs. S-Corp Net (23.8% tax)
S-corp saves $3,040,380
Key insight: The entity-driven tax gap on a $20M sale is $3.04M in additional federal taxes for a C-corp asset sale versus an S-corp stock sale. This is why entity classification is arguably the most consequential decision an owner makes before a liquidity event. QSBS-eligible C-corp owners can flip this equation entirely, potentially paying zero federal tax on qualifying gains. [1][2]

I have seen C-corp owners leave millions on the table simply because nobody modeled the tax difference between a stock sale and an asset sale before they signed the LOI. The time to plan your entity-level tax strategy is before you go to market, not at the closing table.

Key Lessons
- QSBS eligibility analysis was performed first, confirming stock held eight years and gross assets were under $50M at issuance, but two shareholders did not meet the five-year hold. [2]
- The seller proposed a stock sale with § 338(h)(10) election as a compromise, giving the buyer stepped-up basis while preserving pass-through tax treatment for all shareholders. [3]
- Tax modeling showed the stock sale with § 338(h)(10) saved the seller $3.04M compared to a C-corp asset sale, funding the entire advisory fee several times over. [1]
- Board resolution and unanimous shareholder consent for the § 338 election were obtained during LOI stage to prevent last-minute holdouts from derailing the deal structure. [3]
How Does Corporate Entity Type Affect Taxes When Selling?
C-Corp Asset Sale — Double Taxation at 39.8%
The corporation pays 21% federal tax on gains from the asset sale. The remaining proceeds are then distributed to shareholders as a liquidating distribution, taxed at up to 23.8% (20% capital gains + 3.8% NIIT). This two-layer structure produces the highest effective rate of any entity type.
Example
On a $19M gain: $3,990,000 corporate tax, leaving $16,010,000 for distribution. Shareholder tax of $3,572,380 on the $15,010,000 net gain. Total federal tax: $7,562,380. 1Key point: The 39.8% combined rate means C-corp asset sales cost nearly twice the tax of S-corp sales on the same gain. 1
S-Corp Stock Sale — Pass-Through at 23.8%
S-corp shareholders pay a single layer of capital gains tax at up to 23.8% federal rate (20% + 3.8% NIIT). No corporate-level tax applies because S-corps are pass-through entities. The § 338(h)(10) election adds the buyer’s basis step-up benefit without changing the seller’s tax outcome.
Example
On a $19M gain: $4,522,000 shareholder tax at 23.8%. No corporate-level tax. Total: $4,522,000. Savings vs. C-corp asset sale: $3,040,380. 3Key point: The § 338(h)(10) election achieves asset sale economics for the buyer while preserving pass-through treatment for the seller. 3
C-Corp Stock Sale with § 1202 QSBS Exclusion
Qualifying C-corp shareholders exclude 100% of capital gains up to the greater of $10M or 10x adjusted basis per issuer. Stock must be acquired at original issuance, held for five-plus years, with issuer gross assets under $50M at issuance. The exclusion applies per taxpayer, so married couples filing jointly can each claim it.
Example
On $10M of qualifying QSBS gain: $0 federal tax. On remaining $9M: $2,142,000 at 23.8%. Total: $2,142,000 versus $7,562,380 for an asset sale. 2Key point: Post-OBBBA, the exclusion cap rises to $15M and the gross asset threshold to $75M for stock issued after July 2025. 2
