Do I Pay Taxes on Sale of Business? Federal + State Tax Breakdown (2026)

Do I pay taxes on sale of business? Yes, and the question is not whether but how much, with effective rates ranging from roughly 24% to 37% on the gain depending on entity type, deal structure, state of residence, and whether you use any of the four legitimate zero-tax strategies covered below. The average $5M asset sale of an S-corp produces about $1.5M in combined federal and state tax, or roughly 30% of the gain.

Context: Why This Question Matters

Most sellers fixate on headline price and ignore net proceeds until the closing statement lands. That is backwards. A $5M sale in Texas can leave the owner with $3.8M after tax, while the identical deal in California leaves $3.14M. The same $5M sold as a C-corp asset deal versus an S-corp asset deal can swing net proceeds by $400K to $600K because of the double tax exposure.

Sellers who walk into a sale without modeling the after-tax outcome routinely discover the bill at the wrong moment. The IRS treats different parts of a single deal under different rules, so the headline price obscures the actual answer. Knowing what gets taxed at ordinary rates versus capital gains rates is the difference between a sale that funds retirement and one that funds a smaller retirement than expected.

The Detailed Answer

The federal tax on a business sale breaks into two buckets. The capital gain portion (goodwill, going-concern value, customer relationships, trademarks, and other intangibles created by the owner) is taxed at the long-term capital gains rate, currently 20% for sellers in the top bracket, plus the 3.8% Net Investment Income Tax (NIIT) under IRC Section 1411 for sellers above the threshold. That puts the federal capital gains rate at 23.8% for most owners selling a meaningful business.

The ordinary income portion is everything else. Inventory is ordinary. Working capital adjustments are ordinary. Non-compete payments are ordinary under IRC Section 197. Depreciation recapture on equipment under IRC Section 1245 is ordinary up to the amount of depreciation previously taken. Real estate depreciation recapture under IRC Section 1250 is taxed at a special 25% federal rate. These ordinary components sit at the seller’s marginal rate, typically 22% to 37% federal for individual sellers receiving pass-through income.

The IRS forces sellers and buyers to allocate the purchase price across asset classes on Form 8594, governed by IRC Section 1060. This allocation is the single most important tax decision in the deal, and it is negotiated, not automatic. Sellers want more allocation to goodwill (capital gains) and less to non-compete, inventory, and equipment (ordinary). Buyers want the opposite because their deductions accelerate. The allocation is binding on both parties for tax purposes, so the LOI and definitive agreement should pin it down before signing.

State tax is the second bucket and is often underestimated. California taxes the entire gain at 13.3% top rate with no special capital gains treatment. New York is 10.9%. New Jersey is 10.75%. Oregon, Minnesota, and Hawaii cluster between 9.85% and 11%. Florida, Texas, Nevada, Washington, Tennessee, South Dakota, and Wyoming have zero state income tax on the gain.

Entity type determines whether you pay once or twice. S-corps, LLCs taxed as partnerships, and sole proprietorships are pass-through and produce one layer of tax at the owner level. C-corps produce two layers: the corporation pays corporate tax (21% federal) on the asset sale gain, then the shareholder pays a second tax on the dividend or liquidation distribution. The total effective rate on a C-corp asset sale can exceed 45% federal before state tax, which is why most C-corp sellers push for a stock sale or use a Section 338(h)(10) election to convert a stock sale into an asset sale for tax purposes without triggering the double tax.

Earnouts and installment payments receive favorable treatment under IRC Section 453. Capital gain is recognized as payments are received, not at closing, which spreads the tax bill across multiple years and can keep the seller below NIIT thresholds in some years. Interest on the deferred portion is ordinary. The trade-off is collection risk: if the buyer underperforms or defaults, the seller still owes tax on payments already received but may not receive future payments.

Worked Example: $5M S-Corp Asset Sale

Consider a real-world allocation for a $5M asset sale of an S-corp owned by a Texas resident with full basis recovery on equipment:

Net to the Texas seller: $3.8M, or 76% of the headline price. Source for federal rates: IRC Sections 1001, 1060, 1245, 1250, 1411; IRS Publication 544.

The identical deal closed by a California resident adds 13.3% state tax on the full $5M gain, or approximately $665K, bringing the total tax to $1.86M and net proceeds to $3.14M, or 63% of headline. The state of residence at the closing date is the deciding factor, not where the business operates, although California aggressively pursues former residents who relocate shortly before closing.

Four Strategies That Reduce or Eliminate the Tax

QSBS exclusion under IRC Section 1202. Owners of qualifying C-corps held for more than five years can exclude up to $10M of federal gain (or 10 times basis, whichever is greater) from capital gains tax. The corporation must have had gross assets under $50M when stock was issued and must conduct an active trade or business in a qualifying field (most operating businesses qualify; investing, farming, hospitality, and certain professional services do not). For a founder with $10M of QSBS gain, this is a $2.38M federal tax savings.

ESOP rollover under IRC Section 1042. An owner selling at least 30% of a C-corp to an Employee Stock Ownership Plan can defer capital gains indefinitely by reinvesting proceeds into qualified replacement property (typically domestic corporate stocks and bonds) within 12 months. The deferral persists until the replacement property is sold, and a step-up at death can eliminate the gain entirely. Best fit for owners who want to exit gradually and care about employee continuity.

Opportunity Zone investment under IRC Section 1400Z-2. Capital gains reinvested into a Qualified Opportunity Fund within 180 days defer recognition until December 31, 2026 (the statutory deferral end date), and any new appreciation in the QOF held for 10 years or more is permanently excluded from federal tax. This is a deferral plus a partial exclusion, not a full elimination of the original gain.

Charitable Remainder Trust. Contributing stock or assets to a CRT before sale converts the seller into an income beneficiary, with the trust selling the asset tax-free and paying the seller a stream of income over a term of years or life. The seller takes an immediate charitable deduction for the present value of the remainder interest. The trade-off is irrevocability and the loss of principal to charity at the end of the term.

What Most Owners Get Wrong

Misconception 1: “I sold the stock so it is all capital gain.” Only true for C-corp stock sales where the seller has no inventory, no Section 1245 property recapture, and no installment interest income. For S-corps, the asset character carries through to the shareholder even in a stock sale if the buyer elects Section 338(h)(10), which most strategic buyers do.

Misconception 2: “I’ll move to Florida before closing and skip the state tax.” California, New York, and New Jersey audit relocations of high-income residents around liquidity events. They look at where you spent the majority of the year, where your driver’s license and voter registration are, where your spouse and children live, and where your medical care is delivered. A six-month relocation right before closing rarely survives audit. A genuine 18-to-24-month relocation usually does.

Misconception 3: “The buyer’s allocation request does not affect me.” The Form 8594 allocation is jointly filed and binding on both parties under IRC Section 1060. If the buyer files an allocation that puts $500K to non-compete and you file the same deal with $500K to goodwill, the IRS reconciles the mismatch, usually against the seller. The allocation belongs in the LOI, not in a post-closing scramble.

How CT Acquisitions Approaches This

CT Acquisitions is a buyer-paid M&A advisor. Buyers pay us, not you, which removes the conflict of interest that plagues traditional brokerages. Most brokers want the highest headline price because their commission scales with it; they do not get paid more when the seller keeps more after tax. Our model aligns differently: we model net proceeds before the LOI is signed, push the allocation that maximizes seller capital gain treatment, and surface QSBS, ESOP, and installment options when they fit the seller’s situation.

Owners who engage us early get a pre-LOI tax model showing federal, state, and effective rate scenarios across asset sale, stock sale, and 338(h)(10) structures. That model becomes the negotiating posture with the buyer. Owners who come to us with an LOI already signed have less room to move the allocation, but we can still optimize installment terms, earnout structure, and closing-date timing to reduce the bill.

Related Questions

How much tax do I pay if I sell my business for $1 million?

For a $1M asset sale of an S-corp with typical allocation (60% goodwill, 20% equipment, 10% inventory, 10% working capital), expect roughly $240K to $290K federal tax in a no-state-tax state, or $340K to $390K in California. Effective rate sits around 24% to 29% federal and 34% to 39% combined.

Do I pay capital gains on the sale of an LLC?

Yes. LLCs taxed as partnerships or disregarded entities pass the gain through to the owner, where it splits between capital gain (intangibles, goodwill) and ordinary income (inventory, recapture, non-compete) under the same IRC Section 1060 allocation rules that apply to S-corps and sole proprietors.

Can I avoid taxes by selling my business through an installment sale?

No, you cannot avoid the tax, but you can defer it. IRC Section 453 lets the seller recognize gain as payments are received rather than all at closing. The total tax is the same, but spreading it over five to ten years can keep the seller in lower brackets and below NIIT thresholds in some years. Interest on the deferred balance is ordinary income.

What is the difference between an asset sale and stock sale for taxes?

In an asset sale, the seller pays a blended rate across capital gains and ordinary income components, while the buyer gets a stepped-up basis and accelerated depreciation. In a stock sale, the seller usually pays pure capital gain (lower tax), but the buyer inherits historical basis (worse tax position). Buyers pay 5% to 15% more for asset sales to compensate the seller for the higher tax. The 338(h)(10) election is the compromise: legally a stock sale, tax-wise an asset sale.

Do I pay tax on the goodwill portion of a business sale?

Yes, but at the long-term capital gains rate (currently 20% federal plus 3.8% NIIT = 23.8% for top-bracket sellers) rather than the ordinary income rate. Personal goodwill, when the seller can establish it is tied to the individual rather than the entity, can sometimes be sold directly by the shareholder in a C-corp deal, avoiding the double tax entirely. The Martin Ice Cream and Bross Trucking cases established this doctrine.

What to Do Next

The tax model belongs in the conversation before the LOI is signed, not after. Owners who wait until due diligence to model the after-tax number routinely discover the structure they agreed to leaves $200K to $700K on the table. The fix is straightforward: model federal, state, and entity-level outcomes across two or three deal structures before any term sheet is countersigned.
