Do You Have to Pay Taxes If You Sell a Company? Federal, State, and Structure Explained (2026)

Do you have to pay taxes if you sell a company? Yes, almost always, but the rate and timing vary dramatically by deal structure, entity type, and state. On a $25M sale, a C-corp owner with no planning can net around $14M after federal and state tax, while an S-corp owner using Section 1202 QSBS rules can keep $20M to $25M of the same headline price.

Context: Why This Question Matters

Most first-time sellers anchor on the headline number their banker or broker quotes them. The check that actually clears, after federal capital gains, state income tax, depreciation recapture, and any double tax on a C-corp, is often 30 to 45 percent smaller. The IRS treats a business sale as a taxable event under Section 1001 of the Internal Revenue Code, and there is no general exemption for selling the company you built.

What changes is the rate. A poorly structured C-corp asset sale in California can hit a combined effective rate over 50 percent. A well-structured S-corp stock sale in Texas with Qualified Small Business Stock treatment can hit zero. The difference between those two outcomes on a $20M deal is roughly $10M of personal wealth, all driven by decisions made 6 to 60 months before the closing date.

The Detailed Answer

Three variables drive the answer to whether and how much you pay when you sell a company: deal structure, entity type, and state of residence at closing.

Variable 1: Asset sale versus stock sale. In an asset sale, the buyer purchases specific assets (equipment, inventory, goodwill, intangibles) and the seller allocates the purchase price across those asset classes under IRS Form 8594. Goodwill and going-concern value generate long-term capital gains, taxed at 20 percent federally for high earners. Depreciation recapture on Section 1245 property (equipment, vehicles, software) is taxed at ordinary rates up to 37 percent. Section 1250 real property recapture is capped at 25 percent. Per IRS Publication 544, the allocation is binding on both buyer and seller for tax purposes.

In a stock sale, the buyer purchases the equity of the entity. The seller treats the entire gain as long-term capital gain (assuming the stock was held more than 12 months), generally taxed at 20 percent federal plus the 3.8 percent Net Investment Income Tax under Section 1411 for high earners. Buyers usually resist stock sales because they inherit known and unknown liabilities and lose the step-up in asset basis they would get in an asset deal. Per the Pratt’s Stats deal database, roughly 70 percent of private lower-middle-market deals close as asset sales for this reason.

Variable 2: Entity type. A C-corporation faces two layers of tax in an asset sale. The corporation pays 21 percent federal corporate tax on the gain, then the shareholder pays up to 23.8 percent (20 percent capital gains plus 3.8 percent NIIT) on the distribution of the after-tax proceeds. The combined effective rate lands near 39.8 percent federal before any state tax. The major exception is Section 1202 Qualified Small Business Stock, which can exclude the greater of $10M or 10x the original basis from federal capital gains tax if the C-corp stock was held more than 5 years and the company qualified as a QSB (under $50M in gross assets when the stock was issued, active trade or business, not in a disqualified industry). QSBS is one of the most valuable planning tools in the code.

An S-corporation or LLC taxed as a partnership is a pass-through. The gain flows to the owner’s personal return once, taxed at 20 percent federal capital gains for goodwill and intangibles, ordinary rates for recapture and inventory. There is no entity-level federal tax. An S-corp selling stock can also elect Section 338(h)(10), which treats the stock sale as an asset sale for tax purposes, giving the buyer the asset step-up they want while the seller still signs one transaction. Most strategic and private equity buyers will require this election if the target is an S-corp.

Variable 3: State tax. California taxes capital gains at ordinary rates up to 13.3 percent. New York hits 10.9 percent at the top bracket. New Jersey reaches 10.75 percent. Minnesota, Oregon, and Hawaii all clear 9 percent. Per the Tax Foundation 2026 state rate report, nine states have no income tax: Florida, Texas, Nevada, Washington, Tennessee, South Dakota, Wyoming, Alaska, and New Hampshire (which taxes interest and dividends only). State of residence is determined at the moment of closing, which is why some owners relocate to a no-tax state 12 to 24 months before signing an LOI. The IRS and aggressive state revenue departments do scrutinize residency changes timed to a liquidity event, so the move has to be real.

Worked Example: $10M Asset Sale of an S-Corp Manufacturer in Texas

Consider an owner-operator manufacturing business in Houston, organized as an S-corp, sold to a strategic buyer for $10M cash at closing. The Form 8594 allocation breaks down as: $7M goodwill and intangibles, $2M property and equipment (with $500K of accumulated depreciation since purchase), and $1M working capital (accounts receivable and inventory at book value).

Run the same deal in California and the seller adds roughly $1.13M of state tax (8.5M of capital gain plus 500K ordinary, all taxed at 13.3 percent), dropping net proceeds to around $6.78M. Same headline price, $1.13M difference, driven entirely by zip code.

Now run the same deal as a C-corp asset sale in California with no QSBS. The C-corp pays 21 percent federal plus 8.84 percent California corporate tax on the gain (roughly $2.98M), leaving $7.02M to distribute. The shareholder pays 23.8 percent federal plus 13.3 percent California on the distribution (roughly $2.6M), netting $4.42M. That is 44 percent erosion on the same $10M sale.

What Most Owners Get Wrong

Misconception 1: “Capital gains tax is 15 or 20 percent, so I’ll keep 80 percent.” That ignores the 3.8 percent NIIT, state income tax, depreciation recapture taxed at ordinary rates, and any C-corp double tax. The all-in effective rate on a typical private company sale runs 25 to 50 percent, not 20 percent. The 15 percent bracket only applies below roughly $501,600 of total taxable income for married-filing-joint, which most sellers blow past in the year of sale.

Misconception 2: “I’ll just sell stock and pay 20 percent.” Buyers will discount a stock deal by 10 to 25 percent of headline price to compensate for inheriting unknown liabilities and losing the asset step-up. The pre-tax gap often wipes out the post-tax savings, unless the seller has QSBS or another structural reason buyers will pay parity. The Section 338(h)(10) election bridges this for S-corps but accelerates the gain into the year of sale and can recharacterize portions as ordinary income.

Misconception 3: “I’ll move to Florida the month before closing and dodge state tax.” California, New York, and New Jersey have aggressive residency audit programs and apply a multi-factor domicile test (driver’s license, voter registration, primary residence, where your dog and accountant live, where you spent the most nights). A move 6 weeks before signing an LOI almost always fails. A move 18 to 24 months before, with a clean factual record, generally holds. The IRS and state authorities also apply “source income” rules to gain from in-state businesses, which can override residency in some cases.

How CT Acquisitions Approaches This

CT Acquisitions is a buy-side firm. Buyers pay our fee, sellers do not. That alignment matters here because traditional sell-side brokers earn a percentage of headline price, which gives them no incentive to optimize for the seller’s after-tax net. A broker is just as happy to close a $10M C-corp asset sale that nets the owner $5M as a $9M S-corp stock sale with a 338(h)(10) that nets $7M.

When we evaluate a target on behalf of an acquirer, we model both sides of the tax outcome and proactively structure offers (asset versus stock, 338 elections, earnout deferral, installment notes under Section 453, rollover equity) that maximize seller net while staying inside the buyer’s IRR. Sellers thinking about an exit in the next 12 to 36 months can book a free consultation to walk through their entity type, basis, and state situation before they sign anything binding.

How can I reduce or defer taxes when I sell my company?

Five tools cover most situations: Qualified Small Business Stock under Section 1202 (up to $10M federal exclusion for qualifying C-corp stock held 5+ years), installment sales under Section 453 (spreads gain over multiple tax years), Opportunity Zone investment (defers and partially eliminates gain rolled into a QOF within 180 days), ESOP rollover under Section 1042 (defers all gain when 30%+ sold to an employee stock ownership plan and proceeds rolled into qualified replacement property), and Charitable Remainder Trusts. See our deeper breakdown at how to avoid capital gains tax on a business sale.

Is the sale of a business considered ordinary income or capital gain?

Both, in most cases. Per IRS Form 8594, the purchase price is allocated across asset classes. Goodwill, going-concern value, customer lists, and most intangibles produce long-term capital gain. Inventory, accounts receivable, depreciation recapture on equipment, and any consulting or non-compete payments produce ordinary income taxed at rates up to 37 percent federally. The split typically lands 70 to 85 percent capital gain and 15 to 30 percent ordinary on a service or distribution business, with higher ordinary share when there is heavy depreciated equipment.

Do I pay taxes on the sale price or just the profit?

Just the profit, technically the gain over your tax basis. Basis is what you paid for the business or assets, plus capital improvements, minus depreciation already taken. An owner who started a company from scratch with no cash investment has roughly zero basis, so almost the entire sale price is taxable gain. An owner who bought the business for $3M and sells for $8M has $5M of gain. Depreciation taken over the holding period reduces basis dollar for dollar and gets recaptured at ordinary rates on sale.

When do I have to pay the tax on a business sale?

For an all-cash deal closing in 2026, the tax is due with your 2026 federal return by April 15, 2027, with quarterly estimated payments potentially required in Q3 and Q4 of 2026 to avoid underpayment penalties. For an installment sale under Section 453, you pay tax pro-rata as you receive payments over multiple years. For an earnout, the tax timing follows the payment timing under installment rules, though imputed interest under Section 483 can complicate the allocation.

Does it matter if my company is an LLC, S-corp, or C-corp when I sell?

Yes, more than almost any other variable. LLCs taxed as partnerships and S-corps are pass-throughs with single-layer tax. C-corps face double tax in an asset sale unless QSBS applies. The entity choice you made at formation can cost or save 15 to 25 percentage points of your sale proceeds. Conversion from C-corp to S-corp triggers a 5-year built-in gains tax window under Section 1374, so the planning has to start years before the sale.

What to Do Next

The single highest-return hour you can spend before selling a company is with a transaction-experienced CPA or tax attorney reviewing your entity type, basis, state of residence, and likely deal structure. If you are 12 to 36 months from an exit, that conversation can change your net by 7 figures. If you are 30 days from signing an LOI, your options are narrower but still worth modeling.
