Taxes When You Sell Your Business: A 2026 Owner's Guide

How much tax will I pay when I sell my business?

Most business sellers pay an effective tax rate of roughly 20% to 30% on their gain. The largest piece is the federal long-term capital gains rate of 15% to 20%, plus the 3.8% net investment income tax (NIIT) for high earners, plus state income tax of 0% to 13.3%. Portions of the price treated as ordinary income — depreciation recapture and inventory — can be taxed as high as 37% federally.

Your gain is the sale price minus your tax basis (roughly what you paid plus improvements, minus depreciation already deducted). A dentist selling a practice for $3M that she started from nothing has a far larger taxable gain than a manufacturer who bought equipment for $3M last year. Two levers move your number the most: the sale structure (asset vs. stock) and the purchase price allocation across asset types.

To estimate the gross proceeds you are starting from, model your value first — most small businesses sell for 2-4x SDE or 4-8x EBITDA. Our business valuation calculator gives you a quick estimate before you layer in tax.

Asset sale vs. stock sale: which is better for taxes?

For the seller, a stock sale is almost always better: nearly the entire gain is taxed at the 15-20% long-term capital gains rate. Buyers prefer asset sales because they get a stepped-up basis to re-depreciate and can leave most liabilities behind — but asset sales push more of your gain into higher-taxed ordinary income. The structure is one of the most heavily negotiated points in any deal, and it directly trades buyer benefit against seller tax.

The reason this matters most for C-corporations is double taxation: in a C-corp asset sale, the corporation pays tax on the gain, and then shareholders pay again when proceeds are distributed. That is why C-corp owners — and many veterinary, manufacturing, and MSP/IT founders who incorporated decades ago — fight hard for a stock sale. Pass-through entities (S-corps, LLCs, partnerships) are taxed once at the owner level either way, but still feel the asset-sale recapture hit.

Because the structure favors opposite sides, it is often a negotiation lever: buyers may pay a higher price for an asset deal to offset your extra tax, or a seller may accept a stock deal at a lower price knowing the after-tax result is better. A Section 338(h)(10) or 336(e) election can sometimes give a buyer asset-sale tax treatment on what is legally a stock sale — your CPA should model this.

What capital gains tax rate applies when I sell?

If you have owned the business more than one year, your gain is long-term capital gain, taxed federally at 0%, 15%, or 20% depending on your taxable income. Most sellers of meaningful businesses land in the 15-20% bracket. On top of that, high earners pay the 3.8% NIIT on investment income once modified adjusted gross income exceeds roughly $200,000 (single) or $250,000 (married filing jointly).

So a top-bracket seller faces a combined federal capital gains rate near 23.8% before state tax. Note, though, that the 3.8% NIIT generally does not apply to gain from a business in which you materially participate (IRC §1411), so many owner-operators land nearer 20% federal — the NIIT mainly hits C-corp stock and passive owners. A large one-year gain often pushes you into the top bracket for that year alone, even if your normal income is modest — which is exactly why spreading the gain (see installment sales below) can help. The full chain looks like this:

Compare that to selling through a broker, where commissions of 8-12% come straight off the top before tax. Working with an off-market platform like DealSeam — which is free to sellers because buyers pay the success fee — keeps more of the headline price in the base you control.

What is purchase price allocation and why does it matter?

Purchase price allocation is how you and the buyer split the total price across asset classes in an asset sale — and it directly determines your tax bill, because each class is taxed differently. In an asset deal both sides must report a matching allocation to the IRS on Form 8594 under Section 1060. Where the dollars land is negotiable, and buyer and seller incentives are opposite.

You generally want more of the price allocated to goodwill (taxed at the favorable 15-20% capital gains rate). The buyer often wants more allocated to equipment and inventory they can deduct or re-depreciate quickly. Here is how the common buckets are taxed to the seller:

Example: a CPA firm sells for $2M in an asset deal. Allocating $1.7M to goodwill and $300K to equipment and a non-compete produces a very different result than a 50/50 split. Allocation is one of the highest-leverage, lowest-effort ways to cut your tax — negotiate it explicitly, and never sign a deal that leaves the Form 8594 split to the buyer.

What is depreciation recapture and how is it taxed?

Depreciation recapture is the part of your gain that comes from depreciation you already deducted — and the IRS claws it back at ordinary income rates instead of capital gains rates. For equipment and personal property (Section 1245), recapture is taxed as ordinary income up to 37%. For real estate (unrecaptured Section 1250 gain), the depreciation portion is taxed at a maximum federal rate of 25%.

This is the hidden cost of an asset sale. A trucking company that wrote off its fleet with bonus depreciation, or an HVAC business that expensed its vans and equipment, can have a large recapture bill — those deductions saved tax in prior years, and now part of the sale gets taxed at ordinary rates rather than the 15-20% capital gains rate.

Recapture is also why an installment sale only helps so much: as noted below, the recapture must be reported in full in the year of sale, even if you collect the cash over several years.

How are ordinary income and capital gains portions taxed?

A business sale almost always produces both kinds of income, and the split is the single biggest driver of your effective rate. Long-term capital gain (goodwill, most of the entity value) is taxed at 15-20%. Ordinary income (depreciation recapture, inventory, consulting payments, and most earnouts tied to your services) is taxed at your marginal rate, up to 37% federally — more than double the capital gains rate.

The practical takeaway: every dollar you can legitimately move from the ordinary bucket to the capital gains bucket is worth roughly 15-20 cents in after-tax savings. That is the entire game behind allocation, structure, and how a non-compete or consulting agreement is written. A veterinary practice owner who lets $300K get labeled "consulting" rather than goodwill is volunteering ordinary-income tax on money that could have been capital gain.

Can an installment sale or seller note spread the gain?

Yes. Under IRS Section 453, an installment sale or seller note lets you recognize capital gain as you receive payments rather than all in one year. Spreading the gain can keep you in the 15% capital gains bracket longer, keep some years under the 3.8% NIIT threshold, and smooth your state tax. Seller notes are common in lower-middle-market deals where the buyer finances part of the price over 2-5 years.

The catch every owner forgets: depreciation recapture is not eligible for installment deferral. You must report all Section 1245 recapture in the year of sale, even though you have not collected the cash for it — so an equipment-heavy seller can owe ordinary-income tax up front on money still owed to them. You also charge (and are taxed on) interest on the deferred balance, and you take on the credit risk that the buyer pays.

What is QSBS (Section 1202) and can it eliminate my tax?

Qualified Small Business Stock (QSBS) under Section 1202 is one of the most powerful breaks in the tax code: it can let you exclude a large share of your gain — often up to 100% — from federal tax. The traditional exclusion is the greater of $10 million or 10x your basis per company. But it comes with strict requirements that most Main Street businesses do not meet.

To qualify under the classic rules, the stock generally must be:

• C-corporation stock (not S-corp, LLC, partnership, or sole proprietorship)
• Acquired at original issuance, directly from the company
• Held more than five years
• In a company with gross assets at or under $50 million when the stock was issued
• In a qualified trade or business (most professional-service and finance businesses are excluded)

Legislation enacted in 2025 introduced a tiered exclusion (a partial exclusion at three and four years) and raised the per-issuer cap and gross-asset threshold for stock issued after July 4, 2025. Because these thresholds are new and being interpreted, confirm the current QSBS rules with a tax advisor before relying on them. QSBS is most relevant to founders of vertical-SaaS and other C-corp tech companies — not the typical dental, HVAC, or trucking seller operating as an S-corp or LLC.

How are earnouts taxed when I sell my business?

Earnouts — contingent payments based on the business hitting future targets — are generally taxed as you receive them. If the earnout is part of the purchase price for your business (a capital asset), it usually keeps capital gains treatment under the contingent-payment installment rules, with a portion of each payment treated as taxable interest. Earnouts can be a meaningful share of deal value, especially in PE transactions.

The danger is recharacterization. If the earnout is conditioned on you continuing to work for the buyer, the IRS can treat it as ordinary compensation — taxed up to 37% plus payroll taxes — rather than capital gain. A dental-group owner who accepts an earnout that vanishes if she leaves may have effectively signed up for W-2 income, not a higher sale price. Keep the earnout tied to business performance, not your employment, and have counsel draft it carefully.

How much does state tax vary when I sell?

State tax on a business sale ranges from 0% to about 13.3% of the gain. Nine states have no income tax — including Florida, Texas, Wyoming, Nevada, and Tennessee — so a seller there owes no state tax on the gain (note: Washington taxes long-term capital gains above ~$270K at 7%). At the other extreme, California taxes capital gains as ordinary income at up to 13.3%, which can add six figures to a meaningful exit.

Do not assume you can simply move to dodge it. Many states use source-based rules, taxing the portion of gain attributable to a business that operated in that state regardless of where you now live, and some apply residency look-back tests. A manufacturer relocating from California to Texas the month before closing may still owe California tax on much of the gain. State planning needs a head start of months, not weeks.

How can I structure the deal to keep more after-tax?

The highest-impact tax planning happens before the letter of intent, while structure is still negotiable. Once terms are signed, most of your levers are gone. These are the moves owners use most often — each should be vetted by your CPA against your specific facts:

• Negotiate structure deliberately — push for a stock sale (or 338(h)(10) election) when you own a C-corp to avoid double taxation.
• Control the purchase price allocation in writing and weight it toward goodwill (capital gain) over equipment and consulting (ordinary income).
• Use an installment sale or seller note to spread goodwill gain across years and stay under bracket and NIIT thresholds.
• Keep earnouts tied to business performance, not your continued employment, to preserve capital gains treatment.
• Check QSBS eligibility early if you own qualifying C-corp stock held over five years.
• Plan state residency and source rules months ahead — do not assume a last-minute move avoids state tax.
• Consider charitable or trust strategies (e.g., a charitable remainder trust or gifting appreciated equity) for very large gains.
• Time the closing — pushing a sale into a year with lower other income can keep more gain in the 15% bracket.
