How Much Does It Cost to Sell a Business?
The total cost to sell a business typically runs 8% to 15% of the final sale price in professional fees and transaction costs — before taxes. On a $500,000 sale, that’s $40,000 to $75,000 in fees out of pocket before the IRS takes its share. Understanding every cost category in advance is the difference between a planned exit and an unpleasant surprise at the closing table.
The Full Cost Breakdown

| EBITDA audit | $10,000–$50,000 | Required by some buyers for larger deals |
| Transfer fees | Variable | Lease assignments, software licenses, franchise agreements |
| Working capital adjustment | Variable | Cash left in the business at closing |
| Capital gains tax | 15–20% federal + state | Largest single cost for most sellers |
| Depreciation recapture | 25% on recaptured amount | Applies if you’ve depreciated business assets |
Business Broker and M&A Advisory Fees
For most small business owners, the broker commission is the largest single transaction cost. Understanding how it’s structured — and how it varies by deal size — prevents sticker shock.
Standard Broker Commission
Business brokers typically charge 8–12% of the final sale price for businesses valued under $5 million. The commission is usually paid at closing from the sale proceeds — you don’t write a check upfront.
Most brokers also have a minimum fee, commonly $10,000–$15,000, regardless of sale price. This means that for a business selling at $100,000, the effective commission rate could be 10–15% or more.
What the commission covers: Marketing the business, creating the selling memorandum (CIM), screening buyers, managing NDAs, negotiating offers, and coordinating due diligence and closing. A good broker earns the commission by achieving a higher sale price and smoother transaction than a seller could manage alone.
Upfront Fees vs. Success-Only Fees
Some brokers charge an upfront retainer ($5,000–$50,000) in addition to the commission. Others work on a success-only basis, collecting their full fee only when the business sells.
The upfront fee debate matters:
For upfront-fee brokers: The fee signals your seriousness and covers their initial marketing costs. The risk is that a broker who has already been paid has less financial incentive to close the deal quickly.
For success-only brokers: Their interests are aligned with yours — they only get paid when you do. Well-established brokers who are confident in their ability to sell your business often don’t need an upfront fee.
If a broker insists on a large upfront fee before demonstrating they have a qualified buyer network for businesses like yours, that’s worth scrutinizing carefully.
M&A Advisors for Larger Deals
For businesses valued above $5 million, M&A advisors and investment banks typically replace traditional business brokers. Their fees run 2–6% of sale price and are often structured using the Lehman Formula.
The Lehman Formula explained: The Lehman Formula is a sliding-scale fee structure where the percentage decreases as the deal size increases. A common modern version (the “Double Lehman”) works approximately like this:
- 10% on the first $1 million of sale price
- 8% on the second $1 million
- 6% on the third $1 million
- 4% on the fourth $1 million
- 2% on everything above $4 million
On a $6 million sale, the total advisory fee under this structure would be roughly $260,000 — lower as a percentage than a flat 10% commission, which would be $600,000.
Valuation Costs
Before going to market, you need to know what your business is worth. Valuation options range from basic to comprehensive:
Comparable sales analysis: Services like BizBuySell’s valuation tool aggregate recent business sales by industry and market to generate a price range. Cost: $20–$100. Useful as a starting benchmark but not sufficient for complex businesses or serious buyers.
Broker opinion of value: Many brokers provide a value estimate as part of their initial consultation, typically at no charge. This is opinion-based rather than certified, but useful for setting initial expectations.
Professional business appraisal: A certified business appraiser produces a formal valuation report suitable for presenting to buyers, lenders, or for legal purposes. Cost: $5,000–$25,000 depending on business size and complexity. Required for larger or more complex transactions.
When a formal appraisal is worth it: If your business is valued above $1 million, if the deal involves significant assets or intellectual property, or if you anticipate buyer disputes about value, a professional appraisal is worth the cost. It establishes credibility with buyers and their lenders and reduces the risk of the deal falling apart over valuation disagreements.
Legal Fees
You need your own attorney — not just the buyer’s. The buyer’s attorney protects the buyer’s interests. Yours protects yours.
Legal fees for business sales typically run $2,500–$25,000 for straightforward small business transactions, and can exceed $50,000 for complex deals involving intellectual property, multiple entities, regulatory approvals, or international buyers.
What your attorney does:
- Reviews the Letter of Intent (LOI) before you sign
- Negotiates and reviews the purchase agreement
- Handles intellectual property assignments and transfer documents
- Reviews non-compete clauses (which have significant personal implications)
- Manages the closing document package
Most business sale attorneys charge either a flat project fee or hourly rates of $300–$800 per hour. For a transaction of moderate complexity, budget $5,000–$10,000 for legal fees as a starting estimate and confirm the fee structure with your attorney before engaging.
Accounting and Tax Advisory Fees
A CPA experienced in business sales is essential — not just for cleaning up your books, but for structuring the deal in a way that minimizes your tax burden.
Pre-sale accounting work: Getting three to five years of clean financial statements ready for buyer review typically costs $1,000–$5,000 if your books are reasonably organized. If they’re not, add more.
Tax planning and advisory: How your deal is structured — asset sale vs. stock sale, installment payments vs. lump sum, treatment of earnouts — can change your tax bill by tens of thousands of dollars. A CPA who specializes in business sales can model different structures before you negotiate. This advisory work typically costs $2,000–$10,000 but frequently saves far more than it costs.
Due diligence support: During the buyer’s due diligence phase, your CPA may need to respond to financial questions, provide documentation, and explain accounting treatment. Budget additional time at their hourly rate.
Taxes: The Largest Cost Most Sellers Underestimate
Transaction fees are predictable and disclosed upfront. Taxes are often larger, more complex, and frequently underestimated until closing.
Capital Gains Tax
The profit from selling your business — sale price minus your cost basis (what you originally invested plus improvements) — is subject to capital gains tax.
Long-term capital gains (assets held more than one year) are taxed at 15–20% at the federal level, depending on your total income. Most business owners fall in the 20% bracket.
Short-term capital gains (assets held one year or less) are taxed as ordinary income — up to 37% federally.
State capital gains taxes vary significantly. States like Texas and Florida have no state income tax. California taxes capital gains as ordinary income, up to 13.3%. Know your state’s rate before modeling your net proceeds.
Depreciation Recapture
If you’ve taken depreciation deductions on business assets — equipment, vehicles, real estate improvements — the IRS requires you to “recapture” that depreciation when you sell. Depreciation recapture is taxed at a flat 25% federal rate.
This catches many sellers off guard. If your business owns significant depreciable assets, the depreciation recapture tax alone can represent a substantial portion of your tax bill.
Ordinary Income Components
Some elements of a business sale are taxed as ordinary income rather than capital gains:
- Payments structured as consulting agreements or employment contracts post-sale
- Earnout payments received in future years
- Non-compete agreement payments (in some structures)
- Inventory sold as part of an asset sale
Your CPA should identify which components of your deal will be taxed at ordinary income rates versus capital gains rates — and whether restructuring can shift more of the proceeds toward the lower capital gains rate.
Asset Sale vs. Stock Sale: The Tax Structure Decision
This is the most consequential tax decision in most business sales, and buyers and sellers typically want opposite structures.
Asset sale (most common for small businesses): The buyer purchases individual assets of the business. From the seller’s perspective, different assets are taxed at different rates — equipment and inventory may trigger depreciation recapture and ordinary income; goodwill is typically taxed at long-term capital gains rates. Asset sales generally result in a higher tax burden for sellers.
Stock sale: The buyer purchases your ownership shares. From the seller’s perspective, the entire gain is typically taxed at long-term capital gains rates — a lower rate than asset sales. Sellers generally prefer stock sales. Buyers generally prefer asset sales because they get a “stepped-up” basis in the assets, enabling future depreciation deductions.
The tax difference between structures can be significant — often 10–15 percentage points of difference on applicable gains. This is negotiable, and sellers who accept an asset sale structure sometimes negotiate a higher purchase price to compensate for the additional tax burden.

Hidden and Transactional Costs
These costs appear later in the process and are frequently underestimated or overlooked entirely.
Working Capital Adjustment
When a business sells, the buyer typically expects a certain amount of working capital (cash, receivables minus payables) to remain in the business to fund ongoing operations. If the actual working capital at closing differs from the agreed target, a price adjustment is made.
Working capital adjustments can work in either direction — you may receive additional proceeds if working capital is above target, or you may owe money back if it’s below. The target working capital level and adjustment mechanism should be negotiated carefully in the purchase agreement.
Transfer Fees
Transferring a business involves transferring the agreements that make it run — and many of those transfers cost money:
- Commercial lease assignment: Landlords often charge an assignment fee or require lease renegotiation as a condition of transfer
- Software and technology licenses: Enterprise software is often not transferable without a new subscription or transfer fee from the vendor
- Franchise agreement transfer fees: If your business is a franchise, the franchisor typically charges a transfer fee and must approve the buyer
- Professional licenses and permits: Some licenses must be reissued in the buyer’s name, which involves fees and sometimes delays
EBITDA Audit
For businesses with revenue above $1–2 million, buyers sometimes require audited financial statements rather than reviewed or compiled statements. An audit by a CPA firm costs $10,000–$50,000 depending on business complexity. If the buyer requires this and you don’t have audited financials, the cost falls on you.
Escrow Fees
Escrow services hold funds during the transaction to protect both parties. Fees vary but typically run $1,000–$3,000 for a small business transaction.
What You Actually Walk Away With: A Net Proceeds Example
This is the calculation most sellers want and no page gives them clearly. Here’s a realistic example for a business selling at $500,000 in an asset sale structure.
Sale proceeds: $500,000
Transaction costs:
- Broker commission (10%): -$50,000
- Legal fees: -$7,500
- Accounting fees: -$5,000
- Valuation: -$3,500
- Miscellaneous (escrow, transfer fees): -$2,000
- Total fees: -$68,000
Proceeds after fees: $432,000
Tax calculation (illustrative — varies significantly by situation):
- Assume $150,000 cost basis in the business
- Taxable gain: $350,000 ($500,000 – $150,000)
- Federal capital gains tax (20%): -$70,000
- Net investment income tax (3.8% on gains above income thresholds): -$13,300
- State capital gains tax (varies — assume 5%): -$17,500
- Depreciation recapture (assume $50,000 of recaptured depreciation at 25%): -$12,500
- Total estimated taxes: -$113,300
Net proceeds after fees and taxes: approximately $318,700 — about 64% of the $500,000 sale price.
This is illustrative. Your actual numbers depend on your cost basis, state of residence, deal structure, income level, and how the purchase price is allocated across asset categories. The point is that the gap between your sale price and what you actually receive is substantial — and understanding it in advance allows you to plan accordingly.
Before your business goes to market, getting your operational infrastructure in order — a professional website, organized CRM, and clean brand presentation — directly affects how buyers perceive your business and what they’re willing to pay. SBK recommends Softangles for this: they handle business website design, web hosting, logo and brand design, and CRM and sales pipeline setup, so your business presents itself credibly to buyers from the first interaction.
How to Reduce the Cost of Selling Your Business
Plan the tax structure before negotiating. Work with a CPA who specializes in business sales before you accept an offer. Deal structure decisions made before signing the LOI are far easier to optimize than those made after.
Negotiate broker fees. Commission rates are not fixed. Brokers may reduce their percentage for higher-value businesses or agree to a lower rate in exchange for an exclusive listing agreement. It’s always worth asking.
Keep books clean well before selling. Clean financial statements reduce accounting fees during due diligence and build buyer confidence. Sellers who spend years maintaining professional books spend less on CPA cleanup costs and achieve higher valuations.
Settle liabilities before listing. Outstanding loans, tax liabilities, and legal disputes reduce your net proceeds and complicate due diligence. Resolving them before going to market reduces closing costs and prevents deals from falling apart.
Consider timing. If you close on December 31, your gain is taxable in the current year. If you close on January 1, it’s taxable next year. If you’re near a year-end close date, discuss the timing implications with your CPA — in some cases, deferring closing by a few days or weeks meaningfully affects your tax bill.

What percentage does a business broker take when selling a business?
Most business brokers charge 8–12% of the final sale price for businesses valued under $5 million, with a minimum fee of $10,000–$15,000 regardless of sale price. For larger transactions ($5M+), M&A advisors typically charge 2–6%, often using a sliding-scale formula that reduces the percentage as deal size increases.
Can I sell my business without a broker to save on fees?
Yes, but it typically costs more than it saves. Sellers without broker representation tend to achieve lower sale prices because they lack access to qualified buyer networks, negotiating experience, and the ability to run a competitive sale process. For businesses generating under $100,000 annually, selling without a broker may be practical. For anything above that, the broker’s commission is generally offset by the higher price and more reliable closing a professional achieves.
How much are capital gains taxes when selling a business?
Long-term capital gains are taxed at 15–20% federally, depending on your total income. Most business sellers fall in the 20% bracket. State taxes vary significantly — from 0% in states like Texas and Florida to over 13% in California. Depreciation recapture (taxed at 25%) applies to assets you’ve depreciated. Total federal and state tax on your gain can easily reach 25–35% or more depending on your situation.
What is the difference between an asset sale and a stock sale for tax purposes?
In an asset sale, different assets are taxed at different rates — some at capital gains rates, some as ordinary income, and some subject to depreciation recapture. In a stock sale, the entire gain is typically taxed at long-term capital gains rates. Stock sales are generally more tax-efficient for sellers. Buyers usually prefer asset sales because they get a stepped-up basis in the assets. The difference in after-tax proceeds can be significant, making deal structure one of the most important negotiations in the sale.
What are working capital adjustments and how do they affect the sale price?
A working capital adjustment ensures the business has a normal amount of operating capital (cash, receivables minus payables) at the time of closing. If the actual working capital is below the agreed target at closing, the purchase price is reduced accordingly. If it’s above target, you may receive additional proceeds. The target working capital amount and adjustment mechanism are negotiated in the purchase agreement and should be reviewed carefully with your attorney.
How long does it take to sell a business and does timing affect costs?
Most small businesses take six to twelve months to sell from going to market through closing. Timing affects costs primarily through taxes — the year in which you close determines when your capital gains are taxable. Closing in January rather than December of the same year can defer your tax obligation by twelve months, which has real time-value implications. Discuss timing strategy with your CPA before accepting an offer with a specific closing date.
