Exiting or Selling Your Business in the United States
2026 Tax, Valuation & Succession Planning Guide

Overview

Exiting or selling a business requires careful planning to minimize taxes, maximize value, and ensure a smooth transition. This guide explains the key tax rules, valuation considerations, and compliance requirements that apply when U.S. business owners sell, transfer, or wind down their business.

Readers will learn how different exit structures affect taxation, what documents are required, and how to prepare for due diligence under 2026 regulations. The focus is on practical, regulation-based strategies for U.S. taxpayers — with specific attention to OBBBA changes that took effect for the 2026 tax year.

Why This Matters

Business exits trigger significant tax consequences — capital gains, depreciation recapture, and potential double taxation for C-Corporations — that can substantially reduce after-tax proceeds. Poor planning can result in higher taxes, buyer disputes, or failed transactions.

Types of Business Exits

The choice of exit structure determines how gains are taxed, what liabilities transfer, and how the transaction is reported. Sellers and buyers typically have opposing preferences — sellers prefer stock sales; buyers prefer asset purchases.

2026 Tax Rates — Gains & Recapture

Business sale proceeds are subject to different rates depending on the nature of each component of the gain. Understanding the applicable rate for each asset class is essential for pre-sale tax modeling.

Long-Term Capital Gains — 2026 (Single Filer)

Depreciation Recapture — §1245 vs. §1250

Key Rules & Concepts

A. Purchase Price Allocation — Form 8594

• In an asset sale, both buyer and seller must file Form 8594(Asset Acquisition Statement) reporting the agreed allocation of purchase price across seven asset classes: cash, marketable securities, accounts receivable, inventory, other assets, Section 197 intangibles, and goodwill.
• The allocation directly determines the seller's tax rate on each component — goodwill is generally taxed at long-term capital gains rates; equipment triggers §1245 recapture at ordinary rates; inventory is ordinary income.
• Buyer and seller allocations must be consistent. IRS cross-references both returns — mismatches trigger inquiries. Negotiating the allocation is as important as negotiating the purchase price.
• Misallocating purchase price — for example, attributing excess value to assets that generate ordinary income rather than goodwill — does not reduce tax; it creates inconsistency and audit risk.

B. Installment Sales — IRC §453

• An installment sale allows the seller to spread gain recognition over the payment period rather than recognizing the full gain in the year of sale. Each payment received includes a proportionate return of basis, capital gain, and potentially ordinary income.
• Installment reporting is not available for depreciation recapture — §1245 and §1250 recapture must be recognized in full in the year of sale, regardless of when payments are received.
• Installment sales create credit risk — if the buyer defaults, the seller may need to repossess and re-recognize gain. A security interest in the sold assets should be documented in the purchase agreement.
• The seller may elect out of installment reporting (and report all gain in the year of sale) if the full upfront tax cost is preferable, for example, to lock in current lower rates.

C. C-Corp Double Taxation in Asset Sales

• When a C-Corporation sells assets, gain is taxed at the corporate level(21% flat federal rate). When the after-tax proceeds are distributed to shareholders as a dividend or liquidating distribution, they are taxed again at the shareholder level at qualified dividend rates (0%, 15%, or 20% + 3.8% NIIT).
• This double taxation makes asset sales of C-Corps significantly more expensive than stock sales. Buyers prefer asset purchases (for the step-up in basis); sellers prefer stock sales (single capital gain). This tension is typically resolved through purchase price negotiation.
• IRC §338(h)(10) election allows certain C-Corp stock sales to be treated as asset sales for tax purposes — the buyer gets an asset step-up; the seller pays tax as if it were an asset sale. Used when buyer's need for basis step-up outweighs seller's preference.

D. S-Corp Built-In Gains Tax — IRC §1374

• If a C-Corporation converted to S-Corporation status and sells assets within 5 years of the conversion, the built-in gain (appreciation that existed at the time of conversion) is subject to corporate-level tax at the 21% rate — even though the entity is now an S-Corp.
• After the 5-year recognition period has passed, the built-in gains tax no longer applies and gains flow through to shareholders at individual capital gains rates.

E. Valuation Considerations

• EBITDA multiples are the most common valuation benchmark for operating businesses. Industry multiples vary widely — a professional services firm may trade at 3–5x EBITDA; a SaaS business may trade at 8–15x or more.
• Normalization adjustments add back personal expenses charged through the business, one-time costs, and above- or below-market owner compensation to arrive at true economic EBITDA.
• Discounted Cash Flow (DCF) is used for businesses with predictable, long-term revenue streams. More complex and sensitive to discount rate assumptions.
• Removing personal expenses from the books before a sale increases valuation — each dollar of expenses removed at a 5x multiple increases enterprise value by $5.

F. Due Diligence Requirements

• Buyers typically request 3–5 years of business and personal tax returns, GAAP-compliant financial statements, payroll records, sales tax compliance history, all contracts and leases, corporate governance documents, and insurance certificates.
• Outstanding IRS tax liens, payroll tax delinquencies, or unresolved state tax issues will surface in due diligence and typically result in purchase price adjustments or escrow holdbacks.
• Businesses with clean, well-organized records close faster and at better valuations. Due diligence delays are among the most common causes of failed transactions.

QSBS — Section 1202 Qualified Small Business Stock (OBBBA)

Section 1202 of the Internal Revenue Code allows noncorporate taxpayers(individuals, trusts, and estates) to exclude a portion or all of the capital gain on the sale of qualified small business stock (QSBS). The OBBBA made significant changes effective for stock issued after July 4, 2025.

2026 QSBS Eligibility Requirements

• Stock must be in a domestic C-Corporation. S-Corporations, LLCs, and partnerships do not qualify. LLCs that have elected C-Corp treatment may qualify.
• The corporation's aggregate gross assets must not have exceeded $75 million(raised from $50M under OBBBA; inflation-adjusted from 2027) at any time from incorporation through the date of stock issuance.
• The maximum gain exclusion per taxpayer per issuing company is the greater of $15 million(raised from $10M under OBBBA; inflation-adjusted) or 10 times the taxpayer's adjusted basis in the stock.
• Stock must have been acquired at original issuance in exchange for money, property, or services — not in a secondary market purchase.
• The corporation must be engaged in a qualified trade or business. Excluded industries include: health, law, engineering, accounting, consulting, financial services, hospitality, banking, and insurance. Technology, manufacturing, and most other sectors qualify.

Step-by-Step Guidance

Practical Examples

Common Mistakes

• 1 Not planning the exit at least 1–2 years in advance. Tax strategies such as installment sales, income shifting, retirement plan contributions, and QSBS structuring require time. Decisions made at the closing table cannot undo years of suboptimal structure.
• 2 Mixing personal and business expenses, lowering valuation. Personal expenses run through the business reduce reported EBITDA — the primary basis for business valuation. Normalizing these adjustments during due diligence is seller-unfavorable; removing them before marketing the business maximizes valuation multiples.
• 3 Incorrect purchase price allocation on Form 8594. Seller and buyer must file consistent allocations. Mismatches are flagged by IRS matching; aggressive allocations to tax-favored asset classes without economic justification are audit targets.
• 4 Failing to track adjusted basis before the sale. The seller's basis determines the taxable gain. Owners who have never maintained a basis schedule — particularly S-Corp shareholders whose basis fluctuates with annual K-1 allocations — frequently miscalculate their gain and the resulting tax.
• 5 Not understanding depreciation recapture. Sellers who claimed §179 or 100% bonus depreciation are surprised to find that the same assets generating large prior-year deductions now produce large ordinary income inclusions at sale. Pre-sale modeling must include recapture estimates for every depreciated asset.
• 6 Poor documentation leading to buyer distrust and deal failure. Disorganized financial records, missing contracts, and unresolved compliance issues discovered in due diligence erode buyer confidence, reduce purchase price, or kill transactions outright.
• 7 Ignoring payroll and sales tax liabilities before closing. Unpaid payroll taxes and sales tax liabilities survive entity sales in many structures and create personal liability for the seller under trust fund recovery penalties (IRC §6672). These must be resolved before — not after — closing.
• 8 Not filing final returns or dissolution documents. Stopping operations without formally dissolving the entity leaves it legally alive — subject to ongoing franchise taxes, annual report fees, and potential IRS notices for non-filing. Every state where the business was registered requires a separate dissolution filing.
