M&A Tax Strategy: How Deal Structure Determines Your After-Tax Proceeds

A joint tax election that lets a stock sale be treated as an asset sale for federal tax purposes, giving the buyer a stepped-up tax basis in the company's assets while the seller recognizes gain as if assets were sold.

The tax treatment of gain from selling a capital asset (like a business). Long-term capital gains (asset held >1 year) are taxed at preferential federal rates (typically 20%); short-term gains and ordinary income can be taxed at up to 37%.

When depreciable assets (equipment, buildings) are sold in an asset sale above their depreciated book value, the IRS "recaptures" prior depreciation deductions — taxing the gain up to the original depreciation taken at ordinary income rates (up to 37% federal) rather than capital gains rates. For sellers, depreciation recapture is one of the biggest tax disadvantages of asset sales vs. stock sales. Recapture can represent $100K-$1M+ of additional tax on a typical SMB asset sale with equipment-heavy assets.

A tax-free reorganization under IRC Section 368(a)(1)(F) that restructures an S-corporation into a new holding company — often used to give buyers a stepped-up tax basis while preserving stock-sale treatment for the seller.

Gross-up is a tax concept relevant to M&A transaction structuring — how it applies affects a seller's after-tax proceeds and a buyer's cost basis.

A sale where the seller receives payments over multiple years and — if elected — recognizes the taxable gain ratably as payments are received rather than all in the year of sale. Available for seller notes and earnouts in most circumstances.

A tax attribute created when a business's allowable deductions exceed gross income for a tax year — usable to offset future taxable income and reduce tax liability. In M&A, acquired NOLs are subject to Section 382 limitations: when ownership changes by more than 50% over a 3-year period (which nearly every M&A transaction triggers), the amount of NOL usable annually is capped at the Section 382 limitation (essentially equity value × long-term tax-exempt rate). Large NOLs may have limited practical value post-acquisition due to these caps.

The allocation of total purchase price across asset categories (inventory, equipment, real estate, goodwill, etc.) for tax purposes under IRC Section 1060 — affecting seller's tax treatment and buyer's future depreciation deductions.

Qualified Small Business Stock under IRC Section 1202 — a tax provision providing up to 100% federal capital gains exclusion (capped at $10M or 10x basis) on gains from qualifying C-corp stock held more than 5 years.

A federal tax exclusion under IRC Section 1202 allowing eligible shareholders to exclude up to $10 million (or 10x invested basis) of capital gains from federal taxation on the sale of qualified small business stock held for more than five years.

Section 336(e) Election is a tax concept relevant to M&A transaction structuring — how it applies affects a seller's after-tax proceeds and a buyer's cost basis.

The tax benefit created by deductible expenses — primarily interest on debt — that reduces taxable income and increases after-tax cash flow. In LBO structures, interest on acquisition debt creates a tax shield that reduces effective debt cost: a 10% interest rate on debt with a 25% tax rate has an effective after-tax cost of 7.5%. The interest tax shield is a core driver of LBO return mechanics — leverage enhances returns both through capital structure amplification and tax-reduced debt service cost.

Write-off is a tax concept relevant to M&A transaction structuring — how it applies affects a seller's after-tax proceeds and a buyer's cost basis.
