Accounting guidance for business acquisitions, goodwill, purchase price allocation, and deal structuring
ASC 350 lets private companies amortize goodwill over up to ten years and test for impairment only when a triggering event occurs. This guide walks through ASU 2014-02 and 2021-03 elections, the single-step Step One quantitative test after ASU 2017-04, and how to keep auditors and lenders aligned.
Section 280G disallows the corporate deduction and imposes a 20% Section 4999 excise tax once parachute payments to a disqualified individual reach three times the executive's five-year average W-2 compensation, with the penalty applying to everything above 1× the base amount. Private companies can eliminate the consequences entirely through a 75% disinterested shareholder vote paired with conditional waivers signed before closing.
Customer concentration above 10% triggers GAAP disclosure, and concentrations above 30% can knock 20–35% off a sale price and shrink bank advance rates. Where the danger thresholds sit, how lenders and acquirers price the risk, and how to diversify revenue before it costs you.
About one third of 2024 private-target M&A deals included an earnout, and median earnout potential rose to roughly 43% of the closing payment. This guide explains contingent purchase price structure, Section 453 installment-sale tax mechanics, the compensation-versus-purchase-price trap, and the recurring drafting mistakes behind six of the last seven major Delaware decisions favoring sellers.
Buyers and sellers in an asset acquisition must each file Form 8594 under Section 1060, allocating consideration across seven asset classes using the residual method.

Section 197 lets buyers in U.S. asset acquisitions amortize goodwill, customer lists, non-competes, and other intangibles ratably over 180 months. This guide covers the eight qualifying categories, Form 8594 allocation across Classes I–VII, the pooling rule, and anti-churning traps that can wipe out the deduction.
Three valuation approaches — asset, income, and market — can produce 50% differences in indicated value for the same closely-held business. This guide explains when each fits, how DLOM and DLOC discounts apply, and what records owners need before a sale, partner buyout, or estate transfer.
How IRC Section 453 and Form 6252 let sellers spread capital gain on seller-financed real estate or business sales across the years payments arrive — including the gross profit percentage formula, the depreciation recapture trap, the Section 453A interest charge on installment balances above $5 million, and when to elect out.
An asset sale vs stock sale changes who pays tax, who carries liability, and how a deal closes. Compare 2026 tax math, successor liability doctrines, and the S-corp hybrid structures — Section 338(h)(10) and F-reorganizations — that now dominate mid-market deals.
