Asset vs. Stock Purchase: The Foundational Tax Decision Explained

An asset purchase gives you fresh depreciation and stepped-up basis; a stock purchase means inheriting the seller's tax history and existing asset basis. The difference in lifetime tax cost is often six figures and should be understood before signing any agreement.

Asset purchase means buying individual items. You acquire the equipment, inventory, customer lists, and goodwill separately. You get a fresh cost basis on everything, which means new depreciation and amortization deductions. You generally do not inherit the seller's liabilities.

Stock purchase means buying the entity itself. You acquire the company's ownership shares or membership units. The business continues with its existing tax history, depreciation schedules, and potential liabilities intact. Your depreciation deductions are limited to what remains on the entity's books.

The tax gap between these two structures is often six figures. A CPA runs projections for both and shows you the after-tax cost difference in plain numbers before you commit.

The pitfall: Many buyers sign a letter of intent without understanding which structure it specifies. By the time they consult a tax advisor, the structure may already be locked in, eliminating the most impactful planning opportunity.
