California business sales structure as either asset sales or stock sales (or membership-interest sales for LLCs). The choice has material tax, liability, and operational implications for both buyer and seller. This guide covers how California sellers should think through the choice.
Asset sale basics
Buyer purchases specific assets (equipment, customer list, inventory, IP) and assumes specific liabilities. Seller retains the entity. Buyer gets stepped-up basis in acquired assets (depreciation benefit). Seller pays tax on gain at entity level (if C-corp) plus dividend tax on distribution, or directly at owner level (if pass-through).
Stock sale basics
Buyer purchases ownership equity. The entity continues with all assets and liabilities. Seller pays capital gains directly on the gain. Buyer doesn't get stepped-up basis (loses depreciation benefit going forward). Buyer assumes all historical liabilities (including unknown ones).
California tax implications
Asset sales: California taxes gain at the entity level (for C-corps) plus owner level on distribution. Pass-through asset sales tax through to owner. Stock sales: California taxes capital gains at the owner level only. California does NOT have a preferential capital gains rate — gains taxed at ordinary income rates up to 13.3%.
Why most California small-business deals are asset sales
Buyers strongly prefer asset sales for liability protection and depreciation benefit. Most $300K–$2M California deals close as asset sales. SBA-financed deals especially favor asset structure. Sellers typically accept asset structure but negotiate purchase-price allocation aggressively to favor lower-tax categories.
When stock sales make sense
When the business has valuable contracts that don't transfer (or are difficult to transfer), specific licenses, or accumulated tax attributes (NOLs). Some professional practices (CA medical, dental under MSO) can only transfer through entity sale due to Corporate Practice of Medicine. Some real estate-heavy operations.
Section 1060 allocation
Asset sales require IRS Form 8594 reporting. Buyer and seller must agree on purchase price allocation across asset classes. Sellers benefit from allocating to capital-gain treatment categories (goodwill, customer list); buyers benefit from allocating to depreciable categories (equipment, inventory). This is heavily negotiated.
