The tax structure of a business acquisition is one of the most consequential decisions in the transaction. The choice between an asset purchase and a stock (or entity interest) purchase determines how the purchase price is allocated for tax purposes, what depreciation and amortization deductions the buyer receives, and how the seller’s gain is characterized. Under IRC 1060, the purchase price in an asset acquisition is allocated using the residual method across seven asset classes, with any excess over tangible asset values assigned to goodwill and amortized over 15 years under IRC 197. The buyer and seller must both report the same allocation on Form 8594, which means the allocation is a negotiation point in the deal. The tax implications of the structure can represent 10-20% of the purchase price, making it one of the most valuable areas for tax planning.

✓Key takeaway

Asset purchase vs. stock purchase comparison:

Factor	Asset Purchase	Stock Purchase
What is acquired	Individual assets (equipment, inventory, customer lists, goodwill)	Shares of stock (or LLC/partnership interests)
Buyer’s basis	Stepped-up to purchase price (fresh depreciation)	Carryover basis (seller’s old depreciation continues)
Depreciation/amortization to buyer	Full, based on allocated purchase price	Limited (continues seller’s depreciation schedule)
Goodwill amortization (15-year, IRC 197)	Yes (buyer deducts)	No (unless IRC 338(h)(10) election)
Seller’s tax treatment	Mixed (ordinary on depreciation recapture, capital gains on goodwill)	Capital gains on entire gain (generally)
Buyer’s preference	Preferred (higher deductions)	Less preferred (lower deductions)
Seller’s preference	Less preferred (some ordinary income)	Preferred (all capital gains)
Liabilities	Buyer generally does NOT assume unknown liabilities	Buyer assumes ALL liabilities (known and unknown)
Contracts and licenses	Must be assigned (may need consent)	Transfer with the entity automatically

IRC 1060 asset allocation classes (residual method):

Class	Assets	Tax Treatment to Buyer
I	Cash and cash equivalents	No depreciation
II	Actively traded securities, CDs, foreign currency	No depreciation
III	Accounts receivable, mortgages, credit card receivables	Collected as income
IV	Inventory	Deducted as COGS when sold
V	All other tangible and intangible assets (equipment, furniture, vehicles, patents, customer lists, non-compete agreements)	Depreciated/amortized (5-15 years, depending on asset)
VI	IRC 197 intangibles (except goodwill and going concern)	Amortized over 15 years
VII	Goodwill and going concern value	Amortized over 15 years

How does the purchase price allocation work?

Hypothetical example

Round numbers. A buyer purchases a profitable plumbing business for $1,000,000. The business is operated as a C-Corp.

Fair market value of identifiable assets:

Asset	FMV
Cash in bank	$50,000
Accounts receivable	$80,000
Inventory (parts, supplies)	$40,000
Vehicles (5 trucks)	$150,000
Equipment and tools	$100,000
Customer list	$80,000
Non-compete agreement (seller, 5 years)	$50,000
Trade name and reputation	$50,000
Total identifiable assets	$600,000
Goodwill (residual)	$400,000
Total purchase price	$1,000,000

Buyer’s depreciation and amortization schedule (asset purchase):

Asset	Amount	Recovery Period	Annual Deduction
Vehicles ($150,000)	$150,000	5-year MACRS + 100% bonus	$150,000 (Year 1)
Equipment ($100,000)	$100,000	5-7 year MACRS + 100% bonus	$100,000 (Year 1)
Customer list ($80,000)	$80,000	15-year (IRC 197)	$5,333/year
Non-compete ($50,000)	$50,000	15-year (IRC 197)	$3,333/year
Trade name ($50,000)	$50,000	15-year (IRC 197)	$3,333/year
Goodwill ($400,000)	$400,000	15-year (IRC 197)	$26,667/year
Year 1 total deductions			$288,666
Years 2-15 annual deductions			~$38,666

Tax savings from asset purchase deductions:

Year	Deduction	Tax Savings (24% bracket)
Year 1	$288,666	$69,280
Years 2-15 (average)	~$38,666	~$9,280/year
15-year total deductions	$1,000,000	~$189,200

If the buyer had done a stock purchase instead:

Item	Stock Purchase
Buyer’s basis in assets	Seller’s carryover basis (e.g., $200,000 after depreciation)
Buyer’s Year 1 depreciation	~$10,000 (continuing seller’s schedule)
No goodwill amortization	$0
15-year total deductions	~$150,000
Tax savings	~$36,000

Comparison:

Metric	Asset Purchase	Stock Purchase
Year 1 deductions	$288,666	~$10,000
15-year total deductions	~$1,000,000	~$150,000
Total tax savings (24%)	~$189,200	~$36,000
Additional tax savings from asset purchase		$153,200

The asset purchase provides $153,200 more in tax savings over 15 years. This is why buyers strongly prefer asset purchases.

Seller’s tax treatment (asset sale):

Asset Class	Amount	Seller’s Tax Rate
Inventory ($40,000, cost basis $30,000)	$10,000 gain	Ordinary income (37%)
Vehicles ($150,000, adjusted basis $60,000)	$90,000 gain	Ordinary income (depreciation recapture, IRC 1245)
Equipment ($100,000, adjusted basis $0)	$100,000 gain	Ordinary income (depreciation recapture)
Customer list ($80,000, basis $0)	$80,000 gain	15% LTCG
Non-compete ($50,000, basis $0)	$50,000 gain	Ordinary income
Trade name ($50,000, basis $0)	$50,000 gain	15% LTCG
Goodwill ($400,000, basis $0)	$400,000 gain	15% LTCG
Total gain	$780,000	Mixed rates

Income Type	Amount	Rate	Tax
Ordinary income (recapture + non-compete + inventory)	$250,000	37%	$92,500
LTCG (goodwill + customer list + trade name)	$530,000	20% + 3.8% NIIT	$126,140
Total seller’s tax			$218,640

If the seller had done a stock sale instead:

Item	Amount
Stock sale price	$1,000,000
Stock basis	$200,000
LTCG	$800,000
Tax (20% + 3.8% NIIT)	$190,400
Savings vs. asset sale	$28,240

The seller saves $28,240 on a stock sale ($190,400 vs. $218,640). This is why sellers prefer stock sales: all gain is capital, with no depreciation recapture at ordinary rates.

Negotiating the structure: The buyer’s $153,200 in additional tax savings from an asset purchase exceeds the seller’s $28,240 in additional tax cost. The total tax pie is smaller with an asset purchase. The buyer can share some of the savings with the seller through a higher purchase price, creating a win-win.
