About the Author: I come from a Big 4 (EY) and Private Equity (Morgan Stanley) background and have helped clients buy and sell small businesses for years. One of the most consistently misunderstood things I see first-time buyers get steamrolled on is deal structure.
The Two Deal Structures at a Glance
Asset Deal
What buyers almost always want
- Step-up in basis on all assets
- New depreciation schedule from purchase price
- Tax shields start year one
- Control over purchase price allocation
- Potential $40-80K+ in tax savings over 5 years
Stock Deal
What sellers typically push for
- Inherit seller's old depreciation schedule
- No step-up in basis
- Equipment worth $0 on books stays at $0
- Pay $500K but get almost no deductible basis
- Seller pays only 15-20% capital gains
The Math: Why Asset Deals Save You Money
When you buy assets, you get what's called a step-up in basis. The purchase price gets allocated across assets (equipment, inventory, goodwill, non-compete agreements) and you depreciate those from the new (higher) value going forward.
Example: $500K Landscaping Company
Seller's Books
$0
Equipment fully depreciated
Your Asset Deal Allocation
$150,000
New depreciable equipment basis
$30,000
Annual depreciation (5-year)
37%
Marginal tax rate
~$55,000
Total tax savings
In a Stock Deal, You Get None of This
You inherit the seller's old depreciation schedule. The equipment is still worth $0 on the books, and you get $0 depreciation expense to offset business income. You paid $500K for the business and get almost no deductible basis from it.
Why Sellers Push for Stock Deals
Because their tax bill is dramatically lower.
Stock Deal (Seller's Preference)
Tax treatmentLong-term capital gains
Federal rate15-20%
ComplexityClean, one tax event
Asset Deal (Seller's Nightmare)
Tax treatmentSplit by asset class
Depreciation recaptureUp to 37%
Extra tax hit$30-60K+
Translation: When a seller says "I need it to be a stock deal," what they're really saying is: "I don't want to pay an extra $30-60K in taxes." That's their problem, not yours — but it becomes your problem if you concede it without negotiating a price adjustment.
The Bridge: 338(h)(10) Elections
If you're buying an S-corp (very common in SMB), there's a tax election called a 338(h)(10) that lets both parties treat the deal as an asset sale for tax purposes while keeping the legal structure of a stock sale.
When It Works
- S-corporations
- Both parties agree to the election
- Seller accepts price bump for tax hit
When It Doesn't Work
- C-corporations (doesn't work cleanly)
- LLCs taxed as partnerships
- Seller refuses to agree
If you're looking at an S-corp and the seller won't budge on stock deal, this is worth bringing to the table.
The Allocation Fight Nobody Warns You About
Even when both sides agree to an asset deal, the allocation of purchase price is its own negotiation. The IRS requires both parties to file consistent allocations (Form 8594), and how you split the number across asset classes affects both of your tax outcomes.
As a Buyer, Maximize Allocation To:
- Equipment / FF&EFast depreciation, bonus depreciation available
- Non-compete agreementsAmortized over 15 years, but deductible
- Working capital assetsStep-up carries through
Note: Minimize allocation to goodwill — not because it's bad, but because equipment depreciates faster and creates more near-term cash tax savings.
The Seller Wants the Opposite:
- Maximize goodwillCapital gains treatment (15-20%)
- Minimize equipmentAvoids depreciation recapture (37%)
- Low non-compete allocationOrdinary income treatment
Warning: This is a real negotiation and most buyers don't even know it's happening.
Key Takeaway
Before you get anywhere near LOI, know what entity type you're buying and get your CPA in the room. Not just for due diligence, but to model the after-tax purchase price under both structures.
