LA Deal Maker or Breaker: The §338(h)(10) Election in Business Purchase and Sale
When negotiating the sale of a business in Los Angeles, California, one tax strategy often determines whether a deal succeeds or fails: the Section 338(h)(10) election. This powerful tax provision bridges the gap between buyer and seller priorities:
- Buyers want tax deductions and a stepped-up basis.
- Sellers want to minimize taxes and maximize after-tax proceeds.
With over 20 years of dedicated M&A experience, the attorneys at Simantob Law Group specialize in modeling and negotiating this election, turning a complex tax rule into millions in added value for our Southern California clients.
The §338(h)(10) Solution in Los Angeles M&A
Most Los Angeles business sales involve S Corporations or subsidiaries holding valuable assets like real estate, technology, and proprietary client lists.
The Fundamental M&A Tax Conflict
In a stock sale, the seller benefits from lower capital gains tax, but the buyer inherits the company’s existing tax basis, limiting future deductions. In an asset sale, the buyer gains a stepped-up basis for depreciation and amortization, but the seller faces higher ordinary income tax. The §338(h)(10) election combines the best of both worlds: it preserves the legal simplicity of a stock sale while granting the buyer asset-sale tax benefits. To balance the seller’s increased tax burden, a negotiated tax gross-up ensures they receive their intended after-tax proceeds.

Tax Optimization (Win-Win) |
The §338(h)(10) election solves this by:
- Legally executing a stock sale (preserving contracts, permits, and continuity—critical in LA’s competitive and regulated environment).
- Treating it as an asset sale for tax purposes.
Result: Buyer gets tax benefits of an asset sale; Seller is compensated through a tax gross-up in the purchase price.

The Financial Mechanics: ADSP, AGUB, and Goodwill
Our two decades of experience have shown that a successful §338(h)(10) election hinges on calculating two crucial, but different, formulas:
1. Seller’s Tax Calculation: Aggregate Deemed Sale Price (ADSP)
The ADSP is the final price the Old Target company is deemed to have sold its assets for. It determines the seller’s tax liability.
ADSP=Purchase Price+Assumed Liabilities+Tax on Sale
This formula is circular because the tax owed is based on the ADSP, which itself includes the tax! This requires specialized algebraic modeling to solve for the final, correct tax liability.
2. Buyer’s Tax Benefit: Adjusted Grossed-Up Basis (AGUB) (H3)
The AGUB is the total new tax value the buyer can assign to the assets for future deductions.
AGUB=Purchase Price+Assumed Liabilities
Allocation to Goodwill (The Buyer’s Jackpot) (H3)
The AGUB is allocated to the acquired assets using a mandated sequence. The most desirable outcome for the buyer is a large residual amount allocated to Goodwill, which is fully amortizable (written off) over 15 years.

Numeric Example: How the Step-Up Creates Value
Assume the AGUB (Buyer’s New Basis) is $12,000,000, and the Old Target’s tax value (Inside Basis) was only $3,000,000. This creates a $9,000,000 tax basis step-up.
- Buyer’s Tax Benefit:
- The AGUB is allocated, resulting in $6,000,000 assigned to Goodwill.
- This creates a $400,000 annual deduction ($6,000,000 ÷ 15) for the buyer for 15 years.
- The Present Value (PV) of these tax savings often amounts to over $1,000,000, justifying the gross-up payment to the seller.
- Seller’s Tax Impact:
- The seller’s immediate tax bill is higher due to the ADSP.
The Solution: Simantob Law Group negotiates a tax gross-up so the buyer pays a bonus that precisely offsets this increased tax, ensuring the seller nets their intended after-tax proceeds.

Navigating the California FTB Trap
For the sale of a business in Los Angeles, California, the election is complicated by the Franchise Tax Board (FTB). Our over 20 years of M&A experience in California is critical here.
Apportionment Risk
While the FTB generally respects the federal election, their rules for apportioning (dividing) the deemed sale gain can create unexpected tax bills for multi-state businesses. The FTB’s rules can exclude the large sale receipts from the sales factor, potentially causing a disproportionately higher percentage of the gain to be taxed in California.
Our Expert Strategy
We draw on decades of experience to model these complex state tax scenarios and negotiate full tax gross-up provisions that shield our clients from the incremental federal and California tax hit resulting from the election, ensuring our clients receive maximum net proceeds.
