Section 338(h)(10) Election: The Tax Magic Merger
Key Takeaway
Section 338(h)(10) is a legal "magic trick" in the US Tax Code. It allows a Buyer to purchase 100% of a company's Stock (which is legally clean and simple) but treat it as an Asset Purchase for tax purposes. This allows the Buyer to "Step-Up" the tax basis of the target’s assets to the purchase price, creating millions in new depreciation and amortization deductions that act as a massive post-deal tax shield.

🔄 The 338(h)(10) Flow: The Step-Up Logic
How to buy a company and "delete" its old tax history:
The Mechanics: Step-Up and Goodwill
The power of 338(h)(10) lies in the ability to "Resurrect" dead tax deductions.
1. The "Step-Up" in Basis
In a normal stock deal, the Buyer inherits the target's old "Basis" (the original cost of the equipment/patents). If the target bought a factory for $1M twenty years ago, the Buyer can only depreciate what's left of that $1M. Under a 338(h)(10) election, the Buyer "Steps-Up" the basis to the Fair Market Value (the price they just paid). If they paid $10M, they can now depreciate $10M, creating a massive cash flow benefit.
2. Section 197 Goodwill Amortization
In a stock deal, "Goodwill" (the premium paid over asset value) is a "dead" asset for tax purposes. You can't deduct it. However, because a 338(h)(10) is treated as an asset sale, the Goodwill is classified as a "Section 197 Intangible." This allows the Buyer to deduct the entire premium over 15 years, effectively getting a 21% refund (at current tax rates) on the extra money they paid for the brand.
🚩 Forensic Red Flags: The "Tax Trap" Signal
Forensic analysts look for these signs that a 338(h)(10) deal is structured to hide risks:
- The "Double Tax" (338(g) Mistake): If the Buyer files a Section 338(g) election instead of (h)(10) on a C-Corp, it triggers a double tax (at the corporate and shareholder level) that can consume 50%+ of the deal value. This is the ultimate "Rookie Error" in M&A.
- Excessive Asset Allocation to "Recapture" Items: If the Buyer and Seller disagree on how much of the price is for "Equipment" (which triggers immediate tax for the seller) vs. "Goodwill" (which doesn't). Discrepancies here can lead to IRS audits.
- The "Ineligible" Target: Trying to use 338(h)(10) on a standard C-Corp. The law only allows this election for S-Corps or Subsidiaries of a consolidated group. If the target is a regular public company, the election is invalid.

Frequently Asked Questions (FAQ)
Why would a Seller agree to this?
They usually don't want to because it can increase their taxes (Recapture Tax). The Buyer must "Gross-Up" the purchase price (pay more cash) to make the Seller "Whole."
Is it a "Legal Fiction"?
Yes. The IRS literally allows you to say: "For legal reasons, this is a stock sale (easy). For tax reasons, this is an asset sale (profitable)."
What is "Section 336(e)"?
It is the modern, more flexible cousin of 338(h)(10) that allows similar tax benefits even if the buyer isn't a corporation.
Conclusion: The Financial Engineering of Tax
The Section 338(h)(10) election is the financial engineering masterpiece of the tax code. It proves that in multi-million dollar mergers, the "Label" you put on a transaction is just as important as the cash you pay. By using a legal fiction to transform a stock purchase into a massive tax break, corporate leaders ensure that every dollar spent on an acquisition is maximized for future cash flow—proving that in the end, the most important partner in a merger is the one who writes the tax laws.

Bilingual Summary: Section 338(h)(10) is a "Tax Magic Trick." Stock sale on the outside, asset sale on the inside. 第 338(h)(10) 条税收选择是“税务魔术”。法律上是股票交易，税务上是资产交易。这种机制展示了买方如何通过这项联名选择，在法律上完整收购目标公司股权（保持法律主体的连续性），但在税务上将目标资产的账面价值“提步”（Step-up）至购买价格。这创造了巨额的折旧与摊销抵税额（Tax Shield），尤其是针对原先无法抵税的商誉（Goodwill）。理解“税收回收”（Recapture Tax）带来的价格溢价（Gross-up）博弈，是透视中型市场 M&A 与 S-Corp 收购架构设计的核心。
