Many founder teams discover the tax problem too late: after the buyer and seller have fallen in love with a structure for business reasons, after the letter of intent uses shorthand that hides the real economics, or after the tax advisors are asked to “bless” a deal architecture that already has momentum.
The objective of this article is not to replace transaction tax advice. It is to help founders recognize the questions that change economics early enough to matter—especially the tension between buyer preference for basis step-up and seller preference for cleaner, single-level taxation.
If those questions are framed before the LOI hardens, the parties have more room to trade price, structure, elections, indemnities, and timing intelligently.
In this guide
- Why the same purchase price can produce very different after-tax results
- How buyers and sellers usually see asset treatment differently
- When elections and allocation mechanics matter
- A copy/paste issue memo for founders to send to tax advisors
The buyer and seller often want opposite things
A buyer often likes asset treatment because basis step-up can improve depreciation and amortization and reduce future taxable gain. A seller often prefers stock treatment because it can avoid the double-tax pattern that shows up in many taxable asset-style exits. The same tension appears when forward or forward triangular mergers are compared to reverse triangular mergers.
That does not mean one side is “right.” It means structure is part of the economics. If the buyer wants tax treatment that increases seller tax cost, the seller should expect that issue to show up in price, gross-up demands, indemnities, or election negotiations.
- Forward and forward triangular mergers often feel more asset-like for tax purposes.
- Reverse triangular mergers more often feel stock-like for tax purposes.
- State transfer taxes, entity classification, and shareholder profile can change the answer fast.
Elections and allocation mechanics can move real dollars
If a transaction is treated as an asset acquisition, the parties may need to think about purchase-price allocation and the reporting tied to IRS Form 8594. If a qualified stock purchase is involved, elections under IRS Form 8023 and the asset-allocation reporting described in Form 8883 guidance can change how the deal is taxed.
For founders, the practical takeaway is simple: do not wait until the signature draft to ask whether the buyer expects asset treatment, whether a Section 338 election is contemplated, or whether any related election shifts tax cost back to the seller.
Tax attributes and timing do not save every structure
Net operating losses, entity basis, shareholder basis, installment notes, and rollover equity can all complicate the math. Sometimes legacy NOLs soften entity-level pain. Sometimes Section 382 or related limitations narrow the real value of those attributes. Sometimes an election that looks attractive to the buyer is painful to the seller because it changes the character or amount of recognized gain.
That is why this analysis should be paired with Montague’s guides on startup tax traps before fundraising and the startup secondary-sales tax checklist. Different transaction types create different tax paths, but the common theme is the same: early framing beats late cleanup.
Use the LOI to surface the tax conflict early
The LOI does not need a tax treatise. It should, however, avoid locking the parties into a structure by inertia. At minimum, founders should know whether the draft contemplates stock, assets, or merger treatment; whether the buyer expects cooperation on elections; whether the allocation of consideration will be a negotiated schedule; and whether tax cost sharing is expected.
The earlier that work happens, the easier it is to price the tradeoff instead of litigating it through the purchase agreement.
