Founders and boards usually approach secondary sales as a liquidity design problem: who should be allowed to sell, how much, at what price, and to whom. That is necessary, but incomplete. The same transaction can produce very different tax outcomes depending on who the buyer is, whether the company is paying a premium, and whether the repurchase looks like a real sale, compensation, or dividend-like treatment.
Montague’s live article on late-stage startup liquidity explains the broader board-level reasons companies create liquidity programs. This article is narrower. It focuses on a founder-side problem that often appears only after the business terms feel settled: what if the tax treatment is not what everyone assumed?
1. Premium pricing can trigger a compensation analysis
If the company repurchases stock from service providers at a price materially above what is supportable as fair market value, the excess may be viewed as compensation rather than pure capital gain. That is not just a seller problem. If the payment is compensation, the company may have withholding obligations and payroll consequences that were not built into the supposed “liquidity event.”
The risk becomes sharper where participation is limited mainly to employees or a selected group of insiders, where the premium appears retention-driven, or where the company itself is the buyer. The more the economics resemble a company-delivered employee benefit, the harder it becomes to defend the payment as simple sale proceeds.
2. Company repurchases may raise dividend-style questions too
Even if a repurchase is not treated as compensation, the seller may still need to analyze whether the transaction is actually treated as a sale or instead as a dividend-like redemption under the tax rules. Partial repurchases can be particularly tricky because tax treatment may depend on how much ownership is actually reduced and whether the statutory redemption tests are satisfied.
That means “we let employees sell a slice” is not tax analysis. It is a business description that still needs tax modeling.
3. Buyer identity matters
There is a meaningful difference between a third-party investor buying shares in a negotiated secondary and the company buying back shares directly. Existing insiders or investor groups can raise additional questions too. If the structure appears designed to transfer economic value to employees while preserving the company’s preferred control outcome, the tax characterization can become less intuitive than the term sheet suggests.
4. Tender-offer and process issues can sit alongside the tax analysis
Once a liquidity program broadens beyond a handful of negotiated sellers, securities-law process considerations may become harder to ignore. Boards and deal teams should not assume a wider company-facilitated repurchase is merely a contract matter. That is why tax, securities, and cap-table planning should be handled together rather than in separate silos.
The SEC’s Tender Offer Rules and Schedules guidance is a useful starting point when the structure begins to resemble a formal offer rather than a one-off transfer.
5. Copy-and-paste liquidity tax diligence list
SECONDARY SALE / BUYBACK TAX DILIGENCE LIST (STARTER) 1. Who is buying the shares? - company - existing investor - new investor - mixed buyer group 2. Who can participate? - current employees only - former employees - founders - advisors / consultants - non-service-provider stockholders 3. How was the price set? - preferred round price - discount to preferred - 409A reference point - negotiated premium 4. Does any portion of the price risk being treated as compensation? 5. Could the repurchase be analyzed as dividend-style treatment rather than sale treatment? 6. Are payroll withholding, information reporting, or employment tax issues implicated? 7. Does the structure raise tender-offer or broader securities-law process questions? 8. Has outside tax advice been obtained on the final structure rather than only the concept?
6. Practical risk indicators
- The company is the buyer and pays meaningfully above the latest supportable common value.
- Only employees or selected executives get the premium opportunity.
- The board is motivated partly by retention but the documents treat the whole payment as capital gain by assumption.
- The company is repurchasing only part of a seller’s position without analyzing redemption treatment.
- The structure is broad enough to raise tender-offer style process questions, but no one has owned that workstream.
7. Where founders usually misread the problem
Many teams assume the tax answer follows the commercial label. If everyone calls it a “secondary sale,” they assume it is taxed like a sale. If the repurchase is positioned as founder-friendly liquidity, they assume that intent helps. It often does not. Tax and securities characterization depend on facts, structure, and execution details—not the room’s preferred narrative.
Bottom line
Liquidity programs can be valuable tools. But premium pricing, company repurchases, and partial buybacks deserve real tax analysis before the board announces a solution. The earlier the company models compensation risk, redemption treatment, and process obligations, the less likely the program is to create a cleanup project right when the business is trying to create goodwill.
