For employees, founders, and early investors in private companies, the path to liquidity has traditionally followed one route: wait for an IPO or an acquisition. In recent years, secondary markets for private company equity have expanded, creating a third option: selling shares to other investors before any formal liquidity event.
The appeal is real - employees who have accumulated significant paper wealth can realize some of that value without waiting for a company timeline that may be years away. But the secondary sale process involves a set of legal, tax, and valuation questions that are distinct from both public market stock sales and the standard equity compensation planning most employees are familiar with.
This article covers the main topics that a financial advisor, tax professional, and legal counsel work through with shareholders considering a secondary sale. The content is educational; the specific analysis for any given transaction requires qualified professionals reviewing the actual documents and circumstances.

What a Secondary Sale Actually Involves
A secondary sale of private company stock is a transaction in which an existing shareholder sells their shares to a new investor - a secondary fund, a direct buyer, or another party - rather than to the company itself (which would be a repurchase) or to the public (which requires a registered offering).
The mechanics depend heavily on the company's governance documents:
- Most private companies have a Right of First Refusal (ROFR) in their shareholder agreements. Before a shareholder can sell to a third party, the company - and sometimes other existing investors - have the right to purchase those shares on the same terms the third-party buyer has offered. This right can delay or block the transaction.
- Some companies have outright transfer restrictions that prohibit secondary sales without company consent. Understanding whether consent is required and whether the company is likely to grant it is a threshold question before any other analysis.
- The type of equity matters. Common stock held by employees or early investors may have different rights, preferences, and restrictions than preferred stock held by institutional investors. The class of shares being sold affects who will buy them and at what price.
Questions to address with an attorney before approaching any buyer:
- What does the shareholder agreement say about transfer restrictions and ROFR?
- Does the company have a formal secondary sale policy, and if so, what does it require?
- Are there any lock-up commitments, vesting conditions, or grant agreement restrictions that affect the ability to sell?
- If selling options rather than vested shares, does the transaction require exercising the options first, and what are the tax implications of doing so?
Valuation in a Private Market
In a public company, share price is determined continuously by the market. In a private company, there is no continuous market, and the price of secondary shares is established through negotiation between buyer and seller in the context of limited information.
Secondary buyers - typically specialized secondary funds or private wealth platforms - conduct their own valuation analysis based on the company's most recent 409A valuation, the last primary financing round's implied valuation, the company's disclosed financial metrics, and their own view of the company's prospects.
Topics to understand about secondary pricing:
- What is the company's last 409A valuation, and how does it relate to the last preferred stock round's implied common stock value? Common stock is typically worth less than preferred stock on a per-share basis due to the liquidation preferences of institutional investors.
- What discount are secondary buyers currently applying to the company's implied valuation, and why? Discounts of 20% to 40% below the last primary round valuation are not uncommon, depending on market conditions and the company's perceived trajectory.
- Is the company currently in a fundraising process or planning one? A company approaching a new round may have more or less clarity on value than one that last raised capital several years ago.
- Has the company recently issued a new 409A valuation, and does the transaction price create any tax complications relative to that valuation?
The SEC maintains resources on private company offerings and the securities law framework that applies to private share sales. Secondary sale transactions involving the offer or sale of securities must comply with applicable federal and state securities laws, even though the transaction is not a public offering.

Tax Treatment of Secondary Sales
The tax treatment of a secondary sale depends on the type of equity being sold, the holding period, and any special elections that may have been made at the time the equity was acquired.
For shares of common stock held outright (not options), the gain is calculated as the sale price minus the cost basis. If the shares have been held for more than one year, the gain is typically treated as long-term capital gain. If held for less than one year, the gain is short-term and taxed at ordinary income rates.
For shares acquired through stock option exercises, the basis and character of the gain depend on the type of option:
- For NSOs exercised in the past, the basis is the fair market value on the date of exercise (which was already taxed as ordinary income). The gain from sale price to basis is capital gain, long-term if the shares have been held for more than one year from exercise.
- For ISOs exercised and held through the required holding periods, the gain from exercise price to sale price is long-term capital gain - but only if both the one-year-from-exercise and two-year-from-grant holding periods have been met.
- For ISOs exercised but sold before meeting the holding periods (a disqualifying disposition), the gain between exercise price and FMV on date of exercise is treated as ordinary income, with the remaining gain capital gain.
Questions to address with a tax advisor before any secondary sale:
- What is the basis in each lot of shares being considered for sale, and what holding period applies?
- What is the estimated tax liability from the sale, including federal, state, and Net Investment Income Tax?
- Are there any state-specific rules - particularly for states where the company operates or is incorporated - that affect the tax treatment?
- Is there a strategy for timing the sale across tax years to manage the liability?
The IRS provides guidance on stock option tax treatment and capital gains that forms the technical foundation for this analysis.
For shareholders with meaningful equity positions who are evaluating a secondary sale, an equity liquidity advisor who specializes in private company equity transactions can coordinate the legal, tax, and financial planning dimensions. The advisor match page describes how Capivise matches investors based on the specific characteristics of their equity position. The questions to ask an advisor page covers the pre-engagement framework relevant to any advisor working in this area.

Practical Platforms and Process
Secondary sales of private company equity are typically facilitated through one of several channels:
- Direct outreach to known secondary buyers: specialized secondary funds that focus on private company equity and transact regularly in specific sectors or stages.
- Secondary marketplaces: platforms that facilitate introductions between sellers and buyers of private company equity. These platforms vary in their requirements, the types of companies they cover, and their process for handling ROFR notifications.
- Company-facilitated secondary programs: some private companies run formal secondary programs at specific intervals, often tied to a primary financing round. These programs manage the ROFR process and provide pricing clarity.
Each channel has different costs, different disclosure requirements for the seller, and different expectations about confidentiality. A legal advisor familiar with securities law for private transactions should review any secondary transaction before it proceeds.
The FINRA BrokerCheck tool is useful for verifying the registration status of any platform or individual facilitating the transaction who is a registered broker-dealer. The SEC has published guidance on the broker-dealer registration requirements that apply to secondary market platforms for private company equity.
What Secondary Sales Do Not Solve
For shareholders who are primarily concerned about concentration risk - holding most of their net worth in a single company's equity - a secondary sale solves the liquidity problem for the shares sold but does not address the concentration in the remaining shares, options, and unvested grants.
A coherent approach to private company equity concentrations involves:
- A deliberate plan for how much of the total position to sell, in what stages, and on what timeline.
- A strategy for the after-tax proceeds - where they go and how they are invested to reduce concentration in the overall portfolio.
- A framework for evaluating future secondary sale opportunities as additional shares vest or as the company's valuation evolves.
The SEC's investor resources cover portfolio diversification from concentrated positions. The tax-efficient reinvestment advisor matching at Capivise addresses the investment planning for proceeds after a secondary sale or other liquidity event. NAPFA provides a directory of fee-only advisors with fiduciary commitments who can address the full portfolio picture.
Secondary sales are not the right move for every shareholder in every situation. For shareholders who believe strongly in the company's trajectory, the discount at which secondary sales typically transact may not justify the liquidity. For those with financial needs, significant concentration risk, or a timeline that does not align with the company's expected IPO or acquisition, a secondary sale may be worth pursuing despite the discount. Working through that analysis with a qualified advisor - rather than making the decision based on a single offer or a colleague's experience - is what produces a decision the shareholder can stand behind.
