Unquoted shares are ownership stakes in companies that don’t trade on a public stock exchange like the NYSE or Nasdaq. Because there’s no live market price, the shares are valued by professional appraisal, sold only to buyers who meet federal eligibility rules, and transferred under contractual and regulatory restrictions that can take months to work through. If you own them or are thinking about buying in, the practical questions are the same: how is the price set, who’s allowed to buy, how do you sell, and what does the tax code do with them.
How Unquoted Shares Differ From Public Stock
The biggest practical difference is liquidity. You can sell publicly traded shares in seconds during market hours at a price everyone can see. Selling unquoted shares means finding a buyer on your own, negotiating a price without a public benchmark, and clearing contractual restrictions that may limit who you can sell to. That process can take months.
Information is the second gap. Public companies file quarterly and annual reports with the SEC, giving any investor access to standardized financial data. Private companies face far lighter disclosure rules. You’ll usually see financial statements only if you’re already a shareholder, and those statements may not follow the same auditing standards. If you’re considering buying in, the burden of investigating the company’s finances falls on you.
The regulatory framework is also different. Public offerings must be registered with the SEC under the Securities Act of 1933, which imposes detailed disclosure and anti-fraud requirements.1Legal Information Institute. Securities Act of 1933 Private companies sidestep full registration by relying on exemptions, most commonly Regulation D, which lets them raise unlimited capital without going through the public offering process.2U.S. Securities and Exchange Commission. Exempt Offerings The tradeoff: these exemptions restrict who can invest and how shares can later be resold.
Who Can Buy Unquoted Shares
Most private placements under Rule 506 of Regulation D are limited to accredited investors.3U.S. Securities and Exchange Commission. Private Placements – Rule 506(b) The SEC sets specific financial thresholds to qualify:
- Income of more than $200,000 individually (or $300,000 jointly with a spouse or partner) in each of the prior two years, with a reasonable expectation of the same in the current year.
- Net worth exceeding $1 million, excluding the value of your primary residence, either individually or jointly.
- Certain securities licenses (Series 7, Series 65, or Series 82) in good standing, which qualify you regardless of income or net worth.
These thresholds exist because unquoted shares carry risks public market investors don’t face: limited information, no guaranteed exit, and the possibility that the company never reaches a liquidity event.4U.S. Securities and Exchange Commission. Accredited Investors Under Rule 506(b), a company can also sell to up to 35 non-accredited investors, but must provide them with more extensive disclosure documents.
How the Price Is Set Without a Ticker
With no exchange quoting a price, a qualified independent appraiser estimates what a willing buyer would pay a willing seller. The number matters for issuing stock options, filing estate tax returns, negotiating a sale, and resolving disputes among shareholders. Appraisers draw on three recognized approaches and weigh the results based on which best fits the company.
The Market Approach
The market approach asks what similar companies have sold for recently. The appraiser identifies comparable private transactions or publicly traded companies in the same industry, then applies their valuation multiples (revenue, earnings, or similar metrics) to the subject company. When public comparables are used, the appraiser must adjust downward because a private company’s shares can’t be sold as easily. That adjustment is called the Discount for Lack of Marketability, and it typically runs 30% to 50%. The discount reflects a straightforward reality: investors pay less for an asset they can’t quickly convert to cash.
The Income Approach
The income approach, usually executed as a discounted cash flow analysis, projects the company’s expected future cash flows and calculates what those future dollars are worth today. The discount rate is often the company’s weighted average cost of capital, which accounts for the risk investors take. A higher rate means more risk and a lower present value. Small changes in the growth rate or discount rate can swing the final number dramatically, which is why most valuation disputes land here.
The Asset Approach
The asset approach adds up the fair market value of everything the company owns, tangible and intangible, then subtracts liabilities. It works best for companies whose value sits in hard assets like real estate, equipment, or inventory, and it’s the standard method when a company is winding down.
Weighting and the Preferred-Common Gap
For a capital-intensive manufacturer, the asset approach may carry the most weight. For a software company with minimal physical assets but strong recurring revenue, the income and market approaches drive the number. The final valuation is often a weighted blend, presented as a range rather than a single precise figure.
One distinction matters inside the capital structure. Venture-backed companies typically issue preferred shares to investors and common shares to founders and employees. Preferred shares carry liquidation preferences, meaning those holders get paid first (often at a guaranteed multiple of their investment) before common shareholders see anything in a sale or liquidation. A 1x liquidation preference is standard; 2x or 3x preferences appear in tougher fundraising environments. Common shares in the same company are worth less than preferred, and any credible valuation reflects that gap.
409A Valuations and Employee Stock Options
Any private company that grants stock options to employees must set the exercise price at or above the stock’s fair market value on the grant date. Section 409A of the Internal Revenue Code governs this requirement, and the penalties for underpricing are severe: the employee owes a 20% additional tax on top of regular income tax, plus interest calculated from the year the options were granted.5Office of the Law Revision Counsel. 26 USC 409A – Inclusion in Gross Income of Deferred Compensation The employee bears that tax hit even though the company set the price.
To avoid that outcome, private companies obtain a 409A valuation from an independent appraiser. An appraisal by a qualified third party creates a safe harbor presumption that the IRS can only challenge by showing the valuation was grossly unreasonable.6eCFR. 26 CFR 1.409A-1 – Definitions and Covered Plans The appraisal must be no more than 12 months old at the time options are granted, and any material event in the meantime (a new funding round, a major acquisition, a sharp shift in revenue) requires an immediate update regardless of timing.
Selling Unquoted Shares
Selling isn’t as simple as placing a market order. The company’s shareholder agreements almost always impose procedural hurdles before any transfer, and federal securities law adds its own timeline.
Transfer Restrictions in the Shareholder Agreement
The most common restriction is the right of first refusal. Before you can sell to an outside buyer, you must offer your shares to the company or existing shareholders at the same price and on the same terms the outside buyer agreed to.7U.S. Securities and Exchange Commission. Right of First Refusal and Co-Sale Agreement – Provention Bio, Inc. Only after they decline can you proceed with the third-party sale. This protects the company from unwanted outsiders joining the shareholder roster and slows down your exit.
Two other provisions appear often. Tag-along rights let minority shareholders sell on the same terms when a majority holder sells, so they aren’t left behind in a deal they didn’t choose. Drag-along rights work the other direction, allowing a majority shareholder to force minority holders into a sale. Both prevent situations where a partial buyout leaves some shareholders stuck or a buyer walks because they can’t acquire full ownership.
Rule 144 Holding Periods
Even after clearing contractual restrictions, federal law imposes a holding period. Under SEC Rule 144, if the issuing company files regular reports with the SEC, you must hold restricted shares for at least six months before reselling them. If the company doesn’t file those reports, which covers most private companies, the holding period extends to one year.8eCFR. 17 CFR 230.144 – Persons Deemed Not to Be Engaged in a Distribution The clock doesn’t start until you’ve fully paid for the shares.9U.S. Securities and Exchange Commission. Rule 144 – Selling Restricted and Control Securities
Tax Rules That Apply Only to Private Shares
Several provisions of the Internal Revenue Code apply specifically to shares in small or closely held companies. Used correctly, they can be worth significant money. Mishandled, they create tax bills that didn’t need to exist.
Qualified Small Business Stock (Section 1202)
If you hold shares in a qualifying C corporation with gross assets under the statutory threshold, Section 1202 allows you to exclude a portion of your capital gains from federal tax when you sell.10Office of the Law Revision Counsel. 26 USC 1202 – Partial Exclusion for Gain from Certain Small Business Stock The rules changed under the One Big Beautiful Bill Act in mid-2025, so when the stock was issued matters.
For shares issued before July 5, 2025, holding for more than five years qualifies you for up to a 100% exclusion, capped at the greater of $10 million or ten times your adjusted basis. For shares issued after July 4, 2025, the exclusion phases in: 50% after three years, 75% after four, and 100% after five. The per-issuer cap rises to $15 million for post-OBBBA stock (indexed for inflation starting in 2027), and the company’s gross asset ceiling increases from $50 million to $75 million. Gain on shares held only three or four years that isn’t excluded is taxed at 28% rather than the usual long-term capital gains rates.
Qualification is strict. The company must be a domestic C corporation, you must have acquired the stock at original issuance rather than on a secondary market, and the company must use at least 80% of its assets in an active trade or business. Certain industries, including finance, hospitality, and professional services, are excluded.
Section 1244 Losses
Not every investment works out. Section 1244 lets you treat losses on qualifying small business stock as ordinary losses rather than capital losses. The difference is substantial: ordinary losses offset regular income dollar for dollar, while capital losses are capped at $3,000 per year against ordinary income, with the rest carried forward. The annual limit on ordinary loss treatment is $50,000 for individual filers or $100,000 on a joint return. To qualify, the corporation must have received no more than $1 million in total capital contributions when the stock was issued.11Office of the Law Revision Counsel. 26 USC 1244 – Losses on Small Business Stock
The Section 83(b) Election
Founders and early employees often receive restricted stock that vests over time, typically on a four-year schedule. Without any special election, you owe ordinary income tax on the shares as they vest, based on fair market value at each vesting date. If the company’s value has climbed since you received the shares, that tax bill grows with every vesting milestone.12Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection with Performance of Services
Filing a Section 83(b) election flips that. You pay ordinary income tax immediately on the value of the shares at the time of the grant, which for a brand-new startup is often close to zero. All future appreciation is then taxed at capital gains rates when you eventually sell, rather than as ordinary income at each vesting date. The catch: you must file within 30 days of receiving the shares, with no extension and no do-over.13Internal Revenue Service. Instructions for Form 15620, Section 83(b) Election Miss the window and you’re locked into the default treatment for that grant.
The risk runs both ways. If you file the election and later forfeit the shares, say by leaving before vesting, you don’t get a refund on the tax you already paid. The election is a bet that the shares will be worth more later and that you’ll stay long enough to keep them.
