An equity interest is an ownership stake in a business. Holding one gives you a claim on the company’s profits and, if the business is ever sold or wound down, on whatever assets are left after every debt has been paid. That claim can be worth a fortune or nothing at all. Equity owners absorb the risk of loss and capture the upside of growth, which is the tradeoff that separates owning a business from lending to one.
Equity Compared to Debt
The cleanest way to see what equity is comes from comparing it with debt. A lender hands the company cash and gets back a fixed amount plus interest on a set schedule. The return is capped; the maturity date is written down. An equity holder owns a piece of the company itself. No guaranteed return, no maturity date, no contractual right to get the original investment back on any particular timeline. The payoff comes from how the business actually performs.
The difference is starkest when a company fails. In a liquidation or bankruptcy, federal law sets a strict payment order: secured creditors, then unsecured creditors, then penalties and fines, then interest on those claims. Only after every one of those categories is paid in full does anything reach equity holders.1Office of the Law Revision Counsel. 26 USC 726 – Distribution of Property of the Estate In practice, equity holders in a liquidation frequently receive nothing.
What Equity Looks Like in Different Business Structures
The form your ownership takes depends on how the business is organized. The legal structure determines how standardized the stake is, how it transfers, and how much of it can be customized.
Corporations
Corporate equity takes the form of shares of stock. Shares are standardized units built for relatively easy transfer. Corporations typically issue two classes. Common stock carries voting rights and a residual claim on assets, meaning common holders get whatever is left after everyone else in the priority stack has been paid. Preferred stock trades voting power away for economic protections such as a fixed dividend and a higher position in the payout order during a sale or dissolution. The specific terms of preferred stock sit in the corporate charter and vary widely from one company to the next.
Limited Liability Companies
Equity in an LLC is called a membership interest, and membership interests are highly customizable.2Internal Revenue Service. Limited Liability Company (LLC) The operating agreement, a private contract among the members, controls almost everything: how profits are split, who makes management decisions, and what happens when someone wants to leave. Profits don’t have to follow ownership percentages. Two members could each own 50% but agree that one receives 70% of profits for the first five years in exchange for putting in more cash upfront. That flexibility is the main reason many private businesses choose the LLC structure. The tradeoff is that membership interests are harder to sell, because no two are alike and any buyer needs to read the operating agreement to see what they’d actually be getting.
Partnerships
Partnership equity is a partnership interest, and each partner has a capital account tracking contributions, withdrawals, and accumulated earnings. General partners run the business and accept personal liability for its debts. Limited partners are passive investors whose exposure is capped at what they contributed.3Internal Revenue Service. Partnerships The partnership agreement governs how profits, losses, and management authority are divided. Like LLC interests, partnership interests are difficult to transfer and usually require the consent of the other partners.
What Rights Come With Equity
Owning a stake is not just about receiving money. It brings a bundle of rights, and the specifics depend on the entity and on the governing documents.
Voting and Control
Corporate shareholders vote to elect the board of directors and weigh in on major transactions such as mergers or the sale of substantially all company assets.4Investor.gov. Shareholder Voting This is the primary channel for owners to influence the business, even though day-to-day operations are handled by the board and the officers it appoints. In an LLC, voting rights are whatever the operating agreement says they are. Some LLCs allocate votes by ownership percentage, others give each member one vote regardless of stake, and some vest all management authority in a single managing member.
Distributions
Equity holders have the right to share in profits. In a corporation these are dividends, declared at the board’s discretion. There’s no automatic right to a dividend just because the company is profitable. In LLCs and partnerships, profit distributions follow the allocation formula in the operating or partnership agreement and typically flow more directly to owners. Preferred holders in any structure often have distribution rights that kick in before common holders receive anything, especially during a sale or dissolution.
Information and Inspection Rights
Equity holders generally have the right to inspect the company’s financial books, meeting minutes, and ownership records. Most states require the request to be in writing and made for a legitimate purpose tied to the person’s interest as an owner. This right matters most in private companies where financial information isn’t publicly available. Without it, minority owners would have no way to verify that the business is being run properly or that their share of profits is being calculated correctly.
Protection From Dilution
When a company issues new equity, existing owners face dilution. Their percentage stake shrinks even though they haven’t sold anything. Preemptive rights protect against this by giving current owners the first opportunity to buy enough new shares or units to keep their proportional ownership. A 10% owner could purchase 10% of any new issuance. Preemptive rights aren’t automatic. They’re typically granted in the corporate charter or operating agreement and show up most often in private company deals.
Fiduciary Protections
Controlling shareholders, majority owners, and managing members owe fiduciary duties to minority owners. Courts have consistently held that those in control cannot use their position to benefit themselves at the expense of other owners. No self-dealing, no siphoning of company assets, no decisions engineered to squeeze out minority holders. Breaching these duties can expose controlling owners to personal liability in a lawsuit brought by the minority.
Limited Liability
Shareholders in corporations and members of LLCs benefit from limited liability. Their personal assets are shielded from the company’s debts and legal obligations, and their losses are generally capped at what they invested. General partners are the notable exception. They accept unlimited personal liability for partnership debts, which is one reason limited partnerships and LLCs have largely replaced general partnerships for most ventures.
How Equity Gets Valued
For publicly traded stock, value is straightforward. It’s whatever the shares trade for on the open market. Private equity interests are a different story entirely, and valuation is where most disputes between co-owners begin.
Book Value
The simplest approach calculates equity as total assets minus total liabilities on the balance sheet. That gives an accounting snapshot, but it tends to understate healthy businesses because it ignores brand, customer relationships, intellectual property, and future growth. Book value works best for asset-heavy businesses such as real estate holding companies, where the balance sheet closely tracks economic reality.
Discounted Cash Flow
The discounted cash flow method projects future earnings and discounts them back to a present value using a rate that reflects the riskiness of achieving them. A stable, profitable company gets a lower discount rate, and therefore a higher valuation, than a pre-revenue startup with unproven technology. It’s the most widely used approach for private companies, but it’s only as reliable as the assumptions behind it. Small changes in growth rates or discount rates can swing the result by millions.
Discounts for Private and Minority Interests
Even once a business’s overall value is set, a specific owner’s stake may be worth less than a proportional slice, for two reasons. Private company equity can’t be sold on an exchange with a click, so there’s a discount for lack of marketability, commonly 30% to 50% of the interest’s proportional value. And a minority owner who can’t control management decisions or force a sale holds a less valuable position than a controlling owner, so minority interest discounts often fall in the range of 15% to 40%. These discounts are standard in formal valuations for tax purposes, divorce proceedings, and buyouts. Professional business valuations typically run from a few thousand dollars for a simple company into six figures for complex enterprises.
How Equity Is Acquired and Transferred
Equity comes into existence and changes hands in a few different ways, and each carries its own legal and tax consequences.
Contributions and Sweat Equity
The most straightforward path is a capital contribution. You invest cash or property and receive an ownership stake in return. A second common route is sweat equity, where ownership is granted in exchange for services. Startup founders routinely divide equity among themselves based on the work each person commits to building the company. Sweat equity is almost always subject to a vesting schedule. Ownership accrues over time, and unvested shares revert to the company if the person leaves early.
You can also buy equity from an existing owner through a purchase agreement. This kind of secondary transaction is common in private companies when a founder, early investor, or departing partner wants to cash out.
Convertible Notes and SAFEs
Early-stage companies frequently raise money through instruments that aren’t equity yet but convert into equity later. A convertible note is a loan that converts into stock when the company raises its next round of funding, typically at a discount to the price new investors pay. It accrues interest and has a maturity date. A SAFE, or Simple Agreement for Future Equity, is simpler: the investor gives money now in exchange for the right to receive shares at a future triggering event, usually the next priced funding round. SAFEs carry no interest and no maturity. Both instruments defer the question of how much the company is worth until later, which is the entire point. Early-stage companies and their investors often can’t agree on a valuation, and these instruments let both sides move forward without settling it immediately.
Transfer Restrictions
Publicly traded stock can be sold to anyone at any time. Private company equity works differently. Operating agreements and shareholder agreements almost always contain restrictions designed to keep ownership in friendly hands.
The most common is a right of first refusal, which requires a selling owner to offer the interest to the company or existing owners before selling to an outsider. Existing owners get to match whatever deal the outside buyer offered. If they pass, the sale to the third party can proceed.
Buy-sell agreements go further by creating mandatory purchase obligations triggered by specific events such as death, disability, divorce, or retirement. These usually include a predetermined valuation method so there’s no fight over price when the trigger event happens. Companies that skip this step almost always regret it when a co-owner dies and the estate shows up expecting a buyout at a number nobody agreed to.
Vesting schedules apply to equity granted as compensation. A typical four-year schedule with a one-year cliff means the recipient earns nothing for the first twelve months, then 25% vests at the one-year mark, with the remainder vesting monthly or quarterly over the next three years. Unvested equity returns to the company automatically if the person leaves.
Tax Consequences of Owning Equity
The tax side of equity ownership is one of the most overlooked parts of the picture, and it changes dramatically depending on the entity and how you got your stake.
Pass-Through Versus Double Taxation
LLCs and partnerships are pass-through entities. The business itself doesn’t pay income tax. Each owner reports their share of the company’s income, deductions, and credits on a personal return, regardless of whether any cash was actually distributed.3Internal Revenue Service. Partnerships The company sends each owner a Schedule K-1 showing the allocated share.5Internal Revenue Service. Partners Instructions for Schedule K-1 (Form 1065) (2025) This catches new owners off guard: you can owe tax on income the company earned even if the company kept the cash and distributed nothing to you.
C corporations face double taxation. The corporation pays tax on its profits at the corporate rate, and shareholders pay again when those profits come out as dividends.6Internal Revenue Service. Forming a Corporation The corporation gets no deduction for paying dividends. S corporations avoid this by electing pass-through treatment, but they come with restrictions on the number and type of shareholders.
Selling and Capital Gains
When you sell an equity interest for more than your basis (generally what you paid for it), the profit is a capital gain. Hold the interest more than a year and the gain qualifies for long-term capital gains rates, which top out at 20% for the highest earners. Short-term gains on interests held a year or less are taxed as ordinary income, which can be nearly double the long-term rate. Timing matters.
Equity Compensation and the 83(b) Election
If you receive equity as compensation for work, such as restricted stock or stock options, tax treatment depends on the type of award. For nonstatutory stock options, you owe ordinary income tax on the difference between the market value and the price you paid when you exercise.7Internal Revenue Service. Topic No. 427, Stock Options Statutory stock options, including incentive stock options, generally aren’t taxed at exercise but may trigger alternative minimum tax obligations.
For restricted stock that vests over time, federal law gives you a critical choice. You can file an 83(b) election within 30 days of receiving the stock to pay tax on its current value immediately.8Office of the Law Revision Counsel. 26 USC 83 – Property Transferred in Connection With Performance of Services If the stock appreciates significantly before it vests, you’ll have locked in taxes at the lower early value, and all future appreciation gets taxed at long-term capital gains rates instead of ordinary income rates. Miss the 30-day window and the election is gone permanently. No extensions, no exceptions. For early-stage startup employees receiving stock worth very little at grant, filing the 83(b) is one of the highest-leverage tax moves available.
Qualified Small Business Stock
Founders and early investors in C corporations may qualify for a powerful tax break under the qualified small business stock rules. If the stock was acquired at original issuance from a qualifying domestic C corporation, the company’s gross assets didn’t exceed $50 million at the time, and you hold the stock for at least five years, you can exclude 100% of the capital gain on sale, up to $10 million or ten times your cost basis, whichever is greater.9U.S. Department of the Treasury. Quantifying the 100% Exclusion of Capital Gains on Small Business Stock The company must also use at least 80% of its assets in an active qualified business. Certain service-based industries don’t qualify, including health, law, engineering, accounting, financial services, consulting, and performing arts.
