An equity interest is an ownership stake in a business. Holding one gives you a claim on the company’s assets and profits after everyone the company owes has been paid, along with a set of rights that depend on how the business is organized. The upside is uncapped if the company grows; the downside is that your claim sits last in line if the business fails.
Equity Versus Debt
The clearest way to understand equity is to put it next to the other way money moves into a business. A lender hands the company cash and gets back a fixed amount plus interest on a set schedule. The lender’s return is capped, and tripling profits next year does nothing for them. An equity holder owns a piece of the company itself. There is no guaranteed return, no maturity date, and no contractual right to get the original investment back on any particular timeline. The payoff comes from what the company actually does.
The difference matters most when things go wrong. In a liquidation or bankruptcy, federal law establishes a strict payment order: secured creditors first, then unsecured creditors, then penalties and fines, then interest on those claims, and only after each category is paid in full does anything flow to equity holders.1Office of the Law Revision Counsel. 26 USC 726 – Distribution of Property of the Estate In practice, equity holders in a failed business frequently receive nothing. That is the risk side of ownership.
What Equity Looks Like by Business Type
An equity interest takes a different legal form depending on how the business is organized. The structure determines how standardized the stake is, how transferable it is, and how much of it can be customized by private agreement.
Corporations
In a corporation, equity is represented by 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 for economic protections like 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 significantly from one company to the next.
LLCs
Equity in a limited liability company is called a membership interest, and these interests are highly customizable.2Internal Revenue Service. Limited Liability Company (LLC) The operating agreement, a private contract among the members, controls how profits are split, who makes management decisions, and what happens when someone leaves. 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 contributing more cash upfront. That flexibility is a major reason many private businesses pick the LLC form. The tradeoff is that membership interests are harder to sell, because no two are alike and any buyer has to read the operating agreement to know what they are actually getting.
Partnerships
A partnership interest represents equity in a partnership, and each partner has a capital account that tracks contributions, withdrawals, and accumulated earnings. General partners run the business and accept personal liability for its debts. Limited partners are essentially passive investors whose exposure is capped at what they put in.3Internal Revenue Service. Partnerships The partnership agreement governs how profits, losses, and decision-making are divided. Partnership interests are difficult to transfer and usually require consent from the other partners.
What Rights Come With an Equity Interest
Owning equity is not just about receiving money. It carries a bundle of rights that vary by entity type and by what the governing documents say.
Voting and Control
Shareholders in a corporation 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 way equity holders influence how the company is run, even though day-to-day operations stay with the board and the officers it appoints. In an LLC, voting rights are whatever the operating agreement says. 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 the company’s profits. In a corporation these payments are called dividends and are declared at the board’s discretion. There is no automatic right to a dividend just because the company is profitable. In LLCs and partnerships, distributions follow the allocation formula in the operating or partnership agreement and typically flow more directly to owners. Preferred equity holders 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 related to the person’s interest as an owner. The right matters most in private companies, where financial information is not publicly available. Without it, a minority owner would have no way to verify that the company is being run properly or that their share of profits is being calculated correctly.
Preemptive Rights
When a company issues new equity, existing owners face dilution: their percentage stake shrinks even though they haven’t sold anything. Preemptive rights push back against this by giving current owners the first chance to buy enough new shares or units to keep their proportional ownership. A 10% owner, for example, could purchase 10% of any new issuance. Preemptive rights are not automatic. They have to be granted in the charter or operating agreement, and they are more common in private company deals than public ones.
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. That rules out self-dealing, siphoning assets, and squeeze-out tactics aimed at the minority. Breaching those duties can expose a controlling owner 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, so if the business fails their losses are generally capped at what they invested. General partners in a partnership are the main 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.
What an Equity Interest Is Worth
For publicly traded stock the answer is simple: value is whatever the shares trade for on the open market. Private equity interests are a different story, and valuation is where most disputes between co-owners start.
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 the real value of a healthy business because it ignores brand, customer relationships, intellectual property, and future growth. Book value works best for asset-heavy businesses like real estate holding companies, where the balance sheet closely reflects economic reality.
Discounted Cash Flow
Discounted cash flow projects what the business will earn in the future and discounts those expected cash flows back to a present value, using a rate that reflects how risky those flows are. A stable, profitable company gets a lower discount rate and a higher valuation than a pre-revenue startup with unproven technology. DCF is the most widely used method for valuing private companies, but it is only as reliable as the assumptions behind it. Small changes in growth or discount rates can swing the result by millions.
Discounts for Private Interests
Even once a business’s overall value is set, a specific owner’s interest can be worth less than their proportional share, for two reasons. First, private company equity cannot be sold on an exchange with a click. That illiquidity usually produces a discount for lack of marketability, commonly in the range of 30% to 50% of the proportional value. Second, a minority owner who cannot control management or force a sale holds a weaker position than a controlling owner. Minority interest discounts often fall between 15% and 40%. Both discounts are standard in formal valuations used for tax purposes, divorce proceedings, and buyouts.
How Equity Is Acquired and Transferred
Equity comes into existence and changes hands through a handful of mechanisms, each with its own legal and tax consequences.
Capital Contribution 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 route is sweat equity, where the company grants ownership in exchange for services. Startup founders routinely divide equity among themselves based on the work each person commits to building the business. Sweat equity is almost always subject to a vesting schedule, so ownership accrues over time and unvested shares revert to the company if the person leaves early.
Buying From an Existing Owner
You can also buy equity from someone who already owns it through a purchase agreement. These secondary transactions are common in private companies when a founder, early investor, or departing partner wants to cash out.
Convertible Instruments
Early-stage companies frequently raise money through instruments that are not equity yet but convert into it later. A convertible note is a loan that converts into stock when the company raises its next round, usually at a discount to the price new investors pay. It accrues interest and has a maturity date like any other debt. A SAFE, or Simple Agreement for Future Equity, is simpler: the investor pays now in exchange for the right to receive shares at a future triggering event, typically the next priced funding round. SAFEs carry no interest and no maturity date. Both instruments defer the question of what the company is worth, which is the entire point when founders and investors cannot yet agree on a valuation.
Transfer Restrictions
Publicly traded stock can be sold to anyone at any time. Private company equity usually cannot. 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 their interest to the company or existing owners before selling to an outsider. The existing owners can match whatever deal the outside buyer offered, and if they pass, the sale can proceed. Buy-sell agreements go further and create mandatory purchase obligations triggered by specific events like death, disability, divorce, or retirement. These typically include a predetermined valuation method so there is no fight over price when the triggering 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.
Taxes You Should Know About
Tax treatment of an equity interest varies by entity type and by how you got the stake, and some of the rules catch new owners by surprise.
LLCs and partnerships are pass-through entities. The business itself does not pay income tax. Each owner reports their share of the company’s income, deductions, and credits on their personal return, whether or not any cash was actually distributed.3Internal Revenue Service. Partnerships The company sends each owner a Schedule K-1 showing their allocated share.5Internal Revenue Service. Partners Instructions for Schedule K-1 (Form 1065) (2025) That means you can owe tax on income the company earned even if the company kept all 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 tax 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, though they come with restrictions on the number and type of shareholders.
Selling an equity interest for more than your basis produces a capital gain. If you held the interest for more than a year, the gain qualifies for long-term capital gains rates, which top out at 20% for the highest earners. Gains on interests held a year or less are taxed as ordinary income, which can be nearly double the long-term rate.
If you receive equity as compensation, the 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 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 will have locked in tax 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.
