An LLC does not have shares. Its owners hold what the law calls “membership interests,” and when those interests are divided into countable pieces, the pieces are called “units.” So the honest answer to whether an LLC has shares or units is: units, sometimes, and only because the operating agreement says so. Everything about how those units behave, what they’re worth, who can vote, and who gets paid comes from a private contract among the members, not from the corporate statutes that govern stock.
That distinction sounds like vocabulary, but it drives almost every practical difference between owning part of an LLC and owning part of a corporation.
What a Membership Interest Actually Is
A membership interest is the full bundle of what an LLC owner holds. It covers the economic claim on profits and assets, the right to vote on company decisions, and the obligations that come with being a member. Some LLCs break that interest into units, similar in spirit to shares. Others skip units entirely and simply record each member’s ownership as a percentage in the operating agreement. Both approaches are valid, and both produce the same underlying thing: a membership interest.
“Shares” and “stock” belong to the corporate world. A corporation issues stock under state corporate statutes, with rights that are largely standardized and a regulatory framework built around public trading. LLC units get their characteristics from whatever the members write down. A 10% unit in one LLC might carry full voting rights, a preferred return, and a management seat. A 10% unit in a different LLC might carry no vote at all and a subordinated claim on distributions. The operating agreement decides.
Units or Percentages
Whether an LLC uses units or straight percentages is a drafting choice. Units make it easier to bring in new members, create different classes of ownership, and grant equity to employees, because you can issue additional units without recalculating everyone’s percentage every time. Percentages are simpler for small LLCs with a fixed group of owners who don’t expect to add anyone. Neither approach changes the legal nature of what’s owned.
Why the Difference Between Shares and Units Matters
Every membership unit carries two separate bundles of rights, and an LLC can hand them out independently. That single feature is where most of the practical flexibility comes from.
Economic rights entitle the holder to allocations of profit and loss and to cash distributions. Those allocations flow through to each member’s individual tax return on a Schedule K-1.1Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) (2025) The split does not have to match ownership percentages. A member holding 30% of the units can receive 50% of the profits if the operating agreement says so.
Governance rights give the holder a say in decisions: approving major transactions, admitting new members, electing managers, amending the operating agreement. In a corporation, one share usually equals one vote. In an LLC, voting can be allocated almost any way the members choose, and voting and non-voting classes are common.2NCH. Can an LLC Issue Stock or Have Shareholders?
A founder who wants outside capital without giving up control can issue units that carry a share of profits but no vote. A corporation trying to accomplish the same result has to create separate stock classes with formal board and shareholder approvals under state corporate law, a much more rigid process.
Capital Accounts
Each member has a capital account that tracks the economic value of their stake. It starts with the initial contribution, increases with allocated profits and any additional contributions, and decreases with allocated losses and distributions. Capital accounts determine what each member receives if the LLC liquidates, and they form the backbone of the IRS rules that decide whether the profit and loss allocations in the operating agreement will hold up.3eCFR. 26 CFR 1.704-1 – Partner’s Distributive Share
Capital Interests and Profits Interests
Not every unit represents the same kind of ownership. The two main flavors are capital interests and profits interests, and they get taxed very differently at the moment they’re granted.
A capital interest gives the holder a claim on the LLC’s existing value. If the LLC liquidated the day after the interest was granted, the holder would receive a proportionate share of what the entity is worth right now. Members who buy in with cash or contribute property typically receive a capital interest, and their tax basis equals what they contributed.
A profits interest gives the holder a claim only on future profits and appreciation, not on the LLC’s current value. These are commonly used to compensate key employees, managers, and service providers who aren’t in a position to write a check. The IRS will not treat the receipt of a profits interest as a taxable event, provided the interest does not relate to a substantially certain income stream from partnership assets, the recipient does not dispose of it within two years, and the interest is not in a publicly traded partnership.4Internal Revenue Service. Rev. Proc. 2001-43
Compare that with a corporation. Granting someone stock in a corporation for services generally triggers immediate income tax on the fair market value of that stock. Granting a profits interest in an LLC can be tax-free at grant because it has no liquidation value on day one. The recipient pays tax only later, as the LLC actually earns profits allocated to their interest. For startups and growing businesses, this is one of the strongest arguments for using an LLC.
The Operating Agreement Sets the Rules
The operating agreement is the LLC’s constitution. It defines how many units exist, what rights attach to each class, how profits and losses are allocated, who votes on what, and how units can be transferred. Almost every choice described in this article is a choice the members make in that one document.
Without a written operating agreement, the LLC falls back on the default rules of the state where it was formed, and those defaults tend to be blunt. Most state LLC acts split profits in proportion to capital contributions and give every member an equal vote regardless of investment size. A member who put in 5% of the capital would get the same management vote as one who put in 80%. Business relationships that rely on state defaults tend to end in lawsuits.
Well-drafted agreements also cover capital calls. If the LLC needs additional money, the agreement authorizes managers to demand it and spells out the consequences for members who refuse: dilution, forced sale of the interest at a discount, forfeiture, or loss of voting and distribution rights until the shortfall is cured. If the operating agreement is silent, most state default rules give the LLC no way to force contributions at all.
How LLC Units Are Taxed
The default federal tax treatment depends on how many members the LLC has. A single-member LLC is treated as a “disregarded entity,” meaning the IRS ignores the LLC’s existence for income tax purposes and the owner reports all business income and expenses on Schedule C of their personal return.5Internal Revenue Service. Single Member Limited Liability Companies A multi-member LLC is taxed as a partnership by default, filing Form 1065 and issuing each member a Schedule K-1 with their share of income, losses, deductions, and credits.6Internal Revenue Service. Instructions for Form 1065 (2025)
Either way, the LLC itself pays no federal income tax. Income passes through to the members, who pay at their individual rates. That avoids the double taxation that C-corporations face, where the corporation pays tax on profits and shareholders pay tax again on the dividends.
An LLC can opt out of these defaults by filing Form 8832 to elect C-corporation treatment, or Form 2553 to elect S-corporation status. The election can take effect no more than 75 days before or 12 months after the filing date.7Internal Revenue Service. Form 8832 – Entity Classification Election These elections change the tax treatment, not the legal structure. The entity still has units and an operating agreement even if the IRS treats it like a corporation, and the K-1 may start using “shareholder” language. That’s a tax convention, not a change in what the members own.
Allocation Flexibility Compared With S-Corps
S-corporations must allocate income strictly in proportion to share ownership. LLCs taxed as partnerships can allocate profits and losses in any ratio the members agree to, provided the allocations have “substantial economic effect.” That means the operating agreement must maintain proper capital accounts, distribute liquidation proceeds according to capital account balances, and require members with negative capital account balances to restore the deficit.3eCFR. 26 CFR 1.704-1 – Partner’s Distributive Share This is why the S-corp election is often a poor fit for LLCs with complicated ownership arrangements: the election strips away the flexibility that made the LLC attractive in the first place.
Basis in LLC Units
A member’s tax basis in their units starts with the capital contribution, increases with the member’s share of income and of the LLC’s liabilities, and decreases with losses and distributions. Basis matters because losses are only deductible up to basis, and it determines whether a distribution triggers taxable gain.1Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) (2025) One advantage over corporate stock: LLC members include their share of the entity’s liabilities in their basis, which can meaningfully increase the losses they can deduct.
Selling or Transferring LLC Units
Transferring LLC units is nothing like selling stock through a brokerage. Nearly every operating agreement restricts transfers, because members choose their co-owners deliberately and an unrestricted sale could stick the group with an unwanted partner.
The most common restriction is a right of first refusal: a selling member must offer the units to the LLC or the other members at the same price before selling to an outsider. Many agreements also require the written consent of some or all of the remaining members before any transfer becomes effective. The paperwork is typically called an assignment of membership interest agreement, and the transfer isn’t complete until the LLC’s records are updated.8U.S. Securities and Exchange Commission. Form of Assignment and Assumption of Membership Interests
Economic-Only Transfers
There’s a useful middle ground. A member can often transfer just the economic interest, giving the buyer the right to receive distributions and tax allocations without the voting and governance rights. The buyer becomes an “assignee” rather than a full member. Operating agreements usually make economic-only transfers easier, sometimes requiring no consent at all, because the remaining members keep full control of the business.
Involuntary Transfers and Charging Orders
Not every transfer is voluntary. Operating agreements and buy-sell agreements typically list triggering events such as bankruptcy, divorce, and death, and they give the LLC or the other members a right to buy the departing member’s interest at a formula price. That prevents the interest from landing with a creditor, an ex-spouse, or an heir with no interest in running the business.
If a member’s personal creditor obtains a judgment, the creditor’s remedy against the LLC interest is generally limited to a charging order. A charging order is a court-ordered lien entitling the creditor to receive whatever distributions the LLC would have paid the debtor-member, but the creditor doesn’t become a member, doesn’t vote, and can’t force the LLC to distribute anything. In most states the charging order is the exclusive remedy available to a judgment creditor, and this protection is one reason people choose the LLC structure over holding assets individually or through a general partnership.
When LLC Units Count as Securities
LLC membership interests can qualify as “securities” under federal law, which triggers registration requirements and real penalties for missing them. The test comes from the Supreme Court’s decision in SEC v. W.J. Howey Co., which defines an investment contract as a transaction where someone invests money in a common enterprise, expects profits, and those profits come primarily from the efforts of others.
The key factor for LLCs is active participation. If the operating agreement gives a member real authority to make business decisions, the interest is less likely to be treated as a security. If the member is passive and depends entirely on managers to generate returns, the interest looks a lot like a securities investment. An LLC selling units to passive investors without a registration exemption faces potential enforcement action from the SEC and state regulators.
Most private LLCs avoid registration by relying on Regulation D. Rule 506(b) allows sales to an unlimited number of accredited investors and up to 35 non-accredited investors in any 90-day period, with no general solicitation or advertising. Rule 506(c) permits general solicitation but restricts sales to accredited investors whose status the LLC must take reasonable steps to verify.9U.S. Securities and Exchange Commission. Exempt Offerings An individual qualifies as accredited with income over $200,000 (or $300,000 with a spouse) in each of the prior two years, or net worth over $1 million excluding a primary residence.10U.S. Securities and Exchange Commission. Accredited Investors Even when an exemption applies, the LLC generally must file a Form D notice with the SEC within 15 days of the first sale.
Converting LLC Units to Corporate Shares
The moment LLC units actually become shares is when the LLC converts to a corporation, usually to prepare for venture capital funding or a public offering. In that conversion, membership units are exchanged for shares of corporate stock. Under IRC Section 351, the exchange is generally tax-free as long as the members transferring their interests collectively control at least 80% of the new corporation’s stock immediately after the conversion.11Office of the Law Revision Counsel. 26 USC 351 – Transfer to Corporation Controlled by Transferor
The conversion replaces the operating agreement with corporate bylaws and a certificate of incorporation. The flexible allocation and voting structures that made the LLC attractive disappear. Members who held disproportionate profit allocations or special voting rights need those arrangements translated into equivalent corporate stock classes before the conversion, or they lose them. Planned in advance, the process works smoothly. Left until the last minute, with an operating agreement that doesn’t address conversion mechanics and members disagreeing on how to value their different unit classes, it gets messy fast.
