An LLC cannot issue shares of stock in the way a corporation can. Instead, an LLC issues membership interests, usually called “units,” that represent each owner’s claim on the company’s profits, losses, and assets. The rules for those units come from the operating agreement rather than from a standardized body of corporate stock law, which is both the LLC’s biggest advantage and the source of most of its complications.
Units Instead of Shares
A corporation divides ownership into shares governed by statute. Each share within a class carries uniform rights, and a stock certificate is the definitive proof of ownership. An LLC works differently. State LLC statutes define a limited liability company interest as a member’s share of profits and losses plus the right to receive distributions of company assets. That interest is contractual at its core: the operating agreement, not a certificate, controls what the owner actually gets.
This is why many business owners choose the LLC form. Corporate stock structure follows relatively rigid statutory rules, while LLC units can be tailored to each member. One member might receive units tied to a large cash contribution; another might receive units reflecting services or intellectual property brought to the business. The agreement spells out what each person’s units entitle them to.
What the Operating Agreement Controls
Because units are contractual, the operating agreement is where ownership actually lives. It records each member’s name, the number of units or percentage interest they hold, and the capital contribution they made. It ties those interests to specific rights: who votes on major decisions, who manages day-to-day operations, and how profits and losses flow to each member.
The agreement also sets the rules for issuing new units later. It typically specifies whether the company can create additional interests and under what conditions, such as approval from a majority or all existing members. It addresses how new units will be priced, often referencing fair market value or a formula agreed on in advance. Setting these rules early gives the company a predictable process for raising capital without surprising the existing owners.
Anti-Dilution Protections
When new units are issued, existing members’ ownership percentages shrink unless the agreement addresses dilution. Protections take several forms. Pro-rata participation rights give existing members the first opportunity to buy new units in proportion to their current holdings. Consent-based restrictions require member approval before any new units can be issued at all. Some agreements use weighted-average adjustments that automatically recalculate ownership percentages to soften the impact of a new issuance. Including at least one of these mechanisms is standard practice when an LLC has multiple members.
Multiple Classes of Units
An LLC can create multiple classes of units with different bundles of rights, similar to how a corporation can issue common and preferred stock. State LLC statutes broadly authorize this, and the operating agreement can establish classes with distinct voting rights, profit-sharing arrangements, and distribution priorities.
A common structure separates voting units from economic-only units. Founders or active managers hold units carrying full voting rights and management authority, while passive investors hold a separate class limited to receiving distributions. The company gets outside capital without giving up operational control.
Distribution priorities add another layer. The agreement can specify that one class receives its share of profits before another, a structure often called a distribution waterfall. In investor-backed LLCs, the preferred class typically receives a priority return (often in the range of 8 to 10 percent annually) on invested capital before any distributions flow to the common class. These arrangements must be spelled out in the operating agreement to be enforceable, and the priority structure is usually among the most heavily negotiated terms when outside investors are involved.
How LLC Units Transfer
LLC membership interests do not change hands as freely as corporate stock. Under most state LLC statutes, a member can assign the economic rights attached to their units, meaning the right to receive distributions and allocations, without needing anyone’s permission. The assignee does not automatically become a full member, though. Gaining management rights and voting power typically requires consent of the other members or compliance with whatever admission process the operating agreement establishes.
This two-tier system exists by design. It protects existing members from being forced into a business relationship with someone they did not choose, while still letting a departing member monetize their stake. The operating agreement can modify these defaults, but if it says nothing, the statutory default in most states limits an assignee to economic rights only.
Issuing Units to a New Member
Bringing a new member into an LLC follows a sequence. The new member makes the agreed-upon capital contribution, whether cash, property, or services. The existing members then approve the admission under whatever voting threshold the operating agreement requires.
Two documents usually follow. First, an amendment to the operating agreement reflecting the updated ownership percentages and the new member’s contribution. Second, a joinder agreement in which the new member agrees to be bound by all terms of the existing operating agreement. The joinder avoids rewriting the full agreement while making sure the newcomer carries the same obligations and restrictions as the original members.
After signing, the company updates its internal records, often called a unit ledger or capitalization table. Some companies issue a physical unit certificate as a symbolic confirmation of ownership, though this is not legally required in most states. An amendment with the state may be needed if the change affects information on the formation documents, though many states do not require reporting ownership changes.
Securities Law Applies to Unit Issuances
One easily overlooked piece: LLC units can qualify as “securities” under federal law. The test comes from SEC v. W.J. Howey Co.: an investment of money in a common enterprise where the investor expects profits primarily from the efforts of others. An interest held by a passive investor who plays no role in management almost always meets this test. Even interests held by active members can qualify depending on how the company is actually run.
If units are securities, issuing them without registration or an exemption violates federal law. Most LLCs rely on an exemption under Regulation D:
- Rule 504 allows offerings of up to $10 million in a 12-month period, available to most non-reporting companies.
- Rule 506(b) has no cap on the amount raised, but the company cannot use general solicitation or advertising. Up to 35 non-accredited investors may participate, and each must be financially sophisticated enough to evaluate the investment. There is no limit on the number of accredited investors.
- Rule 506(c) also has no dollar cap and permits general solicitation, but every purchaser must be an accredited investor, and the company must take reasonable steps to verify that status.
Offerings under Rule 506 are “covered securities” under the National Securities Markets Improvement Act, which preempts state registration. States can still require notice filings and collect fees. Rule 504 offerings do not get this preemption and may need to comply with individual state securities laws.
Failing to comply can expose the company and its managers to rescission claims from investors and enforcement actions from the SEC or state regulators. Any LLC planning to issue units to investors, especially passive ones, should treat the issuance as a potential securities offering and confirm that an exemption applies before accepting capital.
Tax Treatment When Units Are Granted for Services
When an LLC grants units in exchange for services rather than cash, the tax result depends on the type of interest.
Capital Interests
A capital interest gives the recipient an immediate claim on a share of existing assets. If the LLC liquidated the day after the grant, the recipient would receive a payout. Receiving a capital interest for services is a taxable event. The recipient owes income tax on the fair market value of the interest at the time of the grant (minus anything they paid for it), and the company can generally deduct the same amount as a compensation expense.
Profits Interests
A profits interest entitles the holder only to a share of future growth and has no value at the time of grant based on current assets. Under IRS Revenue Procedure 93-27, receiving a profits interest for services is generally not a taxable event for either the recipient or the company, provided three conditions are met: the interest is not tied to a substantially certain and predictable income stream, the recipient does not dispose of the interest within two years, and the interest is not in a publicly traded partnership.
Profits interests are a popular way to compensate key employees, managers, or advisors because they share future upside without triggering an immediate tax bill. Many operating agreements add vesting schedules for profits interests, requiring the recipient to stay with the company for a set period before the interest fully belongs to them.
The Section 83(b) Election
When units of any type are subject to vesting, the recipient has a choice. By default, the IRS taxes the interest when it vests, not when it is granted. If the company has grown between the grant date and the vesting date, the tax bill at vesting can be large. A Section 83(b) election tells the IRS to tax the interest at its grant-date value instead. For a profits interest worth zero at grant, that locks in a tax bill of zero.
The election must be filed with the IRS within 30 days of the transfer date. No extensions. If that deadline falls on a weekend or legal holiday, the filing is timely if postmarked by the next business day. A copy must also go to the company. Missing the 30-day window means the election is permanently lost and cannot be made later, even with IRS consent.
