Can an LLC Own Another LLC? Formation, Liability, and IRS Rules

Yes, an LLC can own another LLC. Because an LLC is a separate legal entity that can hold assets, sign contracts, and do business in its own name, it can also hold a membership interest in a second LLC. The resulting parent-subsidiary structure is one of the most common ways business owners separate risk between ventures. It is straightforward to set up and recognized in every state, but the tax treatment and the discipline required to keep the liability shield intact catch a lot of owners off guard.

Why Owners Stack LLCs This Way

The main reason is compartmentalized liability. Each subsidiary operates as its own legal entity with its own assets and obligations, so if one subsidiary is sued or runs into financial trouble, creditors can typically only reach that subsidiary’s assets. The parent and any sibling subsidiaries stay insulated. Real estate investors lean on this constantly, putting each property into its own LLC so a lawsuit tied to one building cannot threaten the others.

Operational separation is the second reason. Different subsidiaries can have different managers, different operating agreements, and different members. That makes it easier to sell one line of business, bring in an investor at a single location, or wind down a failing piece without unwinding the whole company.

How the IRS Treats a Subsidiary LLC

When a parent LLC owns 100 percent of a subsidiary LLC, the IRS treats the subsidiary as a “disregarded entity” by default. The subsidiary does not file its own federal income tax return. Its income, deductions, and credits roll up to the parent’s return as if it were a division of the parent rather than a separate company.1Internal Revenue Service. Single Member Limited Liability Companies That keeps federal filing simple, but it also means the subsidiary cannot be used to shift income into a lower bracket or defer tax on its earnings.

If the subsidiary has two or more members, it is classified as a partnership for federal tax purposes and files its own informational return on Form 1065.2Internal Revenue Service.

One detail trips people up: even a disregarded-entity subsidiary is still treated as a separate entity for employment tax and certain excise taxes.2Internal Revenue Service. Limited Liability Company (LLC) If the subsidiary has employees, it needs its own payroll tax accounts.

How to Form a Subsidiary LLC

Forming a subsidiary follows the same steps as forming any LLC. The difference is that the parent LLC is listed as the member instead of an individual.

  • File articles of organization with the state filing office, usually the Secretary of State. The articles list the parent LLC’s legal name and address as the initial member. Filing fees generally range from $35 to $500.
  • Draft an operating agreement for the subsidiary, even if the state does not require one. It should define how the subsidiary is managed, how profits and losses are allocated, and what authority the parent holds. This document is also your primary evidence that the subsidiary is a separate entity if a court is ever asked to look.4U.S. Small Business Administration. Basic Information About Operating Agreements
  • Obtain an EIN for the subsidiary from the IRS, even if it has no employees. Important wrinkle: the responsible party on the application must be an individual with a Social Security number or ITIN, not the parent LLC itself. The IRS does not allow entities to serve as the responsible party, with a narrow exception for government entities. In practice this is usually a manager or member of the parent who controls the subsidiary day to day.5Internal Revenue Service. Responsible Parties and Nominees
  • Open a separate bank account for the subsidiary from day one, using its own EIN and articles of organization.

The IRS limits you to one EIN application per responsible party per day, so if you are forming several subsidiaries at once, pace the filings.6Internal Revenue Service. Get an Employer Identification Number

Keeping the Liability Shield Intact

Setting up a subsidiary is easy. Keeping its protection intact over time is where owners trip. Courts can “pierce the veil” and hold the parent responsible for the subsidiary’s debts when the two are not genuinely operating as separate businesses. The factors that come up again and again:

  • Commingling funds. Paying the subsidiary’s bills from the parent’s account, or the reverse, is the fastest way to lose protection. Each entity needs its own accounts, and money should move between them only through documented, arm’s-length transactions like loans or management fees.
  • Inadequate capitalization. A subsidiary set up with essentially no funding of its own looks like a shell. It should hold enough capital to cover its reasonably foreseeable obligations.
  • Ignoring formalities. Each LLC needs its own operating agreement, its own contracts, and its own records. The parent should not routinely make decisions a subsidiary manager would normally make, like hiring and firing the subsidiary’s employees.
  • Holding the subsidiary out as part of the parent. Sharing the same office, phone number, email domain, and staff without any distinction between the entities signals to a court that the subsidiary has no independent existence.

None of this is hard. It just takes discipline, and the owners who run into trouble are usually the ones who treat the subsidiary’s bank account like a second wallet.

Series LLC as an Alternative

A series LLC is a single LLC that creates internal divisions, each with its own assets, liabilities, members, and purpose. When the statute is followed, the debts of one series cannot be enforced against the assets of another series or the parent entity.7Wolters Kluwer. The Series LLC: An Organizational Structure That Can Help Mitigate Risk You get compartmentalized liability without forming a separate LLC for each division.

The limit is geographic. Series LLCs are authorized in roughly 20 jurisdictions, including Delaware, Texas, Illinois, Nevada, and Wyoming.7Wolters Kluwer. The Series LLC: An Organizational Structure That Can Help Mitigate Risk Courts in states that do not authorize them have not consistently respected the internal liability shields when disputes cross state lines. If your business operates in multiple states, the parent-subsidiary model is the safer choice because its legal recognition is universal.

What Ongoing Compliance Looks Like

Every LLC in the structure, parent and subsidiary alike, has to maintain its own compliance. Most states require an annual or biennial report listing the entity’s principal address, registered agent, and managers or members, with a filing fee that varies by state. Missing the deadline brings late fees, loss of good standing, and eventually administrative dissolution, which strips the entity of its legal existence and the liability shield that came with it.

Each LLC also needs a registered agent in every state where it is authorized to do business. If a subsidiary operates outside its formation state, it will typically need to register as a foreign LLC there, with a separate application and fee. Skipping that step can mean fines, inability to enforce contracts in that state’s courts, and back taxes.

The administrative load scales with every entity you add. Two subsidiaries operating in three states can easily mean six annual reports, six registered agent appointments, and six filing fees a year. That recurring cost is worth weighing before deciding how many entities the business actually needs. For some owners, a single LLC with solid insurance accomplishes most of the same practical result at a fraction of the overhead.
