Can an LLC Own Another LLC? Parent and Subsidiary LLCs

Yes. An LLC can own another LLC, either all of it or a share of it alongside other owners. The company that owns is usually called the parent, and the company it owns is the subsidiary. The IRS says so plainly on its LLC page: an LLC's members may include individuals, corporations, other LLCs and foreign entities, and state LLC laws allow it.

What changes is the paperwork and the tax picture. A subsidiary is its own company, with its own formation filing, its own state fees, its own registered agent and, in most cases, its own EIN and bank account. How it is taxed depends on whether the parent owns all of it or only part.

Why one LLC owns another

The point is almost always separation. Each LLC is responsible for its own debts, so putting different assets or activities in different companies keeps a problem in one from reaching the others. The common reasons:

• Separating a risky operation. A landscaping company that starts doing tree removal can put the tree work in its own subsidiary, so a claim over a fallen limb stays with that company and does not reach the trucks and contracts of the main business.
• Holding real estate. Many property owners put each building in its own LLC, owned by one parent. A tenant lawsuit at one address then reaches that building's company, not every property in the portfolio.
• A holding company. Some owners form one LLC whose only job is to own the operating companies, collect their profits and hold the valuable assets. That setup is often called a holding company LLC.
• Several businesses under one owner. A parent with a bakery subsidiary and a catering subsidiary keeps the two apart for liability, banking and an eventual sale of either one.
• Buying into a company or partnering. An LLC can take a share of a joint venture with other investors, so the parent, not its owners personally, holds the stake.

Separate LLCs are not the only way to run several brands. One LLC can trade under several names with DBAs, which is cheaper but keeps every brand inside the same company and the same liability. The trade-off is laid out in DBA vs LLC.

The two structures and how each is taxed

For federal tax, an LLC has no category of its own. The IRS classification rules in Treasury Regulation 301.7701-3 give a domestic LLC a default treatment based on how many members it has, and the subsidiary's members are counted the same way whether they are people or companies.

The parent owns 100 percent

A subsidiary with one member, the parent, is by default disregarded as an entity separate from its owner. It files no income tax return of its own: its income and expenses are reported by the parent. The IRS's single-member LLC page says that when the owner is a corporation or partnership, the LLC is reported as a division of that owner. So if Harbor Holdings LLC has two members and files a partnership return, the income of its wholly owned Harbor Rentals LLC appears inside Harbor Holdings' return. If the parent is itself a single-member LLC owned by one person, both companies are disregarded and the income lands on that person's own return. The single-member basics are in single-member LLC.

Disregarded does not mean invisible. The same IRS page says a single-member LLC is a separate entity for employment tax and certain excise taxes, so a subsidiary with employees runs its own payroll under its own name and EIN.

The parent owns part, with other members

A subsidiary with two or more members, for example the parent holding 60 percent and two investors holding 20 percent each, is by default a partnership. It files its own information return, Form 1065, and gives each member, the parent included, a Schedule K-1 showing its share of the income. The parent then reports that share on its own return. How a multi-member LLC splits profits and votes is covered in multi-member LLC.

Either default can be changed: an LLC can file Form 8832 to be taxed as a corporation. One election is mostly closed to subsidiaries. The IRS says S corporation shareholders may be individuals, certain trusts and estates, and may not be partnerships or corporations, so a subsidiary owned by a parent taxed either way generally cannot be an S corporation. A CPA or tax preparer can confirm how a particular chain of ownership is treated.

How to set up a subsidiary LLC

Forming a subsidiary is forming an LLC, with the parent in the owner's seat. The general filing steps are in how to start an LLC; these are the points specific to a company owned by a company.

1. Confirm the parent LLC is in good standing. The parent will own and sign for the new company, so it should be active on its state's records and current on its reports.
2. Authorize the new company under the parent's operating agreement. Read the parent's operating agreement for who can approve forming or buying a company and what vote it takes. Record the decision in a written consent or resolution, signed by the members or managers the agreement requires, and keep it with the parent's records.
3. File the subsidiary's articles with its own registered agent. File the articles of organization (or certificate of formation) in the state where the subsidiary will be formed. Where the form asks for members, managers or an organizer, list the parent LLC by its exact legal name; an individual may still sign as the organizer if the state allows. Name a registered agent for the subsidiary, which can be the same agent the parent uses, and pay the state's fee.
4. Sign the subsidiary's operating agreement. The subsidiary needs its own agreement naming the parent as its member and saying who manages it. The parent signs through the person with authority to act for it, in the form "Harbor Holdings LLC, by Dana Ruiz, its Manager". What the agreement should cover is in do you need an operating agreement.
5. Get the subsidiary its own EIN. The application lists the subsidiary's members and a person as the responsible party. The next section explains why that person cannot be the parent.
6. Open its own bank account and books. Open the account in the subsidiary's exact legal name with its EIN, and keep its books apart from the parent's. Money moving between the two should be recorded as what it is: a capital contribution, a loan or a distribution.
7. Register it in other states where it operates. A subsidiary formed in one state that has an office, staff or property in another usually needs to register there as a foreign LLC. The parent's registration in that state does not cover it. The rules are in foreign LLC registration.
8. Keep up its own state filings. The subsidiary's report and fees run on its own dates. Missing them can cost it its good standing even while the parent is current.

The federal beneficial ownership information (BOI) report is not one of the steps. FinCEN's final rule, effective August 14, 2026, permanently exempts companies created in the United States, so a domestic parent and its domestic subsidiary file none.

The subsidiary's EIN: responsible party and Form SS-4

Every EIN application names a responsible party, and this is where a subsidiary differs from an ordinary LLC. The Form SS-4 instructions say the responsible party is the person who ultimately owns or controls the entity, and that, unless the applicant is a government entity, the responsible party must be an individual, not an entity. The parent LLC owns the subsidiary, but it cannot be listed there. The application names a person who controls the parent instead, usually its managing member or manager, with that person's Social Security number or ITIN. The parent appears as the subsidiary's member: on Form SS-4 the LLC line asks for the number of members, which for a wholly owned subsidiary is one.

Two more rules matter when a parent forms several companies at once. The IRS issues one EIN per responsible party per day, online, by fax or by mail, so the same managing member applying for three new property LLCs gets them on three different days. And not every application finishes online. When the online application cannot issue the number, it ends with a reference number instead of an EIN. One a subsidiary can easily hit is reference number 101, a name match against the IRS's national records, which happens easily when Harbor Rentals LLC sits next to Harbor Holdings LLC and a dozen other Harbor companies. Retrying online returns the same result; those applications go by fax or mail on Form SS-4, as explained on llc-ein.com.

The IRS's single-member page adds that a disregarded LLC with no employees and no excise tax liability does not need an EIN for federal tax purposes. In practice most subsidiaries get one anyway, because banks ask for it before opening an account in the company's name and some states require it.

Keeping the separation real

A parent and subsidiary protect each other only while they behave like separate companies. If they are run as one, a court can disregard the line between them, which lawyers call piercing the veil, and let a creditor of one reach the assets of the other. The habits that keep the line in place are plain ones:

• Separate accounts. Each company deposits its own income and pays its own bills. The parent does not pay the subsidiary's rent from its own account.
• Contracts in the right name. Leases, invoices, insurance and licenses name the company actually doing the work or owning the asset. Where one company uses the other's property, a written lease at a fair price records it.
• Enough capital. A subsidiary set up with no money and no insurance to take on a risky activity is the classic case courts look past.
• Its own records. Major decisions, such as taking a loan, are recorded and signed for the company that makes them.

One limit is worth knowing before you count on the structure. A lender or landlord dealing with a new subsidiary often asks the parent, or its owners personally, to guarantee the debt. A guarantee is a promise to pay, and it puts the guarantor's assets back behind that debt whatever the company structure says.

Series LLC vs parent and subsidiary

A series LLC reaches a similar result with one company. Instead of forming separate LLCs, the owner forms a single LLC whose operating agreement creates internal series, each with its own assets, members and business. Where the statute's conditions are met, the debts of one series can be enforced only against that series' assets. Delaware's statute, section 18-215 of its LLC Act, puts it that way: the debts of a series are enforceable against the assets of that series only, not against the company generally or any other series.

Only a minority of states have a series statute, including Delaware, Illinois and Texas, and the mechanics differ. In Illinois each series is created by filing a certificate of designation with the Secretary of State. In Texas the series language goes in the certificate of formation and the company agreement, and the Secretary of State notes it has no separate form for a series LLC. Every version depends on keeping separate records for each series.

A series LLC can mean fewer formation filings, but it is less tested: states without a series statute, banks and lenders do not always treat a series as its own company. Separate LLCs cost a filing and a report each, and every state, bank and court understands them, which is why many owners who want separation choose the parent and subsidiary route.

Each LLC pays its own state fees

A subsidiary is a full LLC for the state, so it pays its own formation fee and its own recurring fee, on top of the parent's. Here is what the ten most populous states charge for each LLC. A subsidiary that also registers as a foreign LLC in another state pays that state's registration fee as well.
