Yes, a C corporation can own an LLC. It can be the LLC’s only member or co-own the LLC alongside other individuals or entities, and the federal tax treatment turns almost entirely on which of those two setups you pick. Whichever route the income takes to reach the parent, it hits the flat 21% federal corporate rate once it lands on the C corp’s return.1govinfo. 26 U.S.C. 11 – Tax Imposed
How the C Corporation Becomes a Member
There are two paths in. The C corp can form a new LLC and be named as a member in the articles of organization, or it can buy an existing member’s interest. When the C corp forms a new LLC and contributes cash or property in exchange for its membership interest, the contribution is generally tax-free under federal law. Neither the C corp nor the LLC recognizes gain or loss on the transfer.2Office of the Law Revision Counsel. 26 U.S.C. 721 – Nonrecognition of Gain or Loss on Contribution
There is one exception worth flagging up front: if the C corp contributes services rather than property, the value of the membership interest it receives is taxable as compensation income. Businesses miss this more often than you’d expect.
When the C corp is buying into an existing LLC, the deal follows whatever the operating agreement requires. The purchase price becomes the C corp’s tax basis in the interest.
How the IRS Classifies the LLC
State law calls the entity an LLC. The IRS does not care. Federal tax classification depends on two things: how many members the LLC has, and whether anyone has filed an election to change the default treatment.3eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities
Single-Member LLC: Disregarded Entity
If the C corp is the sole owner, the IRS treats the LLC as a “disregarded entity” for income tax purposes. The LLC’s revenue, expenses, and deductions flow directly onto the C corporation’s Form 1120, as if the C corp had earned and spent them itself.4Internal Revenue Service. Instructions for Form 1120 The LLC files no separate income tax return.
Reporting is simpler this way, but the C corp still has to keep separate books for the LLC. That bookkeeping separation matters for preserving the liability shield even though the IRS lumps everything together.
Multi-Member LLC: Partnership
When the C corp owns the LLC with at least one other member, the default classification is a partnership.3eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities The LLC files Form 1065 as an information return but pays no federal income tax itself.5Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income Each member gets a Schedule K-1 for its share of income or loss, and the C corp reports its K-1 income on Form 1120. Cash distributions are a separate question; the tax attaches to the allocated share whether or not any money changed hands.
Electing Corporate Treatment
Either type of LLC can opt out of its default classification and elect to be taxed as a corporation by filing Form 8832.6Internal Revenue Service. About Form 8832, Entity Classification Election Once the election is in place, the LLC pays corporate income tax on its own earnings and files its own Form 1120. That adds a tax layer most owners want to avoid. It occasionally makes sense in joint ventures where the parties want a clean break in tax obligations.
How the C Corp Is Taxed on the LLC’s Income
Whatever path the income takes, it faces the 21% federal corporate rate at the C corp level.1govinfo. 26 U.S.C. 11 – Tax Imposed The mechanics differ, and the second layer of tax that comes with any C corp is still there in the background.
Disregarded LLC
Income from a single-member LLC lands straight on the parent’s Form 1120 and is taxed once at the corporate level. When the C corp later distributes profits to its individual shareholders, those dividends are taxed again. Qualified dividends are taxed at rates up to 20%, and higher-income shareholders may owe an additional 3.8% net investment income tax, taking the effective rate on that second layer as high as 23.8%.7Office of the Law Revision Counsel. 26 U.S.C. 1411 – Imposition of Tax This is the standard C corp double-tax problem; putting the operating business inside an LLC doesn’t fix it.
Partnership LLC
With a multi-member LLC treated as a partnership, the C corp includes its K-1 share of the LLC’s income on its Form 1120 in the year the LLC earns it. The 21% is owed even if the LLC keeps all the cash for reinvestment and distributes nothing. Owners expecting to defer tax until they see a distribution get caught by this.
Dividends Received Deduction When the LLC Is Taxed as a Corporation
If a multi-member LLC has elected corporate treatment, its profits are taxed at the LLC level. Distributions up to the C corp are then dividends. Without relief this stacks three tax layers: LLC, parent C corp, and individual shareholder. The dividends received deduction eases that by letting the C corp deduct a share of the dividend it receives from the LLC, and the percentage depends on how much of the LLC the C corp owns:8Office of the Law Revision Counsel. 26 U.S.C. 243 – Dividends Received by Corporations
- Less than 20% ownership: 50% deduction.
- 20% to less than 80% ownership: 65% deduction.
- 80% or more ownership, where the C corp and the LLC qualify as an affiliated group: generally 100%, which effectively removes the corporate-level tax on the intercompany payment. The affiliated group test requires the parent to own at least 80% of the subsidiary’s total voting power and value.9Office of the Law Revision Counsel. 26 U.S.C. 1504 – Definitions
Payroll Taxes: The Disregarded LLC Is Not Disregarded
Here is a wrinkle that trips up compliance teams. Even though the IRS ignores a single-member LLC for income tax, it treats that same LLC as a separate entity for employment taxes. If the LLC has employees, the LLC itself is responsible for reporting and paying payroll taxes under its own name and its own employer identification number.10Internal Revenue Service. Single Member Limited Liability Companies The parent’s EIN will not work.
The LLC needs its own EIN, its own payroll accounts, and its own employment tax filings. Running the LLC’s payroll through the parent C corp’s accounts creates a records problem that can produce penalties and blur the legal line between the two entities.
State Taxes Do Not Follow Federal Classification
Federal disregarded-entity treatment does not automatically apply at the state level. Many states impose their own taxes and fees on LLCs regardless of what the IRS does. Annual report fees, franchise taxes, and minimum tax obligations vary widely, and in some cases the state bill for maintaining the LLC can exceed the federal simplicity gained. Check each state where the LLC will be registered or operate before you finalize the structure.
Keeping the Liability Shield Intact
The reason to put a business line or a risky asset inside a subsidiary LLC is to keep the parent C corp’s other assets out of reach if things go wrong. The shield only holds if the two entities genuinely act like separate businesses. When they don’t, courts can disregard the separation and hold the C corp responsible for the LLC’s obligations.
What Piercing the Veil Looks Like
The factors are mundane: commingling funds between the two entities, skipping required board meetings, treating the LLC as an internal extension of the C corp rather than an independent operation, and starting the LLC with almost no capital so the parent covers every expense. An LLC that never had its own financial legs looks like a shell.
Formalities and the Operating Agreement
The parent C corp needs to keep its own governance current: regular board and shareholder meetings, minutes for major decisions (including the resolution authorizing the LLC investment), and separate bank accounts and financial records. Officers should not cross-sign contracts in the wrong entity’s name.
Every LLC in this structure should have a written operating agreement, even a single-member LLC owned entirely by the C corp. For a sole-member LLC, the agreement documents the capital contribution, management authority, and decision procedures. For a multi-member LLC, it needs to cover voting rights, profit and loss allocations, distribution timing, and exit procedures.
Insurance reinforces the separation. Putting both entities on a single policy can create cross-liability exposure. Distinct policies, or at minimum each entity listed as a named insured rather than merely an additional insured, is the safer approach.
Why C Corporations Use This Structure
Risk isolation is the usual driver. A C corp running multiple business lines can house each one in its own LLC, so a lawsuit or liability in one unit doesn’t reach the others. Real estate companies do this property by property. Construction firms sometimes wall off a high-risk trade like concrete work in its own LLC.
The second draw is operational flexibility. LLCs have no required board of directors, no mandatory annual meetings at the LLC level in most states, and an operating agreement that can be tailored without navigating corporate governance statutes. When the C corp is the sole member, the disregarded-entity treatment means the LLC works like an internal division for tax purposes while still providing a legal liability barrier between the parent and the subsidiary’s activities.
