An LLC can own shares in a C corporation, and there is no limit on the size of the stake. The LLC can hold one share or one hundred percent of the company, and it can be a single-member LLC, a multi-member LLC, or an LLC taxed as a corporation. What actually matters is not whether the ownership is allowed but how the LLC is classified for federal tax purposes, how the purchase is documented, and how carefully the two entities are kept separate afterward. Get those three things right and the structure works; get them wrong and you inherit tax problems, liability exposure, or both.
Why C Corps Allow LLC Owners When S Corps Don’t
The distinction comes from the Internal Revenue Code. An S corporation cannot have any shareholder that is not an individual, an estate, or one of a few specific types of trusts.1Office of the Law Revision Counsel. 26 U.S. Code 1361 – S Corporation Defined An LLC is not an individual, no matter how it’s taxed, so LLCs are locked out of S corporation ownership entirely.
C corporations carry no such restriction. Any person or entity that can enter a contract and hold property can own C corporation stock, including single-member and multi-member LLCs, other corporations, partnerships, trusts, and foreign entities. That openness is why holding-company structures almost always pair an LLC parent with a C corporation subsidiary rather than an S corporation subsidiary.
The LLC’s Tax Classification Drives Everything Else
Before the LLC buys a single share, decide how it is taxed. An LLC has no tax category of its own by default. The IRS applies check-the-box rules that assign a default classification based on the number of owners, and the LLC can override that default by filing Form 8832.2Internal Revenue Service. LLC Filing as a Corporation or Partnership
Three classifications are possible, and each creates a different tax outcome for dividends coming out of the C corporation.
A single-member LLC is a disregarded entity by default. The IRS ignores it for income tax purposes, and dividends from the C corporation land directly on the member’s personal return as if the member owned the shares individually.
A multi-member LLC is a partnership by default. It files Form 1065 and issues a Schedule K-1 to each member reporting that member’s share of dividend income. The LLC pays no entity-level tax.
Any LLC can file Form 8832 and elect corporate treatment. It then files its own Form 1120 and pays corporate income tax on dividends it receives, though it may qualify for the dividends received deduction described below.
Most LLCs that serve as holding companies for C corporation stock keep the default pass-through classification so dividends reach the individual owners without another layer of entity-level tax. But that isn’t automatic. Relying on the default when a different classification would be better, or electing corporate treatment without understanding what follows, produces tax bills that are hard to unwind.
How Dividends Get Taxed Under Each Classification
The C corporation pays federal income tax at a flat 21% rate on its profits before any dividends go out. What happens next depends on how the LLC is taxed.
Pass-Through LLCs
When the LLC is a partnership or disregarded entity, dividends pass through to the individual members. Those dividends are generally treated as qualified dividends and taxed at preferential capital gains rates of 0%, 15%, or 20% depending on the member’s taxable income.3Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions This is the classic double taxation of C corporation income: 21% at the corporate level, then up to 20% again at the individual level. High-income members may also owe the 3.8% net investment income tax on top.
LLCs Taxed as Corporations
An LLC that has elected corporate treatment receives dividends as a corporate shareholder and may claim the dividends received deduction. How much it can deduct scales with how much of the C corporation it owns:
- Less than 20% ownership: 50% of dividends received are deductible.
- 20% to 79% ownership: 65% of dividends received are deductible.
- 80% or more ownership (affiliated group): 100% of qualifying dividends are deductible.4Office of the Law Revision Counsel. 26 U.S. Code 243 – Dividends Received by Corporations
The 100% deduction at the 80% threshold effectively eliminates entity-level tax on dividends moving between the two companies. The individual owners of the LLC still face tax when the LLC distributes those funds to them, so double taxation shifts rather than disappears.
Consolidated Returns at 80% Ownership
An LLC taxed as a corporation that owns 80% or more of a C corporation may be eligible to file a consolidated federal tax return with the subsidiary. The rules require the common parent to be a corporation for federal tax purposes, and every member of the group must consent.5eCFR. 26 CFR 1.1502-75 – Filing of Consolidated Returns An LLC that is a partnership or disregarded entity cannot file a consolidated return with a C corporation subsidiary because it isn’t a corporation for tax purposes. Consolidation is one of the few situations where electing corporate treatment for the LLC unlocks a real planning advantage, since intercompany transactions get eliminated on the consolidated return.
Liability Separation and What Breaks It
Each entity keeps its own legal identity. The C corporation’s debts and lawsuits don’t automatically become the LLC’s problem, and that separation is usually the whole point of the arrangement.
The protection only holds when both entities are actually run as separate businesses. Courts will disregard the corporate veil and hold the parent LLC responsible for the subsidiary’s obligations when the two look interchangeable. The recurring factors:
- Commingling funds: shared bank accounts, one entity paying the other’s bills, money moving back and forth with no documented loans.
- Undercapitalization: leaving the subsidiary with so little funding that it can’t realistically meet its obligations.
- Ignored formalities: no board meetings, no separate books, no documentation of major decisions.
- No operational independence: no employees, no separate office, no real decision-making at the subsidiary.
Intercompany loans are where this most often falls apart. If the LLC lends money to its C corporation subsidiary, the loan needs a written agreement with a stated interest rate, a repayment schedule, and payments that actually happen on that schedule. An informal arrangement where the parent moves cash in whenever the subsidiary needs it reads as commingling to any court reviewing the relationship after a lawsuit.
Documenting the Share Purchase
The C corporation needs the LLC’s legal name as registered with the state, its principal business address, and its Employer Identification Number. If the corporation will pay dividends or other reportable income to the LLC, it should also collect a completed Form W-9. Without one on file, the corporation may have to withhold 24% of reportable payments as backup withholding.6Internal Revenue Service. Instructions for the Requester of Form W-9
The purchase itself gets papered through a stock purchase agreement or subscription agreement stating the number of shares, the price per share, and any conditions. Once signed, the C corporation’s secretary issues stock certificates in the LLC’s legal name and records the transaction in the corporate stock ledger. That ledger is the official record of who owns what, and it gets pulled during audits, financing rounds, and any ownership dispute.
Check the Bylaws Before Buying
Closely held C corporations often restrict share transfers in ways that can block or delay a purchase. Bylaws and shareholder agreements should be reviewed before the LLC commits:
- Right of first refusal: the corporation or existing shareholders get first crack at the shares at the proposed price.
- Board approval: some bylaws require directors to consent to any transfer, with discretion to deny transfers to competitors or to buyers who would push the shareholder count above SEC registration thresholds.
- Transfer volume rules: some bylaws prohibit partial transfers entirely.
Stock certificates in companies with these restrictions usually carry a printed legend warning any potential buyer. A transfer made in violation of these provisions may be void under the corporation’s governing documents, not merely disputed.
Securities Law: Is the LLC an Accredited Investor?
Every sale of stock is a securities transaction, including a sale between related entities. The Securities Act of 1933 requires offers to sell securities to be registered with the SEC or to fit within an exemption. Most LLC purchases of C corporation shares rely on a private placement exemption under Regulation D.
Private placements often require the LLC to qualify as an accredited investor. An LLC meets that standard if it holds more than $5 million in investments and was not formed specifically to buy the securities being offered. Alternatively, an LLC qualifies if every one of its equity owners individually qualifies as an accredited investor.7U.S. Securities and Exchange Commission. Accredited Investors For a newly formed holding-company LLC with limited assets, the second path is usually the practical one.
Ongoing Filings That Keep Both Entities Alive
Beneficial Ownership Reporting
The Corporate Transparency Act originally required most corporations and LLCs to file beneficial ownership reports with the Financial Crimes Enforcement Network. That changed in March 2025, when FinCEN issued an interim final rule exempting all entities created in the United States from BOI reporting.8Financial Crimes Enforcement Network. Beneficial Ownership Information Reporting Only entities formed under foreign law and registered to do business in a U.S. state remain subject to the filing requirement.9Federal Register. Beneficial Ownership Information Reporting Requirement Revision and Deadline Extension
A domestic LLC owning shares in a domestic C corporation currently has no BOI filing to make, and entities that already filed do not need to update or correct those reports. The exemption is an interim rule, and FinCEN has indicated a final rule will follow, so the requirements could shift again. Checking FinCEN before assuming the exemption is permanent is worth doing.
State Annual Reports
Both entities have to stay in good standing in their states of formation and in any state where they’re registered to do business. Most states require an annual or biennial report with the secretary of state confirming current address, registered agent, and officers or managers. Filing fees vary. Missing the filing can lead to penalties, loss of good standing, or administrative dissolution, and an administratively dissolved LLC may lose the legal capacity to hold shares at all.
The mistake that wrecks otherwise well-designed structures is treating the two entities as interchangeable because the same people run both. From a legal and tax standpoint, the LLC and the C corporation are strangers who happen to have an ownership relationship. Every transaction between them should look like it was negotiated between unrelated parties, because that’s the standard a court or the IRS will hold it to.
