Converting an LLC to a C Corporation is done by filing conversion, merger, or incorporation documents with your state and then notifying the IRS of the new tax classification. The paperwork is short. The tax consequences are not: structured correctly, the swap itself is tax-free under Section 351, but the corporation you end up with faces a 21% federal rate on its profits and a second layer of tax when it distributes them. Get the sequence and the numbers right and you also start the clock on the Section 1202 QSBS exclusion, which can wipe out federal capital gains tax on up to $15 million of eventual sale proceeds.
Pick a Conversion Method
Four legal paths exist. Which one you can use depends on your state’s statutes and how complex your LLC’s obligations are.
Statutory conversion is the cleanest where available. You file articles of conversion with the state and the LLC becomes a C Corporation as a continuation of the same entity. Assets, liabilities, and contracts carry over automatically, and no separate dissolution is needed in most states.
Statutory merger is the fallback where direct conversion isn’t offered. You form a new C Corporation, draft a merger agreement, get member approval, and file merger documents. The LLC dissolves by operation of law and the corporation inherits its assets and liabilities.
Asset transfer is the manual route: form a new corporation, transfer each asset and liability through individual assignments, then dissolve the LLC. It works in every state but is the most labor-intensive option and most likely to trigger consent requirements in existing contracts.
Contribution of interests for stock has the LLC members contribute their membership interests to a new corporation in exchange for shares. The LLC then dissolves or elects corporate tax treatment. This route can qualify as a tax-free exchange under Section 351 if the control test is met.
The method matters beyond paperwork. A statutory conversion that continues the same legal entity generally does not require a new EIN. A merger into a newly formed corporation or an asset transfer does, because a new entity has been created. A new EIN can be obtained online through the IRS at no cost, or by submitting Form SS-4.1Internal Revenue Service. Get an Employer Identification Number
Line Up Approvals and Consents First
Read your operating agreement before anything else. Most require unanimous or majority member approval for a conversion, and skipping the vote can invalidate the filing.
Then review every significant contract. Loan agreements, commercial leases, and vendor contracts often contain anti-assignment or change-of-control clauses that treat a conversion or merger as an assignment by operation of law. Violating one is a breach: the counterparty may terminate the agreement or accelerate a loan balance. Get written consents before you file anything with the state.
Get a fair market valuation of the LLC’s assets before the conversion. It determines the tax basis of the stock shareholders receive and the basis of assets inside the corporation, and it matters for Section 1202 eligibility, which caps aggregate gross assets at the time of issuance. Rough estimates create problems that surface years later.
Prepare the Corporate Documents
You will need articles of incorporation, corporate bylaws, and initial shareholder agreements if ownership will be split. The articles must include the corporate name, a registered agent with a physical address in the state, and the number and classes of authorized shares. Decide on your share structure before filing, particularly whether you will authorize only common stock or also preferred stock for future fundraising.
File With the State and Notify the IRS
Depending on the method, you file articles of conversion, articles of merger, or articles of incorporation with the Secretary of State. Most states accept online filings. State filing fees generally range from $25 to $200, though a few states charge more for corporations authorizing large numbers of shares.
Most states let you specify a future effective date, which is useful for aligning the conversion with a tax year or quarter.
A state-level statutory conversion does not automatically change your federal tax classification. File Form 8832, Entity Classification Election, to elect corporate treatment, which defaults to C Corporation status.2Internal Revenue Service. About Form 8832, Entity Classification Election The election cannot take effect more than 75 days before the filing date, and no more than 12 months after it.3Internal Revenue Service. IRS Form 8832 – Entity Classification Election Miss that 75-day window and the election defaults to the earliest permissible date, which may not be what you wanted.
If the conversion creates a new legal entity through merger or asset transfer, the new EIN filing and initial Form 1120 effectively establish classification, but filing Form 8832 is still worth doing to eliminate ambiguity.
After filing, update business licenses, professional permits, state tax registrations, bank accounts, merchant processing agreements, and insurance policies to reflect the new entity. Industry-specific licenses (liquor, contractor, healthcare) may not transfer automatically and may need to be reissued.
Tax Consequences of the Swap Itself
The conversion can usually be structured as a nontaxable event, but two traps turn a clean swap into a taxable one.
The Section 351 Control Test
Under Section 351, transferring property to a corporation in exchange for stock is a nonrecognition event, meaning no gain or loss is recognized at the time of transfer, if the transferors collectively own at least 80% of the corporation’s total voting power and at least 80% of all other classes of stock immediately after the exchange.4Office of the Law Revision Counsel. 26 U.S. Code 351 – Transfer to Corporation Controlled by Transferor In a typical LLC conversion where all members exchange interests for stock, the test is easy to meet. Problems appear when the conversion coincides with bringing in new investors who dilute original members below 80%, or when members receive cash or other non-stock consideration alongside their shares.
When Liabilities Exceed Basis
Section 357(c) creates a taxable event even inside a qualifying Section 351 transfer when the total liabilities transferred to the corporation exceed the total adjusted basis of the transferred assets. The excess is capital gain. This catches businesses that carry significant debt against low-basis assets, such as an LLC whose main asset is fully depreciated equipment while the original purchase loan is still outstanding. One important exception: liabilities whose payment would give rise to a tax deduction, like accounts payable for deductible expenses, are excluded from the calculation.5Office of the Law Revision Counsel. 26 U.S. Code 357 – Assumption of Liability
Tax Consequences Going Forward
Two Layers of Tax
The corporation pays federal income tax at a flat 21% rate on its taxable income.6Congressional Budget Office. Increase the Corporate Income Tax Rate by 1 Percentage Point When after-tax profits are distributed as dividends, shareholders pay tax again at their individual rate, typically 15% or 20% for qualified dividends. This is the fundamental tradeoff of C Corporation status, and it’s the reason businesses that don’t need outside capital often stay as LLCs.
Accounting Method
C Corporations with average annual gross receipts above a threshold (inflation-adjusted from a $25 million statutory base) generally cannot use the cash method and must switch to accrual.7Office of the Law Revision Counsel. 26 U.S. Code 448 – Limitation on Use of Cash Method of Accounting Smaller corporations under the threshold can keep using cash. If the conversion forces a change, file Form 3115.8Internal Revenue Service. About Form 3115, Application for Change in Accounting Method The resulting Section 481(a) adjustment to taxable income is typically spread over four tax years rather than hitting all at once.
Owner Compensation and Payroll
This is where new C Corporation owners often stumble. In an LLC taxed as a partnership, owners take draws and pay self-employment tax on their share of business income. In a C Corporation, the IRS treats corporate officers who perform services as employees.9Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers You set up payroll, withhold income tax, and split FICA between the corporation and the officer-employee.
There is an upside. As an LLC member you paid the full self-employment tax; as a corporate employee you pay only the employee half, and the corporation pays and deducts the other half. You cannot game this by taking a token salary and paying yourself the rest as dividends. The IRS requires compensation to be reasonable for the services performed, and courts weigh factors like the officer’s duties, time commitment, pay at comparable businesses, and the company’s dividend history. An unreasonably low salary invites reclassification of dividends as wages, plus back taxes and penalties.
Annual Filing
The corporation files Form 1120 annually to report income, deductions, and tax liability.10Internal Revenue Service. About Form 1120, U.S. Corporation Income Tax Return The due date is the 15th day of the fourth month after the fiscal year ends, so April 15 for calendar-year corporations. Late filing triggers a penalty of 5% of the unpaid tax per month, up to 25%. If the return is more than 60 days late, the minimum penalty is $525 or 100% of the unpaid tax, whichever is less.11Internal Revenue Service. Failure to File Penalty
The QSBS Payoff, and Its Limits
For founders who plan to sell, Section 1202 is often the strongest reason to convert. It lets non-corporate taxpayers exclude capital gains on stock held in a qualifying C Corporation.12Office of the Law Revision Counsel. 26 U.S. Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock
For stock acquired after July 4, 2025, the exclusion is tiered by holding period:
- 3 years: 50% of the gain excluded
- 4 years: 75% of the gain excluded
- 5 or more years: 100% of the gain excluded
The maximum any single taxpayer can exclude per issuing company is the greater of $15 million or ten times the adjusted basis of the stock. The $15 million cap will adjust for inflation starting in 2027.12Office of the Law Revision Counsel. 26 U.S. Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock
Qualifying takes work. The corporation’s aggregate gross assets cannot exceed $75 million at any point before or immediately after the stock issuance. The stock must be acquired at original issuance in exchange for money, property, or services, so secondary purchases don’t count. During substantially all of the holding period, at least 80% of the corporation’s assets by value must be used in an active qualified trade or business.12Office of the Law Revision Counsel. 26 U.S. Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock
Several service industries are excluded outright: health, law, engineering, architecture, accounting, consulting, financial services, performing arts, and athletics, among others. The common thread is businesses whose principal asset is the reputation or skill of one or more employees. If your LLC operates in one of these fields, QSBS won’t apply after conversion, which may change whether converting is worth the added tax and compliance load.
Timing matters. The holding period starts when the stock is issued, not when the LLC was originally formed. Converting sooner starts the clock sooner.
Corporate Formalities Protect the Shield
Hold annual meetings of shareholders and directors and keep written minutes. Maintain a stock ledger documenting every share issued, transferred, or cancelled. Record major decisions in formal resolutions. Courts look at exactly these records when deciding whether to pierce the corporate veil and hold shareholders personally liable for corporate debts. Commingling personal and business funds, undercapitalization, and skipping formalities are the factors that trigger personal liability. Sloppy records are the fastest way to lose the liability protection you converted to get.
Most states also require annual reports and franchise tax payments to keep the corporation in good standing. Falling behind can lead to administrative dissolution, which strips the corporation of its authority to do business in the state. Fees and deadlines vary, so check with the Secretary of State after the conversion.
Employee benefit plans, payroll accounts, and insurance policies need to be transitioned to the corporate entity. If the LLC maintained a retirement plan, the plan documents may need to be amended or replaced to reflect the new employer.
