To convert an LLC to a C Corporation, you choose a legal path your state allows — most often a statutory conversion, a statutory merger, an asset transfer, or a contribution of membership interests for stock — then file the required documents with the state, notify the IRS of the new tax classification, and update everything from payroll to bank accounts. The filings themselves are short. The tax and operational consequences underneath them are not, and the method you pick affects whether you need a new EIN, how your contracts travel, and whether the swap stays tax-free.
Pick a Conversion Method
Four routes exist. Availability depends on your state’s statutes and the complexity of what the LLC owns and owes.
Statutory Conversion
The cleanest option where it’s offered. You file articles of conversion (or the state’s equivalent form) and the LLC transforms directly into a C Corporation as a continuation of the same entity. Assets, liabilities, and contracts carry over automatically. No new entity is created, and most states don’t require a separate dissolution filing.
Statutory Merger
Where statutory conversion isn’t available, you form a new C Corporation and merge the LLC into it. You’ll draft a merger agreement, get member approval, and file merger documents with the state. The LLC dissolves by operation of law and the surviving corporation inherits its assets and liabilities.
Asset Transfer
The manual approach. Form a new C Corporation, then transfer each asset and liability through individual agreements, and dissolve the LLC afterward. Every contract, lease, bank account, and intellectual property registration needs its own assignment. It’s the most labor-intensive method and the most likely to trigger consent requirements in existing contracts, but it’s available in every state.
Contribution of Interests for Stock
Members contribute their membership interests to a new C Corporation in exchange for shares. The LLC then dissolves or elects corporate tax treatment. Structured correctly, this can qualify as a tax-free exchange under Section 351, but the control test discussed below has to be met.
Before You File
Internal Approvals and Contract Review
Start with the operating agreement. Most require unanimous or majority member approval for a conversion, and skipping the vote can invalidate the filing. While approvals are moving, review every significant contract the LLC holds. 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, and the counterparty may have the right to terminate the agreement or demand immediate repayment. Identify these contracts early and get written consent before you file anything with the state.
Corporate Documents
You’ll need articles of incorporation, corporate bylaws, and initial shareholder agreements if ownership will be split among multiple people. The articles of incorporation 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 share structure before filing, particularly whether to authorize only common stock or also preferred stock for future fundraising.
Employer Identification Number
Whether you need a new EIN depends on the method. 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 exists. You can apply online through the IRS at no cost and receive the number immediately, or submit Form SS-4 by fax or mail.1Internal Revenue Service. Get an Employer Identification Number
Asset Valuation
Get a fair market valuation of the LLC’s assets before the conversion. This sets the tax basis of the stock shareholders receive and the basis of assets inside the new corporation. It also matters for Section 1202 eligibility, because the corporation’s aggregate gross assets must stay below the statutory threshold at the time of issuance. Rough estimates create problems that surface years later when you sell the company or try to claim a tax exclusion.
Filing and Notifying the IRS
Once approvals are in hand and documents are ready, file the articles of conversion, articles of merger, or articles of incorporation (whichever your method requires) with the Secretary of State’s office. Most states accept online filings. Filing fees generally range from $25 to $200, though some states charge more for corporations authorizing large numbers of shares.
Choosing an Effective Date
Most states let you specify a future effective date, which is useful for timing the conversion to the start of a tax year or quarter. If you’re using Form 8832 to elect corporate tax classification, the IRS has its own rule: the election cannot take effect more than 75 days before the filing date, and no more than 12 months after it.2Internal Revenue Service. IRS Form 8832 – Entity Classification Election Miss the 75-day window and the election defaults to the earliest permissible date, which may not match what you wanted.
Telling the IRS
A state-level statutory conversion does not automatically change your federal tax classification. You separately notify the IRS by filing Form 8832, Entity Classification Election, to elect corporate treatment (which defaults to C Corporation status).3Internal Revenue Service. About Form 8832, Entity Classification Election If the conversion creates a new legal entity through merger or asset transfer, the new corporation’s EIN filing and initial Form 1120 effectively establish the classification, though filing Form 8832 is still worth doing to remove ambiguity.
Licenses and Accounts
Update business licenses, professional permits, and state tax registrations to reflect the new corporate entity. If the LLC held industry-specific licenses — liquor licenses, contractor permits, healthcare certifications — check whether those transfer automatically or need to be reissued. Bank accounts, merchant processing agreements, and insurance policies all need updating as well.
Tax Consequences at Conversion
The conversion itself can usually be structured as a nontaxable event. Several traps turn an otherwise clean swap into a taxable one.
Section 351 Control Test
Under Section 351, transferring property to a corporation in exchange for stock is a nonrecognition event (no gain or loss recognized at transfer) if the transferors collectively own at least 80% of the corporation’s total voting power and at least 80% of each other class 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 conversion where all LLC members exchange their interests for stock, this is easy to satisfy. The test gets harder when the conversion coincides with bringing in new investors who dilute the originals below 80%, or when members receive cash or other non-stock consideration alongside their shares.
When Liabilities Exceed Basis
Even where Section 351 otherwise applies, Section 357(c) creates a taxable event when the total liabilities transferred to the corporation exceed the total adjusted basis of the transferred assets. The excess is treated as capital gain. This catches businesses carrying significant debt against low-basis assets — think of an LLC whose main asset is fully depreciated equipment that still has the original purchase loan outstanding. One exception matters: liabilities whose payment would give rise to a tax deduction, such as accounts payable for deductible expenses, are excluded from the calculation.5Office of the Law Revision Counsel. 26 U.S. Code 357 – Assumption of Liability
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.6Office of the Law Revision Counsel. 26 U.S. Code 448 – Limitation on Use of Cash Method of Accounting Smaller C Corporations below the threshold can keep using cash. If the conversion forces a change, file Form 3115, Application for Change in Accounting Method.7Internal 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.
QSBS: Why Timing Matters
For founders planning to build and eventually sell, Section 1202’s Qualified Small Business Stock exclusion is often the strongest reason to convert. It lets non-corporate taxpayers exclude a substantial portion of capital gains when selling stock held in a qualifying C Corporation.8Office 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% excluded
- 5 or more years: 100% 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 2027.8Office of the Law Revision Counsel. 26 U.S. Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock
Qualifying is conditional. 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; secondary market 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.8Office of the Law Revision Counsel. 26 U.S. Code 1202 – Partial Exclusion for Gain From Certain Small Business Stock
Several service industries are excluded from QSBS entirely: 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 makes sense.
Timing matters because the holding period starts when the stock is issued, not when the LLC was originally formed. Converting sooner starts the clock sooner.
What Changes After Conversion
Owner Pay and Payroll
This is where many new C Corporation owners 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 That means running payroll, withholding income tax, and splitting FICA between the corporation and the officer-employee.
There is a silver lining. As an LLC member you paid the full self-employment tax; as a corporate employee you pay only the employee half, with the corporation paying and deducting the other half. You cannot game this by paying yourself a token salary and taking the rest as dividends. The IRS requires compensation to be reasonable for the services performed, measured against 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.
Double Taxation
Once the C Corporation exists, its profits face two layers of tax. The corporation pays federal income tax at a flat 21% rate on taxable income.10Congressional Budget Office. Increase the Corporate Income Tax Rate by 1 Percentage Point When after-tax profits are distributed as dividends, shareholders pay again at their individual rate, typically 15% or 20% for qualified dividends. This is the fundamental tradeoff of C Corporation status and the main reason companies that don’t need outside investment often stay as LLCs.
Federal Return
The C Corporation files Form 1120, U.S. Corporation Income Tax Return, annually.11Internal Revenue Service. About Form 1120, U.S. Corporation Income Tax Return It’s due the 15th day of the fourth month after the fiscal year ends (April 15 for calendar-year corporations). Late filing triggers a penalty of 5% of the unpaid tax per month, capped at 25%, with a minimum penalty if the return runs more than 60 days late.12Internal Revenue Service. Failure to File Penalty
State Reports and Franchise Tax
Most states require annual reports and franchise tax payments to keep the corporation in good standing. Falling behind can result in administrative dissolution, stripping the corporation of its authority to do business in the state. Fees and deadlines vary, so check with your state’s Secretary of State office after the conversion.
Corporate Formalities
Hold annual meetings of shareholders and the board, and keep written minutes. Maintain a stock ledger documenting every share issued, transferred, or cancelled. Record major decisions in formal resolutions. These are the evidence that the corporation operates as an entity separate from its owners. Courts look at exactly these records when deciding whether to pierce the corporate veil and hold shareholders personally liable for corporate debts. Sloppy records are the fastest way to lose the liability protection you converted to get.
Updating Contracts and Accounts
Notify banks to update account ownership, reissue business licenses in the corporation’s name, and review every vendor agreement and lease for assignment or name-change provisions. If you used the asset-transfer method, each contract technically needs a new agreement or novation. Even with a statutory conversion where the entity continues, counterparties appreciate written notice and some contracts require it. Employee benefit plans, payroll accounts, and insurance policies all need to be transitioned to the corporate entity, and any retirement plan documents may need amendment to reflect the new employer.
