LLC to C Corp Conversion: Statutory Filing and Section 351 Rules

An LLC to C Corp conversion is usually accomplished in one of three ways: a statutory conversion filed with the state, a statutory merger of the LLC into a newly formed corporation, or a transfer of the LLC’s assets to a new corporation followed by dissolution of the LLC. Statutory conversion is the cleanest and cheapest path where a state offers it. Whichever method you use, the transaction needs to qualify for tax-free treatment under Section 351 of the Internal Revenue Code, or you will owe federal tax the moment you file.

Which Conversion Method to Use

Most states have adopted conversion statutes, and where that is available, statutory conversion is the right default. The LLC changes its legal form to a corporation in a single filing. Contracts, liabilities, business history, and the federal EIN carry over automatically because it is the same entity in a new legal form.

A statutory merger is the right choice when you are also changing the state of domicile (say, a California LLC becoming a Delaware corporation) or when the ownership structure needs to change in ways a straight conversion cannot accommodate. You form a new corporation, then merge the LLC into it under a written merger agreement, with the corporation as the surviving entity. The LLC’s members approve the agreement, the corporation’s board approves it, and you file a Certificate or Articles of Merger. The corporation absorbs the LLC’s contracts, property, and liabilities by operation of law. More paperwork than a conversion, same end result.

The asset transfer and dissolution method is the fallback: form the corporation, transfer everything the LLC owns to it in exchange for stock, distribute that stock to the LLC’s members, then file Articles of Dissolution for the LLC. This was standard practice before conversion and merger statutes became common, and it still gets used when neither of the other methods is available. It is the most expensive route because you pay for separate transfer agreements covering each asset class, possible real estate transfer taxes and recording fees, and the dissolution filing itself. If the LLC owns real property, get a title review before choosing this path; some jurisdictions have no exemption from transfer tax for entity restructurings. And do not skip the dissolution filing. An LLC left on the books keeps accruing franchise taxes, annual report fees, and penalties for an entity that no longer does anything.

Filing a Statutory Conversion

The conversion starts with a Plan of Conversion. This is a written document that sets out how membership interests convert into shares of corporate stock, the effective date, and any conditions that must be met before filing. State law requires the LLC’s members to approve the plan by whatever vote the operating agreement specifies, or by the state’s default rule if the operating agreement is silent. Default rules range from simple majority to unanimous consent depending on the state.

Before drafting the plan, decide how many shares the corporation will authorize and at what par value. Early-stage companies commonly authorize between one million and ten million shares to leave room for future equity rounds and employee stock grants. Par value is usually set very low, often around $0.0001 per share. In most states par value carries little practical weight, but in a handful of jurisdictions it affects franchise taxes, so check before defaulting to a number.

Once the members approve the plan, you file two documents with the Secretary of State at the same time: a Certificate of Conversion (some states call it a Statement of Conversion) and Articles of Incorporation for the new corporation. Both require a registered agent with a physical address in the state. The Articles of Incorporation must match the Plan of Conversion on the authorized share count, par value, corporate name, and registered agent. Filing fees generally run from about $100 to $500, with expedited processing available for an extra fee in most states.

When the state accepts the filing, it issues a stamped Certificate of Conversion. That document is your official proof that the LLC became a corporation on the effective date. Keep it with your founding records. Banks, investors, and acquirers will ask for it during due diligence.

The Section 351 Tax Analysis

The conversion itself should trigger no federal income tax if it is structured correctly. Section 351 allows property to be transferred to a corporation without recognizing gain or loss, provided the transferors collectively own at least 80% of the corporation’s stock immediately after the exchange.1Office of the Law Revision Counsel. 26 U.S. Code 351 – Transfer to Corporation Controlled by Transferor The 80% threshold comes from Section 368(c), which requires at least 80% of total combined voting power and 80% of every other class of stock.2Office of the Law Revision Counsel. 26 USC 368 – Definitions Relating to Corporate Reorganizations

In a typical conversion where every LLC member receives corporate stock, this test is almost always satisfied, because the same people own 100% of the entity before and after. The IRS treats a statutory conversion as a deemed contribution of all LLC assets and liabilities to the corporation in exchange for stock, followed by a deemed liquidation of the LLC distributing that stock to its members.3Internal Revenue Service. Revenue Ruling 2004-59 No physical transfer of assets actually occurs, and no tax is triggered.

The Liability Trap Under Section 357(c)

One scenario breaks the tax-free result. Under Section 357(c), if the total liabilities the corporation assumes exceed the total adjusted tax basis of the assets transferred, the excess is treated as taxable gain. This catches businesses that have taken large depreciation deductions, reducing asset basis, while carrying significant debt. Certain liabilities are excluded from the calculation, including those whose payment would give rise to a deduction, such as accounts payable for a cash-basis taxpayer.4Office of the Law Revision Counsel. 26 U.S. Code 357 – Assumption of Liability Run these numbers before filing. If liabilities exceed asset basis, get professional tax advice before converting.

Double Taxation Going Forward

The most consequential long-term change has nothing to do with the mechanics of the filing. C Corporations are taxed twice. The corporation pays federal income tax on its profits at a flat 21% rate. When after-tax profits are distributed to shareholders as dividends, shareholders pay tax again on the distribution at their individual rates. This second layer is the main reason most small businesses avoid C Corporation status. If you are converting to raise venture capital or prepare for an IPO, the double tax is usually an acceptable cost. If you are converting for other reasons, consider whether an S election, or a Form 8832 check-the-box election to be taxed as a corporation while remaining an LLC under state law, would meet your goals without the structural overhead of an actual entity change.

Section 1244 Stock

Section 1244 is a tax benefit worth capturing at the moment of conversion. If the corporation qualifies as a “small business corporation,” meaning it has received no more than $1 million in total money and property for all stock ever issued, then individual shareholders can treat losses on that stock as ordinary losses rather than capital losses, up to $50,000 per year, or $100,000 on a joint return. The corporation must also derive more than half of its gross receipts from active business operations rather than passive income like rents, royalties, or investment gains, measured over the five most recent tax years before the loss.5Office of the Law Revision Counsel. 26 USC 1244 – Losses on Small Business Stock No special IRS filing is required. The corporation just needs to meet the requirements at the time the stock is issued. Document compliance in the board minutes at conversion so you can prove it later if the question comes up.

Securities Law Compliance

Issuing corporate stock to the former LLC members is a securities transaction, even though no money changes hands. Federal securities law requires either SEC registration or a valid exemption. Private conversions almost always rely on an exemption, but you have to identify the right one and follow its rules.

The most commonly used is Rule 506(b) of Regulation D, which permits an unlimited raise through a private placement without registration. Under 506(b) you can issue shares to an unlimited number of accredited investors and up to 35 non-accredited investors, provided the non-accredited investors have enough financial sophistication to evaluate the investment. General solicitation and advertising are not allowed.6U.S. Securities and Exchange Commission. Private Placements – Rule 506(b)

Even when an exemption applies, a Form D notice must be filed with the SEC within 15 days after the first sale of securities, meaning 15 days after the conversion’s effective date, since that is when the first shareholder becomes irrevocably committed.7U.S. Securities and Exchange Commission. Filing a Form D Notice Missing the deadline does not void the exemption in most cases, but it can create trouble with state regulators and with future funding rounds. Most states also have their own “blue sky” filing requirements for exempt offerings, so check with the state securities regulator as well.

What to Handle After the Filing

The state filing is the headline event. The administrative follow-up is what keeps the new corporation in good standing, and it is what surfaces during a later audit or funding round when someone skips a step.

The EIN Stays the Same

The converted corporation does not need a new Employer Identification Number. The IRS states directly that you do not need a new EIN when you change your tax classification to a corporation.8Internal Revenue Service. When To Get a New EIN The existing number carries over. Form 8832 is not required when the entity has actually changed its legal form through a statutory conversion; the IRS recognizes the new classification automatically based on the state-law change.9Internal Revenue Service. Form 8832 – Entity Classification Election The corporation files its first Form 1120 for the tax year beginning on or after the conversion date, and the LLC files a final Form 1065 for the short period ending on the conversion date.

Bylaws and the Organizational Meeting

Most states require corporations to adopt bylaws, and the corporation’s organizational meeting is where that happens. The initial board of directors holds its first meeting to adopt bylaws, elect officers, authorize the issuance of stock certificates to the former LLC members, approve bank accounts, and ratify actions taken by the incorporators. Keep detailed minutes and preserve them permanently. They are proof that the corporation observed proper formalities from day one, which matters if anyone later tries to pierce the corporate veil.

The bylaws govern internal operations: how directors are elected and removed, when meetings are held, how votes are counted, what officers the corporation has, and how shares transfer. Bylaws have to comply with the state corporation statute on procedural matters like notice, quorum, and shareholder rights, which makes them less flexible than the LLC operating agreement they replace.

Contracts and Leases

A statutory conversion is designed to preserve existing contracts because the corporation is legally the same entity that signed them. That is the general rule, not a guarantee. The risk lives in anti-assignment clauses in commercial leases and vendor agreements. Courts generally hold that a statutory conversion does not trigger a standard anti-assignment clause, since no actual assignment occurs, but if the contract specifically prohibits transfers “by operation of law” or changes in entity type, the outcome is less certain and courts have split. Review every material contract and lease before converting, and where the language is ambiguous, get written consent from the landlord or counterparty.

Licenses, Permits, and Registrations

Business licenses, professional permits, sales tax registrations, and industry-specific authorizations all need to be updated to reflect the corporate name and entity type. Some licensing agencies treat a conversion as a continuation and amend the existing license. Others require a new application. Contact each agency directly rather than assuming. If the business operates outside its home state, the foreign qualification filings in those states may also need updating. A handful of states require a newspaper publication notice when an entity changes form, which adds a few weeks and a modest cost to the timeline.
