You can change a corporation to an LLC in every state, and the mechanics come down to two decisions: which of three legal conversion methods your state offers, and how the IRS will treat the switch for tax purposes. The tax question matters more than the paperwork. A C corporation conversion is treated as a taxable liquidation and can generate two layers of federal tax; an S corporation conversion with the same owners on both sides is usually tax-neutral. Work out the tax consequences before you file anything.
Start With the Tax Analysis, Not the Forms
The IRS doesn’t care which legal method you use to convert. For a C corporation, it treats the change as if the corporation sold every asset at fair market value and then liquidated. That fiction is what produces the tax bill, and it applies whether you file a one-page certificate of conversion or run a full merger.
For an S corporation, the picture is usually the opposite: an S corp and a default multi-member LLC are both pass-through entities, so a conversion with unchanged ownership percentages is generally a non-event for federal tax purposes. Assets keep their basis. No gain is recognized. Some advisors will suggest electing S corp status before converting to an LLC if the timeline allows, precisely to avoid the C corp liquidation treatment.
Run the numbers before you commit. If your C corporation holds appreciated real estate, equipment, or goodwill, the deemed sale can produce a six- or seven-figure tax bill on a business that never received a dollar in cash.
The Three Ways to Convert
State law determines which methods are available to you. Most states allow at least one, and many allow all three.
Statutory conversion. The cleanest option. You file a certificate of conversion together with the LLC’s articles of organization, and the corporation’s legal existence continues as an LLC. Assets, liabilities, contracts, and pending lawsuits carry over automatically. Where it’s available, this is almost always the right choice.
Statutory merger. If your state doesn’t allow direct conversion, you form a new LLC and merge the corporation into it, with the LLC surviving. Same end result, more steps, more filing fees.
Non-statutory conversion. The last resort. You form a new LLC, transfer every asset and liability from the corporation to it, and then dissolve the corporation. Each asset has to be individually conveyed: separate deeds for real estate, assignments for intellectual property, endorsements for vehicles. Expensive and slow.
What a C Corporation Conversion Actually Costs
Two layers of federal tax, and they can both hurt.
The first hits the corporation. Under 26 U.S. Code 336, a corporation that distributes property in a complete liquidation recognizes gain or loss as if it had sold that property at fair market value.1Office of the Law Revision Counsel. 26 U.S. Code 336 – Gain or Loss Recognized on Property Distributed in Complete Liquidation If your assets have appreciated since the corporation acquired them, that appreciation is taxed now. Net operating losses or capital loss carryforwards can offset some of it, but many small corporations don’t have material carryforwards to work with.
The second layer hits the shareholders. Amounts received in a complete liquidation are treated as payment in exchange for the shareholder’s stock, so shareholders recognize capital gain to the extent the fair market value of what they receive exceeds their stock basis.2Office of the Law Revision Counsel. 26 U.S. Code 331 – Gain or Loss to Shareholder in Corporate Liquidations A long-profitable corporation with low stock basis produces a large shareholder-level gain. A shareholder whose basis is close to fair market value may owe little or nothing at this second level.
There’s also a filing deadline that’s easy to miss. The corporation must file Form 966 within 30 days after the board adopts the plan of conversion.3eCFR. 26 CFR 1.6043-1 – Return Regarding Corporate Dissolution or Liquidation Missing it doesn’t change the tax you owe, but it draws attention.
S Corporation Conversions and the Built-In Gains Trap
An S corporation with the same owners before and after can generally convert to an LLC without recognizing gain. There is one important exception: if the S corporation used to be a C corporation, the built-in gains tax under Section 1374 may apply. This tax targets assets that were appreciated at the moment of the C-to-S conversion. If those assets are sold, or deemed sold, within the five-year recognition period that starts on the first day of S corp status, the net recognized built-in gain is taxed at the highest corporate rate.4Office of the Law Revision Counsel. 26 U.S. Code 1374 – Tax Imposed on Certain Built-In Gains
Once the five years are up, the risk is gone. If you’re inside the window and your business has appreciated assets, waiting to convert can save real money.
Getting Shareholder Approval
The board of directors first adopts a plan of conversion. Then the shareholders vote. Most states require a majority of outstanding shares, but some states or corporate charters demand a supermajority, so check the articles of incorporation and bylaws before you schedule the vote.
Shareholders who vote no may have appraisal rights, sometimes called dissenters’ rights. A dissenting shareholder can demand the company buy back their shares at fair market value instead of being pushed into the LLC. Procedures and deadlines vary by state, but the pattern is a written demand filed before or shortly after the vote. Exercising appraisal rights typically means giving up the right to challenge the conversion itself in court. If the company and the shareholder can’t agree on price, either side can petition a court to fix fair value.
In a closely held corporation, this is where things get expensive. A single dissenter can create a buyout obligation the business didn’t budget for. Have those conversations privately before the formal vote.
The Documents and the State Filing
You’ll produce two kinds of documents: internal governance papers and state filings.
The plan of conversion is the internal foundation. It names the corporation and the future LLC, states how shares convert into membership interests, and sets any conditions. The board adopts it; the shareholders approve it.
The operating agreement replaces the corporation’s bylaws and shareholder agreements. It sets out whether the LLC is member-managed or manager-managed, how profits and losses are allocated, voting rights, and exit procedures. Most states don’t require it to be filed, but without one the LLC falls under the state’s default rules, which rarely match what the owners actually want.
The certificate of conversion (some states call it articles of conversion or a statement of conversion) is the filing that legally executes the change. It goes to the Secretary of State with the LLC’s articles of organization, which formally create the LLC. In some states, one filing does both jobs. Fees typically run from around $100 to several hundred dollars.
Filings are usually submitted online or by mail. Processing takes anywhere from same-day to several weeks. The conversion becomes effective on the state’s approval date or on a future effective date you specify. A small number of states also require newspaper publication of the conversion notice; check your state before assuming the state filing is the last step.
Federal Steps After the State Approves
You may need a new Employer Identification Number. The IRS position is that you don’t need a new EIN if you “convert at the state level and don’t change your business structure,” but changing from a corporation to an LLC is a structural change in most cases.5Internal Revenue Service. When to Get a New EIN When it’s unclear, apply for a new one; the application is free and online.6Internal Revenue Service. Get an Employer Identification Number
If you were an S corporation and want the LLC to keep S corp tax treatment, file Form 2553. Under Treasury regulations, an eligible entity that timely files Form 2553 is automatically deemed to have elected classification as a corporation, so you don’t need to file Form 8832 separately.7Internal Revenue Service. Entities 3 File it promptly. Miss the deadline and the LLC defaults to partnership taxation if it has multiple members, or disregarded entity status if there’s only one.
For C corporation conversions, the corporation files a final corporate return reporting the gain on the deemed asset sale, and shareholders report their capital gains on individual returns for the same tax year.
What to Update Once It’s Done
The state approval is a milestone, not the finish line. Practical work continues for weeks.
- Contracts and leases. This is the step businesses most often underestimate. Review every existing agreement for anti-assignment clauses. A statutory conversion where the same legal entity continues may sidestep some of these clauses; a merger or asset transfer usually doesn’t. Clauses that prohibit assignment “by operation of law” are the ones most likely to bite. Talk to counterparties before they find out from a signature block.
- Licenses and permits. Some agencies treat a conversion as a continuation of the same business; others require a fresh application in the LLC’s name. Check every license the business holds.
- Bank accounts. Update the name on every account. Banks generally want a copy of the approved articles of organization and the operating agreement.
- Insurance. Notify carriers so the named insured matches the LLC. A mismatch can open a coverage gap.
- Creditors, vendors, and customers. Send written notice to anyone whose invoices, payments, or records reference the old corporate name.
Contract review is where a conversion quietly goes wrong. A corporation that has been operating for years may have dozens of agreements with assignment restrictions, and a landlord or major vendor can treat the conversion as a breach if you don’t get ahead of it.
