S Corp to LLC Conversion: Step-by-Step Process and Tax Benefits
Your S Corp served you well during growth, but circumstances change. Maybe you’re adding investors who don’t qualify under S Corp restrictions, or you want more flexibility in profit distributions, or you’re simply tired of the corporate formalities. Converting from an S Corp to an LLC is a legitimate structural move—but it comes with tax consequences that require careful planning.
This guide covers when the conversion makes sense, how to do it, and what to watch out for.
S Corps have restrictions that LLCs don’t. If any of these apply to your situation, conversion may make sense:
Shareholder limitations: S Corps are limited to 100 shareholders who must be US citizens or residents. LLCs have no such restrictions—you can have foreign members, corporate members, or any number of owners.
One class of stock: S Corps can only issue one class of stock. LLCs can create different membership interest classes with varying economic rights.
Flexible profit distributions: LLC members can receive distributions disproportionate to their ownership percentage. S Corp distributions must be proportional.
Reduced administrative burden: LLCs don’t require the same formal meeting and documentation requirements as corporations.
Tax implications of S Corp to LLC conversion
This is where most conversions get complicated, and where getting it wrong is expensive.
Built-in gains tax
When an S Corp converts to an LLC (and the LLC elects to be taxed as a partnership), the IRS may treat certain appreciated assets as if they were sold. Any gain that built up during the C Corp period before the S election was made can trigger the built-in gains tax at the corporate rate. Even if you’ve been an S Corp for years, assets appreciated before the S election can carry this exposure.
C Corp earnings and profits
If your S Corp was previously a C Corp, it may have accumulated earnings and profits (E&P) from the C Corp years. Converting to an LLC while having C Corp E&P can create dividend income for shareholders. A tax advisor needs to review this before you proceed.
S Corp tax treatment after conversion
After conversion, the LLC can elect how it wants to be taxed. Options include sole proprietorship (single-member), partnership (multi-member), C Corp, or S Corp. Yes—an LLC can still elect S Corp tax treatment. This means you might convert the legal entity to an LLC for flexibility while keeping the tax structure you’re used to.
How to convert your S Corp to an LLC
Step 1: Vote and document the decision
Shareholders must formally approve the conversion. Document the vote in corporate minutes per your bylaws requirements.
Step 2: Check your state’s conversion process
Most states allow statutory conversion (the simplest method). Some require a merger: forming a new LLC, merging the S Corp into it, then dissolving the corporation. Verify current requirements with your state’s Secretary of State.
Step 3: File state conversion documents
Submit a Certificate of Conversion and LLC Articles of Organization (or equivalent documents in your state). Filing fees vary by state.
Step 4: Obtain a new EIN
The IRS treats the conversion as a new entity. Apply for a new Employer Identification Number and notify the IRS of your entity election.
Step 5: Update all business records
Transfer bank accounts, update contracts and licenses, notify vendors and customers of the entity change, and update payroll registrations.
Step 6: Close S Corp tax obligations
File a final S Corp return for the year of conversion. The S Corp tax year closes on the conversion date, and the LLC begins its own tax year from that point forward.

When conversion doesn’t make sense
Not every S Corp should convert. If your S Corp is profitable and you’re using the salary/distribution split to reduce self-employment taxes, converting to an LLC taxed as a partnership eliminates that advantage—all pass-through income becomes subject to self-employment tax for active members.
Run the numbers with a tax advisor before deciding. The savings from S Corp tax treatment may exceed the flexibility benefits of the LLC structure.
Get your books ready for the transition
Entity conversions create a natural break in your financial records. The S Corp books close, the LLC books open, and everything needs to transfer cleanly.

FAQs about S Corp to LLC conversion
Can an LLC keep S Corp tax treatment after conversion?
Yes. After converting to an LLC, you can file Form 2553 to elect S Corp tax treatment. The legal entity becomes an LLC while the tax treatment stays the same.
Does converting from S Corp to LLC trigger a taxable event?
It can. Built-in gains tax, C Corp earnings and profits, and asset appreciation can all create tax consequences. Always work with a tax advisor before converting.
How long does an S Corp to LLC conversion take?
State processing times vary from a few days to a few weeks. Expedited filing is available in most states. The administrative work of updating accounts, contracts, and registrations typically takes longer than the state filing itself.
What happens to S Corp losses after converting to an LLC?
Any suspended losses that you couldn’t deduct as an S Corp shareholder due to basis limitations may be lost upon conversion. This is another reason to review the tax implications carefully before proceeding.
