Convert LLC to C-Corp in Delaware: Process and Tax Traps

Step-by-step guide to converting your LLC to a Delaware C-Corp before fundraising. Covers statutory conversion, tax implications, and optimal timing.

By Omer Aydin · 2026-08-19

The decision to convert an LLC to a C-Corp in Delaware typically arrives at a specific moment: a VC term sheet lands, and the investor's counsel requires a Delaware C-Corporation as a condition of funding. At that point, founders face a choice between statutory conversion (clean, fast, same EIN) and dissolution-plus-reincorporation (messy, slower, new EIN). Getting the mechanics and timing wrong can trigger phantom income, double taxation, or weeks of legal delays that jeopardize the funding round.

This guide covers both conversion paths, the tax consequences of each, the optimal timing window, and the documents you need to have ready before starting.

Two paths: statutory conversion vs. dissolution and reincorporation

Factor	Statutory Conversion	Dissolution + New Corp
EIN	Same EIN carries over	New EIN required
Contracts/licenses	Automatically transfer	Must be reassigned
Timeline	1 to 3 weeks	3 to 6 weeks
Tax event	Potentially taxable (depends on structure)	Taxable exchange
State support	Delaware, Wyoming, and most states	All states
Complexity	Moderate	High

Statutory conversion is almost always the better path for funded startups. Delaware's LLC Act (Section 18-214) and General Corporation Law (Section 265) explicitly authorize conversion of an LLC into a corporation without dissolving the original entity.

What are the tax consequences of converting an LLC to a Delaware C-Corp?

Converting an LLC to a C-Corporation is treated by the IRS as a taxable exchange under Section 351 unless specific requirements are met. The LLC members must transfer all assets to the new corporation solely in exchange for stock, and immediately after the transfer, the transferors must control at least 80% of the corporation's voting power and value.

• If Section 351 requirements are satisfied, no gain or loss is recognized at the time of conversion
• If the LLC has accumulated earnings or unrealized appreciation, conversion timing relative to year-end affects whether those amounts are taxed at individual or corporate rates
• Built-in gains from appreciated LLC assets may be subject to corporate-level tax if the C-Corp later sells those assets within five years

Optimal timing for conversion

The best time to convert is before you have significant accumulated earnings or appreciated assets, and before the term sheet arrives. Ideal timing:

1. Pre-revenue or early revenue stage — minimal built-in gains, simple cap table
2. Before the SAFE/convertible note converts — avoids complex equity restructuring during conversion
3. At least 30 days before the funding close — gives time for Delaware processing, IRS notification, and bank account updates
4. Beginning of a tax year — simplifies the short-period return (final LLC return + first C-Corp return)

Converting mid-year creates two short tax periods: the LLC files a final return through the conversion date, and the C-Corp files from the conversion date through year-end.

Step-by-step: statutory conversion in Delaware

Step 1: Approve the conversion

The LLC's members must approve the conversion per the operating agreement. If no specific provision exists, Delaware requires unanimous written consent of all members.

Step 2: Draft the Certificate of Conversion and Certificate of Incorporation

Two documents filed simultaneously with the Delaware Division of Corporations:

• Certificate of Conversion (Section 265) — identifies the converting entity, its jurisdiction, and the effective date
• Certificate of Incorporation — the standard charter for the new C-Corp (authorized shares, par value, registered agent)

Step 3: File with Delaware

Filing fee: $89 for the Certificate of Conversion + $89 for the Certificate of Incorporation + any expedite fees. Standard processing takes 5 to 7 business days; 24-hour expedite is available for $100.

Step 4: Adopt corporate bylaws and issue stock

Immediately after conversion, the new corporation must:

• Adopt bylaws
• Appoint initial directors
• Issue stock certificates to former LLC members in proportion to their membership interests
• File an 83(b) election if any stock is subject to vesting

Step 5: Update the EIN and bank accounts

Notify the IRS of the entity type change (no new EIN needed for statutory conversion). Update your bank to reflect the new corporate name and structure. Lovie's entity management tools handle these notifications automatically.

Common mistakes that cost founders money

1. Converting after a large revenue month — creates built-in gain that may be taxed at corporate level
2. Forgetting the final LLC tax return — the IRS expects a short-period return through the conversion date
3. Not filing 83(b) elections for vesting stock — if founder stock vests post-conversion, the 30-day 83(b) clock starts at stock issuance
4. Choosing dissolution instead of conversion — forces contract reassignment, new EIN, and potential sales tax on asset transfer
5. Converting in a state that doesn't support statutory conversion — requires domestication to Delaware first

How Lovie handles the conversion

Lovie's formation platform supports direct statutory conversion for LLCs formed through the platform. The system generates both certificates, files with Delaware, updates your EIN classification with the IRS, and restructures your cap table from membership units to authorized shares. The entire process completes in 5 to 10 business days with standard processing.

FAQ

Do I need a lawyer for LLC to C-Corp conversion?

For simple single-member LLCs with no debt, contracts, or IP licensing complications, the conversion is straightforward enough to handle through an automated platform. For multi-member LLCs with complex operating agreements, investor SAFEs, or significant IP, legal counsel is recommended to ensure the conversion agreement properly addresses all member interests.

Can I convert a Wyoming LLC to a Delaware C-Corp?

Yes. This is called a "cross-state conversion" or "domestication." Wyoming and Delaware both support it. The LLC first domesticates to Delaware (becoming a Delaware LLC), then converts to a Delaware C-Corp. Alternatively, you can form a new Delaware C-Corp and merge the Wyoming LLC into it.

What happens to my operating agreement after conversion?

The operating agreement terminates upon conversion. It is replaced by the Certificate of Incorporation, bylaws, and any stockholders' agreement. All rights, obligations, and economic interests defined in the operating agreement must be mapped into the corporate structure.
