Plenty of startups begin life as an LLC. Then the company starts to look like a venture-scale startup, and the LLC becomes the wrong container. Investors want preferred stock, employees want options, and founders want the QSBS clock running. All three point the same direction: converting your LLC to a C corporation.
In Delaware, conversion is a well-worn path with a statutory process, predictable fees, and, in most cases, no tax bill. This guide covers why founders convert, the three ways to do it, what it costs, and the tax and QSBS consequences to understand before you file.
Founders convert an LLC to a C corp mainly for venture capital, stock options, and Qualified Small Business Stock (QSBS) benefits.
There are three methods: statutory conversion, statutory merger, and a nonstatutory assets-over transfer. Delaware statutory conversion is the simplest for most companies.
Delaware charges $164 to file a one-page certificate of conversion plus a minimum of $109 for the certificate of incorporation filed with it.
The conversion is generally tax-free under Section 351 if the requirements are met, but liabilities exceeding basis or negative capital accounts can trigger gain.
Your five-year QSBS holding period starts at conversion, not at LLC formation, so converting earlier is usually better.
Why founders convert an LLC to a C corp
Three forces drive nearly every LLC-to-C-corp conversion.
Venture capital requires it. Institutional investors buy preferred stock in Delaware C corporations. Most funds cannot or will not invest in LLCs because pass-through income creates tax headaches for their own limited partners. If you are raising a priced round, expect conversion to be a closing condition. Our guide to the Delaware C corp covers why this structure became the standard.
Stock options need stock. Standard employee equity, including incentive stock options and the tooling around them, is built for corporations. LLC profits interests exist, but they are harder to explain, harder to administer, and unfamiliar to most startup employees.
The QSBS clock. Qualified Small Business Stock under Section 1202 can exclude millions of dollars of gain from federal tax at exit, but only stock in a C corporation qualifies, and only after a multi-year holding period. That holding period does not start while you are an LLC. Every month you wait to convert is a month added to your exit timeline. See our QSBS eligibility guide for the full requirements.
The three ways to convert
1. Statutory conversion (the default for Delaware)
Delaware law lets an LLC convert directly into a Delaware corporation by filing conversion paperwork. The entity continues without interruption: contracts, bank accounts, EIN, and property carry over automatically. Whether your LLC is a Delaware LLC or an out-of-state one converting into a Delaware corporation, this is almost always the cleanest route.
2. Statutory merger
You form a new C corporation, then merge the LLC into it, with the corporation surviving and members exchanging their LLC interests for stock. This is the classic workaround for states that do not allow statutory conversion. It reaches the same end point but requires a second entity, a merger agreement, and merger certificates, so it means more paperwork and legal review.
3. Assets-over (nonstatutory) transfer
The LLC contributes its assets and liabilities to a newly formed corporation in exchange for stock, then liquidates and distributes the stock to its members. This manual method is usually reserved for unusual situations, such as leaving specific assets or liabilities behind, and creates the most opportunities for error. Do not choose it without counsel.
Delaware statutory conversion, step by step
For a Delaware LLC converting to a Delaware C corporation, the process looks like this:
Approve the conversion. Members approve the plan of conversion per your operating agreement, typically by written consent. Document how LLC units map to shares of stock.
File the certificate of conversion. Delaware's filing fee is $164 for a one-page certificate, plus $9 for each additional page.
File the certificate of incorporation simultaneously. Delaware requires it to be filed together with the certificate of conversion. The minimum filing fee is $109, and it rises with your authorized share count. Most startups authorize 10,000,000 shares of common stock at $0.00001 par value.
Adopt corporate governance. Approve bylaws, appoint the initial board, and issue stock certificates or book entries to the former members according to the agreed mapping.
Handle post-conversion housekeeping. Update your registered agent record, notify the IRS of the classification change, update contracts and payroll, and consider 83(b) elections if any founder stock is newly subject to vesting. Deadlines here are unforgiving: 83(b) elections must be filed within 30 days.
Most straightforward conversions take one to three weeks, and Delaware offers expedited processing for an extra fee if you are up against a financing deadline.
Tax consequences of converting
An LLC-to-C-corp conversion is generally treated as the members contributing the LLC's assets to a corporation in exchange for stock. Under Section 351 of the tax code, that exchange is tax-free if the people transferring property control at least 80% of the corporation immediately afterward, which is nearly always true in a conversion.
Two exceptions catch founders off guard:
Liabilities exceeding basis. If the LLC's liabilities are greater than the tax basis of its assets, the excess is generally taxed as gain under Section 357(c). This shows up in companies that borrowed heavily or took large depreciation deductions.
Negative capital accounts. Members with negative capital accounts, often the result of distributions or allocated losses exceeding contributions, can recognize gain at conversion.
A lightly capitalized software startup with no debt usually sails through tax-free. A company with loans, real assets, or a complicated distribution history should model the conversion with a tax advisor first. This is general information, not tax advice.

What conversion means for QSBS
QSBS is often the biggest financial reason to convert, and the timing rules matter:
Your five-year clock starts at conversion. The Section 1202 holding period begins when you receive stock in the C corporation, not when you formed the LLC. Convert in 2026 and your earliest 100% exclusion window opens in 2031.
Pre-conversion appreciation is a double-edged nuance. Any value the business built up during its LLC years is treated as built-in gain that does not qualify for the exclusion if you later sell. But that same built-in value becomes your stock's basis, which raises the ceiling on your exclusion cap, since the cap is the greater of a flat dollar amount or 10 times your basis. In plain terms: LLC-era gain is not excluded, but it can enlarge the shield around your post-conversion gain.
Converting earlier is usually better. The lower the company's value at conversion, the more of your eventual exit qualifies, and the sooner your holding period ends.
The rules changed meaningfully for stock issued after July 4, 2025, including partial exclusions starting at year three. Our QSBS eligibility guide walks through the current requirements.
Timeline and costs
For a typical Delaware statutory conversion:
State fees: $164 (certificate of conversion) + $109 minimum (certificate of incorporation), plus more for extra pages, higher authorized shares, or expedited service.
Legal fees: Roughly $1,500 to $5,000 for a simple conversion handled by a startup attorney, and more if the cap table is complicated.
Ongoing costs: As a corporation you will file a Delaware annual report ($50) and pay Delaware franchise tax, which is a minimum of $175 per year using the authorized shares method and $400 using the assumed par value method.
Timeline: One to three weeks for a simple conversion, longer if members negotiate the unit-to-share mapping.
When to involve a lawyer
For a single-member Delaware LLC with no debt and no outside investors, conversion is close to mechanical. For anything else, bring in counsel: multiple members with different economics, profits interests or convertible instruments outstanding, meaningful liabilities, an out-of-state LLC, or a conversion tied to a financing. The legal fees are small next to the cost of a botched cap table or a surprise tax bill.
Starting fresh instead? Skip the conversion entirely
If you have not formed your entity yet and you know you are building a venture-scale company, the simplest move is to start as a Delaware C corp and never convert. Rho Incorporation sets up an attorney-reviewed Delaware C corporation for $400, refunded when you open a Rho account and keep a $10,000 average checking balance for 60 days. Your registered agent is included for the first year, your SS-4 (EIN application) is prepared and submitted for you, 83(b) election support is built in, and you get same-day access to Rho business banking once approved. Your QSBS clock starts on day one.
FAQs
In Delaware, no. Statutory conversion requires member approval, a certificate of conversion, and a certificate of incorporation filed together, and the entity continues uninterrupted with the same EIN and contracts. Complexity comes from the cap table and taxes, not the filing itself.
Delaware's state fees are $164 for a one-page certificate of conversion plus a minimum of $109 for the certificate of incorporation. With attorney fees, most simple conversions land between $2,000 and $6,000 all-in, and complicated cap tables cost more.
Most conversions are tax-free under Section 351 because the members control the corporation after the exchange. Gain can be triggered if the LLC's liabilities exceed the tax basis of its assets or if members have negative capital accounts, so companies with debt or a complex distribution history should model the conversion with a tax advisor first.
For venture-backed startups specifically: institutional investors require preferred stock in a C corporation, standard stock option plans need corporate stock, and only C corp stock can qualify for the QSBS exclusion at exit. For small businesses that will never raise venture capital, an LLC's pass-through taxation is often the better fit.
Yes. Your Section 1202 holding period begins when you receive C corp stock at conversion, not when you formed the LLC. Appreciation from the LLC years does not qualify for the exclusion, though it does increase your stock basis, which can raise your exclusion cap. The earlier you convert, the more of your exit can qualify.
Most conversions are tax-free under Section 351 because the members control the corporation after the exchange.

In a Delaware statutory conversion, contracts, bank accounts, the EIN, and property carry over automatically because the entity continues without interruption. No new EIN is required and contracts do not need to be reissued.
Key follow-up tasks include updating your registered agent record, notifying the IRS of the classification change, updating contracts and payroll, and filing any 83(b) elections within 30 days for founder stock subject to vesting. Missing the 83(b) deadline in particular can have significant tax consequences.
If you have not yet formed an entity and know you are building a venture-scale company, starting directly as a Delaware C corp is simpler. It avoids conversion costs entirely and starts your QSBS clock on day one.
