What if I already formed an LLC but now want to raise VC?

You'll need to convert your LLC to a Delaware C Corp. This is a common but expensive process costing $5,000-$15,000+. Your startup lawyer will manage it, but it's a distraction you should have avoided.

How much should I budget for initial legal and accounting setup?

All-in, expect to spend $2,000-$5,000 for incorporation, bylaws, stock issuance, and basic setup with a proper startup law firm. Using a service like Stripe Atlas is cheaper upfront ($500) but doesn't replace tailored legal advice.

Does QSBS apply to state taxes?

It depends. Some states, like New York, conform to the federal QSBS rules, offering huge savings. However, other major states like California do *not* conform, meaning you'd still owe state capital gains tax on your exit.

What's the difference between my 4-year vesting and the 5-year QSBS clock?

They are separate clocks. Vesting determines when you earn ownership of your stock. The QSBS clock determines how long you must hold the stock (from its issue date) to qualify for tax exemption. They often start around the same time but track different things.

Startup Taxes: A Founder's Guide to C Corps, LLCs, and QSBS

Don't guess on your corporate structure. Choosing an LLC to "save on taxes" is a rookie mistake that can cost you millions and kill investor deals. This guide covers why the Delaware C Corp is the standard.

TL;DR: For any startup planning to raise venture capital, the Delaware C Corporation is the required legal structure. This is primarily to enable VC investment mechanics and to qualify founders and investors for the massive tax savings of Qualified Small Business Stock (QSBS). Choosing an LLC is a costly mistake that requires an expensive conversion process later.

Key takeaways

Choose a Delaware C Corp if you ever plan to raise venture capital.
File your 83(b) election within 30 days of receiving founder stock. It's irreversible.
Qualified Small Business Stock (QSBS) can save you over M on a
0M exit. Don't forfeit it.
Converting an LLC to a C Corp costs $5k-
5k in legal fees and wastes weeks of time.
Separate business and personal finances with dedicated accounts from day one.
Use professional services for legal, accounting, and payroll. Don't DIY.

The Only Choice for a VC-Backed Startup

Your first major financial decision isn't your pricing or your first hire. It's your choice of legal entity. Getting this wrong is an unforced error that can cost you millions in taxes, evaporate investor interest, and saddle you with tens of thousands in legal fees to clean up the mess.

Let's cut to the chase. If you plan to raise money from venture capitalists, you must be a Delaware C Corporation. This isn't a suggestion; it's a prerequisite. Any other answer is a sign of inexperience.

Why VCs Mandate the Delaware C Corp

Investors aren't being difficult. They require C Corps for two structural reasons that are core to the venture-capital model: tax incentives and legal simplicity.

1. Qualified Small Business Stock (QSBS) Is a Multimillion-Dollar Reason

This is the single most important concept in this entire guide. Understanding it will put you ahead of 90% of first-time founders.

Under Section 1202 of the IRS code, capital gains from selling stock in a Qualified Small Business can be partially or fully exempt from federal taxes. For a company formed today, that means a 100% exclusion on gains up to the greater of

0 million or 10x your initial investment (cost basis).

This tax break is only available for stock in a C Corporation. LLCs and S Corps are ineligible.

Example: The Cost of Getting it Wrong

You start a company and issue yourself founder shares for basically $0. Seven years later, it's acquired and your stock is worth
2 million.

With QSBS: The first
0 million in gains is 100% free from federal tax. You pay the long-term capital gains rate (let's say 20%) only on the remaining
million. Your federal tax bill: $400,000.

Without QSBS (e.g., you held LLC units): You owe 20% capital gains tax on the entire
2 million. Your federal tax bill:
,400,000.

Choosing the wrong entity just cost you
million in avoidable taxes.

To qualify, your company must be a C Corp, have less than $50 million in gross assets at all times before and immediately after an investment, and be an active business (not a holding company). You and your investors must hold the stock for at least five years. This is why VCs insist you form as a C Corp from day one—to start that five-year clock.
