Choosing between an LLC and a C-Corporation is the first structural decision you make as a founder, and it shapes everything downstream: how your profits are taxed, who can own a piece of the company, and how much paperwork you carry every year.
The good news is that the LLC vs C-Corp decision is more predictable than the internet suggests. For most founders it comes down to one question: will you fund this business with its own profits, or with venture capital? Answer that honestly and the entity usually picks itself.
This guide walks through taxation, ownership rules, investor expectations, compliance, and conversion paths, then closes with a decision framework by founder type. If you want a shortcut, the entity quiz takes about two minutes.
The short answer
Pick an LLC if you are bootstrapping, freelancing, running an agency, or selling on Amazon, and especially if you are a non-US resident. It is simpler, cheaper to maintain, and profits pass straight through to you without a second layer of tax.
Pick a C-Corp if you are building a venture-scale startup and plan to raise from US investors, grant stock options to employees, or eventually go public. VCs expect a Delaware C-Corp, and fighting that expectation costs more than the double taxation does.
Taxation: one layer or two
How an LLC is taxed
An LLC is a pass-through by default. The company itself pays no federal income tax: profits flow to the owners, who report them on their own returns. One layer of tax, and early losses can typically offset other income.
For non-US owners the mechanics differ but the principle holds. A single-member foreign-owned LLC files Form 5472 attached to a pro-forma 1120 every year, and the penalty for missing it is $25,000. If you have US-source effectively connected income you may also need a 1040-NR, and a multi-member LLC files Form 1065 with K-1s plus foreign-partner withholding on Forms 8804 and 8805. Brio’s US tax filing service handles all of these.
How a C-Corp is taxed
A C-Corp is a separate taxpayer. It files its own return and pays the flat federal corporate rate, currently 21 percent, on its profits. When it pays those profits out as dividends, shareholders are taxed again. That is the double taxation everyone warns you about.
In practice, early-stage startups rarely feel it. They reinvest everything and pay no dividends, so the second layer never triggers. Double taxation mostly hurts profitable businesses that want to pull cash out, which is exactly the kind of business that should usually be an LLC.
Ownership rules and investor expectations
An LLC is owned by members holding membership interests, and it is extremely flexible: any number of members, any nationality, companies as owners, even profit splits that do not match ownership percentages.
A C-Corp is owned by shareholders holding stock, and that rigidity is a feature for investors. Stock comes in standard classes, supports employee option pools, and sits on decades of Delaware case law that makes every document predictable. This is why VCs, accelerators, and institutional investors almost universally require a Delaware C-Corp before they wire money.
C-Corp stock can also qualify for the Qualified Small Business Stock exclusion, which in most cases lets early shareholders exclude a large share of capital gains after a five-year hold. LLC interests do not qualify. If a big exit is the plan, that alone can tilt the math.
Compliance: what each demands every year
An LLC travels light: a state annual report in most states, a registered agent, and the federal filings that match your ownership. No required board, no bylaws, no annual shareholder meetings, no stock ledger.
A C-Corp carries corporate formalities on top of its tax return: bylaws, a board of directors, annual meetings, written consents, a stock ledger, and franchise tax. Delaware calculates corporate franchise tax from authorized shares, which surprises founders who authorize millions of them. None of this is hard, but it is real overhead whether or not you ever raise.
One note on FinCEN beneficial ownership reporting: under the 2025 interim final rule, US-formed companies are exempt, while foreign companies registered to do business in the US must still file. These rules can change, so confirm the current requirements before relying on an exemption.

The S-Corp election: a sidebar for US persons only
You will hear about S-Corps as a way to cut self-employment tax. An S-Corp is not a separate entity type: it is a tax election an LLC or corporation can make, letting a profitable owner take a reasonable salary and receive remaining profits as distributions that avoid self-employment tax.
The catch that matters here: S-Corp shareholders must be US citizens or residents. There is also a 100-shareholder cap and a single class of stock, which rules out venture rounds too. Non-resident founders can cross it off the list entirely. US persons with steady profits should model it with an accountant, and a free tax consultation is a sensible first step.
A decision framework by founder type
Bootstrapped founders, freelancers, and agencies
LLC. You get one layer of tax, minimal formalities, and full freedom to pull profits out whenever you like. If your profits grow and you are a US person, you can layer the S-Corp election on later without changing entities.
VC-bound startup founders
Delaware C-Corp, and do not overthink it. Every template your investors and lawyers use, from SAFEs to option plans to board consents, assumes Delaware corporate law. Starting anywhere else usually means paying to convert right before your first priced round anyway.
Non-US residents
An LLC is typically the right default: pass-through treatment, no citizenship requirements, and a setup you can complete remotely. In many cases a non-resident with no US presence and no effectively connected income owes no US federal income tax at all, though the filing obligations above still apply and your home country taxes you under its own rules. Wyoming is the usual pick for cost and privacy; see Wyoming vs Delaware for non-residents for the head-to-head. The one exception: if US venture capital is the explicit plan, go straight to the Delaware C-Corp.
Switching later: conversion paths
This decision is not permanent. LLC to C-Corp is a well-worn path: many states offer statutory conversion, Delaware makes it routine, and bootstrapped companies convert all the time when a serious round appears. Do it before the round is priced, since converting at a high valuation can create tax friction.
C-Corp to LLC is the painful direction. Unwinding a corporation is generally treated as a taxable liquidation, so appreciated assets can trigger tax on the way out. That asymmetry is a good reason to default to the LLC when you are unsure: the cheap conversion runs in the direction you would actually need.
Whichever you choose, formation is the easy part. Brio forms your LLC for $1 plus the state fee, typically in 3 to 7 business days, with EIN, registered agent, and a US mailing address handled in one place. Non-resident founders can follow the full playbook in our guide to starting a US business as a non-resident.
Frequently asked questions
Can a non-US resident own a C-Corp?
Yes. C-Corps have no citizenship or residency restrictions on shareholders, and neither do LLCs. The restriction people half-remember belongs to the S-Corp election, which is limited to US citizens and residents.
Does an LLC pay less tax than a C-Corp?
Usually, if you are taking profits out. LLC profits are taxed once on the owners’ returns, while C-Corp profits are taxed at 21 percent and again as dividends. A startup that reinvests everything may never feel that second layer, so the answer depends on what you do with the money.
Can I start as an LLC and convert to a C-Corp when I raise?
Yes, and it is common. Statutory conversion to a Delaware C-Corp is routine, and investors are used to seeing it. Plan the conversion before your round is priced to keep the tax picture clean.
What does a foreign-owned LLC file if it made no money?
A single-member foreign-owned LLC must still file Form 5472 attached to a pro-forma 1120 every year, even with zero revenue. The penalty for skipping it is $25,000, which makes it the one deadline no non-resident owner should miss.
Do investors ever fund LLCs?
Occasionally. Some angels, family offices, and revenue-based lenders will. Institutional VCs almost never do, because their fund structures and legal templates are built around Delaware C-Corp stock. If venture funding is the plan, form the C-Corp and skip the conversion.
