A clear comparison of LLCs and corporations, including taxes, ownership and when each structure makes more sense.
Quick answer: Both an LLC and a corporation protect owners from business debts. The biggest differences are taxes and formality. An LLC is pass-through by default and has fewer formal rules. A C corporation pays its own federal income tax at a flat 21%, and shareholders pay tax again on dividends, which is called double taxation. Corporations suit businesses that want to raise money from investors or issue stock; LLCs suit most small, owner-run businesses.
Once you decide you want liability protection, the next question is usually whether to form an LLC or a corporation. Both are separate legal entities, and both can protect your personal assets, but they work very differently day to day.
This guide compares them side by side, explains how each is taxed, and shows which situations favour each structure. It is general information for US businesses, not legal or tax advice.

What are the main differences between an LLC and a corporation?
| Feature | LLC | Corporation |
|---|---|---|
| Owners | Members | Shareholders |
| Formation document | Articles of organization | Articles of incorporation |
| Liability protection | Yes, generally | Yes, generally |
| Default federal tax | Pass-through | C corporation pays 21% federal tax |
| Double taxation | No, by default | Yes, on dividends for C corps |
| Formalities | Fewer | Board, officers, bylaws, minutes |
| Raising investment | Harder | Easier, can issue shares |
| Ownership transfer | Depends on operating agreement | Shares can usually be sold |
How are LLCs and corporations taxed?
LLC taxes
By default, the IRS taxes a single-member LLC like a sole proprietorship and a multi-member LLC like a partnership. Profits pass through to owners, who pay income tax and usually self-employment tax.
C corporation taxes
A C corporation files its own tax return and pays federal corporate income tax, currently at a flat 21%. When it pays dividends, shareholders pay tax on them again. This is the “double taxation” that many small owners want to avoid.
S corporation option
A corporation, or an LLC, can elect S corporation status if it meets IRS rules. S corps pass profits through to owners and avoid corporate-level income tax in most cases. See our guide to S corp vs LLC.
A C corporation earns $100,000 in profit and pays 21% federal tax, leaving $79,000. If it pays all of that as dividends, the owner pays personal tax on the $79,000 too. An LLC with the same profit would pass the $100,000 straight to the owner’s personal return, with self-employment tax instead of corporate tax. Which costs less depends on the owner’s tax bracket and plans for the money.
Do both protect you equally?
Both structures create a legal wall between the business and its owners. In most cases, creditors and people who sue the business can only collect from business assets, not your home or personal savings. The protection is similar in both, and it can be lost in the same ways:
- Mixing funds: Using business accounts for personal spending.
- Personal guarantees: Signing loans or leases personally.
- Your own wrongdoing: Fraud, or harm you cause personally, is not shielded.
- Ignoring formalities: Corporations that skip required meetings and records can weaken their protection.
Liability insurance is still worth having with either structure, because it covers claims that the entity’s protection does not.
How much paperwork does each require?
Corporations follow more formal rules. They usually need bylaws, a board of directors, appointed officers, annual shareholder and board meetings, and written minutes. LLCs need an operating agreement and state filings, but generally fewer formal meetings and records. Both need separate bank accounts and good bookkeeping to keep their liability protection.
Whichever you choose, keep a simple “company binder”, digital or paper, with your formation documents, operating agreement or bylaws, EIN letter, state filings and major decisions. It saves hours when a bank, investor or buyer asks for them.
How do ownership and control differ?
In an LLC, members can share profits and control in almost any way they agree in the operating agreement. A member who invests more money could receive a larger share of profit, while another member runs the business day to day.
In a corporation, ownership is split into shares. Shareholders elect a board of directors, the board appoints officers, and officers run daily operations. This structure is more rigid, but it makes it easy to bring in new investors, issue different classes of stock in a C corporation, and transfer ownership by selling shares.
- LLC: flexible profit sharing and simple management.
- Corporation: clear, standard rules that investors understand.
Three friends opening a café formed an LLC so one partner could put in most of the money while another ran the shop. Their operating agreement set out who received what share of profit, which a standard corporation would have made harder.
Which should you choose?
An LLC may suit you if
- You run a small, owner-managed business.
- You want pass-through taxes and less paperwork.
- You do not plan to raise money from outside investors soon.
A corporation may suit you if
- You plan to raise venture capital or offer stock to investors.
- You want to give employees stock options.
- You expect to keep profits in the business to fund growth, where the 21% rate can help.
- You may eventually sell shares or go public.
Two founders building a software startup chose a Delaware C corporation because the investors they spoke to expected it, and they planned to give early employees stock options. A local bakery owner, by contrast, formed an LLC for simple taxes and liability protection.
You can usually convert from an LLC to a corporation later as your plans change, though it involves legal and tax steps. Learn more in our LLC meaning guide and our LLC vs sole proprietorship comparison.
What does each cost to form and run?
Formation fees vary by state, and many states charge similar amounts for LLCs and corporations. Ongoing costs differ more: corporations may need more accounting work for corporate tax returns and minutes, while some states charge annual LLC fees or franchise taxes. LLC University lists LLC filing fees from $35 in Montana to $500 in Massachusetts.

Frequently asked questions
