You want to choose the right setup for your new company. That choice can change how much you pay in taxes, where you live, who you work with, and how much risk you take.
The law that creates the big split is found in state business code—such as Texas Title 1 or Delaware Title 6 for LLCs, and the California Corporations Code for corporations—plus Internal Revenue Service rules for taxes. Failing to choose correctly can lead to more taxes, lawsuits, or even losing your company.
By 2025, nearly 74% of new U.S. businesses use an LLC or corporation to shield owners from liability and business debts, according to info from the Census Bureau’s annual survey.

LLCs and Corporations: The Big Split
Business owners must choose a type of company under state law. State statutes like Delaware §18-201 for LLCs and Delaware Title 8 §101 et seq. for corporations outline what you have to do to start, keep, and close the business. These laws give LLCs and corporations legal identity, set out liability rules, and determine how owners do their taxes.
An LLC, or limited liability company, is set up under specific state rules. A corporation is a very old business form, also defined by state law. Both are supposed to stop creditors from reaching your house, savings, or car if your business gets sued or fails. This protection is called a “liability shield,” described in Delaware’s LLC statute for LLCs, and Delaware Title 8 §§ 102(b)(6) and 102 for corporations.
Even though both LLCs and corporations provide an asset protection shield, the rules and tax effects for each are distinct.
What Is an LLC?
An LLC is a flexible legal entity. You can have one member or many. To start an LLC, you fill out and submit a Certificate of Formation—this might also be called an Articles of Organization—to your state and pay a state filing fee. The exact document name and cost differ by state. For instance, Florida has an Articles of Organization and charges $125.
LLC owners are called “members.” These members can be individuals, other companies, or even trusts (depending on state law). Many states, like Texas and Wyoming, let single people own an LLC—that’s called a “single-member LLC.”
LLCs offer simple ownership with strong asset protection. If your business gets sued or has debt, you only risk the money you put in. The law, like Delaware §18-303, keeps personal assets safe, as long as you don’t mix personal and business funds.
LLCs usually do not pay income taxes as a business. Money passes through to each member’s personal tax return. The IRS calls this pass-through taxation, and you report the income on your own Form 1040. You only file a separate tax return (Form 1065) if you have more than one member.
Your LLC runs by an “Operating Agreement.” This is not required in most states, but is a smart move. It sets out who owns what, who can sign contracts, how to resolve disputes, and how profits split.
LLCs are more private because you do not have to say as much about owners and managers on state filings as you do with a corporation in most states (e.g., Wyoming and New Mexico offer high privacy).
Raising money as an LLC is tough. Few big investors or venture capitalists want to buy into an LLC. These investors usually want shares, standard documents, and the structure a corporation offers.
An LLC can be managed either by all members or by a “manager.” A managed LLC means only some people make decisions, even though others get paid from profits.
If your LLC has employees, you must get an Employer Identification Number (EIN). This is a federal tax identification number, and you get it by completing the EIN application at irs.gov. Banks will need your EIN to open a business checking account.
What Is a Corporation?
A corporation is a legal entity set up under state law, usually using an Articles of Incorporation—sometimes called a Certificate of Incorporation. Corporations have strict requirements for naming, reporting, and management.
Shareholders (the owners) buy stock, which gives them rights to vote and get paid dividends when the company earns profits. One person can own all the shares, or there can be thousands.
Corporations shield owners from debts and lawsuits, just like LLCs. Their main state law is usually something like Delaware General Corporation Law or California Corporations Code Section 200. The company itself is a separate person under the law.
A standard or “C-Corporation” pays taxes as a company at the corporate rate—currently 21% federally. When you pay yourself as a shareholder, you pay more tax again as personal income. This is what is called “double taxation,” described in the IRS instructions for Form 1120.
If you choose to be taxed as an S Corporation (by filing IRS Form 2553), you skip corporate taxes. Instead, profits go to shareholders who report the money on their own tax returns. You must meet strict rules—like being a U.S. citizen, having no more than 100 owners, and issuing only one class of stock.
Corporations must follow more detailed rules. By state law, you must write up “bylaws,” keep board meeting notes, and file annual reports. California law and Delaware law both require these filings.
Corporations can raise money from a wide group of outside investors by selling shares. Big banks and venture capitalists want corporations, not LLCs, because shares are easy to sell and split.
When you grow a corporation, control decisions shift to the board and shareholders. In an LLC, members have more power over day-to-day business.
How Federal and State Laws Decide the Game
Every business form is set by state law—not federal law. The federal government regulates only how money and taxes get reported.
States like Delaware, Texas, Florida, and California are popular for filings due to business-friendly policies or low taxes. For example, Delaware Code makes it simple and protects business owners well, but you still have to follow all paperwork rules to keep that protection, as seen in Delaware’s business statutes.
The IRS sets out how LLCs and corporations pay taxes. The rules about S-Corp tax, double taxation, and reporting requirements are found in official documents like the IRS’s LLC guidance and IRS’s Form 2553 instructions.
If you do not file your yearly report or pay state fees, your company can be “administratively dissolved.” This means the state will shut down your company, and you lose your LLC or corporation status.
Some states have unique fees or reporting. For instance, California’s $800 “franchise tax” applies to nearly every LLC or corporation even without income, according to the California Franchise Tax Board.
Blending LLCs and Corporations: S-Corp Elections
Certain rules allow a business to mix features from each. Some LLCs can be taxed as corporations, while some corporations (if they qualify) may be taxed as S-corps.
An LLC can ask the IRS to be taxed as a corporation by filing Form 8832. After that, the LLC can file Form 2553 to be treated as an S Corporation, only if all owners are eligible. To learn more, see the IRS S Corporation election rules.
If you qualify as an S-Corporation, one major benefit is that you can pay yourself a “reasonable salary” and get the rest of your profit as dividends. These dividends often avoid the self-employment tax, but the IRS has strict rules and often audits if owners pay themselves an unreasonably low salary.
Not every LLC or corporation can be an S Corporation. Foreign owners are not allowed. All shareholders must be U.S. citizens or resident aliens, and you can only have one class of stock.
Popular Actions and the Impact: LLC vs. Corporation
| You Set Up as | What Happens Next |
|---|---|
| LLC (no S-Corp election) | Profits appear on personal taxes. Self-employment tax is owed. Less paperwork, but fewer investors. |
| LLC (elects S-Corp status) | Pay yourself a wage; remaining profits not hit by self-employment tax. Must obey rules, or trigger IRS audit. |
| C Corporation | Company pays federal tax, then you pay another tax as an owner. Investors like stock structure. |
| S Corporation | Company skips business tax; profits go to owners’ personal returns. Fewer investors allowed. |
Key Scenarios Real Owners Face
Solo Consultant Wants Lawsuit Protection
Jenny sets up an LLC in Texas because she gives advice and worries about getting sued by a client. She fills out a Certificate of Formation, and gets an EIN.
| Jenny’s Entity Pick | Result with the Law |
|---|---|
| LLC | Jenny’s home and savings stay safe unless she mixes accounts or breaks the law. Her taxes are on her personal return. Adding an investor later will be tricky. |
Startup Needs Millions in Backing
A team of four starts “Nova Solutions.” They want to raise money and grow fast. Investors and banks say they’ll only put money in a corporation.
| Nova’s Decision | What It Made Happen |
|---|---|
| Corporation | The team can sell stock, offer stock options to hire employees, and borrow big money. But they must pay themselves and pay careful attention to IRS double-taxation rules. |
Real Estate Family Business Seeks Tax Edge
Tina and Marcus want to buy single-family rentals. Their lawyer points out that they can have privacy, pass-through tax, and simple rules with an LLC, but could lower self-employment tax by picking S-Corp tax status.
| Setup Picked | How It Played Out |
|---|---|
| LLC w/ S-Corp | They pay themselves a salary. Extra money taken as distributions is not hit by self-employment tax. Their attorney preps an operating agreement and makes sure both are liable if they break state rules. |
Concrete Stories from U.S. States
Sophia used New Mexico to form an LLC for her Etsy shop, paying $50 to file her Articles of Organization. She loves the privacy laws since her name is not listed on public records. Every year, she must file a simple report and pay $25, or her LLC is canceled.
Nova, Inc. filed in Delaware with the Delaware Division of Corporations for $89. Investors joined fast because Delaware’s statutes are flexible, but Nova, Inc. has to hold board meetings and file annual reports or they could lose “good standing.”
Mistakes Businesses Make and What They Cost
- Mixing personal and business money will kill your asset protection, according to several court rulings like Walkovszky v. Carlton, 223 N.E.2d 6 (N.Y. 1966). States and courts might let creditors take your personal savings.
- Failing to file yearly reports or fees gets businesses dissolved by the state. Some states do not warn you before striking your company from the register.
- Misusing S-Corp status (like paying zero salary or skipping tax forms) leads to IRS penalties and loss of S-Corp benefits. The IRS S Corp mistakes guide covers these risks.
- Leaving out an operating agreement or bylaws often leads to owner disputes. Courts use state law to settle the conflict, which rarely works in your favor.
- Guessing all states are the same sets you up for surprise taxes and paperwork. Texas and California have unique rules that others do not.
LLCs vs. Corporations: The Details
| Feature | LLC |
|---|---|
| Taxation | Pass-through by default; S-Corp is optional if you file right paperwork |
| Owners | Members; can be people, corporations, or trusts (most states) |
| Flexibility | High; minimal structure, customizable operation |
| Record Keeping | Easier; fewer legal rules to follow |
| Investors | Hard to attract big outside money |
| Feature | Corporation |
|---|---|
| Taxation | Pays own federal taxes (double taxation unless S-Corp status picked) |
| Owners | Shareholders (must be people or certain entities when S-Corp) |
| Flexibility | Less; strict structure and legal rules |
| Record Keeping | Must keep detailed records, do annual meetings |
| Investors | Attracts outside money, venture capital, easy to issue shares |
When Should I Pick Each One?
LLCs work best for small service providers, e-commerce, real estate, and family businesses. You can run things your way, save on reporting, and get privacy in many states.
Corporations are best for companies wanting venture money, big loans, selling shares, or hiring with stock options. Doctors’ offices and tech startups usually go with corporations.
If you want less paperwork, privacy, and simpler taxes, an LLC is the best fit. For growth and investment, choose a corporation. Both types need careful, separate records, an EIN, and a state agent address.
Do’s and Don’ts—LLC Edition
Do’s:
- Get an EIN even if you have no staff—you need it for business banking.
- Write a strong Operating Agreement to prevent owner fights.
- Keep every cent of business and personal money separate.
- File annual state reports and pay fees—states may cancel your LLC in months if you do not.
- Talk to a tax expert before picking S-Corp tax—mistakes can cost more than what you might save.
Don’ts:
- Don’t ignore filings and public disclosures—missing them leads to dissolution and fees.
- Don’t hide income—the IRS audits heavily, and the fines are harsh.
- Don’t add banned owners (foreign nationals/private companies) if electing S-Corp tax.
- Don’t ignore buy/sell rules for co-owners—disputes end up in court.
- Don’t assume forming your LLC in Delaware or Nevada is a magic fix—home state laws still apply for taxes and suits.

State Law Twists and Details
Some states are strict. California law says you must pay the $800 tax every year, no exceptions. That applies even if your company makes no money. If you forget, the California Franchise Tax Board can shut your LLC or corporation.
New York state wants you to announce a new LLC in two newspapers for six weeks. This gets expensive. Skip it, and your LLC is suspended until you fix things.
Texas is famous for its “franchise tax.” All LLCs and corporations owe this tax and must report to the Texas Comptroller’s office. You will lose your company if you miss any filings for two years.
In Delaware, thousands start LLCs for privacy and easy laws. But if you live or do business in another state, that state’s taxes and rules also apply. This can cost lots more than you planned.
Wyoming and New Mexico offer more privacy in some records, but banks and IRS always need to know who is behind your company. Running the company wrong can pierce the liability shield, and courts can let creditors go after your home.
Florida makes it simple to file online, and your name stays off some public lists. But every state shares business info with the IRS and banks.
Full Steps for Each Type
LLC Start-Up
- Pick a name. You can check state lists online to avoid duplicates.
- File Articles of Organization (or Certificate of Formation) with your secretary of state’s office. The fee is $50-$500 depending on your state.
- Pick and list a registered agent. This must be someone who has a physical address in the state.
- Write a clear Operating Agreement. Spell out who owns what, roles, and how to wind down or add members.
- Obtain an EIN from the IRS. This is necessary for taxes, banking, and payroll.
- Set up a business bank account.
- File state and federal tax reports each year. Check if your state has a franchise tax, business license, or other local paperwork.
Corporation Start-Up
- Confirm your name is unique and available. Include “Inc.”, “Corp.”, or “Ltd.”
- File Articles of Incorporation with your state. The fee is most often $100–$1,000.
- Designate directors, and create bylaws.
- Hold an organizational meeting. Issue shares to founders as set in the bylaws.
- Get your EIN from the IRS.
- Register with state tax agencies if needed.
- Hold annual meetings, record minutes, and file annual reports to stay in compliance.
How to Switch or Wind Down
You can change your LLC to a corporation by filing a “statutory conversion” form in most states. This has a filing fee and needs both members and (if an S-Corp) the IRS to approve the change. Delaware and Texas both allow for conversion using forms from the secretary of state.
To dissolve, follow your operating agreement or bylaws, vote as directed, clear all debts, and file articles of dissolution with the state. If you skip a required step, your state can keep charging you yearly fees—even after you close shop.
Comparing S-Corp Elections by Entity
| Entity Setup | S-Corp Election Allowed? |
|---|---|
| Single-Member LLC | Yes, with requirements |
| Multi-Member LLC | Yes, if paperwork filed |
| C-Corporation | Yes, if shares/owners meet rules |
| Foreign Owners | No |

How Paperwork Impacts Everything
All LLCs and corporations must pick a registered agent. This is a real person or business with a state address. You can’t use a mail drop or PO box in most states. Failing to list a real agent means the state can dissolve your business.
Operating Agreements (LLCs) and bylaws (corporations) are not always required, but serve as critical tools if owners disagree. Many legal fights happen when owners skip these documents or use unclear language, as explained in this law firm analysis of real cases.
If you add or remove owners, you often must file “amendment” paperwork with the state and may need to update your EIN details with the IRS.
Missing one deadline for annual reports often means pricey penalty fees, late charges, or automatic dissolution—some states don’t give notice.
Court Rulings and Precedents
Some key cases show what happens when rules are broken. When business owners treat LLC or corporate funds like their own, courts can “pierce the veil” and make the owners pay for business debts, as in Walkovszky v. Carlton. Texas courts did the same in Castleberry v. Branscum, 721 S.W.2d 270. These real cases show following state law is not optional and courts can wipe out your protection for breaking the rules.
Tips on Naming, Privacy, and Digital Rules
You can’t use confusing or misleading names. State laws guide what is allowed (like banning “bank” or “insurance” unless you’ve got a license). Most states offer instant online name checks.
Privacy rules change state by state. Wyoming, New Mexico, and Delaware keep owner names off most public filings, but banks and the IRS must know exactly who owns every company.
If you do business online, you might need extra licenses or a sales tax permit for e-commerce sales, described in the FTC small business guide. Selling across state lines can trigger “nexus” taxes in multiple states, explained by the Sales Tax Institute’s multi-state guide.
Step-by-Step—Important Details for Every Line Item
- Pick a name: State databases help you pick a unique and legal name. In California, you can do this through the California Business Search site.
- Registered agent: This is a must in all states. Many companies offer cheap registered agent services, but rules require a human, not just a mailbox.
- Paperwork: Some states only take online filings, others want paper with wet signatures.
- Operating Agreement/bylaws: Spells out the details; needed for banks and legal protection, even if it is not filed with the state.
- EIN: Get from IRS.gov free. You’ll need it to open any bank account. You must keep it up to date if you move or change owners.
- Licenses and local rules: Many states want more permits or city business licenses. Check your state’s official business portal for every step.
Liability and Tax Nuances
LLCs shield member assets only if you respect corporate formalities—separate money, clear agreements, and honest reports. One slip opens your home or savings to lawsuits; recent court decisions prove this risk is real.
Corporations have their own double tax risk. If you pay yourself only as dividends, not as ordinary salary, the IRS can deny your deductions and fine you. This happens under IRS audit rules and is detailed in this IRS S-Corp audit summary.
LLCs taxed as S Corps offer smaller owners savings on self-employment tax, but the IRS does look closely at the salary you pick.
Additional Real-World Examples Across States
A Delaware LLC owned by a tech freelancer gives privacy and low annual fees, but if that owner lives in New York, New York wants their own state fees paid and yearly reports filed.
A Nevada corporation pays low state taxes but faces banking and legal headaches if most of business is in California—California will want foreign qualification plus fees.
A multi-member Oklahoma LLC formed with five cousins lets profits split up, but if one cousin goes bankrupt, his share can get dragged into court unless the operating agreement blocks it. Oklahoma statutes on LLCs detail the importance of transferable interest clauses in this situation.
Common Situations Where Mistakes Lead to Trouble
Failing to list a real registered agent means your business could miss court papers or government mail. If the state doesn’t reach you for lawsuits or tax notices, you can lose “good standing” and protection.
Payroll tax mistakes in S-Corps can get expensive fast—payroll taxes are the IRS’s most-audited requirement, and mistakes trigger stiff fines and personal liability, as shown in IRS Notice 784A.
Paying owners whatever they want—without board approval in a corporation—breaks laws about distributions, leading to tax and legal mess. Owners must follow state rules approved in the company bylaws.
Legal Language and What Each Detail Really Means
Words like “limited liability” mean personal savings, car, house, and other stuff you own cannot be taken for business debts—if (and only if) you respect all the rules. The liability shield does not cover fraud or debts you personally guarantee.
Some states let LLCs “series LLCs”—a kind of big business umbrella with many separate projects under one main LLC (see Delaware series LLC statute). Each series is supposed to protect the others, but not all states recognize this, which can cause hard problems if you operate in more than one state.
Managing Growth, Control, and Exit Strategies
LLCs are easy when you want to add family or friends as members. You just change the operating agreement and file a form with the state.
Corporations use stock buy-sell agreements to make sure shares change hands in order. This can help with estate planning or bringing in new investors.
If you want to sell your business, many buyers (especially big ones) prefer to buy stock in a corporation. An LLC interest sale is more private but might mean tougher due diligence.
Compliance: Annual Reports, Meeting Minutes, Tax Filings
Every state charges a renewal or report fee. You must file annual reports with up-to-date info. Some require written meeting minutes—even for a company with only one owner.
IRS filings must match your state ownership list. States and the IRS share data under the Federal-State Information Sharing Program. A mismatch can get the IRS or state tax authorities asking questions.
Even if you make no money, you usually must file annual reports and pay state fees, or your company is suspended. In California, this means you lose the right to sue or defend your company in court.
Recap on Court Rulings, Statutes, and IRS Guidance
When “piercing the veil,” courts look at failure to separate money, skipping required meetings, lying on paperwork, or mixing personal and business actions (see the classic case of Walkovszky v. Carlton). IRS audits of S Corps chase missed salary or fake loans instead of wages.
State codes, like the Delaware General Corporation Law or California Corporations Code, along with IRS forms and publications, are the documents setting all these rules.
Each checklist item—whether naming, getting an agent, writing agreements, or annual filings—comes with direct consequences set out in these statutes and explained by courts and IRS in real legal disputes.
FAQs
Can I run an LLC by myself in every state?
Yes. You can be the only member—called a single-member LLC—in all 50 states. Just file the right formation form and keep business records.
Does double tax hit all corporations?
No. Many small corporations avoid double tax by choosing S-Corp tax status. The company must meet IRS standards for this.
Are non-US citizens allowed in an S-Corp?
No. S Corporations cannot have foreign owners—only U.S. citizens or lawful permanent residents may be shareholders.
Can an LLC keep my savings safe from lawsuits?
Yes. So long as you follow state law, keep money separate, and do not commit fraud or sign personal guarantees.
Is a lawyer required when I open my LLC or corporation?
No. States allow people to do this on their own. However, small mistakes can become expensive later.
Should I file my LLC or corporation in Delaware or my home state?
No. Most owners should file where they live and work. Filing elsewhere often brings double state fees without extra protection.
Is it hard to switch from an LLC to a corporation?
Yes. You must file forms, pay state fees, and meet IRS requirements. If you have investors or multiple members, talk to a professional.
Will my LLC keep my name off public records?
Yes, in some states. Privacy rules vary. Wyoming, New Mexico, and Delaware all offer varying levels of owner privacy. Other states do not.
Can I get venture funding with an LLC?
Usually, no. Most venture or outside investors ask for a corporate structure with shares.
Does an LLC always help me save taxes?
No. LLCs pass income through to your personal tax return. Tax savings depend on your earnings, state, and whether you pick S-Corp status.
