Entity type selection: three decisions, not one
Entity type selection means three decisions — legal form, tax classification, where you register — plus the questions to ask about defaults and reversibility.
Choosing a business structure is usually described as choosing a level of protection. Entity type selection is better understood as choosing a set of default rules: the ones that apply when you and your co owners have not written anything down.
You will not read those defaults, and almost nobody does. They decide who can commit the business to a contract, what happens to an owner's share when they die or want out, how profit is divided when no split was agreed, and who can force a sale. Every structure has a different set.
The practical question: which defaults can you live with, and which do you intend to override with a document?
This is background rather than advice. The choice has real tax and liability consequences, and an accountant and a lawyer should both see your actual situation before you file anything.
What to take away
- You are making three separate decisions at three different offices: the legal form (sole proprietorship, general partnership, limited partnership, limited liability partnership, limited liability company or corporation), the tax classification (disregarded entity, partnership, S corporation or C corporation), and where you register. Fusing them is why this feels harder than it is.
- The defaults matter most in the situations nobody plans fora death, a fallout, an owner who wants out. Those are the cases where a document you never wrote gets written for you.
- Choose the structure you will actually maintain. An entity that is not kept up costs money and gives you a confidence about liability that will not survive a serious dispute.
Three decisions, three places
The legal form is created by a state, and it determines what the business is as a legal matter: a sole proprietorship, a general partnership, a limited partnership, a limited liability partnership, a limited liability company or a corporation. The tax classification is a separate election made with the Internal Revenue Service, and several classifications are available to more than one legal form. A single-member LLC is by default a disregarded entity, a multi-member LLC a partnership, and a corporation a C corporation unless it elects S corporation status. The IRS sets out which classifications attach to which forms on its page about business structures.
Where you register is a third question, driven by where you actually operate rather than by which state has the friendliest marketing. Registration means filing articles of organization for an LLC or articles of incorporation for a corporation with the secretary of state, and naming a registered agent who has a physical address in that state. The filing fee is set state by state and published on the secretary of state's website, and the amounts differ enough that the fee schedule is worth reading before you assume the cheapest state is the right one. The SBA's guidance on picking a legal form covers the same ground and will also send you to your own state for anything specific, which is the correct answer.
Two federal filings come up more often than the rest. An employer identification number is requested from the IRS on Form SS-4, and it is worth having even when the owner could use a Social Security number, because it keeps the business's tax identity separate from the owner's from the start. The classification election uses Form 8832, or Form 2553 for S corporation status. Neither is filed with the state, and neither substitutes for the formation document.
Nothing forces these three to line up in the obvious way. People find the subject confusing because the popular question mixes a legal form with a tax classification and asks you to pick one. Separate them and each becomes answerable on its own evidence.
The axes that actually differ
Structures differ on a small number of things. Most comparisons list twenty differences, and these are the ones that change a decision: whether the owners are personally liable for the business's debts, whether the entity is taxed once or twice, who is allowed to hold an interest, whether interests can be transferred freely, how the entity is managed by default, and what formalities keep it in good standing.
Six axes that decide entity type
Axis
- Who may own it
- Eligibility limits
- Where a claim lands
- Personal by default?
- How profit moves
- Proportional or allocated?
- Governance machinery
- Required roles and records?
- Ongoing maintenance
- Recurring filings and accounts
- Adding and removing owners
- Default on join or exit
Question to ask
- Who may own it
- Unusual owner breaks it
- Where a claim lands
- Narrower than expected
- How profit moves
- Awkward in some
- Governance machinery
- Unmaintained is worse
- Ongoing maintenance
- Cost recurs forever
- Adding and removing owners
- Expensive disputes
Why it decides
- Who may own it
- Where a claim lands
- How profit moves
- Governance machinery
- Ongoing maintenance
- Adding and removing owners
The question to ask
- Who may own it
- Can anyone hold an interest, including another company, a trust, or a person outside the country?
- Where a claim lands
- Does a business debt reach the owners personally by default?
- How profit moves
- Must profit be shared in proportion to ownership, or can it be allocated differently?
- Governance machinery
- Are there required roles, meetings and records, or is it left to you?
- Ongoing maintenance
- What recurring filings, records and separate accounts does it need every year?
- Adding and removing owners
- What happens by default when someone joins, dies, or wants out?
Why it decides things
- Who may own it
- Some tax classifications carry eligibility limits that a single unusual owner will break
- Where a claim lands
- This is the difference people form entities for, and it is narrower than they expect
- How profit moves
- Separating the two is possible in some structures and awkward in others
- Governance machinery
- Machinery you do not maintain is worse than machinery you never had
- Ongoing maintenance
- This is the cost people underestimate, and it recurs forever
- Adding and removing owners
- The most expensive disputes are about exits nobody planned
Work down that list with your own situation in hand. Most people find that two or three rows eliminate half the options, and the rest of the decision is between structures that differ mainly in maintenance.
The defaults you inherit
Here is the part that gets skipped. Every structure has answers already written for the awkward questions, and they are answers you did not choose.
Defaults you inherit by writing nothing
- Any owner can bind the business
- Death passes interest to an estate
- No exit mechanism or price
- Profit split by ownership share
- Business may dissolve on owner exit
A governing document exists to override these. For an LLC that document is the operating agreement; for a corporation it is the bylaws, usually with a shareholders' agreement beside them; for a partnership it is the partnership agreement. A single-member LLC is not required to have an operating agreement in most states, but without one the state's default rules fill the gap. It is worth writing precisely when relations are good, because that is the only time everyone will agree on what is fair. The version written during a dispute is a negotiation, not an agreement.
What none of these structures does
Four things people expect from a business structure and do not get.
What no structure does
- Does not protect you from your own conduct
- Does not pay claims; insurance does
- Does not survive a personal guarantee
- Does not maintain itself
It does not protect you from your own conduct. If you personally cause harm, the entity does not absorb that.
It does not pay claims. A structure decides who a claim can reach. Insurance decides who pays. A business that forms an entity and then economises on coverage has usually made itself worse off, and the sensible move is to price both before committing to either.
It does not survive a personal guarantee. Signing personally for a lease, a loan or a supplier account puts the obligation back on you regardless of the structure above it. This is the most common way people discover the limit, and the guarantee is usually signed years before the problem.
It does not maintain itself. The behaviors that undermine separation are ordinary ones: mixing money between personal and business accounts, keeping no record of decisions, signing your own name without stating the capacity you are signing in. Those are what a busy person drifts into in year three.
Reversibility: what it takes to change course
Ask about the exit before you choose the entrance. This question is cheap to ask now and expensive to ask later.
Ask about the exit first
- Tax classificationcheck waiting periods
- Legal formconversion cost and tax effects
- Adding an ownereasy or unwinding decisions
- Moving registrationrarely clean
- Closing properlyabandoned entities keep obligations
- Tax classificationcan generally be changed by filing Form 8832, or Form 2553 for S corporation status. A revoked S election generally cannot be made again until the waiting period the IRS sets has run, and going earlier requires the IRS's consent, so it is worth asking about the timing before you make the first election.
- Legal formcan often be converted — a partnership incorporating, or an LLC converting to a corporation — and the path varies a great deal in cost and consequence, including possible tax effects on the conversion itself.
- Adding an owneris straightforward in a partnership or an LLC and requires director and shareholder approval in a corporation.
- Moving where you are registeredusually means a foreign qualification in the new state and a formal withdrawal or conversion in the old one, and it is rarely as clean as forming in the right place to begin with.
- Closing properlyhas its own steps: a final tax return, a dissolution filing with the state, and cancelled registrations. An entity abandoned rather than closed can keep generating obligations.
None of this is a reason for paralysis. It is a reason to ask, for the two structures you are choosing between, what the specific route out of each looks like.
What to work out yourself before you pay anyone
An advisor's time is expensive and the expense is mostly spent extracting facts you already have. Turn up with these written down: who the owners are and what each contributes, how you want profit, loss and decisions divided, where you operate now and where you expect to operate later, whether you will hire, what insurance already covers, what you personally own and owe, and what you want the business to look like in a few years.
Write these down before paying anyone
- Who owns it today and in three years
- What each owner contributes
- Specific exposuresharm, money, contracts, employees, vehicles, premises
- Whether profit stays in or comes out
- Insurance held or quoted
- States where people and work are
- Maintenance you will genuinely do
If you can write that as one paragraph, you have done the part that is yours. What remains is the part where a professional earns the fee.
Common questions
Is one structure generally safer than the others?
Should I form in a state with a reputation for being business friendly?
How urgent is this?
Can I copy the structure a similar business uses?
What is the most expensive thing to get wrong?
How often should I revisit the decision?
