Part of Entity type selection: three decisions, not one
Entity type selection case study: the parts worth your attention
Entity type selection case study: an invented three-year decision log, with the real filings and tax defaults it turns on named as they come up.
Everything below is invented. The translator, her clients, her co-owner and every event in the log are constructed to show how a structure decision behaves over three years when it is treated as a running record rather than a single choice. No real business is described. The filings, forms and tax defaults named along the way are real and standard, and each one is identified at the point where it appears.
The format is a decision log, which is what makes an entity type selection case study readable three years later: each entry records what happened, the question it raised, who answered it, what was decided, and what would reopen it. The last of those is the point of the exercise.
What to take away
- The entity was formed in the third entry, not the first. Two earlier triggers turned out to be an insurance question and a paperwork question.
- Every entry names who answered. She answered the fact questions herself; a lawyer and an accountant answered the structure ones; the state office and the IRS answered the ones about records.
- Each decision carried a recheck trigger, so nothing had to be remembered.
- A log like this is a few lines a year, and it turns a vague "should I?" into a dated "what changed?"
Entry 1: the first paying client
A freelance translator takes on her first contract for a commercial client, and asks whether to form anything.
She answered it herself, from the facts. One owner, work done at a desk, no client money held, no staff. The realistic loss is a bad translation that costs a client money, and she has no idea yet whether this lasts a year. So: sole proprietor, deliberately.
She opens a separate account anyway and invoices under her own name.
The log notes the decision and three recheck triggers: a client asks for an entity, a contract is larger than she could absorb losing, or someone else works under her name. Her reasoning for staying put is in working as a sole proprietor.
Entry 2: the procurement form
Month nine. A larger client's onboarding form asks for her business structure and a certificate of insurance. It feels like the trigger.
She read the form properly instead. It accepted "sole proprietor" as an answer; what it actually required was the insurance certificate. Professional liability cover bought, structure unchanged, recheck triggers left as written. The lesson recorded in the log: read what the counterparty requires, not what the request feels like.
Entry 3: other people's work under her name
Month fourteen. Demand outruns her hours and she begins subcontracting to three freelancers. Their work goes to clients under her name.
Forming the single-member LLC
- Choose single-member LLC in home state
- Sign operating agreement as only member
- Reopen business account in LLC name
- Move contracts to the LLC
- Apply for federal identifier after state confirms
A lawyer answered this one, for the first time. The exposure had changed in kind: she is now answerable for errors she did not make. An accountant answered the tax side separately.
She chose a single-member LLC in her home state. The formation document is the articles of organization — the certificate of formation, in some states — filed with the secretary of state or the equivalent state business filing office. She signed an operating agreement even as the only member, and appointed a registered agent to accept legal papers at a street address in the state. Then she reopened the business account in the LLC's name and moved the contracts to it.
She applied for the federal identifier — the employer identification number, on Form SS-4 — only after the state confirmed the filing. The accountant left the default tax classification alone: a single-member LLC is a disregarded entity for federal tax purposes, so the profit still flows onto her personal return and no separate return is filed. A one-year recheck on income under the LLC went into the log. See why the order matters in forming an LLC step by step.
Entry 4: a co-owner
Year two. Her best subcontractor proposes coming in as a co-owner.
The lawyer redrafted the operating agreement covering contribution, decision rights, profit split, exit, valuation. The accountant said a second member changes the tax picture and re-ran the numbers.
He pointed at the IRS description of how it classifies a limited liability company instead of summarizing it. Result: a multi-member LLC, which the IRS treats as a partnership by default — Form 1065 for the LLC, and a Schedule K-1 for each member. Electing S-corp status with Form 2553 was on the table and was declined for now. New agreement signed before the new member's first distribution, and recheck on any further change in ownership.
Entry 5: the second state
Year three. The co-owner moves to a neighboring state and works from there full time. Does the LLC now exist there too?
The lawyer checked the state's own definition of doing business, then answered. Registering an out-of-state LLC is a foreign qualification filing — an application for authority or a certificate of authority, depending on the state — and it comes with a second registered agent in that state to accept legal papers.
Both registered agent arrangements were recorded. Both states' annual report filings — the periodic report most states require to keep an LLC in good standing — were calendared. That role and why a second was needed are in registered agent.
Entry 6: the investor
An outside investor offers money and asks whether they would convert to a corporation.
Nobody answered this one yet. The lawyer priced what a conversion would involve; the accountant priced what it would do to the owners' tax position. Parked, with both prices on file and a trigger: a signed term sheet. Which is where the log currently ends.
What the log shows
Three of six entries changed nothing about the structure, and those were the entries that most needed writing down. Without them the pressure to do something would have won. Every decision was made on a trigger, not a mood.
Professionals were used at entries three, four, five and six, where the questions stopped being fact questions. The state office and IRS were consulted for records and criteria, never for advice.
General reading on structure came from the SBA's page on picking a legal form: background, not the decision. The six decisions, in the order that makes each answerable, are set out in the entity type selection guide.
The entity types a selection decision weighs
The log moved once, but the field it moved across is wider. Each option below is defined by a state filing or a federal tax default rather than by a preference:
- Sole proprietorship.No state filing and no separate return; the profit lands on Schedule C of the owner's personal return.
- Single-member LLC.Created by filing articles of organization with the state. The IRS treats it as a disregarded entity by default, so it is taxed as the owner's sole proprietorship unless an election is filed.
- Multi-member LLC.The same state filing, but the default federal treatment is a partnership: Form 1065, with a Schedule K-1 for each member.
- S corporation.Not a state entity type so much as an election, made on Form 2553, with limits on who may own shares.
- C corporation.A separate taxpayer filing Form 1120. An existing LLC can elect that treatment by filing Form 8832, without forming a new entity.
- Partnership.The default for two or more people carrying on a business together, and it applies whether or not anything is written down.
Keep your own
| Date | Trigger | Question | Who answered | Decision | Reopen when |
|---|---|---|---|---|---|
| Month 1 | First commercial client | Form anything? | Herself | Stay a sole proprietor | A client requires an entity |
| Month 9 | Procurement form | Is this it? | Herself | Buy cover instead | Contract size changes |
| Month 14 | Subcontractors start | Form now? | Lawyer, accountant | Single-member LLC | Ownership changes |
| Year 2 | Co-owner joins | What changes? | Lawyer, accountant | Multi-member, new agreement | Ownership changes again |
| Year 3 | Owner moves state | Register there? | Lawyer, state office | Register, second agent | Anyone moves or hires |
Six columns is what it takes. The last one is the column people skip, and it is the only one that makes the next entry easy. Every event in the right-hand column is also an event that has to be reflected in the public record, which is the subject of updating what you filed.
Common questions
Is this a real business?
No. It is invented in every detail, including the trades, the timings and the outcomes. It exists to show the shape of a decision log, not to be copied.
Why did she form an entity at fourteen months and not at the start?
Because on her facts the earlier triggers were answered by insurance and by reading a form. That is her situation, not a rule. Someone holding client money, employing people, or signing large contracts on day one is in a different position, and only a lawyer looking at the actual facts can say which.
Would the timing be different with a business partner from day one?
Almost certainly, because the defaults that apply to two people working together start running immediately, whether or not anything is written down. That is the case where the cost of waiting is highest.
What would have gone wrong without the log?
The entries that changed nothing would have been re-argued every few months, and the entries that did change something would have lost their reasoning. A year later nobody remembers why the default tax classification was left alone, which makes it hard to know when to revisit it.
