Starting a private practice looks like a stack of paperwork. It isn’t. It’s about ten decisions, and the paperwork follows from them. Most clinicians make those decisions early, in whatever order they happen to come up, and without the information that would have changed the answer. The forms get filed either way. The cost shows up six months later, when a bank, a payer, or the IRS asks a question the early decision didn’t anticipate.
What follows is the set of decisions that shape everything downstream, grouped by when they lock in. The order matters as much as the answers.
Structure: the decisions that are expensive to undo
The first is whether you operate as a sole proprietor or form an entity, and if an entity, which kind. In some states a licensed clinician can form an ordinary LLC; in others the law requires a professional LLC or a professional corporation. That choice comes before anything with your business name on it, because the name on your Articles of Organization is the name your bank, your EIN, and your payer contracts will all need to match.
The second is your legal name and any trade name. The third is your federal tax ID: an EIN from the IRS is free and takes minutes online, but it should be issued to the entity you actually formed. The fourth is a separate business bank account, opened under that EIN, which keeps the liability protection you just paid for from dissolving into commingled funds.
Payment: the decisions that shape your caseload
The fifth decision is whether you take insurance, private pay, or both. This is the one clinicians most often treat as a billing preference. It’s actually a caseload decision. Insurance reimbursement for a 53-minute session is frequently well below a private-pay fee in the same market, which means an insurance-based practice needs more sessions to reach the same income, and it adds credentialing, a diagnosis on every claim, and a payer between you and the client. The sixth decision is your fee itself, which should come from your expenses, your income target, and a realistic weekly caseload rather than from what the clinician down the street charges.
Compliance: the decisions the law makes for you
The seventh, eighth, and ninth decisions are less decisions than obligations with choices inside them: your informed consent, your privacy notice, and, for any client paying out of pocket, a Good Faith Estimate under the No Surprises Act. The content is largely set by law. What you decide is how they fit your actual practice: your cancellation policy, how you handle after-hours contact, whether you see minors.
Caseload: the decision most people skip
The tenth is who you serve and how many of them you can see without burning out. It sounds like a marketing question. It’s a capacity question, and it should come before your fee, not after. A clinician who plans for 30 sessions a week and can sustain 22 has a business plan built on a number that won’t hold.
The order that prevents rework
Entity before name registration, name before EIN, EIN before bank account, payment model before fee, capacity before both. Most rework in a new practice comes from making a later decision before an earlier one: opening an account in a personal name, credentialing under an individual NPI when the contract should belong to the entity, or setting a fee before knowing how many sessions the week can hold. Get the sequence right and the paperwork mostly takes care of itself.
