Do these in order. Several steps are blocked by earlier ones — you can't get a Type 2 NPI without an EIN, and you can't credential without CAQH. Skipping ahead is the main reason this takes people six months instead of three weeks.
Total out of pocket to get legally set up: about $125. Everything else on this list is either free or a monthly service you choose. It is much cheaper than people expect.
Sole proprietor = you, doing business as you. Nothing to file. Simplest, cheapest, and your personal assets aren't separated from the business.
LLC = a separate legal entity. Costs $125 in Florida, adds an annual filing, and creates separation between you and the business.
Most therapists end up with an LLC. Not because it's automatically right — because the separation matters once you're carrying client money and a lease.
Do this: one 30-minute paid conversation with a CPA who works with healthcare practices. Ask two questions: which structure, and how should I be taxed. That conversation is the cheapest money you'll spend all year.
Florida's official business filing site. Ignore every service offering to do this for you for $300 — it's a form, and you can fill it in.
Processed in the order received — usually a few business days. You'll get a confirmation with your document number.
Your business's tax ID. It's what lets you open a bank account and bill insurance without handing out your Social Security number.
Separate from personal. Not "I'll keep track." Separate.
Bring: your EIN letter, your Articles of Organization, and your driver's license.
Any bank works. Local credit unions are often easier for small business than national banks. Ask about monthly minimums and whether they charge for deposits.
Get a debit card on the account and use it for every business expense from that day forward.
Read this before you file anything with your home address on it.
Your Sunbiz filing is public. Your NPI record is public. Payer directories are public. If you use your home address, it is permanently searchable — by anyone, including clients.
Options:
You already have a Type 1 NPI — that's you, the clinician. Your business needs its own Type 2.
This is the single most common thing people discover missing three weeks into a payer application.
Your employer's policy does not follow you out the door.
Common carriers for mental health clinicians: HPSO, CPH & Associates, and the ACA-endorsed Trust. Get quotes from all three — premiums vary more than you'd expect.
Two questions to ask each one:
Common choices for solo practices: SimplePractice, TherapyNotes, and Sessions. Most offer free trials — use them.
Choose for billing, not for note templates. You'll write notes in anything. You'll fight with claims every single week.
What to test during the trial:
Three things. Not thirty.
Nobody enjoys this. It takes an afternoon, and it's the first thing asked for if a complaint ever arrives.
The shared database nearly every payer pulls your credentials from. Get this right and applications move. Get it wrong and they sit.
You must re-attest every 120 days. Put it in your calendar now, as a recurring event.
This is the long one, and it's why the whole checklist is ordered this way.
Florida-specific detail — which payers, the carve-out trap, Medicare, Medicaid — is in getting on insurance panels in Florida.
Start while you are still employed. Applications take three to six months from submission to an effective date. Waiting until after you resign means six months without insurance revenue.
Don't apply to everything. Pick payers by: what your local population actually carries, what each reimburses, and whether they're open to new providers in your area at all.
Expect to chase. Applications go quiet, get lost, and need following up every few weeks.
Free, takes half an hour, and consistently underused by therapists.
Around $29.95/month (verify current pricing at signup). For most new practices it pays for itself with a single client.
What actually matters on the profile:
Every Florida LLC files an annual report between January 1 and May 1. It costs $138.75.
Miss the May 1 deadline and it becomes $538.75. That's a $400 late penalty for forgetting a form.
Miss it entirely and the state administratively dissolves your LLC.
Do this now: put a recurring calendar reminder on March 1, every year, titled "File Florida annual report." Not May 1 — March 1, so you have room.
If you outsource one thing here, make it step 11 — credentialing and paneling. It's slow, procedural, unforgiving of small errors, and every week of delay is a week you aren't paid. It also makes you exactly zero percent better as a clinician.
Mentality Today does credentialing, payer paneling, billing and claims for solo clinicians and group practices nationwide. It's the company I co-founded, so weigh that accordingly — but the advice holds whoever you use.
This checklist is the what. The full guide to starting a private practice in Florida is the why — including the break-even calculator that tells you how many sessions a week you actually need.
