Opening a studio in Missouri: escrow, a $10,000 bond and untaxed classes

October 14, 2026

This is for anyone opening a Pilates, yoga, barre or boutique fitness studio in Missouri. Missouri has a health spa law, and the Attorney General enforces it. Two choices you make while setting up decide how much of it you meet: whether you take money before you open, and whether anything you sell runs longer than three months and is paid up front.

Take money before opening day and it sits in an escrow account the Attorney General controls, unless you are registered and have posted a $25,000 bond. Sell a six-month pack or an annual paid in full during your first three years and you need a bond of at least $10,000.

Missouri's health spa law and class studios

Section 407.325 defines a health spa as a business “engaged in the sale of memberships in a program of physical exercise, which includes the use of one or more of a sauna, whirlpool, weight-lifting room, massage, steam room, or exercising machine or device.” We read a reformer, a tower, a spin bike or a rower as an exercising machine, so a reformer or cycle studio fits.

A mat-only yoga or barre studio is less clear, because the definition hangs on equipment. The exclusions cover nonprofits like the YMCA, member-owned clubs, self-defense schools “such as judo or karate,” government and nonprofit schools. There is no yoga, dance or instruction-only exclusion. One more exclusion, 407.325(4)(g), covers a business “engaged in the sale of the right or privilege to use such facility when the proceeds of the sale of such rights or privileges accounts for twenty percent or less of the gross annual receipts.” Our reading is that a studio selling classes, which are instruction, rather than the right to use the room could argue it fits, but we found no Attorney General guidance applying it to studios, so ask the Attorney General’s office before relying on it. We would plan as a health spa.

The three-month line

Most of the law attaches to a “health spa contract.” That is an agreement for services “to be rendered over a period longer than three months; and the seller of health spa services receives payment to cover a period more than three months.” Registration, the bond and the required contract clauses all hang on it.

Our reading is that drop-ins, a membership that bills month to month and a pack that expires within three months are not health spa contracts. The Attorney General has published nothing on this, and its own page reads broader. It says health spas new to Missouri “should also file” a bond, and that “Most health spas also must post a bond.” Ask the Attorney General's office before you build your menu on our reading.

Registration

Section 407.327 makes it unlawful to “offer, advertise, or execute” a health spa contract before you are registered with the Attorney General. The fee is $100 per location, every year, and each location registers separately. The statement is signed by hand and notarized. The initial form asks the longest membership you sell and wants copies of all your membership contracts attached.

Registration lasts one year. Under the Attorney General's rule, a renewal filed 30 days late costs $25 more, and at 45 days the registration is forfeited.

The bond, and the way around it in years one to three

Section 407.339 requires a surety bond or a letter of credit from an FDIC-insured bank, filed with the Attorney General per location. The amount turns on how many unexpired contracts longer than three months that location has.

The bond renews every year. It pays members if the studio fails to open within 60 days of their contract or closes before it ends (407.340).

Two exits matter for a new studio. A health spa is exempt from the bond “after such health spa has been engaged in business for three years.” Before that, section 407.339 lets an unbonded studio sell contracts of up to 36 months as long as what is charged each month “does not exceed the monthly fee.” So a 12-month commitment billed in equal monthly payments needs no bond. A six-month pack or an annual paid up front does.

Watch the signup fee. The statute's “monthly fee” leaves out a one-time fee charged at the start. Our reading is that a signup fee makes the first month's charge larger than the monthly fee, which would put that contract outside the exemption. Nothing from the Attorney General addresses it.

Founding members and the escrow account

Section 407.329 is broader than the rest. It covers anyone “selling contracts or health spa services on a prepayment basis,” and a prepayment is any payment made before your doors are “fully open and available for regular use.” That reaches a founding membership paid before opening, whatever its length.

Before the first such sale you notify the Attorney General of the location. Every prepayment goes into an account at a financial institution authorized to do business in Missouri. The bank confirms the account to the Attorney General in writing and agrees not to release the money until the Attorney General authorizes it in writing, after you have opened. The only way out is to be registered and post a $25,000 bond or letter of credit.

In Frontmat a membership can be sold before opening with billing starting on opening day, and a founding membership can be capped at a number of spots. A founding member signed that way pays nothing before you open, so by our reading there is no prepayment to escrow.

What that means for your products

In Frontmat, memberships bill monthly on the member's card through Stripe. There is no annual or multi-month membership product. Class packs can expire after a number of days you set, or never. If you want packs outside the three-month rule, set an expiry under three months. 60 days keeps you well clear.

What a health spa contract must say

• In writing, signed by the member with the date they signed, and a copy handed over at signing (407.334).
• Under the conspicuous caption “BUYER'S RIGHT TO CANCEL”: cancel without penalty within three business days by certified mail or personal delivery, with every dollar refunded within 30 days. Sundays and legal holidays are not business days. The section gives the notice text and you insert your name and mailing address (407.330).
• Cancellation if the member dies or is permanently disabled and cannot use a substantial part of the services for 60 or more consecutive days, with a refund prorated by the weeks left (407.330).
• An extension of the term for time lost to temporary disability (407.330).
• The holder NOTICE printed on its face in at least 10-point boldface (407.335).
• A term of 36 months or less, though it may give the member a right to renew (407.334).

A contract missing the 407.330 clauses is voidable at the member's option, and a member's waiver of them is void. If you close without offering services within 10 miles, members owe nothing more and get a prorated refund (407.332).

Sales tax: instructional classes are exempt

Missouri taxes fees paid in a place of amusement or recreation “except amounts paid for any instructional class” (144.020). An instructional class “includes any class, lesson, or instruction intended or used for teaching” (144.010).

The Department of Revenue applied that to a fitness company in letter ruling 8280 on January 4, 2024. Its per-class, month-to-month and annual memberships were not taxable “because all classes are led by an instructor and Applicant's members cannot use the space or equipment individually.” A letter ruling binds the department only for the business that asked, for three years.

The department's Fitness Centers tax matrix, revised March 28, 2025, lists instructional classes, fitness classes and personal training as exempt. Gym membership fees, guest fees and facility rental are taxable. So are cancellation fees, and the matrix does not say which kind, so ask about late-cancel fees. The state rate is 4.225 percent, plus city and county tax.

So a class-only studio's packs and memberships are in good shape. Open-studio time and renting the room are not. If you sell anything taxable, build the tax into the price or collect it with another tool. Frontmat does not add a sales tax line to packs or memberships today. The matrix says you can request a letter ruling for your own facts.

Your waiver

Missouri enforces a release of your own negligence, but strictly. The lead case is Alack v. Vic Tanny International of Missouri (Mo. banc 1996), which involved a health club contract. As a Missouri appeals court summarized it in Milligan v. Chesterfield Village (2007), the language must be “clear, unambiguous, unmistakable, and conspicuous.” The words “negligence” or “fault” or their equivalents must be used conspicuously. Intentional torts and gross negligence can never be released.

Milligan also discusses a ski-rental release that named negligence and still failed, in part because it was in about five-point type. We found no Missouri appellate decision on a release a parent signs before an injury. The closest case we found is about a release signed after the incident. In Y.W. v. National Super Markets (Mo. Ct. App. 1994), a mother signed away her 11-year-old's claims after a store detained the girl. The court held that “a parent cannot bargain away a minor's right to bring a civil action against an alleged tortfeasor without being duly appointed” by a court. That case did not decide a waiver signed in advance, but on our reading it points against relying on one. If you teach teens, ask a Missouri lawyer.

In Frontmat the waiver is your own text. Members sign it once, at their first booking, with a typed name. We store the time and a fingerprint of the exact wording they signed, so an edit later never changes what an earlier member agreed to. It is plain text, so the conspicuous part is done in CAPITALS. We never supply waiver language.

Workers' comp and texts

Workers' comp is required at five or more employees, counting part-time and family employees. LLC members and corporate officers count toward the five. Sole proprietors and partners do not.

Missouri's no-call law counts a text sent to sell something as a telephone solicitation (407.1095), and bars sending one to anyone on the state no-call list (407.1098). Texts to people who gave permission, or who had business contact with you in the past 180 days, are outside it. A person who gets more than one violating text in 12 months can sue for up to $5,000 per knowing violation (407.1107).

Frontmat sends booking texts only (waitlist offers, confirmations and cancellations) to members who opted in, and stores the time and wording of each opt-in. It sends no marketing texts.

Before you sign anything

1. Decide your menu: what runs past three months, what is paid up front, and whether you take any money before opening.
2. Ask the Attorney General's office whether your menu needs registration. If it does, register each location before you advertise a contract: $100, notarized, with copies of your contracts.
3. If you sell any contract over three months paid in advance in your first three years, file the bond or letter of credit. $10,000 covers 500 contracts.
4. If you take money before opening without the $25,000 bond, notify the Attorney General and open the agreed escrow account before the first sale.
5. Write any contract over three months with the BUYER'S RIGHT TO CANCEL clauses and the holder NOTICE.
6. Price open-studio time, rentals and any cancellation fees with sales tax in mind.
7. Have a Missouri lawyer write the waiver, with negligence named in language nobody can miss.
