LLC, licenses, and permits for a bounce house business

Before you take your first paid booking, you need to sort out how your business is legally set up and what your city, county, and state require you to have on file. None of it is hard, but it is the kind of paperwork that is easy to skip and expensive to skip. This chapter walks you through the pieces that apply to almost every bounce house operator and points you to where you go to confirm the details for your own location.

One thing up front, and it will come up again: this is not legal advice. It is the standard footwork that most small rental operators end up doing, written down so you know what to look for. Every one of these items varies by state, and some vary by city. Verify what applies to you with your own state and city offices, and when the stakes are real, with a local attorney or your nearest small-business development center. Those centers are usually free and they exist specifically to help people in your position.

LLC or sole proprietor

The first decision is what kind of business entity you run under. Most people starting out face two realistic options: run as a sole proprietor, or form a limited liability company (an LLC).

A sole proprietorship is the default. If you start renting inflatables and never file anything, you are a sole proprietor. There is no paperwork to become one and nothing separating your business from you personally. That is the catch. If someone gets hurt at a setup and the claim goes beyond what your insurance covers, your personal assets — your savings, your vehicle, your house — can be on the line, because in the eyes of the law you and the business are the same thing.

An LLC creates a legal wall between you and the business. If the business is sued, the LLC is what gets sued, and in most cases your personal assets sit on the other side of that wall. For a trade where a child can fall, where wind can lift an unanchored unit, where a stranger’s kid is bouncing on equipment you set up, that separation is worth understanding carefully. It is not a magic shield — you can still be held personally responsible if you are personally negligent or if you sign a personal guarantee — but it changes your exposure meaningfully.

A few things to keep straight:

• Forming an LLC is not legally required to run a rental business. Plenty of operators run as sole proprietors, especially in the first season while they see whether the work sticks.
• An LLC is not a substitute for insurance. It limits which pockets a claim can reach; insurance is what actually pays a claim. You want both. Your coverage decisions are their own topic — see /start/insurance.
• Filing fees for an LLC run about $35 to $500, with most states landing between $50 and $200, and some states also charge an annual fee to keep the LLC in good standing (per LLC University 2025–2026). Look up your own state’s number before you assume.

Whether an LLC is right for you depends on your assets, your risk, and your state’s rules. This is exactly the kind of question a local attorney or a small-business development center can walk you through cheaply. It is not legal advice for me to say the trade carries real physical risk — but the choice of how to structure around that risk is yours to make with someone who knows your situation.

Getting a free EIN

An EIN — Employer Identification Number — is the business equivalent of a Social Security number. Banks ask for it to open a business account. You use it on tax forms. If you ever hire help, you need it to run payroll.

Here is the part that saves you money and aggravation: an EIN is free directly from the IRS at irs.gov, and it is issued immediately when you apply online. That is the only place you should get one.

There is a whole cottage industry of websites that will “help” you get an EIN for a fee, often dressing the page up to look official. You do not need any of them. Go straight to irs.gov, apply through their online tool during their posted hours, and you will have your number before you close the browser tab. Do not pay a third-party site for something the government hands out for free.

You can get an EIN as a sole proprietor too — you do not have to form an LLC first. Many operators get the EIN specifically so they can keep their Social Security number off contracts and forms.

A separate business bank account

Once you have your entity sorted and your EIN in hand, open a business bank account and run every dollar of the business through it.

This matters for two reasons. The first is practical: come tax time, and any time you want to actually know whether you are making money, clean books beat digging through a personal account trying to remember which gas fill-up was for a delivery. The second is legal. If you formed an LLC and then run business income through your personal checking, mixing the two, you undermine the very separation you filed for. Courts can look at that mixing and decide the wall was never really there. Keeping a dedicated account is part of keeping your protection real.

You do not need anything fancy. Most banks offer a basic business checking account, and your EIN plus your formation paperwork is usually what they ask for. Call ahead and ask what they need so you only make the trip once.

Business licenses and sales-tax registration

Now the part that varies the most from one operator to the next: local licensing and sales tax.

Many cities and counties require a general business license or a business tax certificate to operate within their limits, whatever the trade. Some require it only if you have a physical storefront; some require it for anyone doing business in the jurisdiction, including from a home garage. The fee and the rules differ widely from one city and county to the next, so the only reliable answer is the one you get from your own city or county office. Search for your city or county name plus “business license” and start there.

Sales tax is the other piece. In many states, renting equipment is a taxable transaction, which means you may need to register with your state’s tax or revenue department, collect sales tax from your customers, and remit it on a schedule. Some states tax rentals, some do not, and the rate can even shift by county. Getting this wrong quietly for a year is the kind of thing that turns into a bill with penalties attached, so it is worth confirming before your first invoice, not after.

Where to check:

• Your city and county government sites for business license or business tax certificate requirements.
• Your state department of revenue (or department of taxation) for whether equipment rental is taxable and how to register to collect and remit.
• A local small-business development center if the answers are unclear — this is squarely what they help with.

Again, none of this is legal or tax advice. It is the checklist of who to ask. The answers depend entirely on where you operate.

The inflatable-amusement-device rules people miss

Here is the one that catches new operators off guard, because it is specific to what you rent and most people have never heard of it: many states regulate inflatable amusement devices directly.

Bounce houses, slides, obstacle courses — in a number of states these fall under amusement-ride or amusement-device law, the same body of rules that governs carnival rides. Depending on the state, that can mean:

• Annual inspections of your units by a state inspector or an approved third party.
• A permit or operator registration you have to hold before you can legally set up for a paying customer.
• A minimum ride-insurance limit written into the law — a floor your policy has to meet.

And then there are states with almost none of this, where the rules are light or effectively absent. There is no national rule that covers all of it. What applies to you depends entirely on your state, and sometimes there is a specific office — a state amusement-ride safety authority, often housed under labor or agriculture — that handles it.

Before your first paid setup, look up your state’s amusement-ride authority and find out whether inflatables are covered and what they require. Search your state name plus “amusement ride” or “inflatable device” and “permit” or “inspection.” If your state requires a minimum insurance limit, that number needs to shape the policy you buy — one more reason your licensing homework and your /start/insurance decisions are tied together. This is not legal advice; it is a pointer to the office that can give you the real answer for where you operate.

Do the footwork before your first paid setup

Line these up in order and you will not be scrambling: pick your entity and, if you go the LLC route, file it; get your free EIN from irs.gov; open a business bank account; confirm your city and county licensing and your state sales-tax registration; and check your state’s amusement-device rules. Some of this you can finish in an afternoon. The state inspection or permit piece can take longer, which is exactly why you start it early rather than the week of your first event.

Keep every piece of this in the same folder as your contracts and waivers and your insurance certificate, so when a venue, a park, or a customer asks whether you are licensed and covered, you can answer in one message instead of a week of digging. When you are budgeting all of this out, the startup-costs chapter puts the filing fees and registrations alongside the rest of what your first season actually costs.

If you run only a couple of events a month while you get set up, the free tier handles 2 bookings a month, enough to run your first weekends — so BounceDay can hold your booking details while you spend your energy on the paperwork that keeps you out of trouble. That is optional; a notebook works too. The legal footwork is the part that is not optional, and it is the part worth doing right. Verify every item here against your own state and city, and lean on a local attorney or a small-business development center when the answer needs to be certain.
